AMD Unveils New Ryzen V-Cache Details at HotChips 33:

AMD gave us more information about its upcoming V-Cache at Hot Chips this year, the annual conference where semiconductor engineers from all over the industry come together to crow over disclose details regarding their technical achievements in the past 12 months.

Earlier this year, AMD announced that it would not advance directly from Zen 3 to Zen 4. Instead, it would iterate on the Zen 3 core by stacking a full 64MB of 7nm L3 cache vertically on the core. AMD claims this can improve performance by up to 15 percent based on 1080p gaming results. The improvement in other applications is unknown.

    Face it, it doesn't matter at all how good, fast or powerful your chip is if it's essentially unobtanium. Try to solve the supply crisis first before announcing some wonder chips, nobody gives a fuck about it unless we can actually buy it without paying a fortune to scalpers.

    Ryzen 5000 series CPUs were hard to get for a while, but never as bad as GPUs and now we're seeing frequent price cuts to below MSRP, not counting Micro Center:

    AMD Ryzen 5 5600X 3.7GHz 6-Core AM4 Processor @Newegg $268 [slickdeals.net]
    AMD Ryzen 7 5800X 8-core, 16-Thread Unlocked Desktop Processor $396.99 at Amazon [slickdeals.net]
    AMD - Ryzen 9 5900X 4th Gen 12-core, 24-threads $499.99 BestBuy Amazon [slickdeals.net]
    AMD Ryzen 9 5950X 16-Core 32-Thread Desktop Processor $739 + Free Shipping [slickdeals.net]

    There's nothing AMD can do immediately to solve a supply crisis, since capacity agreements are made months or years in advance. It looks like they might backport Zen 3 and RDNA 2 onto GlobalFoundries 12nm+ for budget APUs ("Monet"), and for their 7000 series GPUs they can make RDNA 3 on TSMC N5 and refreshed RDNA 2 on TSMC N6 at the same time.

    People obviously care about these chips. Scalping would not last long if nobody paid the scalpers.

      My work has been trying to buy servers for a server refresh project ever since the EPYC 73F3 was announced for general availability. Our last update from the vendor is, "some time in December". 16 and 24 core are available now, though. We ended up pre-ordering to (hopefully) ensure our place in line.

      * 32 core high frequency due to optimizing for software license policies.
