Roblox

Roblox is not a demanding title by modern standards, but the Intel Core Ultra X9 388H and NVIDIA GeForce RTX 4080 combination still delivers a wide spread of performance that scales predictably with resolution and settings. The data shows this combo ranks 945th out of 3010 tested combinations, placing it in the 69th percentile of all tested systems for this game. This is a strong result, though not a top-tier one, indicating that while the hardware is capable of very high frame rates, other combinations in the database achieve even higher scores in Roblox, likely due to the game's sensitivity to single-thread CPU performance.

The measured frame rates are consistently high across all tested configurations, with the lowest average being 114 FPS at 4K Ultra and the highest reaching 461 FPS at 1080p Low. The performance gap between the lowest and highest settings is significant, but even the most demanding preset at 4K remains comfortably above the 60 FPS threshold. The RTX 4080's 16 GB of VRAM and high bandwidth are more than sufficient for Roblox, which is not a VRAM-intensive title. The Ultra X9 388H's 16 cores and high boost clock provide ample processing power, though the game's engine appears to favor higher clock speeds over core counts, as evidenced by the relatively modest multi-core benchmark scores compared to its single-thread results.

GPU Role

The NVIDIA GeForce RTX 4080 is a high-end graphics card built on the Ada Lovelace architecture with a 5 nm process. It features 9728 shading units and 76 ray tracing cores, which are far more than Roblox requires, but the card's performance in this game is primarily dictated by its raw rasterization power. The GPU has a base clock of 2205 MHz and a boost clock of 2505 MHz, which are relatively high and contribute to the card's ability to push very high frame rates in a game like Roblox that does not rely heavily on complex shaders or effects.

The RTX 4080 comes with 16 GB of GDDR6X memory on a 256-bit bus, yielding a bandwidth of 716.8 GB/s. This memory configuration is excessive for Roblox, which typically uses only a fraction of a gigabyte of VRAM at any given resolution. The data confirms this, as the card maintains high average FPS even at 4K Ultra, with no indication that memory capacity or bandwidth is a bottleneck. The GPU's pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are also far beyond the needs of this game.

The GPU's performance in Roblox scales predictably with resolution. At 1920x1080, the average FPS ranges from 301 at Ultra to 461 at Low. At 2560x1440, the range is 201 to 308 FPS. At 3840x2160, the range drops to 114 to 174 FPS. This shows a clear reduction in performance as resolution increases, but even at the highest resolution and settings, the card maintains an average of 114 FPS, which is above the standard 60 FPS target. The RTX 4080's benchmark percentile of 86 vs all GPUs indicates it is a top-tier card, and its nearest rivals, such as the RTX 4080 SUPER and Radeon Pro W5700X, score within 1.1% of it, confirming that this GPU is at the upper echelon of performance.

CPU Role

The Intel Core Ultra X9 388H is a mobile processor with 16 cores and 16 threads, built on the Panther Lake architecture with a 3 nm process. It has a base clock of 2.10 GHz and a boost clock of 5.10 GHz, which is a wide turbo range. For Roblox, which is not heavily multithreaded, the CPU's high boost clock is more important than its core count. The single-core performance is strong, as evidenced by a Cinebench R23 single-core score of 2200.5 and a PassMark single-thread score of 4280.

The CPU's multi-core performance is also robust, with a Cinebench R23 multi-core score of 18911 and a Cinebench R20 multi-core score of 13101.
