Doom

The AMD Ryzen 5 3600 paired with the AMD Radeon RX 7700 XT delivers a high-refresh-rate experience in Doom, with performance scaling that clearly demonstrates where the bottleneck sits. This combination of a Zen 2 six-core processor and an RDNA 3.0 graphics card produces frame rates that range from a playable 56 FPS at 4K Ultra to a blistering 264 FPS at 1080p Low, making it a strong contender for esports-style play in this classic FPS.

Resolution Scaling

The performance drop from 1080p to 4K is substantial and clearly indicates a GPU-bound scenario at higher resolutions. At High settings, the average frame rate falls from 194 FPS at 1920x1080 to 126 FPS at 2560x1440, a reduction of 68 FPS. Moving further up to 3840x2160, the average drops to 68 FPS, meaning the jump from 1080p to 4K alone costs 126 FPS, or roughly 65% of the initial performance.

This scaling pattern strongly suggests that at 1080p and 1440p, the limiting component is the CPU. At 1080p Low, the system produces 264 FPS, which is an extraordinarily high figure that indicates the graphics card is not being fully stressed. The Ryzen 5 3600, with its 6 cores and 12 threads, appears to be the ceiling at these lower resolutions. However, as the resolution increases to 4K, the workload shifts decisively to the RX 7700 XT, which is why frame rates compress to between 56 and 93 FPS depending on the preset.

The most telling data point comes from comparing the Low and Ultra presets at each resolution. At 1080p, the difference between Low (264 FPS) and Ultra (159 FPS) is 105 FPS, a massive gap that shows the graphics card has plenty of headroom. At 1440p, this gap narrows to 68 FPS (171 vs 103), and at 4K it narrows further to 37 FPS (93 vs 56). This progressive narrowing illustrates that the GPU is becoming the primary constraint as pixel count increases, while the CPU's role diminishes.

GPU Role

The AMD Radeon RX 7700 XT is built on the RDNA 3.0 architecture using the Navi 32 chip, manufactured on a 5 nm process at TSMC. It operates with a base clock of 1435 MHz, a game clock of 2171 MHz, and a boost clock of 2544 MHz. These clock speeds, combined with 3456 shading units and 96 ROPs, deliver 35.17 TFLOPS of FP32 compute power.

The memory subsystem consists of 12 GB of GDDR6 memory on a 192-bit bus, providing 432.0 GB/s of bandwidth. The GPU's memory clock runs at 2250 MHz with 18 Gbps effective speed. This configuration is sufficient for Doom at all tested settings, as the maximum 4K Ultra preset still achieves 56 FPS without apparent memory-related stuttering.

The GPU's benchmark performance places it at the 67th percentile among all graphics cards. Its average benchmark score of 22549 is closely matched by its nearest rivals, with the NVIDIA GeForce RTX 2080 scoring 1.5% higher and the AMD Radeon RX 5700 scoring 1.7% lower. This indicates that the RX 7700 XT provides performance comparable to previous generation high-end cards, which is consistent with the measured Doom frame rates.

The texture rate of 549.5 GTexel/s and pixel rate of 244.2 GPixel/s are key metrics for understanding the GPU's fill-rate capabilities in a fast-paced FPS like Doom. These specifications support the high frame rates observed at 1080p and 1440p, where the GPU is not the limiting factor.

Settings Recommendations

For players prioritizing maximum frame rates, the Low preset at 1080p delivers 264 FPS, which is ideal for competitive play on high-refresh-rate monitors. This setting minimizes visual fidelity but maximizes responsiveness, and the data shows it provides the smoothest experience in the measured set.

The Medium preset offers the best balance of performance and visual quality across all resolutions. At 1080p, it achieves 230 FPS with a minimum of 196 FPS, ensuring no noticeable dips. At 1440p, Medium maintains 149 FPS average with a minimum of 127 FPS, which is still well above the 100 FPS threshold for smooth gameplay. Even at 4K, Medium delivers 81 FPS with a minimum of 69 FPS, making it the only preset that combines playable frame rates with moderate visual enhancements at this resolution.

High settings provide a middle ground, with 194 FPS at 1080p, 126 FPS at 1440p, and 68 FPS at 4K. While this preset looks better than Medium, the 4K performance dips below the 70 FPS threshold that many consider the minimum for a fluid experience. Ultra settings are best reserved for 1080p or 1440p, where they achieve 159 FPS and 103 FPS respectively, but at 4K they only manage 56 FPS, which may be too low for sensitive players.

Based on the measured data, the Medium preset provides the most consistent experience across all three resolutions. It offers the only complete frame time data (minimum and maximum), and the variance between its minimum and maximum frame rates is relatively tight, indicating stable performance. For users with 1440p or 4K displays, Medium is the recommended starting point, with adjustments upward for those who prefer visual quality over frame rate.

CPU Role

The AMD Ryzen 5 3600 is a six-core, twelve-thread processor based on the Zen 2 architecture using the Matisse codename. It operates at a base clock of 3.60 GHz and a boost clock of 4.20 GHz, with a 65 W TDP. The CPU supports DDR4 memory in dual-channel configuration, providing 51.2 GB/s of memory bandwidth.

In Doom, the CPU's role is most apparent at 1080p, where frame rates exceed 200 FPS. At this resolution, the graphics card is not the limiting factor, and the CPU's single-thread performance becomes critical. The Ryzen 5 3600's single-core benchmark scores include 696 in 3DMark, 214 in Cinebench R15, 892 in Cinebench R20, and 2124 in Cinebench R23. These scores indicate solid single-thread performance that enables the high frame rates observed at 1080p.

The CPU's multi-threaded performance is also relevant for Doom, which can utilize multiple cores. The processor scores 4605 in 3DMark with 16 threads, 3844 with 8 threads, and 4603 with maximum threads. In Cinebench R23, it achieves 15045 points in multicore testing. These results place the Ryzen 5 3600 at the 71st percentile among all CPUs, with its average benchmark score of 17035 being nearly identical to its nearest rivals.

The cache hierarchy includes 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 32 MB of shared L3 cache. This configuration is well-suited for gaming workloads, as the larger L3 cache helps reduce memory latency. The CPU's memory support for DDR4 with dual-channel configuration provides sufficient bandwidth for the game's data requirements.

At 4K resolution, the CPU's influence diminishes significantly. The frame rates at 4K are almost entirely determined by the GPU, as evidenced by the smaller performance gap between Low (93 FPS) and Ultra (56 FPS) settings. This suggests that the Ryzen 5 3600 has enough processing power to feed the RX 7700 XT at this resolution without becoming a bottleneck. The system's overall ranking of 1396 out of 3712 combos reflects this balanced performance profile, where the CPU provides sufficient headroom for the GPU to operate effectively across all tested resolutions.
