At the beginning of November last year, Intel officially released a new discrete graphics card based on the Xe LP architecture. The first product is codenamed DG1, and the model is named Iris Xe MAX. It is aimed at the entry-level notebook and desktop market and has also extended to the field of media servers.
Of course, the core graphics cards integrated with Tiger Lake and Rocket Lake 11th generation Core are also based on the same architecture and similar specifications.
This is also the short-lived i740 in 1998 and Larrabee's failure in 2008. Intel first appeared in the discrete graphics market with a new look. NVIDIA and AMD finally ushered in new rivals.
At the time of its release, Intel stated that the Iris Xe discrete graphics card has a mobile version and a desktop version. Notebooks from Acer, Asus, Dell, etc. are already equipped with a mobile version. The desktop version will be available in early 2021, but only for the OEM market.
Intel today announced that the desktop version of the Iris Xe discrete graphics card has been officially shipped. The first release includes ASUS and Colorful products, which are only used for OEM machines and will not be retail.
Among them, ASUS has a passive mute design, covering a large area of the aluminum heat sink on the front, and a DVI, an HDMI, and a DisplayPort on the back.
Colorful uses dual fans (a bit exaggerated), the interface is not clear but should be the same.
The core specifications of the desktop version of the Iris Xe discrete graphics card are almost the same as the mobile version and the nuclear display version. They are all manufactured in a 10nm SuperFin process, with a maximum of 96 execution units (768 stream processors), 48 texture units, and 24 ROP units. With a 128-bit wide 4GB LPDDR4X independent video memory, the bandwidth is 68GB/s, and it supports PCIe 4.0 x4.
Of course, the frequency and power consumption are not the same. The official data is 1.35GHz for the mobile version and 1.65GHz for the desktop version. The non-official data says the power consumption is 25W and 30W respectively.
But the strange thing is that the mobile version of Iris Xe has a nominal maximum of 96 units, that is, there is a low-end version. When the desktop version was first released, the official made it clear that there were only 96 units. As a result, the first batch of goods was castrated with 80 units Version”, that is, 1/6 of the core unit is blocked.
The reason is not clear, but considering that even the full-blood version of the Iris Xe discrete graphics performance is only entry-level, it is even more difficult to imagine.
Intel also emphasized some of the features of the card, including three-screen output, hardware-accelerated video codec (including AV1 decoding), Adaptive-Sync adaptive synchronization, DisplayHDR, DP4a deep learning inference acceleration, etc.
