AMD Confirms "Zen 3" with 64 MB 3DV Cache for Q1-2022, "Zen 4" Later, PCIe Gen5 + DDR5
AMD today celebrated 5 Years of Ryzen, with a special video presentation by John Taylor, AMD Chief Marketing Officer, and Robert Hallock, Director of Technical Marketing. The company confirmed that its next Ryzen processors will come out only in Q1-2022. These processors will feature updated CPU core complex dies (CCDs) that combine the existing "Zen 3" microarchitecture with 64 MB of additional 3D Vertical Cache memory. AMD claims that this change improves performance by anywhere between 4% to 25% for games, amounting to the kind of performance uplifts you'd expect from a new processor generation.
AMD did not reveal whether the updated processors will be branded within the existing Ryzen 5000 series, or newer Ryzen 6000 series. If you remember, the "Zen+" microarchitecture enabled AMD to come up with a whole new generation, the Ryzen 2000 series, despite modest 4% IPC uplifts, albeit significant improvements to the boosting behavior, resulting in improved multi-threaded performance. What remains unclear is whether the updated "Zen 3" chips with 3DV Cache will herald a new platform, or whether these chips will be built on the existing Socket AM4 with DDR4 memory and PCI-Express Gen 4.AMD's next truly next-generation Ryzen processor will come out within 2022, the company confirmed. Based on the new "Zen 4" microarchitecture, the company is targeting significant IPC uplifts, that will help it compete with Intel; but more importantly, introduce the new Socket AM5. An LGA package with 1,718 pins, AM5 will enable next-gen I/O. The "Zen 4" based next-gen Ryzen will indeed feature the combination of DDR5 memory and PCI-Express Gen 5, letting AMD level up to Intel on that front.
AMD's 2022 roadmap for desktop Ryzen processors looks quite similar to its 2020 roadmap. The company had initially refreshed its Ryzen 3000 series with a trio of Ryzen 3000XT SKUs that missed the mark of being viable stopgaps; but followed it up with the groundbreaking Ryzen 5000 "Zen 3" series toward the end of the year. 2021 will go down as an year without any new Ryzen processor generation.
Another aspect of Socket AM5 confirmed by AMD in the presentation was backwards compatibility of coolers with Socket AM4. You'll be able to retain your AM4-compatible coolers for AM5, without needing any adapters or upgrades to your coolers' retention modules.
As for a concrete response to Intel's Hybrid CPU core designs that the company will be pioneering on the desktop PC with "Alder Lake," AMD doesn't appear to be having a hybrid core design of its own, but hinted at the possibility that it is working on a new power-management solution built from the ground up, which will probably run a homogeneous set of CPU cores across very different performance/Watt bands, while retaining a consistent ISA. AMD has given this a rather uninteresting name—Power Management Framework.

It was supposed that these can be on AM4 because it is the refresh but at all, no one knows it.
Zen3 CPUs are an excellent choice for these two MOBA games, in which the fps do matter.
To use standard cooling methods and keep the die flat, all of the area which sits next to the raised layer of cache needs to be filled with something..ie..silicon. Silicon is not an ideal conductor of heat; transfers heat at a slower rate when compared to other materials. Additionally, the lower of the two cache arrangements will most certainly run warmer than the stack closest to the heatsink.
Negligible or not, stacking is not ideal. It's a move to curb ADL gains. I surmise the next iteration of Zen will begin to move away from disparate chiplets back to a more monolithic design.
Regarding the second point.. Im pretty sure we're saying the same thing (again). Substrate Infinity fabric limitation is the long pole in the tent with the current design. DDR5 should facilitate faster fabric speeds but memory controller efficiency and fabric design come into play. Especially if denser core count chiplets are the go-forward plan. I'm interested to see what happens with TR. The lower core count Ryzen designs shouldn't be a huge issue.

My 3600XT was great, hope its new owner feels the same.
I just want that 2000 FCLK 1:1, and the cache :)
* issues with differences in thermal expansion between Cu and Si (you don't want to create a bimetallic strip)
* methods of bonding Si to Si may be less costly or less problematic than methods of bonding Si to Cu.
Are we doing the periodic table of elements now? Sweet!
Si is a go-to choice for processing dies because it doesn't "thermally expand". It retains its atomic structure when heat stressed (to a logical processor construction/operation threshold).
Si based dies are full of Cu traces! Why do yall insist on this bs spin gibberish..?
Games will be optimised better for rDNA 2 and Ryzen - Xbox series x and ps5 has a the cpu and GPU. Never underestimate AMD.
It would be very hard for them to do fab orders. They have a limited supply from TSMC and if the product is super good then it probly won't be enough and throw in chip shortages, then its probly well short of the amount needed.
If the product is not so good then you have probly over ordered and will be stuck with excess and trying to flog it off to recoup some of your loss. They are not any where near as big especially financially as Intel who could absorb it much better . Plus they make their own chips.
If AMD weren't so successful with Epyc and Thread Ripper then Intel would still be shoving 4core cpus down our throats and make you pay through the nose!
It has reinvigorated a very stagnant industry!
With the whole TPM and security obsession more programs could be locked out of support even if they don't necessairly need Win11 it self as an OS platform, it's really all subjective in programming what the program is designed to support and it's usually someone's decision to not support something, singleplayer games or those with SP modes shouldn't outright warrant all of this, only should enforce the requirement when multiplayer and anti-cheat's are launched.
Without release Renoir or the 5300G on the retail market, il piss on AMD too.
Shithole Company :laugh:
