Roblox

Roblox is a notoriously CPU-bound sandbox title, and pairing the 10-core Intel Core i5-13400F with the massive NVIDIA GeForce RTX 4080 SUPER produces a fascinating bottleneck dynamic. The benchmark data reveals a system capable of extraordinarily high frame rates—reaching 641.1 FPS at 1080p Low—but the performance scaling suggests the processor is doing the heavy lifting in this specific environment. While the GPU sits in the 88th percentile of all tested graphics cards, the measured results show that even at 4K Ultra, the combination never drops below 159.5 FPS, indicating that the RTX 4080 SUPER's immense 16 GB memory pool and 52.22 TFLOPS compute capacity are rarely stressed to their limits.

CPU Role

The Intel Core i5-13400F's architecture is central to understanding Roblox's performance profile. With 10 cores and 16 threads operating at a base clock of 2.50 GHz and a boost clock of 4.60 GHz, the processor provides substantial multi-threaded headroom. The benchmark data shows a Cinebench R23 multi-core score of 21,279, which is 7 times higher than the single-core score of 3,004, indicating that the CPU has significant parallel processing capability for a game engine that often relies on physics and script execution. The 20 MB of shared L3 cache and 1.25 MB per-core L2 cache help maintain low latency access to frequently used game data.

The processor's performance percentile of 82nd among all CPUs suggests it is a strong contender, but the data reveals something more interesting: the delta between the i5-13400F and its nearest rivals is remarkably small. The AMD EPYC 9474F, a server-class chip, scores only 0.5% higher, while the AMD Ryzen 5 5600X3D scores 0.5% lower. This tight clustering implies that in Roblox, the CPU's raw compute power is less critical than other factors, likely memory latency and single-thread efficiency. The PassMark single-thread score of 3,634 and the 3DMark single-thread score of 960 both indicate strong per-core performance, which is essential for Roblox's primary game thread.

The data suggests that in this combination, the CPU is the primary driver of frame rates at lower resolutions. The 1080p Low result of 641.1 FPS far exceeds what the GPU alone would typically deliver, indicating the processor is pushing instructions rapidly without waiting on graphics rendering. However, the 65W TDP and "Active" production status confirm this is an efficient, mainstream part that can sustain high clocks without exotic cooling. The 3DMark max-thread score of 7,307 versus the 16-thread score of 7,314 shows negligible scaling beyond 16 threads, confirming that Roblox's engine does not benefit from additional logical processors beyond what this CPU provides.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is an enormous graphics processor on paper, but the measured FPS data reveals that Roblox rarely taps into its full potential. With 16 GB of GDDR6X memory on a 256-bit bus delivering 736.3 GB/s of bandwidth, the GPU has ample resources for texture streaming and draw calls. The Ada Lovelace architecture features 10,240 shading units and 80 RT cores, clocked at a boost speed of 2550 MHz, providing 52.22 TFLOPS of FP32 compute. The PassMark G3D score of 34,245 places it in the 88th percentile, yet the game's performance at 4K Ultra (159.5 FPS) suggests the GPU is not the limiting factor.

The comparison with the AMD Radeon RX 6900 XT is telling: the RTX 4080 SUPER's average benchmark score is only 0.2% higher, yet the architectural differences are substantial. The 320W TDP and 45,900 million transistors on a 379 mm² die indicate a high-power, high-performance part, but the game's modest graphics demands mean the GPU idles relative to its capabilities. The pixel rate of 285.6 GPixel/s and texture rate of 816.0 GTexel/s are massive, but Roblox's blocky aesthetic and simple shaders do not stress these units heavily.

The most revealing metric is the scaling between settings at 4K. Moving from Low (244.9 FPS) to Ultra (159.5 FPS) represents a 34.9% drop, which is significant but still leaves the GPU well above the refresh rates of most monitors. The 3DMark Steel Nomad DX12 score of 6,600 and Geekbench Vulkan score of 226,163 demonstrate the GPU's raw power, but the data implies that in this title, the RTX 4080 SUPER is effectively overkill. The GPU's role shifts from a performance bottleneck to a quality enabler, allowing maximum settings with headroom to spare.

Measured FPS Breakdown

The measured frame rates across resolutions and settings paint a clear picture of a system that is CPU-limited at 1080p and progressively becomes more balanced at 4K. At 1920x1080, the Low preset achieves 641.1 FPS, while Medium delivers 578.6 FPS, High drops to 514.5 FPS, and Ultra settles at 416 FPS. The drop from Low to Ultra is 35.1%, which is substantial but still leaves the system capable of driving high-refresh-rate displays. The data indicates that at 1080p, the CPU is the primary constraint, as the GPU's rendering time is negligible compared to the CPU's frame submission rate.

Moving to 2560x1440, the frame rates remain exceptionally high: Low at 426.3 FPS, Medium at 389.6 FPS, High at 341.6 FPS, and Ultra at 279.5 FPS. The percentage drop from Low to Ultra at this resolution is 34.4%, nearly identical to the 1080p scaling. This consistency suggests that the bottleneck is shifting but not yet fully GPU-bound. The 1440p results are particularly interesting because they show that even with 77.7% more pixels than 1080p, the frame rates only drop by 33.5% at Low settings, indicating that the GPU has ample headroom.

At 3840x2160, the system delivers 244.9 FPS on Low, 218.3 FPS on Medium, 194.4 FPS on High, and 159.5 FPS on Ultra. The scaling from Low to Ultra is 34.9%, which is remarkably consistent across all resolutions. The 4K results show that the GPU is finally becoming a meaningful contributor to performance, but even at the most demanding settings, the frame rate remains above 144 Hz. The average FPS values across all 12 measured configurations highlight that this combo never falls below the 159.5 FPS floor, making it suitable for any current display technology.

How This Combo Ranks

The combination of the Intel Core i5-13400F and NVIDIA GeForce RTX 4080 SUPER secures the 134th position out of 1,800 tested combos in Roblox, placing it in the top 7.4% of all systems. This ranking is notable because it places the combo ahead of many configurations that might feature more expensive or newer components. The data suggests that Roblox rewards balanced systems with strong single-thread performance and high memory bandwidth, rather than simply raw GPU compute power.

The CPU's nearest rival comparison shows that the i5-13400F is virtually indistinguishable from the AMD Ryzen 5 5600X3D in average score, differing by only 0.5%. This implies that the choice between Intel and AMD in this price segment has minimal impact on Roblox performance. The GPU's 88th percentile ranking and its 2.9% advantage over the RTX 5070 Ti suggest that the 4080 SUPER is near the top of the performance hierarchy, yet the combo rank of 134 indicates that other factors, such as memory configuration and driver optimization, play a significant role in the final FPS numbers.

The ranking also reveals that the combo is not primarily GPU-limited; if it were, the rank would likely be higher given the GPU's percentile. The fact that it ranks 134th out of 1,800 suggests that the CPU is the more significant factor in determining Roblox performance. This is corroborated by the measured FPS data, which shows diminishing returns from GPU upgrades at 1080p and 1440p, where the CPU's frame submission rate caps the achievable FPS.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target refresh rate. For 4K displays with a 144 Hz refresh rate, the High preset at 194.4 FPS provides a comfortable margin above the refresh limit while maintaining visual quality. The Ultra preset at 159.5 FPS still exceeds 144 Hz, but the performance difference between High and Ultra is only 17.9%, making Ultra a viable choice for those who prioritize image quality over a small FPS buffer.

For 1440p users with 240 Hz monitors, the High preset at 341.6 FPS is the best balance, as it provides over 100 FPS of headroom above the refresh rate. The Medium preset at 389.6 FPS offers more headroom but sacrifices visual fidelity, while Ultra at 279.5 FPS still exceeds 240 Hz. The data suggests that High is the sweet spot at this resolution, as the FPS difference between Medium and High is only 12.3%, but the visual improvement is likely noticeable.

At 1080p, the situation changes dramatically. For 360 Hz esports displays, the Low preset at 641.1 FPS is the only option that guarantees maximum frame rates, but the Medium preset at 578.6 FPS still provides over 200 FPS of headroom. The High preset at 514.5 FPS is suitable for 240 Hz displays, while Ultra at 416 FPS is best for 144 Hz monitors. The recommendation varies by use case, but the data clearly shows that this combo can handle any settings at 1080p without dropping below 416 FPS.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals the shifting bottleneck dynamic. At Low settings, the frame rate drops from 641.1 FPS at 1080p to 426.3 FPS at 1440p (a 33.5% reduction) and then to 244.9 FPS at 4K (a 42.5% reduction from 1440p). The scaling is not linear, indicating that the GPU load increases disproportionately at higher resolutions. This pattern suggests that at 1080p, the CPU is the primary limiter, while at 4K, the GPU begins to contribute more significantly to the performance equation.

At Ultra settings, the scaling is slightly different: 416 FPS at 1080p, 279.5 FPS at 1440p (a 32.8% drop), and 159.5 FPS at 4K (a 42.9% drop from 1440p). The consistency of the percentage drops across Low and Ultra settings—both around 33% from 1080p to 1440p and 42-43% from 1440p to 4K—indicates that the resolution scaling is independent of the graphics quality preset. This is a curious finding, as it suggests that Roblox's rendering pipeline has a fixed pixel-processing cost that scales predictably with resolution, regardless of the shading complexity.

The data implies that the RTX 4080 SUPER's 16 GB of VRAM is sufficient to hold all assets, even at 4K Ultra, as the frame rates do not show signs of memory bandwidth saturation. The 736.3 GB/s of memory bandwidth is likely more than adequate for Roblox's relatively simple textures and geometry. The resolution scaling analysis indicates that users moving from 1080p to 4K can expect roughly a 61.8% reduction in FPS at the same settings, which is a significant but manageable drop given the high starting point.
