Tegra 2 has yield issues

Written by Fuad Abazovic

No details on what's wrong
Tegra 2 is finally happening and this is quite good news for Nvidia. Motorola, LG, Toshiba and many others plan to ship phones and tablets based on the new chip shortly.

However, a few industry sources are telling us that Nvidia is experiencing yield issues with the 40nm based Tegra 2 chip. We don’t know what is causing it but it’s appears that the issue won’t hurt Tegra 2 schedules or make an impact on its success.

LG and Motorola didn’t complained so far about the shipments but we guess that yields are not where Nvidia wants them to be and that it is simply getting more faulty chips per wafer than expected. TSMC is the factory of choice and so far Nvidia's only fab, so the issue is between the two long standing partners.

We asked Nvidia to comment and we will get back to you if we get something better than the usual no comment.

Knowing NVIDIA and there powerful tech department, I am sure they will iron out any possible issues in due time..."BUT"
40nm based Tegra 2 is really not a good idea and for that we can thank TSMC for mucking up the waters and screwing both AMD & NVIDIA out of 32nm... Good Luck NV...

lol@40nm Tegra 2 not a good idea

The article says the yield issues will not affect the schedule... but YOU say Tegra 2 on 40nm is not a good idea?

Please please please explain... with a VALID argument.

If entirely dropping 32nm wasn't enough, it appears the problems of high-k, metal gate and EUV lithography are significant for a company that hasn't used them before.

Tegra 2 is an "old" design which finally got some good designwins. I think the problem with Tegra 2 is related to that which was Fermi on the G400-series which was really crap until it meet a refresh where they remade the cores to better suit TSMC's 40nm.

Huh?

Which is the reason why they should have asked Intel for some help.
