We could look at this a different way, though, as Intel's Xe DG1 graphics card basically used the same Xe-LP configuration as the integrated chips. The mobile Iris Xe meanwhile clocked at up to 1.5 GHz in chips like the Core i9-13905H, with a maximum TDP for the entire package of just 45W. That GPU runs at up to 2.4 GHz, but it also consumes up to 75W of power. Intel hasn't provided clock speeds or the L2 cache size yet, but in general we'd expect more conservative clocks than what you'll get from a dedicated A380. As you'd expect from an integrated solution, the Meteor Lake GPU will share system memory with the CPU. Nearly everything present in the A380 appears to be here as well, other than GDDR6 memory controllers and XMX units (more on the latter below). ![]() If the above diagram looks familiar on some of the details, that's because it's effectively the same as the ACM-G11 GPU that's used in the Intel Arc A380 - only now it's an integrated graphics solution. These will be divided up between the two Render Slices, the main building block for Intel Arc GPUs. The block diagram for Xe-LPG shows the maximum configuration, which will come with eight Xe-Cores, 128 Vector Engines (formerly called Execution Units), two Geometry Pipelines, eight Samplers, four Pixel Backends, and eight Ray Tracing Units. We'd expect Intel to disable some of the GPU processing clusters and perhaps some of the other extra features on lesser parts, while the Core 5/7/9 chips will offer the complete feature set. Note also that the highest configurations won't be available on all Meteor Lake processors, though the exact details of the lower tier models haven't been revealed. It's potentially double the performance of Xe LP, which was the graphics solution used in the 11th Gen Tiger Lake, 12th Gen Alder Lake, and 13th Gen Raptor Lake mobile solutions. ![]() The new graphics architecture is called Xe-LPG, the low power gaming alternative to Xe-HPG - that's the GPU found in the dedicated Intel Arc Alchemist GPUs. That's a potentially huge gen-over-gen improvement, and there's plenty of other details to dissect. While GPUs often lay claim to efficiency improvements, given how power constrained mobile graphics solutions can get, there's a real possibility we could see raw performance double as well. Skipping all of the architectural details for a moment, Intel claims the Meteor Lake GPU will double the performance per watt of its previous generation Iris Xe Graphics solution, which was found in 12th Gen Intel Core processors.
