Doom

Resolution Scaling

The measured frame rates across the three resolutions reveal a classic GPU-bound scaling pattern for this combination. At 1080p High, the system delivers 218.8 FPS, which drops to 143.8 FPS at 1440p and further to 79.7 FPS at 4K. The percentage declines are steep: moving from 1080p to 1440p reduces performance by approximately 34%, while the jump from 1440p to 4K costs another 45% of the frame rate. This steep falloff indicates that the NVIDIA GeForce RTX 3080 is the primary limiting component as pixel count rises.

The Low preset tells a similar story but with higher absolute numbers. At 1080p Low, the system reaches 304.1 FPS, falling to 194.9 FPS at 1440p and 104.2 FPS at 4K. The relative scaling is nearly identical to High, which suggests that even at the lowest settings, the GPU remains the bottleneck. The gap between Low and High at each resolution is consistent: roughly 85 FPS at 1080p, 51 FPS at 1440p, and 24.5 FPS at 4K. This consistent delta indicates that the CPU is not becoming a constraint even at high frame rates; the scaling is entirely driven by GPU workload.

The Ultra preset shows the most dramatic drop. At 1080p Ultra, the system produces 179 FPS, which falls to 117.1 FPS at 1440p and 63.8 FPS at 4K. The 4K Ultra result is the only measured configuration below 60 FPS, sitting at 63.8 FPS. This suggests that the RTX 3080's 10 GB GDDR6X memory and 760.3 GB/s bandwidth are adequate for most configurations but begin to show strain at the highest settings and resolution. The fact that the 4K Ultra score is roughly half of the 1080p High score underscores how resolution scaling amplifies the GPU's workload in this id Tech engine.

The data indicates that this pairing is well-balanced for 1440p gaming, where the High preset delivers 143.8 FPS — comfortably above typical high-refresh displays. At 1080p, the system is massively overprovisioned for most users, with even the Ultra preset exceeding 170 FPS. The 4K results are playable but require careful settings selection, as the gap between Ultra (63.8 FPS) and High (79.7 FPS) is substantial.

CPU Role

The AMD Ryzen 5 5500 is a 6-core, 12-thread processor based on the Zen 3 architecture, running at a base clock of 3.60 GHz and a boost clock of 4.20 GHz. Its benchmark profile shows strong multi-threaded performance: a Cinebench R23 multi-core score of 16429 and a single-core score of 2319. The PassMark multi-thread score of 19330 and single-thread score of 3058 place the chip in the 79th percentile of all CPUs. These synthetic results suggest a processor that can handle high frame-rate gaming without becoming the limiting factor.

In Doom, a title known for its efficient id Tech engine, the CPU's role is primarily to feed the GPU with draw calls and physics calculations. The measured frame rates show no signs of CPU saturation even at 1080p Low, where the system reaches 304.1 FPS. Had the CPU been the bottleneck, we would expect to see a plateau in frame rates as resolution decreases or settings are lowered. Instead, the frame rates continue to climb steeply from 4K to 1080p, indicating that the Ryzen 5 5500 has ample headroom.

The processor's 16 MB of L3 cache and 51.2 GB/s memory bandwidth are sufficient for the game's data streaming requirements. The 3dmark scores are also instructive: the single-thread score of 836 and 2-thread score of 1645 suggest that the chip's single-core performance is competitive, which matters for games that rely heavily on a few threads. The nearest rival, the Intel Core i5-12500, shows an average score delta of -0.1%, indicating near-identical synthetic performance. This parity in CPU benchmarks aligns with the observed gaming results, where the processor does not appear to constrain the GPU.

The Ryzen 5 5500's 65 W TDP and PCIe Gen 3 interface are not performance liabilities in this context. While the RTX 3080 supports PCIe 4.0, the Gen 3 link does not meaningfully impact frame rates in a game like Doom at these settings. The data suggests that the CPU is a capable partner for the RTX 3080, providing enough throughput for the GPU to operate at its full potential across all tested resolutions.

GPU Role

The NVIDIA GeForce RTX 3080 is the dominant component in this pairing, and the benchmark results reflect its Ampere architecture's strengths. The GPU's 8704 shading units, 272 texture mapping units, and 96 ROPs are backed by 10 GB of GDDR6X memory on a 320-bit bus, delivering 760.3 GB/s of bandwidth. The boost clock of 1710 MHz and FP32 throughput of 29.77 TFLOPS give it substantial raw compute power. These specs translate into the high frame rates observed, particularly at 1440p and 1080p.

The GPU's 80th percentile ranking among all GPUs is corroborated by its PassMark G3D score of 25086 and 3DMark Steel Nomad DX12 score of 4407. The nearest rival, the AMD Radeon RX 7900 GRE, shows a delta of -0.9%, which is within noise for synthetic benchmarks. In Doom, the RTX 3080's performance is clearly GPU-bound at all resolutions, as evidenced by the consistent scaling patterns described earlier.

The VRAM capacity of 10 GB is sufficient for this game's demands. The fact that 4K Ultra produces 63.8 FPS while 4K High yields 79.7 FPS suggests that the Ultra preset likely increases texture detail and shadow complexity, which taxes both the memory subsystem and the compute units. The 68 RT cores and 272 tensor cores are not explicitly utilized by Doom's standard renderer, but the GPU's raw rasterization throughput is what drives the observed results.

The memory clock of 1188 MHz (19 Gbps effective) provides the bandwidth needed for high-resolution textures without causing a noticeable bottleneck. This is evident in the relatively small performance gap between 1440p and 4K for the High preset (143.8 vs 79.7 FPS), which is more attributable to pixel fill rate than memory limitations. The GPU's 164.2 GPixel/s pixel rate and 465.1 GTexel/s texture rate are well-matched to the game's resolution scaling demands.

How This Combo Ranks

The combination of the AMD Ryzen 5 5500 and NVIDIA GeForce RTX 3080 ranks 520th out of 1681 tested combos for Doom. This places the pairing in the top 31% of all configurations tested, which is a strong result given that the CPU is a mid-range desktop part. The ranking reflects the fact that the GPU carries most of the performance weight, while the CPU provides sufficient support without dragging down the overall score.

The percentile rankings of the individual components support this interpretation. The CPU sits in the 79th percentile of all CPUs, while the GPU is in the 80th percentile of all GPUs. The combo's rank of 520 out of 1681 suggests that the pairing is well-balanced, as neither component is drastically underpowered relative to the other. The data shows that the GPU is the limiting factor in most scenarios, which is desirable for gaming performance because it means the system can scale settings and resolution without hitting a CPU wall.

Relative to other combos, this pairing outperforms configurations that might pair the RTX 3080 with weaker CPUs, as the Ryzen 5 5500's single-thread and multi-thread scores (Cinebench R23 single-core 2319, multi-core 16429) are sufficient to avoid bottlenecking. Conversely, it would likely underperform against combos that pair the RTX 3080 with higher-end CPUs like the Ryzen 7 or Core i7 series, but those differences would be most pronounced at 1080p Low where the frame rates are highest. The 520th rank indicates that this is a solid mid-to-upper tier configuration for Doom, capable of delivering excellent frame rates at 1440p and playable performance at 4K with the right settings.

Settings Recommendations

Based on the measured frame rates, the High preset at 1440p offers the best balance of visual fidelity and performance, delivering 143.8 FPS. This is sufficiently above 120 FPS to take advantage of high-refresh-rate displays while maintaining the visual quality that the game's engine is known for. The Medium preset at 1440p yields 172.4 FPS, which may be preferable for competitive play where frame rate is prioritized over visual detail.

For 4K displays, the High preset at 79.7 FPS is the recommended choice, as it provides a smooth experience on standard 60 Hz monitors with room to spare. The Ultra preset at 4K drops to 63.8 FPS, which is technically playable but leaves little margin for demanding scenes. The Low preset at 4K produces 104.2 FPS, which is excessive for most 4K displays and sacrifices too much visual quality for the marginal benefit.

At 1080p, the Ultra preset at 179 FPS is the best option for users with high-refresh-rate 1080p monitors, as it provides the highest visual quality while still exceeding 144 Hz. The Medium preset at 259.6 FPS is overkill for most displays and would be unnecessary unless targeting extreme refresh rates. The Low preset at 304.1 FPS is only relevant for esports scenarios where maximum frame pacing is critical.

The data shows diminishing returns from Medium to Ultra at each resolution. At 1440p, the jump from Medium to High costs 28.6 FPS (from 172.4 to 143.8), while the jump from High to Ultra costs another 26.7 FPS (from 143.8 to 117.1). The visual improvements from Medium to High are typically more noticeable than from High to Ultra, making High the sweet spot. For users who prioritize frame rate above all else, Medium at 1440p or 1080p provides excellent performance with only minor visual compromises.
