Intel is providing an open source drivers for their integrated GFX 
chipsets that are integrated in to the main-line Linux kernel source.

This is the kernel documentation: 
https://www.kernel.org/doc/html/latest/gpu/i915.html
This is the official Intel website: https://01.org/linuxgraphics

Unfortunately they are using proprietary firmware. Guix by default is 
using the Linux-libre kernel which is stripping all these non-free BLOBs 
(at least some time ago when I last checked).

The official Intel firmware information page: 
https://01.org/linuxgraphics/downloads/firmware
The BLOBs living in the kernel source tree: 
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915

So to make the integrated card work with its full potential you will 
need to enable the usage of the binary firmware blobs. I'm not sure how 
well it will be working without the binary firmware BLOB. See for 
example this discussion:
