Roblox

Roblox, a sandbox title from 2006, behaves unusually in benchmarking because its visual workload scales dramatically with user-generated content. For the AMD Ryzen 5 4600G paired with the NVIDIA GeForce RTX 2070 SUPER, the measured frame rates show that the game is heavily CPU-bound at lower resolutions, while the GPU becomes more relevant as resolution increases. The data indicates that the "High" preset offers the most balanced experience, delivering 274 FPS at 1080p, 180.5 FPS at 1440p, and 102.5 FPS at 4K, which are all playable on high-refresh displays. Higher presets like "Ultra" impose a significant penalty—dropping 1080p performance to 220.7 FPS and 4K to 85.4 FPS—without a clear benefit for a game this dependent on simple geometry and user-generated scripts.

Settings Recommendations

The measured FPS table shows a clear hierarchy across all resolutions: "Low" is fastest, followed by "Medium," then "High," with "Ultra" being the slowest. At 1080p, the spread is substantial: "Low" hits 339.8 FPS, "Medium" 311.2 FPS, "High" 274 FPS, and "Ultra" 220.7 FPS. The gap between "High" and "Ultra" is 53.3 FPS, which represents a 19.5% performance loss for the highest preset. Given that Roblox's visual differences between "High" and "Ultra" are often subtle (mostly affecting shadow quality and draw distance), the "High" preset is the recommended default. It maintains a frame rate above 220 FPS at 1080p, which is well beyond the refresh rate of most monitors, while providing better visual fidelity than "Low" or "Medium".

At 1440p, the same pattern holds: "High" delivers 180.5 FPS, which is still high enough for a 144Hz display. "Ultra" at 144.5 FPS is close to that threshold, but the 36 FPS difference between "High" and "Ultra" (a 20% drop) makes "High" the safer choice. At 4K, "High" produces 102.5 FPS, which is suitable for a 100Hz or 120Hz display, while "Ultra" falls to 85.4 FPS, which may still be acceptable but leaves less headroom for frame-time spikes. The data suggests that "High" is the sweet spot because it preserves most visual quality while avoiding the disproportionate cost of "Ultra". For competitive play, "Medium" at 311.2 FPS (1080p) or 208.5 FPS (1440p) offers a meaningful boost over "High" with minimal visual degradation, making it a viable alternative for esports-style scenarios within Roblox.

CPU Role

The Ryzen 5 4600G is a 6-core, 12-thread processor from the 4000 series, based on Zen 2 architecture on a 7 nm process. Its base clock is 3.70 GHz with a boost clock of 4.20 GHz. In synthetic benchmarks, it scores 13593 in Cinebench R23 multi-core and 1919 in single-core, placing it at the 75th percentile among all CPUs. Its nearest rival, the AMD Ryzen 3 PRO 5355GE, has an average score of 17482 (0% delta), while the Intel Core i5-12450H scores 17475 (0.1% delta), indicating that the 4600G is slightly above average for its class.

In Roblox, the CPU's role is dominant at lower resolutions. At 1080p, the difference between "Low" (339.8 FPS) and "Ultra" (220.7 FPS) is 119.1 FPS, which is a 54% spread. This wide gap indicates that the CPU is the primary bottleneck, as the GPU is not being fully utilized at such high frame rates. The 4600G's single-thread performance (1919 in Cinebench R23) is adequate for Roblox's physics and scripting, but the game's engine is not highly optimized for multi-threading. The 6-core/12-thread configuration helps with background tasks, but the benchmark results suggest that clock speed and single-core efficiency matter more. The boost clock of 4.20 GHz is respectable, yet the data shows that the CPU cannot sustain frame rates above 340 FPS even at "Low" settings, indicating a hard ceiling. Compared to the Intel Core i3-13100F (which has a -1% delta in average benchmark score), the 4600G performs similarly in CPU-bound scenarios, but its higher thread count (12 vs. 8) may help in games that use more threads. For Roblox, the CPU is the limiting factor at 1080p, but as resolution increases to 4K, the GPU takes over as the primary constraint.

GPU Role

The NVIDIA GeForce RTX 2070 SUPER is a Turing-architecture GPU with 2560 shading units, 160 texture mapping units, and 64 ROPs. It has 8 GB of GDDR6 memory on a 256-bit bus, providing 448.0 GB/s of bandwidth. Its base clock is 1605 MHz with a boost clock of 1770 MHz, and it achieves 9.062 TFLOPS of FP32 performance. In synthetic tests, it scores 18169 in Passmark G3D and 98316 in Geekbench OpenCL, placing it at the 65th percentile among all GPUs. Its nearest rival, the NVIDIA RTX A400, has an average score of 22307 (-0.5% delta), while the AMD Radeon RX 5700 scores 21670 (2.5% delta), showing that the RTX 2070 SUPER is competitive but not top-tier.

In Roblox, the GPU's role becomes more prominent at 4K. At 3840x2160, the frame rate drops from 127.7 FPS on "Low" to 85.4 FPS on "Ultra" — a 42.3 FPS difference (a 49.5% penalty). This drop is more severe than at 1080p, where the same settings change only costs 119.1 FPS (a 54% penalty but from a much higher base). The data shows that at 4K, the GPU is the limiting factor, as the 8 GB VRAM and 448.0 GB/s bandwidth are sufficient for Roblox's modest textures, but the raw compute power (9.062 TFLOPS) is taxed by the higher pixel count. The RTX 2070 SUPER's 64 ROPs and 113.3 GPixel/s pixel rate are adequate for fill-rate demands, but the game's draw calls and shader complexity at "Ultra" settings push the GPU harder. Notably, the difference between "High" (102.5 FPS) and "Medium" (113.4 FPS) at 4K is only 10.9 FPS, suggesting that the GPU handles "Medium" and "High" similarly, but "Ultra" triggers additional effects that cause a steep drop. This pattern indicates that Roblox's "Ultra" preset includes GPU-heavy features like dynamic lighting and higher-resolution shadows, which the RTX 2070 SUPER can only manage at 85.4 FPS at 4K.

Resolution Scaling

The measured FPS data shows a clear pattern of diminishing returns as resolution increases. At 1080p, "High" settings yield 274 FPS. Moving to 1440p, the same settings drop to 180.5 FPS — a 93.5 FPS decrease (34.1% reduction). Moving further to 4K, "High" settings yield 102.5 FPS — a 78 FPS decrease from 1440p (43.2% reduction) and a 171.5 FPS decrease from 1080p (62.6% reduction). This steep drop-off indicates that the system is heavily CPU-bound at 1080p, but the GPU becomes the limiting factor as resolution climbs.

This is confirmed by looking at the "Low" settings row: at 1080p, "Low" achieves 339.8 FPS, but at 4K it only reaches 127.7 FPS. The 4K figure is only 37.6% of the 1080p figure, which is a typical scaling curve for a GPU-bound workload. In contrast, the "Ultra" settings row shows a smaller absolute drop: from 220.7 FPS at 1080p to 85.4 FPS at 4K — a 135.3 FPS reduction (61.3% lower). This suggests that at "Ultra", both CPU and GPU are stressed, but the GPU's inability to handle the increased shading load at 4K is the primary constraint. The data indicates that the RTX 2070 SUPER's 8 GB of VRAM and 448.0 GB/s bandwidth are enough for Roblox's textures, but the 9.062 TFLOPS of compute power is insufficient to maintain high frame rates at 4K when settings are maxed out. For users targeting 1440p, the system is well-balanced, as "High" settings still deliver 180.5 FPS, which is above 144Hz. At 4K, the system requires "Medium" or "Low" settings to exceed 120 FPS, as only "Medium" (113.4 FPS) and "Low" (127.7 FPS) manage that.
