Doom

The AMD Ryzen 7 7700X and AMD Radeon RX 7900 XTX combination ranks 261st out of 1,681 tested combos in Doom, placing it in the top 15.5% of all systems. This is a strong result, but the ranking reveals that while the hardware is high-end, the game’s aging engine and the specific balance of CPU and GPU here prevent it from reaching the absolute top tier. The data indicates a system that delivers exceptional frame rates across all resolutions, with the primary bottleneck shifting from the GPU at 4K to the CPU at 1080p.

How This Combo Ranks

The combo’s rank of 261 out of 1,681 is impressive, but it is not a top-50 finish. The data suggests that this pairing is overkill for Doom at 1080p, where the CPU becomes the limiting factor, yet it is still capable of delivering a very high refresh rate experience. The position is driven by the GPU’s strong raw performance, as evidenced by its 85th percentile ranking among all GPUs, and the CPU’s 89th percentile ranking. The delta between the two components is small, but the game’s relatively low thread demands mean the CPU’s eight cores are not fully utilized. Consequently, the combo’s overall position is determined more by the GPU’s ability to push high frame rates at higher resolutions, where it shines, rather than at 1080p where the CPU’s single-thread performance is adequate but not exceptional.

GPU Role

The Radeon RX 7900 XTX is the dominant component in this pairing for Doom. Its 24 GB of GDDR6 memory on a 384-bit bus provides 960.0 GB/s of bandwidth, which is more than sufficient for the game’s textures. The GPU clock speeds are notable: a base clock of 1929 MHz, a game clock of 2365 MHz, and a boost clock of 2498 MHz. The boost clock is the key figure, as it indicates the card’s sustained performance headroom under load. The data shows that the GPU’s 61.39 TFLOPS of FP32 compute is the primary driver of the high frame rates observed. For instance, at 4K Ultra, the system still manages 79.6 FPS, which reflects the GPU’s raw power. The GPU’s 6144 shading units and 192 ROPs are also critical, as they directly impact pixel throughput. The card’s percentile rank of 85 against all GPUs is reflected in these results, but the nearestRivals data shows it is only 0.8% ahead of the NVIDIA GeForce RTX 4090 Mobile in average benchmark score, and 1.6% ahead of the NVIDIA Quadro M6000. This indicates a tightly contested performance tier, yet the RX 7900 XTX consistently delivers higher FPS in this game’s measured rows.

Resolution Scaling

The FPS scaling from 1080p to 4K clearly illustrates the shift in the limiting component. At 1080p Low, the system achieves 361.9 FPS, but at 4K Low, it drops to 124.7 FPS, a 65.5% reduction. This dramatic drop indicates that at 1080p, the CPU is the primary bottleneck, as the GPU is not being fully utilized. The scaling is more gradual at higher settings: from 1080p High (266.1 FPS) to 4K High (95 FPS) is a 64.3% decrease, and from 1080p Ultra (217.1 FPS) to 4K Ultra (79.6 FPS) is a 63.3% decrease. The consistency of this drop across settings suggests that the GPU’s workload scales predictably with resolution. At 1440p, the frame rates are still very high, with 233.1 FPS on Low and 172.8 FPS on High, indicating a balanced system where neither component is severely limiting. The data points to the GPU becoming the sole bottleneck at 4K, where the CPU’s role diminishes, but the GPU still delivers playable, high-refresh-rate results even at Ultra settings.

FAQ

Q: What is the best resolution for this combo to maintain above 200 FPS?

A: At 1440p, the system achieves over 200 FPS on Low (233.1) and Medium (203.6) settings, making it the sweet spot for high refresh rate monitors without sacrificing image quality.

Q: How does the RX 7900 XTX compare to the RTX 4090 Mobile in average benchmark score?

A: The RX 7900 XTX has an average benchmark score of 44,019, which is 0.8% higher than the NVIDIA GeForce RTX 4090 Mobile’s score of 43,667, according to the nearestRivals data.

Q: Is the Ryzen 7 7700X a bottleneck at 1080p?

A: Yes, the data suggests so. At 1080p Low, the system hits 361.9 FPS, but this is significantly lower than what the GPU could theoretically produce, indicating the CPU’s single-thread performance is the limiting factor.

Q: What is the highest FPS recorded across all measured settings?

A: The highest average FPS is 361.9, achieved at 1920x1080 resolution with Low settings.

Q: Does the GPU’s 24 GB VRAM provide any advantage in Doom?

A: The 24 GB VRAM is far more than Doom requires, but the associated 960.0 GB/s bandwidth ensures that texture streaming and high-resolution rendering are never memory-bound, as seen in the consistent performance at 4K.

Q: How does the combo rank percentile-wise for the CPU and GPU individually?

A: The CPU ranks in the 89th percentile among all CPUs, while the GPU ranks in the 85th percentile among all GPUs, indicating both are high-end components.

CPU Role

The AMD Ryzen 7 7700X is a Zen 4 architecture processor with 8 cores and 16 threads, operating at a base clock of 4.50 GHz and a boost clock of 5.40 GHz. Its 32 MB of shared L3 cache and 1 MB per-core L2 cache are crucial for gaming performance. The CPU’s single-thread performance is its most important attribute for Doom, a game that is not heavily multi-threaded. The Cinebench R23 single-core score of 4,281 and Geekbench single-core score of 2,985 are strong, but the data shows that at 1080p, the CPU’s 4,190 Passmark single-thread score is the limiting factor. The CPU’s multi-thread capabilities, such as a Cinebench R23 multi-core score of 30,325, are largely irrelevant here. The CPU’s 89th percentile ranking is driven by these synthetic benchmarks, but in Doom, the frame rates at 1080p are lower than the GPU’s potential, confirming the CPU bottleneck. The nearestRivals data places the 7700X just 0.4% ahead of the Intel Core i5-13500 and 0.5% ahead of the Intel Core i7-12800HX, but 0.8% behind the Intel Core Ultra 7 165H, showing a very competitive mid-range-to-high-end tier.

Settings Recommendations

The measured data shows that the Ultra preset is the best choice for visual fidelity without compromising the experience, provided the monitor supports high refresh rates. At 4K Ultra, the system still delivers 79.6 FPS, which is above the 60 FPS threshold for smooth gameplay. However, for competitive play, the High preset is the recommended balance. At 1440p High, the system hits 172.8 FPS, which is excellent for fast-paced action, and at 1080p High, it reaches 266.1 FPS, ensuring no frame rate drops on high-refresh displays. The Low preset offers the highest frame rates, but the visual sacrifice is not necessary given the hardware. The Medium preset is a middle ground, but the data shows that the jump from Medium to High at 1440p costs only 30.8 FPS (from 203.6 to 172.8), while providing a significant visual improvement. Therefore, High at 1440p is the optimal setting for most users, as it maintains a very high frame rate while keeping the game looking sharp.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. Low settings produce 361.9 FPS, Medium 316.4 FPS, High 266.1 FPS, and Ultra 217.1 FPS. The scaling from Low to Ultra shows a 144.8 FPS drop, which is a 40% reduction, indicating that the CPU is the limiting factor at this resolution, as the GPU is not fully taxed.

At 2560x1440, the frame rates remain very high. Low settings yield 233.1 FPS, Medium 203.6 FPS, High 172.8 FPS, and Ultra 144.5 FPS. The drop from Low to Ultra is 88.6 FPS, or 38%, which is a smaller percentage than at 1080p, suggesting a more balanced workload between CPU and GPU.

At 3840x2160, the GPU becomes the clear limiting component. Low settings produce 124.7 FPS, Medium 108.9 FPS, High 95 FPS, and Ultra 79.6 FPS. The drop from Low to Ultra is 45.1 FPS, or 36.2%, which is the smallest percentage drop across resolutions. This indicates that the GPU’s raw compute power is the primary determinant of performance at 4K, and the CPU’s role is diminished. The data conclusively shows that this combo is capable of delivering a smooth experience at 4K on High settings, and an exceptional one at 1440p on Ultra, with the CPU bottleneck only appearing at 1080p.
