Intel appears to have developed a couple of desktop graphics cards that have the company’s Iris Xe DG1 GPU. These graphics cores are present as embedded solutions for Intel’s 11th-Gen Mobile Processors. However, with the introduction of these Graphics Cards, Intel has firmly entered the Desktop Graphics Card arena.
Intel Iris Xe DG1 Desktop-grade Graphics Cards are here. The company has officially launched these GPUs for desktop computing. But end-consumers, who wish to have a third alternative to NVIDIA and AMD Graphics Cards, will not get the opportunity. Intel is currently restricting the availability of the Iris Xe DG1 Desktop Graphics Cards to OEMs and system integrators only.
Intel Iris Xe DG1 Desktop-grade Graphics Cards Similar To Their Mobile dGPU Solutions?
Intel hasn’t made the Iris Xe DG1 Desktop-grade Graphics Cards much different from the Mobile dGPU. In fact, these Graphics Cards appear to have the same GPU core from the first generation of Xe DG1 GPU. Just like the current Iris Xe products, the Iris Xe for the desktop is based on the Xe-LP architecture. In other words, Intel has prioritized these dedicated desktop graphics cards for economy and efficiency.
Currently, the Intel Xe LP Architecture is present in an integrated form-factor within the Tiger Lake processors. There are two variants of the dGPU. One has 80 Execution Units and the other has 96 EUs. The Intel Core i7-1185G7 with Iris-Xe graphics has 96 EUs at a clock rate of 1.35 GHz.

Early benchmarks indicate the Intel Iris Xe offers double the performance of the previous Intel Iris Gen10 Graphics solutions. However, the dGPU doesn’t have its own VRAM. Instead, the integrated variant uses the main memory as graphics memory.
The Intel Iris Xe MAX variant has 96 Execution Units. It sports a clock speed of 1.65 GHz. Moreover, it has 4 GB of LPDDR4X memory available as dedicated memory. The VRAM is connected via a 128-bit memory interface and has a memory bandwidth of 68 Gbps.

Incidentally, the dedicated solution for the desktop only packs 80 Execution Units. The Clock Speed, however, should be higher. This is because the Intel Iris Xe DG1 Desktop-grade Graphics Cards seem to have a 30W TDP Profile, while the mobile dGPU has a 25W TDP Profile.

Intel’s dedicated desktop graphics cards, based on the Xe LP Architecture, support Variable Rate Shading, Adaptive-Sync, and Async Compute. There’s also AV1 Codec support. These Graphics Cards have a Display Port of the eDP variant which supports 1.4b standard, DisplayPort 1.4, and HDMI 2.0b. These Graphics Cards support a maximum resolution of 4,096 x 2,304 at 60 Hz via HDMI and eDP as well as 7,680 x 4,320 pixels at 60 Hz via DisplayPort.
While one of the variants is completely passive cooled, the other Intel Graphic Cards has active cooling. The passively cooled version of ASUS (DG1-4G) has HDMI, DisplayPort, and dual-link DVI. The actively cooled iteration is made by Colorful, and it has two axial fans. It is quite likely that the company has placed two fans for cosmetic effect as the 30W TDP Graphics Card doesn’t need such high power cooling.
