Doom

The AMD Ryzen 5 3600 and NVIDIA GeForce RTX 3080 combination delivers exceptional performance in Doom, placing in the top third of all tested configurations with a combo rank of 1153 out of 3712. The data shows this pairing is heavily GPU-bound at higher settings, but the CPU becomes a limiting factor at lower presets and resolutions, where frame rates exceed what the processor can sustain.

Settings Recommendations

The benchmark results indicate that the High preset at 2560x1440 offers the most balanced experience, delivering 143 FPS average. This represents an 18% improvement over the Ultra preset's 117 FPS while remaining far above the 144Hz refresh threshold that many monitors target. At this resolution, the Medium preset pushes performance to 170 FPS with a minimum of 144 FPS, making it the optimal choice for competitive play where frame consistency matters most.

For 4K gaming, the High preset at 3840x2160 produces 78 FPS average, which is playable but falls short of high-refresh displays. The Medium preset at this resolution yields 92 FPS with a minimum of 78 FPS and maximum of 106 FPS, providing a smoother experience than High while maintaining visual quality. The Ultra preset at 4K drops to 63 FPS, which is below the ideal range for fast-paced FPS action.

At 1920x1080, the High preset achieves 221 FPS average, while Medium reaches 255 FPS with a minimum of 217 FPS. The Low preset at this resolution tops out at 268 FPS. Given that Doom is a fast-paced shooter where frame rate directly impacts responsiveness, the Medium preset at 1080p delivers the best combination of visual fidelity and performance, with the minimum frame rate staying well above 200 FPS.

The Ultra preset provides diminishing returns across all resolutions. At 1080p it drops to 181 FPS, at 1440p to 117 FPS, and at 4K to 63 FPS — representing performance penalties of 29%, 18%, and 19% respectively compared to High settings. For most users, the High preset offers the superior experience, as the visual improvements from Ultra do not justify the substantial frame rate costs.

CPU Role

The AMD Ryzen 5 3600 features 6 cores and 12 threads from the Zen 2 architecture, with a base clock of 3.60 GHz and boost clock of 4.20 GHz. This processor ranks in the 71st percentile of all CPUs tested, with an average benchmark score of 17035. Its nearest rival, the Intel Core i7-1260P, scores 17007, representing a negligible 0.2% difference, while the Intel Core i5-11400 sits 0.2% behind at 17067.

In Doom, the CPU's role becomes apparent when examining frame rates across resolutions. At 1080p with Low settings, the combo produces 268 FPS, but at 1440p Low it drops to 195 FPS, and at 4K Low to 105 FPS. This scaling pattern suggests that at lower resolutions and settings, the CPU cannot feed the GPU fast enough to maintain maximum throughput. The 6-core configuration provides sufficient thread count for Doom's engine, which benefits from multi-threading, but the single-thread performance of 696 in 3dmark_single_thread and 2124 in cinebench_r23_singlecore establishes a ceiling.

The 32 MB of shared L3 cache helps maintain smooth frame pacing, as evidenced by the tight minimum frame rates at Medium settings: 217 FPS at 1080p, 144 FPS at 1440p, and 78 FPS at 4K. These minimums indicate that the CPU can sustain consistent work delivery without stuttering, a critical factor for Doom's fast-paced combat. The processor's 65W TDP and dual-channel DDR4 memory support at 51.2 GB/s bandwidth provide adequate bandwidth for the GPU to receive geometry and draw calls.

How This Combo Ranks

The combination of the Ryzen 5 3600 and RTX 3080 achieves a rank of 1153 out of 3712 tested combos in Doom, placing it in the 69th percentile of all configurations. This ranking reflects the RTX 3080's dominant role in determining performance, as the GPU sits in the 68th percentile of all GPUs with an average benchmark score of 23172.

The CPU's 71st percentile ranking suggests that many lower-tier processors could achieve similar results in Doom, as the game's optimization favors GPU throughput. The combination's rank of 1153 indicates that roughly one-third of tested combos outperform this pairing, primarily those with newer or higher-end CPUs paired with similarly powerful GPUs. However, the RTX 3080's strong compute capabilities — 29.77 TFLOPS FP32 performance — ensure that this combo delivers frame rates that exceed the requirements of most displays at 1440p and remain playable at 4K.

The gap between this combo and higher-ranked configurations likely stems from CPU limitations at lower resolutions. At 1080p Medium, the combo achieves 255 FPS, but higher-ranked combos with faster processors would push beyond this, driven by better single-threaded performance. The 3dmark_2_threads score of 1361 and 3dmark_4_threads score of 2579 indicate moderate multi-threading capability, which aligns with Doom's engine requirements.

Resolution Scaling

The performance scaling across resolutions reveals a clear pattern of GPU dominance at higher settings and CPU limitations at lower settings. From 1080p to 1440p, the frame rate drops by 35% at High settings (221 to 143 FPS), 24% at Low settings (268 to 195 FPS), 33% at Medium (255 to 170 FPS), and 35% at Ultra (181 to 117 FPS). These proportional drops indicate that between 1080p and 1440p, the GPU is the primary scaling factor, with pixel count increasing by 78% while frame rates decrease by roughly one-third.

Moving from 1440p to 4K, the performance drops become more pronounced. At High settings, frame rate falls 45% (143 to 78 FPS), while at Low settings it drops 46% (195 to 105 FPS). Medium settings show a 46% decrease (170 to 92 FPS), and Ultra drops 46% (117 to 63 FPS). This consistent 45-46% reduction across all settings at 4K strongly indicates that the GPU is now the sole bottleneck, as the CPU's workload remains constant while the GPU must render four times the pixels of 1080p.

The fact that Low settings at 4K (105 FPS) still falls far short of Low settings at 1080p (268 FPS) demonstrates that the RTX 3080's 10 GB of GDDR6X memory and 760.3 GB/s bandwidth are being fully utilized. The GPU's pixel rate of 164.2 GPixel/s and texture rate of 465.1 GTexel/s establish the upper bound for 4K rendering, and the measured results align closely with these theoretical limits. The CPU's impact diminishes entirely at 4K, as even the 6-core, 12-thread Ryzen 5 3600 can feed the GPU faster than it can process frames at this resolution.

GPU Role

The NVIDIA GeForce RTX 3080 serves as the dominant performance driver in this Doom configuration, particularly at higher resolutions. Based on the Ampere architecture with the GA102 chip manufactured on Samsung's 8 nm process, this GPU packs 8704 shading units, 272 texture mapping units, and 96 raster output pipelines. Its 10 GB of GDDR6X memory operates across a 320-bit bus, delivering 760.3 GB/s of bandwidth — a critical resource for Doom's texture-heavy environments.

The GPU's clock speeds of 1440 MHz base and 1710 MHz boost, combined with 68 ray tracing cores and 272 tensor cores, provide substantial compute headroom. Its FP32 performance of 29.77 TFLOPS and FP16 performance of 29.77 TFLOPS (1:1 ratio) indicate balanced compute capabilities that benefit Doom's Vulkan rendering path. The 3dmark_steel_nomad_dx12 score of 4407 places the GPU in the 68th percentile of all GPUs, with an average benchmark score of 23172.

In Doom specifically, the GPU's role becomes evident from the resolution scaling analysis. At 4K, the GPU is the sole limiting factor, with all settings showing consistent 45-46% frame rate drops from 1440p. The RTX 3080's memory bandwidth of 760.3 GB/s proves sufficient for 4K textures, as evidenced by the Medium preset maintaining a 78 FPS minimum at 3840x2160. The GPU's dual-slot design and 320W TDP require the suggested 700W power supply, but the performance data shows this power budget translates directly into high frame rates.

Compared to its nearest GPU rivals, the RTX 3080's average benchmark score of 23172 sits within 0.4% of the NVIDIA P106-100 (23249), AMD Radeon Pro Vega 16 (23250), AMD Radeon RX 6600M (23273), and AMD Radeon R9 M290X (23276). This tight clustering suggests that in synthetic benchmarks, the RTX 3080 performs near the median of its class, but its real-world Doom performance benefits from the game's optimization for NVIDIA hardware and the GPU's high memory bandwidth.
