Settings Recommendations

The measured frame rates for this combination in Roblox reveal a system with substantial headroom. At 1920x1080, the Ultra preset delivers an average of 367.3 FPS, while the High preset reaches 449.8 FPS, and the Medium preset hits 507.1 FPS. The Low preset at this resolution produces 560.5 FPS, which represents the absolute ceiling of the measured data.

For 2560x1440, the pattern remains consistent. Ultra produces 240.4 FPS, High delivers 302.5 FPS, Medium reaches 339.9 FPS, and Low tops out at 373.8 FPS. The gap between settings narrows as resolution increases, with the difference between Low and Ultra shrinking from 193.2 FPS at 1080p to 133.4 FPS at 1440p.

At 3840x2160, the Ultra preset still manages 138.8 FPS, while High achieves 169.7 FPS, Medium delivers 192.1 FPS, and Low reaches 213.3 FPS. Even at 4K, every measured preset remains comfortably above common display refresh rate thresholds.

The data suggests that the High preset offers the optimal balance between visual fidelity and performance. At 1080p, High is 82.5 FPS behind Medium but 82.5 FPS ahead of Ultra, putting it in a sensible middle ground. At 1440p, High sits 37.4 FPS behind Medium and 62.1 FPS ahead of Ultra. At 4K, High trails Medium by 22.4 FPS but leads Ultra by 30.9 FPS.

Players targeting very high refresh rate displays should consider Medium, which exceeds 500 FPS at 1080p and clears 330 FPS at 1440p. Those prioritizing visual quality over raw speed can still use Ultra, given that even the heaviest preset stays above 138 FPS at 4K. The measured data indicates no preset in this lineup produces a poor experience; the choice depends entirely on display capabilities and visual preferences.

GPU Role

The NVIDIA GeForce RTX 4070 SUPER serves as the primary driver of Roblox's performance in this configuration. Its 12 GB of GDDR6X memory on a 192-bit bus provides 504.2 GB/s of bandwidth, which proves ample for a sandbox title that rarely stresses memory capacity. The GPU operates with a base clock of 1980 MHz and a boost clock of 2475 MHz, with memory clocked at 1313 MHz (21 Gbps effective).

The Ada Lovelace architecture, built on TSMC's 5 nm process, packs 35,800 million transistors into a 294 mm² die. The GPU contains 7168 shading units, 224 texture mapping units, and 80 raster output pipelines. Its 56 ray tracing cores and 224 tensor cores enable 35.48 TFLOPS of FP32 performance and matching FP16 throughput.

Benchmark data places this GPU in the 84th percentile among all GPUs tested, with an average benchmark score of 42576. Its nearest rivals include the NVIDIA RTX A6000 with a score of 42653 (0.2% higher), the AMD Radeon RX 7650 GRE at 42723 (0.3% higher), and the AMD Radeon Pro 580X at 41991 (1.4% lower). The NVIDIA Tesla M40 trails at 41897, a 1.6% deficit.

The frame rate scaling across settings reflects the GPU's capability. At 1080p, the jump from Low to Ultra costs 193.2 FPS, demonstrating that even the highest preset leaves the GPU with significant headroom. At 4K, the same preset transition costs 74.5 FPS, showing that resolution scaling moderates the performance delta. The GPU's 84th percentile standing suggests it is well above average for gaming workloads, and Roblox's measured results confirm this — the RTX 4070 SUPER never dips below 138 FPS even under the heaviest tested load.

CPU Role

The AMD Ryzen 5 8400F contributes the computational foundation for this Roblox configuration. This 6-core, 12-thread processor from the 8000 series uses the Zen 4 architecture on the Phoenix codename, fabricated on TSMC's 4 nm process. It houses 25,000 million transistors on a 178 mm² die, with a base clock of 4.20 GHz and a boost clock of 4.70 GHz.

The cache hierarchy consists of 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Memory support covers DDR5 with dual-channel operation, providing 83.2 GB/s of bandwidth. The CPU connects via PCIe Gen 4 with 20 lanes from the CPU alone.

Synthetic benchmarks show a balanced profile. The 3DMark suite records 951 for single-thread, 1874 for 2-thread, 3563 for 4-thread, 5275 for 8-thread, and 6165 for max-thread tests. Cinebench results include 296 for R15 single-core and 2101 for multi-core, 1236 for R20 single-core and 8757 for multi-core, and 2943 for R23 single-core with 20851 for multi-core. PassMark tests show 3684 for single-thread, 24530 for multithread, 74304 for integer math, 46096 for floating point math, and 288994 for data compression.

The processor sits in the 82nd percentile among all CPUs, with an average benchmark score of 25064. Its nearest rivals include the AMD Ryzen 7 2700X at 25057 (0% difference), the AMD Ryzen AI 5 PRO 340 at 25099 (0.1% lower), and the AMD EPYC 9474F at 25103 (0.2% lower). The AMD Ryzen 5 7500F scores 24993, a 0.3% deficit.

In Roblox's measured results, the CPU's impact becomes visible at lower resolutions where frame rates exceed 500 FPS. At 1080p Low, the 560.5 FPS result likely approaches the CPU's instruction throughput ceiling. The 4.70 GHz boost clock and strong single-thread performance — evidenced by the 2943 Cinebench R23 single-core score — support the high frame rates Roblox demands from a single primary game thread.

How This Combo Ranks

This specific combination of AMD Ryzen 5 8400F and NVIDIA GeForce RTX 4070 SUPER ranks 325th out of 1800 tested combos in Roblox. This places the configuration in the top 18.1% of all measured pairings, indicating a strong overall result for this sandbox title.

The ranking reflects the combined capabilities of both components. The GPU's 84th percentile standing and the CPU's 82nd percentile standing suggest a well-matched pairing where neither component dramatically bottlenecks the other. The measured frame rates across all resolutions and settings support this interpretation — the system delivers high performance consistently.

The 325th rank out of 1800 combos means the majority of tested systems fall behind this configuration. Given that the GPU and CPU each rank near the 82-84th percentile individually, a combined rank in the top 18% aligns with expectations for two above-average components working together. The modest gap between individual component percentiles and the combined rank likely stems from the game's specific engine characteristics, which may favor certain hardware configurations over others.
