AMD Zen 4 Raphael processor’s IHS design for AM5/LGA1718 package leaked

AMD is set to bring its next-gen Zen 4 based Ryzen 7000 processors codenamed Raphael next year, and the increasing leaks are just confirming its specs every day.

ExecutableFix has again made a big leak of the IHS design for the AM5/LGA1718 package, and before the same leaker confirmed its existence, the AM5 socket would be based on LGA design. The leaker also previously leaked the AM5 LGA1718 package’s mockup and, now recently, the IHS design.

The leaker did reveal the futuristic CPU design for Raphael quite precisely, not the final, however gives fair idea. So, as per the leak, the integrated heat spreader ot IHS will not be having a uniform shape, however, each side will have two cutouts which still seams a peculiar move from AMD.


Previously, the leaker also confirmed that the new AMD Zen 4 Raphael processors would retain the size of the AM4 CPUs i.e. 40x40mm.

If we go by how much data we have about these upcoming CPUs, you will be glad to know that a lot of preliminary info has already been leaked. AMD’s Zen 4 based CPUs will use TSMC’s 5nm process node & the IOD will be based on TSMC’s 6nm process node. 

Zen 4 is now supposed to give around a 20% IPC increase over last year’s Zen 3, and this kind of jump is expected because of the leap in architecture. Not only this, the architecture will allow Zen 4 CPUs will feature 8 core chiplets, so expect around 50% performance per watt gains between Zen 3 and Zen 4.

Now, the support AVX-512 instructions on Zen 4 remains to be seen, especially on the desktop processors; however, server-based EPYC Genoa CPUs are expected to come with the feature. It is expected that AMD would still provide 16-core flagship mainstream desktop CPUs with Zen 4 based Raphael processors with an optional 24 core option, which would not be cheap.

Also, the presence of 28 PCIe Gen 4.0 lanes is now confirmed, and it also signifies, AMD would not shift to a costlier PCIe Gen 5 like Intel is to do with Alder Lake. The CPUs will retain the 105-120W TDPs as we saw with Zen 3, and it is not surprising because AMD would use a more efficient 5nm process from TSMC.

The AM5 platform will support DDR5-5200 RAMs, 28 PCIe Gen 4.0 lanes, more NVMe 4.0 & maybe support for USB 4.0. So, these Ryzen 7000 CPUs based on Zen 4 is real and coming next year; however, Intel’s progress will decide how soon AMD could bring them to the market, but not before 2022.
