    looks like this 3d vcache chip wont help much in windows 11, may help bring windows 10 style zen3 performance to windows 11 lol.

    The release will be too close to Zen 4 IMO. May as well just go for that as long as DDR5 is certainly better than DDR4 by then.

    Makes perfect sense, if you can put ddr5 into a ddr4 board.

    So, looks like Zen 3 Threadripper has been delayed again - I reckon they will launch with this stack design and that's the reason for the delay.

    Hopefully that's the case - wouldn't mind replacing my 3970X but bit annoying if its just basic Zen 3 after all this time while mainstream is getting 3D stack.

    How much cache do you think AMD will add to TR?

    They are derived from Milan X, ultimately those are the reason 3D stacked chips, the flagship is EPYC 7773X.

    96MB per chiplet, so
    8X 768MB.
    4X 384MB.
    2X 192MB.

    It's a standard 64MiB per chiplet, isn't it? So each chiplet has 96MiB cache in total, and multiply that up by however many chiplets in a TR SKU. So a 5990XT (for lack of a better name) would be 768MiB cache total (8 x 96Mib)

    My first PC came with 64MB ram and Windows98, how things have changed over the years.

    Will certainly be more expensive though. A decent B550 + fast RAM are quite cheap atm, even if you spend a lot on the CPU (i.e. 5900X/5950X w/ V-C), but chances are even if CPU prices are close to Zen 3 V-C the mobos & DDR5 will be double or more.

    It will be interesting to see how Intel’s IGP performs with DDR5.
