Roblox

The Intel Core i5-13400F and NVIDIA GeForce RTX 3060 Ti combination delivers exceptionally high frame rates in Roblox, consistently exceeding 90 FPS even under the most demanding settings tested. The data shows this pairing is overwhelmingly GPU-limited at lower resolutions, with the CPU's capability becoming relevant only when frame rates climb into the 300s at 1080p.

Resolution Scaling

The performance drop from 1080p to 4K reveals a clear progression where the graphics card becomes the primary bottleneck. At 1080p with Low settings, the combo produces 378 FPS. Moving to 1440p at the same settings reduces that to 253 FPS, a decline of 33%. At 4K, the Low preset averages 143 FPS, which is 62% below the 1080p figure. This steep scaling curve indicates that the RTX 3060 Ti is being pushed progressively harder as pixel count rises, while the i5-13400F has ample headroom to feed the GPU at every resolution tested.

The gap between Low and Ultra settings widens significantly at higher resolutions. At 1080p, the difference between Low (378 FPS) and Ultra (247 FPS) is 131 FPS. At 1440p, that spread narrows to 88 FPS (253 vs 165). At 4K, the difference contracts further to 50 FPS (143 vs 93). This pattern suggests that at 4K, the GPU's rasterization work dominates the frame time budget, making preset selection less impactful in absolute terms. However, the relative penalty of Ultra versus Low becomes more pronounced at 4K—Ultra delivers 65% of Low's frame rate, while at 1080p it delivers 65% as well, showing a consistent proportional cost.

The Medium preset provides the only complete data set with min and max FPS values. At 1080p Medium, the range spans from 293 to 396 FPS, while at 1440p it drops to 195–264 FPS, and at 4K it falls to 110–149 FPS. The minimum FPS values show that even in demanding scenes, the combo never dips below 110 FPS at any resolution with Medium settings. This suggests that Roblox's sandbox environments, while variable in complexity, do not present a sustained challenge to this hardware pairing.

How This Combo Ranks

The combination ranks 1825th out of 3711 tested combos for Roblox, placing it in the top half of all systems evaluated. This percentile position reflects the reality that Roblox is not a graphically demanding title, so even mid-range hardware like the RTX 3060 Ti can achieve high frame rates. The ranking also indicates that many other combinations—likely those with newer or higher-end GPUs—can push even higher FPS numbers, particularly at 1080p where the CPU becomes more relevant.

Within the context of the CPU's overall performance, the i5-13400F sits at the 77th percentile among all CPUs tested, with an average benchmark score of 25,292. Its nearest rival, the AMD Ryzen 9 6900HS, scores 25,284—essentially identical. The Intel Core 5 120 and AMD Ryzen 5 5600X3D are also within 0.3% of the i5-13400F's score. This tight clustering means that swapping the CPU for any of these alternatives would produce no measurable difference in Roblox performance, as they all deliver comparable processing capability.

The RTX 3060 Ti's GPU percentile is lower at 59, with an average score of 16,129. Its nearest rival, the AMD Radeon Pro 5600M, scores 16,351, which is 1.4% higher, while the AMD Radeon RX 5700 XT also sits 1.4% ahead. The AMD Radeon RX 9060 trails by 0.7% with a score of 16,014. These small deltas suggest that the 3060 Ti is well-matched against its contemporaries, though it is not a standout performer relative to the broader GPU pool.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest performance. Low settings produce an average of 378 FPS, while Medium achieves 344 FPS with a measured range of 293 to 396 FPS. High settings reduce the average to 304 FPS, and Ultra drops further to 247 FPS. The scaling from Low to Ultra represents a 35% performance penalty, which is modest given the visual quality improvements typically associated with higher presets.

Moving to 2560x1440, the frame rates remain high but show a clear step down. Low settings average 253 FPS, which is 33% lower than the 1080p Low figure. Medium settings reach 230 FPS with a range of 195 to 264 FPS. High settings produce 203 FPS, while Ultra averages 165 FPS. The gap between Low and Ultra at 1440p is 88 FPS, a 35% reduction from Low to Ultra.

At 3840x2160, the RTX 3060 Ti's limits become apparent. Low settings average 143 FPS, which is still highly playable but represents a 62% drop from 1080p Low. Medium settings achieve 130 FPS with a minimum of 110 and maximum of 149 FPS. High settings average 115 FPS, and Ultra drops to 93 FPS. At 4K, the Ultra preset is the only configuration that falls below 100 FPS, though 93 FPS remains smooth for Roblox's gameplay style.

The Medium preset is the only setting with complete min/max data across all resolutions, providing insight into frame time consistency. At 1080p, the range from 293 to 396 FPS indicates a variance of 103 FPS. At 1440p, the range narrows to 69 FPS (195–264). At 4K, the range tightens to 39 FPS (110–149). This pattern suggests that frame pacing becomes more consistent as the GPU becomes the bottleneck, reducing CPU-related hitches.

CPU Role

The Intel Core i5-13400F features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. For Roblox, which rarely utilizes more than a few threads, the single-core performance is paramount. The CPU's Cinebench R23 single-core score of 3,191 and Geekbench single-core score of 1,996 indicate strong per-thread capability, which supports the high frame rates observed at 1080p.

The CPU's 20 MB of shared L3 cache and 1.25 MB L2 per core provide low-latency access to frequently used data, which is beneficial for Roblox's physics and scripting workloads. The PassMark single-thread score of 3,634 aligns with the CPU's 77th percentile ranking, confirming that it outpaces a majority of tested processors in single-threaded tasks.

At 1080p with Low settings, the combo reaches 378 FPS, which is likely near the engine's or CPU's practical limit for Roblox. The i5-13400F's 3DMark single-thread score of 960 and 2-thread score of 1,880 suggest that even with two active threads, the CPU can sustain high instruction throughput. However, the scaling from 1080p to 1440p (a 33% drop) and 4K (a 62% drop) indicates that the GPU, not the CPU, dictates performance at higher resolutions.

The CPU's 65 W TDP and 10 nm process node mean it can sustain boost clocks without thermal throttling in most desktop configurations, ensuring consistent frame delivery. The PassMark physics score of 1,437 is modest, but Roblox's physics simulation is generally not heavy enough to stress this metric. Overall, the i5-13400F provides more than enough computational headroom for Roblox, with the GPU acting as the primary limiter above 1080p.

Settings Recommendations

For players targeting the highest possible frame rates on a high-refresh-rate 1080p monitor, the Low preset delivers 378 FPS, which maximizes responsiveness. However, the Medium preset at 344 FPS offers a better balance, with a measured minimum of 293 FPS that ensures no perceptible stutter. Given the small 34 FPS difference between Low and Medium, Medium is the better choice for most users, as it provides improved visual fidelity while staying well above 240 FPS.

At 1440p, the Medium preset is the recommended choice. It averages 230 FPS with a minimum of 195 FPS, which comfortably exceeds the 144 Hz refresh rate of most 1440p monitors. The High preset at 203 FPS is also viable, but the Medium preset's min/max data (195–264 FPS) suggests better frame pacing. The Ultra preset at 165 FPS remains playable, but the 65 FPS penalty versus Medium is substantial without a proportional visual gain.

For 4K gaming, the Medium preset provides the best experience. It averages 130 FPS with a minimum of 110 FPS, which is smooth on a 120 Hz 4K display. The High preset at 115 FPS is close, but the Medium preset's documented minimum of 110 FPS offers more headroom for demanding scenes. The Ultra preset at 93 FPS is the only setting that dips below 100 FPS, and while it may be acceptable for Roblox's blocky aesthetic, the 30% performance loss versus Medium is not justified.

The data suggests that Medium is the optimal preset across all resolutions, as it is the only setting with complete min/max data, indicating that the benchmark captured its full range of performance. The consistent pattern—Medium always falling between Low and High in frame rate—makes it a predictable choice. Players seeking maximum visual quality should use Ultra only at 1080p, where 247 FPS remains high, but at higher resolutions, the Medium preset's combination of speed and stability makes it the clear recommendation.
