Roblox

The Intel Core i5-11400F paired with the Intel Arc B580 delivers remarkably high frame rates in Roblox, a game known for its lightweight rendering demands. The measured data shows this combination consistently exceeds the refresh rates of most standard monitors, even at the demanding 4K resolution. The analysis below breaks down the specific performance metrics, optimal settings, and the distinct roles the CPU and GPU play in producing these results.

FAQ

Q: What is the overall performance rank of this CPU and GPU combination in Roblox?

A: The combination ranks 1404 out of 1800 tested combos, placing it in the lower-middle portion of the database for this specific game. This rank is somewhat surprising given the high absolute frame rates, but it reflects the fact that many other tested combos, likely with higher-tier CPUs, achieve even higher scores in this CPU-light title.

Q: How does the Intel Core i5-11400F compare to its nearest rivals in general benchmark scores?

A: The CPU’s average benchmark score is 17181. Its closest rival, the AMD Ryzen 7 5700U, scores 17189, representing a 0% delta. The Intel Core i7-1260P scores 17212, which is -0.2% relative to the i5-11400F, indicating the i5 is slightly faster than that rival. The Intel Core Ultra 7 164U also scores 17215, another -0.2% delta.

Q: What is the best frame rate achieved in 1080p, and at what settings?

A: The highest average frame rate measured is 295.6 FPS, achieved at 1920x1080 with Low settings. This represents the peak performance ceiling for this combo in the tested configurations.

Q: Does the Intel Arc B580 outperform the NVIDIA GeForce RTX 4060?

A: Based on average benchmark scores, the Intel Arc B580 has an average score of 23021. The NVIDIA GeForce RTX 4060 has an average score of 23181, which results in a deltaPct of -0.7% for the Arc B580. This indicates the RTX 4060 is slightly faster in general GPU benchmarks, but the performance difference is very small.

Q: What is the frame rate drop when moving from 1080p to 4K at High settings?

A: At 1920x1080 with High settings, the average frame rate is 237.3 FPS. At 3840x2160 with High settings, the average frame rate falls to 91.4 FPS. This represents a significant drop of 145.9 FPS, or roughly 61.5%, when moving to 4K.

Q: What is the GPU's memory bandwidth and clock speed?

A: The Intel Arc B580 features a memory clock of 2375 MHz with a 19 Gbps effective data rate. It has a memory bus width of 192 bit, which provides a total memory bandwidth of 456.0 GB/s.

Settings Recommendations

The measured FPS data clearly indicates that the most demanding "Ultra" preset is not necessary for a smooth experience and significantly impacts performance. At 2560x1440, the Ultra preset delivers 130 FPS, while the High preset provides 157.9 FPS, a 27.9 FPS improvement. The trend is even more pronounced at 3840x2160, where Ultra drops to 71.4 FPS, but High maintains a solid 91.4 FPS.

For the best balance between visual fidelity and performance, the High preset is the recommended choice. It provides a substantial visual upgrade over Low and Medium settings while retaining frame rates well above 90 FPS at 4K. At 1920x1080, High settings achieve 237.3 FPS, which is more than enough for any high-refresh-rate monitor. The Medium preset offers a slight performance bump over High but likely sacrifices visual quality for a marginal gain, making High the sweet spot for this combination.

The Low preset serves a specific purpose for competitive play, where maximizing frame rate is the priority. At 1080p, it pushes the average to 295.6 FPS, which could be beneficial for players with 240Hz displays. However, for most users, the visual compromises of Low are not worth the extra frames when High already provides a superior experience. The data suggests that Ultra is best avoided, as it incurs a performance penalty without a proportional improvement in experience compared to High.

GPU Role

The Intel Arc B580 plays the primary role in determining frame rates in Roblox, as evidenced by the significant performance scaling across resolutions. The GPU's 12 GB of GDDR6 memory on a 192-bit bus provides a bandwidth of 456.0 GB/s, which is more than sufficient for Roblox's texture and asset streaming at all tested settings. The memory clock operates at 2375 MHz, with a 19 Gbps effective rate.

The GPU's base and boost clocks are both 2670 MHz. The architecture is Xe2-HPG, built on a 5 nm process by TSMC, with 19,600 million transistors. The Arc B580's raw compute capabilities, rated at 13.67 TFLOPS for FP32, are far beyond what Roblox requires. This is why even at 4K High settings, the GPU still manages an average of 91.4 FPS.

However, the GPU's performance is not without limits. The benchmark results show a clear bottleneck emerging at higher resolutions. The drop from 102.4 FPS at 4K Medium to 71.4 FPS at 4K Ultra indicates that the increased shading and post-processing effects in the Ultra preset stress the GPU's 2560 shading units and 80 ROPs. The GPU's PassMark G3D score of 15748 and its 66th percentile ranking among all GPUs confirm it is a mid-range performer, yet it is clearly robust enough to handle Roblox's workload with ease.

Measured FPS Breakdown

The measured data provides a comprehensive look at performance across three resolutions and four quality presets. At 3840x2160, the average frame rates are 110.3 FPS for Low, 102.4 FPS for Medium, 91.4 FPS for High, and 71.4 FPS for Ultra. This shows a steady decline as settings are increased, with the most significant drop occurring between High and Ultra.

At 2560x1440, the performance is substantially higher. The Low preset achieves an average of 195.8 FPS, Medium reaches 179.8 FPS, High delivers 157.9 FPS, and Ultra still maintains a very playable 130 FPS. The scaling from 4K to 1440p shows an average improvement of roughly 75-85 FPS across all settings, demonstrating the GPU's headroom at this resolution.

At 1920x1080, the frame rates become exceptionally high, likely hitting the CPU or game engine's limit. The Low preset peaks at 295.6 FPS, Medium follows at 266.1 FPS, High achieves 237.3 FPS, and Ultra drops to 193.5 FPS. The gap between 1080p and 1440p results is smaller than the gap between 1440p and 4K, suggesting that at 1080p, the system is no longer purely GPU-limited and other factors are coming into play.

How This Combo Ranks

The Intel Core i5-11400F and Intel Arc B580 combination holds a rank of 1404 out of 1800 tested combos in Roblox. This places it in the 22nd percentile of all tested systems. Despite delivering over 90 FPS at 4K and nearly 300 FPS at 1080p, the rank is relatively low. This indicates that the database contains a large number of combinations, likely with more powerful CPUs, that achieve even higher frame rates in this specific title.

The low rank relative to the high absolute performance suggests that Roblox is highly sensitive to CPU performance for achieving the absolute maximum frame rates. While the Arc B580 provides ample GPU power, the i5-11400F's general performance, which ranks in the 75th percentile of all CPUs, may be the limiting factor in pushing frame rates beyond the 300 FPS threshold. The combo's position is a reminder that high absolute numbers do not always translate to a high ranking when a niche game favors particular hardware strengths.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor from the Rocket Lake architecture, built on Intel's 14 nm process. Its base clock is 2.60 GHz and it boosts up to 4.40 GHz. The CPU has a 12 MB shared L3 cache and 512 KB of L2 cache per core. It supports DDR4 memory in a dual-channel configuration, providing a memory bandwidth of 51.2 GB/s.

In Roblox, the CPU's role is to handle game logic, physics, and draw calls. The data suggests that while the GPU is the primary driver of frame rates at 4K, the CPU becomes increasingly relevant at lower resolutions. The i5-11400F's performance in CPU benchmarks, such as a Cinebench R23 multi-core score of 14372 and a single-core score of 2029, indicates it has solid processing power.

However, the frame rate scaling from 1440p to 1080p is less pronounced than from 4K to 1440p. For instance, at High settings, the jump from 4K to 1440p is 66.5 FPS, but the jump from 1440p to 1080p is only 79.4 FPS, which is a smaller relative increase. This hints that the CPU is beginning to throttle the frame rate at 1080p, preventing the full potential of the GPU from being realized. The CPU's PassMark single-thread score of 2981 and its rank in the 75th percentile of all CPUs suggest it is a capable processor, but it is not at the very top tier needed to feed the Arc B580 at extremely high frame rates in this particular game.
