Sadly there's no alternative if you want 256 bits wide at the moment. Well a previous generation threadripper with a huge increase in power consumption and requiring a discrete GPU.

BTW, careful with "channels". Todays normal desktops and laptops (besides the strix halo and apple pro/max/ultra) are 128 bits wide. But in the DDR4 -> DDR5 transition they doubled the number of channels to 4. However the strix halo biggest advantage is the extra memory bandwidth going from 128 bits wide to 256 bits wide.

Finally the technology of the ps5 and XboxX comes to laptops, tablets, and small desktops.
