[G3D] TSMC Unveils 6-nanometer Process

Quote:
here's always something smaller. TSMC today announced its 6-nanometer (N6) process, which provides a enhancement of its 7nm technology and offers customers a highly competitive performance-to-cost advantage as well as fast time-to-market with direct migration from N7-based designs.
...
TSMC’s N6 process delivers 18% higher logic density over the N7 process.
...
Scheduled for risk production in the first quarter of 2020
...
“TSMC N6 technology will further extend our leadership in delivering product benefits with higher performance and cost advantage beyond the current N7,” said Dr. Kevin Zhang, TSMC Vice President of Business Development.
Feels like they are going to be the top chip manufacturer very soon, considering intel are still only on their way to 10nm.

Both AMD and Nvidia could bring much stronger GPUs than 7nm could bring. And this could be great for nvidia considering they have been waiting on 7nm, so they might bring cards in 6nm instead next year, since AMD are planned to bring navi this year, so 7nm.

And if AMD could use that higher density for lower power, and if manufacturing allows, higher speeds, they could finally and completely de-throne intel from the top CPU market with 6nm CPUs and high core speeds.


Feels like this year is only going to be a preview of all the great things coming in 2020.

Neat. Anybody with the know-how care to chime in and tell us plain old enthusiasts what this means for performance?

I don't think there is going to be 6nm chips from Nvidia in 2020 as the foundry is planning to begin risk production in 2020. Finalization of the silicon may take time.

TSMC is also doing 5nm runs.

If it's ready for Zen 2+/ Zen 3 AMD will crush Intel even more.

I wonder if Intel will have to ditch its Fab, similarly to how AMD had to in the past.

Unfortunatly because risk production starts in 2020, we will most likely not see any products built on TSMC 6 nm until 2021. Still though, this is exciting! The 6 nm node will allow some load to be taken off of the 5 nm, which will mostly all go to cell phone chips.

Maybe in 2021 we will see a 6 nm refresh of 7 nm Navi?

AMD had to ditch theirs since they didn't know to manage their money. They ended up overpaying for ATi. If only they bought nVidia instead and had Jensen Huang as CEO.

This is probably for Mobile SOCs since they want all the benefits of a new node. AMD and Nvidia will just use 7nm and wait for 5nm.

Almost nothing as performance doesn't increase anymore with lower node size. It actually starts to do the opposite. You can save power but you won't automatically gain better clocks as before.

5,6,7nm... not a huge difference.

Most of these are used for low power devices.

TSMC has been on top for a long time now.

How can you say that 5, 6, and 7 nm nodes don't have a huge difference when 5 nm and 6 nm haven't even started risk production? It's far to early to be making those claims.

With that said, you are right that as nodes have been getting smaller the gains have been dropping.

Accordingly to some youtube prediction, CPU is no longer about speed but 3D stacking. In that case the IPC will be the king as high density stack will not tolerate heat that result from high frequency.


3D stacking is predicted to arrive within 2 generation from now.
