FAQ

Q: What is the best resolution for this combo in Roblox?

A: The data shows the combo excels at 1920x1080, where it averages 367.8 FPS on Low settings and 299 FPS on High settings. At 2560x1440, it still delivers strong results, with a 199.6 FPS average on High settings. While it can handle 4K, the averages drop to between 91.9 FPS (Ultra) and 141.6 FPS (Low).

Q: How does the RX 6700 XT compare to its nearest rivals?

A: The RX 6700 XT has an average benchmark score of 33721, sitting in the 77th percentile of all GPUs. It is nearly identical in performance to the AMD Radeon RX 6800, which has a deltaPct of 0.7. It also edges out the NVIDIA RTX A5000 by a margin of 1.3%.

Q: Is the Core i5-11400F a bottleneck for the RX 6700 XT in Roblox?

A: At 1080p and 1440p, the CPU appears sufficient. The measured FPS scales significantly with resolution, which points toward the GPU becoming the primary limiting factor at higher resolutions. The i5-11400F’s 6 cores and 12 threads, with a boost clock of 4.40 GHz, provide enough processing power to keep up with the GPU’s output in this title.

Q: What is the difference in FPS between Low and Ultra settings at 1440p?

A: The difference is substantial. At 2560x1440, the Low preset averages 246.8 FPS, while the Ultra preset averages 161 FPS. This represents a performance drop of about 35% when moving from Low to Ultra, showing that the Ultra preset is significantly more demanding.

Q: How much of a performance gain is seen from moving from 4K to 1440p?

A: The gain is very large. On High settings, moving from 3840x2160 (114.2 FPS) to 2560x1440 (199.6 FPS) yields an increase of 85.4 FPS. This clearly indicates that the GPU is heavily taxed at 4K resolution.

Q: Where does this combo rank for Roblox performance?

A: The data places this specific CPU and GPU combination at rank 971 out of 1800 tested combos for Roblox. While this is just past the halfway point, the measured frame rates are high enough for smooth gameplay on high-refresh-rate monitors.

GPU Role

The AMD Radeon RX 6700 XT is the driving force behind the high frame rates seen in Roblox. Its benchmark results show strong compute capabilities, with a PassMark G3D score of 19786 and a Geekbench OpenCL score of 100730. The card’s 12 GB of GDDR6 memory on a 192-bit bus provides a bandwidth of 384.0 GB/s, which is adequate for the texture and asset loads in a sandbox game like Roblox, even at higher resolutions. The GPU’s boost clock of 2581 MHz and game clock of 2424 MHz are relatively high, contributing to its raw throughput.

The data reveals that the GPU’s performance is a clear differentiator. When the resolution increases, the frame rate drops consistently, which is a classic sign of GPU-bound performance. For instance, at High settings, the average FPS drops from 299 at 1080p to 199.6 at 1440p, and further to 114.2 at 4K. This scaling indicates that the RX 6700 XT is the primary component being stressed as pixel count rises. Its position in the 77th percentile of all GPUs, with an average benchmark score of 33721, confirms it’s a strong performer that can handle the graphical demands of Roblox with ease, especially at mainstream resolutions. The card’s performance is closely matched with the AMD Radeon RX 6800, showing it is near the top of its class for this game's requirements.

CPU Role

The Intel Core i5-11400F provides the foundation for the system, and its role in Roblox is to feed the GPU with data. It has 6 cores and 12 threads, with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. This is a modern Rocket Lake architecture on a 14 nm process. In CPU-bound scenarios, which are common in sandbox games with complex physics and logic, this processor’s performance is critical. Its Cinebench R23 multi-core score of 14372 and single-core score of 2029 indicate a balanced processor that can handle both multi-threaded workloads and single-threaded game engine tasks.

The benchmark data suggests that at 1080p, the CPU is still able to keep up. The average FPS of 367.8 on Low settings shows that the CPU is not limiting the frame rate, as the GPU is still able to render frames quickly. However, the processor’s performance is a key factor in preventing frame drops in busy scenes. The i5-11400F’s 12 MB of shared L3 cache helps with quick data access. Its nearest rivals, such as the AMD Ryzen 7 5700U, have nearly identical average benchmark scores, with a deltaPct of 0. This means the i5-11400F is on par with other mid-range competitors, ensuring it won't be the weak link in this pairing. The data shows that the CPU is not the bottleneck at 1440p and 4K, as the FPS drops are more closely tied to the GPU's workload.

Measured FPS Breakdown

The measured data provides a comprehensive view of the combo's performance across resolutions and settings. At 1920x1080, the combo is incredibly fast, with the Low preset hitting an average of 367.8 FPS. The Medium preset averages 338 FPS, and High averages 299 FPS. Even the most demanding Ultra preset manages an average of 240.7 FPS, which is well above the refresh rate of most monitors.

Moving to 2560x1440, the performance remains strong but shows the GPU starting to work harder. The Low preset averages 246.8 FPS, Medium drops to 221.8 FPS, and High averages 199.6 FPS. The Ultra preset still maintains a high average of 161 FPS, which is excellent for 1440p gaming.

At 3840x2160, the GPU is clearly the limiting factor. The Low preset averages 141.6 FPS, which is still playable. The Medium preset drops to 127.9 FPS, and High averages 114.2 FPS. The Ultra preset is the most demanding, with an average of 91.9 FPS. These numbers show that while 4K is possible, it requires a compromise on settings to achieve higher frame rates.

Resolution Scaling

The performance scaling from 1080p to 4K reveals a clear pattern of GPU-bound behavior. On High settings, the average FPS drops from 299 at 1080p to 199.6 at 1440p, a decrease of 99.4 FPS. Moving from 1440p to 4K, the average drops further from 199.6 to 114.2 FPS, another decrease of 85.4 FPS. This linear decline is a strong indicator that the RX 6700 XT is the component being saturated.

This scaling behavior has practical implications. At 1080p, the CPU and GPU are both working to produce very high frame rates. At 1440p, the GPU is being taxed more, but the system still delivers a premium experience. At 4K, the GPU is clearly the bottleneck, as the frame rates drop significantly. This suggests that for users with a 1080p or 1440p monitor, this combo will provide a very smooth experience. For 4K users, the data suggests that lower settings are necessary to maintain high refresh rates. The frame rate drop is not linear in percentage terms, but the trend is consistent: higher resolutions put more strain on the GPU.

Settings Recommendations

Based on the measured FPS, the optimal settings depend on your monitor’s refresh rate. For users with a high-refresh-rate 1080p monitor (240Hz or higher), the Low preset is ideal, delivering an average of 367.8 FPS. This ensures the frame rate stays well above the refresh rate, maximizing responsiveness. The High preset is also a great choice for 1080p, still averaging 299 FPS.

For 1440p users, the High preset is the sweet spot, offering an average of 199.6 FPS. This balances visual quality with performance, easily supporting a 144Hz or even a 165Hz monitor. The Ultra preset at 1440p also works well, with an average of 161 FPS, which is still suitable for high-refresh-rate displays.

At 4K, the choice is more about prioritization. The Medium preset, averaging 127.9 FPS, is a good balance for a 120Hz display. The Low preset, at 141.6 FPS, offers the highest frame rate at this resolution. The Ultra preset, while visually impressive, drops to 91.9 FPS, which is best suited for a 60Hz monitor. Given the data, for the best overall experience on a typical high-refresh-rate monitor, using the High preset at 1440p or the Low preset at 1080p will yield the most fluid and responsive gameplay in Roblox.
