# Doom with AMD Ryzen 9 5900X + NVIDIA GeForce GTX 1650

The AMD Ryzen 9 5900X paired with the NVIDIA GeForce GTX 1650 delivers a playable experience in Doom at 1080p, but struggles at higher resolutions. This combination ranks 1582nd out of 1681 tested combos for this game, placing it in the bottom 6% of configurations. The data shows a clear pattern: the GTX 1650 is the limiting factor at 1440p and 4K, while the Ryzen 9 5900X has ample headroom that never gets fully utilized.

FAQ

Q: What is the highest average FPS this combo achieves in Doom?

A: The highest measured average is 94.3 FPS at 1920x1080 with Low settings. At the same resolution, Medium produces 81.8 FPS, High produces 66.4 FPS, and Ultra drops to 57.7 FPS.

Q: Can this system maintain 60 FPS at 1440p?

A: Only at Low settings, where the average is 59.9 FPS. Medium yields 55.1 FPS, High yields 44.4 FPS, and Ultra falls to 38.3 FPS. None of these averages reach 60 FPS except the Low preset, which barely touches it.

Q: How does the GTX 1650 compare to its nearest rivals?

A: The GTX 1650 has an average benchmark score of 8713, placing it in the 43rd percentile of all GPUs. It sits within 0.5% of the NVIDIA Quadro P2200 (8671), and within 0.4% of both the NVIDIA GeForce RTX 3050 A Mobile (8746) and AMD Radeon 550X (8749).

Q: What is the worst performance scenario for this combo?

A: At 3840x2160 with Ultra settings, the average FPS drops to 16.3. This is the lowest measured result across all tested configurations, making 4K Ultra effectively unplayable.

Q: How does the Ryzen 9 5900X rank among all CPUs?

A: The processor sits in the 90th percentile of all CPUs, with an average benchmark score of 39453. Its closest rival, the AMD EPYC 4245P, scores 39383 (0.2% lower), while the Intel Core i7-13700 scores 39857 (1% higher).

Q: Does the 4 GB VRAM on the GTX 1650 limit performance?

A: The data indicates the GPU is the bottleneck at higher resolutions. At 4K, the FPS drops dramatically across all settings, with Ultra at 16.3 FPS versus Low at 34.4 FPS, suggesting the GPU's memory bandwidth and compute capacity are overwhelmed.

CPU Role

The Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture (Vermeer codename), built on TSMC's 7 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.80 GHz, with 64 MB of L3 cache. The processor supports DDR4 memory in dual-channel configuration with 51.2 GB/s bandwidth, and its PCIe Gen 4 interface provides ample bandwidth for modern GPUs.

In Doom, the CPU's role is largely secondary. The game's measured FPS at 1080p ranges from 57.7 FPS at Ultra to 94.3 FPS at Low, but these numbers are constrained by the GPU. The CPU's benchmark scores show massive headroom: Cinebench R23 multicore scores 33150, and PassMark multithread scores 39002. Single-thread performance is also strong, with Geekbench single-core at 2202 and Cinebench R23 single-core at 4680.

The data suggests the CPU is never the bottleneck in these tests. At 4K, the FPS difference between Low (34.4) and Ultra (16.3) is 111% — a GPU-driven spread. The processor's 90th percentile ranking means it outperforms 90% of all CPUs, yet the GTX 1650's 43rd percentile ranking shows the GPU is mid-pack at best. The CPU's capabilities are far beyond what this game requires at the tested settings.

GPU Role

The GTX 1650 is a Turing-architecture GPU (TU117 chip) built on TSMC's 12 nm process. It has 896 shading units, 56 TMUs, and 32 ROPs, with a base clock of 1485 MHz and boost clock of 1665 MHz. Memory consists of 4 GB of GDDR5 on a 128-bit bus, delivering 128.1 GB/s of bandwidth. The GPU's FP32 performance is 2.984 TFLOPS, and it has a 75 W TDP with no power connectors required.

This GPU is clearly the dominant factor in Doom's performance. At 1080p, the average FPS ranges from 57.7 (Ultra) to 94.3 (Low), which is a 63% spread between the lowest and highest presets. At 1440p, the spread narrows to 56% (38.3 to 59.9 FPS), and at 4K, it widens again to 111% (16.3 to 34.4 FPS). The 4 GB VRAM and 128.1 GB/s bandwidth become increasingly stressed as resolution increases.

The GPU's benchmark profile shows a PassMark G3D score of 7880 and a 3DMark Steel Nomad DX12 score of 305. Its average benchmark score of 8713 places it at 43% percentile of all GPUs, meaning it is outclassed by over half of available graphics cards. The nearest rivals are all within 0.5% of its score, indicating tight competition in this performance class, but none of them would fundamentally change the gaming experience at higher resolutions.

Measured FPS Breakdown

At 1920x1080, the combo delivers playable frame rates across all presets. Low settings produce an average of 94.3 FPS, which is smooth for a fast-paced FPS. Medium drops to 81.8 FPS, High to 66.4 FPS, and Ultra to 57.7 FPS. The spread from Low to Ultra is 36.6 FPS, showing that visual quality comes at a measurable cost.

At 2560x1440, performance falls below the 60 FPS threshold for most presets. Low averages 59.9 FPS, barely hitting the target. Medium produces 55.1 FPS, High drops to 44.4 FPS, and Ultra falls to 38.3 FPS. The difference between Low and Ultra here is 21.6 FPS, a narrower gap than at 1080p, indicating the GPU is becoming the binding constraint.

At 3840x2160, the experience degrades significantly. Low averages 34.4 FPS, Medium 30.5 FPS, High 26.5 FPS, and Ultra plummets to 16.3 FPS. None of these are acceptable for a competitive shooter, and even the best 4K result (Low at 34.4 FPS) is below the 60 FPS target. The gap between Low and Ultra at 4K is 18.1 FPS, but the proportional difference is the largest of any resolution.

Resolution Scaling

The transition from 1080p to 1440p to 4K reveals a predictable pattern of frame rate decline. At Low settings, the average FPS drops from 94.3 at 1080p to 59.9 at 1440p (a 36% reduction), then to 34.4 at 4K (a further 43% reduction). At Ultra settings, the drop is from 57.7 at 1080p to 38.3 at 1440p (34% reduction), then to 16.3 at 4K (57% reduction).

This scaling behavior indicates the GPU is the limiting component. The 4K-to-1080p ratio for Low settings is 34.4/94.3 = 0.365, meaning 4K delivers only 36.5% of the 1080p frame rate. For Ultra, the ratio is 16.3/57.7 = 0.283, or 28.3%. The fact that higher settings cause a steeper drop at 4K suggests the GPU's compute and memory resources are exhausted more quickly when both resolution and graphical complexity increase.

The CPU's role in this scaling is negligible. The Ryzen 9 5900X's Cinebench R20 multicore score of 13923 and PassMark physics score of 1994 indicate substantial processing capability, yet the FPS figures at all resolutions are governed by the GTX 1650's limits. In effect, the processor is waiting on the GPU to render frames.

Settings Recommendations

Based on the measured data, the optimal preset depends on the target resolution and desired frame rate. At 1920x1080, Medium settings (81.8 FPS) offer the best balance of smoothness and visual fidelity, as High (66.4 FPS) still comfortably exceeds 60 FPS while providing better image quality. Ultra at 57.7 FPS is borderline, dipping below the ideal threshold but remaining playable for slower-paced segments.

At 2560x1440, Low settings (59.9 FPS) are the only preset that reaches near-60 FPS performance. Medium (55.1 FPS) is a reasonable alternative if slight stutter is acceptable, but the data indicates Low is the safer choice for maintaining fluid gameplay. High (44.4 FPS) and Ultra (38.3 FPS) are noticeably less smooth.

At 3840x2160, no preset achieves a playable frame rate. Even Low at 34.4 FPS falls short of the 60 FPS target, and Ultra at 16.3 FPS is effectively a slideshow. The recommendation is to avoid 4K with this combo entirely, or accept that performance will be sub-optimal regardless of settings.

For the best overall experience, 1080p with High settings provides 66.4 FPS — a solid compromise that leverages the CPU's headroom while acknowledging the GPU's limitations. Users prioritizing frame rate over visuals should select Low at 1080p for 94.3 FPS, which is the single highest measured result in this dataset.
