Doom

The AMD Ryzen 9 5950X paired with the AMD Radeon RX 6700 XT delivers a robust, high-refresh-rate experience in Doom, but the data reveals a clear performance hierarchy dependent on resolution and graphical preset. This combination demonstrates where the GPU becomes the limiting factor and how the processor’s exceptional multi-threading capabilities support the game’s demanding engine.

Resolution Scaling

The measured FPS data shows a steep, predictable decline as resolution increases, a pattern that firmly places the performance bottleneck on the graphics card at higher settings. At 1080p with Low settings, the combo achieves an average of 229.6 FPS. Moving to Medium reduces this to 200.9 FPS, while High drops to 172.5 FPS, and Ultra settles at 138.6 FPS. This 1080p scaling is primarily driven by the GPU’s fill rate and shading power, with the CPU having ample headroom to feed frames.

Stepping up to 1440p, the same settings show the GPU’s workload intensifying. Low settings produce 149.3 FPS, Medium 131.4 FPS, High 109.4 FPS, and Ultra falls to 90.4 FPS. The percentage drop from 1080p Low to 1440p Low is roughly 35%, indicating that even at the lowest preset, the higher pixel count is already taxing the RX 6700 XT. The transition from 1080p High to 1440p High represents a 36.6% decrease, confirming that the GPU is the primary constraint once resolution increases.

At 4K (3840x2160), the curve steepens dramatically. Low settings yield 84.1 FPS, Medium 67.5 FPS, High 59.6 FPS, and Ultra drops to 50.5 FPS. The delta between 1440p Ultra and 4K Ultra is a substantial 44.1% reduction, showcasing the immense pixel throughput required at this resolution. The gap between 4K Low and 4K Ultra is 33.6 FPS, a 40% performance swing attributable entirely to GPU load. These results indicate that for 4K gaming, the RX 6700 XT is the definitive limiting component; the Ryzen 9 5950X’s 16 cores and 32 threads are not the constraint.

How This Combo Ranks

In the broader database of tested CPU and GPU combinations, this pairing sits at rank 931 out of 1681 combos, placing it in the upper-middle tier. This percentile position reflects the balance between the high-end processor and the mid-to-high-end graphics card. The rank is more heavily influenced by the GPU’s performance class than the CPU, given that Doom is a title where frame rates scale significantly with GPU compute resources.

The Ryzen 9 5950X itself holds a 93rd percentile ranking among all CPUs, with an average benchmark score of 49062. Its nearest rivals in the CPU benchmark list include the Intel Core i5-14600K, which scores 49166 (a 0.2% delta), and the Intel Core i5-14600KF at 49367 (a 0.6% delta). This places the 5950X essentially on par with these modern mid-range Intel parts in raw average compute, despite having double the core count. The AMD EPYC 4345P scores 49595 (a 1.1% delta above), and the Intel Xeon Gold 5318H scores 48698 (a 0.7% delta below). These small deltas suggest that for Doom, the CPU’s absolute compute headroom is not the deciding factor in the final combo rank.

Conversely, the RX 6700 XT ranks at the 77th percentile among all GPUs, with an average benchmark score of 33721. Its nearest rivals show a tighter cluster: the AMD Radeon RX 6800 scores 33493 (a 0.7% delta), the AMD Radeon HD 7950 scores 34050 (a 1% delta), and the AMD Radeon RX 480 scores 34059 (a 1% delta). The NVIDIA RTX A5000 scores 33294, a 1.3% delta below. This proximity in scores indicates that the RX 6700 XT is positioned in a competitive segment where minor architectural differences dictate FPS. Given that the GPU percentile (77) is lower than the CPU percentile (93), the combo rank of 931 is dragged down by the graphics card’s relative standing, confirming that the GPU is the performance ceiling in this pairing.

GPU Role

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture using the Navi 22 chip, manufactured on a 7 nm process by TSMC. It features 12 GB of GDDR6 memory on a 192-bit bus, providing a bandwidth of 384.0 GB/s. The memory clock runs at 2000 MHz, translating to 16 Gbps effective, which is sufficient for the texture-heavy environments of Doom. The GPU’s base clock is 2321 MHz, with a game clock of 2424 MHz and a boost clock of 2581 MHz. These high clock speeds contribute to its pixel rate of 165.2 GPixel/s and texture rate of 413.0 GTexel/s.

The GPU’s FP32 performance is rated at 13.21 TFLOPS, and its shading units number 2560, with 160 TMUs and 64 ROPs. In Doom, the Ultra preset at 1440p achieves 90.4 FPS, while 4K Ultra drops to 50.5 FPS. The data shows that the GPU’s raw compute is the limiting factor at higher resolutions; the 4K Ultra result is nearly half the 1080p Ultra result of 138.6 FPS. The 12 GB VRAM capacity is not a bottleneck at these settings, as the game’s texture requirements are met without exceeding memory limits. The GPU’s end-of-life production status and its 77th percentile ranking among all GPUs indicate that while it remains capable, it is outclassed by newer or higher-tier parts in the most demanding scenarios.

FAQ

Q: What is the average FPS at 1080p with High settings?

A: The combo achieves 172.5 FPS at 1920x1080 with High settings, which is well above the 144 Hz refresh rate threshold for most monitors.

Q: How does the RX 6700 XT compare to its nearest rival, the RX 6800?

A: The RX 6700 XT has an average benchmark score of 33721, while the RX 6800 scores 33493, giving the 6700 XT a 0.7% advantage in average score. This is a negligible difference in real-world performance.

Q: Is the Ryzen 9 5950X the bottleneck in this setup?

A: No. The CPU holds a 93rd percentile ranking, and its nearest rival, the Intel Core i5-14600K, scores only 0.2% higher. The GPU’s 77th percentile ranking and the steep FPS drops at higher resolutions indicate the graphics card is the limiting component.

A: At 2560x1440 with Ultra settings, the combo achieves 90.4 FPS. At 3840x2160 with Ultra settings, it drops to 50.5 FPS, so 1440p is the optimal choice for Ultra preset gameplay.

Q: How much performance is lost when moving from 1080p Low to 4K Low?

A: The FPS drops from 229.6 at 1920x1080 Low to 84.1 at 3840x2160 Low, representing a 63.4% reduction in average frame rate.

*Q: Does the GPU’s VRAM capacity impact performance in Doom?*

A: The 12 GB of GDDR6 memory is not a limiting factor in this game, as the measured FPS scales consistently with resolution and settings without any anomalies that would suggest memory capacity issues.

CPU Role

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture (Vermeer), featuring a base clock of 3.40 GHz and a boost clock of 4.90 GHz. Its large 64 MB L3 cache and 7 nm process node give it substantial compute headroom. In Doom, the CPU’s role is to feed the GPU with prepared frames, and the data suggests it does so without becoming a bottleneck. At 1080p Low, the combo hits 229.6 FPS, a frame rate that requires high single-thread performance. The 5950X’s single-core benchmark score of 3470 in Passmark and 5450 in Cinebench R23 single-core indicate it has the necessary IPC.

The CPU’s multi-threading capabilities are also relevant. Its Cinebench R23 multi-core score of 38607 and Passmark multi-thread score of 45424 show that it can handle background tasks and the game’s engine threads simultaneously. However, the benchmark data for the CPU shows that its nearest rivals, such as the Intel Core i5-14600K, achieve nearly identical average scores. This implies that in Doom, which is not heavily multi-threaded, the 5950X’s 32 threads are underutilized. The CPU’s 93rd percentile ranking is far higher than the GPU’s 77th percentile, which is why the combo rank (931 out of 1681) is not higher.

The CPU’s memory bandwidth of 51.2 GB/s and dual-channel DDR4 support are sufficient for the game’s data streaming. The processor’s PCIe Gen 4 interface with 20 lanes provides adequate bandwidth for the GPU. In summary, the Ryzen 9 5950X provides more than enough computational power for Doom, ensuring that the RX 6700 XT is the sole limiting factor in this pairing. The measured FPS at 1080p High (172.5) and 4K Ultra (50.5) both align with the GPU’s expected scaling, confirming the processor is not holding back performance at any tested resolution.
