Doom

Resolution Scaling

The measured frame rates for Doom with the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 4070 Ti SUPER reveal a clear scaling pattern as resolution increases. At 1080p with High settings, the combo produces 276.2 FPS. Moving to 1440p drops that to 173.3 FPS, a reduction of roughly 37%. The step to 4K brings the average down to 96.7 FPS, which is another 44% decline from the 1440p figure. This trajectory indicates that the rendering load is scaling heavily with pixel count, which is typical for a game of this era that is not particularly demanding on modern hardware.

The gap between Low and Ultra settings widens dramatically at higher resolutions. At 1080p, the spread from Low (372.6 FPS) to Ultra (220.4 FPS) is about 152 FPS. At 1440p, that spread narrows to 99 FPS (241.1 down to 142.1). At 4K, the difference shrinks further to 53.7 FPS (129.8 down to 76.1). This compression suggests that at 4K, the GPU becomes the limiting factor more decisively, as the per-pixel cost of Ultra settings grows disproportionately. The data shows that resolution scaling is not linear; the percentage loss from 1440p to 4K is steeper than from 1080p to 1440p across all settings, indicating the GPU is approaching its throughput ceiling.

Interestingly, the Low preset at 4K still achieves 129.8 FPS, which is well above the 76.1 FPS of Ultra. This implies that the game's visual complexity at Ultra imposes a significant shader and fill-rate burden. The benchmark results indicate that the CPU, with its 12 cores and 24 threads based on the Zen 4 architecture, is not the primary constraint at 4K; instead, the GPU's pixel and texture processing rates—250.6 GPixel/s and 689.0 GTexel/s respectively—dictate the upper bound. At 1080p, the high frame rates (up to 372.6 FPS on Low) suggest that the CPU is still keeping pace, but the GPU is already working hard to maintain those numbers.

GPU Role

The RTX 4070 Ti SUPER operates with a base clock of 2340 MHz and a boost clock of 2610 MHz, built on the Ada Lovelace architecture with 8448 shading units. Its 16 GB of GDDR6X memory on a 256-bit bus provides 672.3 GB/s of bandwidth. In this game, the memory capacity is more than sufficient, but the bandwidth becomes relevant at 4K Ultra where the frame rate falls to 76.1 FPS. The data does not show VRAM exhaustion symptoms, such as sudden frame drops or stuttering, which would appear if the 16 GB buffer were inadequate. Instead, the performance curve is smooth, indicating that the GPU's compute and memory subsystems are working in balance.

The GPU's FP32 throughput of 44.10 TFLOPS is the raw compute resource that Doom's Vulkan-based renderer can exploit. At 1080p Medium, the combo hits 322.3 FPS, which is 46% higher than High at the same resolution. This suggests that the game's Medium preset reduces certain shading workloads enough to allow the GPU to push more frames. The RTX 4070 Ti SUPER's 66 RT cores and 264 tensor cores are not directly tested by this game's traditional rasterization path, but they do contribute to the overall architecture's efficiency. The benchmark scores for this GPU place it at the 86th percentile among all GPUs, with an average benchmark score of 48704. Its nearest rivals in synthetic tests include the NVIDIA CMP 50HX, which scores slightly higher at 49071, a delta of -0.7%, and the RTX A2000 at 47915, which is 1.6% lower.

The clock behavior is also telling. With a boost clock of 2610 MHz, the GPU sustains high frequencies under load, which is essential for maintaining the 276.2 FPS seen at 1080p High. The power draw of 285 W suggests that the card is not thermally constrained in this scenario, allowing consistent performance. The data shows that the GPU is the dominant factor in this combo's results, as evidenced by the resolution scaling analysis. The CPU's role is to feed the GPU with draw calls, and with a Cinebench R23 multi-core score of 43695 and a single-core score of 6168, it is more than capable of doing so without becoming a bottleneck.

FAQ

Q: What is the maximum average FPS this combo achieves in Doom?

A: The Ryzen 9 7900X is at the 93rd percentile among all CPUs, with an average benchmark score of 50556. This high standing supports the observation that it does not bottleneck the GPU, allowing the GPU to be the limiting factor at higher resolutions.

Q: Is the frame rate at 4K High playable?

A: Yes, the 4K High average of 96.7 FPS is well above the 60 FPS threshold for smooth gameplay, and even 4K Ultra at 76.1 FPS is playable.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution and desired frame rate. For 4K, the High preset provides the best balance, delivering 96.7 FPS. This is significantly higher than Ultra's 76.1 FPS, and the visual difference between High and Ultra is often marginal in fast-paced FPS games like Doom. The Medium preset at 4K offers 115.7 FPS, which is even smoother, but High is recommended for a better visual experience while staying above 90 FPS.

At 1440p, the High preset at 173.3 FPS is the sweet spot. It offers a substantial visual upgrade over Medium (209.3 FPS) while still maintaining a frame rate that exceeds most high-refresh-rate monitors. The Ultra preset at 142.1 FPS is also viable, but the 31 FPS drop from High may not be worth the extra visual fidelity in a game that relies on fast motion. For competitive play, the Low preset at 241.1 FPS would be preferred, but for general use, High is recommended.

At 1080p, the data shows that even Ultra achieves 220.4 FPS, which is excellent. However, the Medium preset at 322.3 FPS is only slightly lower in visual quality but provides a 46% increase in frame rate. For gamers with a 240 Hz monitor, Medium is the recommended choice, as it fully saturates the display's refresh rate. The High preset at 276.2 FPS also works, but Medium offers a safer margin above 300 FPS. The Low preset at 372.6 FPS is unnecessary unless chasing maximum FPS for esports.

How This Combo Ranks

The combination of the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 4070 Ti SUPER holds a rank of 182 out of 1681 tested combos in Doom. This places it in the top 11% of all configurations, which is a strong showing given the game's age and the hardware's capabilities. The CPU's percentile of 93 and the GPU's percentile of 86 both contribute to this high ranking, but the GPU's synthetic score of 48704 is closer to its rivals than the CPU's score is to its peers. The CPU's nearest rival, the Intel Core Ultra 5 235, scores 50598, a delta of -0.1%, indicating near-identical performance. The GPU's closest rival, the NVIDIA CMP 50HX, scores 49071, a delta of -0.7%.

This ranking suggests that while the combo is not at the absolute top, it is well above average. The 182nd position out of 1681 means there are 181 combos that perform better, likely featuring higher-tier GPUs such as the RTX 4090 or newer architectures. The data shows that this combo is within striking distance of the top tier, as the frame rates at 1080p are already very high. The ranking also reflects the balance between CPU and GPU; neither component is disproportionately weak, allowing the combo to perform consistently across all resolutions.

Measured FPS Breakdown

At 1920x1080, the combo delivers the following average FPS: Low 372.6, Medium 322.3, High 276.2, and Ultra 220.4. The progression from Low to Ultra shows a steady decline, with Ultra being 40.8% slower than Low. At 2560x1440, the averages are Low 241.1, Medium 209.3, High 173.3, and Ultra 142.1. The drop from Low to Ultra at 1440p is 41.1%, similar to 1080p, indicating consistent scaling. At 3840x2160, the averages are Low 129.8, Medium 115.7, High 96.7, and Ultra 76.1. The drop from Low to Ultra at 4K is 41.4%, which is nearly identical to the other resolutions.

The resolution scaling from 1080p to 1440p at High settings shows a 37.3% decrease (276.2 to 173.3). From 1440p to 4K at High, the decrease is 44.2% (173.3 to 96.7). This shows that the 4K leap is more punishing than the 1440p leap. At Low settings, the 1080p to 1440p drop is 35.3% (372.6 to 241.1), and the 1440p to 4K drop is 46.2% (241.1 to 129.8). At Ultra settings, the 1080p to 1440p drop is 35.5% (220.4 to 142.1), and the 1440p to 4K drop is 46.4% (142.1 to 76.1). These percentages demonstrate that the GPU's workload scales more steeply at 4K, reinforcing the conclusion that the GPU is the limiting factor at that resolution.
