Doom

# CPU Role

The AMD Ryzen 5 5500X3D brings a 6-core, 12-thread configuration based on the Zen 3 architecture, built on TSMC's 7nm process. The processor runs at a 3.00 GHz base clock and can boost up to 4.00 GHz, with a 105W TDP. Its most distinctive feature is the 96 MB shared L3 cache, a hallmark of the X3D line, which sits alongside 64 KB L1 and 512 KB L2 per core. This large cache is particularly relevant for game performance, as it can hold more of the working set of game data, reducing the need to fetch from system memory.

For Doom, a fast-paced FPS with heavy geometry and texture streaming, the CPU's role is primarily about feeding the GPU with draw calls and maintaining frame pacing. The PassMark physics score of 2282 and single-thread score of 2941 suggest solid, if not class-leading, per-core performance. The multi-thread score of 20363 indicates that the 12 threads are utilized well, but Doom's engine, while scalable, does not rely as heavily on multi-core scaling as some modern titles. The data shows that in this combo, the CPU is likely not the primary bottleneck at higher resolutions, but at 1080p with low settings, its throughput can become a factor.

The CPU's 85th percentile ranking among all CPUs, with an average benchmark score of 37018, places it in a competitive position. Its nearest rivals show how close the field is: the AMD Ryzen 5 5600F scores 36945, a mere 0.2% behind, while the Intel Core Ultra 5 225 is also 0.2% ahead at 36938. The AMD Ryzen AI 7 PRO 450 is 0.2% behind, and the Intel Core i9-12900T is 0.3% behind. This clustering within a few tenths of a percent suggests that the 5500X3D's performance profile is very much in the mainstream sweet spot, and its cache advantage might give it a slight edge in latency-sensitive workloads like game logic, even if the raw aggregate scores are similar.

In the context of Doom, the 6-core/12-thread setup is sufficient, and the data implies that the CPU's large L3 cache helps maintain consistent frame delivery. When the GPU is pushed hard at 4K, the CPU has headroom; at 1080p, the CPU's single-thread performance becomes more relevant. The boost clock of 4.00 GHz is modest by modern standards, but the cache compensates in gaming scenarios. The PassMark integer math score of 60033 and floating-point score of 34511 provide a baseline for compute capability, which is more than adequate for a game like Doom that is optimized for high frame rates.

# GPU Role

The NVIDIA GeForce RTX 5090 is the flagship of the GeForce 50-series, based on the Blackwell 2.0 architecture and the GB202 chip, fabricated on a 5nm process at TSMC. It packs 92,200 million transistors on a 750 mm² die, with a transistor density of 122.9 million per mm². The GPU operates at a base clock of 2017 MHz and a boost clock of 2407 MHz, with memory clocked at 1750 MHz, achieving 28 Gbps effective. The 32 GB of GDDR7 memory on a 512-bit bus yields a staggering 1.79 TB/s of bandwidth, which is critical for high-resolution textures and heavy geometry.

For Doom, the GPU's role is dominant. The 104.8 TFLOPS of FP32 performance and 1,636.8 GTexel/s texture rate mean the RTX 5090 can brute-force most rendering tasks. The 21760 shading units, 680 TMUs, and 176 ROPs provide a massive amount of parallel processing power. The 170 ray tracing cores and 680 tensor cores are present but less relevant for a 2016 game that does not use ray tracing. The data suggests that the GPU is the primary determinant of frame rates in this combo, especially at higher resolutions.

The GPU's 92nd percentile ranking among all GPUs, with an average benchmark score of 79842, underscores its position at the top of the performance hierarchy. Its nearest rivals are interesting: the NVIDIA Tesla P100 PCIe 16 GB scores 79605, 0.3% behind, and the Tesla P100 PCIe 12 GB is 0.6% behind at 79396. The AMD Radeon RX 6850M XT is 1.1% behind, while the AMD Radeon Pro Vega 64X is 1.4% ahead. These rivals are a mix of datacenter and mobile parts, indicating that the RTX 5090's average benchmark score places it in rarefied air, though not necessarily at the absolute top in synthetic tests.

In Doom, the RTX 5090's 32 GB VRAM is overkill, but the bandwidth ensures that even at 4K Ultra, the GPU can sustain high frame rates. The measured FPS data shows that the GPU is the limiting factor at 4K, as the CPU has enough headroom. The GPU's ability to render at 306 FPS at 1080p Low suggests that it is never truly bottlenecked by the CPU in this title, and the scaling from 1080p to 4K is smooth, indicating a well-balanced system where the GPU's raw power is the star.

# Resolution Scaling

The measured FPS data reveals a clear pattern of resolution scaling that indicates the system's bottleneck shifts as pixel count increases. At 1080p, the average FPS across settings ranges from 256 at Ultra to 306 at Low. The gap between Low and Ultra is 50 FPS, or roughly 19.5% lower performance at Ultra compared to Low. This suggests that at 1080p, the CPU and GPU are both working hard, but the GPU is still the primary driver, as the frame rates are extremely high.

Moving to 1440p, the average FPS drops across the board. At Low, the average is 265 FPS, which is only 41 FPS lower than 1080p Low, a 13.4% decrease. At Ultra, the average is 177 FPS, which is 79 FPS lower than 1080p Ultra, a 30.9% decrease. This indicates that the GPU is becoming more of a bottleneck as resolution increases, but the drop is not linear. The Medium setting at 1440p shows 253 FPS, which is close to the Low setting, suggesting that the GPU handles the extra shading work with minimal penalty.

At 4K, the scaling becomes pronounced. At Low, the average is 159 FPS, which is 147 FPS lower than 1080p Low, a 48% decrease. At Ultra, the average is 96 FPS, which is 160 FPS lower than 1080p Ultra, a 62.5% decrease. This steep drop at 4K Ultra confirms that the GPU is the limiting component. The CPU's role is diminished at this resolution, as the frame rate is constrained by the GPU's ability to fill pixels. The data implies that the CPU has ample headroom at 4K, and the system is GPU-bound.

The implications are clear: at 1080p, the system is balanced, with the CPU able to feed the GPU adequately. At 1440p, the GPU begins to take over as the bottleneck. At 4K, the GPU is the sole limiting factor, and the CPU's 96 MB L3 cache and 6 cores are sufficient to keep up. The data shows that the scaling from 1080p to 4K is not uniform, with the largest percentage drop occurring at Ultra settings, which is expected given the increased shading and texture work.

# How This Combo Ranks

The combo of the AMD Ryzen 5 5500X3D and NVIDIA GeForce RTX 5090 ranks 200th out of 2930 tested combinations in Doom. This places it in the top 6.8% of all combos, which is a strong showing. The percentile ranking indicates that this pairing is well above average, but not at the absolute top. The fact that it ranks 200th suggests that there are 199 combos that achieve higher average FPS in this game, likely involving higher-end CPUs or even more optimized pairings.

The data implies that the RTX 5090 is the dominant component in this ranking, as it is one of the fastest GPUs available. The CPU, while capable, may be holding the combo back from a higher rank. The nearest CPU rivals show that the 5500X3D is within 0.3% of similar processors, so the CPU is not a weak link, but the combo's rank is likely more dependent on the GPU's performance. The fact that the combo ranks 200th out of 2930 means it outperforms 2730 other combinations, which reflects the GPU's power.

The ranking also suggests that there is room for improvement. If the CPU were replaced with a higher-end model, the combo might rank higher, but the data does not show that. The 200th rank is a solid result, and the measured FPS at 4K Ultra (96 FPS) is playable, but not at the highest refresh rates. The combo's ranking indicates that it is a high-performance pairing, but not the absolute best for this game, likely due to the CPU's mid-range positioning.

# Settings Recommendations

Based on the measured FPS data, the best settings for this combo depend on the target resolution and refresh rate. At 1080p, all settings are playable, with Ultra averaging 256 FPS and Low averaging 306 FPS. For a 144Hz or even 240Hz monitor, Ultra at 1080p provides a smooth experience. The Medium setting at 292 FPS is also excellent, but Ultra offers the best visual fidelity with only a 50 FPS penalty over Low, which is negligible at these high frame rates.

At 1440p, the choices become more nuanced. Ultra averages 177 FPS, which is still excellent for high-refresh monitors, and the visual quality is worth the 88 FPS drop from Low. Medium at 253 FPS is a good middle ground if maximum refresh rate is desired. The data suggests that Ultra at 1440p is the sweet spot for this combo, as it balances visual quality with a frame rate that exceeds most gaming monitors' refresh rates.

At 4K, the settings have a significant impact. Ultra averages 96 FPS, which is playable but not ideal for competitive play. High at 117 FPS is a better choice, offering a 21 FPS improvement with only a slight visual downgrade. Medium at 139 FPS is the best balance between quality and performance, as it provides a smooth experience on a 120Hz or 144Hz display. Low at 159 FPS is the highest frame rate but sacrifices the visual quality that the RTX 5090 is capable of. For the best experience at 4K, the data suggests Medium is the recommended preset, as it delivers a high frame rate with decent visual fidelity.
