Doom

The AMD Ryzen 5 7600X paired with the AMD Radeon RX 7700 XT delivers a decisive performance profile in Doom, one that shifts from GPU-bound at 4K to increasingly CPU-reliant as resolution drops. The measured frame rates reveal a system capable of high refresh-rate gaming at 1440p, while the 4K results indicate where the graphics card becomes the primary constraint.

Resolution Scaling

The frame rate deltas across the three tested resolutions clearly define the bottleneck hierarchy. At 1080p with Low settings, the combo produces 263.9 FPS. Moving to 1440p Low drops this to 172.7 FPS, a reduction of 91.2 FPS, or roughly 34.5% lower. Scaling further to 4K Low yields 93.5 FPS, which is 45.8% below the 1440p figure and 64.6% below the 1080p result.

This scaling pattern indicates that at 1080p, the system is not fully GPU-limited; the CPU is capable of feeding the graphics card enough data to reach very high frame rates. The substantial drop to 1440p suggests the GPU is starting to hit its limits, and the further decline at 4K confirms a strong GPU constraint. For the Ultra preset, the trajectory is similar but compressed: 160.8 FPS at 1080p, 104.1 FPS at 1440p (a 35.3% drop), and 55.4 FPS at 4K (a 46.8% drop from 1440p). The data shows that while the CPU allows for excellent 1080p performance, the RX 7700 XT is the limiting factor for 4K Ultra, where the frame rate falls below 60 FPS.

GPU Role

The Radeon RX 7700 XT is built on the RDNA 3.0 architecture with a Navi 32 chip, featuring a boost clock of 2544 MHz and a game clock of 2171 MHz. Its memory subsystem comprises 12 GB of GDDR6 on a 192-bit bus, providing a bandwidth of 432.0 GB/s. These specifications directly influence the observed 4K performance. The 12 GB frame buffer is sufficient for Doom at 4K, but the 432.0 GB/s bandwidth becomes a factor when pushing high pixel counts with Ultra settings.

The benchmark data shows the GPU’s compute potential: a PassMark G3D score of 22547 and a 3DMark Steel Nomad DX12 score of 3316. This places the GPU in the 73rd percentile of all GPUs, with an average benchmark score of 30097. The closest rival, the NVIDIA GeForce RTX 5060, scores 30109, a delta of 0% — indicating they are statistically tied in aggregate benchmarks. The RX 7700 XT’s 35.17 TFLOPS of FP32 compute is substantial, but the 4K Ultra result of 55.4 FPS shows that raw compute is not the sole determinant; memory bandwidth and pixel throughput (244.2 GPixel/s) also play critical roles. The drop from High (68.5 FPS) to Ultra (55.4 FPS) at 4K, a 19.1% reduction, highlights the cost of the extra shading work and texture detail in the higher preset.

CPU Role

The AMD Ryzen 5 7600X is a 6-core, 12-thread processor based on the Zen 4 architecture, with a base clock of 4.70 GHz and a boost clock of 5.30 GHz. Its strong single-thread performance is evident in the Cinebench R23 single-core score of 3406 and the 3DMark single-thread score of 1060. This processor’s capability is a key reason why 1080p frame rates can reach such high values; the CPU is not a bottleneck at that resolution.

The CPU’s multi-threaded performance is also robust, with a Cinebench R23 multi-core score of 24128 and a PassMark multi-thread score of 28390. However, the data suggests that Doom does not heavily tax all 12 threads. The scaling from 1080p to 1440p shows a larger drop than would be expected if the CPU were the primary limiter at 1080p; the GPU is being tasked with more work. The CPU’s percentile ranking (83rd) versus the GPU’s (73rd) confirms that the processor is the stronger component relative to its peers. The 32 MB of shared L3 cache and 83.2 GB/s of memory bandwidth provide sufficient data to keep the GPU fed, but the measured FPS curves indicate that at 1440p and above, the RX 7700 XT’s rendering throughput is the defining factor.

How This Combo Ranks

In the database of tested combinations for Doom, this specific pairing of the Ryzen 5 7600X and RX 7700 XT achieves a combo rank of 726 out of 1681 combos. This places it in the upper-middle tier of all tested systems, which is a strong result given the balance between the CPU and GPU. The rank is a holistic measure that accounts for performance across all resolutions and settings tested.

The CPU’s nearest rivals in aggregate benchmarks include the AMD Ryzen 7 PRO 6850U (deltaPct 0%) and the AMD Ryzen 7 7735U (deltaPct -0.1%). The GPU’s nearest rival is the NVIDIA GeForce RTX 5060 (deltaPct 0%). The fact that the CPU ranks higher (83rd percentile) than the GPU (73rd percentile) suggests that the combo’s overall rank is slightly held back by the GPU’s relative position. A more powerful GPU would likely push this combo higher, but the current pairing provides a consistent experience without a significant CPU bottleneck.

Measured FPS Breakdown

The measured FPS data provides a complete picture across all resolution and settings combinations. At 1920x1080, the results are:

• Low: 263.9 FPS
• Medium: 229.2 FPS
• High: 192.7 FPS
• Ultra: 160.8 FPS

The spread from Low to Ultra is 103.1 FPS, showing that the CPU can maintain high throughput, but the GPU’s rendering load increases with settings. At 2560x1440, the results are:

• Low: 172.7 FPS
• Medium: 145.4 FPS
• High: 124.8 FPS
• Ultra: 104.1 FPS

The 1440p data shows a tighter spread (68.6 FPS) as the GPU becomes more of a limiting factor. The High setting at 1440p still exceeds 120 FPS, which is ideal for high-refresh-rate monitors. At 3840x2160, the results are:

• Low: 93.5 FPS
• Medium: 79.7 FPS
• High: 68.5 FPS
• Ultra: 55.4 FPS

The 4K results show a clear GPU limit. Even on Low settings, the frame rate drops below 100 FPS, and Ultra settings fall below 60 FPS, making 4K Ultra a less viable option for smooth gameplay on this combo. The data indicates that 1440p is the sweet spot for this pairing, offering high frame rates with headroom for Ultra settings, while 4K requires reduced settings to maintain playable performance. The consistent pattern across all settings shows a GPU that scales predictably with resolution, and a CPU that provides a solid foundation for high-FPS gaming at lower resolutions.
