Nvidia’s 512-core GT300 Taped Out At 40nm, Already In A1 Silicon


Nvidia’s next-gen Tesla GPGPU engine, the 40nm GT300 GPU, has been confirmed to be in A1 silicon at Nvidia’s labs, meaning it actually taped out sometime in January, February or March.

The first silicon produced would’ve been A0, meaning Nvidia is already through one stepping pre-production, which is not uncommon. In fact there may be a solid explanation for it as it was previously rumored that both ATI and Nvidia are having trouble with TSMC’s 40nm process technology, and that could be affecting yields. If true, then the re-spin (moving from one stepping to another) could be done not for performance reasons exactly, but rather to address TSMC’s 40nm issues.
