Intel Razor Lake-AX to use on-package memory with a large GPU

Intel to return to on-package memory with Razor Lake-AX – Leaker claims

Intel’s long-rumoured Razor Lake-AX processor is shaping up to be a fascinating piece of silicon. This processor reportedly combines next-generation (post-Nova Lake) CPU cores with a powerful ARC integrated graphics solution (iGPU). Now, according to the leaker Haze2K1, Intel has chosen to pair this CPU with on-package memory. This makes Razor Lake similar to Intel’s last-generation Lunar Lake CPUs.

It is currently unknown why this CPU will use on-package memory. That said, competing Apple Silicon products all use on-package memory. While this makes after-purchase memory upgrades impossible, it makes using high-speed memory easier, as maintaining signal quality is easier when memory is on-package. It also makes product design easier, as memory and compute are packaged together. This is a big deal for products with a lot of memory and a wide memory bus.

As hinted at before, Razor Lake-AX is a product that will compete with Apple Silicon and AMD’s Strix Halo successor. This processor should feature many CPU cores, an NPU, and a powerful integrated graphics solution. This GPU should be much later than what’s available on today’s Panther Lake series CPUs.

Intel moved away from on-package memory with Panther Lake. Lunar Lake used on-package memory, but Intel found that the increased flexibility of off-package memory was a worthwhile trade-off with Panther Lake. With Razor Lake-AX, we expect Intel to use a wider memory bus and target higher-speed DRAM speeds. With this in mind, using on-package memory makes a lot of sense, even if it limits upgradability.
