Roblox

The Intel Core i5-11400F paired with the NVIDIA GeForce RTX 4070 SUPER delivers exceptional performance in Roblox, with the data showing a clear pattern of the CPU becoming the limiting factor at lower resolutions and the GPU taking over at 4K. This combo ranks in the top 17.5% of all tested configurations in this game, making it a formidable pairing for this sandbox title.

Resolution Scaling

The frame rate scaling across resolutions in Roblox reveals a system that is heavily CPU-bound at 1080p and becomes progressively GPU-bound as resolution increases. At 1080p with High settings, the combo produces an average of 450 FPS. At 1440p, that number drops to 300 FPS, and at 4K it settles at 170 FPS. This represents a 60% reduction from 1080p to 1440p and a 62% reduction from 1440p to 4K, demonstrating a steep curve that points to the GPU becoming the primary constraint at higher pixel counts.

The Low settings data confirms this trend even more strongly. At 1080p Low, the system hits 560 FPS, which is a massive 41% higher than the 4K High result of 170 FPS. The jump from 1080p Low to 4K Low is from 560 FPS to 211 FPS, a 62% decrease that is far more pronounced than what the resolution change alone would suggest if the CPU were the only bottleneck. This indicates that at 1080p, the i5-11400F with its 6 cores and 12 threads is maxing out what the game can feed the GPU, while at 4K, the RTX 4070 SUPER with 7168 shading units and 80 ROPs is doing the heavy lifting.

The Medium settings row is the only one with min and max FPS data, which provides a useful window into the frame time consistency. At 1080p Medium, the average is 509 FPS with a minimum of 433 and maximum of 586. At 4K Medium, the average drops to 192 FPS with a minimum of 163 and maximum of 221. The 4K result shows a narrower spread, which indicates that when the GPU becomes the bottleneck, frame pacing is more stable. The 1080p Medium spread of 153 FPS between min and max suggests that the CPU is being asked to feed the GPU at a rate that produces more frame-time variance.

This is a classic case of a CPU that is too strong for the game's engine at low resolutions. Roblox is not a graphically intense game, so the CPU becomes the limiting factor at 1080p. The data shows that dropping the resolution from 4K to 1080p at High settings yields a 165% increase in FPS (from 170 to 450), which is a far larger jump than the 4x pixel count would suggest. The RTX 4070 SUPER is clearly capable of far more than the CPU can feed it at lower resolutions.

FAQ

Q: What is the maximum refresh rate this combo can achieve at 1080p?

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor from the Rocket Lake architecture, with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. It has a 12 MB L3 cache and supports DDR4 memory with dual-channel bandwidth of 51.2 GB/s. This CPU is not unlocked, but that is not the primary factor in Roblox. The game is not particularly demanding on the CPU in terms of raw thread count, and the data supports this.

The benchmark results show that this CPU sits at the 71st percentile of all CPUs tested, with an average benchmark score of 17177. Its nearest rivals in terms of average score include the AMD EPYC 7H12 (score 17120, 0.3% slower) and the Intel Core i5-12450H (score 17239, 0.4% faster). This places the i5-11400F in a solid mid-tier position, but for Roblox the single-thread performance is more important than the multi-thread.

The single-thread benchmark scores are telling: a 3DMark single-thread score of 868, a Cinebench R20 single-core score of 850, and a Cinebench R23 single-core score of 2024. This is the kind of performance that allows the CPU to maintain high frame times in Roblox's physics and game logic. The multi-thread scores, such as the Cinebench R20 multi-core score of 6022 and the Cinebench R23 multi-core score of 14340, are not particularly relevant for Roblox because the game does not scale well across 12 threads.

The 4K data shows that the CPU is not the bottleneck at that resolution. At 4K High, the average is 170 FPS, and the GPU is the limiting factor. At 1080p, the situation is reversed: the CPU's single-thread performance is what keeps the average from reaching the 560 FPS mark on Low settings. The 6 cores and 12 threads are enough to avoid a multi-threaded bottleneck, but the 4.40 GHz boost clock is what allows the game to run at such high frame rates.

The CPU's performance in the Cinebench R23 multi-core test (14340) is a good indicator of its capability. This is a mid-range score that is sufficient for Roblox, but the game is not a CPU stress test. The data shows that at 1080p Low, the system still averages 560 FPS, which reflects the CPU's ability to keep up with the GPU. The bottleneck only becomes apparent when comparing the 1080p Low result (560 FPS) to the 1080p Ultra result (365 FPS), which shows a 35% reduction in performance, which is more than the GPU settings change would suggest.

How This Combo Ranks

In the database of tested combos for Roblox, this configuration ranks 651 out of 3711 total combinations. This is a strong ranking, placing it in the top 17.5% of all tested systems. The ranking is a measure of the combo's ability to run the game at high frame rates across a range of resolutions, and it reflects the combination of the i5-11400F and RTX 4070 SUPER.

The ranking is not the highest, but the data indicates that this is a very capable pairing for Roblox. The performance is high enough that it would be considered a top-tier result, with the only limiting factor being the CPU's single-thread performance at lower resolutions. The combo is not in the top 10% of all combos, but it is well above the median.

The ranking of 651 out of 3711 means there are 650 combos that perform better, but the majority of those are likely using higher-end CPUs with higher clocks or GPUs with more than 25% of the performance. The i5-11400F is a mid-range CPU, and the RTX 4070 SUPER is a high-end GPU, so the pairing is a balance of cost and performance, but the data shows it is a high-performing balance.

Measured FPS Breakdown

The measured data covers 12 rows across three resolutions and four settings (Low, Medium, High, Ultra). The results are as follows:

3840x2160 (4K)

• Low: 211 FPS average
• Medium: 192 FPS average, 163 min, 221 max
• High: 170 FPS average
• Ultra: 138 FPS average

2560x1440

• Low: 374 FPS average
• Medium: 340 FPS average, 289 min, 391 max
• High: 300 FPS average
• Ultra: 244 FPS average

1920x1080

• Low: 560 FPS average
• Medium: 509 FPS average, 433 min, 586 max
• High: 450 FPS average
• Ultra: 365 FPS average

The 1080p Medium preset is the only one with a full min/max range, showing a minimum of 433 FPS and a maximum of 586 FPS. This is a 153 FPS spread, which is a clear sign that even at Medium settings the system is pushing very high frame rates. The 4K Medium has a spread of 58 FPS (163 to 221), which is a more consistent result due to the GPU being the bottleneck.

The 1440p results show a similar pattern. The Low preset averages 374 FPS, the Medium averages 340, the High averages 300, and the Ultra averages 244. The 1440p Medium has a spread of 102 FPS (min 289, max 391), which is larger than the 4K Medium spread but still shows that the system is capable of producing frame rates well above 240 FPS for most presets.

The 1080p results are the most extreme. The Low preset averages 560 FPS, which is a very high result that only the best CPUs can achieve. The Medium preset averages 509, the High averages 450, and the Ultra averages 365. The Ultra preset is the only one at 1080p that falls below the 400 FPS threshold, but it still remains above the 300 FPS mark.

The data shows that the RTX 4070 SUPER is vastly underutilized at 1080p for this game. The 560 FPS on Low is more than the game engine can push, and the GPU is not the limitation. At 4K, the GPU becomes the bottleneck, with the Ultra preset dropping to 138 FPS, which is still a playable frame rate but shows the where the GPU limit is.

Settings Recommendations

For the best experience per the measured rows, the data suggests that the 1440p Medium preset is the most optimal. It offers a 340 FPS average with a minimum of 289 FPS, which is a frame rate that is high enough for any current 360 Hz monitor, and the frame pacing is stable. The 1080p Medium preset (509 FPS) is also a valid choice, but the frame rate is so high that the CPU is the limiting factor and the GPU is not being fully utilized.

For 4K gaming, the Medium preset (192 FPS) is the best balance between fidelity and performance. The High preset (170 FPS) is a step down, and the Ultra preset (138 FPS) is the most demanding, but the High preset is a better choice if you want to maintain a high refresh rate. The 4K Medium is a better choice than the 4K High if you want a higher refresh rate, but the 4K High is better if you want better visual quality.

The 1080p Ultra preset (365 FPS) is not recommended because the GPU is not the bottleneck, and the visual quality improvement is minimal. The 1440p High preset (300 FPS) is a very good choice for a 300 Hz monitor, but the 1440p Medium is a better choice for the same monitor with a higher refresh rate.

The data shows that the RTX 4070 SUPER is a powerful card, but the i5-11400F is not too slow for this game. The best experience is at 1440p Medium, where the system is not bottlenecked by the CPU and the GPU is fully utilized. The 4K Medium preset is also a solid choice for 4K displays, but it will not hit the high refresh rates that the 1440p Medium can.
