We benchmark the best processors from Intel and AMD to determine the ultimate CPU for high-resolution gaming in 2023.
While 4K gaming is primarily GPU-bound, your processor still plays a crucial role in delivering smooth, stutter-free performance. At ultra-high resolutions, you need a CPU that can:
We've tested the latest processors from Intel and AMD across a range of demanding 4K games to identify the best options for different budgets and use cases.
All benchmarks were conducted using the following configuration:
All games were tested at 4K resolution with max settings (including ray tracing where available). We measured average FPS, 1% lows, and frame time consistency across multiple runs.
Processor | Cores/Threads | Boost Clock | Cache | TDP | Price |
---|---|---|---|---|---|
Intel Core i9-13900K | 24 (8P+16E)/32 | 5.8 GHz | 36MB L3 | 125W | $589 |
AMD Ryzen 9 7950X3D | 16/32 | 5.7 GHz | 144MB (3D V-Cache) | 120W | $699 |
Intel Core i7-13700K | 16 (8P+8E)/24 | 5.4 GHz | 30MB L3 | 125W | $409 |
AMD Ryzen 7 7800X3D | 8/16 | 5.0 GHz | 104MB (3D V-Cache) | 120W | $449 |
AMD Ryzen 9 7950X | 16/32 | 5.7 GHz | 80MB | 170W | $599 |
While the differences in average FPS are relatively small at 4K (as expected in GPU-bound scenarios), the AMD 3D V-Cache processors show superior frame consistency, particularly in open-world games like Microsoft Flight Simulator and Red Dead Redemption 2.
The 7950X3D combines the best of both worlds - high clock speeds for gaming and 16 cores for productivity. Its 3D V-Cache delivers exceptional frame consistency at 4K while leaving headroom for background tasks.
View Pricing →Nearly matches the gaming performance of the 7950X3D at a lower price point. The perfect choice if you're focused purely on gaming and don't need the extra cores.
View Pricing →While slightly behind in pure gaming, the 13900K dominates in productivity workloads. Ideal if you stream, edit videos, or work with 3D rendering alongside gaming.
View Pricing →At 4K, CPUs typically operate below their maximum power draw since the GPU is doing most of the work. However, efficiency still matters for system thermals and electricity costs.
Processor | Power Draw (Gaming) | Temperature (Gaming) | Performance per Watt |
---|---|---|---|
Ryzen 7 7800X3D | 85W | 68°C | 1.6 FPS/W |
Ryzen 9 7950X3D | 105W | 72°C | 1.32 FPS/W |
Core i9-13900K | 125W | 78°C | 1.14 FPS/W |
Core i7-13700K | 115W | 75°C | 1.17 FPS/W |
Ryzen 9 7950X | 120W | 74°C | 1.11 FPS/W |
The Ryzen 7 7800X3D stands out as the most efficient option, delivering excellent performance while running cool and quiet. Intel's processors consume significantly more power for similar gaming performance at 4K.
When building a 4K gaming system, it's wise to consider how your CPU will handle future GPU upgrades:
For pure 4K gaming performance, AMD's 3D V-Cache processors currently hold the crown. The Ryzen 9 7950X3D offers the best combination of gaming performance and multi-threaded capability, while the Ryzen 7 7800X3D provides nearly identical gaming performance at a lower price point.
Intel's Core i9-13900K remains a compelling option for those who prioritize content creation alongside gaming, though it falls slightly behind in frame consistency and power efficiency.
