16 PCWorld DECEMBER 2020NEWS INTEL’S IRIS XE MAX GPU
LPDDR4x.
First, the numbers. Intel’s original Tiger
Lake product matrix listed the graphics
frequency, which you can find listed in the
tables below. The Iris Xe Max GPU is a version
of the Tiger Lake-LP GPU, but running at a
faster 1.65GHz. There are 96 EUs inside the
Iris Xe Max, too. The similarities between the
Tiger Lake GPU carry over to the memory:
Instead of the GDDR memory you might
expect, the Iris Xe Max addresses just 4GB of
LPDDR4x memory, the same memory type as
Tiger Lake.
While the Intel Iris Xe Max gets to its
higher frequencies using different libraries
than Tiger Lake, “there are a lot of similarities
to Tiger Lake,” according to Josh Moss, a
member of the graphics product marketingteam for Intel’s Client Computing Group.
Here are the full technical specifications
for the Iris Xe Max. Note that it shares other
common features with the Tiger Lake family:
PCI Express 4.0, for one, as well as the ability
to connect to up to four displays, with up to
8K support over DisplayPort.
