Actually AMD already has a 6 core processor. It is a server processor and is not for desktops. I am sure they will release a 6 core desktop processor by the end of this year.
Yes Intel will be the first to 32 nm, but AMD release a statement back in Feb. I believe that stated they were currently targeting being the first to 28 nm. Granted, 4 nm doesn't seem like much, but we are talking about at least 4 to 8 cores based on this architecture. This provides 16 to 32 nm more space for additional core, more cache space, smaller chip size, less heat.
I just hope they can reach their goal and be the first to 28 nm. That would be the turning point if all goes well.
