"AMD stole the show at CES 2022 when the chipmaker gave the world a sneak peek "

what !? we must of watched different shows

hey look, stock dropped 20$ since CES 2022

Doubled cache sizes are nice, but I'm highly disappointed core counts aren't increasing if these indeed turn out to be the top end Ryzen 7 and 9 series chips. If Zen 4 based EPYC, and presumably Threadripper, chips are going to see large core count increases, one would expect AMD to have increased the core count per CCX, and therefore Ryzen chips should see more cores.

Not that most home users need more than 8 and few need more than 16 (home users defined as non-professional users), but if Intel's strategy of increased overall core counts drives more of the market to favor multi-core scaling over IPC the way their strategy of IPC over core count drove the market to per-core performance for so many years, AMD may end up on the losing end.

thats not AMD's goal.
Zen 1 brought core count.
Zen 3 brought IPC.
Zen 4 looks to bring faster clock speeds.

and honestly if you need more cores they have TR for that.
Gaming specifically has no use for more cores as only a small amount even support 8.


Do Like to see they say AM5 will last like AM4 as gives long term upgrades. (assume 2 generations)

More cores won't do a lot if software can't use it. Game makers need to focus more on that instead of trying to suck the user's wallet dry with DLC etc.

Dr Su said at CES zen4 is "in the lab".

Intel announced sampling of Alder Lake beginning in Oct 2020 (see their q3 2020 earnings call transcript). Parts shipped a yr later.

So, realistically, how far out is a shipping zen4 product?

AMD confirmed Zen4 Genoa was already sampling to hyperscalers in the last earnings call at the end of October. Zen4 desktop could probably launch at Computex in June.

Summer sale is not very lucrative for a big company like AMD. Sept, Oct is more likely launch.

 

[NightHawkRMX]

Zen2 was released in July.

 

[saltweaver]

Zen2 was released in July.

Alder Lake and Zen 3 was released in November.

 

[NightHawkRMX]

I can see either release times as likely

LGA? Ugh. I'd have to replace the motherboard if I ever bend those pins on the AM5 socket. I'd much rather replace just the CPU.

zen4 is reportedly adding avx512, which is not a small feature to support... not just the instructions, but the new throttling complexities.
Intel's SPR introduces even wilder new features ... DSA, HBM, AMX, CXL, gen3 Optane support on ddr5 memory controller.
Intel announced sampling of SPR in Nov, 2020, and it is still not shipping.
I see phoronix reports of linux driver support for new features still in evaluation for DSA, AMX on SPR.

You'd rather replace a $500 CPU over a $100-200 motherboard?????

The time and hassle of disconnecting and reattaching all those wires and peripherals from the motherboard for bent pins isn't worth it to me. And then troubleshooting problems if everything isn't reconnected properly? No thanks.
