FUD Zilla had a chat with NVIDIA's notebook general manager Rene Haas and heard the company is still planning to make external laptop graphics happen:
He didn’t mention much more than that, he merely said that Nvidia was still working on it, so stay tuned for an update. Thunderbolt connectivity was mentioned in the conversation, giving us the impression that this might the connection of a choice, but this was not confirmed by Nvidia’s mobile boss.
We got a feeling that we might see this external graphics materializing in 2012 and with 28nm Nvidia mobile chips, but this is not something we got confirmed or denied at this time.
The bottom line is, external graphics with Nvidia chips inside are happening, something that might be the future for a number of Nvidia add-in-board partners who might end up selling external graphics, as the desktop graphics market dwindles. EVGA, Gainward, Asus, MSI, XFX, TGT and other usual suspects might resort to selling notebook external cards.
