Doom

The AMD Ryzen 9 5950X paired with the NVIDIA GeForce RTX 4070 delivers a formidable 1080p and 1440p experience in Doom, with performance scaling that reveals a clear GPU bottleneck at higher resolutions. The data shows a system that obliterates high-refresh-rate targets at 1080p but requires settings discipline to maintain smooth framerates at 4K.

Resolution Scaling

The measured FPS data demonstrates how the workload shifts from CPU-bound to GPU-bound as resolution increases. At 1920x1080 with Low settings, the combo achieves 317.2 FPS, but this drops to 206.1 FPS at 2560x1440 and further to 108.5 FPS at 3840x2160. That represents a 34.9% performance loss from 1080p to 1440p, and a 65.8% loss from 1080p to 4K at Low settings. This steep decline indicates the RTX 4070 is the limiting factor once pixel count rises; the Ryzen 9 5950X has ample headroom at lower resolutions.

At Ultra settings, the scaling is more moderate. The system produces 191.8 FPS at 1080p, 121.4 FPS at 1440p, and 63.9 FPS at 4K. The drop from 1080p to 1440p is 36.7%, while the 4K figure is 66.7% lower than 1080p. The fact that the percentage losses are similar across Low and Ultra settings suggests that the GPU's rendering load scales predictably with resolution, and the CPU is not introducing a bottleneck even at the lowest settings where frame rates exceed 300 FPS.

The gap between Low and Ultra settings widens as resolution increases. At 1080p, the difference is 125.4 FPS (317.2 vs 191.8). At 1440p, it shrinks to 84.7 FPS (206.1 vs 121.4). At 4K, the gap narrows to 44.6 FPS (108.5 vs 63.9). This pattern confirms that at higher resolutions, the GPU is saturated regardless of settings, while at 1080p, the CPU can feed frames fast enough to expose the full performance range of the graphics card.

CPU Role

The Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture with a base clock of 3.40 GHz and a boost clock of 4.90 GHz. Its benchmark results show exceptional multi-threaded capability, with a Cinebench R23 multicore score of 38607 and a Passmark multithread score of 45424. The single-thread performance is also strong, with a Cinebench R23 single-core score of 5450, which is critical for a game like Doom that benefits from high per-core throughput.

In this combo, the CPU's role is to ensure that frame delivery never becomes the bottleneck. The data supports this: at 1080p Low, the system hits 317.2 FPS, a figure that many CPUs would struggle to feed. The 3DMark single-thread score of 944 and the 2-thread score of 1856 indicate that the processor has the raw speed to handle the game's primary thread requirements. The CPU's 64 MB of L3 cache also helps maintain high memory bandwidth for game assets.

The CPU's 105 W TDP and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are adequate for this workload. The processor's percentile rank of 93 among all CPUs, with an average benchmark score of 49062, places it within 0.2% of the Intel Core i5-14600K (49166) and 0.6% behind the Core i5-14600KF (49367). This proximity in average score suggests that for Doom, the 5950X's multi-threaded advantage is not fully utilized, but its single-thread performance is sufficient to avoid limiting the RTX 4070.

GPU Role

The NVIDIA GeForce RTX 4070, built on the Ada Lovelace architecture with 5 nm process, features 12 GB of GDDR6X memory on a 192-bit bus, delivering 504.2 GB/s of bandwidth. Its boost clock of 2475 MHz and 5888 shading units provide substantial raw compute power, with an FP32 rating of 29.15 TFLOPS. The GPU's benchmark results, including a Passmark G3D score of 26927 and a 3DMark Steel Nomad DX12 score of 3854, reflect its position in the market.

The RTX 4070's 12 GB VRAM is the likely constraint at 4K Ultra. The measured 63.9 FPS at 3840x2160 Ultra is the lowest result in the dataset, and the 33.9% drop from High (80.6 FPS) to Ultra (63.9 FPS) at 4K suggests that the Ultra preset's additional texture and effect demands, combined with the higher pixel count, push the GPU to its limits. At 1080p, the GPU has more headroom, with Ultra producing 191.8 FPS, which is still well above the 144 Hz threshold for most high-refresh monitors.

The GPU's 200 W TDP and 550 W suggested PSU are modest for its performance class. Its percentile rank of 81 among all GPUs, with an average benchmark score of 37283, places it near the AMD Radeon RX Vega 56 (37507, 0.6% faster) and 1.9% behind the NVIDIA GeForce MX570 A (38008). However, in Doom specifically, the RTX 4070's performance is strong enough to deliver playable framerates at all tested settings, provided the resolution is managed appropriately.

How This Combo Ranks

The combo ranks 438 out of 1681 tested combinations, placing it in the top 26% of all systems tested for Doom. This ranking reflects the balance between the 16-core CPU and the RTX 4070. The CPU's 93rd percentile standing among all CPUs, combined with the GPU's 81st percentile, creates a system that is well-suited for high-refresh 1440p gaming but not optimized for 4K Ultra.

The rank of 438 suggests that there are 437 other combos that achieve higher average FPS in Doom. Given that the CPU is not the bottleneck at 1080p (317.2 FPS at Low), the ranking is likely determined by the GPU's performance at higher resolutions. Systems with more powerful GPUs, such as those with higher VRAM or more shading units, would naturally rank higher at 4K. The RTX 4070's 12 GB VRAM may also be a limiting factor compared to GPUs with larger memory pools, especially at Ultra settings where texture sizes are maximal.

FAQ

Measured FPS Breakdown

At 1920x1080, the system delivers its highest framerates. With Low settings, the average FPS is 317.2. Moving to Medium, it drops to 273.8, a 13.7% reduction. High settings produce 229.9 FPS, and Ultra yields 191.8 FPS. All of these results are well above the 144 Hz refresh rate common in gaming monitors, making this resolution ideal for competitive play.

At 2560x1440, the performance remains strong but shows the GPU beginning to work harder. Low settings average 206.1 FPS, Medium produces 176.2 FPS, High delivers 146.7 FPS, and Ultra drops to 121.4 FPS. The transition from Low to Ultra represents a 41.1% reduction in FPS, which is more pronounced than at 1080p, indicating the GPU is becoming the limiting factor.

At 3840x2160, the GPU is clearly the primary constraint. Low settings average 108.5 FPS, Medium produces 95.6 FPS, High delivers 80.6 FPS, and Ultra drops to 63.9 FPS. The gap between Low and Ultra is 44.6 FPS, and even the highest setting at Low does not reach the 120 FPS mark. For a consistent 60+ FPS experience, Medium or High settings are the practical choices at 4K.
