    Good to see any type of innovation . This actaly makes sense , i wonder why Intel did't came up with that before , doesnnt seem very complicated to introduce.

    Sounds like an intersting upgrade.

    Intel has its own 3D stacking method, announced in the past.

    Every one seems to be getting into stacking. Seems to work well for all applications, Camera sensors etcetera.

    so is AMD gonna change the series naming for this, is it gonna be Ryzen 6000 series or will it be Ryzen 5000 XT (or something)?

    Zen 4 will be 6xxx
    Zen3+ will be APU 5xxx

    They did kinda with Broadwell-DT chips, that featured 128MB of EDRAM, that when not used for graphics acted as an L4 cache for the cpu. It showed a significant performance increase in games when used as a cache. I'm not sure why they didn't pursue it further.

    Lisa said 3d stacked CPUs at the end of the year, Zen 4 in 2022.
    So who knows. Warhol supposed to be the refreshed Zen3 for 2021 as 6000 series, and 7000 series the Zen4.
    Who knows. We shall see.

    AMD glued together 2 dies. Now glued on top a ram module, literally if you see the video :D

    This^^ The concept was good and eveybody praised it but Intel considered the added EDRAM too expensive and removed it from newer models...

    As long it improves performance they can glue whatever they want. :p

    I dont see it hits the market until zen4.

    I'm wary of this trend of increasingly huge caches. A bigger cache has more bandwidth but worse latency. We're reaching a point where we basically just have on-die RAM. The APUs need the bandwidth, but even then, a few dozen MB here and there isn't enough when you consider how big textures are getting.


    It's crazy because back then, Intel was raking in around $11 billion in net revenue, when AMD was taking losses. In either case, if Intel were that concerned about the price, couldn't they just simply make it more expensive?
    The other crazy thing about it is Intel had very competitive performance with their iGPUs, simply because of that cache. Intel could have made a decent dent in the dGPU market years ago. It's almost as though they're trying to shoot themselves in the foot...

    A textbook case of Intel´s greed, where they simply choose to can a good product with tons of potencial, only to milk customers a few more cents...

    This works when they are the only player in town but when someone else appears...

    Well that's the part I find so confusing: they could have charged whatever they wanted for those Broadwells, and now is a better time than ever for them to explode their cache size (now that they're no longer #1), yet they don't.

    Thats because eDRAM is pretty expensive in such small capacities (it needs additional fabrication steps, etc). SRAM is cheaper to produce for such small capacities, but it needs much more space - and stacking is one way to overcome the space issues.

    Once you make the modules large enough, DRAM gets cheaper again due to the much higher density, but we're talking about 2x 64MB here for AMD (plus the 64MB already in-die)

    This is much more interesting than blurry upscaling technologies. Bring on the real performance improvements. Putting this in an AM4 socket CPU would tempt me to upgrade the 3900X.

    Imagine next Radeon with a giant cache on top of it that can handle 8K textures with ease... :eek:

    I'm genuinely surprised tbh. Everything about this makes it sound like it's going to be an AM4 CPU. I honestly didn't expect them to waste time on a Zen 3 refresh. Not complaining, I might actually give it a punt if the price is right, just surprised.
