Leaked Email Suggests AMD Instinct MI450 Accelerators to Feature XSwitch Interconnect Fabric

[T0@st]

AMD is reported to be forming plans for its Instinct MI400 Accelerator series, according to a leaked internal email. This information was shared by a hardware tipster (HXL/@9550Pro) on Twitter, but their post has been deleted as some point today. Wccftech was quick enough to note down the details, and their report suggests that AMD is already making plans for an APU range that is set to succeed the unreleased Instinct MI300 lineup (expected later in 2023). Instinct MI400 accelerators are touted to drive next generation data center and cloud platforms.

The leaked email email contained information about three upcoming products: Weisshorn, MI450 and XSwitch. Kepler's recent tweet posits that Weisshorn is AMD's in-house moniker for Zen 6 "Morpheus" architecture-based Venice CPUs - these are alleged to form part of an upcoming EPYC lineup (slated for 2025 or 2026). Hardware experts reckon that AMD will introduce a new interconnect fabric with the MI400 series - "XSwitch" is speculated to be the company's main technological answer to NVIDIA's NVLINK.

Interesting.

I'm guessing this is kinda like a conceptual-hybridization of CXL and InfinityFabric/HyperTransport?

AMD almost has double the market valuation as Intel ($205B vs $120B). Clearly the world thinks that Intel is in big trouble. What will you do when you can no longer buy an Intel CPU?
