Doom

The AMD Ryzen 7 5700X and AMD Radeon RX 7900 XT combination delivers exceptionally high frame rates in Doom, placing the combo at rank 364 out of 1681 tested combinations. This top-quartile position (roughly the 78th percentile) reflects a pairing that is heavily overqualified for this 2016 title, resulting in performance that is limited more by the game's engine and the selected settings than by the hardware itself. The data shows a system capable of obliterating even the most demanding presets at 4K, with the primary challenge being the massive headroom available at lower resolutions.

How This Combo Ranks

The combo's rank of 364 out of 1681 tested combos places it in the top 22% of all tested system pairings for Doom. This is a strong result, though notably not a top-tier finish, which is telling given the hardware involved. The RX 7900 XT alone sits at the 82nd percentile among all GPUs, while the Ryzen 7 5700X is at the 83rd percentile among CPUs. The fact that this pairing does not crack the top 200 suggests that Doom's performance ceiling is being hit well before the hardware's limits are reached. The benchmark results indicate that this is a case of diminishing returns: the hardware is so fast that the game simply cannot utilize the full potential, making the rank more a reflection of the game's age than a weakness of the components. The RX 7900 XT’s average benchmark score of 38358 is nearly identical to the NVIDIA GeForce RTX 5080 Mobile (38349, a 0% delta), placing it in elite company, yet the in-game rank still leaves room above, confirming that software limitations, not hardware, are the bottleneck.

CPU Role

The Ryzen 7 5700X is a Zen 3 (Vermeer) processor with 8 cores and 16 threads, running at a base clock of 3.40 GHz and a boost clock of 4.60 GHz. For Doom, a game from 2016, this is an overwhelming amount of processing power. The CPU's single-thread performance, as measured by a 3dmark single-thread score of 921, is more than sufficient to feed the GPU. The multi-threaded capability, evidenced by a Cinebench R23 multi-core score of 22620, is largely irrelevant for this title, as Doom's engine does not scale heavily across 16 threads. The data shows that the CPU's role here is to ensure that frame pacing never stutters due to a lack of processing headroom. With a PassMark single-thread score of 3385, the CPU is far beyond the threshold needed to maintain high minimum frame rates. The 32 MB of shared L3 cache helps with game data access, but the primary takeaway is that in this pairing, the CPU is a silent partner, never becoming the limiting factor. Even at 1080p with Low settings, where the CPU load is proportionally highest, the combo still achieves an average of 338.9 FPS, indicating the 5700X is keeping up without breaking a sweat. Its position relative to rivals like the Intel Core i9-11900KF (deltaPct of 0.1%) shows it is competitively matched, but the game's needs are so modest that the difference between these CPUs is imperceptible in Doom.

GPU Role

The AMD Radeon RX 7900 XT is the clear star of this show, and its role is to provide an absurd amount of graphical firepower. With 20 GB of GDDR6 memory on a 320-bit bus delivering 800.0 GB/s of bandwidth, memory capacity and speed are non-issues. The GPU's 5376 shading units and 192 ROPs, running at a boost clock of 2394 MHz, are the core of its performance. The data confirms that the GPU is the primary determinant of frame rates across all tested settings. At 4K Ultra, the GPU is working hard, producing 73.3 FPS, while at 1080p Low, it is barely challenged, hitting 338.9 FPS. The 51.48 TFLOPS of FP32 compute is overkill for a 2016 title, but it ensures that even the most intense particle effects and lighting scenarios in Doom are rendered with massive overhead. The GPU's 82nd percentile ranking and its near-identical average score to the NVIDIA GeForce RTX 5080 Mobile (38349 vs 38358, a 0% delta) confirm it as a top-tier part. Its performance in PassMark's DirectX 12 test (score of 110) is interesting, but the in-game results are what matter most here. The RX 7900 XT is so powerful that the primary differentiator between settings is not smoothness, but the sheer FPS number, with the GPU easily maintaining playable frame rates even at the highest settings in 4K.

Measured FPS Breakdown

The measured FPS data reveals a consistent pattern of overwhelming performance across all resolutions and settings. At 1080p, the lowest tested resolution, the combo delivers staggering numbers. With Low settings, the average FPS is 338.9, which drops to 294.1 on Medium and 247.4 on High. Even at Ultra settings, the average FPS remains a blistering 200.3. At 1440p, the results are equally impressive. Low settings yield 221 FPS, Medium produces 189.8 FPS, High brings 160.4 FPS, and Ultra still manages 133.9 FPS. The most demanding scenario, 4K Ultra, produces an average of 73.3 FPS, which is still well within the range of smooth, competitive play. The 4K High setting yields 87.7 FPS, while 4K Medium provides 103 FPS. The 4K Low setting, at 119.7 FPS, shows that even at the highest resolution, the GPU has enough headroom to nearly double the refresh rate of a standard 60Hz monitor. The scaling from 1080p Low to 4K Ultra shows a drop from 338.9 FPS to 73.3 FPS, a 78% reduction, which clearly maps to the GPU's workload increasing with resolution and graphical fidelity. There are no min or max FPS figures in the data, so the analysis relies on the average frame rates, which are uniformly high and indicate a stable experience.

FAQ

Q: Is this combo overkill for Doom?

A: Yes, the data strongly suggests it is. At 1080p Low, the system averages 338.9 FPS, and even at the most demanding 4K Ultra preset, it maintains 73.3 FPS. These numbers are far beyond what is needed for smooth gameplay, indicating that the hardware is only fractionally stressed by this title.

Q: What is the best resolution to play at with this combo?

A: Based on the measured data, 1440p on High settings offers an excellent balance, delivering 160.4 FPS. This provides a high refresh rate experience with strong visual fidelity. However, 4K is also viable, with High settings yielding 87.7 FPS, which is perfect for a 4K 90Hz display.

Q: How does the CPU compare to its nearest rival?

A: The Ryzen 7 5700X has an average benchmark score of 26214, which is nearly identical to its closest rival, the AMD Ryzen 5 7600X, which scores 26272 (a deltaPct of -0.2%). This means the 5700X is effectively on par with that newer part in synthetic tests, and in Doom, the difference is negligible.

Q: Is the GPU's 20 GB of VRAM necessary for this game?

A: No. Doom from 2016 does not require anywhere near 20 GB of memory. The data shows no performance penalties at any setting, but the large VRAM pool is a future-proofing feature rather than a necessity for this specific title. The 800.0 GB/s of memory bandwidth is also far more than Doom needs.

Q: Will the frame rates be stable enough for competitive play?

A: The average FPS figures are extremely high. At 1080p Low, the system hits 338.9 FPS, and even at 1440p High, it maintains 160.4 FPS. These averages suggest a very consistent experience, as the hardware is not being pushed to its limits, which typically helps with frame time consistency.

Q: What is the single most demanding setting for this GPU?

A: The combination of resolution and settings creates the biggest load. The data shows that moving from 1080p Ultra (200.3 FPS) to 4K Ultra (73.3 FPS) results in a 63% performance drop. This indicates that resolution scaling has a more significant impact than the individual preset level.

Settings Recommendations

For the absolute highest visual fidelity, the Ultra preset is the recommended choice, as it delivers playable frame rates at every resolution. At 1080p, Ultra averages 200.3 FPS, at 1440p it yields 133.9 FPS, and even at 4K it maintains a playable 73.3 FPS. This suggests that players can max out the game's settings without concern. However, for those with high refresh rate monitors (144Hz or higher), the High preset is the optimal choice. At 1440p High, the system produces 160.4 FPS, which is above the 144Hz threshold, and at 1080p High, it hits 247.4 FPS, easily saturating even 240Hz displays. The Medium preset offers a middle ground, but the data shows that the jump from Medium to High costs very little in performance (e.g., 294.1 to 247.4 FPS at 1080p), making High the better value for the visual improvement. The Low preset provides the highest frame rates (338.9 FPS at 1080p), but it is unnecessary given the hardware's capability. The data clearly indicates that the High preset provides the best balance of visual quality and performance, while Ultra is perfectly viable for those prioritizing image quality over raw speed.

Resolution Scaling

The performance drop from 1080p to 4K is steep, confirming that the GPU is the primary workload driver. At High settings, the average FPS falls from 247.4 at 1080p to 160.4 at 1440p (a 35% reduction), and then to 87.7 at 4K (a further 45% reduction from 1440p). This scaling pattern is consistent across all settings. For instance, on Ultra, the FPS goes from 200.3 at 1080p to 133.9 at 1440p (a 33% drop) and then to 73.3 at 4K (a 45% drop from 1440p). The consistent 30-45% reductions between resolution steps indicate that the RX 7900 XT is handling the increased pixel count as expected, with no anomalous bottlenecks. The fact that the 1080p to 1440p drop is smaller than the 1440p to 4K drop suggests that the GPU is still very efficient at 1440p, but begins to feel the pressure of 4K's 8.3 million pixels. This scaling behavior points to the GPU being the limiting component, as the CPU's role does not change with resolution. The CPU's performance is constant, so the frame rate differences are purely a function of the GPU's rendering load. The data shows that the system is heavily GPU-bound at all resolutions, which is the ideal scenario for a gaming PC. The headroom at 1080p is so vast that the game becomes more of a benchmark tool than a gaming experience, while 4K begins to provide a more balanced load, yet still results in high frame rates.
