Intel Xe-LPG architecture delivers higher frequency and larger GPU configurations than Xe-LP
A major upgrade to Intel’s integrated graphics.

Each successive iteration of Intel’s integrated graphics undergoes a 2x scaling enhancement, and the new Xe-LPG architecture is no exception to this trend. Derived from the Alchemist architecture found in the Xe-HPG discrete gaming GPUs tailored for both desktop and laptop systems, the LPG architecture will fully leverage the design advantages it inherits.
These include a reduced minimum voltage requirement and an increased maximum frequency. Consequently, the Arc-based integrated graphics processing unit (iGPU) will deliver heightened efficiency with higher clock speeds, enabling gaming experiences at remarkably low power consumption levels, as low as 10 watts.

Notable upgrades are also present in the Xe-LPG Vector Engine, which now supports 1 FP64 operation per clock cycle and allows for concurrent processing of FP+INT/EM instructions. As Intel adopts the same design principles seen in the Xe-HPG architecture, they are introducing Xe-Cores specifically tailored for integrated graphics. In the upcoming Meteor Lake release, we can anticipate the incorporation of 8 Xe-Cores, 128 Vector Engines, 2 Geometry Pipelines, 8 Samplers, 4 Pixel Backends, and a new addition of 8 Ray Tracing Units—a configuration similar to what can be observed in the ACM-G11 GPU.

Naturally, Intel Xe-LPG will support all the same technologies as HPG, such as XeSS upscaling. The inclusion of ray tracing hardware acceleration through 8 dedicated cores will put Xe-LPG on pair with integrated RDNA3 solutions, potentially giving some companies a reason to consider Meteor Lake processors for next-generation handheld gaming devices. Intel shows its Meteor Lake GPU performing various tasks from 2.1x in Pixel Blend Rate to 6.6x scaling in Depth Test Rate over Xe-LPG (as found in Raptor Lake).

The Xe-LPG will debut with the first Meteor Lake CPU series under the Core Ultra lineup later this year. Intel will be disclosing more details on Meteor Lake’s CPU and NPU architectures later today.
