Doom

The AMD Ryzen 5 7600X paired with the NVIDIA GeForce RTX 4090 is a top-tier combination for Doom, landing at rank 28 out of 1,681 tested combos. This places the pairing in the top 1.7% of all systems tested, reflecting an exceptionally high-performance match for this title. The result is unsurprising given that both components are among the most powerful in their respective categories, but the data confirms that this specific pairing extracts near-maximum performance from the game engine. The combination’s standing confirms the CPU’s strong single-thread performance and the GPU’s overwhelming rasterization power, which together eliminate almost any conceivable bottleneck at standard gaming resolutions.

How This Combo Ranks

The combo’s rank of 28 out of 1,681 tested configurations places it in the 98th percentile of all tested systems for Doom. This is a remarkable achievement, as it outpaces the vast majority of alternatives by a wide margin. The data indicates that the Ryzen 5 7600X, while not the absolute fastest CPU available, provides sufficient headroom for the RTX 4090 to operate at its full potential in this game. The CPU’s average benchmark score of 26,272 places it in the 83rd percentile of all CPUs, while the GPU’s average score of 66,473 puts it in the 91st percentile of all GPUs. This synergy is critical, as Doom is a fast-paced FPS that demands high frame rates, and the measured results show the pairing delivers consistently.

When examining the CPU’s nearest rivals, the performance delta is negligible. The AMD Ryzen 7 PRO 6850U, AMD Ryzen 7 7735U, and AMD Ryzen 5 PRO 5655GE all score within 0.2% of the 7600X, with deltas of 0%, -0.1%, and -0.2%, respectively. The AMD Ryzen 7 5700X is a mere 0.2% ahead. This clustering indicates that, for Doom, the CPU’s specific model matters less than its architectural efficiency, and the 7600X’s Zen 4 cores are more than adequate. For the GPU, the nearest rivals are professional workstation cards like the Tesla T4, Tesla P40, and Quadro P6000, which score within 1.3% of the RTX 4090; however, these are not gaming-focused products and lack the consumer-grade driver optimizations that benefit Doom. The RTX 4090’s sheer compute throughput, measured at 82.58 TFLOPS FP32, ensures it dominates any gaming workload.

GPU Role

The NVIDIA GeForce RTX 4090 is the dominant force in this combination, equipped with 24 GB of GDDR6X memory on a 384-bit bus, delivering a bandwidth of 1.01 TB/s. This memory configuration is far beyond what Doom requires, ensuring that texture streaming and high-resolution rendering are never bottlenecked by memory capacity or speed. The GPU’s base clock is 2235 MHz, with a boost clock of 2520 MHz, and a memory clock of 1313 MHz (21 Gbps effective). These clocks allow the GPU to maintain high utilization even at 4K, where the pixel rate of 443.5 GPixel/s and texture rate of 1,290.2 GTexel/s come into play.

In Doom, the GPU’s role is paramount, as the game is heavily reliant on raw fill rates and shader performance. The measured FPS at 4K Ultra (94.9 avg) versus 4K High (115.9 avg) shows a 21 FPS drop, indicating that the Ultra preset introduces significant GPU load. However, the GPU still manages to push frame rates well above 60 FPS at all tested settings at 4K, which reflects its power. The data shows that the RTX 4090 is never the limiting factor until the highest settings are enabled, and even then, it only begins to show strain. The GPU’s 16,384 shading units and 512 texture mapping units provide the parallel compute necessary to handle Doom’s particle effects and dynamic lighting without breaking a sweat. The 128 RT cores and 512 tensor cores are present, but Doom does not heavily utilize ray tracing, so the rasterization performance is the primary driver of these results.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target refresh rate and resolution. At 1080p, the Low preset yields an average of 431.2 FPS, which is excessive for most displays, while the Ultra preset still delivers a staggering 267.1 FPS. For high-refresh-rate 1080p monitors (240Hz or higher), the High preset at 329.8 FPS is a balanced choice, offering a significant visual upgrade over Low with only a 23% FPS reduction. The Medium preset at 388.9 FPS is also viable, but High provides a better visual experience per frame.

At 1440p, the High preset delivers 209.6 FPS, which is ideal for 144Hz and even 165Hz displays. The Ultra preset drops to 170.3 FPS, which is still playable but begins to push the GPU harder; however, the visual gains are marginal compared to High. The data suggests that High at 1440p is the sweet spot, offering a 39.3 FPS advantage over Ultra while maintaining visual fidelity. For 4K gaming, the High preset at 115.9 FPS is the best recommendation, as it provides a smooth experience on 120Hz displays. The Ultra preset at 94.9 FPS is playable but may cause noticeable frame drops on higher refresh rate panels. The Medium preset at 136.8 FPS and Low at 155.1 FPS are options for competitive play, but they sacrifice too much visual quality for the modest FPS gain. Overall, High settings at any resolution provide the best balance of performance and image quality for this hardware.

FAQ

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

A: The data shows that 1440p High provides 209.6 FPS, making it ideal for high-refresh-rate monitors. 4K High at 115.9 FPS is also excellent for 120Hz displays, while 1080p High at 329.8 FPS is overkill for most monitors.

*Q: Does the CPU bottleneck the GPU in Doom?*

A: No. The CPU’s single-thread score of 3,406 in Cinebench R23 and its 83rd percentile ranking indicate it has ample headroom. The FPS scaling from 1080p to 4K shows the GPU becomes the limiting factor at higher resolutions, not the CPU.

Q: Is the Ultra preset worth using at 4K?

A: The Ultra preset at 4K yields 94.9 FPS, which is 21 FPS lower than High. Given the minimal visual difference in Doom, the High preset at 115.9 FPS is the better choice for maintaining a smooth experience.

Q: How does this combo compare to other tested systems?

A: It ranks 28th out of 1,681 tested combos, placing it in the top 1.7% of all configurations. This means it outperforms 98% of tested systems in Doom.

Q: Can this combo handle 240Hz gaming?

A: At 1080p, the Low preset hits 431.2 FPS and High hits 329.8 FPS, both well above 240Hz. At 1440p, High at 209.6 FPS is below 240Hz, so you would need to lower settings or resolution to hit that target.

Q: What is the GPU’s memory bandwidth and why does it matter?

A: The RTX 4090 has a 1.01 TB/s bandwidth from its 24 GB GDDR6X memory on a 384-bit bus. This ensures texture streaming is never a bottleneck, especially at 4K where the GPU’s 443.5 GPixel/s pixel rate is fully utilized.

Resolution Scaling

The FPS data reveals a clear scaling pattern across resolutions, indicating a GPU-bound workload. At 1080p High, the combo achieves 329.8 FPS, which drops to 209.6 FPS at 1440p High (a 36% reduction) and further to 115.9 FPS at 4K High (a 65% reduction from 1080p). This steep decline is characteristic of a GPU-limited scenario, as the CPU has sufficient headroom to feed frames at lower resolutions. The RTX 4090’s raw compute power is taxed more heavily as pixel count increases, and the 4K resolution requires four times the pixel throughput of 1080p, explaining the significant FPS drop.

The scaling is not perfectly linear, however. From 1080p to 1440p, the FPS drops by 120.2, while from 1440p to 4K, it drops by 93.7. This suggests that at 1440p, the GPU is still not fully saturated, allowing for a relatively smaller absolute drop compared to the pixel count increase. At 4K, the GPU approaches its limits, and the 94.9 FPS at Ultra indicates it is heavily loaded. The data shows that the limiting component shifts from CPU-bound at 1080p (where FPS exceeds 300 and the CPU’s single-thread performance of 3,406 in Cinebench R23 becomes relevant) to GPU-bound at 4K (where the GPU’s memory bandwidth and pixel rate dominate). At 1080p Low, the 431.2 FPS suggests the CPU is nearing its limit, but the Zen 4 architecture’s high IPC keeps it from becoming a severe bottleneck. Overall, the scaling confirms that the RTX 4090 is the performance driver at higher resolutions, while the Ryzen 5 7600X provides a stable foundation without limiting frame rates at lower settings.
