Doom

The AMD Ryzen 9 5950X paired with the NVIDIA GeForce RTX 3080 delivers a commanding performance in Doom, a title where frame rates scale dramatically with both resolution and graphical preset. The data shows a system that can easily handle high-refresh-rate 1440p gaming and remains highly playable at 4K, though the gap between settings tiers widens considerably as pixel count increases.

Resolution Scaling

The measured FPS reveals a classic GPU-bound scaling pattern as resolution climbs. At 1080p with Low settings, the combo reaches an average of 301 FPS, which drops to 195 FPS at 1440p and 105 FPS at 4K. This represents a 35% reduction when moving from 1080p to 1440p and a further 46% reduction when stepping up to 4K. Such steep declines are the signature of a system where the graphics card is doing the heavy lifting, and the CPU's headroom is not the limiting factor at higher resolutions.

The scaling behavior changes noticeably when looking at Ultra settings. At 1080p Ultra, the average is 181 FPS; at 1440p Ultra, it falls to 117 FPS; and at 4K Ultra, it drops to 63 FPS. The percentage drop from 1080p to 1440p is about 35%, similar to the Low preset, but the drop from 1440p to 4K is steeper at 46%. This intensified decline at 4K Ultra suggests that the RTX 3080's 10 GB frame buffer and memory bandwidth are being pushed harder, and the GPU is nearing its practical limits with the most demanding settings.

The delta between Low and Ultra presets also grows with resolution. At 1080p, the difference between Low and Ultra is 120 FPS (301 vs 181). At 1440p, the gap narrows to 78 FPS (195 vs 117). At 4K, it further compresses to 42 FPS (105 vs 63). This compression indicates that at higher resolutions, the GPU becomes the bottleneck regardless of settings, and the performance headroom that exists at 1080p simply evaporates. For a game like Doom, which is known for its fast pace, the 4K Ultra result of 63 FPS is still smooth, but it is a far cry from the triple-digit figures achievable at lower resolutions.

GPU Role

The NVIDIA GeForce RTX 3080 is the primary driver of these results, and its specifications explain why the scaling behaves as it does. Built on the Ampere architecture with a GA102 chip on an 8 nm process, this card carries 10 GB of GDDR6X memory on a 320-bit bus, delivering a bandwidth of 760.3 GB/s. The memory clock runs at 1188 MHz, which translates to 19 Gbps effective. This bandwidth is crucial for Doom's texture-heavy environments, especially at 4K where the demand for memory throughput increases sharply.

The GPU's clock speeds are modest by modern standards — a base of 1440 MHz and a boost of 1710 MHz — but the architecture's efficiency compensates. With 8704 shading units, 272 texture mapping units, and 96 ROPs, the card has substantial raw compute to draw upon. The FP32 performance of 29.77 TFLOPS and a texture rate of 465.1 GTexel/s indicate a GPU that can handle the rapid-fire rendering demands of an FPS title without breaking a sweat at lower resolutions.

The benchmark results for the GPU place it in the 68th percentile of all GPUs, with an average benchmark score of 23172. Its nearest rivals in the database include the NVIDIA P106-100, AMD Radeon Pro Vega 16, and AMD Radeon RX 6600M, all of which sit within 0.4% of the RTX 3080's average score. This clustering suggests that while the RTX 3080 is a strong performer, it is not in the top tier of GPUs by synthetic benchmarks alone. However, in Doom, the measured FPS shows a card that is more than adequate for high-refresh-rate 1440p gaming, and it remains capable at 4K with settings adjusted.

The 10 GB VRAM capacity is worth noting. At 4K Ultra, the game demands more memory, and while the card does not appear to suffer from capacity-related stutters in the measured data (the Medium preset shows a min FPS of 78 and max of 106 at 4K), the margin for error is thinner than with higher-capacity cards. The 63 FPS average at 4K Ultra indicates the GPU is working hard, and further increases in texture quality or resolution would likely push it past its comfort zone.

CPU Role

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture, codenamed Vermeer, on a 7 nm TSMC process. Its base clock of 3.40 GHz and boost clock of 4.90 GHz provide strong single-thread performance, which is what Doom primarily leverages. The CPU's 64 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth ensure that data feeding the GPU is not a bottleneck.

In synthetic benchmarks, the 5950X shows its strength. Its Cinebench R23 multi-core score of 26017 and single-core score of 1614 highlight a processor that excels in both heavily threaded and lightly threaded workloads. The 3DMark results, ranging from 944 in single-thread to 11597 in max-threads, reinforce this dual nature. The CPU sits in the 91st percentile of all CPUs, with an average benchmark score of 51947. Its nearest rivals include the Intel Core Ultra 5 235HX (within 0.2%), AMD EPYC 8124P (within 0.3%), and Intel Core i9-13900F (within 0.4%), all of which are within a rounding error of each other.

For Doom, which was released in 2016 and is known for its Vulkan API support, the CPU's role is less about raw core count and more about per-core efficiency. The 5950X's 4.90 GHz boost clock ensures that frame pacing remains tight, and the measured FPS data supports this. At 1080p Low, the average of 301 FPS shows that even at extremely high frame rates, the CPU is not holding the system back. The jump from 1440p to 1080p at Low settings (195 to 301 FPS, a 54% increase) suggests that the CPU can push well beyond 300 FPS if the GPU were not limited.

The CPU's 16 cores and 32 threads are overkill for this title, but they provide headroom for background tasks, streaming, or other applications running concurrently. The data indicates that in Doom, the CPU is never the limiting component. Even at 1080p with the lowest settings, the system is GPU-bound, and the 5950X's job is simply to feed frames fast enough. Its PassMark single-thread score of 3470 and multi-thread score of 45424 confirm that it has the horsepower to keep up with the RTX 3080's output.

How This Combo Ranks

This specific combination of the AMD Ryzen 9 5950X and NVIDIA GeForce RTX 3080 ranks 1054th out of 3712 tested combos for Doom. This places it in the top 28% of all configurations, which is a solid standing given the game's age and the sheer number of systems tested. The rank reflects a balance between the CPU's high percentile (91st) and the GPU's more moderate percentile (68th). The GPU drags the overall ranking down relative to what the CPU alone might achieve, but the measured FPS shows that this pairing still delivers excellent real-world performance.

The combo's rank of 1054 suggests that there are many faster configurations, likely those pairing top-tier GPUs like the RTX 3090 or newer cards with equally strong CPUs. However, within the context of the RTX 3080's generation, this is a well-matched pair. The CPU's 32 threads ensure that no game logic or physics calculation will ever stutter, and the GPU's 10 GB of memory and 760.3 GB/s bandwidth handle the rendering duties competently. The delta between the CPU's benchmark percentile and the GPU's is notable — the 5950X is in the 91st percentile of all CPUs, while the RTX 3080 sits in the 68th percentile of all GPUs — which indicates that the GPU is the more likely upgrade path for improving this combo's rank in future tests.

Measured FPS Breakdown

The measured data provides a clear picture of performance across three resolutions and four settings presets. At 1920x1080, the combo achieves its highest averages: 301 FPS on Low, 262 FPS on Medium (with a min of 223 and max of 301), 221 FPS on High, and 181 FPS on Ultra. These numbers are all well above the 144 Hz refresh rate that most high-end monitors offer, meaning the system will never be the limiting factor in a competitive match.

At 2560x1440, the averages drop but remain impressive: 195 FPS on Low, 170 FPS on Medium (min 144, max 195), 143 FPS on High, and 117 FPS on Ultra. The Medium preset's minimum of 144 FPS is exactly the refresh rate of many 1440p gaming monitors, so users with such displays will see a locked 144 FPS experience. The Ultra preset's 117 FPS average is still smooth for fast-paced gameplay, though it leaves some headroom on the table.

At 3840x2160, the performance becomes more modest: 105 FPS on Low, 92 FPS on Medium (min 78, max 106), 78 FPS on High, and 63 FPS on Ultra. The 4K Ultra result of 63 FPS is just below the 60 FPS threshold that some consider the minimum for playable, but it is still within a range that most gamers would find acceptable for a single-player FPS. The Low preset at 4K achieves 105 FPS, which is a significant improvement over Ultra, showing that the settings preset has a substantial impact at this resolution.

Settings Recommendations

For 1440p gaming, the data strongly supports using the High preset. The average of 143 FPS aligns perfectly with a 144 Hz monitor, and the step up to Ultra only costs 26 FPS (from 143 to 117) while providing marginal visual gains. The Medium preset at 1440p offers 170 FPS, which is beneficial for those with 165 Hz or 170 Hz displays, but the visual fidelity drop may not be worth the extra 27 FPS for most players.

At 1080p, the High preset at 221 FPS is the sweet spot for competitive play. The jump from High to Ultra costs 40 FPS (from 221 to 181), but both are far above any refresh rate that current monitors support. Users with 240 Hz displays might prefer the Medium preset's 262 FPS, which gets closer to that threshold, though the difference in visual quality is noticeable. For pure competitive advantage, Low at 301 FPS is the maximum possible, but it sacrifices too much visual detail for most players.

At 4K, the recommendation is more nuanced. The High preset at 78 FPS is the best balance of visual quality and smoothness, as it stays above 60 FPS while delivering a substantial upgrade over Medium. The Ultra preset at 63 FPS is playable, but it leaves no headroom for frame drops, and the Medium preset at 92 FPS is a safer choice for those who prioritize a locked frame rate. The Low preset at 105 FPS is the performance pick, but it undermines the point of 4K rendering. Given that the Medium preset has measured minimums of 78 FPS at 4K, it is the recommended choice for users who want a consistent experience without dipping below 60 FPS.
