Roblox

The AMD Ryzen 9 7900X and NVIDIA GeForce RTX 4080 SUPER combination delivers exceptionally high frame rates in Roblox, a Sandbox title released on 2006-08-31. The measured data shows that this pairing is capable of pushing frame rates well beyond the refresh rates of most displays across all tested settings and resolutions. The benchmark results indicate a system that is overwhelmingly powerful for this particular game, with performance characteristics that shift from GPU-bound at higher resolutions to CPU-bound at lower ones.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor from the 7000 series, built on the Zen 4 architecture (codenamed Raphael) using a 5 nm process at TSMC. It operates with a base clock of 4.70 GHz and a boost clock of 5.60 GHz, with a TDP of 170 W on the AMD Socket AM5 platform. The processor features a substantial cache hierarchy, including 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3 cache. Memory support includes DDR5 with dual-channel configuration and a bandwidth of 83.2 GB/s, alongside PCIe Gen 5 with 24 lanes available from the CPU.

In the context of Roblox, the CPU's role is particularly pronounced at lower resolutions. The data shows that at 1920x1080 with Low settings, the system achieves 641.7 FPS, which is the highest frame rate recorded in the entire dataset. This suggests that the Ryzen 9 7900X's single-thread performance is a critical factor, as Roblox tends to rely heavily on a limited number of threads for its physics and game logic. The processor's single-thread benchmark scores are noteworthy, with a 3dmark_single_thread score of 1093 and a passmark_single_thread score of 4238. These results indicate robust per-core capability, which is essential for maintaining high frame rates when the GPU is not the bottleneck.

The multi-threaded performance of the 7900X is equally strong, with a cinebench_r23_multicore score of 43695 and a passmark_multithread score of 51406. However, the benchmark results suggest that Roblox does not fully utilize this multi-threading headroom. At 2560x1440 with Ultra settings, the frame rate drops to 278.6 FPS, and at 3840x2160 with Ultra settings, it falls further to 159.9 FPS. This scaling pattern indicates that the CPU is not the limiting factor at higher resolutions; instead, the GPU takes over as the primary constraint. The CPU's 93.0 percentile ranking against all CPUs, with an average benchmark score of 50556, places it in the top tier of processors, and its nearest rivals include the Intel Core Ultra 5 235 with a deltaPct of -0.1, the AMD Ryzen 9 5900XT at -0.4, and the Intel Core i7-13850HX at -0.5. This tight grouping suggests that the 7900X delivers performance on par with its immediate competitors.

The GPU's clocks are set at 2295 MHz base and 2550 MHz boost, with memory running at 1438 MHz (23 Gbps effective). The card includes 10240 shading units, 320 TMUs, and 112 ROPs, along with 80 RT cores and 320 tensor cores. Its compute capabilities are substantial, with an FP32 performance of 52.22 TFLOPS and a texture rate of 816.0 GTexel/s.

In Roblox, the GPU's role becomes increasingly dominant as resolution and settings are raised. The measured frame rates show a clear progression: at 1920x1080 with Low settings, the system hits 641.7 FPS, which drops to 417.0 FPS at Ultra settings. Moving to 2560x1440, the frame rates range from 427.7 FPS at Low to 278.6 FPS at Ultra. At 3840x2160, the range is 244.0 FPS at Low down to 159.9 FPS at Ultra. This pattern demonstrates that the RTX 4080 SUPER is well-equipped to handle Roblox's visual demands, even at 4K resolution. The GPU's 16 GB of VRAM is more than sufficient for this game, as Roblox does not typically require large memory allocations, and the 88.0 percentile ranking against all GPUs confirms its high-end status.

The GPU's benchmark scores are equally impressive, with a passmark_g3d score of 34245 and a geekbench_opencl score of 246994. Its nearest rivals include the AMD Radeon RX 6900 XT with a deltaPct of 0.2, the AMD Radeon Pro W6600M at 0.4, the AMD Radeon RX 7700S at 2.1, and the NVIDIA GeForce RTX 5070 Ti at 2.9. These deltas are relatively small, indicating that the RTX 4080 SUPER sits in a competitive performance bracket. The GPU's average benchmark score of 53610 places it just ahead of these rivals, reinforcing its position as a top-tier solution for high-refresh-rate gaming.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear scaling pattern across resolutions, which provides insight into the system's bottleneck behavior. At 1920x1080 with Low settings, the system achieves 641.7 FPS. When moving to 2560x1440 at the same settings, the frame rate drops to 427.7 FPS, a decrease of approximately 33%. Further scaling to 3840x2160 at Low settings yields 244.0 FPS, which is a 62% reduction from the 1080p figure. This substantial drop indicates that the GPU is becoming the limiting factor at higher resolutions, as the rendering workload increases significantly with pixel count.

The pattern is consistent across all settings. At High settings, the frame rates are 516.9 FPS at 1080p, 344.5 FPS at 1440p, and 192.5 FPS at 4K. At Ultra settings, the figures are 417.0 FPS, 278.6 FPS, and 159.9 FPS, respectively. The relative drops between resolutions are more pronounced at lower settings, suggesting that the CPU has more headroom at 1080p but is eventually overwhelmed as the GPU demands more data. At 1080p Low, the system is likely CPU-bound, as the GPU has ample capacity to render frames quickly, but the CPU's single-thread performance limits the maximum frame rate. As resolution increases, the GPU's workload grows, and the bottleneck shifts to the graphics card.

This analysis is supported by the fact that the frame rates at 4K Ultra (159.9 FPS) are still exceptionally high, indicating that even at the most demanding settings, the RTX 4080 SUPER has sufficient power to maintain smooth gameplay. The data suggests that for Roblox, the RTX 4080 SUPER is the primary limiting component at 1440p and above, while the Ryzen 9 7900X becomes the constraint at 1080p. This is a typical pattern for high-end systems in less demanding titles, where the CPU's single-thread performance is the final arbiter of peak frame rates.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of the system's performance across all tested configurations. At 1920x1080, the system delivers an average of 641.7 FPS with Low settings, 581.6 FPS with Medium settings, 516.9 FPS with High settings, and 417.0 FPS with Ultra settings. The performance gap between Low and Ultra is approximately 35%, which is a modest reduction given the visual quality improvements. This indicates that the CPU is a significant factor at this resolution, as the GPU has enough headroom to render frames quickly regardless of settings.

At 2560x1440, the frame rates are 427.7 FPS for Low, 386.5 FPS for Medium, 344.5 FPS for High, and 278.6 FPS for Ultra. The drop from Low to Ultra is roughly 35%, similar to the 1080p scaling, but the absolute values are lower. This suggests that the GPU is beginning to take a more prominent role, though the CPU still contributes to the overall performance. The transition from 1080p to 1440p results in a 33% decrease at Low settings, which aligns with the increased pixel count.

At 3840x2160, the frame rates are 244.0 FPS for Low, 219.6 FPS for Medium, 192.5 FPS for High, and 159.9 FPS for Ultra. The performance degradation from Low to Ultra is 34%, consistent with the other resolutions. However, the absolute values at 4K are significantly lower, with the Ultra setting dipping below 160 FPS. This clearly indicates that the GPU is the limiting component at this resolution, as the rendering workload becomes substantial. The data shows that the system maintains playable frame rates even at 4K Ultra, which reflects the RTX 4080 SUPER's capabilities.
