DigiTimes had a chat with NVIDIA general manager of MCP business Drew Henry. When speaking about Fermi, Henry said rumors about yields being lower than 20 percent are completely untrue. He claims they currently have everything under control, and says they have a chance to launch a 512-core Fermi in the future.
Q: What are your comments on the rumors that Nvidia has blocked some graphics cores with problems on their GeForce 480/470 chips causing these chips to have less than 512 cores due to Taiwan Semiconductor Manufacturing Company's (TSMC's) low yields?
A: Nvidia does not comment on unannounced products; however, we have a chance to launch a graphics chip with 512 cores in the future.
TSMC's yields for its 40nm process has met our expectations and market rumors about the yields being lower than 20% are completely untrue. We currently have everything under control.
