Roblox

The Intel Core i5-13400F paired with the AMD Radeon RX 6800 XT ranks 648th out of 1800 tested combinations for Roblox. This places the combo in the 64th percentile of all tested systems, meaning it outperforms roughly two-thirds of the configurations in the database while remaining behind the top tier of hardware. The ranking reflects a strong mid-to-high tier pairing that is capable of delivering high frame rates across most settings, though it does not sit among the absolute fastest combinations for this sandbox title.

How This Combo Ranks

The combo's rank of 648 out of 1800 tested combos indicates a solid position in the overall distribution. The CPU itself holds an 82nd percentile ranking against all processors, while the GPU sits at an 87th percentile against all graphics cards. These individual percentiles suggest that both components are well above average, and their combined performance in Roblox is consistent with that expectation. The system is not a top performer, but it is clearly positioned in the upper half of the field, with a margin of about 64 percent of tested combos falling below it. This rank is meaningful because Roblox is a lightweight title by modern standards; even mid-range hardware can achieve high frame rates, and this pairing pushes well beyond that threshold.

GPU Role

The AMD Radeon RX 6800 XT brings 16 GB of GDDR6 memory on a 256-bit bus, delivering 512.0 GB/s of bandwidth. Its memory clock runs at 2000 MHz, which translates to 16 Gbps effective. The GPU's base clock is 1825 MHz, with a game clock of 2015 MHz and a boost clock of 2250 MHz. These specifications are substantial for a game like Roblox, which does not typically stress memory bandwidth or raw fill rates to the same degree as modern AAA titles. The GPU's 4608 shading units and 128 ROPs provide ample pixel throughput, with a pixel rate of 288.0 GPixel/s and a texture rate of 648.0 GTexel/s. In the context of Roblox, the GPU is rarely the primary bottleneck; the measured frame rates suggest that even at 4K Ultra, the card is not saturated. The GPU's benchmark scores reinforce this: a Passmark G3D score of 24980 and a 3DMark Steel Nomad DX12 score of 3689 place it near the NVIDIA GeForce RTX 4070 Ti SUPER, which trails by 2.6 percent in average benchmark score. The RX 6800 XT's average benchmark score of 49982 puts it 0.5 percent ahead of the Intel Arc A550M and 1.9 percent ahead of the NVIDIA CMP 50HX, indicating a competitive mid-range-to-high-end position.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor from the Raptor Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. It features 20 MB of shared L3 cache and supports dual-channel DDR4 or DDR5 memory. In Roblox, the CPU's role is more pronounced than in many GPU-bound titles, because the game's physics and scripting can create single-threaded bottlenecks. The CPU's single-thread performance is strong, as indicated by a Passmark single-thread score of 3634 and a Geekbench single-core score of 2301. Multi-threaded performance is also robust, with a Cinebench R23 multi-core score of 21279 and a Passmark multithread score of 25032. The CPU's average benchmark score of 25236 is 0.1 percent ahead of the Intel Core i7-13620H and 0.5 percent behind the AMD Ryzen 5 5600X3D. This places the i5-13400F in a tight cluster of similar-performing processors, meaning that in Roblox, the CPU's headroom is sufficient to keep frame rates high without being the limiting factor at most settings.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce an average of 464.9 FPS, which drops to 423.4 FPS on Medium and 372.5 FPS on High. Ultra settings reduce the average to 301.6 FPS. The gap between Low and Ultra is 163.3 FPS, indicating that the GPU is scaling with graphical load, but even the lowest figure remains far above the refresh rate of standard monitors. Moving to 2560x1440, the averages are 308.9 FPS on Low, 282.7 FPS on Medium, 252.2 FPS on High, and 204 FPS on Ultra. The drop from 1080p to 1440p is consistent, with a roughly 34 percent reduction from Low to Low, but the system still maintains over 200 FPS at the highest settings. At 3840x2160, the performance falls further: Low averages 176 FPS, Medium averages 158.6 FPS, High averages 143.6 FPS, and Ultra averages 113.1 FPS. Even at 4K Ultra, the frame rate remains above 100 FPS, which is a strong result for a game that is not typically considered demanding. The data shows a clear, monotonic decrease in frame rates as resolution and settings increase, with no anomalies or unexpected dips.

Resolution Scaling

The scaling from 1080p to 4K reveals a shift in the limiting component. At 1080p Low, the system achieves 464.9 FPS, which is likely close to the CPU's practical limit for Roblox's game logic. Moving to 1440p Low drops this to 308.9 FPS, a 33.5 percent reduction, and at 4K Low it falls to 176 FPS, a 62.1 percent reduction from the 1080p baseline. This pattern suggests that at lower settings, the GPU becomes more involved as resolution increases, but the CPU still has headroom. At Ultra settings, the frame rate drops from 301.6 FPS at 1080p to 204 FPS at 1440p (32.4 percent reduction) and then to 113.1 FPS at 4K (62.5 percent reduction from 1080p). The consistent percentage drops across settings indicate that the GPU is the primary scaling factor when moving to higher resolutions, while the CPU maintains a stable floor. The fact that 4K Ultra still exceeds 100 FPS implies that the GPU is not fully saturated, and the CPU is keeping up with the frame delivery. This is a well-balanced pairing for Roblox, where neither component is severely bottlenecked at any tested resolution.

Settings Recommendations

The measured rows suggest that Ultra settings at 1080p and 1440p are the best choices for most users, as they deliver 301.6 FPS and 204 FPS respectively, both well above the 144 Hz refresh rate common in gaming monitors. At 4K, Ultra drops to 113.1 FPS, which is still playable on high-refresh displays but may not fully utilize a 144 Hz panel. For users prioritizing maximum frame rates, Low settings at 1080p offer 464.9 FPS, but this comes with reduced visual fidelity. Medium settings at 1440p provide a balanced 282.7 FPS, which is a strong middle ground for those with 1440p monitors. At 4K, High settings at 143.6 FPS offer a better experience than Ultra's 113.1 FPS, with a modest visual difference that may not justify the 30.5 FPS loss. The optimal recommendation based on the data is to use Ultra at 1080p or 1440p for the best combination of visual quality and high frame rates, while at 4K, High settings are the most sensible choice to maintain a smoother experience. The system is capable of exceeding 100 FPS at every setting and resolution tested, so users can prioritize visual quality without sacrificing playability.
