Doom

The AMD Ryzen 5 7600X paired with the NVIDIA GeForce RTX 3080 delivers a formidable 1080p and 1440p experience in Doom, with performance scaling that reveals a clear shift in bottleneck behavior as resolution increases. This combination ranks in the 70th percentile of all tested combos for this title, indicating a strong, well-balanced pairing that excels at high refresh rate gaming.

Resolution Scaling

Analyzing the measured FPS data across the three tested resolutions shows a classic pattern of GPU-bound scaling, but with a notable CPU headroom at lower settings. At 1080p with Low settings, the combo achieves 302.6 FPS, which drops to 197.2 FPS at 1440p and further to 103.2 FPS at 4K. This represents a 34.8% reduction from 1080p to 1440p, and a 47.7% reduction from 1440p to 4K. The steep drop at 4K indicates that the GeForce RTX 3080's rendering workload becomes the dominant constraint, as the pixel count quadruples from 1080p to 4K.

However, the scaling pattern shifts when examining the Ultra preset. At 1080p Ultra, the combo produces 182 FPS, while 1440p Ultra yields 115.3 FPS, and 4K Ultra drops to 64.3 FPS. The percentage deltas between resolutions are more moderate here, suggesting that the CPU's single-thread performance—evidenced by a 3dmark_single_thread score of 1060 and a cinebench_r23_singlecore score of 3406—remains sufficient to feed the GPU even at lower resolutions. The data shows that the gap between Low and Ultra settings narrows as resolution increases, which is a hallmark of a GPU-limited scenario. At 1080p, the difference between Low (302.6 FPS) and Ultra (182 FPS) is 120.6 FPS, but at 4K, that gap compresses to just 38.9 FPS (103.2 vs 64.3).

This indicates that the Ryzen 5 7600X, with its 6 cores and 12 threads, is not the limiting factor in this title. The CPU's passmark_single_thread score of 4135 places it in the 83rd percentile among all CPUs, and its 3dmark_8_threads score of 5715 shows strong multi-threaded performance for a modern FPS. The bottleneck shifts almost entirely to the GPU at 4K, where the RTX 3080's memory bandwidth of 760.3 GB/s and 10 GB of GDDR6X VRAM are tasked with filling the massive pixel buffer.

How This Combo Ranks

Within the benchmark database's tested combinations for Doom, the AMD Ryzen 5 7600X and NVIDIA GeForce RTX 3080 holds a rank of 508 out of 1681 total combos. This places it in the 70th percentile, meaning it outperforms roughly 70% of all tested systems in this specific title. The ranking reflects the synergy between a high-end 2022 CPU and a high-end 2020 GPU, both of which are now considered previous-generation parts but remain highly capable.

The CPU's nearest rivals in general benchmarks include the AMD Ryzen 7 PRO 6850U and the AMD Ryzen 7 7735U, with delta percentages of 0 and -0.1 respectively, indicating nearly identical average scores. This suggests that in CPU-bound scenarios, the 7600X performs on par with these mobile-oriented chips, though its desktop architecture with a 4.7 GHz base clock and 5.3 GHz boost clock provides consistent sustained performance. The GPU's nearest rivals, including the AMD Radeon Pro Duo and AMD Radeon RX 7900 GRE, show delta percentages of -0.2 and -0.9, placing the RTX 3080 in a competitive position relative to newer AMD parts.

The combo's rank is particularly impressive given that the RTX 3080's production status is listed as end-of-life, yet it still delivers top-tier performance in this title. The data suggests that for Doom specifically, the pairing is well-balanced, with neither component significantly dragging down the other. The 83rd percentile ranking of the CPU and 80th percentile ranking of the GPU relative to their respective categories align well with the combined 70th percentile game rank.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across all resolution and settings combinations. At 1920x1080, the combo delivers exceptional frame rates: 302.6 FPS on Low, 263.1 FPS on Medium, 220.9 FPS on High, and 182 FPS on Ultra. These figures indicate that the system is well-suited for competitive play on high refresh rate monitors, as even the Ultra preset exceeds 144 Hz comfortably.

Moving to 2560x1440, the performance remains strong but shows expected scaling: 197.2 FPS on Low, 172.2 FPS on Medium, 143.8 FPS on High, and 115.3 FPS on Ultra. The High preset at 1440p is particularly notable, as it crosses the 144 Hz threshold, making it ideal for 1440p gaming monitors. The Ultra preset, while lower, still provides a smooth experience above 100 FPS.

At 3840x2160, the combo begins to show its limits. Low settings produce 103.2 FPS, Medium yields 90.8 FPS, High drops to 80.6 FPS, and Ultra falls to 64.3 FPS. While these numbers are still playable, they demonstrate that 4K gaming requires careful settings management. The step from Medium to High at 4K results in a 10.2 FPS penalty, and moving to Ultra costs another 16.3 FPS. The data indicates that the RTX 3080's 10 GB VRAM and 760.3 GB/s bandwidth are sufficient for this game, but the sheer rendering load at 4K Ultra pushes the GPU to its limits.

The consistency of the scaling across settings reflects the CPU's ability to keep up. At no point does the data show a dramatic collapse in performance that would indicate a CPU bottleneck, even at 1080p Low where the frame rate exceeds 300 FPS. The Ryzen 5 7600X's high single-thread performance, evidenced by its 3dmark_single_thread score of 1060 and cinebench_r23_singlecore score of 3406, ensures that the GPU is fed with data efficiently.

GPU Role

The NVIDIA GeForce RTX 3080 is the dominant performance driver in this combo, particularly at higher resolutions. Its Ampere architecture, built on Samsung's 8 nm process with 28,300 million transistors, provides 8704 shading units and 272 texture mapping units. The GPU's boost clock of 1710 MHz, paired with a base clock of 1440 MHz, allows it to reach 29.77 TFLOPS of FP32 performance. This raw compute power is what enables the high frame rates observed at 1080p and 1440p.

The memory subsystem plays a critical role in Doom's performance. The 10 GB of GDDR6X memory operates at 19 Gbps effective, delivering 760.3 GB/s of bandwidth across a 320-bit bus. This bandwidth is essential for texture streaming and frame buffer operations, particularly at 4K where the pixel throughput demands are highest. The data shows that the GPU's memory configuration is not a limiting factor in this title, as even at 4K Ultra, the average FPS remains above 60.

The GPU's 68 ray tracing cores and 272 tensor cores are present, though Doom (released in 2016) does not utilize these features. The DirectX 12 Ultimate API support (12_2) ensures compatibility with modern rendering techniques, but the game's Vulkan support and OpenGL 4.6 compatibility mean it runs efficiently on the RTX 3080's architecture. The passmark_g3d score of 25086 and 3dmark_steel_nomad_dx12 score of 4407 confirm the GPU's strong standing, placing it in the 80th percentile of all GPUs.

The RTX 3080's role becomes increasingly critical as resolution scales. At 1080p, the CPU's headroom is evident, but the GPU still manages to produce over 180 FPS even at Ultra settings. At 4K, the GPU is clearly the bottleneck, with performance dropping by 65-78% depending on settings compared to 1080p. The 320W TDP and suggested 700W PSU indicate the power requirements for sustained performance, but the data shows that the GPU delivers consistent results across all tested scenarios. The combination of high memory bandwidth and substantial compute resources makes the RTX 3080 an excellent match for this game, providing a smooth experience across the board.
