TSMC's 5nm yields reportedly cross 7nm, AMD hinted as a customer for Zen 4's launch

5nm is set to be another successful node for TSMC.



Read more about TSMC's high initial 5nm yields.

I'd expect AMD to use 5nm for Zen 4 as it would tally with when they could move on from AM4 onto AM5, DDR5, and whatnot. Logically speaking

Soo many fives... I wonder if they will launch on 5/5/21.

I also expect AMD to move to 5nm in 2021, as AMD needs to remain on the best process possible to continue to make gains over Intel. If 5nm is ready, AMD will use 5nm.

I just don't like the sites that are talking about the speculations of a Chinese site like it is confirmation. So many rumours are spoken about in this way and I'm kinda sick of it. I always do my best to cite rumours as such.

You do a good job of it too and keep us up to date on all the latest that are going around that have any kind of credibility or have a lot of attention.
Keep it up, this site is always my first choice on tech news and is very reliable

But would there be a somewhat "big" difference going 5nm from 3rd gen Ryzen's 7nm?...

Add PCIe 5.0 onto those fives
Yea, it especially bugs me when people use machine translation like Google then pass it off as fact even though everyone knows those translation systems aren't 100% accurate.

I don't think it'll be a big difference but they need to keep on the cutting edge to challenge Intel. I think they'll jump just to make it a completely new platform for AM5.

Well, this will be Zen 4 at that stage and the increased silicon density of 5nm will allow AMD to make some BIG changes. More cores, or better yet, bigger cores with more features to boost IPC.

Yes, but complacency is what has killed Intel's dominant market position. AMD shouldn't make the same mistake.

Beyond that, the increased silicon density of 5nm should allow AMD to bring forward some huge design changes. Yeah, it won't be the same as 14/12nm to 7nm, but it will make a notable difference.

Yeah, anything that comes from a machine translation should be taken with a grain of salt. I remember speaking to a Japanese guy on Twitter once to try and settle a translation issue. @KOMACHI_ENSAKA, good guy.

That said, some sites almost always misrepresent rumours for the sake of a headline.

From TSMC about the ARM Cortex A72: "TSMC stated that they could increase logic density by 1.8x and boost is operation speeds by 15% or reduce its power consumption by 30%." We can infer a few things from this to apply to Zen2/3 on 5nm. Given the limitations of Zen 2 with it's achievable clock speeds, we may see a 5% increase in maximum single core clock speeds or a more consistent but lower base/multicore boost and we will probably see either lower power consumption or more features packed into the chip.

In other words, we will see yet more improvements in the Zen architecture which will help AMD stay competitive with Intel even if Intel pulls something from their rear on their 10/7 nm processes.

Yeah yeah, I get that there obviously will be an improvement. Otherwise it would be a bit pointless and not much logic behind a new generation of processors.

What I meant more is if it would likely be an benefit of going next gen over 3rd gen Ryzen?...

I just wish that AMD takes their time with 5nm and Zen 4. Their CPUs are good but they seem half-baked. I understand that they had a gap when Intel was sleeping and they needed to move product fast. Their technology has so much potential. It needs refinement.

I have a feeling that Lisa Su comes in the lab and says "Is it ready? We need to send the designs to TSMC today so they can start making them."

The engineer "Sample v0.732 failed. Final version won't be for another 6 months."

Lisa "If sample v0.6 was good send them that one."

Edit: And then the Micro Code team gets hart attack because all code optimizations for v0.6 weren't supposed to be in final version.
