Rust

The AMD Ryzen 7 5700 and Intel Arc B370 combination delivers a playable experience in Rust, but the data shows that this pairing is heavily constrained by the graphics processor. The Arc B370, which sits in the 5th percentile of all GPUs, produces frame rates that range from 12 FPS at 4K Ultra to 69 FPS at 1080p Low. While the 8-core, 16-thread Ryzen 7 5700 provides solid CPU-side performance, the Arc B370’s shared-memory architecture and low throughput make it the clear bottleneck in nearly every scenario. This system is only suitable for 1080p gaming, and even then, only at lower settings presets.

FAQ

Q: What is the best resolution to use with this combo?

A: 1920x1080. The measured data shows that this is the only resolution where the average FPS exceeds 60, and that only happens at the Low preset (69 FPS). At 2560x1440, all settings presets produce averages below 48 FPS, and at 3840x2160, the highest average is just 28 FPS (Low preset).

Q: How does the Arc B370 compare to its nearest GPU rivals?

A: The Arc B370’s average benchmark score of 1184 is nearly identical to the ATI Mobility Radeon HD 5570 (1186) and the ATI Radeon HD 5770 (1190), with delta percentages of -0.2% and -0.5% respectively. It is only 1.4% faster than the AMD FirePro M2000 (1168). These are all legacy or low-end parts, indicating the B370 is not a high-performance gaming GPU.

Q: Is the Ryzen 7 5700 a strong CPU for this game?

A: Yes, relative to other CPUs, the Ryzen 7 5700 performs well. It sits in the 78th percentile of all CPUs, and its average benchmark score of 25517 is nearly identical to the AMD Ryzen 5 7640U (25485) and the Intel Xeon D-2752TER (25530). The CPU has ample headroom, but the GPU limits the overall frame rate.

Q: What is the highest FPS this combo can achieve in Rust?

A: According to the measured data, the maximum average FPS is 69, which occurs at 1920x1080 with the Low settings preset. The next highest is 48 FPS at 2560x1440 Low. There are no measured frame rates above 69 FPS for any resolution or settings combination.

Q: Should I use the Ultra settings preset?

A: No. The Ultra preset yields the lowest frame rates across all resolutions. At 1920x1080, it averages 30 FPS; at 2560x1440, it drops to 20 FPS; and at 3840x2160, it falls to 12 FPS. These numbers are generally too low for smooth gameplay in a fast-paced survival game.

Q: Does this combo rank well compared to other tested systems?

A: No. The combo rank in game is 2710 out of 2953 tested combos. This places it in the bottom 8% of all combinations, which is consistent with the GPU’s low percentile ranking and the low measured FPS.

CPU Role

The Ryzen 7 5700 is a capable desktop processor from AMD’s 5000 series, built on the Zen 3 architecture (codenamed Cezanne) using a 7 nm process. It provides 8 cores and 16 threads, with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. This configuration is more than sufficient for Rust’s CPU demands, which typically involve handling many entities, player interactions, and world simulations. The CPU’s 16 threads allow it to manage these parallel workloads effectively.

In synthetic benchmarks, the Ryzen 7 5700 shows strong multi-threaded performance. It scores 20655 in Cinebench R23 multicore, 8675 in Cinebench R20 multicore, and 2082 in Cinebench R15 multicore. The Geekbench multicore score is 9959, and the Passmark multithread score is 24303. More importantly for gaming, its single-thread performance is solid as well, with a Geekbench singlecore score of 1907 and a Passmark single thread score of 3296. Rust is known to be sensitive to single-thread performance, so the Ryzen 7 5700’s decent single-core scores help maintain minimum frame rates.

The CPU’s 16 MB of L3 cache and 512 KB of L2 cache per core provide fast access to frequently used data, which is beneficial for the game’s physics and AI calculations. The CPU supports DDR4 memory with a dual-channel bus, offering 51.2 GB/s of bandwidth. It also supports ECC memory, which is a stability feature not common in all consumer CPUs.

However, the data suggests that the CPU is not the limiting factor in this pairing. The Ryzen 7 5700’s percentile rank is 78, meaning it outperforms 78% of all CPUs. In contrast, the GPU’s percentile is 5, meaning it outperforms only 5% of all GPUs. This significant gap indicates that the CPU is waiting on the GPU to render frames, not the other way around. The measured FPS numbers across all resolutions and settings are consistent with a GPU bottleneck, as they scale predictably with resolution and graphical load, rather than with CPU-heavy tasks.

GPU Role

The Intel Arc B370 is the definitive bottleneck in this combo. This integrated-style GPU, based on the Xe3-LPG architecture (chip codenamed Panther Lake), has a 25 W TDP and uses system shared memory. Its performance is extremely limited, placing it in the 5th percentile of all GPUs. The only benchmark score provided is 1184 in 3DMark Steel Nomad DX12, which is nearly identical to the scores of the ATI Radeon HD 5770 (1190) and the ATI Mobility Radeon HD 5570 (1186). These rivals are from a much older generation, showing how far behind the B370 is compared to modern discrete GPUs.

The GPU has 1280 shading units, 40 TMUs, and 20 ROPs. It also includes 10 ray tracing cores, though its raw compute performance is low. The FP32 performance is rated at 6.144 TFLOPS, and the pixel rate is 48.00 GPixel/s. The boost clock is 2400 MHz, but the memory bandwidth is labeled "System Dependent" because it uses system RAM. This shared memory architecture means the GPU is competing with the CPU for memory bandwidth, which further hurts performance in memory-intensive games like Rust.

The data shows that the Arc B370 cannot handle high resolutions or high settings in Rust. At 3840x2160, the average FPS drops to 16 at High settings and 12 at Ultra settings. Even at the Low preset, 4K only yields 28 FPS. At 2560x1440, the results are better but still not great: 48 FPS at Low, 32 FPS at Medium, and 27 FPS at High. The only playable scenario is at 1920x1080, where the Low preset reaches 69 FPS and the Medium preset achieves 46 FPS. The High preset at 1080p drops to 39 FPS, which is borderline.

The GPU’s low ROP count (20) and low pixel rate (48 GPixel/s) are likely the reasons for the poor performance at higher resolutions. The texture rate of 96 GTexel/s is also modest, which affects how quickly textures can be applied to surfaces. In Rust, which has large open-world environments with many objects, these limitations become apparent quickly.

Settings Recommendations

Based on the measured FPS data, the only settings preset that delivers a consistently smooth experience at a standard resolution is Low at 1920x1080. This preset yields an average of 69 FPS, which is above the 60 FPS threshold typically considered comfortable for most players. The Medium preset at 1080p (46 FPS) is playable but may feel slightly less fluid, especially in busy areas with many players or structures.

For users with 2560x1440 monitors, the Low preset is the only viable option, producing 48 FPS. The Medium preset at 1440p drops to 32 FPS, which is below the 60 FPS mark and may cause noticeable stuttering in combat scenarios. The High and Ultra presets at 1440p are not recommended, as they produce 27 FPS and 20 FPS respectively.

At 3840x2160, none of the presets are suitable for gameplay. The highest average FPS is 28 (Low), which is below the playable threshold for a fast-paced survival game. The Ultra preset at 4K (12 FPS) is effectively a slideshow. As such, 4K gaming is not viable with this combo.

The data suggests that users should prioritize frame rate over visual fidelity. Starting at 1080p Low and adjusting settings upward is the best approach. The Medium preset at 1080p offers a good balance of visuals and performance, with an average of 46 FPS and a minimum of 39 FPS. However, for competitive play or busy servers, sticking with Low is the safer choice. The gap between Low (69 FPS) and Medium (46 FPS) is substantial, a 33% drop that may not be worth the visual improvement given the GPU’s limitations.

How This Combo Ranks

The combination of the AMD Ryzen 7 5700 and the Intel Arc B370 ranks 2710th out of 2953 tested combos for Rust. This places it in the bottom 8% of all systems tested, which is a poor showing. The GPU’s low performance is the primary reason for this ranking, as it drags down the entire system despite the CPU’s solid performance.

The Ryzen 7 5700’s nearest CPU rivals include the Intel Xeon D-2752TER (avg score 25530, delta -0.1%), the AMD Ryzen 5 7640U (avg score 25485, delta 0.1%), and the AMD Ryzen 5 6600H (avg score 25550, delta -0.1%). These CPUs all perform within 0.3% of each other, showing that the Ryzen 7 5700 is a middle-of-the-pack processor in terms of raw benchmark scores. However, its percentile of 78 indicates it is better than most CPUs on the market.

The GPU’s nearest rivals paint a different picture. The Arc B370’s score is nearly tied with the ATI Mobility Radeon HD 5570 (1186) and the ATI Radeon HD 5770 (1190), but it is 1.4% faster than the AMD FirePro M2000 (1168). These are all older or low-end parts, confirming that the B370 is not a serious gaming GPU. The combo’s low rank is directly attributable to this GPU performance.

The data shows that pairing a high-percentile CPU with a low-percentile GPU results in a system that is unbalanced for gaming. The Ryzen 7 5700 has the compute power to handle Rust’s simulation, but the Arc B370 cannot render frames fast enough to take advantage of it. This is a classic case where upgrading the GPU would yield far greater performance gains than upgrading the CPU.

Measured FPS Breakdown

The measured FPS data provides a clear picture of the system’s capabilities across different resolutions and settings. At 3840x2160, the system produces an average of 16 FPS at High settings, 28 FPS at Low, 19 FPS at Medium, and 12 FPS at Ultra. The Medium preset has minimum and maximum values of 16 and 22 FPS, respectively. These numbers are all far below playable levels.

At 2560x1440, performance improves but remains limited. The High preset averages 27 FPS, the Low preset averages 48 FPS, and the Medium preset averages 32 FPS with a range of 27 to 37 FPS. The Ultra preset averages 20 FPS. While the Low preset is technically playable, it is not a comfortable experience for most users.

At 1920x1080, the system shows its best performance. The High preset averages 39 FPS, the Low preset averages 69 FPS, and the Medium preset averages 46 FPS with a range of 39 to 53 FPS. The Ultra preset averages 30 FPS. The 1080p Low preset is the only configuration that exceeds 60 FPS on average, making it the recommended choice. The Medium preset is a secondary option if visual quality is more important, but it comes at a significant cost to frame rate.

The scaling between presets is consistent across resolutions. The Low preset always provides the highest FPS, followed by Medium, then High, and finally Ultra. The gap between Low and Ultra is substantial; at 1080p, the difference is 39 FPS (69 vs 30). The resolution scaling also follows a predictable pattern, with 1080p being roughly 1.4 to 1.5 times faster than 1440p at the same settings, and 1440p being roughly 1.6 to 1.8 times faster than 4K. This indicates that the GPU is heavily resolution-bound, reinforcing the conclusion that this combo is only suitable for 1080p gaming.
