# Resolution Scaling

The measured FPS data for Roblox with the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 5070 reveals a clear pattern of performance scaling across the three tested resolutions. At 1080p with Low settings, the combo delivers 541 FPS average. Moving to 1440p Low drops that to 366.1 FPS, a reduction of roughly 32%. At 4K Low, the average falls to 205.2 FPS, which represents a 62% decrease from the 1080p baseline. This steep drop-off as resolution increases indicates that the rendering workload scales heavily with pixel count.

The same trend holds across all settings presets. For High settings, the progression is 437.5 FPS at 1080p, 290 FPS at 1440p, and 168 FPS at 4K. Medium settings show 495.2 FPS at 1080p, 331.6 FPS at 1440p, and 184.4 FPS at 4K. Ultra settings produce 356.7 FPS at 1080p, 236.3 FPS at 1440p, and 132.5 FPS at 4K. The consistent pattern—roughly a 40% drop from 1080p to 1440p, followed by another 40% drop from 1440p to 4K—suggests the GPU is the limiting factor at higher resolutions.

At 1080p, the frame rates are extraordinarily high, exceeding 350 FPS even at Ultra settings. This indicates the CPU and GPU combination has ample headroom at lower pixel counts, and the workload is likely more balanced between processor and graphics card. The fact that 1080p Low reaches 541 FPS while 4K Low only reaches 205.2 FPS demonstrates that the RTX 5070's rendering pipeline becomes progressively more saturated as pixel output increases. Roblox, being a sandbox title with relatively modest graphical demands compared to AAA shooters, still shows measurable scaling behavior that follows expected GPU-bound patterns at higher resolutions.

GPU Role

The NVIDIA GeForce RTX 5070 plays a central role in determining Roblox performance, particularly at higher resolutions. The GPU's specifications include a boost clock of 2512 MHz, 6144 shading units, 192 texture mapping units, and 80 raster output units. Memory configuration consists of 12 GB of GDDR7 on a 192-bit bus, providing 672.0 GB/s of bandwidth. These specifications translate to a pixel rate of 201.0 GPixel/s and a texture rate of 482.3 GTexel/s. The FP32 compute throughput is rated at 30.87 TFLOPS.

The benchmark results show the GPU's average score is 41687, placing it in the 83rd percentile among all GPUs. Its nearest rivals include the AMD Radeon Pro 5300 with an average score of 41610 (0.2% higher), the NVIDIA GeForce RTX 3090 at 41441 (0.6% lower), and the NVIDIA Tesla M40 at 41897 (0.5% lower). This places the RTX 5070 in a tight competitive band, though the measured Roblox performance suggests the card handles this specific workload effectively.

At 4K Ultra, the RTX 5070 produces 132.5 FPS, which indicates the GPU is managing the increased pixel workload without becoming a bottleneck that forces frame rates below playable levels. The memory bandwidth of 672.0 GB/s appears well-suited for Roblox's texture and geometry requirements. The GPU's 48 ray tracing cores and 192 tensor cores are present, though Roblox's rendering pipeline may not fully utilize these specialized units. The 250 W TDP and dual-slot design suggest adequate power delivery for sustained performance, and the PCIe 5.0 x16 interface provides ample bandwidth for data transfer from the CPU.

Compared to the CPU's 93rd percentile ranking among all processors, the GPU's 83rd percentile ranking indicates the graphics card is relatively less dominant in this pairing. However, the measured frame rates demonstrate that the RTX 5070 is more than capable of driving Roblox at high refresh rates even at 1440p, where all settings presets exceed 236 FPS.

Settings Recommendations

The measured data provides clear guidance on optimal settings for different priorities. For maximum frame rate, Low settings at 1080p deliver 541 FPS, which is the highest measured value. This preset is suitable for competitive play where response time matters more than visual fidelity. At 1440p, Low settings still produce 366.1 FPS, maintaining the ability to drive high-refresh-rate monitors. Even at 4K, Low settings achieve 205.2 FPS, which exceeds the refresh rate of most standard displays.

For a balance between visual quality and performance, Medium settings offer compelling results. At 1080p, Medium produces 495.2 FPS, which is only 45.8 FPS lower than Low. At 1440p, Medium averages 331.6 FPS, a reduction of 34.5 FPS compared to Low. At 4K, Medium achieves 184.4 FPS, still well above 144 Hz refresh rates. The performance cost of moving from Low to Medium is modest across all resolutions, suggesting Medium provides the best compromise for most users.

High settings introduce a more noticeable performance penalty. At 1080p, High averages 437.5 FPS, which is 103.5 FPS lower than Low. At 1440p, High drops to 290 FPS, a 76.1 FPS reduction. At 4K, High produces 168 FPS, which is 37.2 FPS lower than Medium. The visual improvements from High may be worthwhile for users with higher refresh rate displays at 1080p or 1440p, but the 4K result approaches the threshold where some users might prefer Medium.

Ultra settings carry the heaviest performance cost. At 1080p, Ultra averages 356.7 FPS, which is still very high but 184.3 FPS lower than Low. At 1440p, Ultra drops to 236.3 FPS, and at 4K, it falls to 132.5 FPS. The 4K Ultra result is the only measured configuration below 144 FPS, though it remains above 120 FPS. Users prioritizing visual fidelity on high-resolution displays may accept this trade-off, but the data suggests Medium or High provides a better performance-to-quality balance for most scenarios.
