Resolution Scaling

The measured FPS data for Roblox with the Intel Core i9-14900K and AMD Radeon RX 6700 XT shows a clear progression as resolution increases. At 1920x1080 with Low settings, the combo delivers 366.4 FPS average. Moving to 2560x1440 Low drops that to 247.9 FPS, a reduction of roughly 32%. At 3840x2160 Low, the average falls further to 142.5 FPS, another 42% decline from the 1440p figure. This scaling pattern indicates that even at Low settings, the game becomes increasingly dependent on the GPU as pixel count rises.

The High preset tells a similar story but with lower absolute numbers. At 1080p High, the system produces 298 FPS. At 1440p High, that drops to 195.8 FPS, a 34% decrease. At 4K High, the average is 110 FPS, a 44% drop from the 1440p result. The consistency of these percentage drops across settings suggests the Radeon RX 6700 XT is the primary limiting factor at higher resolutions, while the Core i9-14900K has ample headroom to feed frames at 1080p.

Ultra settings amplify the resolution penalty. The 1080p Ultra result is 242.6 FPS, which falls to 161.5 FPS at 1440p (33% lower) and then to 92.8 FPS at 4K (another 43% lower). The gap between Low and Ultra at each resolution is also instructive: at 1080p, the difference is 123.8 FPS (366.4 vs 242.6), while at 4K it narrows to 49.7 FPS (142.5 vs 92.8). This compression at 4K indicates that the GPU is saturated regardless of settings, and the CPU's ability to push higher frame rates is constrained by the rendering workload.

GPU Role

The AMD Radeon RX 6700 XT carries 12 GB of GDDR6 memory on a 192-bit bus, yielding 384.0 GB/s of bandwidth. The card's base clock is 2321 MHz, with a game clock of 2424 MHz and a boost clock of 2581 MHz. In Roblox, these specifications translate to strong performance across all measured configurations, but the data reveals where the GPU's influence is most pronounced.

At 4K, the GPU's role becomes dominant. The spread between Low and Ultra at 3840x2160 is just 49.7 FPS, compared to a 123.8 FPS spread at 1080p. This suggests that at 4K, the RX 6700 XT is the bottleneck, and raising settings from Low to Ultra costs relatively less performance because the pixel throughput is already taxing the card. The 12 GB frame buffer is sufficient for Roblox's requirements at all tested settings, as even the heaviest preset at 4K maintains an average above 90 FPS.

The GPU's texture rate of 413.0 GTexel/s and pixel rate of 165.2 GPixel/s are relevant for a game like Roblox, which uses simple geometry but can have dense scenes. The 2560 shading units and 160 texture mapping units handle the game's visual effects without issue. The card's FP32 throughput of 13.21 TFLOPS is more than adequate for Roblox's shader complexity, and the measured results confirm that the GPU is not holding back the system until 4K Ultra, where the 92.8 FPS average still exceeds typical display refresh rates.

How This Combo Ranks

The combination of the Intel Core i9-14900K and AMD Radeon RX 6700 XT ranks 979 out of 1800 tested combos in Roblox. This places it in the 54th percentile of all combinations, meaning roughly 46% of tested setups deliver higher frame rates in this game. Given that the CPU sits in the 97th percentile among all processors and the GPU in the 77th percentile among all GPUs, the combo ranking is lower than either component's individual standing would suggest.

The CPU's nearest rivals in synthetic benchmarks provide context. The AMD EPYC 7413 scores 80041 on average, just 0.3% above the i9-14900K's 79824. The Intel Core i9-14900KF trails by 0.7%, and the Intel Core Ultra 7 265KF and 265K also sit within 0.7% and 0.9%, respectively. These differences are negligible in real-world gaming, and Roblox is not a CPU-bound title at these resolutions.

On the GPU side, the RX 6700 XT's average benchmark score of 33721 puts it just 0.7% behind the Radeon RX 6800 and 1% ahead of the Radeon HD 7950 and RX 480. The NVIDIA RTX A5000 is 1.3% behind. These narrow margins suggest that swapping to any of these rivals would produce similar Roblox performance, and the combo rank is more influenced by the GPU tier than the CPU choice.

Settings Recommendations

The measured data shows that Low settings provide the highest frame rates at every resolution, but the differences between presets are not uniform. At 1080p, Low delivers 366.4 FPS, Medium 334.6 FPS, High 298 FPS, and Ultra 242.6 FPS. The step from Low to Medium costs 31.8 FPS, which is a modest 8.7% reduction. From Medium to High, the drop is 36.6 FPS (10.9%), and from High to Ultra, another 55.4 FPS (18.6%). The Ultra preset's penalty is disproportionately large, suggesting diminishing returns beyond High.

At 1440p, the pattern holds. Low produces 247.9 FPS, Medium 226.7 FPS, High 195.8 FPS, and Ultra 161.5 FPS. The gap between Low and Medium is 21.2 FPS (8.5%), between Medium and High is 30.9 FPS (13.6%), and between High and Ultra is 34.3 FPS (17.5%). For gamers with 144Hz displays, High settings are the sweet spot; the 195.8 FPS average comfortably exceeds refresh rate needs while providing better visuals than Medium.

At 4K, the recommendation shifts. Low yields 142.5 FPS, Medium 128 FPS, High 110 FPS, and Ultra 92.8 FPS. All presets remain playable, but the relative cost of Ultra is lower than at lower resolutions. The 49.7 FPS difference between Low and Ultra at 4K is significant in absolute terms, yet the 92.8 FPS floor still satisfies 60Hz displays. For 4K gaming, Medium or High offers the best balance, as the visual uplift from Medium to High costs only 18 FPS.

Measured FPS Breakdown

At 1920x1080, the system produces its fastest results. Low settings average 366.4 FPS. Medium settings average 334.6 FPS, which is 31.8 FPS lower. High settings average 298 FPS, another 36.6 FPS lower. Ultra settings average 242.6 FPS, a further 55.4 FPS reduction. The total spread from Low to Ultra is 123.8 FPS.

At 2560x1440, the averages are 247.9 FPS for Low, 226.7 FPS for Medium, 195.8 FPS for High, and 161.5 FPS for Ultra. The spread narrows to 86.4 FPS. The step from Low to Medium costs 21.2 FPS, Medium to High costs 30.9 FPS, and High to Ultra costs 34.3 FPS.

At 3840x2160, the averages are 142.5 FPS for Low, 128 FPS for Medium, 110 FPS for High, and 92.8 FPS for Ultra. The spread is 49.7 FPS. The step from Low to Medium costs 14.5 FPS, Medium to High costs 18 FPS, and High to Ultra costs 17.2 FPS. The 4K results show the smallest absolute differences between presets, reinforcing that the GPU is the limiting factor at this resolution.
