Doom

The AMD Ryzen 5 7400F paired with the Intel Arc B370 delivers a playable but constrained experience in Doom, with the GPU acting as the primary bottleneck at every resolution. The measured frame rates show a system that can handle 1080p gaming comfortably, but struggles to maintain smooth performance at 4K. This combination ranks 2696 out of 2930 tested combos for this title, placing it in the lower percentile of possible configurations.

Resolution Scaling

The data reveals a steep performance drop as resolution increases, which clearly points to the Intel Arc B370 as the limiting factor. At 1080p with High settings, the combo averages 71 FPS. Moving to 1440p drops that to 46 FPS, a reduction of 25 frames. At 4K, the average falls to 25 FPS, which is a 46-frame decline from 1080p. This scaling pattern is characteristic of a GPU-bound scenario, where the rendering load increases with pixel count and the Arc B370’s compute resources become saturated.

Looking at the Low preset, the same trend emerges. At 1080p, the average is 96 FPS. At 1440p, it drops to 62 FPS, and at 4K it reaches 34 FPS. The percentage drop from 1080p to 4K on Low is substantial, showing that even with reduced graphical fidelity, the GPU cannot maintain high frame rates at higher resolutions. The Arc B370’s 3DMark Steel Nomad DX12 score of 1184 places it in the 5th percentile of all GPUs, and its nearest rivals include the ATI Mobility Radeon HD 5570 and ATI Radeon HD 5770, which are older parts. This low absolute performance explains why 4K is not viable.

The difference between 1080p and 1440p is also notable. On High settings, the drop from 71 to 46 FPS represents a 35% reduction. On Low settings, the drop from 96 to 62 FPS is a 35% reduction as well. This consistent scaling suggests that the GPU’s fill rate and shading capacity are being taxed proportionally with resolution. The Arc B370 has a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s, which are modest figures for 4K rendering.

At 4K, the differences between presets are compressed. Ultra averages 20 FPS, High 25 FPS, Medium 29 FPS, and Low 34 FPS. The spread between Low and Ultra is only 14 FPS. This narrow margin indicates that the GPU is already at its limit, and further reducing settings yields diminishing returns. The limiting component is clearly the GPU, as the Ryzen 5 7400F has ample processing power for this title. The CPU’s Cinebench R23 multicore score of 21765 and single-core score of 3072 show it is far more capable than what this game requires.

Settings Recommendations

For this configuration, the best experience depends on the target resolution. At 1080p, Medium settings provide a strong balance, with an average of 84 FPS and a minimum of 71 FPS. This keeps frame rates above 60 FPS consistently, which is important for a fast-paced FPS like Doom. High settings at 1080p average 71 FPS, which is also playable, but the minimum frame rates are not reported, so Medium offers more headroom. Low settings at 1080p reach 96 FPS, but the visual quality reduction may not be worth the extra frames.

At 1440p, Low settings are the only option that maintains a comfortable average, hitting 62 FPS. Medium at 1440p averages 54 FPS with a minimum of 46 FPS, which means dips below 60 FPS are possible. High at 1440p averages 46 FPS, and Ultra drops to 37 FPS. For a smooth experience at 1440p, Low is the recommended preset. The jump from Low to Medium at 1440p is only 8 FPS, while the visual uplift may be modest, so users must decide if the frame rate trade-off is acceptable.

At 4K, no preset delivers a consistently playable experience. The highest average is 34 FPS on Low, which is below the 60 FPS threshold for smooth gameplay. Medium at 4K averages 29 FPS, High 25 FPS, and Ultra 20 FPS. Given these numbers, 4K is not a recommended target for this combo. The data suggests that 1080p Medium is the sweet spot, offering 84 FPS average with a minimum of 71 FPS. This provides enough performance for the game’s fast action while retaining a reasonable level of visual detail.

Comparing settings at 1080p, the progression from Low to Medium to High to Ultra yields averages of 96, 84, 71, and 58 FPS respectively. The step from Low to Medium is 12 FPS, from Medium to High is 13 FPS, and from High to Ultra is 13 FPS. Each step costs roughly the same amount of performance, so there is no single preset that offers a disproportionate benefit. The choice between Medium and High comes down to whether the user prioritizes frame rate or visual fidelity, but Medium has the advantage of a reported minimum of 71 FPS, ensuring no severe drops.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. With Low settings, the average frame rate is 96 FPS. Medium settings bring the average down to 84 FPS, with a minimum of 71 FPS and a maximum of 96 FPS. High settings average 71 FPS, and Ultra settings average 58 FPS. The progression shows that even at the highest preset, the system stays above 55 FPS, which is acceptable for casual play but may not be ideal for competitive scenarios.

Moving to 2560x1440, the performance drops significantly. Low settings average 62 FPS, which is the only preset at this resolution to exceed 60 FPS. Medium settings average 54 FPS, with a minimum of 46 FPS and a maximum of 62 FPS. High settings average 46 FPS, and Ultra settings average 37 FPS. The gap between Low and Ultra is 25 FPS, indicating that the GPU’s limited resources are heavily taxed by higher graphical fidelity.

At 3840x2160, the results are sub-60 FPS across the board. Low settings average 34 FPS, Medium settings average 29 FPS with a minimum of 25 FPS and a maximum of 34 FPS, High settings average 25 FPS, and Ultra settings average 20 FPS. The differences between presets are smaller here, with only a 14 FPS spread between Low and Ultra. This compression suggests the GPU is hitting a hard performance ceiling regardless of settings.

The minimum and maximum values are only reported for the Medium preset at each resolution. At 1080p Medium, the range is 71 to 96 FPS, showing a 25 FPS variance. At 1440p Medium, the range is 46 to 62 FPS, a 16 FPS variance. At 4K Medium, the range is 25 to 34 FPS, a 9 FPS variance. This tightening of the frame time variance at higher resolutions further confirms the GPU is the limiting factor, as it cannot push beyond its raw capabilities.

GPU Role

The Intel Arc B370 is the decisive component in this pairing. Its 3DMark Steel Nomad DX12 score of 1184 places it at the 5th percentile of all GPUs, with nearest rivals being the ATI Mobility Radeon HD 5570 (1186), ATI Radeon HD 5770 (1190), AMD Radeon HD 7650M (1192), and AMD FirePro M2000 (1168). These are all older, lower-performance parts, which contextualizes the Arc B370’s position in the market.

The GPU’s clocks are modest, with a base clock of 300 MHz and a boost clock of 2400 MHz. The memory is system shared, meaning it has no dedicated VRAM, and the bandwidth is system dependent. This shared memory architecture can limit performance in memory-intensive scenarios, though Doom is not particularly demanding in that regard. The shader count is 1280, with 40 TMUs and 20 ROPs. The pixel rate is 48.00 GPixel/s, and the texture rate is 96.00 GTexel/s.

The FP32 performance is 6.144 TFLOPS, which is a low figure for modern GPUs. This explains why 4K rendering is not feasible, as the pixel throughput required at 3840x2160 exceeds what the GPU can deliver. The GPU’s 25 W TDP and integrated form factor (IGP) suggest it is designed for efficiency rather than raw performance, which aligns with its 5th percentile ranking.

In Doom specifically, the GPU’s performance ceiling is evident in the 4K results. Even at Low settings, the average is only 34 FPS, which is below the standard for smooth gameplay. The GPU’s nearest rivals all score close to 1184, and the deltaPct values are minimal (ranging from -0.7 to 1.4), indicating that the Arc B370 is not meaningfully faster or slower than its closest competitors. This places it in a performance tier that is simply not suited for high-resolution gaming.

CPU Role

The AMD Ryzen 5 7400F provides a strong foundation for this combo, with specifications that far exceed what Doom requires. It has 6 cores and 12 threads, with a base clock of 3.70 GHz and a boost clock of 4.70 GHz. The 7000 series chip uses the Zen 4 architecture, built on a 5 nm process at TSMC. Its cache configuration includes 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache.

Benchmark results show the CPU is highly capable. In Cinebench R23, it scores 21765 in multicore and 3072 in single-core. In Cinebench R20, it scores 9141 multicore and 1290 single-core. PassMark results include a multithread score of 25645 and a single-thread score of 3689. The CPU’s average benchmark score is 32750, placing it in the 83rd percentile of all CPUs. Its nearest rivals are the Intel Core i5-14600T (32707, 0.1% delta), Intel Core Ultra 7 155H (32697, 0.2% delta), AMD Ryzen 7 PRO 6850H (32812, -0.2% delta), and AMD Ryzen AI 7 PRO 360 (32662, 0.3% delta). These scores are all within a fraction of a percent, showing that the 7400F is competitively positioned.

In Doom, the CPU’s role is supportive. The frame rates scale with resolution in a way that indicates the GPU is the bottleneck, not the CPU. If the CPU were limiting, we would expect similar frame rates across resolutions, but the data shows a clear decline from 1080p to 4K. The CPU’s single-thread performance, as evidenced by the Cinebench R23 single-core score of 3072, is more than sufficient for Doom’s engine, which typically relies on a few fast cores.

The CPU’s memory support includes DDR5 with a dual-channel bus and a bandwidth of 83.2 GB/s. This memory bandwidth is more than adequate for the game’s data transfer needs. The CPU also supports PCIe Gen 5 with 24 lanes, though the Arc B370’s IGP bus interface means it does not use a discrete PCIe connection. The CPU’s 65 W TDP and 6,570 million transistors on a 71 mm² die indicate a power-efficient design that does not generate excessive heat, allowing the GPU to operate without thermal constraints.

The combination of a high-percentile CPU with a low-percentile GPU creates a lopsided system where the CPU sits idle waiting for the GPU to render frames. This is confirmed by the combo rank of 2696 out of 2930, which places it in the bottom 8% of configurations. The CPU is not the issue; the Arc B370 simply cannot keep up with the 7400F’s processing power in this title. For users with this combo, the path to better performance lies in reducing resolution or settings, not in upgrading the CPU.
