AMD Ryzen 3 3300X Has a fully enabled CCX, unlike the Ryzen 3 3100
This week AMD announced two entry-level quad-core processors, the Ryzen 3 3100 and 3300X. The difference between the two 4-core / 8-thread parts, however, is to be found in the way how the active processor cores are assigned.
In a block diagram leaked by ViveK oneindia.co.in (as you can see watermarked in the screenshot), you can see that there are some subtle differences in-between the two new Ryzen 3 processors. First and foremost the CCX assignments are different. While each die used for Ryzen 3000 still is a physical the 8-core (ZEN2 processor die) part, it holds two 4-core clusters with each cluster of four processors cores called a CCX.
The 3100 will get a 2+2 configuration (8MB+8MB L3) thus is grabbing two cores per CCX cluster, and that (should/could) make it slower than the 3300X for latency in relation to the full 16 MB L3 cache. The 3300X, on the other hand, has one full CCX activated, four cores e.g. 4+0, this processor will benefit from that, albeit a little. Earlier on a single thread CB15 score already leaked for the 3300X, which shows it's a potent quad-core processor. Time will tell, you can expect reviews next month.

Important question for me is, how will the 3100 compare to the 1600AF and 2600. Will Zen 2 cores be enough to sacrifice two cores and four threads for?
History has shown that, with the 3600, it is worth it vs 2700 in games. But at these lower core counts that might not be the case.

I think the 3300X will perform nearly identical to a 3600 in the majority of games. When next gen games start coming out, then the extra cores will start becoming a bigger factor.

Extra cores have been a factor for over a half decade. IMO, nobody buying a new processor for gaming should go anywhere near a 4 core, H/T or not. This is entirely processor agnostic.

^
(Almost) Completely false.
The large majority of e-sports games barely use 2 cores - basically 1 primary for logic and rendering and various low-load threads (network, sound, etc.) on the rest of the cores
4 cores are totally fine for the large majority of gamers in the world.
Also the very large majority of Indie games are (still) single-threaded.
BUT...
If you're talking strictly about AAA titles on the newest engines, then yes, 6 cores or more are better.

Thanks Hilbert. That was a quick answer to a question I had. I bought a 2400G because I wanted a Ryzen with a single CCX and hoped it would be some of the best silicon offered from Zen.
I didn't really expect to see a configuration like the 3100. I thought the yields were good enough that we wouldn't see such a salvage operation with Zen2, but AMD might as well use all the silicon they can.
