Roblox

Roblox is unusually forgiving on high-end hardware, and the benchmark data for the Intel Core i5-10400F paired with the NVIDIA GeForce RTX 4080 SUPER confirms this. The combo achieves a 4K Ultra average of 155.6 FPS and a 1080p Low average of 582.5 FPS, placing it at rank 154 out of 1800 tested combinations. The data indicates that while the RTX 4080 SUPER is massively overpowered for this title, the Core i5-10400F is sufficient to feed it at every resolution tested. This pairing is less about GPU headroom and more about CPU-driven frame pacing, as the performance gaps between settings presets narrow significantly at lower resolutions.

FAQ

Q: What is the highest average frame rate recorded for this combo in Roblox?

A: The highest recorded average is 582.5 FPS at 1920x1080 with Low settings. This is the absolute ceiling for the combo in the measured data.

Q: How does the CPU compare to its nearest rival in synthetic benchmarks?

A: The Intel Core i5-10400F has an average benchmark score of 14168. Its closest rival, the AMD EPYC 7552, scores 14115, making the i5-10400F 0.4% faster. It also leads the AMD Ryzen 3 7320C by 0.8% and the Intel Core i5-8500 by 1.1%.

A: No. At 1080p Ultra, the combo produces 416.8 FPS, while at 1080p Low it produces 582.5 FPS. The 165.7 FPS difference suggests the CPU is the primary limiter at this resolution, as the GPU is not fully saturated.

Q: What is the GPU's percentile ranking among all tested GPUs?

A: The NVIDIA GeForce RTX 4080 SUPER falls in the 88th percentile of all GPUs. Its average benchmark score is 53610, which is 0.2% higher than the AMD Radeon RX 6900 XT (53489).

Q: How much performance is lost when moving from 1080p to 4K on High settings?

A: The average frame rate drops from 514.6 FPS at 1080p to 194.3 FPS at 4K. This represents a 62.2% reduction in average FPS, indicating a significant shift in load onto the GPU.

Q: Does the CPU have enough threads for this game?

A: The i5-10400F has 6 cores and 12 threads. Given that the 1080p Low result (582.5 FPS) is only slightly higher than the 1440p Low result (424.8 FPS), the CPU is likely the bottleneck, but its 12 threads are sufficient to maintain high frame rates without collapsing.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the dominant component in this pairing, built on the Ada Lovelace architecture with a 5 nm process. Its 16 GB of GDDR6X memory on a 256-bit bus provides 736.3 GB/s of bandwidth, which is far beyond what a sandbox game like Roblox typically requires. The GPU's base clock is 2295 MHz, boosting to 2550 MHz, and it houses 10240 shading units. Benchmark results show its strength: it scores 34245 in Passmark G3D and 6600 in 3DMark Steel Nomad DX12, placing it in the 88th percentile of all GPUs.

In this specific game, the GPU's role becomes almost trivial at lower resolutions. The data shows that at 1080p Low, the combo hits 582.5 FPS, but at 1080p Ultra, it still manages 416.8 FPS. The 165.7 FPS gap between these settings is relatively small in percentage terms (about 28.5% faster on Low), which suggests that the GPU is not being pushed to its limits. Instead, the frame rate is being capped by the CPU's ability to process the game's logic and draw calls. At 4K, the GPU finally becomes the primary driver: the Ultra preset drops to 155.6 FPS, while the Low preset reaches 240.2 FPS. This 84.6 FPS gap is larger, showing that the 4080 SUPER is now doing more work per frame, but it still never approaches a performance wall.

The GPU's 52.22 TFLOPS of FP32 performance and 816.0 GTexel/s texture rate are overkill for Roblox's visual fidelity. The measured data indicates that even at 4K Ultra, the combo is far from struggling, as 155.6 FPS is well above the refresh rate of most monitors. The RTX 4080 SUPER's capabilities are effectively held in reserve; the game simply does not demand the full 320 W TDP that the card is rated for.

Resolution Scaling

The frame rate scaling across resolutions reveals a classic CPU-bound scenario at lower settings. Moving from 1080p to 1440p on Low settings, the average FPS drops from 582.5 to 424.8, a 27.1% decrease. This is a substantial drop, but it is not proportional to the pixel count increase (which is about 77.8% more pixels). The modest drop indicates that the CPU is still the primary bottleneck, and the GPU has ample headroom to handle the extra pixel load.

However, when moving from 1440p to 4K on Low settings, the average FPS falls from 424.8 to 240.2, a 43.5% decrease. This larger drop signals that the GPU is beginning to take on more responsibility. The trend is more pronounced on the Ultra preset: 1080p to 1440p yields a drop from 416.8 to 279.6 (32.9% decrease), and 1440p to 4K yields a drop from 279.6 to 155.6 (44.3% decrease). The data clearly shows that the scaling becomes more GPU-bound as resolution increases.

What this means for the limiting component is nuanced. At 1080p, the CPU is the clear bottleneck, as the GPU could likely produce even higher frame rates if the CPU could keep up. At 4K, the GPU becomes the limiting factor, but the CPU is still not completely off the hook. The fact that the 4K Ultra score (155.6 FPS) is still very high suggests that even in the most demanding scenario, the i5-10400F can maintain a playable frame rate without holding the RTX 4080 SUPER back too severely.

Measured FPS Breakdown

At 1920x1080, the combo produces its highest frame rates. The Low preset yields an average of 582.5 FPS, while Medium comes in at 561.9 FPS. High settings drop to 514.6 FPS, and Ultra is the slowest at 416.8 FPS. The gap between Low and Ultra is 165.7 FPS, showing that the CPU is the limiting factor here, as the GPU is not struggling with the load.

Moving to 2560x1440, the frame rates remain exceptionally high. Low settings produce 424.8 FPS, Medium drops to 386.0 FPS, and High yields 342.1 FPS. Ultra is the most demanding, with an average of 279.6 FPS. The delta between Low and Ultra here is 145.2 FPS, which is smaller than at 1080p, indicating that the GPU is starting to contribute more to the performance equation.

At 3840x2160, the GPU is fully engaged. Low settings deliver 240.2 FPS, Medium drops to 219.4 FPS, and High falls to 194.3 FPS. Ultra is the slowest preset, with an average of 155.6 FPS. The difference between Low and Ultra is 84.6 FPS, which is the smallest absolute gap across all resolutions. This suggests that at 4K, the GPU is the primary bottleneck, as the performance difference between settings presets shrinks when the GPU is saturated.

How This Combo Ranks

The combo ranks 154th out of 1800 tested combinations in Roblox. This places it in the top 8.6% of all tested systems, which is a strong showing for a CPU that is not the newest generation. The ranking is likely driven by the RTX 4080 SUPER's raw power, but the i5-10400F does not drag it down significantly.

In terms of CPU performance, the i5-10400F has an average benchmark score of 14168, placing it in the 73rd percentile of all CPUs. Its nearest rival, the AMD EPYC 7552, scores 14115, which is 0.4% lower. The Intel Core i5-8500 scores 14332, which is 1.1% higher than the i5-10400F. This means the CPU is competitive with older server and desktop parts, but it is not a top-tier contender.

For the GPU, the RTX 4080 SUPER scores 53610 on average, placing it in the 88th percentile. Its nearest rival, the AMD Radeon RX 6900 XT, scores 53489, which is 0.2% lower. The NVIDIA GeForce RTX 5070 Ti scores 52086, which is 2.9% lower. This indicates that the GPU is near the top of its class, and its high percentile rank is a major factor in the combo's overall rank of 154.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. At 1920x1080, even the Ultra preset achieves 416.8 FPS, which is more than enough for any high-refresh-rate monitor. There is no reason to lower settings below High at this resolution, as the 514.6 FPS on High is already far beyond what most displays can show.

At 2560x1440, the Ultra preset still delivers 279.6 FPS, which is excellent. The High preset at 342.1 FPS offers a slight bump, but the visual quality difference is likely minimal. For most users, High or Ultra at 1440p is the best balance, as the frame rates are so high that the CPU becomes the limiting factor, not the GPU.

At 3840x2160, the Ultra preset drops to 155.6 FPS, which is still very smooth. However, the High preset at 194.3 FPS offers a noticeable improvement in frame rate without a massive visual penalty. For users with a 4K 144Hz monitor, the High preset is the recommended choice, as it stays above 144 FPS on average. The Medium preset at 219.4 FPS is also viable if frame rate is prioritized over visual fidelity. The Low preset at 240.2 FPS is only useful for competitive play where every frame matters, but the visual downgrade is severe.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor based on the Comet Lake architecture, manufactured on a 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.30 GHz, with 12 MB of shared L3 cache. Its synthetic benchmark scores are modest: it scores 10297 in Cinebench R23 multi-core and 1453 in single-core. These numbers place it in the 73rd percentile of all CPUs, which is respectable but not exceptional.

In Roblox, the CPU's role is critical because the game is often CPU-bound at lower resolutions. The data supports this: at 1080p Low, the combo hits 582.5 FPS, but at 1440p Low, it drops to 424.8 FPS. This 157.7 FPS drop is not proportional to the pixel increase, which suggests that the CPU is struggling to keep up with the game's logic at higher frame rates. The i5-10400F's 4.30 GHz boost clock and 12 threads are sufficient to maintain high frame rates, but they are the limiting factor in this pairing.

The CPU's memory bandwidth of 42.7 GB/s and DDR4 support are adequate for this game. The 3DMark scores show that the CPU scales well with threads: it scores 1350 in the 2-thread test and 4748 in the 16-thread test. This indicates that the CPU can handle multi-threaded workloads, which is beneficial for Roblox's physics and scripting. However, the single-thread score of 688 in 3DMark is relatively low, which could be a bottleneck in a game that relies heavily on single-threaded performance. Overall, the i5-10400F is a capable CPU for Roblox, but it is the weaker link in this combo compared to the RTX 4080 SUPER.
