Roblox

Roblox with an Intel Core i5-11400F and NVIDIA GeForce RTX 3070 delivers exceptionally high frame rates across all tested settings, positioning this combination in the 844th spot out of 1800 tested combos. The data indicates that this system is heavily overqualified for the game’s typical graphical demands, with performance often limited by the CPU’s single-thread capabilities rather than the GPU’s output. The benchmark results show a system capable of pushing well beyond standard refresh rates, making it a strong candidate for high-refresh-rate monitors at 1080p and 1440p.

GPU Role

The NVIDIA GeForce RTX 3070, built on the Ampere architecture with 8 GB of GDDR6 memory on a 256-bit bus, provides a substantial 448.0 GB/s of memory bandwidth. This bandwidth is a key factor in the GPU's ability to handle Roblox's varied and often unoptimized rendering loads, ensuring that texture streaming and draw calls do not become bottlenecks. The GPU’s boost clock of 1725 MHz, combined with 5888 shading units, delivers enough raw compute power to produce the high frame rates seen in the measured data. Its 20.31 TFLOPS of FP32 performance allows it to process the game's geometry and lighting effects with ease, even when the CPU is feeding it data as fast as possible.

The data shows that the RTX 3070 is rarely the limiting factor in this pairing. Across all resolutions, the frame rate scales more dramatically with CPU-dependent settings than with resolution changes, suggesting that the GPU has ample headroom. The GPU’s performance percentile of 72, alongside its Passmark G3D score of 22214, confirms it is a high-tier component capable of far more demanding tasks. In this game, the GPU’s role is to handle the final rendering and post-processing, which it does without breaking a sweat, leaving the CPU as the primary constraint on maximum FPS.

Settings Recommendations

Analyzing the measured FPS rows, the most balanced experience is found at 2560x1440 with High settings, which delivers an average of 221.4 FPS. This resolution and setting combination provides a significant visual upgrade over 1080p while maintaining a frame rate well above the 144 Hz refresh rate common on modern monitors. At 1080p, the High preset yields 332.2 FPS, which is beneficial for competitive play, but the jump to 1440p offers a crisper image that many users prefer for a sandbox game like Roblox.

For users prioritizing the absolute smoothest gameplay on a 240 Hz or higher monitor, the 1920x1080 Medium preset at 378.2 FPS is a strong choice, offering a marginal visual reduction from High but with a substantial FPS boost. Conversely, the Ultra preset at 4K drops to 100.7 FPS, which is still playable but begins to approach the refresh rate limits of standard 60-100 Hz displays, making it less ideal for fast-paced action. The data suggests that High settings at 1440p or Medium at 1080p offer the best trade-off between image quality and the high frame rates this hardware is capable of producing.

How This Combo Ranks

This specific combination of the Intel Core i5-11400F and the NVIDIA GeForce RTX 3070 ranks 844th out of 1800 tested combos in Roblox. This places it in the upper-middle tier of all tested systems, which is notable given the game’s relatively low graphical demands compared to modern AAA titles. The ranking suggests that while the hardware is very capable, many other combinations, likely featuring more powerful CPUs, achieve higher frame rates due to Roblox’s CPU-bound nature.

The ranking implies that the bottleneck is the CPU, not the GPU. The i5-11400F’s single-thread score in Cinebench R23 is 2029, which is strong, but its performance places it in the 75th percentile of all CPUs, indicating that a significant portion of processors are faster. This means that while the RTX 3070 is drawing ahead in many systems, the i5-11400F holds the combo back from reaching the top 46% of results. The data confirms that for Roblox, a faster CPU would yield a higher rank than a faster GPU.

Resolution Scaling

The FPS drop from 1080p to 4K reveals important insights about the system’s limiting component. At 1080p Low, the combo achieves 411.5 FPS, while at 4K Low it drops to 156.4 FPS, a decrease of 255.1 FPS. This large drop indicates that at lower resolutions, the CPU is the primary bottleneck, as the GPU is capable of rendering frames far faster than the CPU can issue draw calls, leading to a plateau in performance.

Conversely, the drop from 1080p Ultra (267.7 FPS) to 4K Ultra (100.7 FPS) shows a reduction of 167 FPS, which is a smaller absolute drop but a more significant percentage decrease (62%). This suggests that as the resolution and graphical load increase, the GPU becomes more heavily utilized, and the system shifts from a CPU-bound state to a more balanced state. The data implies that at 4K, the RTX 3070’s 8 GB of VRAM and 448.0 GB/s bandwidth are sufficient, but the increased pixel count demands more from the GPU, reducing the CPU’s ability to limit the frame rate.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. The Low preset leads with an average of 411.5 FPS, followed by Medium at 378.2 FPS, High at 332.2 FPS, and Ultra at 267.7 FPS. These numbers show a consistent scaling pattern where each increase in settings reduces the frame rate by roughly 10-15%, reflecting the incremental load on the GPU.

Moving to 2560x1440, the frame rates remain high but drop accordingly. The Low preset averages 274.6 FPS, Medium achieves 251.8 FPS, High produces 221.4 FPS, and Ultra settles at 181 FPS. At 3840x2160, the system begins to show the GPU’s workload more clearly. Low settings yield 156.4 FPS, Medium drops to 143.1 FPS, High reaches 127.3 FPS, and Ultra falls to 100.7 FPS. The data highlights that even at 4K, the system stays above 100 FPS on the Ultra preset, which reflects the RTX 3070’s raw power.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor from the Rocket Lake architecture, running on a 14 nm process. Its base clock of 2.60 GHz and boost clock of 4.40 GHz are crucial for Roblox, which relies heavily on single-thread performance for game logic and physics. The CPU’s single-thread benchmark scores, such as the 3DMark single-thread score of 868 and the Cinebench R23 single-core score of 2029, indicate its capability in this regard, though it is not a top-tier performer.

The data suggests that the i5-11400F is the limiting factor in this combo, as evidenced by the relatively small FPS differences between Low and High settings at 1080p (411.5 vs 332.2 FPS). This indicates that the CPU is unable to feed the GPU enough data to fully utilize its potential at lower resolutions. However, at 4K, the FPS differences between settings become more pronounced, showing that the GPU is now the bottleneck. The CPU’s 12 MB of shared L3 cache and 51.2 GB/s memory bandwidth provide adequate support for the game’s data streaming, but its performance percentile of 75 versus the GPU’s 72 confirms that the CPU is the weaker link in this pairing.
