Graphics
The machine has the Intel Arc 140T, the iGPU used in the Intel Arrow Lake H/HX processor series. It’s quite a powerful integrated graphics setup. It shares the system DDR5 memory, it has 1024 cores, 64 TMUs, and 32 ROPs. It has 128 tensor cores and 8 ray tracing cores. And 74 GPU Peak TOPS (Int8). For an iGPU it’s a good specification.

As the chart shows, the AS Rock’s NUC scores an accomplished 139 FPS.
The machine with the i5-12400F hosts a dedicated graphics card (NVIDIA GeForce RTX 3060 Ti). It’s therefore no surprise it romps home in the test. I couldn’t remove the graphics card for the benchmark as the i5-12400F lacks integrated graphics.
800×600 is a very low resolution to play games. Let’s re-run the benchmark but at a higher resolution.

I generally consider 30 FPS is the barest minimum, 45 FPS is ok, and 60 FPS is sufficient for fluid gameplay in many games.
The ASROck’s NUC’s 57 FPS at 1920×1080 makes it essential that I test a good range of games on the machine in this series.
I’ve also run glmark2.
