This analysis breaks down the CPU and GPU contributions, resolution scaling behavior, and provides specific settings recommendations based on the measured FPS data.

CPU Role

The AMD Ryzen 7 3700X serves as the central processing unit in this configuration, featuring 8 cores and 16 threads with a base clock of 3.60 GHz and a boost clock of 4.40 GHz. This Zen 2 architecture processor, built on a 7 nm process, demonstrates strong multi-threaded capabilities with a Cinebench R23 multicore score of 19,087 and a single-core score of 2,694. The processor's performance places it in the 85th percentile of all CPUs, with an average benchmark score of 28,631 that nearly matches the Intel Core i5-12600 (28,654, deltaPct -0.1) and slightly exceeds the AMD Ryzen 5 5600XT (28,591, deltaPct 0.1).

In Roblox, the CPU's role becomes particularly evident at lower resolutions where the GPU can render frames quickly. The data shows that at 1080p Low settings, the system achieves 503.3 FPS, which represents the highest measured frame rate across all configurations. This suggests that at this resolution and settings level, the Ryzen 7 3700X is capable of feeding frames to the GPU at an extremely high rate. The 32 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide adequate data throughput for the game's physics and scripting workloads.

The processor's multi-threading capabilities prove beneficial for Roblox's sandbox nature, where multiple player scripts, world physics, and network processing can utilize the available 16 threads. The PassMark multithread score of 22,458 and physics score of 1,181 indicate solid performance in scenarios that rely on parallel processing. At higher resolutions like 4K Ultra, where the GPU becomes the primary bottleneck, the CPU's single-thread performance of 2,656 in PassMark ensures it does not become a limiting factor, with the system still maintaining 123.7 FPS in the most demanding test.

GPU Role

The NVIDIA GeForce RTX 4070 provides the graphics processing power for this combination, built on the Ada Lovelace architecture with 5,888 shading units and 46 RT cores. The GPU operates with a base clock of 1920 MHz and a boost clock of 2475 MHz, paired with 12 GB of GDDR6X memory on a 192-bit bus delivering 504.2 GB/s bandwidth. This configuration places the RTX 4070 in the 81st percentile of all GPUs, with an average benchmark score of 37,283 that closely rivals the AMD Radeon RX Vega 56 (37,507, deltaPct -0.6) and sits just behind the NVIDIA GeForce RTX 4080 Mobile (38,135, deltaPct -2.2).

The GPU's 12 GB VRAM capacity proves more than sufficient for Roblox, which is not a VRAM-intensive title even at 4K Ultra settings. The measured FPS at 4K Ultra (123.7 FPS) demonstrates that the RTX 4070's raw compute power, rated at 29.15 TFLOPS FP32, is the dominant factor at this resolution. The GPU's texture rate of 455.4 GTexel/s and pixel rate of 158.4 GPixel/s allow it to handle the game's rendering demands efficiently across all settings levels.

At 1080p, the GPU's capabilities are somewhat underutilized due to CPU limitations, with the gap between Low (503.3 FPS) and High (406.4 FPS) settings being relatively modest at 96.9 FPS. However, at 4K, the GPU's workload increases substantially, and the difference between Low (192.4 FPS) and High (154.1 FPS) settings becomes more pronounced at 38.3 FPS. This pattern confirms that the RTX 4070 scales well with resolution in Roblox, maintaining playable frame rates even at the highest settings.

Resolution Scaling

The measured FPS data reveals distinct scaling patterns as resolution increases from 1080p to 4K. At Low settings, frame rates drop from 503.3 FPS at 1080p to 338.7 FPS at 1440p, then further to 192.4 FPS at 4K. This represents a 61.8% reduction from 1080p to 4K, indicating that the GPU becomes increasingly loaded as pixel count rises. The scaling at Ultra settings follows a similar trajectory: 329.8 FPS at 1080p, 219.5 FPS at 1440p, and 123.7 FPS at 4K.

The resolution scaling pattern suggests that at 1080p, the system is partially CPU-bound, particularly at lower settings where the frame rate exceeds 500 FPS. The Ryzen 7 3700X's single-thread performance becomes a limiting factor at these extremely high frame rates. As resolution increases to 1440p, the GPU begins to take on more of the workload, with the frame rate gap between Low and Ultra settings narrowing from 173.5 FPS at 1080p to 119.2 FPS at 1440p. At 4K, the GPU is clearly the dominant bottleneck, with the gap between Low and Ultra settings shrinking to 68.7 FPS.

The data also shows that the percentage drop from 1080p to 4K varies by settings level. At Low settings, the drop is 61.8%, while at High settings, it is 62.1%, and at Ultra, it is 62.5%. This consistency suggests that Roblox's rendering workload scales predictably with resolution across all settings levels, with the RTX 4070 handling the increased pixel count efficiently. The system maintains playable frame rates at all tested configurations, with even the lowest performance scenario (4K Ultra at 123.7 FPS) far exceeding typical display refresh rates.
