I'm glad they have cleared it up. There has been so much conjecture as to what node they would use. I didn't read though if its 7nm or 7nm+
Lebon30
I'm really glad that it's 7nm as planned! Phew!
Kaarme
Yeah, the 7nm node also has those different versions, which would cause at least small differences in the end result.
Fediuld
"7nm" has 2 processes options. N7 and N7P. The later is the process where the next console APUs are made, and probably the upcoming Ryzen XT series giving around 7-10% higher clock speeds at same power as N7.
7nm+ is the EUV process.
Lebon30
Of course I'm talking about the 7nm+ that is Zen 3. I'm glad that one is still on track for this fall as planned.

didn't really need to, anyone who wanted to know would quickly find that tmsc is only fabricating mobile chips on 5nm presently.
tunejunky
interesting, but disingenuous unless they are doing something different for custom processors (xbox, playstation) which is completely possible as they've done that before.
TSMC themselves on an earnings call specifically stated they were doing an enhanced node for AMD. whether that is "+", "++", or 5nm is unknown. custom apu's for xbox and playstation would make up enough volume for them to mention it on an earnings call, despite my and other's speculation it was rdna.
tunejunky
that is TSMC's tradition. mobile proc's first but that can change rapidly. make no mistake if yields are anything like the initial yields of 7nm, AMD will adjust their roadmap.
the road map is investor marketing anyways.
JamesSneed
Yes but they didn't say when other than give numbers for all of 2021. For sure that will include Zen4 and RDNA3 but maybe also APU's or the semi-custom stuff for HPC or consoles.

Just as well. I'd rather AMD+TSMC work on refining 7nm, to yield better overall performance and efficiency. Going to 5nm isn't going to make that big of a difference to the consumer.
Makes me all the more curious where they're getting that 15% IPC increase claim though.
Fox2232
IPC from advanced node? Magic dust. Where else?
I am sure that AMD will be close to 250~300W limit with Big Navi. So, advancement in power efficiency of next 7nm or 5nm will decide how big of an performance upgrade those chips will be.
And apparently, not wasting FLOPs is another way to deal with insufficient power efficiency improvements from more advanced manufacturing node. (But that's not as easy as it may look because intent is to flip-flop. And finding wasteful flip-flops...)
schmidtbag
Well like I said, 5nm isn't likely to make much of a difference to the consumer, meaning it won't have much of a difference on IPC. But 15% is a bold claim when they're on the same node and same socket. If it's true, that's a significant difference in the architecture.
I was actually referring more to the CPUs than GPUs. I haven't paid much attention to RDNA2 rumors since I don't care about rumors; I just want facts.

If you read all the previous roadmap, you'll understand that the 2022 point is the beginning of the year not the end. So everything appearing on that roadmap is slated to release BEFORE 2022. Plan can always change of course, but as of now AMD looks like to release at least one Zen 4 based product in 2021, could be Desktop, HEDT and/or server.
Look at a previous roadmap where it stops at Zen 3. You'll see 2021 at the end. And so far Zen 3 is scheduled to be released before 2021 begins.

Just as I predicted fake news. Just like the whole 5Ghz Ryzen rumours. 🙄
schmidtbag
What reputable source mentioned a 5GHz rumor?
Embra
Rumors are rumors, not actual news.
jwb1
It was everywhere, especially with the fanboys:
https://wccftech.com/amd-ryzen-3000-zen-2-cpu-5-ghz-overclock-4-5-ghz-all-core-boost/
https://www.digitaltrends.com/computing/amd-ryzen-3000-16-cores-rumor/
https://wccftech.com/amd-advertises-ryzen-pro-capable-of-hitting-5ghz-clock-speeds/
Do you need more?
waltc3
As expected...but it would have been interesting to see TSMC announce a mature 5nm process this year...;) Guess the financial guy misunderstood something pertinent. Typical.
Maddness
AMD is already ahead when it comes to the node they are currently using. No need to rush if the next node isn't quite there yet.
schmidtbag
Those articles aren't about Zen3, so, not sure why you're bringing up last year's rumors. I thought you were saying there are rumors of Zen3 models at 5GHz, also implying stock speeds, which we both know is ridiculous.
Even if the articles you linked to were about Zen3, the first one is talking about single-core overclocking. The digitaltrends article mentioned their non-reputable source, which literally said to take with a grain of salt. The last one, according to the comments, was a forgery (and seeing as the video was taken down, it must not have been legit) so that disqualifies it as a reputable source.
