First Step: 400 MHz FSB And 3.8 GHz
Ad
Our Core 2 Duo E8500 processor reaches its 3.16 GHz core clock speed by multiplying the system speed of 333 MHz times 9.5. In the first step, we increased the bus speed to 400 MHz (FSB1600), which will be the default clock speed for the next Intel chipset generation (X48 and P45 aka Eaglelake and Bearlake). Multiplied by 9.5, this resulted in a core clock speed of 3.8 GHz, which ran absolutely stable at all times.
A clock speed of 3800 MHz was not much of a problem for our Wolfdale sample. The Gigabyte X38-DQ6 automatically increased the supply voltage from the default of 1.225 V to 1.345 V.
We set the memory to a 1:1 ratio in order to stay at the default 400-MHz clock speed of DDR2-800.

from that view point i would have thought it would have made sence to at least include the 8200 for comparison, If not have done the whole article on it instead of the 8500. Or am i missing the point?
Intel has no dedicated inter-connect, no onboard MMU. All inter-core communication for both dual and quad-core CPU's has to go via the FSB. Intel is late catching up because it got complacent.
Also, AMD CPU's at the bottom end still overclock well and are very cheap. I don't think everything is in Intel's favour
Socket 939 90nm Athlon64 3200+ (2.0GHz) can hit 2.7GHz or more on air. Same for Socket AM2 65nm Athlon64x2 4000+ (2.1GHz).
..not bad considering it's a generation before C2D.

Am I wrong in thinking the intel dual core does have inter core communication on chip. It is the quad core that communicates via the fsb for but only between the two core 2 duo dies.
