The UHD Graphics G1 is a mobile integrated graphics solution by Intel, launched in May 2019. Built on the 10 nm+ process, and based on the Ice Lake GT1 graphics processor, the device supports DirectX 12. This ensures that all modern games will run on UHD Graphics G1. Unlike the fully unlocked Iris Plus Graphics G4, which uses the same GPU but has all 384 shaders enabled, Intel has disabled some shading units on the UHD Graphics G1 to reach the product's target shader count. It features 256 shading units, 16 texture mapping units, and 8 ROPs. The GPU is operating at a frequency of 300 MHz, which can be boosted up to 900 MHz.
Its power draw is rated at 15 W maximum. UHD Graphics G1 is connected to the rest of the system using a PCI-Express 3.0 x1 interface.
