15th September, 2022, is when AMD will debut its Ryzen 7000 "Zen 4" desktop processors. The launch strategy of these chips looks similar to that of the Ryzen 5000 series. The company is preparing a lean launch lineup with just four SKUs—the Ryzen 9 7950X, the Ryzen 9 7900X, Ryzen 7 7800X, and the Ryzen 5 7600X. These SKUs succeed the 5950X, 5900X, 5800X, and 5600X, which made up the previous launch lineup. AMD in its recent interview with us, made it clear that 16-core/32-thread is the maximum core-count for the 7000 series, which would make the 7950X such a chip. The core-counts of the other SKUs are not known. All these models are built in the Socket AM5 package, featuring PCI-Express Gen 5 and DDR5 interfaces. But wait, there's more.

Although AMD led us to believe that it's going all-in with DDR5, we're hearing a spectacular rumor that suggests otherwise. Apparently, the company is designing Socket AM4 processors with "Zen 4" chiplets, possibly paired with the existing cIOD that supports PCI-Express Gen 4 and DDR4 interfaces. The rumor surfaced among sources lower down the supply-chain (resellers). It seems like AMD isn't convinced it could target the lower-end of the market with AM5 just yet, and isn't 100% confident that affordable DDR5 memory will come through in time. The "Zen 4" + AM4 processors would compete with Intel 600-series chipset motherboards that have DDR4 and PCIe Gen 4 connectivity. Trouble is, you can upgrade your Intel LGA1700 motherboard to one that has DDR5+PCIe Gen5 while keeping your processor; but you can't do so with an AM4 Zen 4 processor (you're stuck on AM4). AMD still gets to sell some processors, and those with AM4 platforms can rejoice.

It looks like the advantages of the chiplet design are finally starting to show on the user level as well. They just have to get the IHS right to make sure such CPUs don't run like a furnace.

The wording on this is kinda weird, cause even if the rumor becomes true, AM5 will still be DDR5 exclusive.
 
ZEN4 on AM4!

There is no trouble at all. Sell your old AM4 setup and upgrade to new AM5 DDR5 platform when prices are lower.

You would probably have to sell your old Intel 1700 DDR4 board + RAM to upgrade to 1700 DDR5 platform.

I dont see this being a con for AM4 users just pop the ZEN4 CPU into an already existing setup and sell your current CPU to cover some of the cost.

Tbh even in my country here DDR5 prices are dropping, even 8 or 16 GB DDR5 Sodimms for the latest gen laptops are dropping real fast. September is still 3 months away, plenty of time to drop even further.

Fixed, thanks.
 
I've said it from the beginning that going all-in DDR5 is too radical and has a high chance of backfiring.

But kudos to AMD for not choosing the keep lower end users on Zen3 instead.
 
im excited to see the ryzen 5 7600x, keen to see how much perf bump from 5600x, exciting times
 
Hmm, this news indicates that AMD is sitting on a too large stock of Zen 4 chiplets with less than 6 usable cores, so their CTRO came up with this idea. Will we see Zen 2, Zen 3 AND Zen 4 launches in 2022, all three of them on the AM4 socket?

*Chief Technology Recycling Officer, I'm sure AMD has one

Not at all. It simply indicates AMD realized anything that's not high-end doesn't need DDR5 and decided to pair the chiplet with a DDR4 IO die.

For the record, there will be bad dies and more of them at first. But simply announcing there will be DDR4 enabled Zen4 is not an indicator of the yields.

I doubt that. TSMC's 5nm is a very mature node at this point. Not as high yielding as 7nm but problably still very good.
I think if AMD goes this route they wont bring high performance chiplets to AM4 like those on 7950X. Im guessing these AM4 parts could be something like R5 7500/7600 level at best. Also it's very likely that if that's the case then 5800X3D will remain the fastest AM4 gaming focused CPU having both core and cache advantage over these Zen4 chiplets.
 
Possible AM5 CPU on AM4? wow just wow, what a socket!
 
“Trouble is, you can upgrade your Intel LGA1700 motherboard to one that has DDR5+PCIe Gen5 while keeping your processor…”

How do you upgrade a motherboard? Do you mean replace?

Nvm. Upgrade can mean replace for something better. Need more coffee.

Possible Zen4 CPU on AM4. There's nothing inherently "AM5" about Zen4, afaik.

Using the vulgar fraction notation, it would be AM⅘.

Yeah, I just said "indication", there would have to be many more of them to make a solid proof. AMD also uses chiplets with 4 or less good cores for Epyc CPUs.

AMD would also need to develop a new I/O die, one with integrated graphics, for those low end Zen4/AM4 CPUs. Businesses that buy i3/Ryzen 3 class PCs in volume would rather not pay more for discrete GPUs.

The IGP is not I/O, so it's not on the I/O die. The current I/O die used for Zen3 would suffice.
But we don't know AMD wants to go that low with Zen4.
 
I could do 7950x on am4 that would be fun to play with a new cpu :D - super combo with a 7950XT graphics card

Here's a mockup of what was shown regarding TSMC's N4 D0 defect rate compared to previous nodes. Grey line shows high volume manufacturing start (N4 beyond HVM is estimated)

Well, that's put a spanner in the works, hasn't it? Here we all are waiting for AM5 and Zen 4 and now they've just confused the shit out of us! I had an upgrade path to follow and now that's fecked! Thanks AMD.
