Roblox

The AMD Ryzen 7 5700G paired with the NVIDIA GeForce RTX 4070 SUPER delivers exceptionally high frame rates in Roblox across all tested configurations. At 1080p, the average FPS ranges from 367.5 on Ultra settings to 559.9 on Low, while at 1440p the range is 242.1 to 375, and at 4K it spans 135.4 to 214.7. This combination ranks 333rd out of 1800 tested combos for this game, placing it in the top percentile of systems.

Settings Recommendations

The measured data indicates that the High preset provides the most balanced experience across all resolutions. At 1080p, High delivers 449.6 FPS, which is 82.1 FPS lower than Low but 82.5 FPS higher than Ultra. The gap between Medium and High is 58.5 FPS at 1080p, making High the optimal choice for users who want visual fidelity without sacrificing significant performance. At 1440p, High produces 297.9 FPS, while Medium reaches 340.9 and Ultra drops to 242.1. The 1440p High result remains well above the refresh rate of most high-end monitors, and the visual improvements over Medium justify the 43 FPS difference. At 4K, High achieves 168.6 FPS, which is 24.1 FPS below Medium but 33.2 FPS above Ultra.

For competitive play where maximum frame rates matter, the Low preset at 1080p offers 559.9 FPS, which is 110.3 FPS higher than High. However, this comes at a visual cost that may not be necessary given that even Ultra at 1080p maintains 367.5 FPS. The data suggests that High is the sweet spot for most users, as it consistently provides frame rates that exceed the capabilities of typical displays. At 4K, Ultra drops to 135.4 FPS, which is still playable but represents a 33.2 FPS reduction from High; users with 4K displays should stick with High to maintain smoother motion. The Medium preset offers a middle ground, with 508.1 FPS at 1080p, 340.9 FPS at 1440p, and 192.7 FPS at 4K, but the incremental gain over High is minimal compared to the visual downgrade.

GPU Role

The NVIDIA GeForce RTX 4070 SUPER is the dominant component in this system for Roblox, as evidenced by the frame rate scaling across resolutions. The GPU features 12 GB of GDDR6X memory on a 192-bit bus, providing 504.2 GB/s of bandwidth. Its boost clock of 2475 MHz and base clock of 1980 MHz contribute to its 35.48 TFLOPS of FP32 performance. The GPU's 7168 shading units and 224 texture mapping units handle Roblox's relatively simple geometry with ease.

The benchmark data shows that the RTX 4070 SUPER is rarely the limiting factor in this game. At 1080p, the GPU's utilization is likely low, as the CPU becomes the bottleneck at such high frame rates. The difference between Low and Ultra at 1080p is 192.4 FPS, which indicates that the GPU has substantial headroom even at maximum settings. At 4K, the GPU begins to show its influence more clearly: the gap between Low and Ultra is 79.3 FPS, compared to 192.4 FPS at 1080p. This narrowing gap suggests that at higher resolutions, the GPU's rendering workload increases and it starts to become more relevant, though it still never drops below 135.4 FPS even at Ultra 4K.

The GPU's 84th percentile ranking among all GPUs, with an average benchmark score of 42576, places it slightly below the NVIDIA RTX A6000 (which has a deltaPct of -0.2) and just above the AMD Radeon RX 7650 GRE (deltaPct of -0.3). This performance class is more than sufficient for Roblox, where even the most demanding scenes do not stress the GPU's capabilities. The 12 GB VRAM is ample for Roblox's texture and asset requirements, and the memory bandwidth of 504.2 GB/s ensures no bandwidth-related stutters. The GPU's DirectX 12 Ultimate support and Vulkan 1.4 compatibility align well with Roblox's rendering needs.

CPU Role

The AMD Ryzen 7 5700G provides strong single-thread and multi-thread performance that complements the GPU well in Roblox. This CPU has 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.80 GHz and a boost clock of 4.60 GHz. Its 16 MB of L3 cache and 512 KB L2 cache per core help with game logic and physics calculations. The CPU's single-thread performance is critical for Roblox, as the game's engine typically relies heavily on one or two threads for core simulation tasks.

Benchmark results show the 5700G achieves a 3dmark_single_thread score of 899 and a passmark_single_thread score of 3283. In multi-threaded workloads, it scores 6629 in 3dmark_16_threads and 20755 in cinebench_r23_multicore. The CPU's percentile ranking of 83 among all CPUs, with an average benchmark score of 25626, places it nearly even with the AMD Ryzen 7 6800U (deltaPct of -0.3) and slightly ahead of the Intel Xeon D-2752TER (deltaPct of 0.4).

At 1080p resolution, the CPU's role becomes more apparent. The frame rates at this resolution are extremely high—559.9 FPS on Low—which indicates that the CPU is capable of feeding the GPU with enough draw calls to maintain such performance. The diminishing returns from 1080p to 1440p to 4K show that the CPU is less of a constraint as resolution increases. At 1080p, the difference between Low and Ultra is 192.4 FPS, but at 4K it's only 79.3 FPS. This pattern suggests that at lower resolutions, the CPU is the primary limiter, while at 4K, the GPU's workload becomes more balanced with the CPU's capabilities. The 5700G's 16 threads ensure that even if Roblox spawns background threads for asset streaming or network processing, there is ample headroom. The 65W TDP and 7 nm process node from TSMC make it a power-efficient choice that doesn't generate excessive heat during extended gaming sessions.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals important information about which component limits performance in Roblox. At High settings, the system delivers 449.6 FPS at 1080p, 297.9 FPS at 1440p, and 168.6 FPS at 4K. This represents a 33.7% drop in FPS when moving from 1080p to 1440p, and another 43.4% drop from 1440p to 4K. The total reduction from 1080p to 4K is 62.5%, which is less than the theoretical 4x pixel count increase (from 2.1 million pixels at 1080p to 8.3 million at 4K) would suggest if the GPU were fully saturated.

This pattern indicates that at 1080p, the CPU is the primary bottleneck. The 5700G's single-thread performance of 899 in 3dmark and 3283 in passmark single-thread limits how many frames the CPU can prepare for the GPU. As resolution increases, the GPU's rendering workload grows, allowing it to become more utilized and reducing the CPU's relative impact. The difference between Low and Ultra settings across resolutions supports this analysis: at 1080p, the spread from Low to Ultra is 192.4 FPS (559.9 to 367.5), while at 4K it's only 79.3 FPS (214.7 to 135.4).

The 4K results show the system is still heavily GPU-bound at the highest settings, with Ultra delivering 135.4 FPS. The GPU's 504.2 GB/s memory bandwidth and 12 GB of GDDR6X VRAM are sufficient for Roblox's asset streaming at 4K, and the 2475 MHz boost clock ensures consistent performance. The scaling data suggests that users with high refresh rate 1080p or 1440p monitors will benefit most from this combination, as the CPU keeps frame rates well above 240 FPS at these resolutions. At 4K, the system still provides excellent performance, but the GPU becomes the more significant factor, as evidenced by the narrower FPS range between settings presets at this resolution.
