Doom

The AMD Ryzen 5 2600 paired with the AMD Radeon RX 7600 delivers a remarkably smooth experience in Doom, consistently exceeding 60 FPS at 1440p with High settings and approaching 120 FPS at 1080p on Ultra. The data shows this combination is well-balanced for the title, with the GPU acting as the primary scaling factor across resolutions, while the CPU provides sufficient headroom to avoid bottlenecking in most scenarios.

Settings Recommendations

For the best balance of visual fidelity and performance, the High preset at 2560x1440 is the clear sweet spot for this combo. The measured average of 94.3 FPS at 1440p High is well above the 60 FPS threshold for smooth gameplay, while the jump to 1080p High yields 141.7 FPS—a 50% improvement that suits high-refresh-rate displays. Pushing to Ultra at 1440p drops the average to 76.1 FPS, which is still playable, but the visual gain over High is marginal relative to the 19% performance loss.

At 4K, the situation changes dramatically. The Ultra preset falls to 38.8 FPS, which is below playable standards, while High manages 53 FPS—borderline but not ideal. The Medium preset at 4K produces exactly 60 FPS, making it the only 4K option that reliably hits the 60 FPS target. For players prioritizing frame rate over resolution, the Low preset at 1080p delivers 195.3 FPS, which is exceptional for competitive play, but Medium at 1080p (169.9 FPS) offers a far better visual experience with only a 13% reduction in speed.

How This Combo Ranks

This specific CPU-GPU pairing ranks 1121 out of 1681 tested combinations in Doom, placing it in the 33rd percentile of all configurations. This rank reflects a mid-tier standing, which aligns with the hardware's specifications: the Ryzen 5 2600 sits at the 77th percentile among all CPUs, while the RX 7600 ranks at the 63rd percentile among GPUs. The combo's overall position suggests that while neither component is top-tier, their synergy in Doom produces respectable results that outperform a significant portion of the field.

The ranking gap between the CPU's strong percentile (77) and the combo's overall rank (33rd percentile) indicates that the GPU is the limiting factor in this pairing. The RX 7600's 63rd percentile GPU standing drags the combined score down, yet the result remains competitive because Doom is an older title (released in 2016) that scales well with modern hardware. Notably, the CPU's nearest rival, the Intel Core i5-11600KF, scores 0.6% higher, while the AMD Ryzen 5 7530U trails by 0.6%, showing the 2600 holds its own against newer parts.

GPU Role

The AMD Radeon RX 7600 is built on the RDNA 3.0 architecture with 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s of bandwidth. Its boost clock of 2655 MHz and game clock of 2250 MHz provide substantial compute power, with 2048 shading units and 64 ROPs handling pixel output at 169.9 GPixel/s. The GPU's 21.75 TFLOPS of FP32 performance is the driving force behind Doom's frame rates, particularly at higher resolutions where pixel throughput becomes critical.

The 8 GB VRAM capacity proves sufficient for Doom at all tested settings, as the game's 2016-era engine does not demand excessive memory. The GPU's memory clock of 2250 MHz (18 Gbps effective) and 128-bit bus width create a bandwidth ceiling that becomes apparent at 4K, where the Ultra preset drops to 38.8 FPS. The PassMark G3D score of 16634 and 3DMark Steel Nomad score of 2310 confirm the GPU's mid-range positioning, with the nearest rival, the RX 7600 XT, scoring 0.6% higher on average benchmarks.

Measured FPS Breakdown

At 1920x1080, the RX 7600 delivers exceptional performance across all presets. The Low preset achieves 195.3 FPS, Medium reaches 169.9 FPS, High hits 141.7 FPS, and Ultra maintains 120.1 FPS. These numbers show a consistent scaling pattern: each step up in quality costs roughly 15-20% of performance, with the gap between Low and Ultra totaling 38%. The 120.1 FPS floor at Ultra means even maximum settings remain highly playable on standard 60 Hz or 144 Hz monitors.

Moving to 2560x1440, the performance curve shifts downward but remains strong. Low preset delivers 126.9 FPS, Medium produces 111.5 FPS, High achieves 94.3 FPS, and Ultra drops to 76.1 FPS. The scaling from 1080p to 1440p shows a 26-37% reduction in frame rates depending on preset, with Ultra suffering the largest relative loss. At 1440p, the High preset's 94.3 FPS offers the best compromise, providing near-Ultra visuals with a 24% performance advantage over Ultra.

At 3840x2160, the GPU begins to struggle with higher presets. Low preset yields 70.4 FPS, Medium achieves 60 FPS, High falls to 53 FPS, and Ultra drops to 38.8 FPS. The gap between Low and Ultra at 4K is 45%, significantly larger than at lower resolutions, indicating that the GPU's memory bandwidth and pixel throughput become limiting factors at 4K. The Medium preset's exact 60 FPS average is notable, as it provides a stable baseline for 4K gaming.

Resolution Scaling

The transition from 1080p to 1440p to 4K reveals a clear pattern of GPU-bound scaling. At 1080p High, the combo achieves 141.7 FPS; at 1440p High, it drops to 94.3 FPS (a 33% reduction); and at 4K High, it falls to 53 FPS (a 63% reduction from 1440p). This performance curve closely mirrors the pixel count increase: 1440p has 78% more pixels than 1080p, and 4K has 225% more pixels than 1440p. The FPS losses track this pixel growth almost linearly, confirming the GPU as the primary bottleneck.

The Low preset at 1080p (195.3 FPS) drops to 126.9 FPS at 1440p (35% loss) and then to 70.4 FPS at 4K (45% loss from 1440p). This steeper degradation at higher resolutions suggests that even at Low settings, the RX 7600's 288.0 GB/s memory bandwidth and 128-bit bus cannot keep pace with 4K's pixel demands. The CPU's role becomes secondary here: with a boost clock of 3.90 GHz across 6 cores and 12 threads, the Ryzen 5 2600 maintains sufficient frame pacing, but the GPU's fill rate limits ultimate performance.

CPU Role

The AMD Ryzen 5 2600 features 6 cores and 12 threads based on the Zen architecture, with a base clock of 3.40 GHz and a boost clock of 3.90 GHz. Its 16 MB of shared L3 cache and dual-channel DDR4 memory support with 46.9 GB/s bandwidth provide sufficient data throughput for Doom's engine. The CPU's Cinebench R23 multi-core score of 11186 and single-core score of 1579 place it at the 77th percentile among all CPUs, indicating solid processing power for a 2018-era part.

In Doom, the CPU's role is secondary to the GPU, as evidenced by the scaling patterns across resolutions. At 1080p Low, the 195.3 FPS result approaches the CPU's frame delivery limit, but the 3.90 GHz boost clock keeps pace with the GPU's output. The PassMark multithread score of 13160 and single-thread score of 2239 confirm the CPU can handle the game's physics and AI calculations without introducing stutter. The nearest CPU rival, the Intel Core i5-11600KF, scores 0.6% higher on average benchmarks, while the Intel Core i7-10700F trails by 0.7%, showing the 2600 remains competitive despite its age.

The CPU's 65W TDP and 12 nm process node contribute to efficient operation, but its PCIe Gen 3 interface with 16 lanes may slightly limit the GPU's PCIe 4.0 x8 connection. However, this bandwidth difference does not appear in the measured FPS data, as the combo achieves strong results across all settings. Overall, the Ryzen 5 2600 provides ample headroom for Doom, ensuring the RX 7600 can operate at its full potential without CPU-induced frame drops.
