# How This Combo Ranks

The AMD Ryzen 5 5600G paired with the Intel Arc B390 lands at rank 2601 out of 2953 tested combos in Rust. That places this configuration in the bottom 12% of all tested combinations, a result that reflects the Arc B390's position as an integrated graphics solution rather than a dedicated gaming card. The data shows this combo trailing the vast majority of tested systems, with only 352 other combinations performing worse in this survival title.

Benchmark results indicate that the combo's ranking is heavily constrained by the GPU side of the equation. The Arc B390 sits at the 9th percentile among all GPUs in the database, with an average benchmark score of 1482 in 3DMark Steel Nomad DX12. This places it in direct competition with legacy NVIDIA parts like the GeForce GT 520MX, which scores 1463 (1.3% lower), and the GeForce GT 710, which scores 1443 (2.7% lower). The CPU, meanwhile, performs far more respectably — the Ryzen 5 5600G sits at the 74th percentile among all CPUs, with an average benchmark score of 21088. This massive disparity between CPU and GPU capability is the defining characteristic of this combo.

The practical implication is that Rust's performance here will be dictated almost entirely by the integrated GPU. Players can expect playable frame rates only at lower resolutions and settings, while higher configurations will struggle to maintain smooth gameplay. The combo's rank of 2601 out of 2953 reflects this GPU bottleneck, and the measured frame rates confirm that this pairing is best suited for modest gaming expectations.

GPU Role

The Intel Arc B390 is an integrated graphics processor built on the Xe3-LPG architecture, using a 3 nm process from Intel. It features 1536 shading units, 48 texture mapping units, and 24 raster operation units, along with 12 ray tracing cores. The GPU operates at a base clock of 300 MHz and boosts up to 2500 MHz, with a TDP of 80 W. Its memory configuration is entirely system-shared, meaning it draws from the host system's DDR4 memory rather than having dedicated VRAM. The memory bus width and bandwidth are similarly system-dependent, with the bandwidth labeled as "System Dependent."

In Rust, this GPU's performance profile is clearly limited. At 1080p with Low settings, the combo achieves 76 FPS on average, which is the only measured result that approaches smooth gameplay. Every other configuration falls below 60 FPS, with Ultra settings at 1080p dropping to 33 FPS. At 1440p, the numbers decline further: Low settings yield 53 FPS, Medium drops to 35 FPS, and Ultra falls to 23 FPS. At 4K, the GPU is overwhelmed — even Low settings only produce 31 FPS, while Ultra settings manage just 13 FPS.

The GPU's nearest rivals in the benchmark database are all legacy NVIDIA parts, which underscores its position in the performance hierarchy. The GeForce GT 520MX is 1.3% slower, the GeForce 800M is 1.5% slower, the GeForce GT 625 OEM is 2.5% slower, and the GeForce GT 710 is 2.7% slower. These are all parts from a bygone era of mobile and entry-level desktop graphics, and the Arc B390's placement among them confirms that it offers roughly a decade-old level of gaming performance despite its modern architecture.

The GPU's pixel rate is 60.00 GPixel/s and its texture rate is 120.0 GTexel/s, with FP32 performance of 7.680 TFLOPS. These figures are modest by modern standards, and Rust's demanding rendering workload exposes these limitations clearly. The ray tracing cores are present, but the overall GPU performance is too low for them to meaningfully influence gameplay in this title.

Resolution Scaling

The measured frame rates show a predictable and steep decline as resolution increases, but the pattern reveals important details about which component is limiting performance. From 1080p to 1440p, the average FPS drops by roughly 30-40% depending on settings. At Low settings, the drop is from 76 FPS to 53 FPS, a 30% reduction. At High settings, the drop is from 43 FPS to 30 FPS, a 30% reduction. At Ultra settings, the drop is from 33 FPS to 23 FPS, a 30% reduction.

From 1440p to 4K, the decline continues but becomes even more severe. At Low settings, the drop is from 53 FPS to 31 FPS, a 42% reduction. At High settings, the drop is from 30 FPS to 18 FPS, a 40% reduction. At Ultra settings, the drop is from 23 FPS to 13 FPS, a 43% reduction. The consistency of these percentage drops across settings strongly indicates that the GPU is the limiting factor at all resolutions — if the CPU were the bottleneck, the frame rate would remain relatively flat as resolution increases.

The data supports this conclusion further when examining the absolute numbers. At 1080p Low, the combo reaches 76 FPS, which suggests the CPU can feed frames at a rate well above what the GPU can sustain at higher resolutions. If the CPU were the constraint, we would expect to see a ceiling around this 76 FPS mark regardless of resolution. Instead, the frame rates fall steadily with each resolution increase, confirming that the Arc B390's rendering throughput is the primary constraint.

The 4K results are particularly telling. Even at Low settings, the combo only manages 31 FPS, while Medium settings produce 21 FPS with a minimum of 18 FPS and a maximum of 24 FPS. These numbers indicate that 4K gaming is not viable with this configuration, and even 1440p requires settings reductions to achieve playable frame rates. The 1080p results, by contrast, show that Low settings can deliver a smooth experience, with Medium settings at 51 FPS and High settings at 43 FPS representing reasonable compromises.

FAQ

Q: What is the best settings configuration for this combo in Rust?

A: Based on the measured data, 1080p with Low settings delivers the highest average frame rate at 76 FPS. For a balance of quality and performance, 1080p Medium achieves 51 FPS, while 1080p High reaches 43 FPS. Higher resolutions or settings will result in sub-60 FPS performance.

Q: How does this combo compare to the Ryzen 5 5600G's CPU rivals?

A: The Ryzen 5 5600G has an average benchmark score of 21088, which is 0.1% higher than the Intel Core i3-1220P (21066), 0.1% lower than the Intel Core Ultra 7 256V (21112), 0.2% lower than the AMD Ryzen 5 7530U (21133), and 0.4% lower than the Intel Core Ultra 7 155U (21174). The CPU itself is competitive with these parts, but the GPU drags the overall combo down.

Q: Is the Intel Arc B390 comparable to any dedicated GPUs?

A: The Arc B390's nearest rivals in the benchmark database are all integrated or legacy mobile parts. It scores 1482 in 3DMark Steel Nomad DX12, which is 1.3% higher than the GeForce GT 520MX (1463), 1.5% higher than the GeForce 800M (1460), 2.5% higher than the GeForce GT 625 OEM (1446), and 2.7% higher than the GeForce GT 710 (1443). These are all parts from the entry-level segment of a much older era.

Q: What frame rates can I expect at 1440p with this combo?

A: At 1440p, the measured results show 53 FPS on Low settings, 35 FPS on Medium settings with a range of 30-41 FPS, 30 FPS on High settings, and 23 FPS on Ultra settings. None of these configurations reach 60 FPS, so 1440p gaming will require accepting lower frame rates.

Q: Does the CPU bottleneck the GPU in this configuration?

A: The data suggests the opposite — the GPU is the limiting factor. The CPU sits at the 74th percentile among all CPUs, while the GPU sits at the 9th percentile. The frame rate drops consistently as resolution increases, which indicates the GPU's rendering throughput is the constraint, not the CPU's processing capability.

Q: How many ray tracing cores does the Arc B390 have, and does it matter for Rust?

A: The Arc B390 has 12 ray tracing cores. However, given that the GPU's overall performance is limited — it ranks at the 9th percentile among all GPUs — these cores are unlikely to provide meaningful ray tracing performance in Rust. The measured frame rates at all settings and resolutions suggest the GPU is already struggling with standard rendering.

Measured FPS Breakdown

The measured frame rates for this combo in Rust span four resolutions and four settings tiers, providing a complete picture of performance.

At 1920x1080, the results are as follows: Low settings achieve 76 FPS on average. Medium settings achieve 51 FPS on average, with a minimum of 44 FPS and a maximum of 59 FPS. High settings achieve 43 FPS on average. Ultra settings achieve 33 FPS on average. The 1080p results show that only Low settings can deliver a consistently smooth experience above 60 FPS, while Medium settings hover near the threshold.

At 2560x1440, performance drops noticeably. Low settings achieve 53 FPS on average. Medium settings achieve 35 FPS on average, with a minimum of 30 FPS and a maximum of 41 FPS. High settings achieve 30 FPS on average. Ultra settings achieve 23 FPS on average. The 1440p results indicate that even Low settings cannot maintain 60 FPS, and Medium settings will experience dips into the low 30s.

At 3840x2160, the results are marginal. Low settings achieve 31 FPS on average. Medium settings achieve 21 FPS on average, with a minimum of 18 FPS and a maximum of 24 FPS. High settings achieve 18 FPS on average. Ultra settings achieve 13 FPS on average. The 4K results are below playable thresholds across all settings, with even the lowest settings producing less than a third of the frame rate needed for smooth gameplay.

The scaling pattern is consistent: each step from 1080p to 1440p to 4K reduces frame rates by roughly 30-40%, regardless of settings. This consistency reinforces the conclusion that the GPU is the primary constraint. The minimum and maximum frame rates recorded at Medium settings show some variance, but the ranges are tight — at 1080p the range is 44-59 FPS, at 1440p it is 30-41 FPS, and at 4K it is 18-24 FPS. This suggests relatively stable frame pacing, though at levels that are too low for competitive play at higher resolutions.

CPU Role

The AMD Ryzen 5 5600G is a 6-core, 12-thread processor based on the Zen 3 architecture, codenamed Cezanne, built on a 7 nm process from TSMC. It has a base clock of 3.90 GHz and a boost clock of 4.40 GHz, with a TDP of 65 W. The CPU features 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 16 MB of L3 cache. It supports DDR4 memory in a dual-channel configuration with a memory bandwidth of 51.2 GB/s. The CPU's launch MSRP was $259, and it uses the AMD Socket AM4 interface with PCIe Gen 3 (16 lanes for the CPU). It also includes integrated Radeon Vega 7 graphics, though this combo pairs it with the separate Arc B390.

In synthetic benchmarks, the Ryzen 5 5600G demonstrates solid performance. Its Cinebench R23 multicore score is 10551, with a single-core score of 1409. The Geekbench multicore score is 8428, and the single-core score is 1801. In PassMark, the multithread score is 19717, with a single-thread score of 3177. The CPU's 3DMark results show scaling from 872 in single-thread to 5455 at max threads, indicating good multi-threaded utilization. Its average benchmark score of 21088 places it at the 74th percentile among all CPUs, and its nearest rivals are all within 0.4% of its score — the Intel Core i3-1220P at 21066 (0.1% slower), the Intel Core Ultra 7 256V at 21112 (0.1% faster), the AMD Ryzen 5 7530U at 21133 (0.2% faster), and the Intel Core Ultra 7 155U at 21174 (0.4% faster).

In Rust, the CPU's role is to feed the GPU with draw calls and game logic. The measured frame rates suggest that the CPU is more than capable of this task at 1080p Low, where the combo reaches 76 FPS. If the CPU were the bottleneck, we would expect to see the frame rate plateau around that level regardless of resolution or settings. Instead, the frame rates decline steadily as resolution increases, which indicates that the GPU is saturated before the CPU reaches its limit.

The CPU's 6 cores and 12 threads are adequate for Rust's workload, which can utilize multiple threads for world simulation and entity updates. The boost clock of 4.40 GHz provides strong single-thread performance, which is important for games that rely heavily on a main thread. However, the overall combo performance is constrained by the Arc B390's low benchmark scores, and no amount of CPU headroom can compensate for the GPU's limited rendering throughput. The result is a system where the CPU is underutilized at higher resolutions because the GPU cannot keep up, while at 1080p Low, the CPU enables the GPU to reach its maximum output of 76 FPS.
