Isn't this a case where Intel should not of talked about their internal R&D until they had a clear product & message to bring the market? I wonder if this lack of discipline cost Larrabee the correct narrative that it should have.
If I remember correctly, the idea at the time was to catch up to Nvidia/ATI (leapfrog them, really) in the discrete GPU market. Thus by announcing the technology long before it was ready, this would put a damper on their competitor's sales and lead. Kind of like an externalized Osborne effect.
