Doom

The AMD Ryzen 7 5800X3D pairs an 8-core, 16-thread Zen 3 design with a 96 MB shared L3 cache, a configuration that historically excels in gaming workloads. Its 3.40 GHz base and 4.50 GHz boost clocks are modest by modern standards, yet the large cache compensates by reducing memory latency. This CPU sits at the 83rd percentile among all tested processors, with an average benchmark score of 26574. The data reveals a tight cluster of rivals: the AMD EPYC 8024P scores 26555 (0.1% ahead), the Intel Core i9-11900K scores 26546 (0.1% ahead), the AMD Ryzen 5 7600 scores 26617 (0.2% behind), and the Intel Core i9-12900HK scores 26672 (0.4% behind). This suggests that in this game, the 5800X3D’s cache-heavy design performs on par with, or slightly below, these alternatives, meaning the CPU is unlikely to be the primary bottleneck at most settings.

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

The Ryzen 7 5800X3D brings 8 physical cores and 16 threads to the table, built on TSMC’s 7 nm process with 8,850 million transistors within a 74 mm² die. For Doom, a fast-paced FPS, the 96 MB of shared L3 cache is a critical asset; it allows frequently accessed game data to reside closer to the cores, reducing the need to pull from system memory (DDR4, dual-channel, 51.2 GB/s bandwidth). The CPU’s single-thread performance, as shown by a 3dmark_single_thread score of 884, is competent but not class-leading; its multi-threaded potential, however, is substantial, with a cinebench_r23_multicore score of 24063.

Benchmark results indicate that the 5800X3D’s performance parity with rivals like the Core i9-11900K (deltaPct 0.1) and Ryzen 5 7600 (deltaPct -0.2) in average scores means the processor delivers consistent frame delivery without being a limiting factor. In Doom’s measured data, the CPU’s role becomes clearer when examining resolution scaling: at 1920x1080 with Low settings, the combo achieves 175.4 FPS, which is likely near the CPU’s ceiling for this engine. As resolution increases to 2560x1440 and 3840x2160, the FPS drops, indicating the workload shifts towards the GPU. The 5800X3D’s 16 threads are more than sufficient for Doom’s engine, which typically scales well up to 8 cores. The 3dmark_16_threads score of 7299 versus 3dmark_8_threads score of 5906 shows a 23.6% gain from additional threads, but the game’s engine does not appear to demand that extra headroom, given the observed frame rates.

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

The AMD Radeon RX 6600, based on the Navi 23 chip (RDNA 2.0 architecture, 7 nm, 11,060 million transistors), provides 8 GB of GDDR6 memory on a 128-bit bus, delivering 224.0 GB/s of bandwidth. Its boost clock reaches 2491 MHz, with a game clock of 2044 MHz, and it features 1792 shading units, 112 TMUs, and 64 ROPs. The GPU’s pixel rate is 159.4 GPixel/s and texture rate is 279.0 GTexel/s, with FP32 performance at 8.928 TFLOPS. This GPU sits at the 69th percentile among all tested GPUs, with an average benchmark score of 25235. Its nearest rivals include the AMD Radeon 890M (deltaPct 0), the AMD Radeon RX 580 2048SP (deltaPct -0.2), the AMD Radeon RX 6700M (deltaPct 0.2), and the NVIDIA GeForce RTX 3060 Ti (deltaPct 0.5). These tiny deltas imply the RX 6600 performs nearly identically to these cards in general benchmarks.

In Doom, the RX 6600’s 8 GB VRAM is sufficient for all tested settings, even at 4K Ultra, where the average FPS is 38.1. The GPU’s role becomes dominant as resolution increases. At 1080p Low, the 175.4 FPS is likely constrained by the CPU, but at 4K Ultra, the 38.1 FPS is clearly GPU-bound. The memory bandwidth of 224.0 GB/s is a potential limiting factor at higher resolutions; however, the data shows that the RX 6600 still delivers playable frame rates at 1440p High (82 FPS) and 4K Low (63.6 FPS). The GPU’s boost clock of 2491 MHz provides ample compute power for Doom’s Vulkan-based engine, which is known for efficient multi-threading and low overhead.

A: The CPU’s average benchmark score (26574) is nearly identical to rivals like the Core i9-11900K (26546), so the cache does not create a significant lead in Doom. The game appears more sensitive to GPU load, as evidenced by the FPS scaling with resolution.

Q: Can this combo handle 4K gaming in Doom?

A: Yes, but with compromises. At 3840x2160, Low settings deliver 63.6 FPS, Medium 54.4 FPS, High 48.1 FPS, and Ultra 38.1 FPS. For a smooth 60 FPS experience, Low settings are required.

Q: How does the combo rank among all tested configurations?

A: The combo ranks 1332 out of 1681 tested combos, placing it in the lower-middle tier. This is due to the GPU’s mid-range standing (69th percentile) and the CPU’s high but not top-tier position (83rd percentile).

How This Combo Ranks

The combo’s rank of 1332 out of 1681 total tested combinations places it in the 21st percentile overall (calculated by position). This is a modest ranking, driven by the RX 6600’s mid-range performance (69th percentile among GPUs) rather than the CPU, which sits at the 83rd percentile. The data suggests that in Doom, the GPU is the primary determinant of the combo’s overall standing. To interpret: this pairing is not designed for maximum frame rates at 4K, but it offers a balanced experience for 1080p and 1440p gaming. The rank implies that 349 other combos perform worse, meaning there is headroom for this system to deliver playable results in most scenarios, but it will not compete with high-end GPU pairings. The measured FPS values confirm this: at 1440p High, it hits 82 FPS, which is respectable, but at 4K Ultra, it drops to 38.1 FPS, which is below the 60 FPS threshold typically desired.

Settings Recommendations

For the best experience, the measured data suggests prioritizing resolution over ultra-high settings. At 1920x1080, all settings presets yield playable frame rates: Low (175.4), Medium (151.6), High (131.2), and Ultra (108.7). The jump from High to Ultra costs 22.5 FPS (17.2% reduction), making High the sweet spot for visual fidelity and smoothness. At 2560x1440, the story changes: Low (113), Medium (100.4), and High (82) are all above 60 FPS, but Ultra (68.6) barely clears it. For a consistent 60+ FPS experience at 1440p, High is recommended, as it provides a 13.4 FPS advantage over Ultra (82 vs 68.6). At 3840x2160, only Low (63.6) and Medium (54.4) are within reach of 60 FPS; High (48.1) and Ultra (38.1) are below. To maintain a playable frame rate at 4K, Low is the only preset that averages above 60 FPS, though Medium is acceptable for slower-paced moments. The optimal overall choice depends on the display: for 1080p/1440p, High offers the best balance; for 4K, Low is necessary for smooth play.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the combo’s capabilities across resolutions and settings.

1920x1080: Low averages 175.4 FPS, Medium 151.6 FPS, High 131.2 FPS, and Ultra 108.7 FPS. The scaling from Low to Ultra shows a 38.0% performance reduction, indicating that the GPU is handling the load well, but the CPU is not a limiting factor at these settings, given the high frame rates.

2560x1440: Low averages 113 FPS, Medium 100.4 FPS, High 82 FPS, and Ultra 68.6 FPS. The drop from 1080p Low to 1440p Low is 62.4 FPS (35.6% decrease), showing a significant resolution penalty. Ultra at 1440p is still above 60 FPS, making it a viable option for gamers who prefer max settings.

3840x2160: Low averages 63.6 FPS, Medium 54.4 FPS, High 48.1 FPS, and Ultra 38.1 FPS. The transition to 4K is harsh: even Low settings suffer a 49.4 FPS loss compared to 1440p Low. Ultra at 4K is only 38.1 FPS, which is a 64.9% drop from 1080p Ultra (108.7 FPS). This resolution is clearly GPU-bound, with the RX 6600’s 8 GB VRAM and 224.0 GB/s bandwidth struggling to keep up.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and reveals the limiting component. Moving from 1920x1080 Low (175.4 FPS) to 2560x1440 Low (113 FPS) is a 35.6% reduction, and then to 3840x2160 Low (63.6 FPS) is another 43.7% reduction from 1440p. This pattern is consistent across all settings: High goes from 131.2 (1080p) to 82 (1440p) to 48.1 (4K), a cumulative 63.3% loss. Ultra goes from 108.7 to 68.6 to 38.1, a 64.9% loss. These percentages indicate a near-linear scaling with pixel count (1080p to 4K is 4x the pixels, but frame rates drop by roughly 60-65%, not 75%). The fact that the drop is less than linear suggests the CPU is partially mitigating the GPU load at lower resolutions, but at 4K, the GPU is fully saturated. The RX 6600’s memory bandwidth of 224.0 GB/s is likely the bottleneck at 4K, as the 8 GB VRAM capacity is sufficient, but the 128-bit bus cannot feed the shaders fast enough. The CPU’s 96 MB L3 cache helps at 1080p, where the 175.4 FPS Low result indicates the processor can push the engine hard, but as resolution rises, the GPU’s raw compute and memory throughput dictate the outcome. This analysis confirms that the combo is balanced for 1080p and 1440p, but 4K requires significant settings reductions to remain playable.
