Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured results for Doom with the AMD Ryzen 5 2600 and Intel Arc B570 reveal a clear and predictable scaling pattern as resolution increases. At 1920x1080 with Low settings, the combo delivers 164 FPS on average. Moving to 2560x1440 drops that figure to 106 FPS, a reduction of 58 FPS or roughly 35%. At 3840x2160, the average falls further to 57 FPS, which is 107 FPS below the 1080p Low result. This scaling behavior is consistent with a system that becomes progressively more GPU-bound as pixel count rises.

The pattern repeats across all settings presets. For High settings, the average FPS at 1080p is 121, at 1440p it is 78, and at 4K it is 42. The percentage drop from 1080p to 4K for High settings is approximately 65%, indicating that the GPU is the primary constraint at higher resolutions. Similarly, Medium settings show 143 FPS at 1080p, 92 FPS at 1440p, and 50 FPS at 4K. Ultra settings produce 99 FPS at 1080p, 64 FPS at 1440p, and 35 FPS at 4K.

The data implies that the Intel Arc B570 is the limiting component at 4K, as the frame rate collapses from playable to marginal. At 1080p, the CPU still has headroom, but the GPU is already being pushed. The scaling from 1440p to 4K is steep: for example, High settings drop from 78 to 42 FPS, a 46% reduction. This suggests that the GPU's compute resources are saturated when rendering Doom at 4K with this preset.

What is particularly telling is the relationship between Low and Ultra at each resolution. At 1080p, Low yields 164 FPS and Ultra yields 99 FPS, a difference of 65 FPS. At 4K, the same comparison shows 57 FPS versus 35 FPS, a difference of only 22 FPS. This narrowing gap indicates that at 4K, the GPU is so heavily loaded that even reducing settings to Low cannot fully compensate for the pixel throughput required. The CPU is not the bottleneck at any resolution tested; the GPU workload dominates.

The measured data also shows that the minimum FPS values at Medium settings scale similarly. At 1080p Medium, the minimum is 121 FPS; at 1440p Medium, it is 79 FPS; and at 4K Medium, it is 43 FPS. This consistency across minimums reinforces the interpretation that the GPU is the limiting factor, as the variance between average and minimum remains proportionally similar.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 2600 is a 6-core, 12-thread processor from the 2000 series, built on the Zen architecture (specifically Zen+ Pinnacle Ridge) using a 12 nm process node. Its base clock is 3.40 GHz with a boost clock of 3.90 GHz. The CPU has a TDP of 65 W and supports dual-channel DDR4 memory with a bandwidth of 46.9 GB/s. In Doom, which is an older title from 2016, the CPU's role is to feed the GPU with draw calls and maintain a stable frame pacing.

The benchmark data shows that this CPU is more than capable of keeping up with the Intel Arc B570 at 1080p. At Low settings, the system reaches 164 FPS on average, which is far beyond typical 60 Hz displays and close to high-refresh monitors. The CPU's 6 cores and 12 threads are sufficient for Doom's engine, which is not particularly demanding on multi-threading. The single-thread performance, as indicated by the Cinebench R15 single-core score of 157.3, is moderate by modern standards, but adequate for this game.

At higher resolutions, the CPU's influence diminishes. The frame rates at 4K are primarily dictated by the GPU, as evidenced by the drop from 57 FPS at Low to 35 FPS at Ultra. The CPU is not the bottleneck; otherwise, we would expect similar frame rates across resolutions for a given setting. Instead, the data shows a clear GPU-bound behavior.

The CPU's benchmark scores place it in the 75th percentile of all CPUs tested, with an average benchmark score of 21484. Its nearest rivals include the Intel Core Ultra 5 228V (deltaPct 0.2%), Intel Core i9-11900H (deltaPct 0.5%), Intel Xeon D-1746TER (deltaPct -0.7%), and AMD EPYC 9454 (deltaPct 1.2%). These rivals are within 1.2% of the Ryzen 5 2600's average score, indicating that this CPU's overall compute capability is competitive with a range of newer and older processors.

In Doom specifically, the CPU's 12 threads are likely underutilized, as the game's engine was designed for the hardware of its era. The boost clock of 3.90 GHz provides adequate single-core performance for the game's physics and AI routines. The data suggests that the Ryzen 5 2600 is not the limiting factor in this combo; the GPU is.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B570 is a discrete GPU from the Battlemage generation, based on the Xe2-HPG architecture. It features 10 GB of GDDR6 memory on a 160-bit bus, providing a bandwidth of 380.0 GB/s. The GPU has a base and boost clock of 2500 MHz, with memory running at 2375 MHz (19 Gbps effective). It includes 2304 shading units, 144 texture mapping units, and 80 raster operation units. The GPU's FP32 performance is 11.52 TFLOPS, and it has a TDP of 150 W.

In Doom, the GPU's 10 GB VRAM is more than sufficient for 4K textures, as the game's requirements are modest by 2025 standards. The memory bandwidth of 380.0 GB/s is adequate for the game's data streaming, but the GPU's raw compute power is what limits performance at higher resolutions. The measured FPS data shows that at 4K, the GPU is the primary constraint.

The GPU's benchmark scores place it in the 65th percentile of all GPUs, with an average benchmark score of 20556. Its nearest rivals include the NVIDIA GeForce RTX 3070 Mobile (deltaPct 0.1%), Intel Arc A750 (deltaPct -0.1%), NVIDIA Quadro M4000M (deltaPct 0.4%), and AMD Radeon R9 M390X (deltaPct -0.5%). These rivals are all within 0.5% of the Arc B570's average score, indicating that this GPU delivers performance comparable to a mobile RTX 3070 and a previous-generation Intel Arc A750.

The GPU's 11.52 TFLOPS of FP32 performance is the key metric for Doom at 4K. The game's renderer scales with pixel count, and the data shows that at 4K Ultra, the combo averages only 35 FPS. This is below the 60 FPS target for smooth gameplay, indicating that the GPU's compute throughput is insufficient for this resolution and preset combination. At 1080p Ultra, the GPU manages 99 FPS, which is acceptable, but the headroom is limited.

The GPU's texture rate of 360.0 GTexel/s and pixel rate of 200.0 GPixel/s are adequate for 1080p and 1440p gaming, but at 4K, the pixel rate becomes a bottleneck. The data supports this: at 4K, even Low settings only achieve 57 FPS, which is barely playable. This suggests that the GPU's fill rate and compute resources are stretched thin at 4K.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of the combo's performance across three resolutions and four settings presets.

1920x1080: At Low settings, the average FPS is 164. Medium settings yield 143 FPS on average, with a minimum of 121 FPS and a maximum of 164 FPS. High settings produce 121 FPS on average. Ultra settings drop to 99 FPS on average. The spread from Low to Ultra is 65 FPS, indicating that the GPU can handle the game at 1080p with headroom.

2560x1440: Low settings average 106 FPS. Medium settings average 92 FPS, with a minimum of 79 FPS and a maximum of 106 FPS. High settings average 78 FPS. Ultra settings average 64 FPS. The spread from Low to Ultra is 42 FPS, which is narrower than at 1080p, suggesting the GPU is becoming more stressed.

3840x2160: Low settings average 57 FPS. Medium settings average 50 FPS, with a minimum of 43 FPS and a maximum of 58 FPS. High settings average 42 FPS. Ultra settings average 35 FPS. The spread from Low to Ultra is 22 FPS, indicating that the GPU is heavily constrained at 4K.

The data shows that the combo is capable of 60+ FPS at 1080p across all settings, and at 1440p for Low and Medium settings. At 1440p High, the average of 78 FPS is still smooth, but Ultra drops to 64 FPS. At 4K, no preset reaches 60 FPS on average; the best is Low at 57 FPS, which is just below the threshold.

The minimum FPS values at Medium settings are worth noting. At 1080p, the minimum is 121 FPS; at 1440p, it is 79 FPS; and at 4K, it is 43 FPS. These minimums indicate that the combo can maintain reasonably consistent frame pacing at lower resolutions, but at 4K, the minimum of 43 FPS suggests occasional stutters or drops.

How This Combo Ranks — use comboRankInGame vs other tested combos

The AMD Ryzen 5 2600 + Intel Arc B570 combination ranks 2332 out of 2930 tested combos in Doom. This places it in the lower-middle tier of all tested configurations. The rank of 2332 out of 2930 means that 798 combos performed worse, and 2331 combos performed better. This is a percentile rank of roughly 20.4%, indicating that this combo is in the bottom fifth of tested systems.

This ranking is somewhat surprising given the individual components' percentile scores. The CPU is in the 75th percentile of all CPUs, and the GPU is in the 65th percentile of all GPUs. However, the combo's rank in Doom is lower, suggesting that the game's performance is not solely determined by raw component power. Doom is a fast-paced FPS that relies heavily on GPU fill rate and CPU single-thread performance, and the combo may be limited by the GPU's 4K performance.

The rank also reflects that many other combos in the database likely include higher-end GPUs or newer CPUs that are better suited to Doom's engine. The combo's 4K performance is particularly weak, with no preset reaching 60 FPS, which drags down its overall ranking. At 1080p and 1440p, the combo is more competitive, but the database's ranking across all resolutions and settings likely weights higher resolutions more heavily.

In comparison to the GPU's nearest rivals, the Arc B570 is closely matched with the RTX 3070 Mobile and Arc A750. However, the combo's rank suggests that the Ryzen 5 2600 may be holding back the GPU in some scenarios, or that the GPU's driver overhead in this specific game is higher than expected. The data shows that the combo is not a top performer in Doom, but it is far from the bottom.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings preset depends on the target resolution and desired frame rate.

For 1920x1080, the Ultra preset offers 99 FPS on average, which is smooth for most monitors. The High preset at 121 FPS provides a better margin for high-refresh displays, while Medium at 143 FPS is excellent for 144 Hz monitors. The Low preset at 164 FPS is best for competitive play where maximum frame rate is prioritized. Given that even Ultra exceeds 90 FPS, the Ultra preset is recommended for visual quality without sacrificing playability.

For 2560x1440, the High preset at 78 FPS is the best balance of visual fidelity and performance. Medium at 92 FPS provides a smoother experience but with lower graphical detail. Ultra at 64 FPS dips below the 70 FPS threshold, which may be noticeable on high-refresh monitors. Low at 106 FPS is the best for frame rate purists, but the visual downgrade is significant. The High preset is recommended for most users, as it maintains a playable frame rate while preserving detail.

For 3840x2160, no preset achieves 60 FPS on average. The Low preset at 57 FPS is the closest, but it sacrifices most graphical enhancements. Medium at 50 FPS is playable but not ideal for fast-paced action. High at 42 FPS and Ultra at 35 FPS are below the threshold for smooth gameplay. If 4K is a requirement, the Low preset is the only viable option, but users should expect occasional dips below 50 FPS. Alternatively, dropping to 1440p High provides a much better experience.

The data suggests that the combo is best suited for 1080p or 1440p gaming. At 1080p, the Ultra preset is recommended for the best visual experience without sacrificing frame rate. At 1440p, High is the sweet spot. At 4K, the combo is not recommended for Doom, as even the lowest settings struggle to maintain a consistent 60 FPS.
