On top of a series of exciting announcements that included new Radeon RX 6000M Series mobile GPUs and FidelityFX Super Resolution, AMD CEO Dr. Lisa Su managed to leave one last surprise for audiences at the end of her Computex 2021 presentation with a first look at AMD’s next breakthrough: a specialized 3D chiplet and stacking technology that allows for over 200 times the interconnect density of traditional 2D chiplets. To demonstrate the progress of its new packaging solution, Su showed off a special Ryzen 9 5900X prototype chip leveraging a 3D V-Cache stack, which enables triple the amount of cache that its cores normally have access to (32 MB vs. 96 MB of L3 cache). First-party benchmarks aired by AMD suggest that the first Ryzen chips with 3D chiplets, scheduled for release by the end of this year, will offer 15 percent faster gaming on average at minimum.

Pioneered in close collaboration with TSMC, the industry-leading technology also consumes less energy than current 3D solutions and is the most flexible active-on-active silicon stacking technology in the world. […] AMD is on-track to begin production on future high-end computing products with 3D chiplets by the end of this year.

  1. So what do they hope to achieve with these? Not like you can buy a GPU to see any difference and by the time you get GPU’s they will be on a new architecture with their CPU’s too, well maybe they can leverage the tech there also but kind of useless now, if anything they should focus on non gaming stuff.

    PR.

    Really, there’s nothing special here; they’re demonstrating the fact that Zen 3 is still memory latency limited to the point that having >32MB of L3 cache can deliver another 15% of gaming performance.

    Stacked silicon is also nothing new, and it comes with manufacturing complications that can really throw a wrench in things, like HBM did for Vega.

  3. If they release 5900x Chips with 96mb of cache I’ll try and buy one. It will be the last am4 chip I own I am sure.

    That may be what Zen3+ brings to the table.

    Could be an interesting upgrade for zen 3 threadripper – an extra 256 of stacked L3 Cache on top of the normal 128(?)mb.
