Roblox

Roblox is not a typical triple-A stress test, but the measured data for the Intel Core i5-13400F and AMD Radeon RX 6700 XT combo shows it is capable of extremely high frame rates across all resolutions. The results place this pairing in the 52nd percentile of tested combos for this game, with a rank of 1940 out of 3711. The data indicates that the primary bottleneck shifts from the CPU at 1080p to the GPU as resolution increases, though the overall experience remains smooth even at 4K.

Settings Recommendations

For players prioritizing the highest possible frame rates on a high-refresh-rate 1080p monitor, the Low preset delivers the best measured performance. The data shows an average of 368 FPS at 1920x1080, which is 33 FPS higher than the next fastest preset and leaves substantial headroom above the 240 FPS Ultra setting. This preset is ideal for competitive scenarios where responsiveness and frame pacing matter more than visual fidelity.

The Medium preset at 1080p is the best balance for most users. It produces an average of 335 FPS with a minimum of 285 FPS and a maximum of 386 FPS. The minimum frame rate is notably higher than the Low preset's unspecified minimum, suggesting better frame stability. Given that the jump from Medium to High only costs 39 FPS on average (335 to 296), and the difference between High and Ultra is 56 FPS (296 to 240), Medium offers the most consistent experience without sacrificing the visual upgrades that Roblox's modern lighting systems provide.

At 2560x1440, the High preset is the recommended choice. It delivers an average of 198 FPS, which remains well above the 144 Hz refresh rate common on 1440p monitors. The Ultra preset drops to 160 FPS, which is still playable but begins to approach the threshold where frame drops become noticeable on higher refresh displays. The Low preset at 246 FPS is excessive for most 1440p displays and sacrifices too much visual quality for a marginal gain over High.

For 4K (3840x2160), the Medium preset is the sweet spot. It yields an average of 127 FPS with a minimum of 108 FPS and a maximum of 146 FPS. The High preset at 112 FPS is close, but the Medium preset's minimum frame rate of 108 FPS ensures the experience stays above the 100 FPS mark, which is preferable for maintaining smooth motion on displays that support variable refresh rates. The Ultra preset at 91 FPS is the only measured setting that dips below 100 FPS, making it less ideal for 4K gaming despite the visual improvements.

The data suggests that the Medium preset is the most versatile across all resolutions. It provides the only complete FPS dataset (with min and max values) in the measured results, indicating it is the most stable setting tested by the benchmark harness. This preset scales from 335 FPS at 1080p to 224 FPS at 1440p and 127 FPS at 4K, maintaining a playable frame rate at every resolution.

How This Combo Ranks

The combo ranks 1940 out of 3711 tested combinations in Roblox, placing it in the lower half of the database. This ranking might seem surprising given the high raw FPS numbers, but it reflects the fact that Roblox is a lightweight title where many lower-end or older components can also achieve high frame rates. The percentile ranking is more indicative of how this specific CPU-GPU pairing compares to other pairings tested in this specific game's workload.

The Intel Core i5-13400F itself sits in the 77th percentile of all CPUs tested. Its average benchmark score of 25,292 puts it nearly identical to the AMD Ryzen 9 6900HS (25,284, 0% delta), and slightly ahead of the AMD Ryzen 7 6800H (25,201, 0.4% delta). It trails the Intel Core 5 120 (25,362, -0.3% delta) and AMD Ryzen 5 5600X3D (25,365, -0.3% delta) by a negligible margin. This CPU is clearly capable of driving high frame rates in Roblox, as evidenced by the 368 FPS result at Low settings 1080p.

The AMD Radeon RX 6700 XT ranks in the 72nd percentile of all GPUs. Its average benchmark score of 27,425 is essentially tied with the NVIDIA GeForce RTX 4070 Mobile (27,435, 0% delta), slightly ahead of the NVIDIA GeForce RTX 3090 (27,565, -0.5% delta), and behind the AMD Radeon Pro Vega 20 (27,839, -1.5% delta). The GPU's performance in Roblox is more than sufficient, but the game's simplicity means that the GPU is often underutilized, particularly at lower resolutions.

The combination of a high-percentile CPU and GPU does not translate to a high combo rank because Roblox's engine is not particularly demanding on either component. The 52nd percentile rank suggests that many other combinations—likely including older or cheaper parts—can achieve similar or better results in this specific title. The data shows that the limiting factor in Roblox is often the game engine itself, not the hardware.

Measured FPS Breakdown

At 1920x1080, the results show a clear progression across settings. The Low preset achieves an average of 368 FPS, which is the highest measured result for this resolution. The Medium preset follows at 335 FPS (minimum 285, maximum 386), the High preset at 296 FPS, and the Ultra preset at 240 FPS. The difference between Low and Ultra is 128 FPS, representing a 53% reduction in frame rate when maxing out the visual settings.

At 2560x1440, the frame rates remain high but the scaling pattern changes. The Low preset averages 246 FPS, the Medium preset averages 224 FPS (minimum 190, maximum 257), the High preset averages 198 FPS, and the Ultra preset averages 160 FPS. The drop from Low to Ultra is 86 FPS, or 35%, which is a smaller relative penalty than at 1080p.

At 3840x2160, the GPU begins to show its limits. The Low preset averages 139 FPS, the Medium preset averages 127 FPS (minimum 108, maximum 146), the High preset averages 112 FPS, and the Ultra preset averages 91 FPS. The Ultra preset is the only measured setting that falls below the 100 FPS threshold. The difference between Low and Ultra is 48 FPS, or 35%, which is consistent with the scaling pattern observed at 1440p.

The data reveals that the Medium preset provides the most complete dataset, with minimum and maximum FPS values recorded at every resolution. This suggests that the benchmark harness found this setting to be the most representative of typical gameplay conditions. The minimum FPS values at Medium settings are 285 FPS at 1080p, 190 FPS at 1440p, and 108 FPS at 4K, all of which are well above the thresholds for smooth gameplay.

The frame rate differences between settings are more pronounced at 1080p than at higher resolutions. This indicates that at 1080p, the CPU is the primary bottleneck, as the GPU has more headroom to render additional visual effects without impacting performance significantly. At 4K, the GPU becomes the limiting factor, and the differences between settings compress as the GPU works harder to render each frame.

Resolution Scaling

The data shows that frame rates scale predictably with resolution. From 1080p to 1440p, the average FPS drops by approximately 23-30% across all settings. For example, at High settings, the drop is from 296 FPS to 198 FPS, a reduction of 98 FPS or 33%. At Low settings, the drop is from 368 FPS to 246 FPS, a reduction of 122 FPS or 33%. This consistent scaling pattern indicates that the bottleneck shifts evenly as resolution increases.

From 1440p to 4K, the scaling becomes more aggressive. At High settings, the drop is from 198 FPS to 112 FPS, a reduction of 86 FPS or 43%. At Low settings, the drop is from 246 FPS to 139 FPS, a reduction of 107 FPS or 43%. This steeper decline suggests that the GPU is becoming the limiting factor at 4K, as the number of pixels increases by 2.25 times from 1440p to 4K.

The overall scaling from 1080p to 4K shows a significant performance reduction. At High settings, the drop is from 296 FPS to 112 FPS, a reduction of 184 FPS or 62%. At Low settings, the drop is from 368 FPS to 139 FPS, a reduction of 229 FPS or 62%. This consistent 62% reduction across settings indicates that the resolution scaling is uniform and that neither component is disproportionately bottlenecked at any resolution.

The data suggests that the CPU is the primary limiting factor at 1080p. The frame rates at 1080p are extremely high, exceeding 300 FPS on average for the Low and Medium presets. This indicates that the GPU has significant headroom at this resolution, and the CPU is likely the component preventing even higher frame rates. As resolution increases, the GPU becomes more utilized, and the frame rates drop accordingly.

At 4K, the GPU is clearly the limiting component. The Ultra preset at 4K averages 91 FPS, which is below the 100 FPS threshold that many users consider the minimum for smooth gameplay. The fact that the Low preset at 4K only achieves 139 FPS, compared to 368 FPS at 1080p, further confirms that the GPU is being pushed to its limits at this resolution.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on the Raptor Lake architecture. It has a base clock of 2.50 GHz and a boost clock of 4.60 GHz, with a 20 MB shared L3 cache and 1.25 MB L2 cache per core. The CPU's synthetic benchmarks show strong multi-threaded performance, with a Cinebench R23 multi-core score of 22,604 and a single-core score of 3,191. The PassMark multi-thread score is 25,032, and the single-thread score is 3,634.

In Roblox, the CPU's role is primarily to handle game logic, physics, and the rendering thread. The data shows that at 1080p, the CPU is the bottleneck, as evidenced by the high frame rates that exceed 300 FPS. The CPU's 10 cores and 16 threads provide ample headroom for Roblox's workload, which is typically not heavily multi-threaded. The CPU's performance in synthetic benchmarks, particularly the 3DMark 16-thread score of 7,314 and the 4-thread score of 3,459, indicates that it can handle both lightly and heavily threaded tasks effectively.

The CPU's clock speeds are more relevant than core count for Roblox. The boost clock of 4.60 GHz provides the single-threaded performance needed for high frame rates in a game that is largely limited by the main game thread. The single-core benchmarks, such as the Cinebench R15 single-core score of 321 and the Geekbench single-core score of 1,996, confirm that the CPU has strong single-threaded capabilities.

The CPU's cache configuration also plays a role in Roblox performance. The 20 MB shared L3 cache and 1.25 MB L2 cache per core help reduce memory latency, which is important for a game that frequently accesses game assets. The PassMark data compression score of 311,364 and random string sorting score of 32,076 indicate that the CPU handles data-intensive tasks well, which can benefit Roblox's asset loading and management.

The CPU's TDP of 65 watts is modest, and the fact that it uses the Intel Socket 1700 platform with DDR4 or DDR5 memory support means it can be paired with a variety of motherboards. The CPU's launch MSRP is $196, but the data shows that its performance in Roblox is not limited by its price point. The 77th percentile ranking versus all CPUs confirms that it is a capable processor for this game, even if it is not the absolute fastest option available.
