Intel Arrow Lake-H Laptop 128 EU “Xe-LPG+” & Arrow Lake-S Desktop 64 EU “Xe-LPG” iGPUs Tested

iGPUs of Intel's next-generation Arrow Lake-H Laptop & Arrow Lake-S Desktop CPUs, based on the Arc Alchemist architecture, have been tested.

Intel Arrow Lake-H Laptop & Arrow Lake-S Desktop CPUs Spotted With iGPUs Featuring 128 EUs & 64 EUs Based on Arc Alchemist Architecture

It is no mystery by now that Intel's next-gen Arrow Lake CPUs will be reusing the Arc Alchemist graphics architecture. The laptop chips, Arrow Lake-H, will be featuring the slightly updated Xe-LPG+ architecture known as Alchemist+ while the desktop chips, Arrow Lake-S, will be using the same Arc Alchemist architecture we got with Meteor Lake. This will be the second outing of the Alchemist Xe-LPG architecture on desktops since Meteor Lake-PS CPUs have already introduced them on the LGA 1851 socket.

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

The Arrow Lake-S Desktop CPU is comprised of 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 remembered that Arrow Lake-S CPUs will be the first real outing of the Arc iGPU architecture for mainstream desktop consumers. Intel hasn't had any CPUs out yet which utilize its modern-day GPU architectures while AMD has already released RDNA 3 to the masses with its Ryzen 8000G family for AM5 desktop platforms.

So coming to the performance figures, the Intel Arrow Lake-S Desktop CPU scored 1053.56 Mpix/s in the GP(GPU) Processing benchmark in SiSoftware Sandra while the Arrow Lake-H Laptop CPU scored 1598.22 Mpix/s. The desktop chip has
