Roblox

Roblox with the Intel Core i5-12400 and AMD Radeon RX 6700 XT delivers an exceptionally high-performance experience, with the data indicating that frame rates remain well above playable thresholds even at the most demanding settings. The combination of a modern 6-core processor and a high-end RDNA 2 graphics card results in a system that is heavily biased toward GPU limitation at higher resolutions, while showcasing the CPU's strength at 1080p. The measured FPS across all resolutions and settings paints a picture of a combo that is overqualified for this title, offering headroom that is rarely fully utilized.

Resolution Scaling

The performance drop from 1080p to 4K is significant, but the absolute numbers remain impressive. At 1080p with Low settings, the combo produces 370.3 FPS. Moving to 1440p at the same settings reduces this to 245 FPS, a 33.8% decrease. Scaling further to 4K at Low settings yields 139.2 FPS, which is 62.4% lower than the 1080p result. This pattern is consistent across all settings presets, confirming that the rendering load is scaling predictably with pixel count.

The data suggests a clear shift in the system's bottleneck as resolution increases. At 1920x1080, the frame rates are so high (241.8 FPS at Ultra, 294.7 FPS at High) that the Intel Core i5-12400 is likely reaching its performance ceiling. The gap between Low and Ultra settings at 1080p is 128.5 FPS, indicating that the GPU is not fully saturated and the CPU is dictating the maximum output. At 3840x2160, however, the gap between Low (139.2 FPS) and Ultra (92.6 FPS) narrows to 46.6 FPS, showing that the AMD Radeon RX 6700 XT is now the primary limiting factor, as the increased pixel workload consumes its available resources. The 4K Ultra result of 92.6 FPS is still highly playable, but the scaling behavior points to the GPU being the definitive constraint at this resolution.

How This Combo Ranks

In the database of tested combinations, this specific pairing ranks at position 1003 out of 1800 combos for Roblox. This places it in the 55.7th percentile of all tested systems, which is a solid mid-to-upper-tier ranking. While the raw frame rates are exceptionally high, the rank indicates that many other combinations, likely featuring even more powerful GPUs, achieve higher scores in this specific benchmark.

The ranking is contextualized by the individual component standings. The Intel Core i5-12400 has an average benchmark score of 19850, placing it in the 77th percentile of all CPUs. Its closest rival, the Intel Core i7-9700, scores 19831, a mere 0.1% difference, making them effectively equivalent in overall processing power. Similarly, the AMD Radeon RX 6700 XT sits in the 77th percentile of all GPUs with an average score of 33721. Its nearest rival, the AMD Radeon RX 6800, is just 0.7% faster, while the AMD Radeon HD 7950 is 1% slower. This data suggests that while both components are individually strong, the combo's overall rank is influenced by the game's specific demands and the performance of other pairings that may include higher-tier parts.

GPU Role

The AMD Radeon RX 6700 XT plays a decisive role in shaping the Roblox experience, particularly at higher resolutions. The GPU is based on the RDNA 2.0 architecture and features 12 GB of GDDR6 memory on a 192-bit bus, providing a memory bandwidth of 384.0 GB/s. This substantial memory allocation and bandwidth are more than sufficient for Roblox's typical asset sizes, ensuring that texture streaming and memory-intensive scenes do not cause hitches. The GPU's clock speeds are also a factor; with a base clock of 2321 MHz and a boost clock of 2581 MHz, it is built for high throughput.

The GPU's performance in synthetic benchmarks reinforces its capabilities. Its Passmark G3D score is 19786, and its performance in more modern APIs is strong, with a Geekbench Vulkan score of 108032 and a Geekbench OpenCL score of 100730. These scores indicate robust compute and rendering capabilities. The GPU's 2560 shading units and 40 ray accelerators provide the raw processing power needed to handle the game's visual effects. The data shows that at 4K Ultra, the GPU is the limiting factor, producing 92.6 FPS. This is still a smooth experience, but it is the lowest result in the measured set, confirming that the GPU's workload is the primary barrier to even higher frame rates at this resolution. The fact that it can maintain over 90 FPS at 4K Ultra underscores its strength, but the scaling data clearly identifies it as the performance ceiling for this pairing.
