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.

It won't hurt your other SKUs and probably sell well considering the price RTX 4090/ 4080s are selling for.
E-peen FTW!
I wonder if they are playing with the scheduler to make one CCD the "P" cores to the OS.
With a low failure rate, they'd never finanically bother
Because these 3D chiplets need lower voltages, they cant run at the same clockspeeds and wattages as the regular chips - they'd get slaughtered by the basic websites that only care about the clock speed and the cinebench scores
going beyond a single CCX is a big risk because it hurts what these chips are best at - low latency cached data
The trouble is, it would seem drastically expensive for a mere 6-core Ryzen 5. Probably over the price of the 7700X at minimum.
Look at the image posted just there ^
Some really useful reviews are those that show the impact of X3D by category:
1. Entry-middle video card for 1080p (6500-6600XT/3050-3060)
2. Mainstream-high video card for 1440p (6700-6800XT/3070-3080)
Above, at the enthusiast, we have, but most of them use video cards from the categories listed above.
As I said before, I prefer to direct the X-X3D price difference towards the video card. I say you get better at fps.
AMD is in desperate need of a gaming king processor. Paradoxically, if it succeeds, the buyer will lose because the prices will be high.
I get 16 P cores clocked over 5000 MHz, 192 MB cache with DDR5 RAM. It's the creme de la creme.
Throw in the LG 45 inch 240 Hz OLED Monitor that was recently released and you have the best personal computing setup on the planet.
I just hope that in time there will be use to those high capacity catch CPU besides only some of the games, that is common applications as well.
I picked my 7700X for $330 so they could make the $400 7700X3D and so on.
Performance between 7900X and 13700K is close one is better at gaming the other better at compute.
Looking at compute. 5800X3D does fall to the bottom of the chart. Despite being at the bottom of the chart less than 5% slower than a 12600K at compute.
Local (India) market the 7700X and 5800X3D are priced about the same.
There is also a price performance chart but that has old prices so never post it.
