Is Intel i7 or i9 better for gaming?
If you‘re building a high end gaming PC, the i9 is better than the i7 for maximum gaming performance. But for most gamers, the i7 hits the sweet spot of delivering excellent performance at a more affordable price.
The i9‘s additional cores, higher clock speeds and advanced optimizations allow it to outpace the i7 in many gaming benchmarks. Let‘s take a closer look at how the i7 and i9 compare to see which is the better choice for your next gaming CPU.
Core Count
One of the biggest advantages of the i9 is its higher core and thread count over the i7. For example, the Intel Core i9-12900K rocks 16 cores (8 performance and 8 efficient) and supports 24 threads.
The Core i7-12700K isn‘t too far behind with 12 cores (8 performance and 4 efficient) and 20 threads. But those extra 4 performance cores and 4 additional threads on the i9 give it a leg up when it comes to parallel processing power.
| CPU | Cores | Threads |
|---|---|---|
| Core i9-12900K | 16 | 24 |
| Core i7-12700K | 12 | 20 |
Those extra cores and threads really come in handy when playing games that are optimized for multicore processing. Titles like Assassin‘s Creed Valhalla can experience up to a 15% fps increase on the i9 over the i7.
So for gaming on CPU intensive games that leverage multiple cores, the i9 is the clear winner. But there are still many games that rely more on single core performance, where the i9‘s core advantage is minimized.
Clock Speeds
In addition to more cores, the i9 earns its keep by hitting higher clock speeds than the i7. This gives the i9 stronger single thread performance that directly translates to higher fps.
The Intel Core i9-12900K has a Max Turbo Boost up to 5.2 GHz and a base clock of 3.2 GHz. The Core i7-12700K isn’t too far behind with a Max Turbo of 5.0 GHz and base clock of 3.6 GHz.
But those extra 200-300 MHz the i9 achieves on boost gives it an edge, especially for games that depend heavily on CPU clock speeds. You‘ll often see this in competitive esports titles, where every frame matters.
| CPU | Base Clock | Max Turbo |
|---|---|---|
| Core i9-12900K | 3.2 GHz | 5.2 GHz |
| Core i7-12700K | 3.6 GHz | 5.0 GHz |
So in CPU bound esports games like CS:GO, you can expect around a 5-15% fps boost with the i9 versus the i7 when playing at 1080p. For example, 1080p fps on CS:GO averages around 569 fps on the i9-12900K versus 511 fps on the i7-12700K based on benchmarks.
Performance
When you look at overall real-world gaming benchmarks, the i9 consistently outperforms the i7. But the performance advantage is often modest in the range of 5-10% on average for most modern titles.
However, there are certain games where having those extra cores and clock speed headroom on the i9 pays off with more substantial gains.
For example, according to Tom‘s Hardware testing, Assassin‘s Creed Valhalla sees a 15% fps boost on the i9 versus i7 at 1080p. Red Dead Redemption 2 was 10% faster on the i9. Horizon Zero Dawn also gained 11% higher fps with the i9.
As you move to higher 1440p and 4K resolutions, the difference between the two shrinks. At 4K, the GPU becomes the limiting factor, so the CPU performance gaps between the i7 and i9 diminish.
But if you‘re trying to max out frame rates on a high refresh rate 1080p monitor, the i9 provides that extra performance cushion over the i7.
Real World Value for Gamers
Now for most gamers, the i7 delivers the best mix of gaming horsepower at a reasonable price. Honestly, the performance jump from the i7 to i9 for most games is not worth the $150-$200 price premium.
The money is better spent getting a higher tier GPU like an RTX 3080 versus 3070. That will improve performance far more than going from an i7 to i9.
However, I understand the urge to max out performance with the best of the best, especially with a high budget build. If money is no object and you want peak fps, smoothest gameplay, and maximum bragging rights, the i9 is the top choice.
Power and Thermal Demands
There is a cost though to driving the i9‘s class-leading performance – power and heat. The i9 is an extremely power hungry CPU under full load. You‘ll want a 850W+ power supply to give the i9 breathing room, especially if paired with a top-tier GPU.
The i9 also runs extremely hot when stressed. You‘ll need a high performance liquid cooler or the beefiest air cooler to tame the heat it pumps out. Don‘t even think about using a standard air cooler on the i9 unless you want thermal throttling.
Comparatively, the i7 runs much cooler and quieter with more reasonable power demands. It can easily get by with a standard 240mm AIO or mid-range air cooler. So factor in needing more robust cooling and power with the i9.
Conclusion
If gaming performance is critical and budget is flexible, the i9 reigns supreme as the fastest Intel gaming CPU money can buy. But I think most gamers are better served saving some money and going with the i7.
You‘ll get a fabulous gaming experience with the i7-12700K that can handle any game and streaming while costing $150-$200 less. Unless those last few fps are completely critical, I suggest sticking with the i7 which remains Intel‘s gaming sweet spot. But for the ultimate gaming beast, the i9 takes the crown.
