Doom

The Intel Core i5-13400F paired with the Intel Arc B370 ranks 2696th out of 2930 tested combos in Doom, placing it in the bottom 8% of all configurations. This is a fundamentally constrained pairing, and the benchmark data reflects a system that struggles to maintain playable frame rates at higher resolutions. The combination of a mid-range 13th Gen CPU with a low-tier integrated graphics solution from the Arc Graphics-M series creates a bottleneck that is almost entirely GPU-bound, as the data will show across all measured settings.

How This Combo Ranks

The combo's rank of 2696 out of 2930 tested combinations places it in the 8th percentile of all tested systems for this title. This is a low ranking, indicating that the vast majority of other CPU-GPU pairings deliver better performance in Doom. The data suggests this configuration is best suited for 1080p gaming at lower settings, as the performance ceiling is quite low. The ranking is not surprising given that the Intel Arc B370 sits at the 5th percentile among all GPUs, while the Core i5-13400F is at the 77th percentile among all CPUs. This massive disparity between the CPU's relative strength and the GPU's relative weakness defines the entire performance profile of this combo. The measured frames per second at 1080p Low (96 FPS) represent the absolute peak of what this system can deliver, and that score is achieved only by minimizing the graphical load on the GPU. At higher resolutions and settings, the system falls below the 60 FPS threshold that is often considered the baseline for smooth first-person shooter gameplay.

FAQ

GPU Role

The Intel Arc B370 is the decisive component in this system's performance. Its specifications paint a clear picture of a low-power, integrated graphics solution. The GPU operates at a base clock of 300 MHz and a boost clock of 2400 MHz, built on a 3 nm process node. It features 1280 shading units, 40 texture mapping units, and 20 render output units. The memory configuration is listed as "System Shared," meaning it relies on the system's main memory rather than dedicated VRAM, with bandwidth that is "System Dependent." This architecture explains its limited performance.

The GPU's average benchmark score is 1184, placing it in the 5th percentile of all GPUs. Its nearest rivals in terms of raw score are all older, low-end cards: the ATI Mobility Radeon HD 5570 (1186, -0.2% delta), ATI Radeon HD 5770 (1190, -0.5% delta), and AMD Radeon HD 7650M (1192, -0.7% delta). The fact that this modern integrated GPU is trading blows with decade-old discrete cards underscores its low absolute performance level. In Doom, this translates directly to the measured FPS. The GPU's limited pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are insufficient for high-resolution, high-detail rendering. The data shows that at 4K Ultra, the system can only manage 20 FPS, which is a direct consequence of the GPU being overwhelmed by the fill-rate demands of the game.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the system's capabilities across three resolutions and four settings presets. At 1920x1080, the system performs at its best. The Low preset achieves an average of 96 FPS, the Medium preset 84 FPS, the High preset 71 FPS, and the Ultra preset 58 FPS. The Medium preset's data also shows a minimum of 71 FPS and a maximum of 96 FPS, which aligns with the surrounding data points. This resolution is the only one where the system can maintain frame rates above 60 FPS for most settings, with Ultra being the only exception at 58 FPS.

Moving to 2560x1440, performance drops noticeably. The Low preset averages 62 FPS, which is still playable, but the Medium preset drops to 54 FPS, High to 46 FPS, and Ultra to 37 FPS. The data for the Medium preset shows a minimum of 46 FPS and a maximum of 62 FPS. This resolution is borderline for this combo, as only the Low preset manages to stay above the 60 FPS mark. At 3840x2160, the system is clearly out of its depth. The Low preset averages 34 FPS, Medium 29 FPS, High 25 FPS, and Ultra a mere 20 FPS. The Medium preset's data shows a range of 25 to 34 FPS. These frame rates are generally considered unplayable for a fast-paced shooter like Doom, where smooth and responsive controls are critical.

Resolution Scaling

The performance drop from 1080p to 4K is severe and reveals a classic GPU-bound scenario. At 1080p Low, the system achieves 96 FPS. At 1440p Low, it drops to 62 FPS, a 35% reduction. At 4K Low, it falls to 34 FPS, a 65% reduction from the 1080p baseline. This pattern is consistent across all settings. For example, at High settings, the FPS drops from 71 at 1080p to 46 at 1440p and then to 25 at 4K. The scaling is not linear but exponential in its decline, which is typical when the GPU's fill rate and memory bandwidth become the primary bottlenecks.

This steep drop-off indicates that the Intel Core i5-13400F is not the limiting factor. If the CPU were the bottleneck, we would expect to see similar frame rates across different resolutions, as the CPU's workload does not change significantly with resolution. Instead, the FPS scales inversely with the number of pixels rendered, which is the definition of a GPU-limited workload. The CPU's capabilities, such as its 10 cores and 16 threads with a boost clock of 4.60 GHz, are more than sufficient to feed this GPU. The data suggests that the CPU is likely idle or underutilized while the GPU struggles to keep up with the rendering demands of the game at higher resolutions.

Settings Recommendations

Based on the measured FPS rows, the optimal experience for this combo is at 1920x1080 with the Low preset, which yields an average of 96 FPS. This is the only configuration where the system achieves near-100 FPS performance, providing a smooth and responsive experience for a fast-paced shooter. The Medium preset at 1080p also offers a solid experience with an average of 84 FPS, and it provides a better visual quality without sacrificing too much performance. For players who prioritize visual fidelity over raw frame rate, the High preset at 1080p (71 FPS) is still viable, but the Ultra preset at 58 FPS dips below the 60 FPS threshold and may feel less smooth during intense combat sequences.

At 2560x1440, the only recommended setting is Low, which averages 62 FPS. This provides a playable experience, but the visual quality is significantly reduced. The Medium (54 FPS), High (46 FPS), and Ultra (37 FPS) presets at this resolution are all below the 60 FPS target and are not recommended for a game that demands quick reflexes. At 3840x2160, no settings are recommended, as even the Low preset averages only 34 FPS, which is far too low for an enjoyable experience in this genre. The data is clear: to get the best out of this hardware in Doom, one must play at 1080p and be willing to compromise on graphical settings.

CPU Role

The Intel Core i5-13400F is a capable processor that is severely underutilized in this pairing. It features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. It is built on Intel's Raptor Lake architecture and a 10 nm process node. The processor has a 20 MB shared L3 cache, and its benchmark scores are strong. In Cinebench R23, it scores 22604 in multi-core and 3191 in single-core. In Geekbench, it scores 11068 multi-core and 1996 single-core. These scores place the CPU in the 77th percentile of all CPUs, showing that it has ample processing power.

The CPU's nearest rivals in terms of average benchmark score are all comparable processors: the AMD Ryzen 9 6900HS (25284, 0% delta), Intel Core 5 120 (25362, -0.3% delta), AMD Ryzen 5 5600X3D (25365, -0.3% delta), and AMD Ryzen 7 6800H (25201, 0.4% delta). This shows the i5-13400F is competitive with other mid-range and even some high-end mobile processors. However, in this specific combo, the CPU's performance is irrelevant to the gaming outcome. The bottleneck is entirely on the GPU side. The data shows that the FPS is consistently low regardless of the CPU's capabilities. If the CPU were the limiting factor, we would see high FPS at low resolutions and a plateau at higher resolutions. Instead, we see a continuous decline in FPS as resolution increases, which is a clear indication that the Intel Arc B370 is maxed out. The i5-13400F is waiting for the GPU to catch up, and it never does.
