Not really. Glofo had problems with their 7nm node design or something. But I didn't read the article though.

The AMD Chief Technical Officer (CTO) claimed that, though 7nm has been a big challenge it decided to go all-in, and thanks to its partners is now able to bring ahead the launch date for the technology.

Quote:
"We knew 7nm would be a big challenge, so we made the bet, we shifted our resources onto the new node," Papermaster said in an exclusive interview with CRN. "We didn't just dip our toe in the water. We went all in."
AMD had originally planned to release the first 7nm Vega GPU in 2019 but, thanks to "immense focus" has been able to move the date forward to later this year. Thus we will see the next-generation Radeon Vega Instinct GPU, demonstrated at Computex with 32GB HBM2, launched before the year is out.

We have already taped out multiple 7nm products at TSMC, including our first 7nm GPU that is planned to launch later this year, and our first 7nm server CPU that we have sampled to strategic customers and plan to launch in 2019.

I care about Zen 2 most at this point and sounds like it maybe taped out Navi also so puts them in Q1 if all goes well

Pity GF could not pull of a decent 7nm, would have given AMD good second source of 7nm chips. I think AMD would have been GF's biggest customer for 7nm and if its not to scratch for AMD... its probably pragmatic to quit digging and stick with 12/14 until they get there **** together

And then there were three: GlobalFoundries halts 7nm development

Says the same here:


https://www.anandtech.com/show/13277...nm-development




And so there are only 2 left and even then it's only the 7nm process with no idea if even smaller is possible after this point ( Samsung and TSMC )…..Global foundry owners are tired of sinking billions and not making a return on the investment for the last 10 years, and any research in 5nm or 3nm is completely halted too....



This could mean that semiconductor development that requires a new and smaller process will hit a brick wall in the next 5 years....No more competition between Nvidia, AMD, intel as they can't make them smaller at the fabs themselves....

Multi-chip-module tech may help with that. Instead trying to make giant low yield 800mm monolithic cores that run at 2GHz, you build tiny high yield modules and stitch them together with high speed interconnects.

Global Foundries has been sucking for years. Their 14nm had problems too and they had to license from Samsung. GF just isn't a first tier fab.

A lot of electronics use older nodes because they're mature and reliable and cost less, it's only stuff like GPUs/processors that really need the best process. So, maybe they can focus on producing that sort of thing. But it seems like they basically cannot hang with TSMC or Samsung anymore.

GloFo sucks. I’ve said it ever since they moved to them. They’ve been nothing but terrible, haven’t kept up with the competition, and they hurt AMD in the long run.

Problem is if TSMC becomes sole source they will up prices big time. We might find the 2000 gen Geforce prices as just a start...

Hope Samsung offers some competition there but it doesnt look likely...

Seems Nvidia isn't the only one beefing up GPU to GPU communication speeds :


https://www.guru3d.com/news-story/ra...erconnect.html


Seems AMD will be unveiling a new high speed communication bus on Vega 20, similar to what Nvidia has done with their new bus protocol, and this one is based on infinity fabric which is the same as what their thread ripper CPU's use to communicate between the active CPU dies, so it's a bus with a 50 GB/sec transfer speed between 2 active dies at least...… Both AMD's and Nvidia's are much faster than using the PCI-e bus, which tops out at 16 GB/sec for 3.0 and doubles for PCI-e 4.0 to 32 GB/sec so that put to rest the need to have a faster PCI-e bus in future motherboards......The heaviest thing one can run given the amount of data involved is a video card by far, and the rest is easy by comparison.

They'd need to make an interface 4x faster than the current X4 PCI-e used on all M2 drives to max out PCI-e 3.0 and there are cards that support 4 M2's in raid 0 but that isn't exactly cheap by any means, never mind 4.0 PCI-e being twice as fast as 3.0 so the main question is if flash memory can read and write that fast since that isn't much below the speeds of regular powered ram, as my DDR4 3200 ram using 4 channels hits a little over 80GB/sec read and writes but as you know when the power is off, all data on the sticks gets wiped out.


Making Data remain when powered off and do so at speeds 4+ times faster than today's M2 drives can read and write will take some time.
