AMD to unveil Zen 4 CPUs at CES 2022

Well at least I don't have to worry about updating system this year and can wait for it all to mature for the generation after. It still a solid update and 15% uplift is still huge compared to a decade of Intel claiming updates without showing it.

All the new IO sounds good for the longer term though and certainly seems like we wont be running out of that for gaming side at least.

Looks like a nice platform but disappointing

15% uplift vs 5950x in ST ouch Looks like IPC gains are very small and it all the ST improvement is coming from clock speed, no wonder they didn't mention IPC like they normally do.

This looks more liken Zen 3+ on 5nm with power boosted and a good foundation platform.

real Zen 4 coming next year it seems

This year's Zen 4 really does just look like Zen 3 with higher clock speeds and DDR5/PCIE5, so far upgrading from Zen 3 to 4 seems like a poor choice for value
 
That was underwhelming isn't raptor lake releasing around the same time ? Feel it will be behind that

Platform looks good for like long term will probably wait what second release of zen4 CPU is
 
I think there is a lot more to know here ye before assumptions are made. For starters it does not loiik like boost clocks are confirmed, all we got was 5Ghz+ with >15% performance gain in Cinebench. Also we had no information on what teh AI instructions will benefit or how. I certainly do not think AMD will release a brand new geneation that gets beaten by the previous Gen in games (5800X3D). My guess would be final samples do enought to beat out Alderlake in all benchmarks that matter with a refresh early next year to beat out Raptor Lake, thsi si based purely on what we have been told today not coming close to rumours of respected leakers

Be careful taking on things when people with very limited technical understanding start sharing numbers.

For example, he was quick to highlight the DDR4 latency but clearly doesn't understand the DDR4 ram he's quoting is running out of sync which is something you'd never do with DDR4 and ADL. Gear 1 is made for DDR4 on ADL. In fact, you can't even run G1 with DDR5 and vice versa, you'd never want to run G2 with DDR4.

Tuned DDR4 on adl ends up in the 40's, not 70's. https://cdn.discordapp.com/attachments/902660521889759263/929415174518091796/unknown.png (one of my rigs)

This is what makes the choice between DDR4 and DDR5 a tough one. To overtake a well tuned DDR4 ADL setup, you need to be hovering around CL32/6800 with DDR5. This not only gives you a major bandwidth advantage in games like watchdogs which is BW hungry but also lets you win in latency sensitive games.

In future generation of boards, cpu's and better IC's where you can daily something like CL32/7600+, DDR4 will be fully put to bed in all scenarios.
 
There seemed to be a lot of emphasis on I/O (not speed, but the qty) ... but for the majority of desktop users, where is that needed beyond what already exists? I wouldn't have said that the majority of users are running out of I/O, or are they ?

( Save maybe for integrated graphics and multiple displays )

This might become more important as DirectStorage becomes more commonplace.

But Zen4 not being able to beat Zen3 + 3D cache, while dissapoiting, is hardly a big surprise.

Eventually there will a Zen4 + 3D cache but only once TSMC are ready for stacking for 5nm and once demand for any server parts has been met.

Still, 5nm should have given them way more transistors so hard to see where they went so far. Probably AVX512, L2, and other things which mainly benefit servers?
 
looks like most of zen4 performance increase comes from its 180w ppt and ddr5. pulling more power to get more performance. guess they copying intel especially by using the name Mendocino which is an old celeron.
 
Honestly think I made the right choice going for a 5950x rather than waiting... all the new stuff am5/ddr5 will be higher priced than what I've just paid for mine and I'm not sure the 'performance vs cost' is there yet.

While 15% on single threaded is a nice boost but I suspect multi will be much closer overall and if the last three generations are anything to go by, it took at least a generation or two to see the true performance of the new cores, so next gen might be more interesting there..

Looks like they have a higher tdp too, which with the way electricity prices are going, and the likely higher draw from upcoming gpu's isn't exactly great imo.

Now, where did I leave those PBO instructions I haven't touched yet....

15% over a 5800X3D in games would be good but that's not what the slides show so we have to assume that's 15% over Ryen 5000 series.

Single-thread performance evaluated with Cinebench R23 1T. AMD Ryzen 9 5950X System

No gaming benchmarks shown :confused: think I will hold out for 2nd CPU on AM5

I mean the multi-thread shows 31% faster than a 12900k in test shown because the core speed is greater the multi-core has increased even greater than the single core from what they showed. It just doesn't currently look like 15% over previous as you say is worth it considering the costs of DDR5/PCIE5 etc.
 
For me this was really just the announcement for am5 and any actual cpu stuff seemed incidental. Seems like either the cpus aren't ready to be fully shown off or maybe just amd holding them back till the marketing stars align.

That said adding the igpu to the io die is fantastic news. Assuming its going to at least match the handful of rdna2 powered laptop apus is going to be a huge bonus to anyone wanting low end systems or productivity machines with some light gaming thrown in
