Intel's next-generation iGPUs Aero Lake-H Laptop And Arrow Lake S Desktop CPUs based on Arch Alchemist architecture have been tested.

The Intel AeroLake-H laptop and AeroLake-S desktop CPUs are spotted with iGPUs that include 128 EUs and 64 EUs based on the Archchemist architecture.

By now it's no mystery that Intel's next-generation Aero Lake CPUs will reuse the Archchemist graphics architecture. The laptop will feature chips, Arrow Lake-H. A slightly updated Xe-LPG+ architecture called Alchemist+. While the desktop chips, Arrow Lake-S, will use the same Archchemist architecture we found with Meteor Lake. This will be the second outing of the Alchemist Xe-LPG architecture on desktops as Meteor Lake-PS CPUs have already introduced them on the LGA 1851 socket.

With that said, today's leak gives us a look at two laptop and desktop iGPUs. Starting with the Arrow Lake-H CPU, we're looking at an 8 Xe-Core iGPU with 128 execution units, a clock speed of 2.00 GHz, and 8 MB of L2 cache. The chip was running on a reference evaluation platform with DDR5 memory.

The Arrow Lake-S desktop CPU features 4 Xe-cores for a total of 64 execution units, 4 MB of L2 cache, and the same 2.00 GHz clock speed. The chip was running on an evaluation board with a pair of DDR5 UDIMMs. Now it should be noted that the Arrow Lake-S CPUs will be the first real outing of the Arch IGPU architecture for mainstream desktop users. Intel does not yet have a CPU that uses its modern GPU architectures while AMD has already released RDNA 3 to the public. Ryzen 8000G family for AM5 desktop platforms.

So coming to the performance data, the Intel Arrow Lake-S Desktop CPU scored 1053.56 Mpix/s in SiSoftware Sandra's GP(GPU) processing benchmark while the Arrow Lake-H Laptop CPU scored 1598.22 Mpix/s. The desktop chip has half the number of cores but runs at a higher TDP of 65W (PL1) compared to the laptop chip's 45W (PL1).

So you're looking at about a 50% difference between the two chips as expected. These numbers are not definitive as driver optimization on the road can further improve performance. The good thing is that we have already seen. Lunar Lake CPUs with Battlemage “Xe2-LPG” iGPUs appear in previous leaks And we can use those and other Intel iGPUs for comparison:

Intel Arrow Lake-H CPUs with 128 EU iGPUs appear to be sitting ahead of the Arc A310, an entry-level Alchemist-based discrete graphics card, while the desktop Arrow Lake-S CPU tops the Meteor Lake 64 by about 15%. It's ahead. EU SKUs. It's a good performance benchmark for the Arrow Lake desktop and mobility family and shows that Intel can go a long way before switching to its current Arc Alchemist and optimized Alchemist+ iGPUs. The next generation Xe2 “Battlemage“And Xe3 “Celestial” chips For the mainstream public.
