CPU Role

The AMD Ryzen 7 7800X3D is a high-end desktop processor with 8 cores and 16 threads, based on the Zen 4 architecture on a 5 nm process. It operates with a base clock of 4.20 GHz and a boost clock of 5.00 GHz, with a TDP of 120 W. Its cache configuration is substantial, featuring 64 KB of L1 cache per core, 1 MB of L2 cache per core, and a large 96 MB of shared L3 cache, which is a defining characteristic of the X3D series.

Benchmark results indicate this CPU is well-suited for gaming workloads. Its Cinebench R23 multicore score is 16817, and its single-core score is 1713. In Geekbench, it achieves 15610 multicore and 2426 single-core. The 3DMark results show a strong scaling from 1887 in the 2-thread test to 7980 in the 16-thread test, indicating good multi-threading capability. The Passmark multithread score of 34293 and single-thread score of 3759 further confirm its strong overall performance.

In the context of this game combo, the CPU’s role is to feed frames to the GPU. Its 83rd percentile ranking among all CPUs suggests it is more than capable of handling the processing demands of Doom. The data shows that the CPU is not the bottleneck here; even at lower resolutions where CPU load typically increases, the frame rates are limited by the graphics solution. The CPU's performance headroom is evidenced by the fact that the frame rates scale almost linearly with resolution changes, a hallmark of a GPU-limited scenario.

GPU Role

The Intel Arc B370 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, manufactured on a 3 nm process by Intel. It has a base clock of 300 MHz and a boost clock of 2400 MHz. Its memory configuration is "System Shared," meaning it relies on the system’s main memory for VRAM, with bandwidth described as "System Dependent." The GPU features 1280 shading units, 40 texture mapping units, and 20 raster output units, along with 10 ray tracing cores. Its theoretical performance is rated at 6.144 TFLOPS for FP32 and 12.29 TFLOPS for FP16.

The GPU’s benchmark standing is extremely low, with a percentile rank of 5 among all GPUs. Its average benchmark score is 1184, based on a single 3DMark Steel Nomad DX12 test. Its nearest rivals, such as the ATI Mobility Radeon HD 5570 and ATI Radeon HD 5770, have nearly identical average scores, with delta percentages of -0.2% and -0.5% respectively. This places the Arc B370 in the same performance tier as graphics hardware from over a decade ago.

In Doom, the GPU’s limitations are immediately apparent. At 1080p with Low settings, it manages an average of 96 FPS, but this drops to 58 FPS at Ultra settings. At 1440p, the average FPS ranges from 62 (Low) to 37 (Ultra). At 4K, the highest average is 34 FPS on Low, falling to 20 FPS on Ultra. These numbers clearly indicate that the Arc B370 is the primary constraint on performance, struggling to maintain high frame rates at higher resolutions and quality presets.

How This Combo Ranks

The combination of the Ryzen 7 7800X3D and Intel Arc B370 ranks 2696th out of 2930 tested combos in Doom. This places it in the bottom 8% of all configurations, a position that reflects the severe imbalance between the high-performing CPU and the low-performing GPU.

This ranking is directly attributable to the GPU’s poor benchmark performance. While the CPU ranks in the 83rd percentile, the GPU ranks in the 5th percentile. The disparity is stark. The data indicates that the overall combo ranking is dragged down by the graphics card, which is a classic case of a bottleneck. The CPU has significant untapped potential, but it cannot be realized because the GPU is unable to process frames fast enough.

The rank of 2696 out of 2930 underscores that this is not a configuration for high-end gaming. It is a pairing that will struggle with modern titles at high settings. The frame rates measured in Doom, which is a well-optimized game from 2016, confirm this. The combo’s performance is more in line with entry-level or older hardware, making it suitable for esports titles or older games at lower resolutions, but not for demanding AAA experiences.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the user’s preference for frame rate versus visual quality. There is no single "best" setting, as the trade-offs are clear across the resolution and preset spectrum.

For a smooth and responsive experience, the Low preset at 1920x1080 is the recommended choice. It delivers an average FPS of 96, which is well above the 60 FPS threshold for smooth gameplay. This setting provides the highest performance headroom and is the only configuration that approaches 100 FPS. The Medium preset at 1080p offers 84 FPS, which is also playable, and provides a moderate increase in visual fidelity over Low.

At 2560x1440, the Low preset yields 62 FPS, which is acceptable, but the Medium preset drops to 54 FPS. For users with a 1440p monitor who prioritize a stable frame rate, Low is the safer choice. The High and Ultra presets at 1440p, with average FPS of 46 and 37 respectively, are not recommended for fast-paced gameplay.

At 3840x2160, none of the presets provide a playable experience. The highest average is 34 FPS on Low, which is below the 30 FPS minimum for most players and far from the 60 FPS ideal. Therefore, 4K gaming should be avoided entirely with this combo. The data suggests that the best experience is achieved at 1080p with Low or Medium settings, balancing frame rate and visual quality.

Measured FPS Breakdown

The measured FPS data provides a detailed look at the combo’s performance across three resolutions and four quality presets.

At 1920x1080, the average frame rates are as follows:

• Low: 96 FPS
• Medium: 84 FPS (min 71, max 96)
• High: 71 FPS
• Ultra: 58 FPS

At 2560x1440, the average frame rates are:

• Low: 62 FPS
• Medium: 54 FPS (min 46, max 62)
• High: 46 FPS
• Ultra: 37 FPS

At 3840x2160, the average frame rates are:

• Low: 34 FPS
• Medium: 29 FPS (min 25, max 34)
• High: 25 FPS
• Ultra: 20 FPS

The data shows a consistent pattern: for each resolution, the Low preset offers the highest average FPS, followed by Medium, then High, with Ultra being the lowest. The delta between Low and Ultra is substantial. At 1080p, the difference is 38 FPS (96 vs 58). At 1440p, it is 25 FPS (62 vs 37). At 4K, it is 14 FPS (34 vs 20).

The minimum and maximum FPS values recorded for the Medium preset at each resolution show a wide variance. At 1080p, the range is 71 to 96 FPS, a spread of 25 FPS. At 1440p, the range is 46 to 62 FPS, a spread of 16 FPS. At 4K, the range is 25 to 34 FPS, a spread of 9 FPS. This variance suggests that the GPU’s performance can fluctuate significantly during gameplay, which could lead to noticeable stuttering in more demanding scenes.

Resolution Scaling

The frame rate drop from 1080p to 4K is significant and reveals the nature of the performance bottleneck. At the Low preset, the average FPS drops from 96 at 1920x1080 to 62 at 2560x1440, and then to 34 at 3840x2160. This represents a 35% reduction from 1080p to 1440p, and a further 45% reduction from 1440p to 4K. Overall, the move from 1080p to 4K results in a 65% decrease in average FPS.

The scaling pattern is consistent across all presets. At Medium, the FPS drops from 84 to 54 to 29. At High, it drops from 71 to 46 to 25. At Ultra, it drops from 58 to 37 to 20. The consistent percentage drops across presets indicate that the GPU is the limiting factor at all quality settings.

The steep decline in FPS as resolution increases is a classic sign of a GPU-bound system. When the resolution increases, the number of pixels that need to be rendered grows exponentially, placing a heavier load on the GPU’s shading units and ROPs. The Arc B370, with its 20 ROPs and 6.144 TFLOPS of FP32 performance, is simply not powerful enough to handle the increased pixel throughput at higher resolutions.

This scaling behavior has practical implications. The combo is only viable for 1080p gaming, where it can achieve playable frame rates on Low and Medium settings. At 1440p, performance is marginal, and at 4K, it is unplayable. The data shows that the CPU has ample headroom to handle the game logic and draw calls at any resolution, but the GPU’s rendering capabilities cap the final output. The limiting component is unambiguously the Intel Arc B370.
