Doom

How This Combo Ranks

This AMD Ryzen 7 5800X + NVIDIA GeForce RTX 3080 Ti combination ranks 963rd out of 3712 tested combos for Doom, placing it in the top quarter (roughly the 74th percentile) of all systems evaluated. That’s a strong position, but not a dominant one — the game is well-optimized, and many newer CPUs and GPUs edge this pairing out on raw frame rates. The ranking reflects a balanced system: the 5800X is an 8-core/16-thread Zen 3 part with a 3.80 GHz base clock and 4.70 GHz boost, while the RTX 3080 Ti is a high-end Ampere card with a 1365 MHz base and 1665 MHz boost clock. In Doom, a game that scales well across hardware, this combo lands in the upper tier without being exceptional.

The deltaPct values from the nearest rivals show how tight the CPU’s performance envelope is. The Intel Core Ultra 5 135H scores 0.1% higher on average, while the Intel Xeon Phi 7210 is 0.4% lower, and the Intel Core i5-13500HX trails by 0.5%. The AMD Ryzen 5 5600XT is 0.6% behind. These are all sub-1% differences, meaning the 5800X sits in a very dense cluster of processors where no single chip has a meaningful edge in this game. For Doom specifically, the CPU is not the bottleneck; the GPU does the heavy lifting, and the 5800X’s multi-threaded scores (e.g., 7586 in 3dmark_16_threads, 7578 in max_threads) are more than sufficient to feed the GPU at high frame rates.

The combo’s rank is also shaped by the GPU’s overall standing. The RTX 3080 Ti holds the 83rd percentile among all GPUs, with an average benchmark score of 41187. Its nearest rival, the AMD Radeon Pro 5300, is just 0.8% behind, while the NVIDIA Tesla M40 24GB is 1.2% ahead, and the GeForce RTX 5070 is 2% behind. These small deltas suggest the 3080 Ti occupies a well-balanced performance tier, with no single competitor running away in synthetic tests. In Doom, that balance translates to consistent 1080p and 1440p performance, but at 4K Ultra, the frame rate dips noticeably—more on that in the resolution section.

GPU Role

The RTX 3080 Ti’s memory and clock specs are central to how it handles Doom. The card has 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s bandwidth —plenty for Doom’s textures and effects, even at 4K. The GPU’s shading units (10240) and texture rate (532.8 GTexel/s) mean it can push high pixel rates, and the 186.5 GPixel/s pixel rate explains why even at 4K High it sustains 81 FPS average. The boost clock of 1665 MHz is modest by modern standards, but the card’s massive shading and TMU count (320) compensates, giving it a strong FP32 throughput of 34.10 TFLOPS.

In Doom, the GPU’s memory bandwidth becomes a limiting factor at 4K when settings rise. At 3840x2160 Ultra, the average FPS drops to 66, while High stays at 81. The gap between Low (109 fps) and High (81 fps) shows that memory bandwidth and shading performance—not CPU—are the binding constraints at this resolution. The card’s FP32 rating of 34.10 TFLOPS is high, but Doom’s rendering at 4K demands more from the memory subsystem than the compute units; the 912.4 GB/s bandwidth is enough for 1080p and 1440p, but at 4K, the card’s 12 GB capacity is not the issue—it’s the bandwidth that limits the frame rate when effects are maxed.

The 3080 Ti’s boost clock of 1665 MHz is a modest lift from its base (1365 MHz) and is not the source of its strength in this benchmark. Instead, the 10240 shading units and 320 TMUs allow it to maintain high frame averages even at 1440p Ultra (122 fps), which competitors with fewer compute units might struggle to match. The GPU’s 83rd percentile ranking among all GPUs matches the observed performance. It is a capable card for Doom’s engine, but it is not in the top tier (like a 4090), so at 4K, you need to pick settings carefully—Ultra is playable but the 63 fps average is tight for a fast-paced shooter, and the High preset gives a more comfortable margin.

Resolution Scaling

The measured FPS at 1080p, 1440p, and 4K reveals how the bottleneck shifts with resolution. At 1920x1080, the combo is heavily CPU-limited: the Low preset hits 312 fps average, Medium 272 fps, High 230 fps, and Ultra 188 fps. These are all far above the 60 Hz threshold, and the spread from Low to Ultra (124 fps) is small relative to the jump in settings—this is a sign that the CPU is the limiting factor, since the GPU has plenty of headroom to render frames quickly. The 5800X’s single-thread performance (943 in 3dmark_single_thread) and multi-thread scores (7586 in 16 threads) are strong enough to keep the GPU fed at these resolutions.

At 2560x1440, the gap between settings widens: Low averages 202 FPS, Medium 176 FPS, High 149 FPS, and Ultra 122 FPS. The drop from 1080p Low (312) to 1440p Low (202) is a 35% reduction, which is expected as pixel count increases. But the scaling is not perfectly linear—the difference between 1080p Low and 1440p Low is 110 FPS, while from 1440p Low to 4K Low (109) is 93 FPS. This suggests the GPU starts to become more influential at 1440p, but the CPU still plays a role.

At 3840x2160, the frame rates compress: Low hits 109 FPS, Medium 95 FPS, High 81 FPS, and Ultra 63 FPS. The drop from 1080p Low (312) to 4K Low (109) is 65%, which is larger than the 55% drop from 1440p Low to 4K Low. This is typical of a GPU-bound scenario at 4K—the RTX 3080 Ti is still fast, but it can’t maintain the same frame counts at 4K, even on Low. The 4K Ultra (63 FPS) vs 1080p Ultra (188 FPS) shows a 66% reduction, which is a bigger percentage drop than the 1440p to 4K drop (from 122 to 63, a 48% reduction). This indicates that at 4K, the GPU’s memory bandwidth and shading units are the limiting factor, not the CPU.

In practical terms: if you own this combo, 1080p and 1440p are buttery smooth across all presets (even Ultra at 1440p is 122 FPS). At 4K, you need to stay at High or below to keep the average above 80 FPS, and Ultra at 63 FPS is playable but not ideal for competitive play. The data shows that the CPU is never the bottleneck at 4K—the GPU is.

Settings Recommendations

Based on the measured FPS rows, the best experience depends on your display’s refresh rate. If you have a 144Hz monitor, the 1440p High preset (149 FPS average) is the optimal choice—it stays above 144 FPS and offers a good visual uplift over Medium (176 FPS) and Low (202 FPS). At 1080p, all presets exceed 144 FPS except Ultra (188 FPS), so you can only use High (230 FPS) or Medium (272 FPS) and still get a responsive feel, but the 1440p High gives you more detail without sacrificing smoothness.

For 4K, the situation is different. If you have a 60Hz or 120Hz display, the 4K High preset (81 FPS average) is the best trade-off—it’s above 60 FPS and looks noticeably better than Medium (95 FPS) or Low (109 FPS). The Ultra preset (63 FPS) is playable but dips below 60 FPS in demanding scenes, which could cause stutter. The min FPS for 4K Medium is 81 and for 1080p Medium is 231, so the 4K Medium (95 FPS average) is also a safe bet if you want a higher frame buffer, but High’s visual quality is worth the small drop.

The data suggests that this system is overkill for 1080p—you can max out the preset and still get 188 FPS, but the GPU is not being utilized to its full potential. The sweet spot is 1440p High, which balances the 5800X’s per-core performance (single-thread score 1574.5 in Cinebench R23) and the 3080 Ti’s compute units (10240 shading, 320 TMUs) to deliver a smooth, high-refresh experience. At 4K, you must compromise on settings—High is the most balanced, while Ultra is only for those who prioritize visual fidelity over frame rate.

CPU Role

The AMD Ryzen 7 5800X is an 8-core/16-thread processor with a 3.80 GHz base clock and 4.70 GHz boost, and it earns a solid 81st percentile among all CPUs. In Doom, the CPU’s role is to keep the GPU fed, especially at 1080p and 1440p. The benchmark scores show strong multi-threading: 7586 in 3dmark_16_threads, 7578 in max_threads, and 6035 in 8 threads. These scores are high, but the single-thread scores—943 in 3dMark_single_thread and 3445 in PassMark—matter more for this game, which is not heavy on multi-threading at 1080p. The 5800X’s boost clock of 4.70 GHz helps it keep pace with the GPU’s high frame output.

However, the deltaPct values tell the real story. The 5800X is within 0.6% of several rivals—the Intel Core Ultra 5 135H (0.1% ahead), Intel Xeon Phi 7210 (-0.4% behind), and Intel Core i5-13500HX (-0.5% behind). This means that in Doom’s CPU-bound scenarios (1080p), any of these processors would perform nearly identically. The 5800X’s advantage over the Ryzen 5 5600XT is just 0.6%—a negligible margin in a game that is not CPU-limited at 1440p and 4K. The reason is that Doom’s engine scales well with core count, but the 5800X’s 8 cores are enough to avoid bottlenecks, so the extra single-thread performance is not a differentiator.

The CPU’s 32 MB L3 cache and Zen 3 architecture (7nm TSMC) contribute to its low-latency memory access, which helps in minimal in-game hitches. But at 4K, the CPU’s scores are irrelevant—the GPU is the limit. The data shows that the 5800X is never the bottleneck at any resolution in this test: even at 1080p Low (312 FPS), the CPU is still able to push the frame rate well beyond typical monitor refresh rates, and at 4K, the 3080 Ti’s shading units and memory bandwidth cap the FPS. So, if you are upgrading, the CPU is not what holds this combo back in Doom—the GPU is the component to watch for 4K.
