Roblox

Roblox is a sandbox title that behaves unlike most modern shooters or AAA releases, and the measured data for the AMD Ryzen 7 7700X and NVIDIA GeForce RTX 4070 SUPER combination reflects that unusual profile. The benchmark results show a system that is overwhelmingly capable of pushing frame rates far beyond display refresh rates at every tested setting, with the performance ceiling determined by the CPU at lower resolutions and by the GPU only at the most demanding 4K Ultra preset.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a distinct two-phase behavior. At 1920x1080, the average frame rate across all settings is astronomically high, ranging from 366.9 FPS on Ultra to 563.2 FPS on Low. Moving to 2560x1440 yields a predictable but modest drop: the Low preset falls from 563.2 FPS to 374.9 FPS, a 33% reduction, while the Ultra preset drops from 366.9 FPS to 242.5 FPS, a 34% reduction. This near-uniform scaling across settings at these resolutions indicates that the rendering pipeline is not the primary constraint; instead, the CPU is working near its limit.

The transition to 3840x2160 tells a different story. At 4K, the Low preset still manages 214 FPS, but the gap between settings narrows dramatically. The High preset produces 170.1 FPS, Medium delivers 194.2 FPS, and Ultra falls to 135.8 FPS. The scaling from 1440p to 4K is steeper than the step from 1080p to 1440p: Low drops by 43%, High by 43%, and Ultra by 44%. This consistent percentage drop, regardless of the preset, suggests that pixel throughput is becoming the limiting factor. The RTX 4070 SUPER, with its 12 GB of GDDR6X memory and 504.2 GB/s bandwidth, is being tasked with significantly more work at 4K, and the frame rate now responds more directly to resolution.

The data shows that at 1080p and 1440p, the CPU is the bottleneck, as evidenced by the fact that raising settings from Low to Ultra only reduces frame rates by 35% at 1080p (563.2 to 366.9 FPS) and 35% at 1440p (374.9 to 242.5 FPS). At 4K, the penalty for moving from Low to Ultra is 37% (214 to 135.8 FPS), but the absolute frame rates are low enough that the GPU is clearly the dominant factor. The key takeaway: this combination is overkill for Roblox at any resolution below 4K, and even at 4K Ultra, it still delivers 135.8 FPS, which is far beyond the needs of most displays.

CPU Role

The AMD Ryzen 7 7700X is a Zen 4 part built on a 5 nm process, featuring 8 cores and 16 threads. Its base clock of 4.50 GHz and boost clock of 5.40 GHz are high for a desktop processor, and the 32 MB shared L3 cache helps feed the cores efficiently. In synthetic benchmarks, this CPU scores 30325 in Cinebench R23 multicore and 4281 in single-core, placing it in the 89th percentile of all CPUs tested. Its nearest rivals, such as the Intel Core i5-13500, score 34175 (a 0.4% delta), and the Intel Core i7-12800HX scores 34136 (a 0.5% delta). The 7700X trails the Intel Core Ultra 7 165H by 0.8% and the AMD EPYC 4244P by 0.8%, showing it sits right in the middle of a tight pack of high-end processors.

For Roblox, the CPU role is paramount. The game’s physics and world logic are largely single-threaded, which is why the 7700X’s single-core performance is so important. The measured FPS at 1080p Low (563.2 FPS) is a direct reflection of the CPU’s ability to process game logic at extremely high speed. The 3DMark single-thread score of 1090 and Geekbench single-core score of 2985 corroborate this strength. Even at 4K Ultra, where the GPU is the bottleneck, the CPU still needs to keep up with a 135.8 FPS target, which the 7700X does without breaking a sweat.

The data suggests that this CPU is not the limiting factor in any of the tested configurations. The fact that frame rates at 1080p are nearly double those at 4K, irrespective of settings, points to the GPU taking over as the primary constraint only at higher resolutions. The 7700X’s 8 cores and 16 threads are more than sufficient for Roblox’s sandbox nature, and the 3DMark 16-thread score of 8859 indicates that even if the game were to scale to more threads, the CPU has headroom. In essence, the CPU is the engine that allows the GPU to stretch its legs at lower resolutions, and it does so with ample margin.

A: At 2560x1440 Medium, the average FPS is 339.9. At 3840x2160 Medium, it is 194.2. This is a 43% drop, showing a substantial penalty for the higher resolution but still leaving the system with a very high frame rate.

Measured FPS Breakdown

The measured data provides a complete picture of performance across all three resolutions and four quality presets. At 1920x1080, the system delivers exceptional frame rates: Low settings produce 563.2 FPS, Medium yields 506.6 FPS, High reaches 449.2 FPS, and Ultra drops to 366.9 FPS. The spread between Low and Ultra is 196.3 FPS, indicating that even the most demanding preset at this resolution is far from stressing the GPU.

At 2560x1440, the numbers scale down proportionally. Low settings run at 374.9 FPS, Medium at 339.9 FPS, High at 298.1 FPS, and Ultra at 242.5 FPS. The drop from High to Ultra is 55.6 FPS, which is consistent with the increased pixel count. The system remains well above 240 FPS even at the highest preset, making this resolution ideal for high-refresh-rate gaming.

At 3840x2160, the GPU begins to feel the load. Low settings achieve 214 FPS, Medium produces 194.2 FPS, High dips to 170.1 FPS, and Ultra falls to 135.8 FPS. The difference between Low and Ultra at 4K is 78.2 FPS, which is larger in absolute terms than at lower resolutions, confirming that the GPU is now the primary bottleneck. Notably, the gap between Medium and High at 4K is 24.1 FPS, while the gap between High and Ultra is 34.3 FPS, suggesting that the Ultra preset imposes a significant additional shader and texture load.

Across all configurations, the system never drops below 135.8 FPS, which means that for Roblox, this hardware combination is effectively overkill. The lowest recorded frame rate is at 4K Ultra, and it is still more than double the standard 60 FPS target.

GPU Role

The NVIDIA GeForce RTX 4070 SUPER is an Ada Lovelace part built on a 5 nm process, featuring 7168 shading units, 224 texture mapping units, and 80 raster output units. Its boost clock of 2475 MHz and base clock of 1980 MHz, combined with 12 GB of GDDR6X memory on a 192-bit bus, deliver a bandwidth of 504.2 GB/s. The GPU’s average benchmark score of 42576 places it in the 84th percentile of all GPUs, with its nearest rival being the NVIDIA RTX A6000 at 42653 (a 0.2% delta) and the AMD Radeon RX 7650 GRE at 42723 (a 0.3% delta). It is 1.4% faster than the AMD Radeon Pro 580X and 1.6% faster than the NVIDIA Tesla M40.

In Roblox, the GPU’s role becomes evident only at 4K. At 1080p and 1440p, the RTX 4070 SUPER is so far ahead of the CPU that it never reaches full utilization. The data shows that at 1080p Low, the GPU is producing 563.2 FPS, which is a clear sign that the CPU is the limiting factor. At 4K Ultra, the GPU’s pixel rate of 198.0 GPixel/s and texture rate of 554.4 GTexel/s are being exercised more fully, resulting in 135.8 FPS. The 12 GB of VRAM is more than sufficient for Roblox’s textures, even at 4K Ultra, and the 35.48 TFLOPS of FP32 compute power ensures that any shader complexity is handled with ease.

The transition from 1440p to 4K shows a steeper performance drop than the step from 1080p to 1440p, which is consistent with the GPU becoming the bottleneck. For instance, at High settings, 1440p yields 298.1 FPS while 4K yields 170.1 FPS, a 43% reduction. This is a clear indicator that the GPU is now processing significantly more fragments and textures. The RTX 4070 SUPER is not a workstation-class card like the RTX A6000, but its benchmark scores show it is competitive in the high-end consumer segment, and for Roblox, it provides more than enough performance to max out any display at any resolution. The GPU’s end-of-life production status and its successor, the GeForce 50 series, do not diminish its current capability in this title.
