AMD Designing Zen 4 for 2021, Zen 3 Completes Design Phase, out in 2020

[btarunr]

AMD in its 2nd generation EPYC processor launch event announced that it has completed the design phase of its next-generation "Zen 3" CPU microarchitecture, and is currently working on its successor, the "Zen 4." AMD debuted its "Zen 2" microarchitecture with the client-segment 3rd generation Ryzen desktop processor family, it made its enterprise debut with the 2nd generation EPYC. This is the first x86 CPU microarchitecture designed for the 7 nanometer silicon fabrication process, and is being built on a 7 nm DUV (deep ultraviolet) node at TSMC. It brings about double-digit percentage IPC improvements over "Zen+."

The "Zen 3" microarchitecture is designed for the next big process technology change within 7 nm, EUV (extreme ultraviolet), which allows significant increases in transistor densities, and could facilitate big improvements in energy-efficiency that could be leveraged to increase clock-speeds and performance. It could also feature new ISA instruction-sets. With "Zen 3" passing design phase, AMD will work on prototyping and testing it. The first "Zen 3" products could debut in 2020. "Zen 4" is being designed for a different era.



The "Zen 4" architecture is being designed for a 2021 market debut, and will come out at a time when the 7 nm process will have matured and attained high enough volumes at TSMC for AMD to either build bigger dies (more cores per chiplet), or leverage the even more advanced 6 nm EUV node. The maturity and volumes of these sub-10 nm nodes could change the economics of the MCM approach AMD is undertaking for its EPYC processors.

Oh wow. So no Zen 2+ or Zen 3+.

 

[my_name_is_earl]

So much hype. Still can't beat Intel in overall performance.

 

[XiGMAKiD]

Chiplet design really helps the order volume to keep delivering great product at affordable prices, I wonder how long that design choice would last

 

[TheLostSwede]

Care be specify in what? As there are a lot of things where AMD is faster and there are a lot of things where Intel is faster...
And no hype in the news post that I can see, it's just letting us know that AMD has finalised it's next gen CPU design and is working on the one after that. Intel does this all the time, no?

I would love to have what you are smoking, seems excellent stuff.

 

[Chomiq]

But they sure can beat them in price/performance ratio.

 

[ZoneDymo]

Keep the momentum going AMD, you got this!

Also, @70% in this thread, just report earl for making a baseless fanboy remark.
Dont actually quote and reply to such a silly comment.

 

[Mussels]

performance at what? highest FPS in 720p gaming?

AMD's current gen seems to be ahead in everything else

Yeah, they will need to bring down the product stack. At least make an i5 6 core/12 thread if not 8 cores. Not been up to date on the security situation, but that needs to be fixed.

I thought it was regardless of resolution? Ie ties with an i5-8400 at 4K..

I'm still curious if putting the first 8 cores on the IO would improve gaming performance (if it was all 7 nm). Some drawbacks with doing this, and some would say it's a step backwards, but i guess it could improve latencies.

No, that is EPYC 1.
EPYC 2 is much more than that, let me cite Anand who actually ran the tests:

So has AMD done the unthinkable? Beaten Intel by such a large margin that there is no contest? For now, based on our preliminary testing, that is the case. The launch of AMD's second generation EPYC processors is nothing short of historic, beating the competition by a large margin in almost every metric: performance, performance per watt and performance per dollar.

 

[GoldenX]

But muh 720p FPS.

 

[SL2]

But muh 720p FPS.

Who cares.

did you actually see the contents of the review or are you just going by avg. pefromance charts ?

web,office,encoding,doesn't seem like ryzen is ahead,or at least it isn't most of the time.if you include rendering and software development charts in a review of 3700x then sure,it's gonna get ahead of 9700k on average.

amd's glue seems to work quite fine and new generation is up to intel levels in many area , if not over them...

you may consider changing your name in near future to "my_name_was_intel"

 

[bug]

So, 2020's Zen3 is really a new architecture? Or is it Zen2+?
Or we don't know, but we write an article anyway because of page clicks?

glue works like glue,nothing new,what is new is bigger l3 victim cache.

 

[fynxer]

SPOLIER: Zen 4 will have CLX with PCIe 5.0 and DDR 5 support

 

[medi01]

Well over them, even in AVX512 scenario, where Intel still has some edge, you get this:

People are mistaking Ryzen 3000 vs Intel with higher clock, to server chips, which run at close clock.

What we know:
AMD Have said roadmap is still valid and we're executing it according to what we said in 2016.
Amd have said 2020 will be same socket.

https://www.storagereview.com/images/AMD%20datacenter%20roadmap%20EPYC.png

That means Zen3 on server platform will be DDR4 in 2020.
That is what we know for sure.

 

[Midland Dog]

Oh wow. So no Zen 2+ or Zen 3+.

i feel like zen + was a stopgap while waiting for 7nm duv to be ready anyway, zen 1 fealt like this; are we still in business? this wont sink us will it? and zen + fealt like; are we sure were good? confirm the kill

At least we get a time line for a real product. Meanwhile Intel has news about stickers...... And how they are gonna launch a GPU that can throw a football over that mountain like uncle Rico.

So... we get a timeline from AMD and a timeline from Intel, but AMD's is good?

Have you not seen Phoronix's benchmarks for Rome? In most tests, it's beating out Intel's most expensive CPU offering for a lot less money. I'm sorry, but Intel has not been keeping up with the progress AMD has been making and what you're saying is a flat out fabrication with the exception of some rare single-threaded use cases. You don't have to take it from me though. Intel, simply put, is in trouble because if I saw this as someone working in a datacenter, I would be ecstatic.
