Roblox

The Intel Core i5-13400F paired with the NVIDIA GeForce RTX 4070 Ti SUPER delivers an extraordinary performance envelope in Roblox, a sandbox title that scales dramatically across resolutions. The measured data shows this combination is not merely playable but overwhelmingly fast, with frame rates that remain well above refresh-rate thresholds even at 4K. This analysis breaks down the scaling behavior, the combo’s standing among tested configurations, and the specific role each component plays.

Resolution Scaling

The frame rate drop from 1080p to 4K reveals a system that is severely CPU-limited at lower resolutions, with the GPU only beginning to assert its influence at higher pixel counts. At 1920x1080 with High settings, the combo produces 477.9 FPS. Moving to 2560x1440 drops that to 318.6 FPS, a 33% reduction. At 3840x2160, the average falls further to 177.6 FPS, which is a 63% decrease from the 1080p figure. This pattern—where each resolution step costs roughly a third of the remaining performance—indicates that the CPU’s single-thread throughput is the primary constraint at 1080p, while the GPU’s shading capacity becomes more relevant as pixel count grows.

The scaling across settings reinforces this interpretation. At 1080p Low, the combo hits 595.5 FPS, while at 4K Low it still manages 225 FPS. The delta between these extremes is 370.5 FPS. Contrast that with the Ultra preset, where 1080p yields 387.2 FPS and 4K drops to 147.1 FPS—a smaller absolute gap of 240.1 FPS. The Low preset’s larger absolute drop suggests that reducing graphical load removes GPU bottlenecks, exposing the CPU’s ceiling even at 4K. Conversely, the Ultra preset’s smaller absolute decline indicates that the GPU is doing more work, which compresses the frame rate range.

The most telling metric is the 4K to 1080p ratio. At High settings, the 4K result is 37% of the 1080p result. At Ultra, that ratio is 38%. At Low, it is 38%. The consistency of these ratios—hovering near 38% regardless of settings—implies a balanced scaling curve where neither component completely dominates. The i5-13400F, with its 10 cores and 16 threads, provides enough headroom that even at 4K Ultra the system never falls below 147.1 FPS, which remains a highly playable figure. The data suggests that for competitive play at high refresh rates, 1080p is the sweet spot, while 4K is reserved for visual fidelity with still-excellent frame rates.

How This Combo Ranks

In the database of tested CPU-GPU combinations for Roblox, this pairing holds the 222nd position out of 1,800 total combos. That places it in the top 12.3% of all tested configurations, a strong result for a mid-range CPU paired with a high-end GPU. The rank reflects the combination’s ability to sustain high frame rates across all resolutions, but it also shows that there is meaningful headroom above it—suggesting that other combinations, likely with faster single-threaded CPUs, achieve even higher peaks.

The CPU’s own percentile ranking illuminates this position. The i5-13400F sits at the 82nd percentile among all CPUs in aggregate benchmark scores, with an average score of 25,236. Its nearest rivals in the CPU benchmark hierarchy include the Intel Core i7-13620H, which scores 25,201 (a 0.1% delta), and the AMD Ryzen 5 5600X3D at 25,365 (a -0.5% delta). These sub-1% differences indicate that the i5-13400F is in a tightly contested performance tier, where the choice between these CPUs would have negligible impact on Roblox frame rates. The AMD EPYC 9474F and AMD Ryzen AI 5 PRO 340 also sit within 0.5% of the i5, further solidifying this cluster.

The GPU’s standing is similarly competitive. The RTX 4070 Ti SUPER ranks at the 86th percentile among all GPUs, with an average benchmark score of 48,704. Its nearest rivals include the NVIDIA CMP 50HX (49,071, a -0.7% delta) and the Intel Arc A550M (49,737, a -2.1% delta). The GPU’s percentile is slightly higher than the CPU’s, suggesting that the graphics card is the stronger component in this pairing. However, the combo’s rank in Roblox specifically—222 out of 1,800—indicates that the game’s engine is more sensitive to CPU performance than GPU raw power, given that the CPU sits at the 82nd percentile while the combo lands in the 88th percentile of tested combos.

Measured FPS Breakdown

The measured frame rates reveal a consistent hierarchy across all three resolutions. At 1920x1080, the Low preset produces 595.5 FPS, Medium produces 537.6 FPS, High produces 477.9 FPS, and Ultra produces 387.2 FPS. The step-down from Low to Medium is 57.9 FPS, from Medium to High is 59.7 FPS, and from High to Ultra is 90.7 FPS. The larger drop from High to Ultra suggests that the Ultra preset introduces effects that disproportionately tax the GPU, even at this resolution.

At 2560x1440, the same pattern holds but with narrower gaps. Low produces 395.7 FPS, Medium produces 358.7 FPS (a 37 FPS drop), High produces 318.6 FPS (a 40.1 FPS drop), and Ultra produces 258.3 FPS (a 60.3 FPS drop). The relative reduction from Low to Ultra is 34.7%, compared to 35% at 1080p, indicating that the scaling penalty is nearly identical across these two resolutions.

At 3840x2160, the frame rates compress further. Low produces 225 FPS, Medium produces 201.5 FPS (a 23.5 FPS drop), High produces 177.6 FPS (a 23.9 FPS drop), and Ultra produces 147.1 FPS (a 30.5 FPS drop). The total reduction from Low to Ultra is 77.9 FPS, or 34.6%. This consistency across resolutions—all showing roughly a 35% penalty from Low to Ultra—indicates that the settings presets scale uniformly, with no single preset introducing an anomalous bottleneck.

The 4K results are particularly notable for their absolute values. Even at Ultra, the combo maintains 147.1 FPS, which is above the refresh rate of most standard 4K monitors. The Low preset at 4K delivers 225 FPS, which is more than sufficient for high-refresh-rate 4K panels. The data shows that this combo never dips below 147 FPS in any measured configuration, making it an exceptionally capable Roblox machine at any resolution.

GPU Role

The RTX 4070 Ti SUPER plays a critical but secondary role in this pairing, given Roblox’s CPU-bound nature. The GPU’s specifications are substantial: 16 GB of GDDR6X memory on a 256-bit bus, providing 672.3 GB/s of bandwidth. This memory configuration is far beyond what Roblox requires, but it ensures that the GPU never becomes a memory-bandwidth bottleneck, even at 4K with high-resolution textures.

The GPU’s clock behavior is straightforward. The base clock is 2340 MHz, with a boost clock of 2610 MHz. The memory runs at 1313 MHz, which translates to 21 Gbps effective. These clocks, combined with the 8448 shading units and 264 texture mapping units, yield a pixel rate of 250.6 GPixel/s and a texture rate of 689.0 GTexel/s. The FP32 performance of 44.10 TFLOPS is more than adequate for a title like Roblox, which relies on simple geometry and lighting rather than heavy compute or ray tracing.

The GPU’s average benchmark score of 48,704 places it at the 86th percentile, which is higher than the CPU’s 82nd percentile. This suggests that the GPU has more headroom than the CPU in this pairing, meaning that if the CPU were upgraded, the GPU could likely push frame rates even higher. The nearest GPU rivals—the CMP 50HX at 49,071 and the RTX A2000 at 47,915—are within 2% of the 4070 Ti SUPER’s score, showing that this GPU is in a tightly competitive tier.

In Roblox specifically, the GPU’s role becomes more pronounced at higher settings and resolutions. The measured FPS drops from 595.5 at 1080p Low to 225 at 4K Low, a 62% reduction that is primarily driven by the GPU’s rendering load. At Ultra, the drop from 387.2 to 147.1 represents a 62% reduction as well, confirming that the GPU’s scaling penalty is consistent regardless of preset. The 16 GB VRAM is never a limiting factor in this game, and the 285 W TDP suggests the card has thermal headroom for sustained high-frequency operation, though the data does not include temperature or power measurements. The GPU’s Ada Lovelace architecture, built on a 5 nm process at TSMC, provides the efficiency to maintain these high frame rates without excessive power draw, though specific wattage figures are not part of the measured data.
