Moving to quad channel would mitigate any memory bandwidth concerns.
It kinda seems like things are getting a bit silly on the core counts though. Don't you think? Sure, for DC and Workstation, more cores please.
Honestly, I think desktop would be great with 32 cores. It would allow AMD to resolve the odd HEDT problem that Threadripper has.
Example:
Athlon - Dual channel memory - Up to 8 cores -20 PCIE 4.0 lanes
Ryzen - Quad Channel Memory - 8 - 32 cores - 40 PCIE 5.0 lanes (example prices: $1299 32c, $999 24c, $699 16c, X3D +$100)
Threadripper - 8 channel memory - 32+ cores - 80 PCIE 5.0 lanes
EPYC - 12+ Channel memory 32+ cores 80+ PCIE lanes.
Of course it probably won’t ever happen, but one can dream. 🤣
My old Zen 1 Threadripper had quad channel boards for $300-$500. While that was DDR4 and before inflation, I imagine they could get it done for $600-$800. The X chipset could be quad channel while the B chipset could be dual channel. The A chipset could be similar to B except designed for Athlon.
