CPU Role

The AMD Ryzen 7 9700F is built on the Zen 5 architecture (Granite Ridge codename) using a 4nm process from TSMC. It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.50 GHz. The processor has a 65W TDP and supports DDR5 memory through a dual-channel interface, delivering 89.6 GB/s memory bandwidth. The L3 cache is 32 MB shared across all cores, with 80 KB L1 and 1 MB L2 per core.

The CPU's single-thread score in Passmark is 4,691, which is relevant for Roblox's engine, as the game relies heavily on single-threaded physics and script execution. The multithread score of 36,470 indicates strong parallel processing capability, but Roblox's sandbox gameplay often bottlenecks on a single core. The 9700F's high boost clock of 5.50 GHz provides the raw clock speed needed to maintain high frame rates in CPU-bound scenarios.

The processor sits in the 94th percentile among all CPUs, with an average benchmark score of 69,996. The nearest rivals show extremely tight competition: the AMD Ryzen 9 7940HX is 0.2% faster, the Intel Core i7-14700KF is 0.2% slower, the AMD Ryzen 9 7950X is 0.7% slower, and the Intel Core i7-14700K is 0.9% slower. This grouping means the 9700F delivers performance essentially identical to these flagship desktop and mobile processors, suggesting that CPU headroom is not a limiting factor in most Roblox scenarios.

In Roblox specifically, the CPU's Passmark physics score of 2,122 and floating point math score of 77,955 indicate competent handling of the game's block-based physics simulations. The processor's data encryption score of 21,488 and extended instructions score of 33,688 show robust general compute capability, though these are less directly relevant to gaming performance. The find prime numbers score of 183 is notably low, but this test does not map to typical game workloads.

GPU Role

The AMD Radeon RX 6600 utilizes the Navi 23 chip built on TSMC's 7nm process, featuring 11,060 million transistors on a 237 mm² die. The GPU has a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. Memory consists of 8 GB of GDDR6 on a 128-bit bus, providing 224.0 GB/s of bandwidth. The card includes 1,792 shading units, 112 texture mapping units, and 64 render output units, with 28 ray tracing cores.

The RX 6600's FP32 performance of 8.928 TFLOPS and texture rate of 279.0 GTexel/s are modest by modern standards, placing the card in the 63rd percentile among all GPUs. The average benchmark score of 19,036 is nearly identical to the NVIDIA Quadro K6000 (19,030, 0% delta) and the NVIDIA GeForce RTX 4050 Mobile (19,049, -0.1% delta). The NVIDIA Tesla K20m trails by 0.3%, while the NVIDIA RTX 2000 Ada Generation leads by 0.4%. This grouping indicates the RX 6600 delivers mainstream-level GPU performance.

For Roblox, the GPU's DirectX 11 score of 152 and DirectX 12 score of 51 in Passmark are relevant since the game supports both APIs. The DirectX 9 score of 197 is notable because Roblox's legacy rendering paths can utilize older DirectX features. The GPU compute score of 6,554 shows moderate compute capability, while the 3DMark Steel Nomad DX12 score of 1,492 provides a modern benchmark reference.

The 8 GB VRAM capacity is adequate for Roblox at all tested resolutions, as the game's blocky textures and simple geometry do not demand large memory allocations. The GPU's 224.0 GB/s bandwidth is sufficient for the game's data requirements, even at 4K Ultra settings where the measured average FPS of 69 suggests the GPU is managing the load without memory bottlenecks. The card's PCIe 4.0 x8 interface provides adequate bandwidth for this workload.

Measured FPS Breakdown

At 1920x1080, the RX 6600 delivers high frame rates across all settings. Low settings produce an average of 281 FPS, Medium averages 256 FPS with a minimum of 218 and maximum of 294, High averages 226 FPS, and Ultra averages 184 FPS. The progression from Low to Ultra shows a 34.5% reduction in average FPS, with the gap between Medium and High (30 FPS) being slightly larger than the gap between High and Ultra (42 FPS).

At 2560x1440, the performance scales down predictably. Low settings average 188 FPS, Medium averages 171 FPS (minimum 145, maximum 197), High averages 151 FPS, and Ultra averages 123 FPS. The Ultra setting at 1440p still maintains an average above 120 FPS, which is important for high-refresh-rate monitors. The minimum FPS of 145 at Medium settings indicates that frame pacing remains stable even when the average is above 170 FPS.

At 3840x2160, the GPU begins to show its limits. Low settings average 106 FPS, Medium averages 97 FPS (minimum 82, maximum 111), High averages 85 FPS, and Ultra averages 69 FPS. The 4K Ultra result of 69 FPS is still playable, but the minimum FPS at 4K Medium (82) suggests that frame dips become more noticeable at this resolution. The range between Low and Ultra at 4K is 37 FPS, which is the largest absolute spread across all resolutions.

The data shows that the RX 6600 maintains playable frame rates at every resolution and settings combination tested. Even the most demanding configuration (4K Ultra) delivers an average above 60 FPS, while the least demanding (1080p Low) reaches 281 FPS. The minimum FPS values are only recorded for Medium settings at each resolution, showing a consistent pattern: 218 at 1080p, 145 at 1440p, and 82 at 4K.

Resolution Scaling

The FPS drop from 1080p to 4K varies significantly by settings preset. At Low settings, the average drops from 281 FPS at 1080p to 106 FPS at 4K, a 62.3% reduction. At Medium settings, the drop is from 256 to 97 FPS, a 62.1% reduction. High settings fall from 226 to 85 FPS, a 62.4% reduction. Ultra settings decline from 184 to 69 FPS, a 62.5% reduction. This remarkable consistency — all settings levels showing roughly 62% performance loss — indicates that resolution scaling is uniform regardless of visual complexity.

The consistent percentage drop across all settings suggests that the GPU is the primary limiting factor when moving from 1080p to 4K. The RX 6600's pixel rate of 159.4 GPixel/s becomes the bottleneck at higher resolutions, as the number of pixels quadruples from 1080p to 4K. The texture rate of 279.0 GTexel/s also scales with resolution, further pressuring the GPU at 4K.

However, the absolute FPS values at 4K (69-106 FPS depending on settings) remain playable, which indicates that the CPU is still keeping up with the GPU's output. The Ryzen 7 9700F's single-thread performance of 4,691 in Passmark is sufficient to feed the GPU at these frame rates. The fact that 4K Low still delivers 106 FPS suggests that the GPU is not being fully saturated, and the CPU has additional headroom.

The scaling behavior points to a balanced combination. At 1080p, the CPU becomes more relevant as frame rates approach 300 FPS, where per-frame CPU overhead matters. At 4K, the GPU workload dominates, but the RX 6600 still manages to produce smooth results. The mid-resolution of 1440p appears to be the sweet spot, with Ultra settings maintaining 123 FPS average.

Settings Recommendations

The best experience depends on the target resolution and refresh rate. For 1080p displays, Ultra settings at 184 FPS average is the optimal choice, as the frame rate remains high enough for 144Hz monitors while providing maximum visual quality. The drop from Medium (256 FPS) to Ultra (184 FPS) is acceptable given that both exceed typical refresh rate limits.

For 1440p, the Ultra preset at 123 FPS average is recommended for 120Hz displays, but High settings at 151 FPS provides additional headroom for 144Hz panels. The Medium preset at 171 FPS is the best option for competitive play where frame rate takes priority over visual fidelity, though the minimum of 145 FPS at Medium still ensures smooth gameplay.

For 4K, the High preset at 85 FPS offers the best balance between visual quality and performance, as it stays above 60 FPS while providing improved detail over Medium. The Ultra preset at 69 FPS is playable but leaves little margin for frame dips in busy scenes. The Low preset at 106 FPS is recommended for players who prioritize frame rate consistency at 4K.

The minimum FPS data for Medium settings across resolutions shows that frame dips are more pronounced at higher resolutions: 218 at 1080p, 145 at 1440p, and 82 at 4K. This suggests that players sensitive to frame pacing should consider High settings at 4K (85 FPS average) rather than Ultra, as the 16 FPS difference between these presets at 4K may translate to more stable frame delivery at High. The measured data supports High as the most balanced preset at 1440p and 4K, while Ultra is viable at 1080p due to the high absolute frame rates.
