AMD Zen 6 CPUs Reportedly Based On 2nm Process Node
A supposedly AMD engineer’s LinkedIn profile has revealed the codename and compute node of AMD’s distant Zen 6 processors. Zen 5, which ought to launch in 2024, is the following microarchitecture proper as much as the bat, so there’s nonetheless an extended strategy to go earlier than we see any renders of Zen 6.
New info comes courtesy of Md Zaheer (opens in new tab)He seems to be a senior silicon design engineer at AMD engaged on the facility administration facet of the Zen 4, Zen 5 and Zen 6 processors. The particular person has since hidden the names of AMD tasks he has been engaged on, however Twitter person Maraux David (opens in new tab) took a screenshot of the unique description earlier than the modifications. Admittedly, this isn’t a giant mistake as AMD has already revealed some particulars in regards to the Zen 5. Nonetheless, it does present some details about Zen 6.
You will not discover Zen 6 on official AMD roadmaps, because the chipmaker solely shares its plans for as much as Zen 5. The ultimate roadmap to June 2022 confirmed that AMD expects to launch Zen 5 in 2024. The Zen 6 in all probability will not attain the retail market till 2025, not a lot later. In response to Zaheer, who began engaged on Zen 6 in early 2023, the interior codename of AMD’s Zen 6 cores is Morpheus. The writer didn’t share the codename of the CCD (core advanced sample), although. Zen 6 chips are reportedly making use of the 2nm manufacturing course of. Nonetheless, we’re not positive if AMD will proceed to make use of TSMC for CCD manufacturing or if it has jumped on Samsung. Each TSMC and Samsung count on 2nm course of nodes to be prepared by 2025.
AMD Micro Architectures

|nigga 2||vahalla||Aspen Highlands||TSMC 7nm||2019|

The silicon engineer apparently labored on Zen 5 from January 2021 to December 2022, so in keeping with AMD’s roadmap, it seems like Zen 5 is heading in the right direction for the 2024 launch. The commerce identify of the Zen 5 processors is unknown, however AMD calls the mainstream chips Granite Ridge. Due to Zaheer, we now know that Zen 5 cores are recognized internally as Nirvana, whereas CCD (through Andreas Shilling (opens in new tab)) is codenamed Eldora.
AMD has beforehand acknowledged that it’ll use an “superior node” for Zen 5, which we estimate may very well be 4nm or 3nm. In response to Zaheer’s earlier notes, the Zen 5 will include a 3nm furnace. It is vital to emphasise that he’s a part of the server chips growth workforce, which might be EPYC. There are some rumors that the Zen 5 could also be out there in 4nm and 3nm variants.
AMD will use the Zen 5 microarchitecture to its fullest. Zen 5 might be launched on Granite Ridge for the principle market and EPYC Turin for servers. For Zen 5, AMD can even launch Zen 5c core chips which can be theoretically much like the E-cores present in Intel’s mainstream thirteenth Gen Raptor Lake processors. We can even see Zen 5 in Strix Level, AMD’s new APUs with RDNA 3+ graphics and an Synthetic Intelligence Engine (AIE).
Assuming Zen 5 follows an identical tempo because the earlier Zen microarchitecture, the primary client desktop Ryzen chips will seemingly hit the market within the second half of 2024. 3D V-Cache-equipped counterparts will arrive in a couple of months.
