First of all, let’s take off the cast light alloy cover, and we see the 8 cm PWM fan with the 9 rotor blades, which manages decent throughput if it’s just allowed to spin fast (and loud) enough. The PCB is covered with a string cooler made of aluminum, but the whole voltage transformers are not included in the cooling. However, with these low power losses, this can certainly still be tolerated.
Now let’s look at the circuit board. The GPU is powered by a full 2 phases, implemented via a simple buck controller and one PowerStage per phase. Power is supplied exclusively via the motherboard slot (PEG). We see the four frugal LPDDR4 modules from Micron with a size of 2 GB each and of course the Intel-typical package with the almost tiny Xe-GPU in the middle. Beside the many smaller buck controllers for other low voltages you can see the controller chip next to the PWM connector for the fan.
The back is unexciting and almost empty. The MLCC orgy of high-performance graphics cards below the BGA fails completely here. We still recognize the single BIOS and a control port. But that’s about it.
Intel advertises the great connectivity of the Xe products and the DG1 also comes with three current DisplayPorts and an HDMI 2.1 port. However, this also shows the problem of our test system, because Intel explicitly pointed out that the monitor has to be connected to the motherboard port of the iGP. With a bit of luck, you still get a picture on the HDMI, but the system is no longer stable. Here firmware and drivers probably still interfere with the direct connection. This part also looks completely unfinished, unfortunately.
