Roblox

Roblox is a demanding title in its own way, and the data for the Intel Core i5-11400F paired with the AMD Radeon RX 7700 reveals a combination that is heavily skewed toward high refresh rate gameplay. The measured frames per second (FPS) across all resolutions and settings are exceptionally high, indicating that this system will not struggle to run the game. The primary question is not whether the game is playable, but rather how much headroom exists for maximum visual quality versus maximum frame rate, and where the bottleneck shifts as you change resolution.

Resolution Scaling

The performance drop from 1080p to 4K is substantial, but the absolute numbers remain at playable levels throughout. At 1080p with Low settings, the combo delivers an average of 386 FPS. Moving to 1440p Low drops that to 258 FPS, a reduction of 33.2%. Stepping up to 4K Low yields 146 FPS, which is 43.4% lower than the 1440p figure and 62.2% lower than the 1080p result. This steep decline indicates that at lower resolutions, the Intel Core i5-11400F is likely the primary limiting factor, as the GPU has plenty of headroom to render frames quickly but is being held back by the CPU's ability to feed it draw calls.

The pattern shifts when examining higher settings. At Ultra settings, the average FPS goes from 252 at 1080p to 168 at 1440p (a 33.3% drop), and then to 95 at 4K (a 43.5% drop from 1440p). The consistent percentage drops across settings suggest that the scaling is primarily resolution-driven, which is typical. However, the gap between Low and Ultra at 4K is notable: 146 FPS versus 95 FPS. This 53.7% performance penalty for enabling Ultra settings at 4K shows that the Radeon RX 7700 is beginning to feel the load of higher pixel counts and more complex shaders. At 1080p, the difference between Low (386 FPS) and Ultra (252 FPS) is a 53.2% drop as well, showing the GPU is still working hard even at lower resolutions when pushed to maximum quality.

The data shows that the system is most balanced at 1440p, where the FPS range of 168 (Ultra) to 258 (Low) provides a wide spectrum of choices. At 1080p, the frame rates are so high that the CPU is almost certainly the bottleneck, as the GPU cannot fully stretch its legs due to the processor's single-thread performance limits. At 4K, the GPU becomes the limiting factor, especially at Medium and Ultra settings where the pixel fill rate and shading requirements dominate. The min FPS data points available (113 at 4K Medium, 199 at 1440p Medium, 299 at 1080p Medium) show that even the lowest measured frames are well above the 60 FPS threshold for smooth gameplay, suggesting a consistent experience without major hitches.

FAQ

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor based on the Rocket Lake architecture, with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. Its benchmark scores show a significant gap between single-thread and multi-thread performance. The Cinebench R23 single-core score is 2024, while the multi-core score is 14340, indicating a 7.1x scaling, which is typical for a 6-core part. The 3DMark scores are also revealing: the single-thread score is 868, while the max-thread score is 5652, showing that the processor scales well with additional threads.

In Roblox, which is known to be heavily reliant on single-thread performance for its physics and world simulation, the i5-11400F's single-core capabilities are crucial. The PassMark single-thread score of 2981 is a strong indicator of how the CPU handles the game's primary thread. The data shows that at 1080p Low settings, the system achieves 386 FPS, which is likely near the CPU's limit for this game. The fact that increasing the resolution from 1080p to 1440p Low only drops the FPS from 386 to 258 (a 33.2% reduction) while the pixel count increases by 77.8% suggests that the CPU is indeed the limiting factor at lower resolutions, as the GPU is not being fully utilized.

The processor's 12 MB of shared L3 cache and 51.2 GB/s memory bandwidth are sufficient for feeding the GPU at high frame rates, but the data indicates that the CPU's instruction throughput is the bottleneck at 1080p. The boost clock of 4.40 GHz is critical for this scenario, as Roblox's main thread benefits from higher IPC and clock speeds. The 3DMark 2-thread score of 1691 is particularly relevant, as it shows the processor's capability when only two threads are heavily loaded, which is often the case in Roblox's update loop. The CPU's percentile ranking of 71 against all CPUs further confirms that it is a competent performer, but not a top-tier part, which aligns with its role as the limiting factor in the highest-FPS scenarios.

How This Combo Ranks

The Intel Core i5-11400F and AMD Radeon RX 7700 combination holds the 1341st position out of 3010 tested combos for Roblox. This placement in the 55.4th percentile means that this system outperforms a majority of the other configurations in the database. However, it is not near the top, suggesting that there are many other combos that deliver higher frame rates, likely with more powerful CPUs or GPUs.

The combo's ranking is influenced by the CPU's performance ceiling in this specific game. The i5-11400F's nearest rivals in the CPU benchmark database include the AMD EPYC 7H12 (0.3% faster), the Intel Core i5-12450H (0.4% slower), and the AMD Ryzen 3 PRO 8300G (0.6% slower). These are all within a 1% margin, indicating that the i5-11400F sits in a tightly packed performance tier. The GPU's nearest rivals are the AMD Radeon R9 370X (0.1% slower), the AMD Radeon RX 9060 (1% faster), and the NVIDIA GeForce RTX 3060 Ti (1.7% faster). The RX 7700 is also in a close performance band.

Given that the CPU and GPU are both mid-pack performers relative to their respective competitors, the combined ranking of 1341 reflects a balanced but not extreme system. The data shows that the combo is capable of producing very high frame rates, but the ranking suggests that other combos with stronger CPUs or GPUs can push even higher. The fact that the combo ranks in the top 55% is notable, but it is not a top-10% performer. This is consistent with the CPU being the bottleneck at lower resolutions, which prevents the system from reaching the absolute highest frame rates seen in the database.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. The Low preset averages 386 FPS, which is the maximum measured across all configurations. The Medium preset averages 352 FPS with a min of 299 and a max of 404. The High preset averages 311 FPS, and the Ultra preset averages 252 FPS. The progression from Low to Ultra shows a clear cost for visual quality, with a 34.7% drop from Low to High and a 53.2% drop from Low to Ultra.

At 2560x1440, the frame rates remain extremely high. The Low preset averages 258 FPS, which is 33.2% lower than the 1080p Low result. The Medium preset averages 235 FPS with a min of 199 and a max of 270. The High preset averages 207 FPS, and the Ultra preset averages 168 FPS. The drop from Low to Ultra at this resolution is 53.6%, nearly identical to the 1080p drop, indicating that the GPU is scaling its workload consistently.

At 3840x2160, the system still delivers smooth performance. The Low preset averages 146 FPS, which is 43.4% lower than the 1440p Low result. The Medium preset averages 133 FPS with a min of 113 and a max of 153. The High preset averages 117 FPS, and the Ultra preset averages 95 FPS. The drop from Low to Ultra at 4K is 53.7%, showing that the GPU's rendering cost scales linearly with the resolution and settings.

The data across all resolutions shows that the Medium preset provides a good balance of frame rate and visual quality, with min FPS values that are still very high. At 1080p Medium, the min of 299 FPS is above the refresh rate of most high-end monitors. At 1440p Medium, the min of 199 FPS is still above 144 Hz, and at 4K Medium, the min of 113 FPS is above 100 Hz. This suggests that the Medium preset is a safe choice for maintaining a high refresh rate experience at any resolution.

Settings Recommendations

Based on the measured data, the Medium preset is the most versatile choice for this combo across all resolutions. At 1080p, the Medium preset achieves an average of 352 FPS with a min of 299, which is more than enough for any display. At 1440p, the Medium preset delivers 235 FPS with a min of 199, which is ideal for 144 Hz monitors. At 4K, the Medium preset averages 133 FPS with a min of 113, which is suitable for high-refresh-rate 4K displays that support 120 Hz or higher.

For users with a 1080p monitor that has a 240 Hz or 360 Hz refresh rate, the High preset is a better option. It delivers 311 FPS, which is close to the max refresh rate of 360 Hz displays, and it offers better visual fidelity than Low or Medium. The Ultra preset at 1080p still provides 252 FPS, which is above 240 Hz, but the performance cost over High is 19% (311 to 252 FPS), which may not be worth the visual gains for competitive play.

For 1440p users with a 144 Hz monitor, the High preset is the sweet spot, delivering 207 FPS with headroom to spare. The Ultra preset at 168 FPS is also viable for 144 Hz displays, but it offers diminishing returns over High. At 4K, the High preset at 117 FPS is the best choice for a 120 Hz display, providing a smooth experience without the 23.2% performance penalty of Ultra (95 FPS). The Low preset at 4K is only recommended for users who prioritize maximum frame rates over visual quality, as it does not offer a significant advantage over Medium for most use cases.

The data clearly shows that this combo is capable of handling Roblox at any resolution with high settings, and the choice of preset should be dictated by the refresh rate of the display and the user's preference for visual fidelity over raw FPS. The Medium preset is the safest recommendation for a balanced experience, while High is recommended for those with high-refresh-rate displays who want to push visual quality without sacrificing performance.
