Doom

The AMD Ryzen 7 5800X paired with the NVIDIA GeForce GTX 1650 is a combination built on a stark performance imbalance. The data shows a CPU that ranks in the 84th percentile against all processors, paired with a GPU that sits in the 43rd percentile against all graphics cards. In Doom, this pairing results in a combo rank of 1600 out of 1681 tested combinations, placing it in the bottom 5% of systems. The benchmark results indicate that while the Ryzen 7 5800X has ample headroom, the GTX 1650 is the definitive limiting factor across nearly every resolution and settings preset.

Settings Recommendations

The measured FPS data for this combination in Doom clearly favors the Low settings preset as the only path to a consistently smooth experience. At 1920x1080, Low settings deliver an average of 92.7 FPS, which is the only preset at any resolution that approaches or exceeds the 90 FPS mark. Medium settings at 1080p produce an average of 79.4 FPS, which is playable but leaves less margin for demanding scenes. High settings at 1080p drop to an average of 69.7 FPS, still acceptable but starting to show the GPU's strain.

The Ultra preset is not recommended for this hardware. At 1920x1080, Ultra yields an average of 55.2 FPS, which is a significant drop from High and indicates the GPU's 4 GB memory buffer is being overwhelmed. The situation worsens dramatically at higher resolutions, with Ultra at 2560x1440 producing just 34.9 FPS and Ultra at 3840x2160 falling to 20.4 FPS. For the best balance of visual quality and performance, Medium at 1080p is the highest preset that maintains a reasonable frame rate, but Low at 1080p is the only setting that ensures the experience stays fluid. The data suggests that players should prioritize frame rate over visual fidelity with this GPU.

GPU Role

The NVIDIA GeForce GTX 1650 is the primary bottleneck in this configuration. With 4 GB of GDDR5 memory on a 128-bit bus providing 128.1 GB/s of bandwidth, the card is constrained in both capacity and throughput. The GPU's Turing architecture, built on a 12 nm process, features 896 shading units and 32 ROPs. Its boost clock of 1665 MHz and base clock of 1485 MHz are modest by modern standards, and the FP32 performance of 2.984 TFLOPS reflects its entry-level positioning.

The benchmark results show a clear pattern: as resolution increases, the average FPS drops sharply, which is the classic signature of a GPU-limited scenario. Moving from 1080p High (69.7 FPS) to 1440p High (46 FPS) represents a 34% reduction, and further to 4K High (23.8 FPS) shows another 48% reduction. The GTX 1650's DirectX 12 score of 35 in Passmark and its Vulkan score of 35966 in Geekbench indicate it handles modern APIs, but its raw throughput is insufficient for higher workloads. The card's 75 W TDP and lack of power connectors mean it runs efficiently, but efficiency does not translate into performance here. The GPU's percentile rank of 43 places it below most dedicated gaming cards, and the measured data confirms it cannot sustain high frame rates in Doom beyond 1080p Low.

CPU Role

The AMD Ryzen 7 5800X is vastly overqualified for this pairing. With 8 cores and 16 threads based on the Zen 3 architecture (Vermeer), the CPU operates at a base clock of 3.80 GHz and boosts up to 4.70 GHz. Its 32 MB of L3 cache and support for DDR4 memory at 51.2 GB/s bandwidth provide exceptional processing capability. The CPU's benchmark scores are strong across the board: a Cinebench R23 multicore score of 23571 and a single-core score of 3327, with a Geekbench multicore score of 10220 and single-core of 2194.

In this game, the CPU's role is minimal because the GTX 1650 cannot feed it enough frames. The CPU's nearest rivals include the AMD Ryzen 7 5800 (0.3% higher average score) and the Intel Core i5-12600KF (-0.8% lower), indicating the 5800X is well within the expected performance envelope for its class. However, none of that matters when the GPU is the limiting factor. The data shows that at 1080p Low, the combination achieves 92.7 FPS, which is likely near the practical ceiling for this GPU. The CPU could easily push well over 200 FPS in Doom if paired with a stronger GPU, but with the GTX 1650, the CPU sits largely idle, waiting for the graphics card to catch up. The 5800X's 105 W TDP and multi-threaded performance are wasted in this context.

How This Combo Ranks

The combo rank of 1600 out of 1681 tested combinations places this system in the bottom 5% of all tested configurations for Doom. This ranking is a direct consequence of the GPU's limitations. The GTX 1650's nearest rivals include the AMD Radeon 550X (-0.4% delta) and the NVIDIA Quadro P2200 (0.5% delta), which are all similarly positioned near the bottom of the performance spectrum. The CPU, by contrast, ranks in the 84th percentile, meaning it is in the top 16% of all processors tested.

The data indicates that this pairing is severely imbalanced. The CPU is capable of driving high-end graphics cards, but the GPU cannot deliver playable frame rates at higher settings. In a game like Doom, which is known for its optimized id Tech engine, the combination still struggles. The rank of 1600 suggests that nearly every other tested combo, even those with older CPUs, performs better because they likely pair them with more capable GPUs. This is a cautionary tale about pairing a high-end CPU with an entry-level GPU; the CPU's potential is entirely untapped.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals the GPU bottleneck clearly. At Low settings, the average FPS drops from 92.7 at 1080p to 60.8 at 1440p, a 34% reduction, and then to 30.8 at 4K, another 49% reduction. This steep decline is typical of a GPU that is limited by memory bandwidth and fill rate. At Medium settings, the drop is similar: 79.4 FPS at 1080p, 52.7 FPS at 1440p, and 29.7 FPS at 4K. High settings show 69.7 FPS at 1080p, 46 FPS at 1440p, and 23.8 FPS at 4K.

The pattern is consistent: each resolution doubling roughly halves the frame rate, which is the expected behavior when the GPU is the limiting component. The CPU's performance does not scale with resolution, so the fact that FPS drops so predictably confirms the GPU is saturated. At 4K, even Low settings cannot maintain 30 FPS (30.8 FPS), indicating the GTX 1650 is not viable for 4K gaming in this title. The 1080p to 1440p transition is the most playable range, but only at Low or Medium settings. The data suggests that 1080p is the only resolution where this combo provides an acceptable experience, and even then, users must compromise on settings.

Measured FPS Breakdown

The complete measured FPS data for this combination in Doom is as follows:

At 1920x1080, the average FPS by settings preset is: Low at 92.7 FPS, Medium at 79.4 FPS, High at 69.7 FPS, and Ultra at 55.2 FPS. This is the only resolution where any preset exceeds 60 FPS, with Low and Medium both clearing that threshold.

At 2560x1440, the results are: Low at 60.8 FPS, Medium at 52.7 FPS, High at 46 FPS, and Ultra at 34.9 FPS. Only Low maintains a 60 FPS average, and every other preset falls below that mark.

At 3840x2160, the results are: Low at 30.8 FPS, Medium at 29.7 FPS, High at 23.8 FPS, and Ultra at 20.4 FPS. No preset at this resolution achieves a playable frame rate, and the differences between presets are small, confirming the GPU is fully saturated.

The delta between Low and Ultra at 1080p is 37.5 FPS, while at 4K, the delta narrows to just 10.4 FPS. This narrowing at higher resolutions indicates that the GPU's compute and memory limits dominate, making settings adjustments less impactful. The data shows that for a playable experience, users must stick to 1080p and choose between Low (92.7 FPS) and Medium (79.4 FPS), with High being a borderline option at 69.7 FPS. Ultra should be avoided entirely, as it drops below 60 FPS even at 1080p. This combination is best suited for 1080p gaming with modest settings, and users should not expect to push resolutions or visual quality higher.
