AMD to unveil Zen 4 CPUs at CES 2022

[EsaT]

DDR5 engineering samples have been a thing for over 2 years now, how you think all this new hardware gets tested pre release?

And how do we know that your rather fresh suspiciously high post count per day account isn't from Putin's... err Intel's troll factory with the way you preach that AMD can't ever do better than Intel?

4½ years old DDR5 draft had kind of placeholder even for 8400MHz, so very high speeds have been in mind since the early days of DDR5.

And SK Hynix was testing 5200MHz DDR5 chips over three years ago.

So AMD has had plenty of time to develop and test new DDR5 memory controller and IO die.
With Zen3 using basically same IO die as Zen2 that released engineers to do other things like develop DDR5 platform.

I do think think it will be better than ADLs memory controller which needs 2-1 but I'd suspect 1-1 will top out around 2400mhz which should still be quite good for a first attempt but then this is all speculation at this point so feel free to give us your take if you think AMD will do better than that.

It doesn't matter if it is first attempt, actually ryzen mobile 6000 series are first attempt. They have access bleeding edge node, and time. Zen 4 will release probably around september-november, and there will be more and better ddr5 modules by taht time, so enough time to improve memory controller. And they won't allow to fall behind Raptor Lake. Zen 4 biggest advantage over Raptor Lake is ddr5 only controller, as i said many times, hybrid design have too many compromises.

6900HX benchmarks pop up, but the Intel alder lake 12900H still easily beats it by 40%.

Right now, Intel has a big advantage in the number of CPU cores it can put into a laptop compared to AMD

number of CPU cores it can put into a laptop

who cares about that? past 4 cores it doesn't matter.
Intel does have a slight single core advantage. And AMD has faster graphics (I presume)
It remains to be seen which is more power efficient

So why isn't AMD and Intel making high end 4 core CPUs. Because people buy the models that have more cores - so clearly people do care otherwise they wouldn't manufacture it

I expect when AMD announces its own 12 core laptop you will also say "who cares"

something I dont get about the Zen4 rumours, the latest one claims that AMD has improved all core clocks by 10%. And yet Lisa showed a CPU running all core 5ghz, thats like 50% more, not 10%

wasn't it in game? So 5GHz not all-core boost?

Also, +10% to current all core boost of 5800X (4.6) could be over 5GHz.

 

[LePhuronn]

Pretty sure they made the point that during the game all cores were running at 5GHz.

No it isn't. I can get allcore 4.6Ghz fine on my 5950x and it not even a great chip. So 10% puts that allcore to 5.06Ghz then. So it is exactly what it said it is and your maths seems a little off since you are suggesting that allcore on 5000 series is only 2.5Ghz which is rubbhs.

I meant not all-core-full-load-cinebench-boost, sorry.

 

[Curlyriff]

I meant not all-core-full-load-cinebench-boost, sorry.

Shall see. If the 10% is there and is all-core full load boost it would be right on claim from what we currently have which is about 4.6Ghz allcore full load boost just fine.

Not out of the box mate. The 5950x stock runs at like 3.6ghz, so 5ghz all core STOCK is 40% increase

I don't think Lisa would have been using overclocked Zen 4, because then its a low score Zen 3 can already be overclocked to 6ghz with the right cooling. AMD would be demoing CPU's running stock

At stock my 5950x allcore is 4.2Ghz so would be 20%. A friends 5800x allcore stock is 4.6Ghz though so it all depends on the chip. And what rubbish you talking about can run at 6Ghz all core with right cooling. Get out of here.

Edit: Don't suggest LN2. We talking about consumer cooling in a PC be it AIO, Watercool loop. Not some chiller or LN2 setup.

No it doesn't, 5950X range from 4.0Ghz to 4.4Ghz all core in Cinebench. In games individual or multiple cores clock to about 5Ghz. it depends how many amps the CPU is pulling and / or temps.

 

[five8five]

Does AMD publish all-core boosts?

 

[humbug]

Does AMD publish all-core boosts?

No, its not a fixed thing, to use the 5950X as an example the all core boost is anything from 4.0Ghz to 5.0Ghz (sometimes even higher) and everything in 25Mhz increments between, depending on the quality of the silicon, your cooling, your motherboard and what the CPU is doing.

AMD don't publish fixed boost clocks because there are none, they are not fixed clock CPU's.

 

[humbug]

To expand on it it gets even weirder.

My CPU is advertised as having a base clock of 3.8Ghz. That base clock is the minimum AMD guarantee the CPU to run at with a 105 Watt TDP cooler, that would be AMD's own Wraith Spire Cooler (That's the taller round one) even with it it would boost a bit higher, unless its a really bad bin. Before tuning the package power on my 5800X is about 120 Watts at 4.65Ghz in Cinebench MT. After tuning its 107 watts at 4.8Ghz

The advertised boost clock is up to 4.7Ghz, it only needs to do that on one thread, even with the Wraith Spire Cooler it will do that easily, it can do it on all 16 at the same time, mine out of the box boosts to 4.85Ghz on all 16 in games and stops there, that's its hard limit at stock, they do this to segment the CPU's, the 5900X has a stock hard limit of 5.0Ghz, the 5950X 5.15Ghz. i have tuned mine with +150Mhz on top of the boost and it sticks to 5.0Ghz on all 16 in pretty much any game.

The Zen 3 CPU monitors its self and the motherboard its sitting on is all conceivable ways, Amps, Voltage, Temperatures.... but not just as an over all package like an Nvidia GPU edge temp, there are more than 60 sensors all over the CPU monitoring those aspects, it uses that data to optimise its self on the fly every one millisecond, or 1000 time every second.

We used to get excited about technologies like this, 20 years ago Anand would have had a huge technical write up about it, now no one cares and i think its a shame, because this is some Voodoo #### right here.

How do you get 4.2ghz? When I run CBR23 its 3.6-3.7ghz and pulling 120-130w. Only when I enable PBO does it go up to 4.45ghz

 

[Grim5]

No it doesn't, 5950X range from 4.0Ghz to 4.4Ghz all core in Cinebench. In games individual or multiple cores clock to about 5Ghz. it depends how many amps the CPU is pulling and / or temps.

mine only runs at 3.6-3.7ghz in cinebench r23, what gives? Score is 24k
