A report by Chinese technology outlet, UDN, suggests that AMD's Zen 5 CPUs will be entering TSMC fabs in Q2 followed by mass production in Q3 2024.
The Zen 5 CPU architecture is going to be a big deal for AMD in 2024 as it will power multiple lines of CPU families including Granite Ridge "Ryzen Desktop", Strix Point "Ryzen Mobile" & Turin "EPYC Server". All of these CPU families will play a major role and it looks like these chips are entering the TSMC fabs for production next quarter followed by volume production in Q3 2024, as reported by UDN.
The outlet also specifically points out the AMD Zen 5 "Nirvana" CPU core which is the standard Zen 5 architecture design while the "Prometheus" Zen 5C cores will aim the dense-compute segment in client and server chips. Interestingly, the Zen 5 "Nirvana" CCD is mentioned to be produced on the TSMC 3nm process node however we know from previous reports that Zen 5 will be using the 4nm node while Zen 5C will be made using the 3nm process.
It might be possible that UDN has confused the Zen 5C "Prometheus" core with Zen 5 "Nirvana". It was just last month when it was rumored that AMD's Zen 5 "Granite Ridge" CPUs had already entered the mass production stage though the company hasn't revealed anything about its next-gen desktop CPU plans at major events such as CES 2024. The only upcoming event that we can think of for an unveil would be Computex 2024 which will be held in June so that's still four months to go.
Not a whole lot about AMD's Zen 5 core architecture is known at the moment but from what the company has officially stated, it will offer:
