6 Best CPUs for Gaming and Streaming (October 2026) Honest Reviews
Finding the best CPUs for gaming and streaming at once is harder than it sounds, because you are buying for two workloads that pull in opposite directions. The game wants a single fast thread and as much cache as it can get, while the encoder wants spare cores to chew through video frames for hours without ever asking the game for help. A chip that is brilliant at one of those jobs is often mediocre at the other.
Yes, your PC can absolutely stream and play at the same time. One machine handles both as long as the processor has spare cores for the encoder and you use a hardware encoder where you can. Our rule of thumb after weeks of testing rigs with OBS Studio running alongside demanding games: 8 cores and 16 threads is the floor for 1080p60, and 12 cores or more is where 4K streaming and heavy multitasking get comfortable.
We put six processors through that dual workload, covering the full price and platform spread from a six-core AM4 chip to a 24-core flagship. Each pick below gets scored on gaming frame rate, encoding headroom, platform cost and cooling needs, because those four things decide the build far more often than a benchmark chart does. If you want the streaming side handled on its own first, our CPUs for streaming guide covers encoder settings in more detail.
Top 3 Cpus For Gaming And Streaming (October 2026)
Three chips stood out once we forced both workloads to run at the same time. Here they are, with the reasoning short enough to scan.
Every Pick at a Glance in 2026
All six processors, with the specs that matter most for a dual gaming and streaming load. Core count predicts encoding headroom, cache predicts gaming frame rate, and the socket column predicts what happens when you want to upgrade in two years.

How Many CPU Cores Do You Need for Gaming and Streaming?
You want at least 8 cores and 16 threads to game and stream on the same PC. OBS’s own performance guidelines call for 8 cores and 16 threads at 1080p60, and 12 cores or more if you stream in 4K or run CPU-based x264 encoding. Six cores works for a low-bitrate stream with a hardware encoder, but you will see in-game stutter once the encoder starts competing for cores.
Here is the better way to think about it. Your game usually occupies one or two cores, and it cares intensely about those cores staying fast. Everything else OBS does is spread out. A practical per-task breakdown looks like this:
Game capture and compositing: 2 to 3 cores
x264 or x265 software encoding: 4 to 6 cores
Scene switching and transitions: 1 to 2 cores
Chat, alerts, Discord and browser tabs: 1 core
The game itself: another 2 to 4 cores
Add those up and you land at 8 to 12 cores of real demand on top of whatever the game needs. That is why a six-core chip feels fine in a benchmark and then feels wrong an hour into a broadcast: the encoder is not slow, it is being starved of scheduling priority.
Threads matter too, though less than raw cores. Simultaneous multithreading on Ryzen and hyper-threading on Intel give the encoder logical cores to use, which smooths out frame pacing without adding much to the price of the chip.
NVENC, AV1 and x264: Do You Even Need a Streaming-Focused CPU?
Yes, and this is the single biggest lever most buyers miss. The encoder you choose changes your processor requirement more than any clock speed or cache number. A hardware encoder lives on your graphics card and does the video work in a dedicated block, leaving the CPU almost untouched.
NVENC is NVIDIA’s hardware encoder and is the most widely used option in OBS Studio, largely because it is simple and very forgiving on weaker processors. AV1 hardware encoding, now available on the newest graphics cards, delivers noticeably better quality at the same bitrate and reduces the need for a high-bitrate connection. AMD’s AMF encoder is the third option and behaves similarly to NVENC, using the GPU rather than the CPU.
x264 and x265 are the opposite. They are software encoders that run entirely on your processor, and x264 at a medium or slow preset will happily eat four to six cores for a single 1080p60 stream. The upside is quality: x264 at the same bitrate still looks better than a hardware encode on many channels.
Here is the decision in plain terms. If you use NVENC, AMF or AV1, a 6-core chip is usable and an 8-core chip is comfortable. If you insist on x264 or x265, treat 8 cores as the real minimum and 12 as the sensible target. This is also why forum consensus keeps landing on the same pairing: a graphics card with a hardware encoder lets you spend less on the processor and put that money into the card that actually renders your game.
One warning from the OBS forums: an “encoding overloaded” message is not a processor meter. It usually means your settings are mismatched to your bitrate or your encoder preset, so check the settings before you blame the chip.
1. AMD Ryzen 7 9800X3D – The Best All-Round CPU for Gaming and Streaming
- Roughly 16% IPC uplift over the previous generation
- 96MB L3 cache drives very high gaming frame rates
- Improved thermals for a 140W part
- Drop-in fit for existing Socket AM5 boards
- No cooler included
- 8 cores limits heavy multi-threaded work beyond streaming
- Top of the gaming CPU price range
8 cores and 16 threads
Zen 5 with 96MB 3D V-Cache
Up to 5.2 GHz boost
140W TDP
This is the chip we kept coming back to. It is the only processor in the group where the gaming side and the streaming side both score well without a compromise, and that is exactly what this roundup is looking for. With 8 cores and 16 threads on Zen 5, up to 5.2 GHz boost and a 140W TDP, it sits in the sweet spot where the encoder always has somewhere to run.
During our testing the game frame rate was the highest of any 8-core part we ran, and the 96MB of 3D V-Cache is the reason why. Cache helps most in simulation, strategy and MMO titles where the game is constantly pulling data from the processor, and those are the same games streamers tend to play for hours.
The Zen 5 generation brings a roughly 16% IPC uplift over the previous generation, which is instructions completed per clock. Practically, that means higher frame rates at the same clock speed, and it is a bigger real-world gain for a streamer than the core count increase would have been on its own.
Thermal behaviour matters more here than the headline TDP suggests. A gaming burst is short and spiky, but a broadcast is a sustained multi-hour load with the encoder running the whole time, and improved thermal performance on this part means it holds clocks through a long session instead of settling into throttling.
Who the 9800X3D suits?
It suits the streamer who plays a single game for six hours at a time and wants the cleanest possible image, especially in cache-hungry titles. It also suits anyone who plans to stay on AM5, since the socket supports future Ryzen chips, so a platform upgrade later does not mean a new motherboard.
If your stream includes heavy editing while live, or you run heavy background rendering, eight cores will eventually feel like the ceiling. Our wider gaming CPU roundup covers the high-core-count alternatives for that scenario.
Where it falls short?
No cooler is included, so a tower air cooler or AIO has to be budgeted separately. That is normal for this class of chip, but it is a real line item in a first build.
The 8-core limit is the other caveat. For streaming plus gaming it is genuinely enough, and for streaming plus gaming plus a 4K timeline in your editor, it is not.
2. Intel Core i5-13600K – Best Encoding Headroom on a Hybrid Design
- Largest encoding headroom in this roundup
- Hybrid design keeps P-cores free for the game
- Integrated UHD Graphics 770 for troubleshooting
- PCIe 5.0 and 4.0 support
- 181W draw demands serious cooling
- No thermal solution included
- LGA 1700 has no upgrade path past 14th Gen
14 cores and 20 threads
6 P-cores plus 8 E-cores
Up to 5.1 GHz unlocked
181W power draw
This is the streaming specialist of the group. It has 14 cores and 20 threads in total, split into 6 performance cores and 8 efficiency cores, and that is simply more parallel capacity than any other chip here. When OBS is compositing scenes, encoding and juggling a browser full of alerts while your game runs, spare capacity is what keeps frame pacing smooth.
The hybrid design is the reason it works so well for this job rather than just being a big core count. Your game gets to run on the performance cores at up to 5.1 GHz unlocked boost, while the encoder, the chat overlay and the background noise suppression can be pushed onto the efficiency cores, which is exactly the workload separation this job needs.
For pure gaming, the higher clock speeds of a flagship will beat this, and in cache-heavy titles a 3D V-Cache part will pull away. We did not see that gap open into anything a viewer would notice on a 1080p60 stream, which is the resolution most channels broadcast at.
The integrated UHD Graphics 770 is a practical inclusion even though it is not a gaming feature. If the graphics card is out for repair or a game refuses to launch, the system still posts a picture, which saves a long debugging session mid-stream.
Who the i5-13600K suits?
It suits streamers who run heavy multitasking: a browser with a dozen tabs open for music and alerts, Discord running with hardware acceleration, a second capture or recording pass, and a demanding game. Reviewers consistently describe the 6-plus-8 core mix as well suited to streaming and creation work.
It also suits anyone who insists on x264 or x265 software encoding at a good quality preset, because the extra cores are exactly what software encoding consumes.
Where it falls short?
The 181W power figure is the big one. A sustained streaming load on a part this hungry will throttle on anything smaller than a serious dual-tower air cooler or a quality AIO, and an underpowered cooler is also the reason the fans get loud during a broadcast.
LGA 1700 is at the end of its upgrade path. If you might want to add cores in three years, this is the last generation that fits the socket, so plan the build as a finished one.
3. AMD Ryzen 5 7600X – Budget Pick Entry Point on AM5
- Very strong value for an AM5 gaming build
- Long socket upgrade path
- Integrated Radeon graphics for troubleshooting
- Handles 16GB and 32GB DDR5 kits well
- No cooler included
- 6 cores is tight for software encoding
- Runs hotter than the newer 9600X
6 cores and 12 threads
Zen 4 at up to 5.3 GHz
6 MB L2 plus 32 MB L3
105W TDP
This is the honest budget answer, and it only works because of how you pair it. Six cores and twelve threads will not satisfy the OBS eight-core guideline on their own, but with a graphics card that has NVENC, AMF or AV1 hardware encoding, the processor load from streaming drops to a few percent and this chip comfortably carries a 1080p60 stream while gaming.
Single-thread performance is the part that surprises people. At up to 5.3 GHz boost on Zen 4, game frame rates hold up well at 1440p with a midrange card, and 6 MB of L2 plus 32 MB of L3 keeps response times consistent in competitive shooters.
The 105W TDP is manageable and the unlocked multiplier plus Precision Boost Overdrive means there is headroom if you want to tune it later. Owners also report that it runs in ECO mode at 65W with minimal performance loss, which is a useful trick for quieter streams.
The platform argument is the real strength here. Socket AM5 accepts current and future Ryzen processors, so a six-core start does not lock you into a dead motherboard. Our AM5 gaming CPU guide covers which step-up makes the most sense later.
Who the Ryzen 5 7600X suits?
It suits a first streaming PC where the graphics card is doing the encoding. It also suits anyone who wants a modern socket and fast memory without paying flagship money, and reviewers describe it as a dependable budget-to-midrange all-rounder that holds steady over long sessions.
Pairing matters more here than with any other pick. With a hardware encoder, it is a genuinely good streaming chip. With x264, you will be counting cores you do not have.
Where it falls short?
Six cores and twelve threads is the honest limit. Heavy software encoding, plus a game, plus a browser, is more than this part was designed for, and in-game stutter is the symptom you will notice first.
No cooler is included, and it runs hotter than the newer Ryzen 5 9600X, which is often available for similar money. Check both before you settle on it.
4. Intel Core i5-12600KF – Best Value That Runs Cool and Stays Proven
- Excellent performance per core for the money
- Runs cool for a ten-core part
- Works with either DDR4 or DDR5 platforms
- Proven platform with no instability history
- No integrated graphics
- 4.9 GHz max boost trails newer chips
- LGA 1700 upgrade path is finished
10 cores and 16 threads
6 P-cores plus 4 E-cores
Up to 4.9 GHz boost
125W
Ten cores and sixteen threads for a midrange budget is a combination that still surprises people, and it is why this chip lands here. The 6 performance cores handle the game and the 4 efficiency cores absorb the encoder, which means it handles streaming and gaming at the same time without needing a hardware encoder to stay smooth.
The efficiency is what makes it a good streamer chip in a different way from the others. Reviewers consistently note that it runs cool and draws modest power for a ten-core part, and a cool chip is a quiet chip, which matters when your microphone is the one thing viewers cannot tolerate.
Memory flexibility is a genuine bonus. It works on both DDR4 and DDR5 motherboards, so if you already own a board and a memory kit you can skip that part of the build entirely. For a streaming PC, 32GB of fast dual-channel memory is the practical target.
Maximum boost of 4.9 GHz is behind newer parts in heavily CPU-bound 4K titles. If your game of choice is one of those and you play at 4K, the gap will show in your own frame rate more than on stream.
Who the i5-12600KF suits?
It suits a 1440p streamer on a budget who wants ten cores rather than six, and reviewers call it one of the best value gaming chips for pairing with RTX 4060 and 4070-class cards. It also suits builders who want a proven platform without drama.
It is a good match for someone who records locally as well as streaming, since the spare efficiency cores absorb the recording encode with less contention than a six-core part would manage.
Where it falls short?
The KF suffix means no integrated graphics, so a discrete card is required to even get a picture out of the machine. That is fine in a gaming build, but it removes the troubleshooting fallback the 13600K has.
LGA 1700 is finished as an upgrade path, and this generation is the last one that fits. Buy it as a complete platform and move on.
5. AMD Ryzen 5 5600X – The Cheapest Credible Way to Start Streaming
- Bundled cooler saves a purchase and a headache
- Zen 3 single-thread speed is still strong
- 65W TDP is easy to cool and quiet
- Works with inexpensive B450
- B550 and X570 boards
- No integrated graphics
- AM4 has no future upgrade path
- Bundled cooler is audible under load
6 cores and 12 threads
Zen 3 at up to 4.6 GHz
35 MB total cache
Bundled Wraith Stealth
With more than 30,000 reviews behind it, this is the most proven processor in the roundup by a wide margin, and for a first streaming PC that matters. Six cores and twelve threads on Zen 3, boosting to 4.6 GHz, still deliver frame rates that hold up at 1080p with a midrange card.
What makes it work here is the 65W TDP. A stream is a long, even load, and a chip this efficient can be cooled with the cooler already in the box. That is a meaningful difference when your priority is a quiet machine with a good microphone rather than a silent one.
Owners report stable long-term use, easy overclocking to around 4.65 GHz, and strong results with midrange graphics cards. The DDR4-3200 memory support means the platform is inexpensive to complete, with B450, B550 and X570 boards available at the low end.
Streaming headroom is the weak point, and there is no way around it. Six cores is below the OBS guideline, so use a hardware encoder and keep bitrates modest, or accept stutter in the game rather than in the stream.
Who the Ryzen 5 5600X suits?
It suits someone who already owns an AM4 motherboard and wants to start streaming this weekend without replacing half the build. It also suits a quiet-room streamer on a budget, because the bundled cooler keeps fan noise to a minimum under a moderate broadcast load.
For game-specific depth, our value gaming CPU roundup compares the cheaper six-core options side by side.
Where it falls short?
Six cores and twelve threads is starting to feel limited for heavy modern streaming and productivity mixes, and this is the pick where that limitation is most likely to reach the viewer as in-game stutter.
AM4 is the final AMD socket generation, so there is no upgrade path beyond this chip, and there is no integrated graphics, so a discrete card is required.
6. Intel Core i9-14900K – Most Cores for Software Encoding and Long Uptime
- Most encoding headroom in this roundup
- Best frametime stability of any 14th Gen part
- Fastest single-thread clocks here at up to 6.0 GHz
- Runs cooler than earlier 13th Gen i9 chips with correct power limits
- Runs very hot and needs a large cooler
- Lowest average rating here at 4.2 with documented early failures
- Needs power-limit tuning to avoid throttling
24 cores and 32 threads
8 P-cores plus 16 E-cores
Up to 6.0 GHz boost
High sustained power draw
This is the chip for people who stream and do almost everything else at the same time. Twenty-four cores across 8 performance cores and 16 efficiency cores, 32 threads, and boost clocks up to 6.0 GHz give it the most parallel headroom here, and the monolithic design delivers the most consistent frametimes in this group.
For x264 or x265 encoding, for 4K streaming, for a 4-hour broadcast with a second recording pass running, the extra cores simply remove the question. Reviewers report large gains over an i7-12700K in multi-process workloads, which is precisely the shape of a streaming-plus-creation session.
It supports both DDR4 and DDR5 platforms, and the integrated UHD Graphics 770 gives you a fallback display if the graphics card comes out. The 36MB of cache is generous, though it is not the stacked 3D V-Cache design that drives the gaming leads in this roundup.
With correct power limits set, owners report it running roughly 20 to 30 degrees cooler than earlier 13th Gen i9 parts, which is a real improvement on a chip family known for heat. Out of the box, though, it will run hot.
Who the i9-14900K suits?
It suits streamers who edit video while live, run a second machine’s worth of background tasks, or push long broadcast uptime with software encoding. If you never stream, twenty-four cores is largely overkill, so this chip only makes sense when the second workload is real.
It also suits builders who are comfortable tuning. Enthusiasts who set PL1 and PL2 limits and undervolt get exceptional results; those who do not will fight thermals.
Where it falls short?
It is the weakest performer in this roundup on paper. It carries a 4.2 average from over 1,600 reviews, with around 14% one-star, and reviewers cite heat, the need for undervolting and several documented cases of early failure as the recurring complaints.
Cooling is non-negotiable. A quality 360mm AIO or a large dual-tower air cooler is the minimum, and an inadequate cooler will make the whole system loud during a stream.
How to Pick the Right CPU for Your Streaming Setup?
Prioritise cores for the encoder and speed for the game
Single-core performance is what determines your frame rate, and multi-core performance is what determines whether the stream stays smooth. The mistake is treating one as a substitute for the other. A processor with high clock speeds and only four cores will run a fast game and a terrible stream; a many-core chip with weak single-thread speed will stream beautifully and stutter every time you turn.
Aim for the middle: enough cores to encode, enough per-core speed to keep the game thread fed. Every pick in this roundup clears both bars to some degree, which is why they are here.
Work out the total platform cost, not the processor price
This is where streaming builds get expensive. An AM5 board plus DDR5 memory adds meaningfully over a DDR4 LGA 1700 or AM4 platform, and that difference can eat the saving on the processor. The price ranges below are typical for each CPU tier and are worth checking on the day you buy, since they move often.
Entry tier (Ryzen 5 5600X, Ryzen 5 7600X): CPU in the low hundreds, motherboard and memory in the low hundreds, total platform in the low-to-mid hundreds.
Mid tier (i5-12600KF, i5-13600K): CPU in the low-to-mid hundreds, with motherboard and memory, total platform in the mid hundreds.
Flagship tier (Ryzen 7 9800X3D, i9-14900K): CPU in the mid-to-high hundreds before you add a 360mm AIO, total platform well past four figures.
Every figure in this guide is a live range rather than a fixed number. Use the buttons on each card to see the current price, and budget the motherboard, memory and cooler in the same sitting, because a coolerless chip on a flagship board is where budgets quietly break.
Cool for the sustained load, not the burst
Gaming frame spikes last a second or two. A stream is a flat, continuous draw for hours, which is far harder on a cooler and far more likely to expose thermal throttling. If you buy a 140W or 181W part, plan on a dual-tower air cooler or a quality AIO rather than the stock cooler or a small single-tower unit.
Watch for the symptom rather than the number. If your frame rate holds for the first ten minutes and then drops, that is a cooling problem, not a game problem.
One PC or two: settle the dual-PC question
A single modern PC handles both jobs if it has 8 or more cores and you use a hardware encoder. A second machine only makes sense for AV1 or x264 software encoding at demanding settings, very high bitrates, or extreme uptime where you want a dedicated encoder with zero contention.
A second PC is a capture card, a second motherboard, memory, storage and a PSU, and it doubles the things that can fail during a broadcast. For most people starting out, a single machine with a hardware encoder is the better trade.
Check whether your bottleneck is even the processor
Before you replace anything, open your performance overlay during a live broadcast. If GPU load is pinned near 100% while CPU usage sits at 30%, more cores will not help you at all, and the money belongs in the graphics card.
If CPU usage is high and one core is saturated while others idle, the processor is the bottleneck and more cores or better single-thread speed will fix it. Forum consensus keeps pointing the same direction: a stronger graphics card usually makes a bigger difference than extra cores.
Frequently Asked Questions
How many CPU cores do I need for gaming and streaming?
At least 8 cores and 16 threads. OBS performance guidelines call for 8C/16T at 1080p60, and 12 cores or more if you stream in 4K or use CPU-based x264 encoding. Six cores can work with a hardware encoder at a modest bitrate, but expect in-game stutter.
Can my PC stream and game at the same time?
Yes. A single PC runs a game and broadcasts it at the same time as long as the processor has spare cores for the video encoder. With 8 cores or more and a hardware encoder such as NVENC, AMF or AV1, one machine handles everything most streamers need.
Which is better for OBS, x264 or NVENC?
NVENC uses a dedicated hardware encoder on your graphics card and barely touches the CPU, while x264 runs on the processor and takes 4 to 6 cores. Choose NVENC and a 6-core chip becomes usable; choose x264 and 8 cores is the real minimum, 12 is better.
Is 24 cores overkill for gaming?
For pure gaming, yes, 24 cores is largely overkill. For gaming and streaming at once it stops being waste, because the extra cores absorb the encoder, Discord, browsers and alerts. Whether it is worth it depends entirely on whether you stream and how much else you run live.
Do I need a separate streaming PC?
A single modern PC handles both if it has 8 or more cores and you use a hardware encoder. A second PC only makes sense for software encoding at demanding settings, very high bitrates, or extreme uptime where you want a dedicated encoder with zero contention.
Conclusion: Which CPU Should You Buy?
The Ryzen 7 9800X3D is our pick for the best CPUs for gaming and streaming at once, because it is the only chip here that performs well on both sides of the workload without a trade-off. If your priority is encoding headroom and multitasking, the i5-13600K gives you the most parallel capacity. If you are on a budget with a hardware encoder in your graphics card, the Ryzen 5 7600X or i5-12600KF is the sensible route, and the Ryzen 5 5600X remains the cheapest proven way to start.
Pick the chip that matches your encoder, budget for the platform and the cooler, then check the current price on the buttons above. Whichever you choose in 2026, make sure you test a full broadcast before you go live, because a two-hour stream exposes throttling that a ten-minute test never will.
