# How This Combo Ranks

The AMD Ryzen 5 7400F paired with the Intel Arc B370 lands at rank 2710 out of 2953 tested combinations in Rust. That places this combo in the bottom 8% of all tested systems, which is a striking result given the CPU's strong standalone credentials. The data suggests this pairing is heavily constrained by the graphics side, and the rank reflects a system that struggles to deliver playable frame rates in most scenarios.

The combo's position becomes clearer when examining the individual components. The Ryzen 5 7400F sits at the 83rd percentile among all CPUs, with an average benchmark score of 32750. Its nearest rivals include the Intel Core i5-14600T (avg score 32707, deltaPct 0.1), the Intel Core Ultra 7 155H (avg score 32697, deltaPct 0.2), and the AMD Ryzen 7 PRO 6850H (avg score 32812, deltaPct -0.2). These are all closely matched processors, with deltas under 0.3% — meaning the 7400F is squarely in the mid-to-upper tier of CPU performance. Yet the combo rank of 2710 indicates that the GPU is dragging the entire system down to near-bottom-tier status.

The Intel Arc B370's benchmark data tells a different story. Its 3DMark Steel Nomad DX12 score is 1184, placing it at the 5th percentile among all GPUs. Its nearest rivals are the ATI Mobility Radeon HD 5570 (avg score 1186, deltaPct -0.2), the ATI Radeon HD 5770 (avg score 1190, deltaPct -0.5), and the AMD Radeon HD 7650M (avg score 1192, deltaPct -0.7). These are all legacy or low-end mobile parts from a decade or more ago, and the Arc B370 essentially trades blows with them. This GPU is not just weak; it is historically weak by modern standards.

The gap between the CPU's 83rd percentile ranking and the GPU's 5th percentile ranking is enormous. In Rust, a game known for its CPU-heavy simulation and world persistence, one might expect the processor to carry the system. But the measured FPS data shows that even the CPU's strength cannot overcome the GPU's fundamental limitations. The combo rank of 2710 is a direct consequence of this mismatch, and the data implies that any upgrade path must start with the graphics component.

GPU Role

The Intel Arc B370 is an integrated graphics solution based on the Panther Lake chip, using the Xe3-LPG architecture on Intel's 3 nm process. Its clock speeds are modest: a base clock of 300 MHz and a boost clock of 2400 MHz. The memory configuration is listed as "System Shared" for size, type, and bus width, with bandwidth described as "System Dependent." This means the GPU borrows from system memory rather than having dedicated VRAM, which is a critical constraint for a game like Rust that can be memory-hungry at higher settings.

The GPU has 1280 shading units, 40 texture mapping units, and 20 raster output units. It also includes 10 ray tracing cores. The pixel rate is 48.00 GPixel/s, and the texture rate is 96.00 GTexel/s. The FP32 performance is 6.144 TFLOPS, with FP16 at 12.29 TFLOPS (2:1). These specifications are consistent with an entry-level integrated solution, and the 25 W TDP confirms this is not designed for heavy gaming workloads.

In Rust, the GPU's role becomes apparent when examining the FPS scaling across settings. At 3840x2160, the average FPS drops from 28 on Low to 16 on High, and further to 12 on Ultra. The Medium preset at 4K yields 19 FPS with a minimum of 16 and maximum of 22. These numbers indicate that the Arc B370 is overwhelmed at 4K regardless of settings. Even at Low, 28 FPS is below the playable threshold for most gamers, and the data shows the GPU is the limiting factor.

At 2560x1440, the situation improves slightly but remains poor. Low settings produce 48 FPS, Medium drops to 32 FPS (min 27, max 37), High yields 27 FPS, and Ultra falls to 20 FPS. The progression from Low to Ultra shows a consistent decline of roughly 58% from the lowest to highest preset. This scaling pattern suggests the GPU's shading units and memory bandwidth are insufficient for the increased workload at higher settings.

The 1080p results are the only ones approaching playability. Low settings hit 69 FPS, Medium reaches 46 FPS (min 39, max 53), High manages 39 FPS, and Ultra drops to 30 FPS. Even at 1080p, the Ultra preset barely maintains 30 FPS, which is unsustainable for a competitive survival game. The GPU's performance ceiling is clearly around 1080p Low to Medium, and anything beyond that pushes the hardware past its limits.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor from the 7000 series, built on Zen 4 architecture with the Raphael codename. It uses a 5 nm process from TSMC, with a die size of 71 mm² and 6,570 million transistors. The base clock is 3.70 GHz, and the boost clock reaches 4.70 GHz. The TDP is 65 W, and it supports DDR5 memory with a dual-channel bus, providing 83.2 GB/s of memory bandwidth. The L3 cache is 32 MB shared, with 1 MB L2 per core and 64 KB L1 per core.

Benchmark results show this CPU is a capable performer. In Cinebench R23, it scores 21765 in multi-core and 3072 in single-core. Cinebench R20 yields 9141 multi-core and 1290 single-core. Cinebench R15 produces 2193 multi-core and 309 single-core. PassMark results include a multi-thread score of 25645, a single-thread score of 3689, and a physics score of 1660. The data compression score is 289999, and integer math reaches 74745. These numbers place the CPU in the top 17% of all processors, which is respectable for a 6-core part.

In Rust, the CPU's role is typically significant because the game simulates a persistent world with many entities, building structures, and player actions. The 7400F's 6 cores and 12 threads, combined with the 32 MB L3 cache, should handle these workloads reasonably well. However, the measured FPS data shows that the CPU's potential is not being realized. At 1080p Low, where the GPU has the least work, the system achieves 69 FPS. This suggests the CPU can push frames when the graphics load is minimal, but the Arc B370 cannot sustain higher output.

The CPU's single-core performance is particularly relevant for Rust, which often relies on a primary simulation thread. The Cinebench R23 single-core score of 3072 is strong, and the PassMark single-thread score of 3689 confirms this. Yet at 1440p and 4K, the FPS drops are steep even at Low settings, indicating that the GPU becomes the bottleneck well before the CPU's limits are reached. The data implies that the CPU has headroom to spare, but the integrated GPU cannot keep up.

Measured FPS Breakdown

The measured FPS data provides a clear picture of this combo's limitations across resolutions and settings. At 1920x1080, the system delivers 69 FPS on Low, 46 FPS on Medium (with a minimum of 39 and maximum of 53), 39 FPS on High, and 30 FPS on Ultra. The gap between Low and Ultra is 39 FPS, a 57% reduction, which demonstrates how quickly the GPU performance degrades as settings increase.

Moving to 2560x1440, the averages drop to 48 FPS on Low, 32 FPS on Medium (min 27, max 37), 27 FPS on High, and 20 FPS on Ultra. The reduction from 1080p to 1440p at Low settings is 21 FPS (69 to 48), a 30% decline. At Medium, the drop is 14 FPS (46 to 32), a 30% decline. At High, the drop is 12 FPS (39 to 27), a 31% decline. At Ultra, the drop is 10 FPS (30 to 20), a 33% decline. These consistent percentage drops indicate that the GPU is scaling predictably with resolution, but from an already low base.

At 3840x2160, the results are largely unplayable. Low settings produce 28 FPS, Medium yields 19 FPS (min 16, max 22), High drops to 16 FPS, and Ultra falls to 12 FPS. The decline from 1440p to 4K at Low settings is 20 FPS (48 to 28), a 42% reduction. At Medium, the drop is 13 FPS (32 to 19), a 41% reduction. At High, the drop is 11 FPS (27 to 16), a 41% reduction. At Ultra, the drop is 8 FPS (20 to 12), a 40% reduction. The uniformity of these declines across settings suggests the GPU is consistently bandwidth or compute-limited at 4K.

The minimum and maximum FPS values are only provided for the Medium preset at each resolution. At 1080p Medium, the range is 39 to 53 FPS, a 14 FPS spread. At 1440p Medium, the range is 27 to 37 FPS, a 10 FPS spread. At 4K Medium, the range is 16 to 22 FPS, a 6 FPS spread. The narrowing range at higher resolutions indicates that the GPU is becoming more consistently saturated, leaving less room for variance.

FAQ

These are all within 0.7% of the Arc B370's score, indicating it performs at a similar level to these older parts.

Q: Is the CPU or GPU the bottleneck in this system?

A: The data strongly indicates the GPU is the bottleneck. The Ryzen 5 7400F ranks in the 83rd percentile among CPUs, while the Arc B370 ranks in the 5th percentile among GPUs. The FPS drops by roughly 30% from 1080p to 1440p and another 40% from 1440p to 4K, which is characteristic of GPU limitation rather than CPU constraint.

Q: What settings preset provides the best balance of FPS and visual quality?

A: At 1080p, the Medium preset offers 46 FPS with a minimum of 39 and maximum of 53, which is the highest average FPS among presets above Low. The Low preset at 69 FPS is smoother but sacrifices visual fidelity. The data suggests Medium at 1080p is the highest quality setting that maintains a reasonable frame rate.

Q: How does the Ryzen 5 7400F compare to its nearest CPU rivals?

A: The Ryzen 5 7400F has an average benchmark score of 32750. The Intel Core i5-14600T scores 32707 (deltaPct 0.1), the Intel Core Ultra 7 155H scores 32697 (deltaPct 0.2), and the AMD Ryzen 7 PRO 6850H scores 32812 (deltaPct -0.2). These deltas are all under 0.3%, meaning the 7400F is essentially equivalent to these processors in average performance.

Q: Can this combo handle Rust at 4K under any settings?

A: No. At 3840x2160, even the Low preset only achieves 28 FPS on average. The Medium preset drops to 19 FPS, High to 16 FPS, and Ultra to 12 FPS. None of these results are playable for a survival game that requires quick reactions and sustained engagement.

Settings Recommendations

Based on the measured FPS data, the only viable settings for this combo are at 1920x1080 resolution. The Low preset delivers 69 FPS on average, which is smooth and responsive for Rust's gameplay mechanics. However, the visual quality at Low may obscure distant objects or player-built structures, which could be a disadvantage in a survival context where situational awareness matters.

The Medium preset at 1080p offers 46 FPS on average, with a minimum of 39 and maximum of 53. This is a more balanced option, providing better visual detail while maintaining a frame rate that is above the 30 FPS threshold commonly considered the minimum for playability. The 39 FPS minimum is concerning but likely acceptable for most sessions, especially if the player is not in heavy combat or near large bases with many entities.

At 1440p, only the Low preset approaches playability with 48 FPS. The Medium preset at 32 FPS is borderline, and the minimum of 27 FPS suggests it will drop below 30 during intense moments. The High and Ultra presets at 27 and 20 FPS respectively are not recommended for any serious gameplay.

At 4K, no preset is playable. The Low preset at 28 FPS is the best result, but it still falls short of the 30 FPS minimum standard. Players who own a 4K monitor should consider running the game at a lower resolution, as the data shows the GPU cannot handle Rust at this resolution under any settings.

The best experience per the measured rows is 1080p Medium. It offers a combination of visual fidelity and frame rate that is superior to Low while avoiding the severe performance penalties of High and Ultra. The 46 FPS average is respectable, and the 39 FPS minimum is acceptable for most gameplay scenarios.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals important information about where the bottleneck lies. At Low settings, the average FPS drops from 69 at 1080p to 48 at 1440p (a 30% reduction) and then to 28 at 4K (a 42% reduction from 1440p). At Medium settings, the progression is 46 to 32 to 19, with reductions of 30% and 41%. At High, it goes from 39 to 27 to 16, with reductions of 31% and 41%. At Ultra, it drops from 30 to 20 to 12, with reductions of 33% and 40%.

The consistency of these percentage drops across all settings is significant. If the CPU were the bottleneck, we would expect to see the FPS remain relatively flat as resolution increases, because the CPU's workload is largely resolution-independent. Instead, the FPS drops by roughly 30% from 1080p to 1440p and another 40% from 1440p to 4K, which is exactly the pattern we would expect from a GPU that is fully saturated and cannot keep up with the increasing pixel count.

The data also shows that the gap between Low and Ultra settings narrows as resolution increases. At 1080p, the difference between Low and Ultra is 39 FPS. At 1440p, it is 28 FPS. At 4K, it is 16 FPS. This narrowing indicates that at higher resolutions, the GPU is so overwhelmed that even reducing settings provides diminishing returns. The GPU is running out of raw throughput, and lower settings cannot compensate for the sheer number of pixels being rendered.

This scaling behavior strongly suggests that the Intel Arc B370 is the limiting component. The CPU's strong single-thread performance and high percentile ranking are irrelevant when the GPU cannot render frames fast enough. If the GPU were replaced with a more capable part, the FPS would likely scale much better with resolution, and the CPU's headroom would become apparent. As it stands, the data shows a system where a powerful processor is hamstrung by an integrated GPU that belongs to a much older performance class.
