# Roblox Performance Analysis: Intel Core i7-13700K + AMD Radeon RX 6750 XT

This combination of an Intel Core i7-13700K and AMD Radeon RX 6750 XT delivers exceptionally high frame rates in Roblox, with measured performance ranging from 92.9 FPS at 4K Ultra to 386.6 FPS at 1080p Low. The data reveals a system that is heavily overqualified for this sandbox title, as even the most demanding preset at 4K resolution stays comfortably above 90 FPS. The benchmark results place this combo at rank 891 out of 1800 tested combinations, which suggests that while the absolute numbers are strong, other hardware pairings achieve even higher performance in this specific game.

Settings Recommendations

The measured FPS data across all resolutions and settings presets shows that Roblox presents minimal challenge to this hardware. At 1080p, the gap between Low (386.6 FPS) and Ultra (252.2 FPS) represents a drop of approximately 35%, yet even Ultra settings deliver over two and a half times the refresh rate of a standard 60Hz display. At 1440p, Ultra still produces 167.6 FPS, which exceeds the refresh rate of most high-end monitors. The 4K results are where settings choices become meaningful: Ultra drops to 92.9 FPS, while High maintains 114.6 FPS, Medium reaches 132.5 FPS, and Low peaks at 145.2 FPS.

For users with 1080p or 1440p displays, the Ultra preset is clearly the recommended choice, as the frame rate remains far above any practical refresh rate ceiling. The data shows no reason to sacrifice visual quality at these resolutions. At 4K, the decision depends on the display's refresh rate. For 60Hz displays, even Ultra at 92.9 FPS provides headroom above the refresh limit. For 120Hz or 144Hz 4K panels, High settings at 114.6 FPS offer the best balance, while Medium at 132.5 FPS becomes attractive for those prioritizing higher frame rates. The Low preset at 4K yields 145.2 FPS, but the visual compromise seems unnecessary given how close High and Medium remain to that figure.

GPU Role

The AMD Radeon RX 6750 XT brings 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The GPU operates with a base clock of 2150 MHz, a game clock of 2495 MHz, and a boost clock of 2600 MHz. These specifications place the GPU in the 79th percentile among all tested GPUs, with an average benchmark score of 35327. The nearest rivals include the AMD Radeon RX 5600M (0.2% higher score), NVIDIA GeForce RTX 5070 Ti Mobile (0.3% lower), AMD Radeon 880M (0.9% lower), and NVIDIA GeForce RTX 3080 (1.3% lower). This clustering indicates the RX 6750 XT performs within a narrow band of its immediate competitors.

In Roblox specifically, the GPU appears to be the primary scaling factor when moving between settings presets. The difference between Low and Ultra at the same resolution is substantial: at 1080p, the spread is 134.4 FPS (from 252.2 to 386.6), at 1440p it is 91.4 FPS (from 167.6 to 259), and at 4K it is 52.3 FPS (from 92.9 to 145.2). This pattern shows that as resolution increases, the absolute FPS gap between settings narrows, which is consistent with the GPU becoming more heavily loaded at higher pixel counts. The RDNA 2.0 architecture, built on a 7 nm process with 17,200 million transistors, demonstrates it has ample compute resources for Roblox's rendering demands.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals interesting scaling behavior. At High settings, performance drops from 312.6 FPS at 1080p to 208.6 FPS at 1440p (a 33.3% reduction) and then to 114.6 FPS at 4K (a 45.1% reduction from 1440p). At Low settings, the progression goes from 386.6 to 259 to 145.2 FPS, representing drops of 33.0% and 43.9% respectively. The Ultra preset shows the steepest relative decline: 252.2 to 167.6 to 92.9 FPS, with reductions of 33.5% and 44.6%.

The consistent pattern of roughly one-third reduction from 1080p to 1440p and another 44-45% reduction from 1440p to 4K indicates that the rendering load scales predictably with pixel count. The fact that these percentage drops are nearly identical across all settings presets suggests that the limiting component remains the same regardless of visual quality level. Given that the CPU is a high-end 16-core processor, the data points to the GPU as the primary constraint when resolution increases, though the absolute frame rates remain so high that neither component is truly stressed in this game.

CPU Role

The Intel Core i7-13700K features 16 cores and 24 threads with a base clock of 3.40 GHz and boost clock of 5.40 GHz. This Raptor Lake-S processor, built on a 10 nm process, includes 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 30 MB of shared L3 cache. The CPU achieves an average benchmark score of 47282, placing it in the 93rd percentile of all CPUs. Its nearest rivals in synthetic benchmarks are the Intel Core i7-13700KF (47334, 0.1% higher), AMD EPYC 4364P (47131, 0.3% lower), Intel Core i9-12900F (47081, 0.4% lower), and AMD Ryzen 9 PRO 5945 (47527, 0.5% higher).

In Roblox, the CPU's role appears secondary to the GPU based on the resolution scaling patterns. The single-thread performance, as measured by Cinebench R23 single-core score of 5505 and Geekbench single-core of 2850, is strong enough that even the highest frame rates at 1080p Low (386.6 FPS) do not appear CPU-limited. The multi-threaded capabilities, evidenced by a Cinebench R23 multi-core score of 39000 and PassMark multithread score of 45887, are far beyond what a game like Roblox requires. The fact that frame rates scale so consistently with resolution suggests the CPU maintains adequate headroom across all tested configurations.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are: Low 386.6 FPS, Medium 351.7 FPS, High 312.6 FPS, and Ultra 252.2 FPS. The progression shows diminishing returns when lowering settings — moving from Ultra to High gains 60.4 FPS, High to Medium gains 39.1 FPS, and Medium to Low gains 34.9 FPS.

At 2560x1440, the results are: Low 259 FPS, Medium 234.7 FPS, High 208.6 FPS, and Ultra 167.6 FPS. The gaps between presets shrink to 24.3 FPS (Ultra to High), 26.1 FPS (High to Medium), and 24.3 FPS (Medium to Low). This tightening suggests the GPU is becoming more of a factor as pixel count increases.

At 3840x2160, the values drop to: Low 145.2 FPS, Medium 132.5 FPS, High 114.6 FPS, and Ultra 92.9 FPS. The differences between adjacent presets are 12.7 FPS (Ultra to High), 17.9 FPS (High to Medium), and 12.7 FPS (Medium to Low). The overall pattern shows that at 4K, the absolute FPS differences between settings become smaller, indicating that resolution is now the dominant variable.

How This Combo Ranks

With a rank of 891 out of 1800 tested combinations, this hardware pairing sits almost exactly at the median of all tested combos in Roblox. This ranking is notable because the absolute frame rates are extremely high — well above what most displays can even show. The explanation likely lies in the fact that Roblox performance can be influenced by many factors beyond raw GPU and CPU power, and many other tested combinations may include hardware that is particularly well-suited to this game's specific rendering engine.

The rank suggests that while the i7-13700K and RX 6750 XT deliver outstanding raw performance, there are 890 other combinations that achieve even higher frame rates in Roblox. Given that the CPU sits in the 93rd percentile and the GPU in the 79th percentile, the combo rank of 891 indicates that this pairing is not optimally tuned for Roblox specifically, despite its excellent synthetic benchmark results. The wide gap between the hardware's general-purpose performance and its specific ranking in this game implies that Roblox's engine may favor different hardware characteristics than those emphasized in standard benchmarks. For users focused purely on Roblox, exploring other GPU options might yield better results, though the measured frame rates here are already so high that real-world differences would be imperceptible on most monitors.
