# Doom: AMD Ryzen 7 5700G + Intel Arc B370 — Benchmark Analysis

The AMD Ryzen 7 5700G paired with the Intel Arc B370 produces a highly constrained gaming experience in Doom, with the combo ranking 2696th out of 2930 tested configurations. The data reveals a system where the integrated-class GPU is the clear bottleneck, as frame rates collapse at higher resolutions while the CPU's 8-core/16-thread Zen 3 architecture remains largely underutilized. This analysis breaks down the measured performance across three resolutions and four quality presets, interprets the scaling patterns, and provides practical guidance based strictly on the observed numbers.

Resolution Scaling

The measured FPS data shows a dramatic and consistent drop as resolution increases from 1920x1080 to 3840x2160, with the scaling pattern indicating the Intel Arc B370 is the limiting component at every step. At 1920x1080 with Low settings, the combo achieves 96 FPS average. Moving to 2560x1440 at the same preset drops that figure to 62 FPS — a reduction of 34 FPS, or roughly 35% lower performance. At 3840x2160 Low, the average falls further to 34 FPS, which is about 45% below the 1440p result and only 35% of the 1080p performance. This steep degradation curve is classic GPU-bound behavior: the rendering load scales with pixel count, and the Arc B370's limited throughput becomes progressively more exposed.

The same pattern holds across all quality settings. For High preset, the transition from 1080p (71 FPS) to 1440p (46 FPS) loses 25 FPS, and then to 4K (25 FPS) loses another 21 FPS. Medium settings show 84 FPS at 1080p, 54 FPS at 1440p, and 29 FPS at 4K. Ultra preset yields 58 FPS, 37 FPS, and 20 FPS respectively. In every case, the step from 1440p to 4K produces a larger percentage drop than the step from 1080p to 1440p, which is typical of a GPU hitting its memory bandwidth or shading limit as resolution grows.

Notably, the gap between Low and Ultra at each resolution stays relatively consistent — about 38 FPS at 1080p, 25 FPS at 1440p, and 14 FPS at 4K. This narrowing spread at higher resolutions further confirms that the GPU's raw pixel-pushing capability, not the settings overhead, is what caps performance. The CPU, with its 16 MB of L3 cache and 51.2 GB/s dual-channel DDR4 memory bandwidth, is not the constraint here; if it were, we would see smaller FPS differences between resolutions at the same settings.

Settings Recommendations

Given the measured data, the optimal preset depends heavily on the target resolution, but the overall picture favors Low or Medium settings for playable frame rates at 1080p and 1440p. At 1920x1080, Low delivers 96 FPS average, which is the highest measured result in the entire dataset. Medium achieves 84 FPS, still comfortably above 60 FPS, while High drops to 71 FPS and Ultra falls to 58 FPS. For competitive or fast-paced play, Low at 1080p offers the smoothest experience with a 12 FPS advantage over Medium and a 38 FPS advantage over Ultra.

At 2560x1440, Low produces 62 FPS, which is just above the 60 FPS threshold commonly considered acceptable. Medium hits 54 FPS, High manages 46 FPS, and Ultra drops to 37 FPS. The data suggests that 1440p Low is the only preset at this resolution that maintains a playable average, though Medium is close. Users willing to accept sub-60 FPS averages might choose Medium for better visual quality, but the 8 FPS difference between Low and Medium is modest compared to the 17 FPS gap between Low and Ultra.

At 3840x2160, no preset achieves even 40 FPS. Low tops out at 34 FPS, Medium at 29 FPS, High at 25 FPS, and Ultra at 20 FPS. These numbers are all below the minimum for smooth gameplay, so 4K is not a viable option for this combo in Doom. The best experience at 4K would still be Low settings, as it provides the least bad performance, but the data clearly indicates that 1080p is the intended operating resolution for this pairing. For the majority of users, 1080p Medium offers the best balance of visual fidelity and frame rate, sitting 12 FPS above High and only 12 FPS below Low.

GPU Role

The Intel Arc B370 is the primary driver of the performance ceiling observed in this dataset. Its specifications paint a picture of an integrated graphics solution: 1280 shading units, 40 texture mapping units, 20 render output units, and 10 ray tracing cores. The GPU operates at a base clock of 300 MHz and boosts to 2400 MHz, with a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. The FP32 throughput is 6.144 TFLOPS, and FP16 reaches 12.29 TFLOPS with a 2:1 ratio. These are modest figures for modern gaming, and the benchmark results reflect that with a 3DMark Steel Nomad DX12 score of 1184, placing it in the 5th percentile of all GPUs.

The memory configuration is particularly telling: the Arc B370 uses "System Shared" memory, meaning it relies on the CPU's DDR4 pool rather than dedicated VRAM. The memory bandwidth is listed as "System Dependent," which in this case ties to the Ryzen 7 5700G's dual-channel 51.2 GB/s capability. This shared memory architecture is a significant handicap in Doom, a fast-paced FPS that benefits from high memory throughput. The nearest rivals in the GPU benchmark rankings — the ATI Mobility Radeon HD 5570 (1186 score, -0.2% delta), ATI Radeon HD 5770 (1190, -0.5%), AMD Radeon HD 7650M (1192, -0.7%), and AMD FirePro M2000 (1168, +1.4%) — are all older, lower-end parts, confirming that the Arc B370 sits at the entry level of GPU performance.

The GPU's 25 W TDP and IGP slot width further emphasize its integrated nature, and the absence of a dedicated power connector means it draws from the system's existing power delivery. In the context of Doom's measured FPS, the GPU's role is unambiguous: it is the component that determines whether the game is playable. The CPU's benchmarks — such as a Cinebench R23 multicore score of 12830.5 and a Geekbench multicore score of 9950 — are far above what Doom's engine requires, so the GPU's 5th percentile standing is what pushes this combo to the 2696th rank out of 2930.

How This Combo Ranks

The combo's overall standing in Doom is poor, ranking 2696th out of 2930 tested configurations, placing it in the bottom 8% of all systems. This low rank is driven almost entirely by the GPU's performance ceiling, as the CPU is a solid mid-range part. The AMD Ryzen 7 5700G, with its 8 cores and 16 threads based on Zen 3 architecture, achieves a 79th percentile ranking among all CPUs. Its average benchmark score of 27051 sits nearly equidistant between its nearest rivals: the Intel Core i9-9900K (27097, -0.2% delta), Intel Core i5-14400T (27166, -0.4%), AMD Ryzen AI 7 445 (26936, +0.4%), and Intel Core i7-1370P (26900, +0.6%). This means the CPU is essentially on par with a flagship 9th-gen Intel part from 2018, which is respectable for an APU.

However, the GPU's 5th percentile ranking drags the entire combo down. The Arc B370's nearest rivals are all discrete or integrated parts from over a decade ago, underscoring how far behind modern gaming GPUs it sits. In Doom specifically, the measured FPS data shows that even at the lowest resolution and settings, the system only manages 96 FPS, which is far below what a dedicated gaming GPU would achieve. The rank of 2696 out of 2930 suggests that roughly 92% of tested combos deliver better performance in this title.

The contrast between CPU and GPU percentile rankings — 79th versus 5th — creates a massive imbalance. The Ryzen 7 5700G's 16 MB L3 cache and 51.2 GB/s memory bandwidth are more than sufficient for Doom's engine, but the Arc B370's shared memory and modest shading resources become the bottleneck at every resolution tested. This is a textbook case of a CPU outclassing its GPU partner, and the combo rank reflects that mismatch rather than any deficiency in the processor.
