Core 2 @ 1333Mhz FSB tested
@ 2007/03/11While Intel Core 2 Duo E6050 family enjoy speed upgrade from 1066MHz to 1333MHz FSB, bandwidth is elevating 25% but no significant help to improve overall efficiency, therefore, Core 2 Duo E6850 frequency will be reduced to 7x (2.66GHz/4MB L2/13 33MSample/s FSB), as compared with the same time connections FSB 1066MHz FSB but only Core 2 Duo E6700. Test results found that most effective growth of less than 1%. Only memory tests have significantly higher reading and writing progress.
Intel is keeping 1066FSB parts around until Yorkfield/Penryn, namely with Kentsfield. Probably explains why they are giving a 50% price slash for the Quad Q6600 down to $266 in the third quarter.
