Doom

The AMD Ryzen 5 5600X and AMD Radeon RX 7600 XT combination delivers a solid 1080p and 1440p experience in Doom, but 4K performance demands significant settings compromises. The measured frame rates reveal a system that is clearly GPU-bound at higher resolutions, while the CPU’s strong single-thread capabilities keep minimum performance in check.

Resolution Scaling

The frame rate scaling from 1080p to 4K clearly identifies the GPU as the primary bottleneck as resolution increases. At 1080p High settings, the combo produces 147.5 FPS, which drops to 96 FPS at 1440p and further to 53.2 FPS at 4K. This represents a 64% reduction in frame rate when moving from 1080p to 4K, a steep decline that points to the RX 7600 XT being fully saturated at the higher pixel counts.

The scaling pattern becomes even more telling when examining Low settings. At 1080p Low, the system achieves 197.3 FPS, which is an extremely high frame rate that suggests the CPU is still capable of pushing more frames if the GPU could keep up. However, at 4K Low, performance drops to 70.3 FPS, a 64% reduction from the 1080p figure. This consistent drop across all settings levels indicates that the RX 7600 XT's rendering pipeline, rather than any CPU limitation, is the determining factor at 4K.

The gap between Low and Ultra settings widens substantially at higher resolutions. At 1080p, the difference between Low (197.3 FPS) and Ultra (121.8 FPS) is 75.5 FPS. At 4K, the same settings gap is 29.4 FPS, with Ultra producing only 40.9 FPS. This compression at 4K shows that the GPU is so heavily loaded that even reducing graphical fidelity cannot fully compensate for the resolution demands. The 1440p results sit in a comfortable middle ground, with High settings delivering 96 FPS, which remains playable on high-refresh-rate displays.

How This Combo Ranks

The combination ranks 1114 out of 1681 tested CPU-GPU pairings in Doom, placing it in the lower-middle portion of the database. This ranking reflects the RX 7600 XT's position relative to other GPUs, as the card sits at the 63rd percentile among all GPUs. The CPU, conversely, performs much better in general benchmarks, ranking at the 78th percentile among all CPUs.

The GPU's nearest rivals in synthetic benchmarks provide context for this ranking. The RX 7600 XT scores 20,146 in average benchmark score, which is only 0.6% behind the non-XT RX 7600 (20,258). It sits 1.9% ahead of the NVIDIA GeForce RTX 2060 SUPER (19,774) and 1.9% behind the RTX 3070 Mobile (20,534). This tight grouping suggests the 7600 XT is competitive with these cards, but none of them are top-tier performers in modern titles.

The CPU side shows a similar clustering. The Ryzen 5 5600X scores 20,680 on average, which is just 0.3% behind both the Ryzen 5 5600GT (20,740) and the Intel Core i7-10700 (20,746). It trails the Core i5-12490F (20,794) by 0.5% and leads the Intel Xeon 6325P (20,538) by 0.7%. These negligible percentage differences indicate that the 5600X is not holding back the system in this game, as its performance is squarely in line with its direct competitors.

GPU Role

The AMD Radeon RX 7600 XT is built on the RDNA 3.0 architecture with the Navi 33 chip, manufactured on a 6 nm process by TSMC. The card features 16 GB of GDDR6 memory on a 128-bit bus, providing 288.0 GB/s of bandwidth. This memory configuration is notably generous for the card's performance class, which helps explain why the card maintains playable frame rates at 4K even if it cannot reach high refresh rates.

The GPU's clock speeds are substantial, with a base clock of 1980 MHz, a game clock of 2470 MHz, and a boost clock of 2755 MHz. These high clocks, combined with 2048 shading units and 64 ROPs, yield a pixel rate of 176.3 GPixel/s and a texture rate of 352.6 GTexel/s. The FP32 performance of 22.57 TFLOPS places the card in a competitive position for rasterization-heavy titles like Doom.

The card's power characteristics include a 190 W TDP and a single 8-pin power connector, with a suggested PSU of 450 W. The PCIe 4.0 x8 interface is sufficient for this performance level. The 16 GB VRAM capacity is particularly relevant for 4K gaming, as it prevents memory-related stuttering that can occur with 8 GB cards in demanding scenes, even if the raw compute power cannot always maintain high frame rates at that resolution.

Measured FPS Breakdown

At 1920x1080, the system delivers consistently high frame rates across all settings. Low settings produce 197.3 FPS, Medium 173.3 FPS, High 147.5 FPS, and Ultra 121.8 FPS. These numbers indicate that the combo is well-suited for 1080p gaming, with even the most demanding Ultra preset remaining comfortably above 120 FPS.

At 2560x1440, performance remains strong but shows the GPU beginning to strain. Low settings deliver 127.5 FPS, which drops to 111.5 FPS on Medium and 96 FPS on High. Ultra settings fall to 75.5 FPS, which is still playable but marks a clear threshold where high-refresh-rate monitors will not be fully utilized.

The 3840x2160 results reveal the limits of this combination. Low settings produce 70.3 FPS, Medium 59 FPS, and High 53.2 FPS. Ultra settings drop to 40.9 FPS, which is borderline playable but not ideal for a fast-paced FPS. The 4K results show a clear pattern: the RX 7600 XT can handle 4K with reduced settings, but users targeting Ultra quality at this resolution should look elsewhere.
