# Roblox with Intel Core i5-14600KF + AMD Radeon RX 6750 XT

The Intel Core i5-14600KF paired with the AMD Radeon RX 6750 XT delivers an exceptionally strong Roblox experience across all tested resolutions and settings. The measured data shows average frame rates ranging from a minimum of 97.5 FPS at 4K Ultra to a maximum of 384.7 FPS at 1080p Low, indicating that this combination is capable of maintaining high fluidity even under the most demanding visual presets. The combo ranks 893rd out of 1800 tested configurations, placing it in the upper half of all systems, while the CPU holds the 93rd percentile among all processors and the GPU sits in the 79th percentile among all graphics cards. These benchmark results reveal a system where the CPU’s strong single-thread performance and the GPU’s substantial memory bandwidth both contribute to Roblox’s particular rendering demands.

Resolution Scaling

The frame rate progression from 1080p to 4K follows a predictable pattern of decreasing performance as pixel count rises, but the magnitude of the drop reveals important characteristics about the system’s bottleneck. At High settings, the average FPS falls from 311 at 1920x1080 to 205.1 at 2560x1440, a reduction of 105.9 FPS (34%), and then further to 119.7 at 3840x2160, another 85.4 FPS drop (41.6%). This steady decline indicates that the GPU becomes progressively more stressed as resolution increases, yet even at 4K High the system maintains above 119 FPS, suggesting no hard bottleneck emerges in this range.

The scaling from 1080p to 1440p at Low settings shows a milder decline: 384.7 FPS down to 259.4 FPS, a 32.6% reduction. Moving from 1440p to 4K at Low, the drop is from 259.4 to 146.1 FPS, a 43.7% reduction. This pattern of larger percentage losses at higher resolutions is typical of a GPU-bound scenario, where the RX 6750 XT’s 432.0 GB/s memory bandwidth and 13.31 TFLOPS FP32 compute are being fully utilized. At 1080p, the CPU’s role becomes more prominent: the i5-14600KF’s 5.30 GHz boost clock and strong single-core scores (4643 in Cinebench R23 single-core) help push frame rates above 300 FPS at Low and Medium settings, indicating that the processor is not the limiting factor even at lower pixel counts.

The Ultra preset shows the steepest resolution penalty. From 251.1 FPS at 1080p, the frame rate drops to 166.4 at 1440p (33.7% loss) and then to 97.5 at 4K (41.4% loss from 1440p). This suggests that the Ultra preset’s additional effects taxes the GPU disproportionately at higher resolutions, but the system still delivers playable frame rates at 4K Ultra, which is notable for a card that sits below the 80th percentile in overall GPU benchmarks.

CPU Role

The Intel Core i5-14600KF brings 14 cores and 20 threads from the Raptor Lake architecture, running at a base clock of 3.50 GHz and boosting to 5.30 GHz. This processor, released in October 2023, demonstrates substantial multi-threaded capability with a Cinebench R23 multi-core score of 32889, yet its single-core score of 4643 is what matters most for Roblox’s typically light-threaded rendering workload. The measured FPS data supports this: at 1080p Low, the system achieves 384.7 FPS, which is far above any refresh rate requirements, indicating that the CPU is feeding the GPU with sufficient frames even in less demanding settings.

The CPU’s position in the 93rd percentile among all processors, with an average benchmark score of 49367, places it ahead of the Core i5-14600K (49166) by 0.4% and the Ryzen 9 5950X (49062) by 0.6%. This margin is small, suggesting that the i5-14600KF is well-matched to its direct competitors in synthetic benchmarks, and the 0.4% delta over the 14600K is likely due to the KF’s lack of integrated graphics, which frees up thermal and power headroom. The processor’s 24 MB of shared L3 cache and 2 MB per-core L2 cache provide ample data locality for game workloads, while its DDR4 and DDR5 memory support offers flexibility for system builders.

In Roblox specifically, the CPU’s role becomes more apparent when comparing resolution scaling. At 1080p, moving from Low (384.7 FPS) to Ultra (251.1 FPS) shows a 133.6 FPS drop, which is a relatively modest penalty compared to the 4K drop from Low (146.1 FPS) to Ultra (97.5 FPS) of 48.6 FPS. This suggests that at lower resolutions, the CPU has enough headroom to keep frame rates high even as GPU load increases, but at 4K the GPU becomes the dominant factor. The i5-14600KF’s strong single-thread performance, evidenced by its 2778 Geekbench single-core score, ensures that Roblox’s physics and logic threads are never starved, even when the GPU is producing over 300 FPS.

Measured FPS Breakdown

At 1920x1080, the RX 6750 XT and i5-14600KF deliver exceptional performance across all settings. Low settings produce 384.7 FPS average, Medium reaches 349.9 FPS, High drops to 311 FPS, and Ultra still maintains 251.1 FPS. The spread between Low and Ultra is 133.6 FPS, which indicates that Roblox’s graphical presets have a meaningful impact on frame rate, but even the most demanding settings exceed 250 FPS at this resolution.

Moving to 2560x1440, the frame rates remain high but show the expected scaling. Low settings average 259.4 FPS, Medium 231.7 FPS, High 205.1 FPS, and Ultra 166.4 FPS. The difference between Low and Ultra narrows to 93 FPS in absolute terms, but the percentage gap widens slightly, with Ultra representing a 35.9% reduction from Low. At this resolution, the system is still capable of exceeding 165 FPS on Ultra, which aligns with high-refresh-rate monitors.

At 3840x2160, the performance remains playable but the GPU’s workload becomes evident. Low settings yield 146.1 FPS, Medium 135.4 FPS, High 119.7 FPS, and Ultra drops to 97.5 FPS. The gap between Low and Ultra is 48.6 FPS, and the percentage reduction from Low to Ultra is 33.3%. Notably, the 4K Ultra result of 97.5 FPS is just below the 100 FPS threshold, but it remains well above 60 FPS, making this combination suitable for 4K gaming with some quality trade-offs.

The consistency of the data across settings is noteworthy: at every resolution, the ordering is Low > Medium > High > Ultra, with no anomalies. The ratios between settings are also stable, suggesting that Roblox’s presets scale linearly in terms of GPU load. For instance, at 1080p, Medium is 91% of Low, High is 80.8% of Low, and Ultra is 65.3% of Low. At 4K, these ratios become 92.7%, 81.9%, and 66.7% respectively, showing very similar scaling behavior.

GPU Role

The AMD Radeon RX 6750 XT, based on the Navi 22 chip with RDNA 2.0 architecture, provides 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. Its boost clock reaches 2600 MHz, with a game clock of 2495 MHz, and it offers 2560 shading units, 160 TMUs, and 64 ROPs. The card’s 13.31 TFLOPS FP32 compute and 416.0 GTexel/s texture rate are substantial for a GPU that sits in the 79th percentile among all graphics cards, with an average benchmark score of 35327.

In the context of Roblox, the GPU’s role is primarily defined by its ability to handle the game’s rendering at various resolutions. The 4K results are particularly telling: at 4K High, the card produces 119.7 FPS, which is a strong result for a game that is not typically considered GPU-heavy. The 4K Ultra result of 97.5 FPS shows that the RX 6750 XT can handle the most demanding settings, though it falls short of the 100 FPS mark. The card’s nearest rivals in benchmark scores are the RX 5600M (35264, 0.2% lower), the RTX 5070 Ti Mobile (35435, 0.3% higher), and the Radeon 880M (35646, 0.9% higher), indicating that the RX 6750 XT is closely matched with these competitors in synthetic tests.

The GPU’s memory bandwidth appears to be a critical factor in Roblox’s performance. At 1080p Low, the system achieves 384.7 FPS, which is likely limited by the CPU’s ability to issue draw calls rather than the GPU’s memory throughput. However, at 4K, the 432.0 GB/s bandwidth is sufficient to maintain 146.1 FPS at Low settings, showing that the memory subsystem does not become a bottleneck even at higher resolutions. The card’s 40 ray accelerators are not directly relevant to Roblox’s standard rendering path, but the 12 GB VRAM capacity ensures that texture-heavy scenes at 4K do not exceed memory limits, as evidenced by the consistent frame rates across all settings at each resolution.
