Gigabyte hack yields AMD Zen 4 details -- EPYC going 400W TDP?

Posted on Wednesday, Aug 18 2021 @ 11:36 CEST by Thomas De Maesschalck
Last week news hit the wire about Gigabyte being the victim of a 112GB hack. A lot of confidential data was stolen and some of this information has now been leaked on the internet. German tech site ComputerBase found several documents on Twitter that reportedly originate from the hack. Some of the tidbits confirm earlier rumors about AMD's server and enthusiast-class processors. At the moment, the information is already widely spread.

AMD Zen 4-based EPYC goes up to 96 core - max TDP of 400W?

ExtremeTech writes server chips based on the Zen 4 architecture will feature up to 96 cores, 12-channel DDR5-5200 memory support, and AVX-512 support. These "Genoa" processors will be made on a 5nm process. Genoa isn't launching anytime soon, before this generation we'll see Milan-X, an upgraded Zen 3 core with 64MB 3D V-Cache per chiplet, resulting in an extra 512MB of L3 cache.

Just like Intel, AMD seems to be exploring higher power targets. AMD's top server CPUs could see a configurable TDP of 320W to 400W!
The leak also shows that TDPs on Genoa servers will be headed upwards, from the current 280W to 320-400W for the top products. The 64-core 400W TDP variant shown above will presumably hit higher frequencies than the 96-core variant. Note that there’s an even higher 700W target that the CPU is allowed to hit for 1ms or less.

AMD Ryzen Threadripper 5000 "Chagall" sticks to 64 cores

VideoCardz writes the leak also confirms AMD is working on a new Ryzen Threadripper series. Codenamed "Chagall", the Ryzen Threadripper 5000 series will reportedly get up to 64 cores for the top model. That's the same as the current 3990X flagship.
According to the ‘Infrastructure Roadmap for sTRX4 and sWRTX8 Processors’, AMD will launch both the Workstation and High-End Desktop Zen3 Threadripper series. The table that lists thermal requirements for both platforms confirms that TDP ranges have not changed since Zen2, nor has the core count for the next-gen Threadripper series. The table confirms that the top SKU will be 64 cores.
And here we have the tweets from KittyYYuko:
