Doom

The Intel Core i5-12400F paired with the Intel Arc B370 presents a specific performance profile in Doom, characterized by a stark dependency on resolution and settings. The measured data indicates that this combination is best suited for 1080p gaming, where it achieves playable frame rates, but it struggles significantly at higher resolutions. The following analysis breaks down the benchmark results, focusing on the optimal settings, the GPU's role, and how this combo ranks against others.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this combo is achieved at 1080p with Low settings. This configuration delivers an average of 96 FPS, which is the highest frame rate recorded for any resolution or settings combination in the dataset. This provides a significant performance buffer and ensures smooth gameplay, especially for a fast-paced FPS title. While the Medium preset at 1080p also offers a solid 84 FPS average, the jump to High settings results in a noticeable drop to 71 FPS. The Ultra preset at 1080p is the least favorable option at this resolution, yielding only 58 FPS, which, while playable, sacrifices the fluidity that makes Doom engaging.

At 1440p, the data shows that the combo becomes more constrained. The Low preset is the only viable option for a consistently smooth experience, producing an average of 62 FPS. The Medium preset at this resolution drops to 54 FPS, and High falls to 46 FPS. The Ultra preset at 1440p is not recommended, as it averages only 37 FPS, which is below the threshold for comfortable play in a demanding action game.

The 4K results are largely impractical for this hardware combination. Even the Low preset only manages an average of 34 FPS, and the High preset drops to 25 FPS. The Ultra preset at 4K is the worst-case scenario, with an average of just 20 FPS. Therefore, the data strongly indicates that users should prioritize 1080p with Low or Medium settings to get the best balance of performance and visual quality from this specific CPU-GPU pairing. The performance scaling from Low to High settings is steep, suggesting that the GPU is a limiting factor at higher quality presets.

GPU Role

The Intel Arc B370 is an integrated graphics processor (IGP) with a 25 W TDP, and its role in this combo is the primary determinant of gaming performance. The GPU's memory is "System Shared," meaning it relies on the system's main memory rather than dedicated VRAM. Consequently, its memory bandwidth is "System Dependent," which creates a significant bottleneck in demanding scenarios. The GPU's boost clock is rated at 2400 MHz, and its base clock is 300 MHz, but its performance is heavily influenced by the shared memory subsystem.

The benchmark data for the GPU shows a single 3DMark Steel Nomad DX12 score of 1184, placing it in the 5th percentile of all GPUs. Its nearest rivals in the database include the ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, and AMD Radeon HD 7650M, with score deltas of -0.2%, -0.5%, and -0.7% respectively. This indicates that the Arc B370's raw compute performance is in the same class as these older, entry-level discrete parts, which is a telling sign of its limited capabilities for high-end gaming.

In the context of Doom, the GPU's limitations are evident in the frame rate scaling. At 1080p, the difference between the Low and Ultra presets is 38 FPS (96 vs 58), a 65% drop in performance when the graphical load is increased. This suggests that while the CPU (Intel Core i5-12400F) has enough headroom to feed the GPU at lower settings, the Arc B370 becomes saturated quickly as the visual fidelity increases. The GPU's 1280 shading units and 20 ROPs are simply not sufficient to handle the increased pixel shading and texture work at higher presets, making it the clear bottleneck in this system for this game.

FAQ

Q: What is the highest average frame rate this combo can achieve in Doom?

A: The highest recorded average frame rate is 96 FPS, which is achieved at 1920x1080 resolution with the Low settings preset.

Q: Is this combo capable of playing Doom at 4K resolution?

A: The benchmark data indicates that 4K is not a viable option. The best average FPS at 3840x2160 is 34 FPS on the Low preset, which is below the standard for smooth, playable performance.

Q: How does the combo perform at 1440p compared to 1080p?

A: At 2560x1440, the performance drops significantly. For example, on the High preset, the average frame rate falls from 71 FPS at 1080p to 46 FPS at 1440p, a reduction of 25 FPS.

Q: Which component is the primary bottleneck in this system?

A: The data points to the Intel Arc B370 GPU as the primary bottleneck. The frame rate drops sharply when increasing graphical settings or resolution, indicating the GPU's performance limits are reached quickly, while the CPU has sufficient capacity to handle the workload.

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

A: At 1920x1080, the Low preset averages 96 FPS, while the Ultra preset averages 58 FPS. This represents a performance decrease of 38 FPS when moving from the lowest to the highest quality settings.

Q: How does the Intel Arc B370's benchmark score compare to its nearest rivals?

A: The GPU's 3DMark Steel Nomad score is 1184. This is nearly identical to the ATI Mobility Radeon HD 5570 (1186), ATI Radeon HD 5770 (1190), and AMD Radeon HD 7650M (1192), placing it in the same performance tier as these older GPUs.

How This Combo Ranks

The Intel Core i5-12400F and Intel Arc B370 combination is ranked 3425 out of 3712 tested combos for Doom. This places it in the bottom 8% of all systems tested, underscoring its status as a low-performance configuration. The rank is a direct reflection of the GPU's limitations, as the CPU is a relatively capable mid-range part. The i5-12400F itself has a percentile of 73 against all CPUs, indicating it performs better than most processors in general benchmarks. However, the GPU's 5th percentile ranking drags the entire combo down.

The combination's poor ranking is further emphasized by the GPU's nearest rivals, which are all older, low-end parts from a different era. This suggests that in a modern game like Doom, the Arc B370 is not competitive with most dedicated graphics solutions, even those from several generations ago. The high combo rank number signifies that the vast majority of other CPU-GPU pairings in the database will deliver superior frame rates. For context, if the i5-12400F were paired with a more powerful discrete GPU, the combo's ranking would likely be much higher, but the Arc B370's integrated nature severely limits the overall gaming potential of this system.

Resolution Scaling

The performance scaling from 1080p to 4K clearly illustrates the GPU's dominance as the limiting factor. At 1080p with Low settings, the combo achieves 96 FPS. Moving to 1440p on the same settings drops the average to 62 FPS, a 35% reduction. At 4K, the frame rate plummets to 34 FPS, which is a 65% decrease from the 1080p result. This pattern is consistent across all settings presets.

For example, on High settings, the average frame rate goes from 71 FPS at 1080p, to 46 FPS at 1440p, and finally to 25 FPS at 4K. The drop from 1440p to 4K is particularly severe, with the frame rate nearly halving. This behavior indicates that the GPU is being overwhelmed as the pixel count increases. A system with a more powerful GPU would typically show a smaller percentage drop in frame rates when scaling resolution, as the CPU would start to become the bottleneck at 1080p. Here, the consistent and significant drop at each resolution step confirms that the Arc B370's pixel throughput and memory bandwidth are insufficient for higher resolutions, making 1080p the only practical target for this hardware.

The data shows a clear hierarchy. The 1080p Low preset is the only configuration that breaks the 60 FPS barrier with significant headroom. The 1080p Medium and High presets are also playable, but the Ultra preset dips below 60 FPS. At 1440p, only the Low preset achieves an average above 60 FPS. All 4K presets fail to reach 35 FPS, making them unsuitable for gameplay. The minimum and maximum FPS data points for the Medium presets at each resolution show a consistent spread, with the minimum frame rate matching the average of the High preset at the same resolution, indicating that performance can fluctuate significantly during intense scenes.
