AMD Readies 3rd Gen Ryzen "Matisse Refresh" Ryzen 7 3850X and 3750X Processors
AMD is planning to immediately update its product stack to counter the Intel 10th gen Core "Comet Lake-S" desktop processor family. Codenamed "Matisse Refresh," the processor will use existing IP, based on the 7 nm "Zen 2" microarchitecture, but could improve in areas such as clock-speeds. As it now stands, the Ryzen 9 3900X appears unfazed by the i9-10900K and i7-10700K at its new $410 price, however, competitiveness of the 3800X and 3700X could buckle under pressure from the i7-10700 series (K, KF, non-K, and F), as well as the Core i5-10600 series. To this effect, we're hearing rumors of a "Ryzen 7 3750X" and "Ryzen 7 3850X" seeing the light of the day soon, with an early-June announcement, and early-July market availability. References to the 3750X date back to October 2019.
Rumors of "Matisse Refresh" gained traction when WCCFTech editor Hassan Mujtaba tweeted a slide from a GIGABYTE AMD B550 motherboard series pre-launch presentation, which references GIGABYTE's own interpretation of AMD's roadmap. It lists out every CPU microarchitecture for the AM4 platform, and right next to "Matisse" is "& Refresh," confirming that "Matisse Refresh" is real. A microarchitecture "refresh" needn't even involve any physical changes to the processor design, core-counts, or architecture, and can sometimes even indicate something as simple as a second major wave of SKUs that replace existing SKUs in the market, leading to their phase-out (eg: Intel "Haswell Refresh" retaining the 4th gen Core model numbering). The slide also adds weight to the theory that desktop "Renoir," like its mobile counterpart, lacks PCIe gen 4.0. The slide also talks about AMD introducing the entry-level A520 desktop chipset in August, which will support PCIe gen 4 when paired with a capable processor.

If this refresh doesn't bring a substantial speed bump it's just pointless IMO :shadedshu:
A few weeks ago, a fairly reliable source sent me a "slide" he sketched up on mspaint looking at another slide. It talked about 8-core dual-CCD chips (two 4+0 CCX chiplets). The idea being reduced thermal density and double the I/O bandwidth per core to the cIOD vs current single-CCD packages; and freeing up clock-speed headroom per CCD to drive boost clocks around the 5 GHz mark. Something excruciatingly hard for Zen 2 to begin with.
I have serious doubts about this. For one, such an approach could affect performance of games that scale beyond 8 threads. It will also drive up costs for AMD, unless it's sitting on a pile of 4+0 CCDs capable of reaching 5 GHz.
Now the theory of 3850X being a 4+4 single CCD chip that's clocked to hell with increased power limits, seems more credible.
I'll put my money on single CCD 4+4.
tl;dr: go ahead and buy that 3300X, it's a solid gaming CPU (source: any 3300X review).
Unless these are the test vehicle for 7nm EUV, and the better process allowing for higher clocks.
If they announce it, that will be in september at the earliest. Wide availablity and calmed down prices probably not before november. So if the Matisse Refresh is coming right now, it makes sense.
I agree with you that these are absolutely pointless and shooting in the feet for AMD.
So, I think both will happen: 1) 4+0 CCDs in these parts 2) with higher clocks and possibly higher TDP.
Think about that last bit. Intel is pushing power limits to sky high and AMD is tying own hands at 105W. At least 3850X can possibly come out at 125W to push the gaming performance to the max while still being more power efficient than competitive Intel parts. They actually should do it.
Better bring Renoir with higher performance.
