Doom

The AMD Ryzen 5 7600 paired with the Intel Arc B390 produces a severely GPU-limited experience in Doom, with the combo ranking in the bottom 12% of all tested configurations. The data shows a system where the CPU has ample headroom, but the integrated-class GPU consistently caps performance at every resolution and preset, making it unsuitable for smooth 4K play and only marginally viable at 1080p.

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

The AMD Ryzen 5 7600 is a 6-core, 12-thread processor based on the Zen 4 architecture (Raphael) built on a 5 nm process. It operates with a base clock of 3.80 GHz and a boost clock of 5.10 GHz, with a 65W TDP. This desktop chip features a 32 MB shared L3 cache, alongside 64 KB of L1 and 1 MB of L2 per core, and supports DDR5 memory via a dual-channel interface with 83.2 GB/s of bandwidth.

In synthetic CPU benchmarks, the Ryzen 5 7600 demonstrates strong single-thread and multi-thread capability. Its Geekbench single-core score is 2521, and its multi-core score reaches 13413. Cinebench R23 results show 1852 points single-core and 12735 points multi-core. The processor's 3DMark scores scale from 1938 in the 2-thread test to 6503 in the max-thread test, indicating solid scaling across thread counts. The Passmark single-thread score is 3910, while the multithread score is 27058.

For Doom, a 2016 title that is not heavily multithreaded, the CPU's single-thread performance is the most relevant factor. The 5.10 GHz boost clock and strong IPC from Zen 4 ensure that the CPU is never the bottleneck in this pairing. The data confirms this: even at 1080p Low, where the CPU load is highest relative to the GPU, the system achieves 107 FPS. This is more than double the 4K Ultra result of 22 FPS, showing the CPU can feed frames far faster than this GPU can render them.

The CPU's benchmark percentile of 78 versus all CPUs places it well above average. Its nearest rivals in average benchmark score include the AMD Ryzen 9 6900HX (deltaPct 0.2), the Intel Core i9-11900KF (deltaPct 0.4), and the AMD Ryzen 5 8540U (deltaPct 0.5), all within a fraction of a percent of the 7600's score. This indicates the 7600 is a high-performing part that will not hold back modern games in CPU-bound scenarios; it is the GPU that dictates the low frame rates seen in this dataset.

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

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, manufactured on Intel's 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. The GPU features 1536 shading units, 48 texture mapping units, and 24 raster output units, along with 12 ray tracing cores. Its pixel rate is 60.00 GPixel/s, and its texture rate is 120.0 GTexel/s, with FP32 performance rated at 7.680 TFLOPS.

Crucially, the Arc B390 has no dedicated VRAM. Its memory size, type, bus width, and bandwidth are all listed as "System Shared" or "System Dependent," meaning it relies entirely on shared system memory. This is a fundamental constraint for gaming, as it limits memory bandwidth and capacity compared to discrete graphics cards. The GPU's TDP is 80W, and it uses no power connectors, consistent with its integrated nature.

Benchmark data for this GPU is sparse, with only a single 3DMark Steel Nomad DX12 score of 1482. This score places the Arc B390 in the 9th percentile of all GPUs, indicating very low performance. Its nearest rivals in this benchmark are the NVIDIA GeForce GT 520MX (deltaPct 1.3), the NVIDIA GeForce 800M (deltaPct 1.5), the NVIDIA GeForce GT 625 OEM (deltaPct 2.5), and the NVIDIA GeForce GT 710 (deltaPct 2.7). These are all entry-level or legacy mobile/desktop parts, confirming the Arc B390's position at the very bottom of the performance spectrum.

In Doom, this GPU is the clear limiting factor. The measured FPS shows that even at 1080p Low, the system only reaches 107 FPS. While this is playable, the GPU's performance collapses as resolution and settings increase. The data suggests that the shared memory architecture and low raw throughput prevent the Arc B390 from delivering consistent frame rates at higher loads.

How This Combo Ranks

The combination of the Ryzen 5 7600 and Intel Arc B390 ranks 2580 out of 2930 tested combos in Doom, placing it in the bottom 12% of all systems. This poor ranking is driven entirely by the GPU, as the CPU is a high-end part that would otherwise rank much higher. The data indicates a massive mismatch: a top-tier CPU paired with a bottom-tier GPU yields a system that performs worse than many older, more balanced builds.

The ranking reflects the measured FPS data. At 1080p High, the combo achieves 78 FPS, which is decent, but at 4K Ultra, it drops to 22 FPS, which is unplayable. The system's performance is consistently below what the CPU alone would suggest, as the GPU cannot translate the CPU's capability into high frame rates. The 9th percentile GPU rank versus the 78th percentile CPU rank highlights this imbalance. In practical terms, this combo is only suitable for low-resolution, low-settings gaming, and it fails to deliver a good experience at higher loads.

FAQ

Q: What is the best resolution to play Doom with this CPU/GPU combo?

A: The data shows that 1920x1080 is the only resolution where average frame rates exceed 60 FPS across multiple presets. At 1080p Low, the average is 107 FPS, at Medium it is 93 FPS, and at High it is 78 FPS. At 1440p, only the Low preset (69 FPS) breaks 60 FPS, while 4K never exceeds 37 FPS.

Q: How does the Arc B390 compare to its closest GPU rivals?

A: In the 3DMark Steel Nomad DX12 test, the Arc B390 scores 1482. This is 1.3% higher than the NVIDIA GeForce GT 520MX (1463), 1.5% higher than the GeForce 800M (1460), 2.5% higher than the GeForce GT 625 OEM (1446), and 2.7% higher than the GeForce GT 710 (1443). All of these parts are within a 3% performance delta.

Q: Is the Ryzen 5 7600 CPU a bottleneck for the Arc B390 in Doom?

A: No, the data indicates the CPU is not the limiting factor. The Ryzen 5 7600 has high benchmark scores, including a Geekbench single-core score of 2521 and a Cinebench R23 single-core score of 1852. The frame rates drop consistently as resolution increases (from 107 FPS at 1080p Low to 37 FPS at 4K Low), which is a classic sign of GPU limitation, not CPU limitation.

Q: What is the performance difference between the Low and Ultra presets at 1080p?

A: At 1920x1080, the Low preset averages 107 FPS, while the Ultra preset averages 64 FPS. This represents a 43 FPS drop, or approximately 40% lower performance, when moving from Low to Ultra settings.

Q: Does the combo provide a playable experience at 4K?

A: The data shows that 4K performance is poor. The highest average FPS at 3840x2160 is 37 FPS on Low settings, dropping to 28 FPS on High and 22 FPS on Ultra. None of these average frame rates meet the 60 FPS standard for smooth gameplay.

Q: How does the CPU rank relative to other processors?

A: The Ryzen 5 7600 has an average benchmark score of 26324, placing it in the 78th percentile of all CPUs. Its closest rivals are the AMD Ryzen 9 6900HX (0.2% faster), the AMD Ryzen 7 7435HS (0.3% slower), the Intel Core i9-11900KF (0.4% faster), and the AMD Ryzen 5 8540U (0.5% faster).

Resolution Scaling

The measured FPS data shows a steep performance drop as resolution increases from 1080p to 4K, confirming that the GPU is the primary performance limiter. At High settings, the average frame rate falls from 78 FPS at 1920x1080 to 51 FPS at 2560x1440, and finally to 28 FPS at 3840x2160. This represents a 64% reduction in frame rate from 1080p to 4K.

The pattern is consistent across all settings presets. On Low settings, the system delivers 107 FPS at 1080p, 69 FPS at 1440p, and 37 FPS at 4K. The Medium preset shows 93 FPS at 1080p, 60 FPS at 1440p, and 33 FPS at 4K. Even the least demanding preset at 4K (Low) cannot reach 40 FPS, while the most demanding preset at 1080p (Ultra) still averages 64 FPS.

This scaling behavior indicates that the GPU's rendering throughput is the bottleneck, not the CPU. If the CPU were the limiting factor, frame rates would remain relatively flat across resolutions, as the CPU's workload does not change significantly with resolution. Instead, the dramatic drop in FPS as pixel count increases shows that the Arc B390 simply cannot handle the increased rendering load at higher resolutions. The system is effectively playable only at 1080p, with 1440p being marginal for Low settings, and 4K being unsuitable for any preset.

Settings Recommendations

Based on the measured data, the optimal experience for this combo is at 1920x1080 with the Low preset, which yields an average of 107 FPS. This is the only configuration that approaches high refresh rate territory. The Medium preset at 1080p is also viable, averaging 93 FPS, and offers a better visual balance for those willing to trade some frame rate. The High preset at 1080p drops to 78 FPS, which is still playable but shows diminishing returns.

At 2560x1440, only the Low preset (69 FPS) provides a consistently smooth experience above 60 FPS. The Medium preset at 1440p averages exactly 60 FPS, but this is on the edge of playability, and the High preset falls to 51 FPS. For users prioritizing frame rate over visual fidelity, 1440p Low is the recommended choice at this resolution.

At 3840x2160, no preset delivers an acceptable experience. The best result is 37 FPS on Low, which is below the threshold for smooth gameplay. The Ultra preset averages 22 FPS, which is effectively a slideshow. The data strongly suggests avoiding 4K with this hardware combination.

The Medium preset at 1080p offers the best balance of performance and visual quality, with a 93 FPS average and a minimum of 79 FPS. This ensures that even in demanding scenes, the frame rate stays above 60 FPS. For players who prefer maximum smoothness, the Low preset at 1080p, with its 107 FPS average, is the safest choice. Given the GPU's low percentile ranking (9th) and its proximity to legacy parts like the GT 710, users should expect to play at the lowest settings for the best frame rates.
