Is AMD's 16-core 'Zen' processor real? Leaked slide provides details on stout chipBy Shawn Knight 36 comments
AMD is poised to make quite a comeback if a leaked slide proves accurate. The slide in question details AMD's Zen core APU and Greenland HBM memory-powered graphics and arrives courtesy of Fudzilla.
Specifically, the slide is for a chip that'd contain up to 16 Zen x86 cores with support for 32 threads (two threads per core), a structure that Intel has been using to great effect for years now. Each core will have access to 512KB of L2 cache while each cluster (a group of four cores) will share 8MB of L3 cache.
In this specific instance of a 16-core chip, we're looking at a total of 8MB of L2 cache and a hefty 32MB of L3 cache.
We also learn that the platform will employ secure boot and crypto coprocessor, both of which are valuable to corporate clients. Elsewhere, users can expect Greenland Graphics and up to 16GB of HBM (high bandwidth memory) at 512GB/sec that comes with ½ rate double precision compute, enhanced ECC and RAS as well as HSA support.
In terms of RAM, the slide promises quad-channel DDR4 support with ECC up to 3,200MHz. There's also support for up to 256GB of memory per channel which is a ton of memory.
We'll keep our fingers crossed that this is indeed a legitimate slide. After all, competition is good for the entire industry... well, for everyone except Intel. Given the specs, however, not everyone is convinced this is the real deal. Your thoughts?
