*** AMD "Zen 4" thread (inc AM5/APU discussion) ***

I wonder if it's a problem of scale, maybe they aren't going to produce that many x670 /x670E boards, relative to B650/B650E boards?

They use the same chipset, but doubled up for x670.

AMD is probably limiting how many x670 boards are produced, to keep prices high.

It's 'early adopter tax ' .There's always peeps out there who will buy new and price won't be an issue.

They just want the 'new'.

Soon there will be cheaper boards.

This diagram explains really well what you get from a 2nd Promontory 21 chip, in addition to a single chip:

• M2 NVME X4 PCIe v4 slot
• x4 Sata III ports
• 2 20Gbps USB type C ports
• 4 10Gbps USB standard type ports
• 4 USB 2.0 ports

It does sort of look like the X670 chipset is not worth it, especially since everyone gets the same number of PCIE5 slots for graphics and NVME drives.

Maybe worth it if you want a lot of usb ports, it's also possible that there won't be any B650/B650E boards that support USB 4 (v1).

A far cry from the $125 we were told then?
Obviously we don't know how much boards from other companies will cost. ASRock is likely to offer some cheap (but not necessarily good) boards. I wonder if there will be boards with no wifi?

Yeah those prices are still significantly higher than equivalent Intel b660 prices

For example

MSI B660m-A: $125USD (works with Raptor lake and you can buy it today)

MSI B650m-A: $199USD (needed for Zen 4)

if I was planning on keeping system for good number of few years personally would prefer DDR5
Yeah, its a pretty obvious decision for a new platform. It would be a more difficult decision for AMD if Intel hadn't already adopted DDR5 on LGA1700.

People who complain about DDR5 prices are mostly people who already have 32GB of RAM installed in their PCs, which isn't very many people.

If going DDR5 now you need to spend almost £300 to get 32gb of anything decent vs half that for a decent set of b-die. The performance difference between either is negligible while the B-die will likely hold its value more for resale compared to today's top DDR5.
