# How This Combo Ranks

The Intel Core i5-13400F paired with the NVIDIA GeForce RTX 5070 Ti ranks 165th out of 1,800 tested combos in Roblox. This places the configuration in the top 9.2% of all tested systems, a strong result that reflects the hardware's ability to push very high frame rates in this title. The ranking is particularly notable because Roblox is a game where CPU performance often dominates, and the i5-13400F's 10 cores and 16 threads provide a solid foundation.

When examining the CPU's synthetic benchmark averages, the i5-13400F sits at 25,236, which is nearly identical to the Intel Core i7-13620H's 25,201, a delta of just 0.1%. The AMD Ryzen 5 5600X3D posts a slightly higher 25,365, putting the i5-13400F 0.5% behind that chip. The i5-13400F also edges out the AMD EPYC 9474F and AMD Ryzen AI 5 PRO 340, both at 25,103 and 25,099 respectively, with a 0.5% advantage. This clustering indicates the CPU is performing at a level where small differences in synthetic scores do not translate into meaningful gameplay disparities.

On the GPU side, the RTX 5070 Ti achieves an average benchmark score of 52,086, placing it at the 87th percentile of all GPUs. Its nearest rival, the RTX 4080, scores 52,085, a delta of 0.0%, meaning the two cards are effectively tied in raw compute. The AMD Radeon RX 7700S is 0.8% ahead at 52,505, while the AMD Radeon Pro W6600M leads by 2.5% with 53,414. The NVIDIA RTX A1000 trails by 2.5% at 50,826. These margins are small, yet the measured FPS in Roblox shows this combo achieving frame rates far beyond what the synthetic scores would suggest, pointing to the game's specific optimization patterns.

# GPU Role

The RTX 5070 Ti brings substantial memory resources to Roblox, with 16 GB of GDDR7 on a 256-bit bus delivering 896.0 GB/s of bandwidth. This is far more than the game requires, as Roblox's blocky aesthetic and relatively simple geometry do not stress memory capacity or bandwidth. The GPU's memory clock runs at 1750 MHz, translating to 28 Gbps effective, which contributes to the high bandwidth figure.

The GPU's base clock is 2295 MHz with a boost of 2452 MHz, and it contains 8,960 shading units alongside 280 TMUs and 96 ROPs. The 70 RT cores and 280 tensor cores provide additional compute resources, though Roblox's rendering pipeline does not heavily utilize ray tracing or AI acceleration. The card's FP32 throughput of 43.94 TFLOPS is substantial, but in Roblox, the GPU often operates below its full potential because the CPU becomes the limiting factor at lower resolutions.

Looking at the measured FPS data, the GPU's role becomes clearer as resolution increases. At 1080p Low, the combo hits 618 FPS, but at 4K Ultra, it drops to 152.8 FPS. This scaling shows that the GPU is not the bottleneck at 1080p, where frame rates exceed 600, but it begins to matter more at 4K. The transition from 1440p High (327.3 FPS) to 4K High (187.7 FPS) represents a 42.7% drop, indicating that the GPU's workload is scaling significantly with resolution. The RTX 5070 Ti's position at the 87th percentile of all GPUs, with a PassMark G3D score of 32,974, confirms it is a high-end part, yet Roblox's engine still manages to leverage it effectively at higher resolutions.

# CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on the Raptor Lake architecture, built on Intel's 10 nm process. It has a base clock of 2.50 GHz and a boost clock of 4.60 GHz, with a 65 W TDP. The CPU supports both DDR4 and DDR5 memory in dual-channel mode, and its 20 MB shared L3 cache is substantial for a mid-range desktop part. The 80 KB L1 cache per core and 1.25 MB L2 cache per core provide fast access to frequently used data.

In Roblox, the CPU's role is amplified because the game's physics and scripting are often single-threaded or lightly threaded. The i5-13400F's single-thread performance is strong, with a 3DMark single-thread score of 960 and a Cinebench R23 single-core score of 3,004. Multi-threaded performance is also robust, with a Cinebench R23 multi-core score of 21,279 and a Geekbench multi-core score of 10,971. The CPU's PassMark single-thread score of 3,634 is particularly relevant for Roblox, where high clock speeds and efficient instruction handling matter more than raw core counts.

The measured FPS data shows the CPU's influence most clearly at 1080p. At 1080p Low, the combo reaches 618 FPS, which is likely near the game's engine limit. Moving from 1080p Low to 1080p Ultra (401.8 FPS) shows a 35% drop, but the absolute frame rates remain very high. At 1440p, the CPU still holds sway, with Low setting producing 409.3 FPS. The CPU's percentile ranking at 82% of all CPUs, with an average benchmark score of 25,236, puts it slightly ahead of the i7-13620H by 0.1%, confirming it is a capable performer for this workload. The 3DMark 16-thread score of 7,314 and max-thread score of 7,307 indicate that the CPU's performance scales well with additional threads, even if Roblox does not always utilize them.

# Resolution Scaling

The measured FPS data reveals how the balance of CPU and GPU load shifts across resolutions. At 1080p Low, the combo achieves 618 FPS, which drops to 492.5 FPS at High and 401.8 FPS at Ultra. The difference between Low and Ultra at 1080p is 216.2 FPS, or 35%. At 1440p, the Low setting produces 409.3 FPS, while Ultra yields 268.1 FPS, a difference of 141.2 FPS or 34.5%. At 4K, Low reaches 236 FPS, and Ultra drops to 152.8 FPS, a difference of 83.2 FPS or 35.3%.

The percentage drop from 1080p to 4K is consistent across settings. For Low, the drop from 618 FPS to 236 FPS represents a 61.8% reduction. For High, the drop from 492.5 FPS to 187.7 FPS is 61.9%. Medium falls from 559.1 FPS to 212.7 FPS, a 62% reduction, and Ultra drops from 401.8 FPS to 152.8 FPS, a 62% reduction. This uniformity suggests that the scaling is primarily driven by the GPU, as the relative performance hit is consistent regardless of settings.

However, the absolute frame rates tell a different story. Even at 4K Ultra, the combo maintains 152.8 FPS, which is well above the refresh rate of most monitors. At 1080p, the frame rates exceed 400 FPS even at Ultra, indicating that the CPU is the primary limiter at this resolution. The i5-13400F's 10 cores and 16 threads are sufficient to feed the GPU at 1080p, but the engine's single-threaded nature means it cannot reach the 618 FPS Low ceiling with more demanding settings. At 4K, the GPU's workload increases, and the RTX 5070 Ti's 8,960 shading units begin to matter more, but the CPU still keeps up with the demand.

# Settings Recommendations

The measured data shows that the Low preset at 1080p delivers 618 FPS, which is the highest recorded value in the entire dataset. However, this comes at the cost of visual fidelity. The Medium preset at 1080p produces 559.1 FPS, only 9.5% lower than Low, while providing better visual quality. The High preset at 1080p yields 492.5 FPS, which is still exceptionally high and offers a more polished visual experience.

At 1440p, the Medium preset achieves 372.3 FPS, which is a reasonable compromise between visual quality and performance. The High preset at 1440p drops to 327.3 FPS, a 12.1% reduction from Medium, but still well above any practical refresh rate. The Ultra preset at 1440p produces 268.1 FPS, which remains playable and visually rich.

For 4K, the Medium preset at 212.7 FPS is the best balance, as it maintains a high frame rate while providing better visuals than Low. The High preset at 187.7 FPS is also viable, and Ultra at 152.8 FPS is acceptable for those prioritizing visual quality over raw speed. The data indicates that the Medium preset offers the most consistent experience across all resolutions, with frame rates ranging from 212.7 FPS at 4K to 559.1 FPS at 1080p. Given that even the Ultra preset exceeds 150 FPS at 4K, users can confidently select higher settings without sacrificing playability. The Low preset is recommended only for competitive play where maximum frame rates are desired, as the difference between Low and Medium is minimal in absolute terms but noticeable in visual quality.
