CPU and GPU Roles

The data from Inside clearly shows that the NVIDIA GeForce RTX 5090 is the primary driver of frame rate performance. At 4K, the difference between the Low and Ultra presets is substantial: 241.9 FPS versus 146 FPS, a gap of 95.9 FPS. This scaling indicates that the GPU is handling the bulk of the rendering workload, and its capacity is the limiting factor when pushing higher quality settings. The RTX 5090's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth provide more than enough resources for this 2016 title, which was released before these specifications were even conceivable.

At lower resolutions, the CPU's role becomes more apparent, though it never becomes a constraint. At 1080p, the gap between Ultra and Low narrows to 75.6 FPS (241.7 vs 317.3), suggesting that the CPU is starting to provide more of the frame time. The i5-12400, with its 6 cores and 12 threads, delivers a single-thread benchmark score of 910 in 3DMark and a Passmark single-thread score of 3,456, which is more than adequate for a puzzle platformer. The CPU's average benchmark score of 18,683 places it in the 72nd percentile, and its nearest rivals show it is performing within 0.9% of similarly priced alternatives, meaning it is well-matched to avoid bottlenecking the GPU.

The scaling between resolutions further confirms this split. Moving from 1080p to 1440p at Ultra settings reduces the average frame rate from 241.7 FPS to 217.4 FPS, a modest 10.0% decrease. Moving from 1440p to 4K at Ultra reduces the average from 217.4 FPS to 146 FPS, a 32.8% decrease. The larger drop at higher resolutions is characteristic of GPU-bound scenarios, where the pixel throughput demands more from the graphics card. The RTX 5090's pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s are the specifications that enable these high figures, even at 4K.

How This Combo Ranks
