Roblox

The Intel Core i5-12400F and NVIDIA GeForce RTX 3070 combination delivers exceptionally high frame rates in Roblox, a Sandbox title released on 2006-08-31. The measured data shows this pairing ranks 842nd out of 1800 tested combos in this game, placing it in the upper half of the database. Across all tested resolutions and settings, the average frame rates never drop below 103.5 FPS, which indicates a highly fluid experience even under the most demanding conditions tested. The benchmark results paint a clear picture of a system that is heavily overqualified for the graphical demands of this title, with performance scaling that reveals distinct roles for the CPU and GPU.

CPU Role

The Intel Core i5-12400F is a 6-core, 12-thread processor from the Core 12th Gen series, built on the Alder Lake architecture using a 10 nm process. It operates with a base clock of 2.50 GHz and a boost clock of 4.40 GHz, which is critical for Roblox’s single-threaded tendencies. The CPU’s 3dmark single-thread score of 909 and Cinebench R23 single-core score of 2332 indicate strong per-core performance, which directly translates to the high frame rates seen at 1080p where the CPU is more likely to be the limiting factor. In contrast, its multi-threaded capabilities are solid for a desktop part, with a Cinebench R23 multicore score of 16518 and a Passmark multithread score of 19433, but Roblox’s engine does not heavily leverage these extra threads.

The processor’s average benchmark score of 19221 places it in the 77th percentile of all CPUs, and its nearest rivals show a tight cluster of competition. It is essentially tied with the Intel Core i7-8700K, which scores 19210, showing a negligible 0.1% delta, and the Intel Core i5-1335U, which scores 19167, a 0.3% delta. The data shows it is slightly ahead of the AMD Ryzen 5 7533HS, which scores 19364, with the i5-12400F being 0.7% slower, and it holds a 1.3% advantage over the AMD EPYC 7773X, which scores 18979. This positioning suggests that the CPU is a balanced performer, but for Roblox specifically, the 2.50 GHz base clock and 4.40 GHz boost clock are the primary drivers of the 413.2 FPS average seen at 1080p Low settings, where the CPU is not bottlenecked by the GPU.

The 18 MB of shared L3 cache and 1.25 MB L2 cache per core help maintain responsive frame pacing. In the measured results, the CPU’s influence is most apparent at 1080p, where the frame rates vary significantly between settings, from 269.4 FPS at Ultra to 413.2 FPS at Low, showing that the CPU can push more frames when the GPU has less work to do. The 3dmark 16-thread score of 5895 and 2-thread score of 1699 highlight that while the chip has multi-core headroom, its dual-thread performance is what matters most for this game’s physics and scripting logic.

GPU Role

The NVIDIA GeForce RTX 3070 is an Ampere-architecture GPU built on Samsung’s 8 nm process, featuring 5888 shading units and 96 ROPs. It comes with 8 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 448.0 GB/s, which is more than sufficient for Roblox’s stylized textures and simple geometry. The GPU’s base clock is 1500 MHz with a boost clock of 1725 MHz, and its FP32 performance is rated at 20.31 TFLOPS. This raw compute power translates into a Passmark G3D score of 22214 and a 3dmark Steel Nomad DX12 score of 3162, positioning the card in the 72nd percentile of all GPUs.

The RTX 3070’s nearest rivals in the database include the AMD FirePro S7150, which scores 28409, a 0.6% performance delta against the RTX 3070’s average benchmark score of 28238. It is also compared to the AMD Radeon RX 6600 XT, which scores 27985, showing the RTX 3070 is 0.9% faster, and the NVIDIA GeForce GTX 980 Ti, which scores 27956, a 1% lead. The data shows the RTX 3070 is 1.1% slower than the AMD Radeon R9 M295X, which scores 28541. These deltas are all within a narrow band, but for Roblox, the GPU’s role becomes more pronounced as resolution increases.

At 4K (3840x2160), the GPU’s memory bandwidth and shading power are tested more heavily. The average FPS at 4K High is 127.3, which drops to 103.5 FPS at 4K Ultra, indicating that the GPU is becoming the limiting component at this resolution. The 8 GB VRAM is ample for Roblox’s asset sizes, and the 448.0 GB/s bandwidth ensures no memory bottlenecks at the tested settings. The GPU’s 165.6 GPixel/s pixel rate and 317.4 GTexel/s texture rate are more than capable of handling the rendering load, but the frame rate drop from 1080p to 4K shows that the RTX 3070 is doing the heavy lifting in the higher resolution scenarios.

Resolution Scaling

The measured FPS data reveals a clear scaling pattern from 1080p to 4K, demonstrating how the workload shifts between the CPU and GPU. At 1080p with High settings, the system achieves 331.4 FPS, but this drops to 221.1 FPS at 1440p and further to 127.3 FPS at 4K. This represents a 61.6% reduction in frame rate from 1080p to 4K, which is a significant drop that indicates the GPU is becoming the primary bottleneck at higher resolutions.

Looking at the Low settings, the progression is even more telling. At 1080p Low, the system hits 413.2 FPS, which is the highest measured frame rate in the dataset. At 1440p Low, this drops to 277.3 FPS, and at 4K Low, it falls to 156.1 FPS. The fact that the 1080p Low result is so much higher than the 1440p High result (413.2 vs 221.1) suggests that at 1080p, the CPU is able to feed the GPU enough frames to reach the upper limit of its rendering capacity, while at 4K, the GPU’s pixel throughput becomes the limiting factor.

The data shows that the scaling from 1440p to 4K is steeper than from 1080p to 1440p. For example, at Ultra settings, the system goes from 269.4 FPS at 1080p to 181.5 FPS at 1440p, a 32.6% drop, but then from 181.5 FPS at 1440p to 103.5 FPS at 4K, a 43.0% drop. This pattern confirms that the RTX 3070 is the limiting component at 4K, while the i5-12400F’s strong single-thread performance keeps frame rates high at lower resolutions. The benchmark results indicate that the system is CPU-bound at 1080p and GPU-bound at 4K, with the crossover point occurring somewhere between 1440p and 4K depending on the settings preset.

Settings Recommendations

The measured rows provide clear guidance on which settings preset offers the best experience. At 1080p, all presets deliver over 269 FPS, which exceeds the refresh rate of most high-end monitors. The High preset at 331.4 FPS is a strong choice, as it provides a large improvement in visual fidelity over Low (413.2 FPS) while still maintaining a frame rate that is well above any display’s capabilities. The Medium preset at 376.1 FPS offers a middle ground, but the jump to High is marginal in terms of FPS cost.

For 1440p, the High preset at 221.1 FPS is the recommended configuration. It offers a substantial visual upgrade over Medium (249.8 FPS) while keeping the frame rate well above the 144 Hz threshold. The Ultra preset at 181.5 FPS is also viable, but the 17.9% drop from High to Ultra may not justify the visual gains in a stylized game like Roblox. At 4K, the situation changes. The High preset at 127.3 FPS is the best balance, as it provides a smooth experience on 120 Hz displays. The Medium preset at 141.1 FPS is also acceptable, but the Low preset at 156.1 FPS sacrifices too much visual quality for a relatively small FPS gain. The Ultra preset at 103.5 FPS is playable but approaches the lower bound of what is considered smooth for fast-paced gameplay.
