Doom

# How This Combo Ranks

The AMD Ryzen 5 2600 paired with the AMD Radeon RX 7600 XT lands at rank 1059 out of 1681 tested combos in Doom. That places this configuration in the lower-middle tier of the database, roughly in the 37th percentile of all tested systems. The GPU alone sits at the 63rd percentile among all graphics cards, while the CPU holds a 77th percentile ranking among all processors — so the combination underperforms what each component suggests individually.

This gap is telling. The RX 7600 XT's own benchmark average of 20146 closely matches its nearest rival, the AMD Radeon RX 460, which scores 20088 (a mere 0.3% difference). The CPU's average benchmark score of 19616 similarly sits within 0.7% of the Intel Core i7-10700F. Yet in actual Doom gameplay, the pairing's rank suggests the system isn't realizing the full potential of either part. The data implies a bottleneck dynamic where the older Zen architecture CPU limits how much of the GPU's capability gets expressed in this particular title.

GPU Role

The Radeon RX 7600 XT brings substantial memory resources to Doom: 16 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. Its clock speeds are aggressive for a mid-range card — a base of 1980 MHz, a game clock of 2470 MHz, and a boost reaching 2755 MHz. The 2048 shading units, 128 texture mapping units, and 64 raster operation processors provide the raw throughput needed for a fast-paced FPS.

The measured frame rates across resolutions suggest the GPU is rarely the limiting factor at 1080p. At 1920x1080 with Low settings, the combo hits 200.9 FPS average; even at Ultra, it maintains 121.1 FPS. The GPU's 22.57 TFLOPS of FP32 compute and 352.6 GTexel/s texture rate are more than sufficient for Doom's demands at this resolution. The 16 GB VRAM is also far beyond what this 2016 title requires, meaning memory capacity is never a constraint.

However, the picture changes as resolution climbs. The GPU's pixel rate of 176.3 GPixel/s becomes more relevant at 4K, where the card's 64 ROPs must fill twice as many pixels as at 1440p. The data shows the GPU still delivers playable results at 3840x2160 — 52.2 FPS on High — but the frame rate drops accelerate beyond what pure resolution scaling would predict, hinting that the CPU begins to matter more at lower settings where the GPU has headroom.

Resolution Scaling

The measured FPS data reveals how the balance between CPU and GPU shifts across resolutions. Moving from 1920x1080 to 2560x1440 on High settings, average FPS falls from 145.3 to 97.6 — a 32.8% drop. The further jump to 3840x2160 at High brings the average down to 52.2, another 46.5% reduction. These are steep declines, but they follow the expected pattern of pixel-count increases.

The Low settings row tells a more interesting story. At 1080p Low, the system produces 200.9 FPS. At 1440p Low, it drops to 127.8 FPS, and at 4K Low, it reaches 71.3 FPS. The scaling from 1440p to 4K at Low (a 44.2% drop) is nearly identical to the High settings drop (46.5%), which suggests the GPU is becoming the primary constraint at higher resolutions regardless of quality preset. Conversely, the 1080p to 1440p gap at Low (36.4% drop) is smaller than at High (32.8%), implying that at 1080p Low, the CPU is holding the system back from pushing even higher frame rates.

The Ultra preset shows the most dramatic degradation: 121.1 FPS at 1080p, 78.2 at 1440p, and just 44.6 at 4K. The 4K Ultra result is barely above the minimum playable threshold for many gamers, and the gap between 1080p and 1440p Ultra (35.4% drop) is steeper than the High preset's 32.8% drop, indicating that the GPU's shading and texture units are being taxed more heavily by the higher-quality effects.

FAQ

Q: Is the AMD Ryzen 5 2600 bottlenecking the RX 7600 XT in Doom?

A: The evidence suggests yes at lower resolutions. At 1080p Low, the system reaches 200.9 FPS, but the GPU's compute capabilities (22.57 TFLOPS FP32) and the CPU's six cores and twelve threads suggest the CPU is preventing even higher frame rates. The CPU's PassMark single-thread score of 2239 is modest, and Doom's engine often relies on strong per-core performance.

Q: Can this combo handle 4K gaming in Doom?

A: Yes, but with caveats. At 4K High, the average is 52.2 FPS, which is playable. At 4K Medium, it improves to 59.2 FPS, and at 4K Low, it reaches 71.3 FPS. Only the 4K Ultra preset at 44.6 FPS falls below the commonly accepted 60 FPS target.

Q: How does the RX 7600 XT compare to its closest rival in raw GPU benchmarks?

A: The RX 7600 XT scores 20146 on average, while the AMD Radeon RX 460 scores 20088, a difference of just 0.3%. The RX 7600 XT also trails the RX 7600 by 0.6% (20258 vs 20146) but leads the NVIDIA GeForce RTX 2060 SUPER by 1.9% (20146 vs 19774).

Q: What is the best resolution for this combo to maintain high frame rates?

A: At 1920x1080, the system averages 145.3 FPS on High and 174.9 FPS on Medium. At 2560x1440, High delivers 97.6 FPS and Medium hits 115 FPS. For a consistent 100+ FPS experience, 1440p Medium is the sweet spot, while 1080p Ultra (121.1 FPS) also remains viable.

Q: Does increasing settings from Low to Ultra at 1080p cause a proportional FPS drop?

A: No. The drop from Low (200.9 FPS) to Medium (174.9 FPS) is 12.9%, while Medium to High (145.3 FPS) is another 16.9%. The largest jump is from High to Ultra (121.1 FPS), a 16.7% reduction. The total drop from Low to Ultra is 39.7%, which is significant but still leaves the system above 120 FPS.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest performance across all presets. Low settings produce an average of 200.9 FPS, Medium drops to 174.9 FPS, High reaches 145.3 FPS, and Ultra settles at 121.1 FPS. Every preset at this resolution exceeds 120 FPS, making 1080p the most comfortable experience for high-refresh-rate displays.

Moving to 2560x1440, the averages become 127.8 FPS on Low, 115 FPS on Medium, 97.6 FPS on High, and 78.2 FPS on Ultra. The 1440p results show a tighter spread between presets — the difference between Low and Ultra is 49.6 FPS, compared to 79.8 FPS at 1080p. This compression indicates the GPU is becoming more of a limiting factor as resolution increases.

At 3840x2160, the averages are 71.3 FPS on Low, 59.2 FPS on Medium, 52.2 FPS on High, and 44.6 FPS on Ultra. The 4K Low result is noteworthy — it's higher than the 1440p Ultra result (78.2 FPS vs 71.3 FPS), showing that resolution has a larger impact on performance than quality settings. The spread from Low to Ultra at 4K is just 26.7 FPS, the smallest gap across all resolutions, reinforcing that pixel throughput is the dominant constraint.

CPU Role

The AMD Ryzen 5 2600 is a six-core, twelve-thread processor from the 2000 series, built on the Zen architecture (specifically Zen+ Pinnacle Ridge) using a 12 nm process. Its base clock of 3.40 GHz boosts to 3.90 GHz, and it carries 16 MB of shared L3 cache. The CPU's benchmarks show a balanced profile: a Cinebench R23 multi-core score of 11186 and a single-core score of 1579.

In Doom, the CPU's role becomes evident when examining frame rates across resolutions. At 1080p Low, the system produces 200.9 FPS, which is well beyond what most displays can show, but the CPU's single-thread performance (PassMark single-thread score of 2239) may cap the maximum achievable frame rate. The CPU's nearest rivals in average benchmark score include the Intel Core i5-1345U (19691, -0.4% delta), the AMD Ryzen 5 7530U (19508, +0.6%), and the Intel Core i5-11600KF (19740, -0.6%). These comparisons show the 2600 is competitive in general processing, but Doom's engine may favor the newer architectures differently.

The memory bandwidth of 46.9 GB/s (dual-channel DDR4) is another potential factor. At higher resolutions where the GPU is doing more work, CPU memory bandwidth matters less. But at 1080p, where the GPU is underutilized, the CPU's ability to feed draw calls and game logic becomes more critical. The data shows the system still achieves 121.1 FPS at 1080p Ultra, indicating the CPU is not a severe bottleneck but does prevent the GPU from reaching its full potential at lower settings.

Settings Recommendations

For players targeting 60 FPS as a baseline, the 4K High preset (52.2 FPS) falls short, but 4K Medium (59.2 FPS) is just barely under the threshold. The 4K Low preset at 71.3 FPS provides comfortable headroom. At 2560x1440, every preset exceeds 78 FPS, with High (97.6 FPS) and Medium (115 FPS) offering the best balance of visual quality and smoothness.

For the most demanding users with 1080p displays, Ultra settings at 121.1 FPS are entirely playable, and High at 145.3 FPS provides extra headroom for frame time consistency. The data suggests that 1440p Medium is the optimal overall setting — it delivers 115 FPS average while still offering improved visual fidelity over Low settings. The 4K resolution is only recommended with Low settings if a smooth experience is prioritized, as the 71.3 FPS average is the only 4K result that comfortably clears 60 FPS.

The measured rows show diminishing returns from Medium to Ultra at every resolution. At 1080p, the jump from Medium to Ultra costs 53.8 FPS (from 174.9 to 121.1), while at 4K, the same jump costs only 14.6 FPS (from 59.2 to 44.6). This pattern suggests that players on lower-resolution displays can afford to enable higher presets, while 4K users should stick with Low or Medium settings to maintain playable frame rates.
