Updated: AMD Ryzen 7000X3D launches February 14th 2023
There will be a new packaging style for the three incoming Ryzen 7000X3D processors. The logo for the new '3D Vertical Cache technology' will be prominently displayed in orange and silver on the PIB (Processor in Box) packaging.
AMD also announced that the base TDP for Ryzen 7000X3D processors would be reduced by 50W to 120W. Furthermore, the new series' Tjmax (operating temperature) is lower at 89 degrees Celsius, down from 95 degrees Celsius (on the X-series). That's 1°C different than the previous-generation Ryzen 7 5800X3D processor.AMD will not allow full overclocking capability on the new products. Manual overclocking will still be impossible, despite the fact that 7000X3D components will have a greater maximum voltage (1.4V vs. 1.1V) than the previous generation. While additional information on AMD's 7000X3D processors will be released before their February release, the company is still hesitant to provide many specifics.
Update: AMD posted on it's website the release date for the new X3d processor, that's the 14th of February 2023
It's worth noting that the 7000X3D series will feature support for PBO (Precision Boost Overdrive) and Curve Optimizer, indicating that AMD permits some granularity in fine-tuning for the new series with 3D V-Cache. In order to optimize these power- and voltage-conscious CPUs, this is the suggested and risk-free choice.AMD has launched three Ryzen 7000X3D models with 3D V-Cache, increasing the number of X3D CPUs for client PCs from one (in the case of the Ryzen 5000 family) to three (for the Ryzen 7000 series).
| AMD Ryzen 7000 Zen4 | Architecture | Cores/Threads | Base /Turbo | L2 + L3 | TDP | iGPU | Price |
|---|---|---|---|---|---|---|---|
| Ryzen 9 7950X3D | Zen 4 | 16/32 | 4.2/5.7 GHz | 16+64+64 MB | 120 W | yes | |
| Ryzen 9 7950X | Zen 4 | 16/32 | 4.5/5.7 GHz | 16+64 MB | 170 W | yes | 849 Euro (699 USD) |
| Ryzen 9 7900X3D | Zen 4 | 12/24 | 4.4/5.6 GHz | 12+64+64 MB | 120 W | yes | |
| Ryzen 9 7900X | Zen 4 | 12/24 | 4.7/5.6 GHz | 12+64 MB | 170 W | yes | 669 Euro (549 USD) |
| Ryzen 7 7800X3D | Zen 4 | 8/16 | 4.x/5.0 GHz | 8+32+64 MB | 120 W | yes | |
| Ryzen 7 5800X3D | Zen 3 | 8/16 | 3.4/4.5 GHz | 4+32+64 MB | 105 W | yes | 489 Euro (449 USD) |
| Ryzen 7 7700X | Zen 4 | 8/16 | 4.5/5.4 GHz | 8+32 MB | 105 W | yes | 479 Euro (399 USD) |
| Ryzen 5 7600X | Zen 4 | 6/12 | 4.7/5.3 GHz | 6+32 MB | 105 W | yes | 359 Euro (299 USD) |
All three processors get a 120W-rated TDP bringing back these processors towards better manageable temperatures. All factors combined can make these processors the most desirable of the year for the gaming end-consumer. The caches are interesting, the Dual-CCD 7900X3D and 7950X3D were demonstrated, with respective total caches of 140 MB and 144 MB. And that means one CCD has a 32 MB L3 cache on-die, and the other is a standard planar CCD.
Also new is the fact that "X3D" does not always imply lower turbo clock rates. At the very least, the two larger models no longer lose the maximum turbo clock when compared to their X siblings: AMD continues to specify the Ryzen 9 7950X at up to 5.7 GHz and the Ryzen 9 7900X3D at up to 5.6 GHz. The Ryzen 7 7800X3D has a maximum clock speed of 5.0 GHz, while the Ryzen 7 7700X has a maximum clock speed of 5.4 GHz. The Ryzen 9's high turbo is because the cache chip is carried by only one chiplet. AMD has also established a TDP of 120 watts for all three X3D CPUs. This is more than the Ryzen 7 7700X's 105 watts, but less than the two existing Ryzen 9s' 170 watts out of the box. The step makes sense in light of the X3D CPUs' intended application.
AMD released its Zen 4-based Ryzen 7000-series desktop processors in September 2022. They have excellent single-threaded performance (thanks partly to their ultra-high clock speeds), which means they can compete well against Intel's 12th and 13th-generation parts. AMD claims its Ryzen 7000X3D processors are 13–24% faster than Intel's Core i9-13900K in early benchmarks. The Ryzen 7800X3D, on the other hand, is 21-30% faster than the Ryzen 7 5800X3D across four AMD-tested games. The company also claims that the new processors outperform the previous Ryzen 7 5800X3D in creative workloads. The launch of the processors is scheduled for February. To date, AMD has not provided a recommended retail price.

I'm extremely skeptical about this hybrid design. These dual CCD CPUs have one problem already, which is increased inter-chip latency between different CCDs and scheduler has to take this into account. And now we are adding another level of decisions on top of that, depending on some arbitrary cache vs frequency decisions, which imho will never work 100%. Scheduler will never be able to predict whether some process will benefit from more cache at some point. Even like 1kb executable can benefit from 50MBs of cache and vice versa. It's similar to Intel's e-cores. There will always be situations, where the system will run suboptimal.

Because of this I am looking more to the 7800X3D rather than the above models, which in theory could run better assuming there isn't latency spides, do wonder if the cache on one side is going to make this worse.
Though going form a 8700k to 7800X3D I am guessing will be such a huge jump looking at a few more % increase in a few cases just won't matter
Glad power looks to be more managed this time around as well as the 7000 series seemed a little power hungry (eco mode seems to be a game changer i've heard)

Is this cost saving on the 79xx3d ? On one hand you get a ton of more cache and a lower clock speed on one cc'd and on the other you can boost buisness as usual .... So in theory single core oriented applications that just need speed will not loose from the lower clocks and giving more weight on the non 3d ccd and when an application benefits from the increased cache will be using the 3d ccd , in theory that can be best of both worlds witha huge .... Enormous if ! IF the windows scheduler does good scheduling nwitch is a big if.
If I would have to take a guess is that this is cost saving measure first .... And trying to make the best out of it later.

There's only one thing i don't understand and thats the 7800X3D is a single ccx compared to the 7900 and 7950 with 2 ccx's so how can they all be 120w.
This makes no sense to me. I would of thought the 7800X3D would be a 95w or less because of the 1 ccx.

But, will the overall upgrade cost be worth the jump in performance.
For those already running a 7 series probably but maybe not for those on AM4 (5800X3D)
