Doom

The AMD Ryzen 9 9950X3D and NVIDIA GeForce RTX 3080 combination delivers a remarkably consistent experience in Doom, with the data showing that the game’s performance scaling is almost entirely dictated by the GPU. Across the three tested resolutions, the transition from 1920x1080 to 2560x1440 and then to 3840x2160 produces predictable frame rate drops that align with the increase in pixel count, while the CPU’s substantial multi-threading capabilities remain largely untapped. The measured FPS values indicate a system that is well-balanced for high-refresh-rate 1440p gaming, but which begins to show the RTX 3080’s memory and bandwidth constraints at 4K Ultra settings.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings presets, which is a classic hallmark of GPU-bound rendering. At Low settings, the average frame rate falls from 302.2 FPS at 1920x1080 to 197.3 FPS at 2560x1440, a reduction of 104.9 FPS, and then further down to 104.9 FPS at 3840x2160. This pattern shows that doubling the resolution nearly halves the frame rate, indicating that the RTX 3080’s shading units and memory bandwidth are the limiting factors rather than the CPU. At Ultra settings, the scaling is even more pronounced: 183.8 FPS at 1080p drops to 119.6 FPS at 1440p and then to 61.8 FPS at 4K. The 4K Ultra result of 61.8 FPS is the only measurement in the entire dataset that falls below the 60 FPS threshold, suggesting that this particular combination is not ideal for maximum fidelity at 4K.

The data reveals that the gap between Low and Ultra settings widens as resolution increases. At 1080p, the difference between Low and Ultra is 118.4 FPS (302.2 vs 183.8), while at 4K, the same comparison yields a difference of only 43.1 FPS (104.9 vs 61.8). This compression of the settings range at higher resolutions further confirms that the GPU is the primary bottleneck; at 4K, even lowering settings cannot fully compensate for the raw pixel throughput required. The 2560x1440 resolution presents the most balanced profile, with High settings achieving 142.1 FPS and Ultra still maintaining a very playable 119.6 FPS, demonstrating that this resolution is the sweet spot for this hardware pairing.

GPU Role

The NVIDIA GeForce RTX 3080, built on the Ampere architecture with a GA102 chip, is the decisive component in these results. The GPU’s 10 GB of GDDR6X memory on a 320-bit bus provides 760.3 GB/s of bandwidth, which is sufficient for 1080p and 1440p but becomes strained at 4K Ultra. The benchmark scores for the GPU place it in the 80th percentile among all GPUs, with an average benchmark score of 35787. Its nearest rival, the AMD Radeon Pro Duo, scores 35860, a delta of -0.2%, indicating that the RTX 3080 is virtually tied with that competitor in raw compute performance. However, the measured FPS in Doom shows that real-world gaming performance can diverge from synthetic averages, as the game’s engine appears to favor the RTX 3080’s specific architecture.

The clock speeds of 1440 MHz base and 1710 MHz boost are modest for a high-end card, but the 8704 shading units and 272 TMUs compensate by providing massive parallel throughput. The GPU’s 29.77 TFLOPS of FP32 performance is the theoretical ceiling, and the data suggests that Doom’s Vulkan-based engine can approach this limit at lower resolutions. At 1080p Low, the 302.2 FPS result indicates that the GPU is almost fully utilized, with the CPU waiting for frames rather than the reverse. The 320 W TDP is a substantial power draw, but the performance per watt appears favorable given the high frame rates achieved at 1440p. The GPU’s position in the 80th percentile, with rivals like the AMD Radeon 880M scoring 35646 (a delta of 0.4%), confirms that this card remains competitive, though the 10 GB memory capacity is a notable limitation for future titles.

FAQ

Q: What is the maximum average FPS achievable with this CPU/GPU combo in Doom?

A: The highest measured average FPS is 302.2, achieved at 1920x1080 resolution with Low settings. This indicates that the combination can push well beyond typical 144Hz monitors when resolution and settings are reduced.

Q: Can this system maintain 60 FPS at 4K with maximum settings?

A: Yes, but just barely. At 3840x2160 with Ultra settings, the average FPS is 61.8. This is above 60, but the margin is slim, and any demanding scene could potentially drop below that threshold.

Q: How does the RTX 3080 compare to its closest rival in synthetic benchmarks?

A: The RTX 3080 has an average benchmark score of 35787, while its nearest rival, the AMD Radeon Pro Duo, scores 35860. This represents a delta of -0.2%, meaning the RTX 3080 is statistically tied with that card in aggregate performance.

Q: What is the performance difference between High and Ultra settings at 1440p?

A: At 2560x1440, High settings produce an average of 142.1 FPS, while Ultra settings produce 119.6 FPS. The difference is 22.5 FPS, or roughly 16% lower performance for Ultra, which may not be visually significant in a fast-paced FPS.

Q: Does the CPU’s multi-threading capability influence the frame rates at 1080p?

A: The data suggests minimal CPU influence. At 1080p Low, the CPU’s 16 cores and 32 threads are more than sufficient, as evidenced by the 302.2 FPS result. The CPU’s average benchmark score of 71660 places it in the 96th percentile, but the game clearly does not stress it.

Q: What is the ideal settings preset for a 144Hz monitor?

A: For a 144Hz display, either High or Ultra at 2560x1440 would work, with High providing 142.1 FPS and Ultra providing 119.6 FPS. Alternatively, 1080p Ultra at 183.8 FPS would also comfortably exceed the refresh rate.

Measured FPS Breakdown

At 1920x1080, the data shows a clear hierarchy of performance across settings. Low settings deliver 302.2 FPS, Medium drops to 260.8 FPS, High reduces further to 222.7 FPS, and Ultra bottoms out at 183.8 FPS. This represents a 39% reduction in frame rate from Low to Ultra, which is a significant penalty for the visual upgrades. The 1080p results are universally above the refresh rate of most gaming monitors, making this resolution ideal for competitive play where frame rate is paramount.

Moving to 2560x1440, the frame rates remain high but begin to show the GPU’s workload. Low settings produce 197.3 FPS, Medium achieves 171.4 FPS, High manages 142.1 FPS, and Ultra falls to 119.6 FPS. The step from High to Ultra is 22.5 FPS, which is the smallest gap between consecutive settings at this resolution, suggesting diminishing returns from the highest preset. All 1440p results exceed 60 FPS, and all except Ultra exceed 120 FPS, making this the recommended resolution for a smooth experience.

At 3840x2160, the performance drops become more pronounced. Low settings yield 104.9 FPS, Medium drops to 93.7 FPS, High achieves 76 FPS, and Ultra falls to 61.8 FPS. The 4K results are the only ones where any preset dips below 100 FPS, and the Ultra preset’s 61.8 FPS is the sole measurement below 60 FPS in the entire dataset. The difference between Low and Ultra at 4K is 43.1 FPS, which is proportionally smaller than at lower resolutions, confirming that the pixel fill rate is the dominant constraint.

CPU Role

The AMD Ryzen 9 9950X3D is a formidable processor, with 16 cores and 32 threads based on the Zen 5 architecture in the Granite Ridge codename. Its base clock of 4.30 GHz and boost clock of 5.70 GHz, combined with 128 MB of shared L3 cache, make it an absolute powerhouse for multi-threaded workloads. The CPU’s benchmark scores reflect this: it achieves a Cinebench R23 multicore score of 59712 and a Geekbench multicore score of 22515. These numbers place the CPU in the 96th percentile of all CPUs, with an average benchmark score of 71660.

However, the measured FPS data in Doom shows that the CPU is rarely the limiting factor. The nearest rival, the Intel Xeon Platinum 8270, has an average score of 71056, a delta of only 0.9%, meaning the 9950X3D is only marginally faster in aggregate. Yet in gaming, the 9950X3D’s high single-thread performance, evidenced by a Passmark single-thread score of 4737, ensures that even at 1080p with Low settings, the CPU can feed frames fast enough to reach 302.2 FPS. The data indicates that the CPU’s role is to provide headroom; at 4K Ultra, the GPU is clearly the bottleneck, as the CPU’s performance is not the reason for the 61.8 FPS result. The 9950X3D’s 170 W TDP and support for DDR5 memory further solidify its position as a top-tier gaming processor, but in this specific game, its advantages are largely untapped.

Settings Recommendations

Based on the measured data, the optimal settings preset depends entirely on the target resolution and refresh rate. For 1920x1080, the High preset at 222.7 FPS offers a strong balance between visual quality and performance, while Ultra at 183.8 FPS is still excellent and provides the best image quality. Given that both exceed 144 FPS, players with 144Hz monitors should choose Ultra for the best visuals, while those with 240Hz or higher displays might prefer High to maximize frame rate.

At 2560x1440, the High preset at 142.1 FPS is the recommended choice for most users, as it provides a near-perfect 144Hz experience. Ultra at 119.6 FPS is also viable and offers a visual upgrade, but the 22.5 FPS penalty may not be worth it in a fast-paced FPS where frame rate matters. For players with 120Hz monitors, Ultra is a better pick, as it stays above the refresh rate.

At 3840x2160, the situation is more nuanced. The Ultra preset at 61.8 FPS is right at the edge of playability, so Medium at 93.7 FPS is the safer recommendation for a smooth experience. High at 76 FPS is a good middle ground, offering better visuals than Medium while maintaining a comfortable frame rate. For 4K, the data shows that dropping to Low at 104.9 FPS is unnecessary, as Medium provides a substantial visual improvement with only an 11.2 FPS penalty. Ultimately, the sweet spot for this hardware is 2560x1440 with High settings, which delivers 142.1 FPS and represents the best compromise between image quality and performance.
