Doom

The AMD Ryzen 7 7800X3D and NVIDIA GeForce RTX 5090 D combination delivers exceptional performance in Doom, with measured frame rates that place it in the top percentile of all tested configurations. The data reveals a system that is overwhelmingly GPU-limited at higher resolutions but shows signs of CPU influence at the lowest settings, particularly at 1080p. This analysis breaks down the measured FPS across resolutions and settings, examines the role each component plays, and provides actionable insights based strictly on the benchmark data.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 7800X3D is an 8-core, 16-thread processor based on the Zen 4 Raphael architecture, built on a 5 nm process at TSMC. It operates with a base clock of 4.20 GHz and a boost clock of 5.00 GHz, with a 120 W TDP. The processor features a substantial 96 MB of shared L3 cache, which is a defining characteristic of the X3D line and often beneficial in gaming workloads. Its 3DMark scores show strong scaling: 1,887 in the 2-thread test, 3,684 in 4-thread, 6,539 in 8-thread, and 7,980 in the 16-thread test, indicating that performance gains from additional threads flatten out quickly after 8 threads. This suggests that Doom, a game released in 2016, does not fully utilize the 16 threads available.

In the context of Doom’s results, the CPU’s role appears to be providing a high single-thread performance ceiling. The single-thread 3DMark score is 959, and Cinebench R23 single-core is 1,713 points. These figures, combined with the large L3 cache, help ensure that the CPU does not become a bottleneck in most scenarios. The processor’s percentile ranking versus all CPUs is 83, placing it above the majority of processors in the database. Its nearest rivals, such as the AMD Ryzen 7 8700G and Intel Core i7-13650HX, have nearly identical average benchmark scores (33,089 vs. 33,079), indicating that this CPU is at the top of its performance class, though not uniquely so.

The data shows that at 1080p with Low settings, the system achieves 394 FPS, which is the highest measured average across all configurations. This high frame rate suggests that the CPU is capable of feeding the GPU with enough data to maintain extreme performance. However, the difference between 1080p Low (394 FPS) and 1080p High (354 FPS) is 40 FPS, which is a 10% drop. This drop is likely due to increased GPU workload, but the CPU is still keeping pace. The fact that the 7800X3D has a boost clock of 5.00 GHz and 16 threads, with a PassMark multi-thread score of 34,293, supports the idea that it has ample headroom for this title. The Cinebench R23 multi-core score of 16,817 further confirms its capability in threaded workloads, but Doom’s engine appears to rely more on the strong single-core performance and cache efficiency.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 5090 D is a flagship graphics card based on the Blackwell 2.0 architecture, featuring the GB202 chip built on a 5 nm process. It boasts 32 GB of GDDR7 memory on a 512-bit bus, providing a memory bandwidth of 1.79 TB/s. The GPU has a base clock of 2,017 MHz and a boost clock of 2,407 MHz, with a memory clock of 1,750 MHz (28 Gbps effective). It contains 21,760 shading units, 680 texture mapping units, and 176 ROPs, along with 170 RT cores and 680 tensor cores. The card’s pixel rate is 423.6 GPixel/s, and its texture rate is 1,636.8 GTexel/s, with FP32 performance at 104.8 TFLOPS.

In Doom, the GPU’s role is dominant, as evidenced by the frame rate scaling across resolutions. At 4K Ultra, the system averages 102 FPS, while at 4K Low it averages 170 FPS. This 68 FPS difference (40% increase) shows that the GPU is the primary limiter when settings are increased. The RTX 5090 D’s benchmarks reflect its high-end positioning, with a PassMark G3D score of 44,065 and a percentile ranking of 92 versus all GPUs. Its nearest rivals in the database include the AMD Radeon RX 6850M XT (average score 78,940, delta -1.6%) and the NVIDIA Tesla P100 PCIe 16 GB (average score 79,605, delta -2.4%), which are significantly lower in performance, indicating the 5090 D sits in an elite tier.

The GPU’s 32 GB of VRAM is more than sufficient for Doom, which is not a demanding title by modern standards. The high memory bandwidth of 1.79 TB/s ensures that texture streaming and high-resolution rendering are not hindered. The data shows that at 4K High, the system achieves 125 FPS, which is a solid playable frame rate for a fast-paced FPS. The GPU’s boost clock of 2,407 MHz, combined with its massive shading unit count, allows it to handle the Vulkan-based Doom engine efficiently. The 3DMark Steel Nomad DX12 score of 14,326 further validates its raw compute power, which translates into the high frame rates seen in the measured data.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

Examining the measured FPS across resolutions reveals a clear pattern of GPU limitation. At High settings, the average FPS drops from 354 at 1080p to 231 at 1440p, and then to 125 at 4K. This represents a 35% drop from 1080p to 1440p, and a further 46% drop from 1440p to 4K. The scaling is consistent with the GPU being the bottleneck, as the workload increases with pixel count.

At Low settings, the drop is more pronounced in relative terms: 394 FPS at 1080p, 314 FPS at 1440p (a 20% drop), and 170 FPS at 4K (a 46% drop from 1440p). The larger drop from 1440p to 4K at Low settings (46%) compared to High settings (46% as well) suggests that even at Low settings, the GPU is still the limiting factor at 4K. However, the smaller drop from 1080p to 1440p at Low (20%) compared to High (35%) indicates that at 1080p Low, the CPU may be starting to become a co-limiting factor, as the frame rate is extremely high (394 FPS), pushing the limits of what the processor can deliver.

The data shows that the RTX 5090 D is the dominant component in this pairing. At 4K Ultra, the system averages 102 FPS, which is a 74% reduction from 1080p Low (394 FPS). This is a massive drop that highlights the GPU’s workload at higher resolutions. The fact that the 7800X3D’s strong single-thread performance (3DMark single-thread score of 959) is able to support 394 FPS at 1080p Low suggests that the CPU is not a significant bottleneck until frame rates approach 400 FPS. The measured FPS at 1080p Medium (375 FPS) and 1080p High (354 FPS) further confirm that the CPU has headroom, as the GPU is still the main limiter at these settings.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the best experience depends on the user’s display refresh rate and resolution. At 1080p, even Ultra settings provide an average of 292 FPS, which is far above any standard refresh rate (e.g., 144 Hz, 240 Hz). The data shows that Low settings at 1080p yield 394 FPS, but the visual quality trade-off may not be worth the extra 102 FPS over Ultra. For most users at 1080p, High settings (354 FPS) offer a good balance of visual fidelity and performance, as the frame rate is still exceptionally high.

At 1440p, High settings average 231 FPS, which is sufficient for high-refresh-rate monitors (e.g., 240 Hz). Ultra settings at 1440p average 189 FPS, which is still very playable and provides the best visual quality. The data shows that Medium settings at 1440p average 273 FPS, with a minimum of 232 FPS, which could be a good choice for those with 240 Hz displays who want a safety margin. Low settings at 1440p (314 FPS) are unnecessary unless the user has a 360 Hz or higher refresh rate monitor.

At 4K, the situation changes. Ultra settings average 102 FPS, which is above the 60 FPS threshold but below 144 Hz. High settings average 125 FPS, Medium settings average 148 FPS, and Low settings average 170 FPS. For a 4K 120 Hz display, High settings (125 FPS) would be the best choice, as it provides a smooth experience with good visuals. For a 4K 144 Hz display, Medium settings (148 FPS) would be more appropriate, though the visual quality is slightly reduced. Low settings at 4K (170 FPS) offer the highest frame rate but may look noticeably worse. The data suggests that at 4K, the user should choose between High and Medium settings depending on their refresh rate, as Ultra (102 FPS) is only suitable for 60 Hz displays.
