Core 2 Extreme QX6850 and Core 2 Duo E6750

Shown above are CPU-z screenshots detailing the various specifications of the processors. Looking at the QX6850 first we see that it is based on the Kentsfield core, as the previous QX6700 quad core processor was. This means it is still on 65nm technology, however using a slightly higher operating voltage of approx 1.39v. All of the instructions sets are supported from MMX to SSSE3 and the CPU is 64 bit compatible. The QX6850 runs at 2.999 GHz via a 9x multiplier on a 333MHz (1333MHz) FSB and has 4 cores.

The Core 2 Duo E6750 is based on the Conroe core and runs on 1.31v and is also a 65nm CPU. The speed of both cores in the E6750 is 2.66 GHz and is achieved by combining an 8x multiplier with the new 333MHz/1333MHz front side bus.

Cache levels in the QX6850 come in at 4x 32KB of data and instruction cache (each core having its own instruction and data cache) and 2x 4mb of L2 Cache with two cores sharing 4mb. These specifications are cut in half for the Dual core E6750 which features 32KB of L1 data and instruction cache per core and 4mb shared between the two cores.

The actual hardware looks identical to the Core 2 CPU’s which have been released before, we see above the E6750 from the top and then flip it over to see the underside which reveal the 775 contacts. The final picture above is the new 1333MHz CPU alongside the 1066MHz X6800 dual core CPU, there is no difference in appearance.

Nothing new with the Quad core processor either and the pictures above show the new QX6850 alongside the QX6700 which was released back in November 06.
