theGryphonNo way there will be odd number of cores. Makes no sense for anyone including AMD.

I expect single-CCX models as:
4 cores without SMT with 16MB cache,
4 cores with SMT with 16MB cache,
6 cores without SMT with 32MB cache,
6 cores with SMT with 32MB cache,
8 cores with SMT with 32MB cache.

Potential double-CCX models:
10 cores with SMT with 48MB cache,
12 cores with SMT with 64MB cache,
16 cores without SMT with 48MB cache (highest clocked part),
16 cores with SMT with 64MB cache.

HugsNotDrugsI think you're right but AMD will want to protect the higher margin high-performance products by creating a meaningful performance delta.

dragontamer5788AMD could easily make two IO-dies, one for DDR4 and a second for DDR5. Then use chiplet-magic to sell their processors combined with either die (saving on manufacturing costs and providing more flexibility on the supply side).

The only reason not to do this is that it'd be difficult to market correctly. Which mobos would work for DDR4, which ones for DDR5? Etc. etc. It'd be easier for consumers if all CPUs and Motherboards were under the same specs. Nonetheless, maybe an OEM-only version (for LPDRR4 laptops or some niche purpose) could be released. AMD has chiplets after all, I expect them to leverage the technology to their benefit.

InVasManiReally hard to say, but moving to DDR5 will probably entail a new socket and I imagine a new I/O die as well. Moving to 5nm on the other hand shouldn't require DDR5 so in that sense AMD has two possibilities. The chips and the chipset I feel could support DDR4 and DDR5 with different I/O die's and with different sockets. There is a minor possibility that AMD could ease the transition from DDR4 to DDR5 by allow two platforms to cater to both for Zen4 at 5nm.

In a lot of ways that a more ideal option than hybrid motherboards that support both memory types, but a good stop gap remedy for those that can't just outright afford to by new memory that tends to be expensive and not all that mature early in it's life cycle. It even opens a bit of a avenue for a upgrade later to a new socket with more mature DDR5 down the road with the same CPU and possibly a new chipset as well since DDR5's life cycle should span quite a awhile major memory architecture changes tends to progress at a slower more drawn out pace.

I think it would be more ideal to have more transitional and phased upgrades like that anyway where you don't necessarily just have that more massive upfront cost of buying everything much more periodically. Buying into increased improvements a bit a time is a easier pill to swallow to the end user. So certainly something that needs to be weighed. I think I'd be more inclined to buy into Threadripper's DDR4 EOL chip down the road rather than moving to DDR5 to be honest. At least based on my current situation. I just don't plan to replace my DDR4 memory in a real hurry quite so soon. I'm not sure what will happen with Zen4, but I guess with ThreadRipper I'm somewhat covered in either case. That said I would enjoy seeing a 5nm DDR4 Ryzen CPU personally or scaled back core count ThreadRipper DDR4 octa-channel chip with higher frequency boost would be interesting.

Rob94hawkI was curious if DDR5 was even worth it. Then I read this simple article. In a nutshell, it allows cpu's with multi cores to take advantage of the higher bandwidth.

DrediAlso, there will be literally zero chiplets coming out of the factory with just 4 working cores. It makes more sense to shift the current 4 core parts to be 6 core instead (they have as much shit broken inside anyway, and the low number of so broken chips meant that the 3300x & 3100 products could be launched only so late and with super limited stock).

CammWhether they just fuse off a second core on these to make them 6/12 is the question however.

Chrispy_So Cezanne and Zen3 will all be 5000?

I suspect they'll f*** it up again; They can't help scalp some extra hype and sales by re-releasing an existing generation with a +1000 name to make it look like new tech when Cezanne or its successor comes out.

DrediWhy wouldn’t they sell every working core that comes out of the factory, like they have done thus far?
5 or 5+5 core products make no sense, they are gimped by artificially removing 28% of the performance the chips had when they left the factory.
Do you think that AMD has such a lead now that they can afford to artificially limit the performance of new products by that much?

They might do that, just like how intel does it, by doing artificial segmentation. I hope they won’t start doing it now just as they are starting to see real progress in market share aquisition.
The real battle for market dominance is not fought with high tier products, but the 3600-class products, where they now could add a free 17% boost to core count. They can still produce meaningful deltas to higher tier products with frequency binning and how they select chips into two CCD products.

DemonicRyzen666Having both ddr4 and ddr5 adds to much complexity for the iod and is waste of silicon. it drives up the price of Iod.

DemonicRyzen666I may be entirely wrong about this
have a close look at the video posted

The Slide he shows at 10:46 shows Zen3 cores with DDR5 and PCie5..... not Zen 4

it also shows 64 x 4 for the same Zen 3 cores.... which is even more weird.

But it does makes more sense in naming the 5000 series in the end. If it already has all this inside of it for a board upgrade to move from AM4 to AM5.
