Roblox

Roblox is a notoriously CPU-bound sandbox title, and the measured frame rates for the Intel Core i5-14600KF paired with the AMD Radeon RX 7700 XT demonstrate exactly how this dynamic plays out across common gaming resolutions. The data shows a system with ample headroom for high-refresh-rate monitors, but the scaling pattern from 1080p to 4K reveals where the workload truly sits.

Resolution Scaling

The frame rate progression from 1920x1080 to 3840x2160 follows a predictable curve, but the magnitude of the drop is less severe than in most modern AAA titles, which points to a unique bottleneck profile. At High settings, the average FPS falls from 339.2 at 1080p to 223.6 at 1440p, and finally to 128.1 at 4K. That represents a 34% reduction from 1080p to 1440p, followed by a further 43% drop from 1440p to 4K. These are substantial declines, but the absolute numbers remain high enough that even the 4K result stays comfortably above 120 FPS.

The scaling behavior across the settings presets tells a more nuanced story. At Low settings, the 1080p result reaches 419.8 FPS, which is the highest number recorded for this combo. Dropping to 1440p Low yields 279.2 FPS, a 33% reduction, while 4K Low lands at 159.3 FPS, another 43% step down. This pattern repeats almost identically for Medium and High presets, suggesting that the resolution scaling factor is remarkably consistent regardless of graphical load. The consistency implies that the GPU is not the primary limiter at lower resolutions, but becomes progressively more engaged as pixel count rises.

The most telling data point comes from comparing the Ultra preset across resolutions. At 1080p Ultra, the combo produces 274.5 FPS, which is still far above any standard monitor refresh rate. At 4K Ultra, the average drops to 105.3 FPS. The delta between 1080p and 4K at Ultra is 169.2 FPS, which is the largest absolute gap across all presets. This indicates that Ultra settings add enough GPU work that the card's capabilities start to matter more, but even then, the 4K result remains playable. The overall picture is that this combination has enough raw throughput to push Roblox to very high frame rates at any resolution, with the CPU clearly holding the reins at 1080p and the GPU gradually taking over as resolution increases.

GPU Role

The AMD Radeon RX 7700 XT brings 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The card's boost clock reaches 2544 MHz, with a game clock rated at 2171 MHz. For a game like Roblox, which features relatively simple geometry and textures compared to modern shooters or RPGs, the 12 GB capacity is more than sufficient. The benchmark data shows the GPU never becomes a hard bottleneck even at 4K Ultra, where the average FPS remains above 100.

The GPU's performance percentile sits at 73, meaning it outperforms roughly three-quarters of all GPUs in the database. Its average benchmark score of 30097 places it in a tight cluster with the NVIDIA GeForce RTX 5060, which scores 30109 and shows a deltaPct of 0. That near-identical score suggests the two cards trade blows depending on the workload. The RX 7700 XT also sits close to the AMD Radeon RX 570, which has an average score of 30158 and a deltaPct of -0.2, though that comparison seems anomalous given the generational gap. The more relevant rival is the NVIDIA GeForce RTX 5070 Mobile, which scores 29928 with a deltaPct of 0.6, indicating the desktop RX 7700 XT holds a slight edge.

In Roblox specifically, the GPU's role is secondary to the CPU at lower resolutions. The fact that 1080p Low produces 419.8 FPS while 1080p Ultra produces 274.5 FPS shows that graphical settings have a measurable impact, but the frame rates are so high that the GPU is clearly not struggling. At 4K, the GPU's compute resources become more relevant, with the Ultra preset dropping to 105.3 FPS. The card's 35.17 TFLOPS of FP32 performance and 244.2 GPixel/s pixel rate provide enough raw horsepower to handle Roblox's rendering demands without breaking a sweat.

How This Combo Ranks

The Intel Core i5-14600KF and AMD Radeon RX 7700 XT combination ranks 794 out of 1800 tested combos in Roblox. That places it in the 56th percentile of all combinations, which is a solid result for a mid-to-high-range pairing. The rank reflects that while this system delivers very high absolute frame rates, many other combos with more powerful CPUs or GPUs achieve even higher numbers in this CPU-bound title.

The CPU itself holds a percentile rank of 93 against all CPUs, indicating it sits in the top 7% of processors. Its average benchmark score of 49367 places it just above the Intel Core i5-14600K, which scores 49166 with a deltaPct of 0.4. The AMD EPYC 4345P scores 49595 with a deltaPct of -0.5, meaning the 14600KF trails that server chip by half a percent. The AMD Ryzen 9 5950X scores 49062 with a deltaPct of 0.6, and the Intel Xeon Gold 5318H scores 48698 with a deltaPct of 1.4. These tight margins show that the 14600KF is positioned competitively among high-end desktop and even some workstation processors.

The GPU's percentile of 73 is lower than the CPU's 93, which creates an interesting imbalance. In Roblox, where the CPU often dictates performance, this combo's rank of 794 out of 1800 suggests that the GPU is not holding the system back. If the GPU were the limiting factor, the rank would likely be lower given its 73rd percentile standing. Instead, the data indicates that the CPU's strong single-thread performance is doing the heavy lifting, and the GPU is more than adequate for the task.

Measured FPS Breakdown

At 1920x1080, the measured results show a clear hierarchy across settings. Low settings produce 419.8 FPS, Medium drops to 381.3 FPS, High yields 339.2 FPS, and Ultra brings up the rear at 274.5 FPS. The gap between Low and Ultra is 145.3 FPS, which is substantial but still leaves even the lowest result far above any practical refresh rate ceiling. The 1080p numbers suggest that the CPU is the primary driver here, as the GPU has plenty of spare capacity.

Moving to 2560x1440, the pattern persists but with lower absolute values. Low settings average 279.2 FPS, Medium hits 255 FPS, High delivers 223.6 FPS, and Ultra settles at 183.8 FPS. The delta between Low and Ultra narrows to 95.4 FPS, indicating that the GPU is starting to absorb more of the workload as pixel count increases. The step from 1080p to 1440p at any given setting costs roughly one-third of the frame rate, which is a consistent and predictable scaling curve.

At 3840x2160, the results show the GPU taking on a more significant role. Low settings average 159.3 FPS, Medium reaches 144.1 FPS, High produces 128.1 FPS, and Ultra drops to 105.3 FPS. The gap between Low and Ultra shrinks further to 54 FPS, demonstrating that at 4K, the GPU's processing capability is more evenly matched with the CPU's output. All four 4K results remain above 100 FPS, which is impressive for a sandbox game with minimal graphical complexity. The data confirms that this combo can drive Roblox at high refresh rates even at 4K, with Ultra preset being the only setting that approaches the 100 FPS threshold.

CPU Role

The Intel Core i5-14600KF features 14 cores and 20 threads, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. Its 24 MB of shared L3 cache and 2 MB per-core L2 cache provide ample fast storage for game data. The CPU's multi-threaded performance is strong, as evidenced by its Cinebench R23 multi-core score of 32889 and single-core score of 4643. The single-core result is particularly relevant for Roblox, which has a history of relying heavily on a single thread for main game logic.

The CPU's PassMark single-thread score of 4273 and multithread score of 38697 further illustrate its capabilities. The data compression score of 485140 and encryption score of 27608 show strong general-purpose performance, though these are not directly relevant to gaming. The CPU's 93rd percentile ranking confirms that it is a top-tier processor for most workloads, and Roblox's frame rates reflect this strength.

The benchmark results indicate that the 14600KF is the dominant component in this pairing for Roblox. The fact that 1080p Low produces 419.8 FPS while 4K Ultra produces 105.3 FPS suggests that even at 4K, the CPU is still contributing meaningfully. If the CPU were completely saturating, the frame rates would plateau regardless of resolution or settings. Instead, the consistent scaling across all presets indicates that both components are working in tandem, with the CPU providing the foundation and the GPU adding resolution-dependent headroom.

Settings Recommendations

For users with a 1080p monitor, the data shows that even the Ultra preset at 274.5 FPS exceeds the refresh rate of virtually all gaming displays. The Low preset at 419.8 FPS offers marginal gains that are imperceptible on standard 144Hz or 240Hz panels. In this case, the recommendation is to use Ultra settings, as the visual quality improvements come at no practical cost to the gaming experience.

At 1440p, the Ultra preset delivers 183.8 FPS, which remains well above the 144Hz threshold common on high-refresh monitors. The Medium preset at 255 FPS is only relevant for users with 240Hz or higher displays. For most setups, Ultra provides the best experience, but those chasing maximum frame rates can drop to Low for 279.2 FPS.

The 4K results require more careful consideration. Ultra at 105.3 FPS is playable but leaves little headroom for frame time spikes. High at 128.1 FPS provides a more comfortable margin, while Medium at 144.1 FPS is ideal for 144Hz 4K displays. Low at 159.3 FPS offers the best performance but sacrifices visual fidelity. Given Roblox's art style, the visual difference between Low and High is often minimal, making High or Medium the recommended presets for 4K gaming.

Across all resolutions, the data indicates that the Medium preset offers the best balance of performance and visual quality. At 1080p, Medium produces 381.3 FPS, at 1440p it yields 255 FPS, and at 4K it maintains 144.1 FPS. These numbers are high enough to satisfy any refresh rate requirement while providing a reasonable level of graphical detail. The Ultra preset is only recommended for users with 1080p displays, where the performance penalty is irrelevant. For 1440p and 4K, High or Medium are the sensible choices based on the measured data.
