This combo ranks in the 68th percentile of all tested combinations, placing it in the upper tier of systems capable of running this sandbox title.

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, built on a 10 nm process. It operates with a base clock of 2.50 GHz and a boost clock of 4.60 GHz, features 20 MB of shared L3 cache, and supports both DDR4 and DDR5 memory. Its benchmark scores reveal a processor with balanced single-threaded and multi-threaded capabilities: it achieves a 3DMark single-thread score of 960 and a multi-thread score of 7307, while Cinebench R23 results show 3004 points single-core and 21279 points multi-core. The processor's average benchmark score of 25236 places it in the 82nd percentile of all CPUs, indicating strong overall performance.

In the context of Roblox, the CPU's role is primarily to feed the GPU with draw calls and physics calculations. The 13400F's single-thread performance is particularly relevant, as Roblox's engine tends to be sensitive to per-core performance rather than raw core counts. The data shows that at 1080p Low settings, the system achieves 473.6 FPS, which is a 23.9% increase over the 4K Low result of 181.4 FPS. This scaling pattern suggests that even at the lowest settings, the GPU is the limiting factor, as the CPU has sufficient headroom to push far beyond the observed frame rates. The processor's 3DMark 2-thread score of 1880 and 4-thread score of 3459 indicate that it can handle lightly-threaded workloads efficiently, which aligns with Roblox's moderate CPU demands.

Compared to its nearest rivals, the 13400F is essentially tied with the Intel Core i7-13620H (deltaPct 0.1) and slightly behind the AMD Ryzen 5 5600X3D (deltaPct -0.5). It also edges out the AMD EPYC 9474F and AMD Ryzen AI 5 PRO 340, both with a deltaPct of 0.5. This indicates that the 13400F's compute capabilities are well within the range needed for Roblox, and the actual frame rate ceiling is determined by the GPU rather than the CPU.

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

The AMD Radeon RX 9070 is a high-end graphics card based on the RDNA 4.0 architecture, utilizing the Navi 48 chip on a 4 nm process from TSMC. It features 16 GB of GDDR6 memory on a 256-bit bus, delivering 644.6 GB/s of bandwidth. The GPU operates at a base clock of 1330 MHz, a game clock of 2070 MHz, and a boost clock of 2520 MHz, with memory running at 2518 MHz (20.1 Gbps effective). The card has 3584 shading units, 224 texture mapping units, and 128 raster operation units, with a peak FP32 performance of 36.13 TFLOPS.

For Roblox, the RX 9070's 16 GB VRAM is more than sufficient, as the game's texture and geometry demands are modest compared to modern AAA titles. The GPU's raw throughput is what drives the high frame rates observed in the data. At 4K Ultra settings, the system still manages 118.3 FPS, which demonstrates the card's ability to handle the game's maximum visual fidelity without significant frame rate drops. The GPU's average benchmark score of 34780 places it in the 79th percentile of all GPUs, and its nearest rivals include the NVIDIA A2 (deltaPct -0.2) and NVIDIA Quadro GV100 (deltaPct 0.3), showing that the RX 9070 sits in a competitive performance bracket.

The GPU's performance scaling across settings is consistent with its specifications. At 4K, moving from Low to Ultra reduces frame rates by 34.8% (from 181.4 to 118.3 FPS), which is a moderate penalty given the visual improvements. The 16 GB VRAM ensures that there is no memory capacity bottleneck at any resolution, allowing the GPU to focus entirely on rendering performance. The RX 9070's 128 ROPs and 564.5 GTexel/s texture rate are well-suited for Roblox's blocky-but-textured environments, and the card's DirectX 12 Ultimate support (12_2) ensures compatibility with the game's rendering pipeline.

The combination of the Intel Core i5-13400F and AMD Radeon RX 9070 ranks 585th out of 1800 tested combos, placing it in the 68th percentile of all systems benchmarked for Roblox. This is a strong showing, as it means this configuration outperforms roughly two-thirds of all tested combinations while still leaving room for higher-end setups to achieve even greater frame rates. The rank reflects the balanced nature of this pairing: the CPU's 82nd percentile standing and the GPU's 79th percentile standing combine to produce a system that is well-matched for Roblox's workload.

The data suggests that the GPU is the primary driver of this rank, as the RX 9070's robust specifications — 36.13 TFLOPS FP32 and 128 ROPs — are more than adequate for the game's rendering demands. The CPU's performance is sufficient to avoid becoming a bottleneck, as evidenced by the smooth scaling of frame rates across resolutions. At 1080p Low, the combo achieves 473.6 FPS, which is close to the practical limits of most displays, and even at 4K Ultra, it maintains 118.3 FPS, which is above the 60 FPS threshold for smooth gameplay. The rank of 585 indicates that while there are more powerful combos available, this system delivers a high-quality Roblox experience that will satisfy most users without requiring extreme hardware investments.

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

At 1920x1080, the system delivers its highest frame rates. Low settings produce an average of 473.6 FPS, which drops to 429.2 FPS at Medium and 382 FPS at High. Ultra settings reduce the average to 311 FPS, which is still exceptionally high and represents a 34.3% decrease from Low to Ultra. This resolution is clearly GPU-bound, as even the most demanding settings fail to push the frame rate below 300 FPS.

Moving to 2560x1440, the frame rates remain very high but show a noticeable reduction from 1080p. Low settings average 319.9 FPS, Medium settings 290.8 FPS, High settings 251.4 FPS, and Ultra settings 205.7 FPS. The scaling from Low to Ultra at 1440p is a 35.7% drop, which is consistent with the pattern seen at 1080p. The 1440p results indicate that the GPU has sufficient headroom to maintain high refresh rates, though the frame rate ceiling is clearly lower than at 1080p.

At 3840x2160, the system still delivers playable and often high frame rates. Low settings average 181.4 FPS, Medium settings 163.1 FPS, High settings 144 FPS, and Ultra settings 118.3 FPS. The drop from Low to Ultra at 4K is 34.8%, which is remarkably consistent with the percentage drops at other resolutions. This suggests that the performance scaling is primarily driven by the GPU's rendering load rather than any CPU limitation. The 4K Ultra result of 118.3 FPS is notable because it demonstrates that this combo can handle Roblox's maximum settings at 4K while staying well above the 60 FPS threshold.

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

Based on the measured frame rates, the High settings preset at 2560x1440 offers the best overall experience for most users. At 251.4 FPS, it provides a 64.3% improvement over 4K High (144 FPS) while still delivering visually rich graphics. The 1440p High setting strikes an excellent balance between visual fidelity and frame rate, as it sits comfortably above the 240 Hz refresh rate that many high-end monitors support. For users with 4K displays, the High preset at 3840x2160 (144 FPS) is the recommended choice, as it provides a smooth experience that exceeds the 120 Hz threshold while maintaining good visual quality.

For users prioritizing maximum frame rates, the Low preset at 1920x1080 (473.6 FPS) is the clear winner, though this comes at the cost of visual quality. The Medium preset at 1440p (290.8 FPS) is a strong middle ground for those who want high frame rates without sacrificing too much visual detail. The Ultra preset, while visually the most impressive, shows the most significant performance penalties — at 4K Ultra (118.3 FPS), the frame rate drops below the 120 Hz mark, and at 1080p Ultra (311 FPS), it still delivers excellent performance but with diminishing returns over High (382 FPS). Given that the percentage difference between High and Ultra is relatively small (around 18-19% at each resolution), the High preset offers the best value in terms of visual quality per frame rate.

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 clear GPU-bound scenario. At Low settings, the average FPS drops from 473.6 at 1920x1080 to 181.4 at 3840x2160, representing a 61.7% reduction. This percentage drop closely matches the theoretical increase in pixel count — 4K has 4 times the pixels of 1080p, and the observed reduction is consistent with a system that is fully GPU-limited. The Medium settings show a similar trend, with a 62.0% drop from 429.2 to 163.1 FPS, while High settings drop by 62.3% (382 to 144 FPS) and Ultra settings drop by 61.9% (311 to 118.3 FPS).

The consistency of these percentage drops across all settings is the key indicator that the GPU is the limiting component. If the CPU were the bottleneck, we would expect to see a smaller percentage drop at lower resolutions, where the CPU's frame rate ceiling would cap performance. Instead, the frame rates scale almost perfectly with pixel count, demonstrating that the RX 9070 is the primary constraint. The CPU's headroom is further confirmed by the fact that at 1080p Low, the system achieves 473.6 FPS, which is far above what most displays can even show, indicating that the 13400F is not preventing the GPU from reaching its full potential.

The scaling also shows that the GPU's performance is remarkably consistent across settings. The difference between Low and Ultra at each resolution is approximately 34-36%, which indicates that the game's visual settings have a moderate impact on GPU load. This suggests that even at Ultra settings, the RX 9070 is not being pushed to its absolute limit, as the frame rates remain high enough to leave performance headroom for more demanding scenes or future updates to the game.
