Intel has recently integrated initial support for its 15th Gen Arrow Lake processors into the Intel Graphics Compiler. The upcoming Arrow Lake processors, much like the previously announced Meteor Lake, will feature a chiplet design with a disaggregated iGPU tile fabbed on TSMC’s N4 (4nm) or N3 (3nm) process node.
The 15th Gen family will utilize the Xe-LPG Plus architecture, which is a modified version of the Xe-LPG GPUs used by Meteor Lake. This new graphics architecture combines the features of Xe-LP and Xe-HPG to provide a low-power architecture for mild gaming with most DX12 capabilities.
One of the primary differences between the Xe-LPG GPU on Meteor Lake and the Xe-LPG Plus on 15th Gen Arrow Lake is the incorporation of XMX units. The XMX units, which take up significant die space, are notably absent from the former but have been added for the 15th Gen. The addition of XMX units provides a notable advantage for mobility platforms where every frame and watt count.
Intel’s Xe-LPG iGPUs also include dedicated ray-tracing hardware capable of BVH traversal, ray/box intersection testing, and thread sorting to reduce divergence and improve utilization. This makes the LPG’s RT Cores on par with AMD’s RDNA 3 Ray Accelerators in terms of features.

With this initial support for 15th Gen Arrow Lake processors, Intel continues to advance its offerings in the gaming and technology industries. Stay tuned for further developments as Intel prepares to launch its new processors in the near future.
