Roblox

Roblox is a massively popular sandbox title that scales across a wide range of hardware, but benchmark data for the Intel Core i5-13400F and NVIDIA GeForce RTX 3070 Ti combination reveals a system that is dramatically overqualified for the game’s typical demands. The measured results show an exceptionally high-performance pairing, with frame rates that far exceed the refresh rates of most displays, even at demanding 4K resolutions. This analysis examines the CPU and GPU roles, the scaling of performance across settings and resolutions, and how this combo ranks against other tested configurations, all based strictly on the provided data.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-13400F is a 10-core, 16-thread processor based on the Raptor Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. In synthetic benchmarks, it scores 3,004 points in Cinebench R23 single-core and 21,279 points in multi-core, placing it in the 82nd percentile among all tested CPUs. The processor’s 20 MB of shared L3 cache and support for both DDR4 and DDR5 memory indicate a balanced design that excels in both lightly-threaded and heavily-threaded workloads.

For a game like Roblox, which is often described as CPU-bound due to its single-threaded game logic and physics, the i5-13400F’s single-core strength is critical. The data indicates that at 1080p with Low settings, the combo achieves 435.2 FPS. This exceptionally high frame rate is a direct result of the CPU’s ability to feed the GPU quickly, as the rendering load is relatively low. However, the game’s engine does not always scale perfectly with high core counts. While the 10-core configuration is future-proof and handles background tasks with ease, the 3dmark_2_threads score of 1,880 and the single-thread score of 960 suggest that the performance ceiling in Roblox is heavily influenced by the strength of a single core. The processor’s 4.60 GHz boost clock is likely the primary driver for achieving such high frame rates in this title.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution and refresh rate. At 1080p, even the most demanding preset, Ultra, yields an average of 284.3 FPS, which is far beyond the capability of most standard monitors. For players with high-refresh-rate displays (e.g., 240 Hz or 360 Hz), the Medium preset at 397.1 FPS or the High preset at 352.1 FPS would be excellent choices, providing a significant performance buffer. The Low preset at 435.2 FPS is the absolute maximum, but it may reduce visual fidelity for no practical benefit at this resolution.

At 1440p, the Ultra preset drops to 192.7 FPS, which is still very high, but the High preset at 232.5 FPS offers a better balance for 240 Hz displays. For a more consistent experience on a 144 Hz monitor, the Ultra settings at 192.7 FPS are perfectly playable and provide the best visual quality. At 4K, the situation changes. The Ultra preset yields 106.9 FPS, which is still above the 60 FPS threshold and suitable for high-refresh 4K displays, but the High preset at 130.1 FPS offers a noticeable improvement in smoothness without a major visual compromise. The data suggests that the High preset is the sweet spot for 4K, as it provides a 21.7% higher frame rate than Ultra while likely maintaining most visual effects. The Low preset at 4K (163.1 FPS) is an outlier, suggesting that the CPU is not a bottleneck even at this resolution, and the GPU is still able to push a very high number of frames.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The frame rate scaling from 1080p to 4K reveals a classic shift from a CPU-bound to a GPU-bound scenario. At 1080p High, the system averages 352.1 FPS. Moving to 1440p High, the frame rate drops to 232.5 FPS, a reduction of approximately 34%. At 4K High, the average is 130.1 FPS, which is a further 44% drop from the 1440p result. This steep decline as resolution increases indicates that the GPU becomes the primary limiting factor at higher pixel counts.

This is expected, as the rendering workload at 4K is roughly four times that of 1080p. The RTX 3070 Ti, with its 8 GB of GDDR6X memory and 608.3 GB/s of bandwidth, is still able to maintain high performance, but the data shows that the CPU is not the bottleneck at 4K. For instance, the difference between Low and High settings at 1080p is 83.1 FPS, while at 4K, the difference is only 33.0 FPS. This compression of the performance gap at higher resolutions is a classic sign of the GPU becoming the limiting component. The i5-13400F can deliver the frames at 1080p, but the GPU’s fill rate and pixel throughput, rated at 169.9 GPixel/s, are what ultimately cap performance at 4K.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of the Intel Core i5-13400F and NVIDIA GeForce RTX 3070 Ti ranks 724th out of 1,800 tested combos in Roblox. This places it in the top 40% of all systems, which is a strong showing given the enormous variety of hardware configurations tested. The rank suggests that while this combo is very powerful, there are many other systems that can achieve even higher frame rates in Roblox, likely due to even more powerful CPUs or GPUs.

The CPU itself is competitive with its nearest rivals. The i5-13400F has an average benchmark score of 25,236, which is 0.1% higher than the Intel Core i7-13620H and 0.5% higher than both the AMD EPYC 9474F and the AMD Ryzen AI 5 PRO 340. Interestingly, it is 0.5% lower than the AMD Ryzen 5 5600X3D. This indicates that the CPU is well-matched with its peers in overall processing power, but its specific ranking in Roblox is influenced by the game’s engine and the GPU pairing. The GPU also performs well relative to its peers, with an average benchmark score of 30,849, which is 0.3% higher than the AMD Radeon RX 590 GME and 0.8% higher than the AMD Radeon RX 6700. The combo rank of 724 indicates that the pairing is synergistic, but the data shows that Roblox is a title where top-tier single-threaded CPU performance and high GPU memory bandwidth are more important than raw multi-core throughput.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3070 Ti is based on the Ampere architecture and features 8 GB of GDDR6X memory on a 256-bit bus, delivering a bandwidth of 608.3 GB/s. Its base clock is 1575 MHz with a boost clock of 1770 MHz. The GPU’s 6,144 shading units and 96 ROPs are responsible for its high rasterization performance, which is reflected in its Passmark G3D score of 23,356 and a percentile rank of 74 among all GPUs.

In Roblox, the GPU’s role becomes more pronounced at higher resolutions and settings. At 4K Ultra, the GPU is the clear bottleneck, as the frame rate drops to 106.9 FPS. The 8 GB of VRAM is sufficient for Roblox, as the game does not typically require large texture pools, but the memory bandwidth is crucial for maintaining high frame rates. The GPU’s 21.75 TFLOPS of FP32 compute power ensures that it can handle the game’s shaders and lighting effects with ease, even at 4K. The data shows that the GPU is not heavily taxed at 1080p, where it is likely waiting for the CPU to provide draw calls. However, at 4K, the pixel rate of 169.9 GPixel/s and texture rate of 339.8 GTexel/s become the determining factors for performance. The significant frame rate differences between Low and Ultra settings at 4K (163.1 FPS vs. 106.9 FPS) are a direct consequence of the GPU’s workload increasing with visual complexity.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The complete set of measured average FPS data is as follows:

• 3840x2160 (4K): The Ultra preset averages 106.9 FPS. The High preset averages 130.1 FPS. The Medium preset averages 148.3 FPS. The Low preset averages 163.1 FPS.
• 2560x1440 (1440p): The Ultra preset averages 192.7 FPS. The High preset averages 232.5 FPS. The Medium preset averages 263.8 FPS. The Low preset averages 288.7 FPS.
• 1920x1080 (1080p): The Ultra preset averages 284.3 FPS. The High preset averages 352.1 FPS. The Medium preset averages 397.1 FPS. The Low preset averages 435.2 FPS.

The data shows a clear and consistent pattern. At each resolution, the Low preset provides the highest frame rate, and the Ultra preset provides the lowest. The most significant performance jump comes from moving from Ultra to High, while the difference between Medium and Low is smaller. For example, at 1440p, the difference between Ultra and High is 39.8 FPS, while the difference between Medium and Low is 24.9 FPS. This suggests that the Ultra preset introduces a disproportionately heavy performance cost for the visual improvements it offers. Across all settings, the scaling from 1080p to 4K is consistent, with the frame rate dropping by roughly half at each step up in resolution, reinforcing the GPU-bound nature of the game at higher pixel counts.
