I think what we saw was a Ryzen 5 beating a i9 9900k and the Ryzen 7 will be 16 core.

Speculation of course.

At least we can expect 9900k performance on our current AMD boards in six months. My concern is pricing. Is AMD going to be agressive to gain market share ? If they edge out Intel just a little bit in gaming they may become the go to CPU for GPU benchmarks. Once that happens they don't need to price too low as the product sells its self. That could be the start of a price war , who knows.

I also think the processor we so, was a Ryzen 5, but Ryzen 7 probably will be a 12 core, I don´t see AMD releasing 16 core just yet, maybe later on the year.

Don't get me wrong, AMD could/can/will release a 2 chiplet 16 core any time they want, but I just don´t see them doing it at launch day, they'll reserve that little dessert for later.

They may release a 12 core. They could also release more than one 16 core. That is the fun in speculating. We shall see soon enough.

Was expecting to see a bit more information.
But what we did see was promising.

Which was better efficency which was expected with 7nm.
Better multi-thread performance at lower clock speed.
Clock speed boost.
A time frame to wait so now if people are thinking about upgrading to a 9900k they can make the judgement call if its worth waiting 6 months.
And most of important, no hidden chiller.


There are still some big questions left un-answered like which model they demoed, And how much further can it clock. Im hoping they are showing the chip for its efficency and there is some good head room left instead of showing a chip that pulls same power with 200 point higher score.

They will hold it back to bin chips for it.

- Early ES
- Zen 2 is supposed to have IPC increases around 10-15% (https://wccftech.com/amd-zen-2-7nm-c...ncrease-rumor/)
- Peak power consumption was only ~75W (https://www.anandtech.com/show/13829...e-4-eight-core)

If Zen+ reaches the same score at 4.35 GHz and we assume a 10-15% IPC increase based off rumors, the chip would have been at around 3.78-3.95 GHz all core turbo.

Zen+ uses ~90W at 3.8 GHz (https://forums.anandtech.com/threads...#post-39391302) and ~110W at 3.9 GHz. That would mean 17-32% lower power at the same frequency from going to 7nm.

I'm going w/ Zen2+.... My current RIG is really incredible, can handle everything i do so easy, so i can wait a year or so...

But when AMD release Zen2+ in 2020, i believe still in AM4 socket, i upgrade my R5 2600.

Good job AMD !

Interesting points over on Reddit, not being an experienced person on cinebench... i didn't know how it works with turbo boost, many mentioned that if you bench a 9900k stock it will run at 4.7Ghz all cores, so that leads me to believe that zen 2 is running 4.5-4.7Ghz, because SMT is about 10% better than HT, but the part that kinda concerns me is AMD would have brought the most binned chip they could find to the show, but one point that they keep bringing up is Lisa mentions Zen 2 competes core for core running the same with same hardware.... which is making many think this chip was running 4.7Ghz all cores to match the statement she mentioned.

Also this was leaked on AMD page.... "Łukasz Lis, The Demo Zen 2 CPU Is A Stepping B, 5D0108BBM8SH2_37(later revision, Quality Sample) Ryzen 5, 8core/16 threads, 65W TDP, at 3.7base clock , AM4 socket, hitting 4.5ghz"

Yup the various pieces of information from different sources and the numbers are starting to come together.

If you take into account pre-brief score of 2023 compared to onstage score of 2057 from Ian's Anandtech article, and add the AMD page leak data to that from @Storx post above, what we end up getting is a 3.7GHz base, 4.5GHz single core boost chip that scored 2023 in CB 15 at the pre-brief, which in turn gets PBO oc-ed a bit and that's where the 4.6GHz single core boost comes from and the 2057 CB 15 number on stage.

IPC increase seems on the lower end, could that correspond to ram running on 2666MHz ? or increased global RAM latency due to the state of ES samples and chiplet design ?

Any additional news or info on the rumors that the infinity fabric is not gonna be tied to RAM speed this time around and is gonna have an uncore clock ?

You wouldn't want a binned chip if you're showcasing a future line up as the sample provided would be better than the rest. She also stated that it was only an ES chip and that's not the final speed. ES chips are always less than or equal to the final product.
A STOCK 9900k will NOT hit 4.7ghz all core, only 4-4.1Ghz all core with some spikes at 4.7Ghz. One you remove the TDP limit you get your 4.7Ghz which is an overclock even if it's enabled from the factory by the motherborad (just like MCE).

Zen2 beat the 9900k at 4.6Ghz vs 4.7Ghz and AMD actually allowed the INTEL system to be overclocked since Intel's TDP is 95w. Allowing it to use the 120w+ to hit 4.7Ghz all core says a lot.
