Roblox

Roblox is a notoriously CPU-bound sandbox title, and the data for the Intel Core i5-14600KF paired with the NVIDIA GeForce RTX 4070 SUPER confirms this dynamic with unusual clarity. The measured frame rates across resolutions and settings reveal a system where the GPU is often idle, waiting on processor threads, yet the headroom available is so vast that the experience remains exceptionally fluid at every configuration tested.

Resolution Scaling

The frame rate scaling from 1080p to 4K follows a predictable pattern of decline, but the absolute numbers remain staggeringly high. At 1920x1080 with High settings, the combo produces 450 FPS, which drops to 302.1 FPS at 2560x1440, and further to 169.7 FPS at 3840x2160. This represents a 33% reduction from 1080p to 1440p, and a 62% reduction from 1080p to 4K. The scaling is steep, but the starting point is so elevated that even the 4K result is far beyond the refresh rate of typical high-end monitors.

The delta between Low and Ultra settings widens considerably as resolution increases. At 1080p, the spread between Low (560.7 FPS) and Ultra (367.3 FPS) is 193.4 FPS, a 34.5% performance penalty for maxing out visuals. At 4K, the same comparison shows Low at 209.7 FPS and Ultra at 135.6 FPS, a 74.1 FPS gap. This behavior indicates that at lower resolutions, the CPU is the primary bottleneck, and the GPU can render frames so quickly that the workload shifts entirely to processor logic; as pixel count rises, the GPU begins to take on more of the load, making the Ultra settings' additional shader and texture work more impactful.

The most telling data point is the 4K Low result of 209.7 FPS. This is a resolution that typically crushes mid-range GPUs, yet here it produces a triple-digit frame rate with minimal graphical fidelity. The RTX 4070 SUPER, with its 12 GB of GDDR6X memory and 504.2 GB/s bandwidth, is clearly not struggling with memory capacity or throughput at this resolution. The bottleneck is the game's engine and the CPU's ability to feed draw calls, not the graphics card's rasterization power. When the settings are lowered, the GPU has even less work to do, and the frame rate only climbs to 209.7 FPS, suggesting a hard ceiling imposed by the processor or the game's single-threaded physics and scripting.

GPU Role

The RTX 4070 SUPER is built on the Ada Lovelace architecture with a 5 nm process from TSMC, featuring 7,168 shading units and 56 RT cores. Its boost clock of 2475 MHz and base clock of 1980 MHz are high, but in Roblox, these specifications matter less than the card's raw geometry throughput. The GPU's 80 ROPs and 224 TMUs provide 198.0 GPixel/s and 554.4 GTexel/s of fill rate, which is more than sufficient for the blocky, low-poly aesthetics of Roblox.

The memory subsystem is equally robust: 12 GB of GDDR6X on a 192-bit bus yields 504.2 GB/s of bandwidth. This is a configuration designed for 1440p and 4K gaming in modern AAA titles, so it is massively overprovisioned for Roblox. The data supports this, as the frame rate difference between Medium and High settings at 1440p is only 39.2 FPS (341.3 vs 302.1), while the jump from High to Ultra costs 56.1 FPS. This non-linear scaling suggests that the Ultra preset introduces effects that stress the GPU's compute units more than memory bandwidth.

The GPU's percentile ranking of 84 versus all other graphics cards, and its average benchmark score of 42,576, place it in the upper echelon of consumer hardware. Its nearest rival, the NVIDIA RTX A6000, has an average score of 42,653, a delta of -0.2%, meaning the RTX 4070 SUPER is effectively tied with a workstation card. In Roblox, this compute headroom is largely irrelevant; the card is never the limiting factor. The passmark G3D score of 29,995 and DirectX 12 score of 110 confirm strong API performance, but the game's engine is likely utilizing DirectX 11 or lower, leaving the card's modern feature set, including DirectX 12 Ultimate, underutilized.

CPU Role

The Intel Core i5-14600KF is the dominant component in this pairing. With 14 cores and 20 threads, split between performance and efficiency cores, it offers a blend of high single-thread speed and substantial multi-thread capability. The base clock of 3.50 GHz and boost clock of 5.30 GHz are critical for Roblox, which relies heavily on a single primary thread for game logic and physics. The 24 MB of shared L3 cache and 2 MB per-core L2 cache reduce latency for frequently accessed data, which is essential for the game's scripting engine.

The CPU's benchmark results are stellar. Its Cinebench R23 single-core score of 4,643 and multi-core score of 32,889 indicate a processor that excels in both lightly-threaded and heavily-threaded workloads. The Geekbench single-core score of 2,778 and multi-core score of 15,636 reinforce this. The PassMark single-thread score of 4,273 is particularly relevant; this metric directly correlates with the kind of game logic processing Roblox demands. The CPU's percentile ranking of 93 versus all processors, with an average benchmark score of 49,367, places it near the top of the desktop stack.

Looking at the nearest rivals, the i5-14600KF is nearly identical to the Intel Core i5-14600K, with a delta of only 0.4% in average score. It also edges out the AMD Ryzen 9 5950X by 0.6%, a processor with many more cores but lower single-thread performance. This data shows that for Roblox, the 14600KF's high boost clock is more valuable than core count. The 125 W TDP and unlocked multiplier allow for overclocking, potentially pushing the boost clock even higher, but the stock performance is already sufficient to drive frame rates well beyond display capabilities.

How This Combo Ranks

In the database of 1,800 tested combinations for Roblox, this pairing of the i5-14600KF and RTX 4070 SUPER ranks at position 331. This places it in the top 18.4% of all configurations, which is a strong showing but not a top-tier result. The rank is likely held back by the CPU's position in the hierarchy; there are processors with even higher single-core scores, such as the top-end 14th Gen and 13th Gen i9 variants, that would rank higher. The RTX 4070 SUPER is not the limiting factor, as its performance is far beyond what Roblox requires.

The combo rank of 331 suggests that while this system is exceptionally fast, it is not the absolute peak for Roblox. A system with a faster CPU, such as a 14900KS, would likely shave off a few percentage points of frame time in CPU-bound scenarios. However, the 14600KF's 93rd percentile CPU ranking and the GPU's 84th percentile ranking create a balanced platform that excels in this specific title. The data indicates that the CPU is the primary driver of the rank, as the GPU's role is secondary.

Measured FPS Breakdown

At 1920x1080, the system is purely CPU-bound. Low settings produce 560.7 FPS, which is the highest result in the entire dataset. Medium settings reduce this to 505.3 FPS, High to 450 FPS, and Ultra to 367.3 FPS. The performance drop from Low to Ultra is 193.4 FPS, a 34.5% reduction. This shows that even at 1080p, the GPU is still capable of rendering the scene faster than the CPU can issue commands, so the frame rate is dictated by processor speed. The difference between Low and Medium is 55.4 FPS, while the difference between High and Ultra is 82.7 FPS, indicating that the Ultra preset adds significant shader complexity that slightly tips the balance toward GPU limitation.

Moving to 2560x1440, the frame rates remain astronomically high. Low settings deliver 373.4 FPS, Medium 341.3 FPS, High 302.1 FPS, and Ultra 246 FPS. The scaling is more linear than at 1080p, with a more consistent 30-40 FPS drop between each settings tier. This suggests that at 1440p, the GPU is beginning to take on a more significant portion of the workload, but it is still not the primary bottleneck. The 4K results at 3840x2160 show the most dramatic shift: Low produces 209.7 FPS, Medium 192.5 FPS, High 169.7 FPS, and Ultra 135.6 FPS. The drop from Low to Ultra is 74.1 FPS, a 35.3% reduction, which is the largest relative penalty in the dataset.

The overall pattern is clear: at every resolution, the system delivers playable, if not overkill, frame rates. The 4K Ultra result of 135.6 FPS is still far above the 60 FPS standard for console gaming, and the 1080p Low result of 560.7 FPS is suitable for the highest refresh rate monitors available. The data suggests that for competitive play, where frame rate is king, users should stick to 1080p or 1440p with High or Medium settings. For visual fidelity, 4K Ultra is viable, but the frame rate dips below the 144 Hz threshold that many high-end displays target. The RTX 4070 SUPER's 12 GB of memory and 504.2 GB/s bandwidth are never stressed, and the i5-14600KF's single-core performance is the linchpin that keeps Roblox running at speeds that most other games cannot approach.
