![]() ‘There will be more core counts in the future – I would not say those are the limits! It will come as we scale the rest of the system.’ĪMD's Rick Bergman on Next-Gen Zen 4 Cores For Ryzen CPUs We are as good as we are with the product today, but with our ambitious roadmaps, we are focusing on Zen 4 and Zen 5 to be extremely competitive. ‘Mark, Mike, and the teams have done a phenomenal job. The brand new Zen 4 architecture is rumored to deliver up to 25% IPC gain over Zen 3 and hit clock speeds of around 5 GHz. Support on AM5 Platform With LGA1718 Socket.Brand New TSMC 5nm process node with 6nm IOD.Brand New Zen 4 CPU Cores (IPC / Architectural Improvements).AMD has hinted at upping the core counts of its next-gen mainstream desktop CPUs so we can expect a slight bump from the current max of 16 cores and 32 threads.ĪMD Ryzen Raphael 'Zen 4' Desktop CPU Expected Features: ![]() From the information we currently have, Raphael CPUs will be based on the 5nm Zen 4 core architecture & will feature 6nm I/O dies in a chiplet design. The next-generation Zen 4 based Ryzen Desktop CPUs will be codenamed Raphael and will replace the Zen 3 based Ryzen 5000 Desktop CPUs that are codenamed, Vermeer. ![]() Here's Everything We Know About AMD's Raphael Ryzen 'Zen 4' Desktop CPUs The specifications for the CCD will be similar but we will see some major cache design upgrades through the use of 3D V-Cache & much higher TDPs. We know that Zen 4 isn't coming to the AM4 platform and AM5 is the next big upgrade for AMD. So once again, these slides are really old and a lot has changed. There's also a slide that shows the Zen 4 'Raphael' SOC for AM4 with dual-channel DDR4 memory support and features that look a lot similar to an APU rather than a mainstream CPU. The slide lists down 4 channel (128-bit) DDR5 and DDR4 memory support but we know that only dual-channel DDR5 is happening with Raphael. The AMD Ryzen 'Raphael' Zen 4 Desktop CPU CCDs will be connected to the IOD through the Infinity Fabric bus. Moving on, we have the AM5 platform block diagram which shows the CIOD3 (I/O die) in detail. ![]() Interestingly, there's no mention of the Zen 3 products launching early next year or the 3D V-Cache stack chiplet design which has been confirmed earlier this week at Computex. ![]() It is very interesting that we see the mention of Warhol and if (and I mean a big if) these slides are indeed real from some point in AMD's timeline, then it shows that it was something that AMD was (or is still) working on. In terms of CPU performance, the Zen 4 chips are stated to offer performance uplift when compared to Warhol on the same TDP. It is stated to offer entry-level desktop graphics performance. There's also an AMD RDNA 2 based integrated GPU onboard the Ryzen Raphael Desktop CPUs. The Zen 4 CCD is codenamed Durango and features 8 cores, 16 threads, and 32 MB of 元 cache with 2-Way SMT support.ĪMD Ryzen 'Raphael' Zen 4 Desktop CPU Leaked Slides From Early 2020 (Credits: Gamers Nexus): In terms of technology, Zen 4 chips are stated to feature two Zen 4 CCD's based on the TSMC N5 process node and a CIOD (I/O die) based on the TSMC N7 process node however the latest reports suggest that the I/O die has been moved to a 6 nm process node. We have seen the new package design for both AMD Ryzen Zen 4 Desktop CPUs and the LGA 1718 socket already. Moving on, the slide talks about an upgraded AM5 platform with more IO & more current delivery which honestly is nothing new. ![]()
