Rust

Rust, the 2018 survival game, is notoriously demanding on both CPU and GPU, but this particular pairing is lopsided. The AMD Ryzen 9 9950X3D is a 16-core, 32-thread desktop processor built on Zen 5 (Granite Ridge) at TSMC's 4 nm node, ranking in the 95th percentile of all CPUs. The Intel Arc B370 is an integrated GPU based on Xe3-LPG architecture at Intel's 3 nm node, ranking in the 5th percentile of all GPUs. The measured frame rates reflect that imbalance: only one preset at 1920x1080 reaches the 60 FPS playable threshold.

Best Settings per Resolution

At 3840x2160, no preset comes close to 60 FPS. The best average is 28 FPS at Low settings. Medium averages 19 FPS (min 16, max 22), High averages 16 FPS, and Ultra averages 12 FPS. Since every preset falls well short of the 60 FPS playable threshold, there is no recommended setting at 4K.

At 2560x1440, the situation is similar. Low averages 48 FPS, Medium averages 32 FPS (min 27, max 37), High averages 27 FPS, and Ultra averages 20 FPS. None reach 60 FPS, so no playable setting exists at 1440p.

At 1920x1080, the Low preset is the only one that clears the threshold, averaging 69 FPS. Medium averages 46 FPS (min 39, max 53), High averages 39 FPS, and Ultra averages 30 FPS. Low is therefore the most demanding preset that stays at or above 60 FPS, and the only playable option at this resolution. The gap between Low and Medium at 1080p, from 69 to 46 FPS, shows how quickly the GPU becomes overwhelmed as rendering quality increases.

CPU and GPU Roles

The Ryzen 9 9950X3D brings flagship specifications: 16 cores, 32 threads, a base clock of 4.30 GHz, a boost clock of 5.70 GHz, a 170 W TDP, and 128 MB of L3 cache. Its launch MSRP is $699. The CPU supports DDR5 memory over a dual-channel bus with 89.6 GB/s of bandwidth, and it connects via PCIe Gen 5 with 24 lanes. Its average benchmark score of 75779 places it in the 95th percentile of all CPUs, with a Cinebench R23 multicore score of 42018 and a singlecore score of 2259.

The Arc B370, by contrast, is an integrated GPU with 1280 shading units, 40 texture mapping units, 20 raster output units, and 10 ray tracing cores. It has a 25 W TDP and a pixel rate of 48.00 GPixel/s, with a texture rate of 96.00 GTexel/s and FP32 performance of 6.144 TFLOPS. Its average benchmark score of 1184 places it in the 5th percentile of all GPUs.

The recorded data shows that the GPU is the binding constraint. At Low settings, the game runs at 69 FPS at 1080p, 48 FPS at 1440p, and 28 FPS at 4K. The steep decline with each resolution step is the signature of a GPU-bound workload. Within a resolution, raising the preset has a similar effect. At 1080p, the average goes from 69 FPS at Low to 46 FPS at Medium, then 39 FPS at High, and 30 FPS at Ultra. At 1440p, the spread is 48 to 32 to 27 to 20. At 4K, it is 28 to 19 to 16 to 12. These consistent drops track the GPU's rendering load, not CPU capability.

The CPU's headroom is evident from its benchmark standing. A 95th percentile CPU paired with a 5th percentile GPU means the processor is effectively waiting on graphics work. Any attempt to improve frame rates would require a stronger GPU; swapping the CPU would change nothing in this configuration.

Measured FPS Breakdown

At 1920x1080, the measured averages are: Low 69 FPS, Medium 46 FPS (min 39, max 53), High 39 FPS, and Ultra 30 FPS.

At 2560x1440, the averages are: Low 48 FPS, Medium 32 FPS (min 27, max 37), High 27 FPS, and Ultra 20 FPS.

At 3840x2160, the averages are: Low 28 FPS, Medium 19 FPS (min 16, max 22), High 16 FPS, and Ultra 12 FPS.

Min and max values are only recorded for the Medium preset at each resolution. The 1080p Medium range of 39 to 53 FPS shows that even the best-case frame time stays below the 60 FPS threshold, and the 4K Medium range of 16 to 22 FPS demonstrates how far this GPU is from playable at high pixel counts. The 1440p Medium range of 27 to 37 FPS sits between those two extremes, consistent with the resolution scaling seen across all presets.

How This Combo Ranks

In the database's measured combinations, this pairing ranks 3437th out of 3723. That places it in the lowest portion of the field, consistent with the GPU's 5th percentile standing. The CPU's 95th percentile ranking does not rescue the overall result, because Rust's frame rate in this configuration is dictated entirely by the GPU. The rank reflects the combined system performance, and the GPU drags the pairing down to the bottom of the distribution.

Similar Performance Alternatives

The CPU's nearest rivals, based on average benchmark score, are all within a fraction of a percent. The AMD Ryzen 7 PRO 9755 is 0.1% higher, the AMD Ryzen 7 PRO 9755X3D is 0.1% higher, the AMD EPYC 8224P is 0.3% higher, and the Intel Core Ultra 9 285 is 0.4% higher. Swapping the 9950X3D for any of these would produce essentially identical CPU-side behavior in Rust.

The GPU's nearest rivals are similarly close. The ATI Mobility Radeon HD 5570 is 0.2% lower in average score, the ATI Radeon HD 5770 is 0.5% lower, the AMD Radeon HD 7650M is 0.7% lower, and the AMD FirePro M2000 is 1.4% higher. None of these would meaningfully change the measured frame rates in this game.

For a system builder looking at the recorded data, the CPU can be swapped among these near-identical alternatives without affecting the outcome. The GPU, however, has no nearby alternative that would push Rust past the 60 FPS threshold at higher resolutions.
