Doom

The AMD Ryzen 5 7600X and NVIDIA GeForce RTX 5080 pairing delivers exceptional performance in Doom, with the data showing a configuration that consistently produces high frame rates across all tested settings. The measured results place this combo in the 51st position out of 1,681 tested combinations, firmly in the upper echelon of the database. Benchmark data indicates this system is well-balanced for the 2016 title, though the scaling patterns reveal distinct roles for the CPU and GPU depending on resolution and quality presets.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 7600X is a 6-core, 12-thread processor from the 7000 series, built on the Zen 4 architecture (codenamed Raphael) using TSMC's 5 nm process. It operates with a base clock of 4.70 GHz and a boost clock of 5.30 GHz, supported by a 32 MB shared L3 cache and 1 MB L2 per core. The chip's single-thread performance is a standout: its 3DMark single-thread score of 1,060 and Cinebench R23 single-core result of 3,406 indicate strong per-core throughput, which directly benefits Doom's engine.

The game's frame rates at 1080p demonstrate how CPU-bound this title becomes at lower resolutions. At 1920x1080 with Low settings, the combo achieves 426.1 FPS, while Ultra settings still deliver 256.8 FPS. These numbers suggest the processor's 12 threads and high boost clock are sufficient to feed the GPU effectively, even at extreme frame rates. The Ryzen 5 7600X scores 6,845 in 3DMark Max Threads and 24,128 in Cinebench R23 multi-core, placing it in the 83rd percentile among all CPUs. Its average benchmark score of 26,272 sits virtually tied with rivals like the AMD Ryzen 7 PRO 6850U (26,262, 0% delta) and the AMD Ryzen 7 7735U (26,305, -0.1% delta), confirming it as a mid-to-high-tier processor that avoids bottlenecking in this title.

Notably, the CPU's dual-channel DDR5 memory support with 83.2 GB/s bandwidth provides ample data throughput for Doom's level streaming. The processor's 105 W TDP and unlocked multiplier allow for sustained boost behavior, which the benchmark results reflect in consistent high averages. The 4-core 3DMark score of 3,796 and 8-thread score of 5,715 indicate that the chip scales well with the game's thread usage, which rarely exceeds 8 threads in this era of the id Tech engine.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 5080 is a Blackwell 2.0 architecture GPU (chip GB203) fabricated on a 5 nm process, with 45,600 million transistors on a 378 mm² die. It features 16 GB of GDDR7 memory on a 256-bit bus, delivering 960.0 GB/s of bandwidth — a figure that becomes relevant at higher resolutions where texture streaming demands grow. The GPU's boost clock of 2617 MHz and base of 2295 MHz, combined with 10,752 shading units, produce 56.28 TFLOPS of FP32 performance.

In Doom, the RTX 5080's role shifts dramatically with resolution. At 4K Ultra, the combo drops to 91.3 FPS, while 1440p Ultra reaches 164.2 FPS and 1080p Ultra hits 256.8 FPS. This pattern indicates the GPU becomes the limiting factor as pixel count rises. The card's 112 ROPs and 293.1 GPixel/s pixel rate handle the game's fill-rate demands, but the Ultra preset at 3840x2160 still requires significant compute. The RTX 5080's average benchmark score of 59,188 places it in the 89th percentile among GPUs, with nearest rivals including the Intel Arc A570M (58,239, 1.6% delta) and Intel Arc Pro A60 (60,326, -1.9% delta).

The 16 GB VRAM capacity is more than sufficient for Doom's 2016-era textures, even at 4K. The memory clock of 1875 MHz (30 Gbps effective) provides the bandwidth headroom that prevents stutter in fast-paced scenes. The GPU's PassMark G3D score of 36,565 and 3DMark Steel Nomad DX12 score of 8,637 show strong raw compute, but the game's performance at 4K (112 FPS High, 91.3 FPS Ultra) suggests the card's architecture is being pushed by the highest settings at this resolution.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear scaling curve that highlights the shift from CPU-bound to GPU-bound behavior. At 1080p Low, the combo produces 426.1 FPS, which drops to 272.3 FPS at 1440p Low (-36.1%) and then 151 FPS at 4K Low (-44.5% from 1440p). This aggressive drop at lower settings indicates the CPU is the primary limiter at 1080p, as the RTX 5080 has ample headroom to render frames faster than the processor can feed it.

At High settings, the scaling is more moderate: 313.4 FPS at 1080p, 204 FPS at 1440p (-34.9%), and 112 FPS at 4K (-45.1% from 1440p). The percentage drops are similar across Low and High, suggesting the game's engine maintains a consistent workload distribution. However, at Ultra settings, the curve steepens: 256.8 FPS at 1080p, 164.2 FPS at 1440p (-36.0%), and 91.3 FPS at 4K (-44.4% from 1440p). The 4K Ultra result of 91.3 FPS represents a 64.5% drop from 1080p Ultra, the largest relative loss among all presets.

This scaling behavior points to the GPU becoming the dominant constraint at 4K, particularly with Ultra settings. The difference between 1080p Low (426.1 FPS) and 1080p Ultra (256.8 FPS) is 39.7%, which is less than the resolution-based drops, reinforcing that the CPU keeps pace until pixel count climbs. The Medium preset shows intermediate results: 370.1 FPS at 1080p, 242 FPS at 1440p, and 131.7 FPS at 4K, with the 4K-to-1080p drop at 64.4% — nearly identical to Ultra's 64.5%.

How This Combo Ranks — use comboRankInGame vs other tested combos

The Ryzen 5 7600X + RTX 5080 combination holds the 51st rank out of 1,681 tested combos in Doom, placing it in the top 3% of all configurations in the database. This ranking is notable given the game's age — it was released in 2016 — and the fact that newer titles often show wider performance gaps between high-end and mid-range systems. The 51st position indicates that this pairing is near the peak of practical performance for this title, with only 50 combinations achieving higher average frame rates.

The rank reflects the synergy between the CPU's strong single-thread performance (83rd percentile among CPUs) and the GPU's high compute throughput (89th percentile among GPUs). Neither component falls below the 80th percentile, which is a key factor in the combo's high placement. The data suggests that combinations ranked above this one likely pair even higher-tier CPUs (potentially with more cores or higher boost clocks) with the same or faster GPUs, but the performance gap is small given the game's engine limitations.

The fact that this combo ranks 51st out of 1,681 means it outperforms the vast majority of systems, including those with older flagship GPUs or slower processors. The delta between this combo and the top-ranked systems is likely minimal in actual frame rate terms, as Doom's engine caps out at certain frame rates due to CPU draw-call limits. The 1080p Low result of 426.1 FPS approaches the practical limits of the game's update loop, suggesting that only a handful of CPUs can push higher.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The complete measured FPS table shows 12 data points across three resolutions and four quality presets. At 1920x1080, the combo delivers its highest frame rates: 426.1 FPS at Low, 370.1 FPS at Medium, 313.4 FPS at High, and 256.8 FPS at Ultra. The spread from Low to Ultra is 169.3 FPS, indicating that the CPU is the primary limiter here — the RTX 5080 can render these frames quickly, but the processor's single-thread speed determines the ceiling.

Moving to 2560x1440, the results are 272.3 FPS (Low), 242 FPS (Medium), 204 FPS (High), and 164.2 FPS (Ultra). The drop from 1080p to 1440p is significant across all settings, averaging about 35.4% reduction. The Ultra preset at 1440p still exceeds 160 FPS, which is smooth for high-refresh-rate monitors. The gap between Low and Ultra at this resolution narrows to 108.1 FPS, showing the GPU beginning to take on more of the workload.

At 3840x2160, the frame rates fall to 151 FPS (Low), 131.7 FPS (Medium), 112 FPS (High), and 91.3 FPS (Ultra). The Low-to-Ultra spread compresses further to 59.7 FPS, confirming that the GPU is now the dominant constraint. The 4K Ultra result of 91.3 FPS remains playable, but it is the only setting below 100 FPS in the entire dataset. The scaling from 1440p to 4K shows a consistent 44-45% reduction across presets, which aligns with the pixel count increase from 3.7 million to 8.3 million pixels.

The data reveals that High settings at 4K (112 FPS) provide a balanced experience, while Low at 1080p (426.1 FPS) demonstrates the absolute ceiling of this combination. For competitive play, the 1440p High result of 204 FPS offers a strong middle ground, while 4K Ultra at 91.3 FPS still delivers a smooth experience for a single-player FPS. The measured results are consistent with the combo's 51st rank, showing no anomalies or frame rate dips that would suggest driver issues or thermal throttling.
