Rust

The AMD Ryzen 5 2600 and Intel Arc B390 combination presents a stark contrast in processor and graphics capability. The CPU is a solid mid-range part from 2018, while the GPU, an integrated graphics solution from Intel's Panther Lake platform, ranks near the bottom of the database. Benchmark results indicate this pairing is severely limited by the graphics side, with playable performance confined to 1080p with the lowest settings.

Similar Performance Alternatives

The CPU and GPU in this pairing occupy very different positions in the performance hierarchy. The Ryzen 5 2600 sits at the 75th percentile among all CPUs, with an average benchmark score of 21,484. Its nearest rivals in the database are the Intel Core Ultra 5 228V with an average score of 21,440 (0.2% faster), the Intel Core i9-11900H at 21,367 (0.5% faster), and the Intel Xeon D-1746TER at 21,635 (0.7% slower). The AMD EPYC 9454 also appears nearby at 21,223, which is 1.2% slower. These figures show that the Ryzen 5 2600 remains competitive with much newer processors in synthetic workloads, particularly in multi-threaded tests where its 6 cores and 12 threads deliver a PassMark multithread score of 13,160.

The Intel Arc B390 tells a different story. Its average benchmark score is just 1,482 from the 3DMark Steel Nomad DX12 test, placing it at the 9th percentile of all GPUs. The nearest rivals are all legacy NVIDIA parts: the GeForce GT 520MX at 1,463 (1.3% slower), the GeForce 800M at 1,460 (1.5% slower), the GeForce GT 625 OEM at 1,446 (2.5% slower), and the GeForce GT 710 at 1,443 (2.7% slower). This places the Arc B390 firmly in entry-level territory, comparable to integrated graphics solutions from over a decade ago. The GPU's 1,536 shading units and 7.680 TFLOPS of FP32 performance are technically capable, but the system-shared memory and lack of dedicated VRAM create a significant bottleneck.

For users considering alternatives, any CPU within a few percent of the Ryzen 5 2600's average score would behave similarly in CPU-bound scenarios. Conversely, the GPU's performance class means that any of its nearest rivals would produce nearly identical frame rates in Rust, assuming the rest of the system remains unchanged.

CPU and GPU Roles

The recorded data shows that the Intel Arc B390 is the dominant constraint in this pairing across all resolutions. At 1920x1080, the difference between Low and Ultra settings is substantial: 76 FPS average on Low versus 33 FPS on Ultra. This 43 FPS gap indicates that the GPU is struggling with the increased rendering load at higher presets. The CPU, with its 16 MB of shared L3 cache and 46.9 GB/s memory bandwidth, is likely not the primary limitation at 1080p, as even the most demanding preset still produces playable frame rates.

At 2560x1440, the GPU constraint becomes more pronounced. The average FPS drops from 53 on Low to 23 on Ultra, a 30 FPS reduction. The scaling from 1080p to 1440p at the same settings shows a clear GPU-bound pattern: Low settings drop from 76 to 53 FPS (a 30% reduction), Medium from 51 to 35 FPS (31% reduction), High from 43 to 30 FPS (30% reduction), and Ultra from 33 to 23 FPS (30% reduction). This consistent percentage decline across all presets indicates that the resolution increase is directly taxing the GPU's fill rate and memory bandwidth.

At 3840x2160, the situation becomes critical. Low settings produce only 31 FPS average, and every other preset falls below 21 FPS. The GPU's 24 ROPs and 60.00 GPixel/s pixel rate are insufficient for 4K rendering in Rust. The CPU's role at this resolution is minimal; even if the Ryzen 5 2600 were replaced with a significantly faster processor, the frame rates would not improve meaningfully because the GPU is already saturated. The data shows that the CPU matters most at 1080p Low, where the 76 FPS average suggests the GPU can keep up with the lower workload, but the CPU's single-thread performance (PassMark single thread score of 2,239) may start to become a factor in CPU-heavy scenes.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this combination's performance across resolutions and presets.

At 1920x1080, the only playable setting is Low, which delivers an average of 76 FPS. Medium settings produce 51 FPS average with a minimum of 44 and maximum of 59, which falls short of the 60 FPS playable threshold. High settings drop to 43 FPS average, and Ultra delivers 33 FPS average. The gap between Low and Ultra is 43 FPS, representing a 57% performance loss when moving to the highest preset.

At 2560x1440, no preset reaches the 60 FPS threshold. Low settings deliver 53 FPS average, which is close but not sufficient. Medium produces 35 FPS average with a minimum of 30 and maximum of 41, High drops to 30 FPS, and Ultra falls to 23 FPS. The scaling from 1080p to 1440p costs roughly 30% of the frame rate at every preset, confirming that the GPU is the limiting factor.

At 3840x2160, performance is severely limited. Low settings achieve 31 FPS average, Medium produces 21 FPS with a minimum of 18 and maximum of 24, High delivers 18 FPS, and Ultra drops to 13 FPS. None of these results approach the 60 FPS threshold, and even the least demanding preset is below 32 FPS. The data indicates that 4K gaming is not viable with this hardware combination in Rust.

The measured FPS values with min/max data are sparse, but the Medium preset at each resolution includes full ranges: 44 to 59 FPS at 1080p, 30 to 41 FPS at 1440p, and 18 to 24 FPS at 4K. These ranges show that frame pacing is relatively stable, with the spread between minimum and maximum being 15 FPS or less in all cases.

How This Combo Ranks

This specific combination of AMD Ryzen 5 2600 and Intel Arc B390 ranks 3,312 out of 3,723 tested combos for Rust. This places it in the bottom 11% of all configurations in the database. The low ranking is almost entirely attributable to the GPU, which is in the 9th percentile of all GPUs. The CPU's 75th percentile ranking indicates that the processor is not the limiting factor, but the integrated graphics solution drags the entire system down.

The rank of 3,312 means that over 3,700 other hardware combinations deliver better performance in Rust. The gap between this combo and more balanced pairings is significant. For context, the GPU's nearest rivals are all over a decade old, and the measured FPS data shows that even at 1080p Low, the system barely exceeds the 60 FPS threshold with a 76 FPS average. The combination's position in the bottom 11% suggests that users seeking a smoother experience would need to consider a dedicated graphics card, as the CPU has headroom to support one.

Best Settings per Resolution

At 1920x1080, the best playable setting is Low, which delivers an average of 76 FPS. This is the only preset that meets or exceeds the 60 FPS playable threshold. Medium settings come close at 51 FPS average, but the minimum of 44 FPS indicates that frame drops would be noticeable during intense gameplay. High and Ultra settings produce 43 and 33 FPS respectively, making them unsuitable for smooth play.

At 2560x1440, no settings are playable. The best result is Low at 53 FPS average, which falls 7 FPS short of the 60 FPS threshold. The data shows that even with the lowest settings, the Intel Arc B390 cannot maintain playable frame rates at this resolution. Medium, High, and Ultra produce 35, 30, and 23 FPS respectively, all well below the threshold.

At 3840x2160, no settings are playable. Low settings achieve only 31 FPS average, which is less than half of the 60 FPS threshold. Medium produces 21 FPS, High 18 FPS, and Ultra 13 FPS. The 4K resolution is far beyond the capabilities of this GPU, and users should not expect any preset to provide a playable experience at this resolution.

The verdict data confirms this analysis: the only playable setting across all resolutions is 1080p Low, with an average FPS of 76. For users willing to accept lower frame rates, 1440p Low at 53 FPS is the closest alternative, but it does not meet the playable threshold defined by the database. This combination is best suited for 1080p gaming with minimal graphical demands, and even then, users should expect to compromise on visual quality to maintain playable performance.
