- 6 or 8 modern cores are enough for gaming; more cores help with video editing, rendering or streaming on the CPU.
- Compare CPUs with gaming benchmarks at the same resolution, not by GHz or core count.
- AMD “X3D” chips have 3D V-Cache and are the fastest for gaming.
- The socket decides the motherboard, and whether you can upgrade the CPU later without changing boards.
- Intel K and AMD X and X3D chips don't come with a cooler: add one to your budget.
1How to choose a CPU for gaming in 2026
Start with what you'll do on the PC. If you'll only play games, the sweet spot is a current-generation 6- or 8-core CPU with plenty of cache, with the rest of the money going to the graphics card, which is what delivers the most FPS. If you also edit video, render in 3D or compile code, then moving up to 12 or 16 cores makes sense.
Next, look at the platform: the socket and the memory it uses (DDR5 today). A CPU on a current platform lets you swap in a faster one in a few years without changing the motherboard.
And finally, balance: the CPU has to keep up with the graphics card. We cover that at the end, under bottlenecks.
2How to tell if one CPU is better than another
The numbers on the box (cores, GHz) are only useful for comparing CPUs from the same family and generation. Across generations the architecture changes: a new 8-core CPU can beat a 16-core chip from a few years ago in games, because it does more work per clock (IPC) and has more cache.
To compare properly:
- Look for gaming benchmarks from independent reviews at 1080p: at that resolution the graphics card holds things back less, so the differences between CPUs show.
- Check the L3 cache: it matters a lot in games. That's why a Ryzen 7 9800X3D, with 96 MB of L3 cache, is faster in games than a 16-core Ryzen 9 9950X with 64 MB.
- Compare generations carefully: the newest series is usually faster per core, but not always in games; that's why benchmarks matter more than the launch date.
- Only use GHz within the same family: between a Ryzen 5 9600X and a Ryzen 7 9700X, clock speed tells you something; between an Intel and an AMD chip, it doesn't.
- Check the power draw (TDP): two similar CPUs can need different coolers and power supplies.
A rule of thumb: if two CPUs perform almost the same in your games, pick the one with the better platform or the cheaper one, and put the difference into the graphics card.
3How to read a CPU name (Ryzen 7 9800X3D, Core Ultra 7 265K)
The names look like codes, but they follow a pattern:
| Part | AMD Ryzen 7 9800X3D | Intel Core Ultra 7 265K |
|---|---|---|
| Tier | Ryzen 7 (tiers are 3, 5, 7 and 9) | Core Ultra 7 (tiers are 5, 7 and 9) |
| Generation | 9 = 9000 series | 2 = 200 series |
| Model | 800 = position within the series | 65 = position within the series |
| Suffix | X = higher clocks; X3D = 3D V-Cache | K = unlocked multiplier (overclocking) |
Other suffixes you'll see: F means no integrated graphics (you must have a graphics card) and G, on AMD, means stronger-than-usual integrated graphics. Intel's previous generation used Core i5, i7 or i9 followed by the generation: the Core i7-14700K is a 14th-gen i7.
Intel's “Plus” models (250K Plus, 270K Plus) are the refresh of the 200 series with more efficient cores: in our catalog, the Core Ultra 5 250K Plus has 6 performance cores and 12 efficient ones, versus 6 + 8 on the 245K.
4Intel or AMD in 2026: which is better for gaming?
For gaming, AMD chips with 3D V-Cache (the X3D models, like the Ryzen 7 9800X3D or 9850X3D) are the fastest right now. Ryzen chips without X3D (9600X, 9700X) are a balanced pick for mid-range budgets. The AM5 platform uses DDR5, and AMD has kept the same socket across several generations (Ryzen 7000, 8000 and 9000), which makes a later CPU upgrade easier.
Intel's Core Ultra 200 series (LGA1851 socket) shines in heavily multi-threaded work, like video editing or rendering, and draws little power in games. 14th-gen Core chips (LGA1700) are still fast and sometimes show up at good prices; if you choose a 13th- or 14th-gen i7 or i9, update the motherboard BIOS, because Intel released microcode fixes for a stability issue on those models.
The practical decision: compare the price of the CPU plus the motherboard for each brand and look at benchmarks in the games you play. Neither is a bad choice within its price range.
5How many cores do you need for gaming, streaming or editing?
| Use | Recommended cores | Examples from our catalog |
|---|---|---|
| Office work and school | 6 | Ryzen 5 7600, Core Ultra 5 245K |
| Gaming (1080p to 4K) | 6 to 8 | Ryzen 5 9600X, Ryzen 7 9800X3D, Core Ultra 5 245K |
| Gaming and streaming | 8 or more | Ryzen 7 9700X, Ryzen 7 9800X3D, Core Ultra 7 265K |
| Video editing, 3D, programming | 12 to 16 or more | Ryzen 9 9900X, Ryzen 9 9950X, Core Ultra 9 285K |
On Intel, count the performance (P) cores: a Core Ultra 5 245K has 6 performance cores and 8 efficient (E) cores. The efficient ones help with background tasks and heavily multi-threaded work, but in games the P-cores are what count.
For streaming, the graphics card changes things: NVIDIA (NVENC), AMD and Intel cards have their own video encoder that streams without loading the CPU. With it, an 8-core CPU is plenty for gaming and streaming at the same time.
6Balancing your CPU and graphics card: how to avoid a bottleneck
A “bottleneck” happens when one part holds the other back. At 1440p and 4K the graphics card is almost always the limit: the CPU has time to spare. At 1080p on a 144 Hz or faster monitor, the CPU works much harder because it has to prepare more frames per second; that's where a weak CPU leaves an expensive graphics card underused.
Rule of thumb: don't pair a high-end graphics card with an entry-level CPU, or the other way around. If in doubt, see how we pair CPUs and graphics cards at each tier in our builds, or build your own in the configurator.
And don't forget the cooler: Intel K and AMD X and X3D chips don't include one in the box (the Ryzen 5 7600 does come with a basic one). Pick a cooler whose wattage capacity is higher than the CPU's TDP; more in the case and cooling guide.
