Doom

AMD Ryzen 7 5700 and AMD Radeon RX 7900 XT deliver a formidable Doom experience, one that scales predictably with resolution and settings. This pairing ranks in the top quartile of tested configurations, making it a reliable choice for high-refresh-rate play.

Resolution Scaling

The measured FPS data reveals a clear and consistent pattern: performance degrades smoothly as resolution increases, indicating a well-balanced system where neither component becomes a sudden bottleneck at any tested setting. At 1080p with Low settings, the combo achieves 337.3 FPS. Moving to 1440p drops this to 216.8 FPS, a reduction of roughly 36%, and 4K further reduces it to 116.5 FPS, a 65% drop from the 1080p figure. This scaling is typical for a GPU-bound scenario; the RX 7900 XT has ample headroom at lower resolutions, but pixel throughput demands increase sharply.

The gap between Low and Ultra settings widens with resolution. At 1080p, the difference between Low and Ultra is 132.3 FPS (337.3 vs 205.0). At 1440p, that gap narrows to 86.7 FPS (216.8 vs 130.1). At 4K, the delta shrinks further to 46.4 FPS (116.5 vs 70.1). This trend confirms that the GPU is the primary limiting factor at higher resolutions and settings; the CPU's role diminishes as the render load grows. The data suggests that for competitive play at 1080p, the system is heavily CPU-limited at Low settings, as evidenced by the massive 337.3 FPS figure, but becomes more GPU-dependent as visual fidelity increases.

GPU Role

The AMD Radeon RX 7900 XT is the driving force behind this system's high frame rates. Its 20 GB of GDDR6 memory on a 320-bit bus provides 800.0 GB/s of bandwidth, ensuring that texture streaming and high-resolution assets do not cause stutters. The GPU's boost clock of 2394 MHz, with a game clock of 2025 MHz, allows it to sustain high throughput across all tested scenarios. The RDNA 3.0 architecture, built on a 5 nm process, delivers a substantial 51.48 TFLOPS of FP32 compute, which directly translates to the pixel-crunching ability needed for Doom's fast-paced environments.

Benchmark results place this GPU in the 82nd percentile of all tested graphics cards. Its nearest rival, the NVIDIA GeForce RTX 5080 Mobile, scores nearly identically (38349 vs 38358 average), with a delta of 0.0%. This indicates that the RX 7900 XT's raw rasterization performance is top-tier, even when compared to newer mobile parts. The GPU's 5376 shading units and 192 ROPs are well-suited for the id Tech engine that powers Doom, which favors high fill rates. The data shows that at 4K Ultra, the card still manages 70.1 FPS, which is playable but not ideal for high-refresh-rate monitors; dropping to High settings yields 88.1 FPS, a more comfortable margin.

CPU Role

The AMD Ryzen 7 5700, with its 8 cores and 16 threads, provides a solid foundation for the GPU. Its Zen 3 architecture, running at a base clock of 3.70 GHz and boost clock of 4.60 GHz, ensures that frame pacing remains consistent. The CPU's performance in synthetic benchmarks is strong: it scores 20655 in Cinebench R23 multi-core and 2916 in single-core. This single-thread performance is critical for game logic and draw call submission, and it prevents the CPU from becoming a bottleneck at high frame rates, especially at 1080p.

The CPU ranks in the 84th percentile of all processors, with an average benchmark score of 27220. Its nearest rival, the Intel Core i9-9900K, scores 27043, a delta of just 0.7%. This puts the Ryzen 7 5700 in elite company, though it is notably the data shows no significant CPU bottleneck in this game. At 1080p Low, the system reaches 337.3 FPS, which is likely near the engine's or memory subsystem's limit, but the CPU's 16 MB of L3 cache and dual-channel DDR4 support (51.2 GB/s bandwidth) are sufficient to feed the GPU's demands. The CPU's TDP of 65 W is modest, indicating efficient operation under load.

Settings Recommendations

Based on the measured rows, the optimal balance of visual quality and frame rate depends on the target resolution. For 4K displays, the High preset offers the best experience. It delivers 88.1 FPS, which is a significant improvement over Medium (104.1 FPS) and Ultra (70.1 FPS). The drop from High to Ultra costs 18.0 FPS, a 20% reduction, for what is typically a marginal visual gain in shadow quality and post-processing effects. For 1440p, the High preset at 159.8 FPS is excellent, but Medium at 192.8 FPS provides a substantial boost for competitive play without a major visual sacrifice. The Ultra preset at 130.1 FPS is still smooth, but the data suggests that High is the sweet spot for maintaining high refresh rates.

At 1080p, the choice is more nuanced. High settings yield 250 FPS, which is more than sufficient for any 240Hz monitor. Medium hits 292.4 FPS, and Low reaches 337.3 FPS. Since the difference between High and Low is 87.3 FPS, and High already exceeds the refresh rate of almost all displays, there is little reason to drop below High at this resolution. The Ultra preset at 205 FPS is also viable, though the 45 FPS loss compared to High makes it less attractive for esports-focused users. The data indicates that High is the recommended preset across all resolutions, offering a strong balance of fidelity and performance.

How This Combo Ranks

This specific combination of AMD Ryzen 7 5700 and AMD Radeon RX 7900 XT ranks 377th out of 1681 tested combos in Doom. This places it in the top 22.4% of all configurations, a strong showing for a mid-range CPU paired with a high-end GPU. The ranking reflects the system's ability to deliver high frame rates, but it also highlights that there are faster combinations available, likely pairing the same GPU with newer, higher-clocked CPUs.

The data suggests that the GPU is the primary driver of this ranking. The RX 7900 XT's performance is near the top of the charts, but the Ryzen 7 5700, while competent, does not push the system into the top 10%. The 0.7% delta between the Ryzen 7 5700 and the Intel Core i9-9900K in CPU benchmarks shows that the CPU is not a weak link, but it also does not provide the same headroom as a more powerful processor might in CPU-bound scenarios. For this game, the combo is well-matched, but users seeking absolute maximum FPS at 1080p might see gains from a CPU with higher single-thread performance.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. Low settings produce an average of 337.3 FPS, Medium drops to 292.4 FPS, High to 250 FPS, and Ultra to 205 FPS. The scaling from Low to Ultra is a 39.2% reduction, showing that the GPU is still the main constraint even at this lower resolution.

At 2560x1440, the numbers remain high. Low settings average 216.8 FPS, Medium 192.8 FPS, High 159.8 FPS, and Ultra 130.1 FPS. The transition from 1080p to 1440p results in a 35.7% performance drop at Low settings (337.3 to 216.8 FPS), which is expected given the 77% increase in pixel count. The system remains firmly in high-refresh-rate territory.

At 3840x2160, the GPU is fully taxed. Low settings yield 116.5 FPS, Medium 104.1 FPS, High 88.1 FPS, and Ultra 70.1 FPS. The drop from 1440p to 4K is substantial, with Low settings falling by 46.3% (216.8 to 116.5 FPS). Even at 4K Ultra, the system maintains a playable 70.1 FPS, but High settings are recommended for a smoother experience. The data across all resolutions confirms that this combo is best suited for 1080p and 1440p gaming, where it can fully exploit high-refresh-rate monitors, while 4K requires a compromise on settings to stay above 100 FPS.
