AMD Readies 16-core, 12-core, and 8-core Ryzen 7000X3D "Zen 4" Processors
AMD is firing full cylinders to release a new line of Ryzen 7000-series "Zen 4" Socket AM5 desktop processors featuring 3D Vertical Cache, at the earliest. Faced with a significant drop in demand due to the slump in the PC industry, and renewed competition from Intel in the form of its 13th Gen Core "Raptor Lake" processors, the company is looking to launch the Ryzen 7000X3D desktop processors within January 2023, with product unveiling expected at AMD's 2023 International CES event. The 3D Vertical Cache technology had a profound impact on the gaming performance of the older "Zen 3" architecture, bringing it up to levels competitive with those of the 12th Gen Core "Alder Lake" processors, and while gaming performance of the Ryzen 7000 "Zen 4" processors launched till take match or beat "Alder Lake," they fall behind those of the 13th Gen "Raptor Lake," which is exactly what AMD hopes to remedy with the Ryzen 7000X3D series.
In a report, Korean tech publication Quasar Zone states that AMD is planning to release 16-core/32-thread, 12-core/24-thread, and 8-core/16-thread SKUs in the Ryzen 7000X3D series. These would use one or two "Zen 4" chiplets with stacked 3D Vertical Cache memory. A large amount of cache memory operating at the same speed as the on-die L3 cache, is made contiguous with it and stacked on top of the region of the CCD (chiplet) that has the L3 cache, while the region with the CPU cores has structural silicon that conveys heat to the surface. On "Zen 3," the 32 MB on-die cache is appended with 64 MB of stacked cache memory operating at the same speed, giving the processor 96 MB of L3 cache that's uniformly accessible by all CPU cores on the CCD. This large cache memory positively impacts gaming performance on the Ryzen 7 5800X3D in comparison to the 5800X; and a similar uplift is expected for the 7000X3D series over their regular 7000-series counterparts.
The naming of these 7000X3D series SKUs is uncertain. It's possible that the 16-core part is called the 7950X3D, and the 12-core part 7900X3D; but the 8-core part may either be called the 7700X3D or 7800X3D. Quasar Zone also posted some theoretical performance projections for the 7950X3D based on the kind of performance uplifts 3DV cache yielded for "Zen 3" in the 5800X3D. According to these, the theoretical 7950X3D would easily match or beat the gaming performance of the Core i9-13900K, which begins to explain why Intel is scampering to launch the faster Core i9-13900KS with a boost frequency of 6.00 GHz or higher. The report also confirms that there won't be a 6-core/12-thread 7600X3D as previously thought.

I could also easily see AMD pulling in Threadripper 6000 (Zen 4 based) as they don't need to worry about not having enough chiplets for Epyc like they did during Zen 3, things aren't flying off the shelves right now (hence the massive price cuts to Ryzen) so they have more than enough production for all variants for all markets.
I also don't believe AMD can afford to take their foot off the gas right now, they need all the performance crowns they can get to help fight Nvidia mindshare for their Radeon division. So if Zen 4 3D wins in gaming, Zen 4 Epyc wins in servers and Zen 4 Threadripper wins in workstation then the 7900XTX will subconsciously get a much better reception because 'AMD' is seen as a dominant winner.
Personally I expect a less impact on clockspeeds this generation. But I will be surprised if there are none.
Yes, it is a little less snappy in day-to-day stuff compared to my 5900X boosting to 5150, but it is still livable. It is pretty sucky that they locked it down so much, but I can see why... there are many people who complain about its temps, not sure what to say about that tbh. AIOs suck? :laugh:

I wouldn't say that the 5800X3D sucks at productivity. I've had a 4770K for yeaaaaaars before I jump to AM4 and most of us were stuck in the 4/8 era. And now a 8/16 cpu is garbage?
And practically until now, only a few cpus (3950X, 5900X, 5950X and the 12th gen Intels) have been faster than this by a meaningful margin.
To be fair that might include some CPU’s from Intel too...
