Doom

# How This Combo Ranks

The AMD Ryzen 5 5600G paired with the Intel Arc B370 ranks 2696 out of 2930 tested combinations for Doom. This places the combo in the bottom 8% of all tested systems, which is a low position for a game that is generally well-optimized and runs on a wide range of hardware. The ranking reflects a significant bottleneck: the Arc B370, as an integrated GPU solution, sits at the 5th percentile among all GPUs, while the Ryzen 5 5600G performs much more respectably at the 74th percentile among all CPUs.

The stark mismatch between the CPU's relative strength and the GPU's very low standing is the defining characteristic of this pairing. The data suggests that the integrated graphics solution is the primary constraint, and the CPU is largely underutilized in this title. The combo's rank of 2696 indicates that the vast majority of other tested systems deliver higher average frame rates. The gap between this combo and the top of the rankings is substantial, and the measured FPS data confirms that the system is only capable of producing playable frame rates at lower resolutions and settings. The overall ranking is a direct consequence of the GPU's performance ceiling, which is the lowest component in the chain.

GPU Role

The Intel Arc B370 is an integrated graphics processor (IGP) built on Intel's Xe3-LPG architecture with a 3 nm process. It features 1280 shading units, 40 texture mapping units, and 20 raster output units. The GPU operates at a base clock of 300 MHz and can boost up to 2400 MHz, with a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. Its FP32 performance is rated at 6.144 TFLOPS, and it supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

This GPU is positioned at the 5th percentile among all GPUs, with its only benchmark score being 1184 in 3DMark Steel Nomad DX12. The nearest rivals are the ATI Mobility Radeon HD 5570 (score 1186, delta -0.2%), ATI Radeon HD 5770 (score 1190, delta -0.5%), AMD Radeon HD 7650M (score 1192, delta -0.7%), and AMD FirePro M2000 (score 1168, delta 1.4%). The Arc B370's performance is essentially on par with these older discrete and mobile graphics solutions, which explains its low percentile ranking.

The GPU's memory is system shared, with a system-dependent bandwidth and a 25 W TDP. This is a critical limitation for Doom, a fast-paced FPS that benefits from dedicated VRAM. The measured FPS data shows that at 4K Ultra, the combo manages only 20 FPS, while at 1080p Low it reaches 96 FPS. The memory subsystem being shared with the CPU means that there is no dedicated VRAM bandwidth, which likely contributes to the GPU's inability to maintain higher frame rates at higher resolutions and settings. The combination of low shading unit count, shared memory, and the fact that this is an integrated part of a mobile-focused architecture (Arc Graphics-M, Panther Lake) makes it fundamentally unsuited for demanding titles at high resolutions.

CPU Role

The AMD Ryzen 5 5600G is a desktop processor from the 5000 series, built on the Zen 3 architecture (Cezanne) using a 7 nm TSMC process. It has 6 cores and 12 threads, with a base clock of 3.90 GHz and a boost clock of 4.40 GHz. The CPU features 64 KB L1 cache per core, 512 KB L2 cache per core, and 16 MB of L3 cache. It supports dual-channel DDR4 memory with a bandwidth of 51.2 GB/s and uses the AMD Socket AM4 interface with PCIe Gen 3 (16 lanes). The TDP is 65 W, and it includes integrated Radeon Vega 7 graphics.

The 5600G performs well in synthetic benchmarks. Its Cinebench R23 multicore score is 10551, and its single-core score is 1409. In Geekbench, it scores 8428 multicore and 1801 single-core. The Passmark multithread score is 19717, and the single-thread score is 3177. The data shows the CPU sits at the 74th percentile among all CPUs, with an average benchmark score of 21088. Its nearest rivals are the Intel Core i3-1220P (score 21066, delta 0.1%), Intel Core Ultra 7 256V (score 21112, delta -0.1%), AMD Ryzen 5 7530U (score 21133, delta -0.2%), and Intel Core Ultra 7 155U (score 21174, delta -0.4%). The 5600G is essentially performance-equivalent to these competitors, with deltas of just a fraction of a percent.

For Doom, the CPU's role is to feed the GPU with draw calls and handle game logic. With 6 cores and 12 threads, the 5600G is more than capable of running this title at high frame rates. The measured FPS data shows that the combo hits 96 FPS at 1080p Low, which is likely near the CPU's ability to push frames in this scenario. However, the GPU becomes the bottleneck at higher settings and resolutions, as evidenced by the FPS dropping to 71 at 1080p High and 46 at 1440p High. The CPU's strong single-thread performance, as indicated by its 1409 Cinebench R23 single-core score, is sufficient for Doom's engine, but the GPU's limitations prevent the system from fully utilizing the CPU's capabilities.

Measured FPS Breakdown

The measured FPS data provides a clear picture of the combo's performance across resolutions and settings. At 1920x1080, the combo delivers 96 FPS on Low settings, 84 FPS on Medium (with min 71 and max 96), 71 FPS on High, and 58 FPS on Ultra. The 1080p Low result is the only one that approaches the 100 FPS mark, and the drop from Low to Ultra is 38 FPS, representing a 40% reduction.

Moving to 2560x1440, the performance drops significantly. Low settings yield 62 FPS, Medium gives 54 FPS (min 46, max 62), High provides 46 FPS, and Ultra falls to 37 FPS. The delta between Low and Ultra at 1440p is 25 FPS, which is a 40% reduction as well, but the absolute numbers are much lower. At 3840x2160, the combo struggles. Low settings produce 34 FPS, Medium gives 29 FPS (min 25, max 34), High yields 25 FPS, and Ultra drops to 20 FPS.

The data indicates that the combo can achieve playable frame rates (above 60 FPS) only at 1080p Low and Medium settings. At 1440p, only Low settings reach 62 FPS, which is barely above the 60 FPS threshold. At 4K, all settings result in sub-60 FPS performance, with Ultra being nearly unplayable at 20 FPS. The min and max FPS data for Medium settings shows variation: at 1080p, the range is 71-96 FPS; at 1440p, it is 46-62 FPS; and at 4K, it is 25-34 FPS. This variation suggests frame pacing issues, likely due to the shared memory bottleneck and the GPU's limited compute resources.

A: At 1920x1080, the combo achieves 96 FPS on Low and 58 FPS on Ultra. This is a 38 FPS difference, or a 40% reduction in average frame rate when moving from the lowest to the highest preset.

Q: Does the combo maintain consistent frame rates at Medium settings?

A: The data shows variation. At 1080p Medium, the range is 71 to 96 FPS. At 1440p Medium, the range is 46 to 62 FPS. At 4K Medium, the range is 25 to 34 FPS. This indicates inconsistent frame pacing, with the spread being wider at lower resolutions.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target frame rate and resolution. For a smooth 60+ FPS experience, 1920x1080 with Medium settings is the recommended choice. The data shows 84 FPS average at this configuration, with a min of 71 FPS. This provides a comfortable margin above the 60 FPS threshold and maintains a decent visual quality.

If the user prioritizes the highest possible frame rate, 1920x1080 with Low settings delivers 96 FPS. This is the only configuration in the measured data that approaches 100 FPS, and it will provide the most responsive gameplay for a fast-paced FPS like Doom. However, the visual fidelity will be reduced, as Low settings typically disable shadows, reflections, and other effects.

For users with a 1440p monitor, Low settings at 2560x1440 yield 62 FPS, which is just above the 60 FPS mark. This is the only 1440p configuration that is playable, but the margin is thin. Medium settings at 1440p drop to 54 FPS, which may cause noticeable stuttering in intense combat scenes. At 4K, all settings result in sub-35 FPS performance, making the game unplayable at a smooth frame rate. The Ultra preset at any resolution is not recommended, as it consistently produces the lowest FPS: 58 FPS at 1080p, 37 FPS at 1440p, and 20 FPS at 4K.

The data suggests that the best "experience" in terms of balancing visual quality and performance is 1080p Medium. It offers 84 FPS, which is well above the playability threshold, and the Medium preset in Doom retains a reasonable level of graphical fidelity without the heavy performance cost of High or Ultra. For competitive players, 1080p Low is the best choice due to the higher frame rate and reduced input latency. Users should avoid 1440p and 4K entirely unless they are willing to accept sub-60 FPS performance.

Resolution Scaling

The FPS data across resolutions shows a clear and expected trend: performance degrades as resolution increases. At Low settings, the combo delivers 96 FPS at 1080p, 62 FPS at 1440p, and 34 FPS at 4K. This represents a 35% drop from 1080p to 1440p, and a further 45% drop from 1440p to 4K. The total drop from 1080p to 4K at Low settings is 62 FPS, or a 65% reduction.

At Medium settings, the trend is similar but with lower absolute numbers: 84 FPS at 1080p, 54 FPS at 1440p, and 29 FPS at 4K. The drop from 1080p to 1440p is 30 FPS (36%), and from 1440p to 4K is 25 FPS (46%). At High settings, the performance is 71 FPS at 1080p, 46 FPS at 1440p, and 25 FPS at 4K. The drop from 1080p to 1440p is 25 FPS (35%), and from 1440p to 4K is 21 FPS (46%).

The scaling pattern indicates that the GPU is the limiting component. If the CPU were the bottleneck, we would expect the FPS to remain relatively constant as resolution increases, since the CPU's workload is primarily resolution-independent. Instead, the FPS drops significantly at each step, which is characteristic of a GPU-bound scenario. The Arc B370's shared memory architecture and low pixel rate (48.00 GPixel/s) mean that it cannot keep up with the increasing pixel count at higher resolutions.

The data also shows that the percentage drop from 1080p to 1440p is consistently around 35%, and from 1440p to 4K is around 45-46%, regardless of the settings preset. This consistency suggests that the GPU's performance scales linearly with the number of pixels, which is expected for a fill-rate-limited GPU. The 4K resolution has 4 times the pixels of 1080p, and the FPS at 4K Low (34) is roughly one-third of the FPS at 1080p Low (96), indicating a near-linear scaling that confirms the GPU is fully saturated at all resolutions. The CPU, with its 6 cores and 12 threads, is not the constraint here; rather, the Arc B370's limited pixel throughput and shared memory bandwidth cap the system's performance.
