  erdekes lenne tudni, hogy van-e valami specialis cache-management megoldasa az AMD-nek, amivel a juzer tudja kicsit finomhangolni a mukodeset. igaz az Intel CAT(cache allocation technology) sem lett atuto siker. valoszinuleg a cache mennyisege miatt amugy sem lesz teleszemetelve, szoval nincs szukseg arra h eroltessem valami adat bentmaradasat. azert cache-en allokalni memoriat eleg utos lehetne

  van par erdekes info Junius 1-rol az anandtech oldalan:
  - This technology will be productized with 7nm Zen 3-based Ryzen processors. Nothing was said about EPYC.
  - Those processors will start production at the end of the year. No comment on availability, although Q1 2022 would fit into AMD's regular cadence.
  - This V-Cache chiplet is 64 MB of additional L3, with no stepped penalty on latency. The V-Cache is address striped with the normal L3 and can be powered down when not in use. The V-Cache sits on the same power plane as the regular L3.
  - The processor with V-Cache is the same z-height as current Zen 3 products - both the core chiplet and the V-Cache are thinned to have an equal z-height as the IOD die for seamless integration
  - As the V-Cache is built over the L3 cache on the main CCX, it doesn't sit over any of the hotspots created by the cores and so thermal considerations are less of an issue. The support silicon above the cores is designed to be thermally efficient.
  - The V-Cache is a single 64 MB die, and is relatively denser than the normal L3 because it uses SRAM-optimized libraries of TSMC's 7nm process, AMD knows that TSMC can do multiple stacked dies, however AMD is only talking about a 1-High stack at this time which it will bring to market.
