So far Intel's roadmaps for 2008 indicate the fastest quad-core processor will be the 3.2GHz QX9770. FUD Zilla reports it's not easy to keep the TDP under 130W at these clockspeeds as the QX9770 already exceeds this level with a TDP of 136W.
According to the current Intel roadmap it doesn’t look that Intel plans to release anything faster than 3.2GHz for the remainder of the year. The next CPU after QX9770 is Bloomfield, a version of a Nehalem marchitecture with quad core and eight threads scheduled for Q4 2008 introduction.
This means that 3.2 GHZ, FSB 1600 Yorkfield might be the fastest Intel for almost three quarters. We are sure that with its 45 nanometre process Intel should be able to get a bit higher, as Eliot managed to overclock this marchitecture with massive air cooling all the way up to 4.3GHz. At the same time we are sure that he went over the TDP top.
