Roblox

The AMD Ryzen 5 4600G paired with the Intel Arc B570 produces a highly capable Roblox system, with measured frame rates that remain fluid even at demanding 4K resolutions. The data shows a clear pattern where performance scales predictably with resolution and settings, but the relationship between the CPU and GPU shifts depending on the workload. This analysis breaks down the measured FPS data to explain where the bottleneck lies, the role of each component, and which settings offer the best experience.

Resolution Scaling

The measured FPS data reveals a distinct scaling pattern as resolution increases from 1920x1080 to 3840x2160. At 1080p with Low settings, the system achieves 262 FPS, which drops to 175 FPS at 1440p and further down to 99 FPS at 4K. This represents a 62% reduction in frame rate from 1080p to 4K at Low settings, indicating that the GPU is becoming progressively more stressed as pixel count increases. The scaling is not linear; the jump from 1080p to 1440p costs 87 FPS, while the jump from 1440p to 4K costs 76 FPS, showing that the GPU's rendering load grows faster than the resolution increase alone would suggest.

At Ultra settings, the pattern is similar but with lower absolute numbers. The system delivers 171 FPS at 1080p, 114 FPS at 1440p, and 65 FPS at 4K. The percentage drop from 1080p to 4K at Ultra is 62%, matching the Low settings' relative decline. This consistency across settings suggests that the scaling behavior is primarily driven by resolution, not by the complexity of the graphics preset. The fact that 4K Ultra still maintains 65 FPS indicates the Intel Arc B570 has enough headroom to handle this game's demands even at the highest resolution tested.

The Medium settings row provides additional insight, as it includes minimum and maximum frame rate data. At 4K Medium, the average is 90 FPS with a minimum of 77 FPS and a maximum of 104 FPS. This range of 27 FPS shows some variance, but the minimum staying above 60 FPS means the experience remains smooth. At 1440p Medium, the average rises to 159 FPS with a minimum of 135 FPS and maximum of 183 FPS. At 1080p Medium, the average reaches 239 FPS with a minimum of 203 FPS and maximum of 275 FPS. The minimum frame rates at each resolution stay remarkably close to the averages, suggesting that frame pacing is consistent and that neither the CPU nor GPU is causing severe stutters.

The resolution scaling data points toward the GPU being the primary limiting factor at higher resolutions. The frame rate drops of roughly 38% when moving from 1080p to 1440p, and another 43% when moving from 1440p to 4K, align with the increasing pixel count that the Arc B570 must process. At 1080p, however, the very high frame rates above 200 FPS suggest that the CPU might be reaching its limits, as the Ryzen 5 4600G's six cores and 12 threads can only feed the GPU so quickly. The fact that 1080p Low achieves 262 FPS but 1080p Ultra only reaches 171 FPS indicates that the GPU is still doing significant work even at lower resolutions, but the CPU's single-thread performance becomes more relevant at the highest frame rates.

GPU Role

The Intel Arc B570 brings substantial graphics capabilities to this pairing, with 10 GB of GDDR6 memory on a 160-bit bus providing 380.0 GB/s of bandwidth. This memory configuration is more than sufficient for Roblox's typical asset sizes, and the measured frame rates confirm that VRAM capacity does not become a constraint at any resolution or settings combination tested. The GPU's 2304 shading units, 144 texture mapping units, and 80 render output units work together to deliver the pixel throughput needed for the frame rates observed.

The Arc B570 operates at a consistent 2500 MHz for both base and boost clocks, which simplifies performance prediction. This fixed clock speed means the GPU does not experience boost variance that could cause frame rate fluctuations. The 11.52 TFLOPS of FP32 compute power provides ample raw performance for a game like Roblox, which relies more on geometry and draw calls than on heavy modern shading effects. The GPU's 18 ray tracing cores are present but likely underutilized in this title, as the measured data does not show any settings that would specifically stress ray tracing workloads.

The GPU's benchmark scores place it in a competitive position. Its PassMark G3D score of 14195 and average benchmark score of 20556 rank it at the 65th percentile among all GPUs. The nearest rivals show tight competition: the NVIDIA GeForce RTX 3070 Mobile scores 20534 with a delta of 0.1%, and the Intel Arc A750 scores 20582 with a delta of -0.1%. This means the Arc B570 is essentially performance-equivalent to these cards in synthetic benchmarks, and the measured Roblox frame rates likely reflect this level of capability. The GPU's PassMark DirectX 11 score of 118 and DirectX 12 score of 72 indicate strong API support, which matters for Roblox's rendering pipeline.

At 4K Ultra, the GPU is clearly the limiting factor, as the frame rate drops to 65 FPS. This is below the 80 FPS achieved at 4K High, showing that the Ultra preset's additional effects cost 15 FPS. The GPU's 200.0 GPixel/s pixel rate and 360.0 GTexel/s texture rate provide the theoretical foundation for these results. The 150 W TDP and 450 W suggested PSU indicate the card has reasonable power headroom, though power consumption is not directly measured in the FPS data.

CPU Role

The AMD Ryzen 5 4600G provides six cores and 12 threads based on the Zen 2 architecture, with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. This processor belongs to the 4000 series and uses the Renoir codename, built on a 7 nm process. The CPU's 8 MB of shared L3 cache and 512 KB of L2 cache per core provide adequate data locality for game workloads, though Roblox is not typically cache-sensitive. The dual-channel DDR4 memory support with 51.2 GB/s bandwidth ensures the CPU can feed data to the GPU without creating a memory bottleneck.

The CPU's single-thread performance is particularly relevant for Roblox, which often relies on a primary game thread. The Cinebench R23 single-core score of 1919 and Geekbench single-core score of 1460 indicate solid performance, but the PassMark single-thread score of 2653 reveals the processor's capabilities. The nearest CPU rivals show the Ryzen 5 4600G sitting in a tight cluster: the AMD Ryzen 3 PRO 5355GE scores 17482 with a 0.1% delta, and the Intel Core i3-14100T scores 17648 with a -0.8% delta. This means the 4600G performs nearly identically to these alternatives in synthetic benchmarks, with the 4600G's average benchmark score of 17507 placing it at the 71st percentile of all CPUs.

Multi-threaded performance is less critical for Roblox but still contributes to overall system responsiveness. The Cinebench R23 multi-core score of 13593 and PassMark multi-thread score of 15992 show that the six cores can handle background tasks while the game runs. The CPU's 3DMark scores, including 4889 for max threads and 726 for single thread, provide additional context for its gaming capabilities. The 65 W TDP keeps thermals manageable, allowing the boost clock to be sustained during extended gaming sessions.

The CPU's role in the measured FPS becomes evident when examining the 1080p results. At 1080p Low, the system achieves 262 FPS, which approaches the ceiling of what most displays can show. This high frame rate suggests the CPU can feed the GPU quickly enough at this resolution, but the gap between 1080p Low (262 FPS) and 1080p Ultra (171 FPS) shows that the GPU still has work to do even at lower resolutions. The fact that 1080p Medium reaches 239 FPS while 1440p Medium drops to 159 FPS indicates that the CPU is not the limiting factor at 1440p, as the GPU's workload increases with resolution.

Settings Recommendations

The measured FPS data suggests that the Medium preset offers the best balance between visual quality and performance across all resolutions. At 1080p Medium, the system achieves 239 FPS with a minimum of 203 FPS, which is well above any display's refresh rate capabilities and leaves headroom for frame time spikes. The Medium preset at 1440p delivers 159 FPS average with a 135 FPS minimum, ensuring smooth gameplay even during complex scenes. At 4K Medium, the average drops to 90 FPS with a minimum of 77 FPS, which remains comfortably above the 60 FPS playability threshold.

The High preset is a viable alternative at 1080p and 1440p, with averages of 211 FPS and 141 FPS respectively. However, at 4K High the average falls to 80 FPS, which is 10 FPS lower than Medium at the same resolution. The Ultra preset provides the highest visual fidelity but at a significant performance cost: at 4K Ultra the average is 65 FPS, and even at 1080p Ultra the average drops to 171 FPS, which is 68 FPS lower than Medium at the same resolution.

For players prioritizing frame rate smoothness, the Low preset provides the highest averages at every resolution, with 262 FPS at 1080p, 175 FPS at 1440p, and 99 FPS at 4K. However, the visual quality reduction may not be worth the performance gain, especially at 1440p and 4K where Medium already provides above-90 FPS averages. The data indicates that Medium is the sweet spot: it offers higher minimum frame rates than other presets at 4K (77 FPS versus no minimum data for High or Ultra), suggesting better frame pacing and reduced risk of stutters.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates across all settings. The Low preset averages 262 FPS, followed by Medium at 239 FPS with a minimum of 203 FPS and maximum of 275 FPS. High averages 211 FPS, and Ultra averages 171 FPS. The spread from Low to Ultra is 91 FPS, showing that settings have a substantial impact at this resolution where the GPU has relatively less pixel work to do.

Moving to 2560x1440, the frame rates decrease but remain high. Low averages 175 FPS, Medium averages 159 FPS with a minimum of 135 FPS and maximum of 183 FPS, High averages 141 FPS, and Ultra averages 114 FPS. The gap between Low and Ultra narrows to 61 FPS at this resolution, indicating that the GPU's workload is becoming more uniform across settings as pixel count increases.

At 3840x2160, the frame rates drop significantly. Low averages 99 FPS, Medium averages 90 FPS with a minimum of 77 FPS and maximum of 104 FPS, High averages 80 FPS, and Ultra averages 65 FPS. The difference between Low and Ultra is 34 FPS, the smallest gap across all resolutions, which confirms that the GPU is the dominant factor at 4K regardless of settings. The Medium preset's minimum of 77 FPS at 4K is particularly notable, as it ensures the frame rate never drops below the 60 FPS threshold even during the most demanding scenes.

How This Combo Ranks

The combination of the AMD Ryzen 5 4600G and Intel Arc B570 ranks 2405 out of 3010 tested combos in Roblox, placing it in the lower-middle portion of the database. This ranking of 2405 with 3010 total combos means the system outperforms approximately 20% of tested configurations but falls behind the majority. While the measured frame rates are high in absolute terms, the ranking indicates that many other CPU-GPU pairings deliver even higher performance in this specific game.

The component-level rankings provide context for this combo's position. The CPU sits at the 71st percentile among all processors, while the GPU sits at the 65th percentile among all graphics cards. The combo's rank of 2405 out of 3010 suggests that the pairing does not achieve the same relative performance as its individual components might indicate. This could be due to the CPU's Zen 2 architecture not being optimal for Roblox's specific workload, or the GPU's driver overhead affecting performance in this title.

The nearest rivals for each component help explain the combo's standing.
