AMD Strix Halo does not have on-package RAM. What makes it stand out from other x86 SoCs is that it has more memory channels, for a total of a 256-bit wide bus compared to 128-bit wide for all other recent consumer x86 processors.

Qualcomm's laptop chips thus far have also not had on-package RAM. They have announced that the top model from their upcoming Snapdragon X2 family will have a 192-bit wide memory bus, but the rest will still have a 128-bit memory bus.

Intel Lunar Lake did have on-package RAM, running at 8533 MT/s. This new Panther Lake family from Intel will run at 9600 MT/s for some of the configurations, with off-package RAM. All still with a 128-bit memory bus.
