Roblox

Roblox with the AMD Ryzen 5 4600G and NVIDIA GeForce RTX 4070 SUPER produces extremely high frame rates across all tested settings, but the pattern of scaling between resolutions reveals a system that is heavily CPU-bound. The data indicates that this combination is more than capable of delivering a fluid experience, though the headroom available at lower resolutions is largely untapped due to the processor's limits.

Resolution Scaling

The measured FPS data shows a dramatic shift in performance as resolution increases, which is the classic signature of a CPU bottleneck at lower resolutions. At 1080p with High settings, the combo achieves an average of 449.8 FPS. Moving to 1440p at the same settings, the average drops to 302.4 FPS, a reduction of approximately 33%. At 4K, the average falls further to 168.3 FPS, which is another 44% drop from the 1440p figure.

However, the most telling comparison is between the Low and Ultra presets at each resolution. At 1080p Low, the system hits 559.8 FPS, while at 1080p Ultra it manages 362.5 FPS. The difference between these two is 197.3 FPS, which indicates that the GPU has significant headroom to render more frames when the visual load is light. Yet, at 4K, the gap between Low (210.4 FPS) and Ultra (137.1 FPS) is 73.3 FPS, showing that the GPU is becoming the limiting factor as pixel count rises.

This scaling pattern suggests that at 1080p, the Ryzen 5 4600G's single-thread performance is the primary constraint. The GPU is capable of producing far more frames than the CPU can feed it, especially on Low settings. At 4K, the situation reverses; the GPU's workload becomes heavy enough that its performance dictates the frame rate, though the CPU still keeps the average above 137 FPS even on Ultra. The data shows that the transition from 1080p to 1440p yields a larger relative performance hit than the transition from 1440p to 4K, which confirms that the CPU is holding back performance until the resolution is high enough to saturate the GPU.

Settings Recommendations

The measured rows provide a clear hierarchy of performance across presets, and the choice of settings depends heavily on the target resolution. For players using a 1080p display, the High preset at 449.8 FPS offers an excellent balance of visual quality and speed, while the Ultra preset at 362.5 FPS still provides a very high refresh rate experience. The Low preset at 559.8 FPS is only useful for competitive play where every frame matters, but the visual compromise is substantial.

At 1440p, the Medium preset delivers 342.2 FPS, which is only slightly lower than High at 302.4 FPS. This makes Medium the recommended setting for this resolution, as it provides a meaningful visual upgrade over Low (373.2 FPS) while staying well above the refresh rate of most high-end monitors. The Ultra preset at 241.6 FPS is still playable, but the performance cost of moving from Medium to Ultra is 100.6 FPS, which is a steep price for the visual gains.

For 4K gaming, the data suggests that High settings at 168.3 FPS is the sweet spot. The Medium preset at 192.7 FPS is also viable, but the difference between High and Ultra is 31.2 FPS, which is significant. The Low preset at 210.4 FPS is the only way to approach 200 FPS at this resolution, but the visual quality will be noticeably reduced. The benchmark results indicate that High settings at 4K is the best compromise for this combo, as it keeps the frame rate comfortably above 144 FPS while maintaining a reasonable level of graphical fidelity.

GPU Role

The NVIDIA GeForce RTX 4070 SUPER is a high-end graphics card based on the Ada Lovelace architecture, and its specifications suggest it has ample resources for Roblox. It features 7168 shading units, 224 texture mapping units, and 80 render output units, along with 56 ray tracing cores and 224 tensor cores. The memory configuration includes 12 GB of GDDR6X on a 192-bit bus, providing a bandwidth of 504.2 GB/s.

In terms of clock speeds, the GPU has a base clock of 1980 MHz and a boost clock of 2475 MHz. The memory operates at 1313 MHz, which translates to 21 Gbps effective. These figures are high, and the benchmark results show that the GPU is not the limiting factor in Roblox until the resolution reaches 4K. The passmark G3D score of 29995 places it in the 84th percentile of all GPUs, and its average benchmark score of 42576 is nearly identical to the NVIDIA RTX A6000, which has a deltaPct of -0.2%.

The data from the measured FPS rows shows that the GPU's performance scales as expected with resolution. At 1080p, the GPU is underutilized, which is why the frame rates are so high. At 4K, the GPU's compute and memory bandwidth become more relevant, and the frame rates drop to a level that still exceeds the requirements of most displays. The GPU's 12 GB of VRAM is more than sufficient for Roblox at any resolution, as the game's textures and geometry are not demanding enough to stress this amount of memory.

How This Combo Ranks

The combination of the Ryzen 5 4600G and the RTX 4070 SUPER ranks 344th out of 1800 tested combos in Roblox. This places it in the top 19.1% of all combinations, which is a strong result given the processor's modest specifications. The ranking reflects the fact that the GPU is powerful enough to push high frame rates, but the CPU's limitations prevent the combo from reaching the absolute top tier.

The CPU's percentile vs all CPUs is 75, and its average benchmark score of 17489 is nearly identical to its nearest rival, the AMD Ryzen 3 PRO 5355GE, which has a deltaPct of 0. The Intel Core i5-12450H is also close, with a deltaPct of 0.1%. This indicates that the 4600G is a solid mid-range processor, but it is not in the same class as the top CPUs that would be paired with the RTX 4070 SUPER in other combos. The combo's rank of 344 suggests that there are 343 other combinations that achieve higher frame rates, likely due to having a more powerful processor.

However, the rank is still impressive because the RTX 4070 SUPER is able to compensate for the CPU's weaknesses in Roblox. The game is not heavily multi-threaded, and the CPU's single-thread performance of 1919 in Cinebench R23 is adequate for the task. The combination of a strong GPU and a decent CPU results in a system that performs well above average, even if it does not reach the heights of the top-ranked combos.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, codenamed Renoir. It has a base clock of 3.70 GHz and a boost clock of 4.20 GHz, with a 65 W TDP. The CPU features 8 MB of shared L3 cache, and its memory support is dual-channel DDR4 with a bandwidth of 51.2 GB/s.

The benchmark data shows that the CPU's multi-threaded performance is respectable, with a Cinebench R23 multicore score of 13593 and a Passmark multithread score of 15992. Its single-thread performance, however, is more modest, with a Cinebench R23 single-core score of 1919 and a Passmark single-thread score of 2653. This single-thread performance is the key factor in Roblox, as the game tends to rely heavily on one or two cores.

The measured FPS results confirm this analysis. At 1080p Low, the system reaches 559.8 FPS, which is likely near the CPU's maximum frame generation limit. The fact that increasing the resolution to 4K only drops the Low preset to 210.4 FPS suggests that the CPU is still able to keep up at higher resolutions, but the gap between Low and High at 1080p (110 FPS) indicates that the CPU is the bottleneck. The CPU's 75th percentile ranking among all CPUs means it outperforms three-quarters of its peers, but in a game like Roblox, the single-thread performance is more important than the core count.

The CPU's integrated Radeon Vega 7 graphics are irrelevant in this configuration, as the discrete RTX 4070 SUPER handles all rendering. The processor's 12 threads provide enough parallelism for background tasks, but the game's performance is dictated by its ability to process game logic and draw calls quickly. The data shows that the 4600G is a capable partner for the RTX 4070 SUPER, but it does leave some performance on the table at lower resolutions.
