Core 2 Processor Versions

Game Over? Core 2 Duo Knocks Out Athlon 64

Four mainstream and one high-end processor models will be released to the market on July 27. Core 2 Extreme X6800 is the cavalry (expect to spend one grand on it), while Core 2 Duo E6700 to E6300 represent the main strike force.

Core 2 Model Clock Speed Multiplier Front Side Bus Speed L2 Cache
Extreme X6800 2,933 MHz x11 266 MHz (FSB1066 QDR) 4 MB
Duo E6700 2,666 MHz X10 266 MHz (FSB1066 QDR) 4 MB
Duo E6600 2,400 MHz X9 266 MHz (FSB1066 QDR) 4 MB
Duo E6400 2,133 MHz X8 266 MHz (FSB1066 QDR) 2 MB
Duo E6300 1,866 MHz X7 266 MHz (FSB1066 QDR) 2 MB

All Core 2 processors run at a Front Side Bus (FSB) speed of 266 MHz now, whereas most Pentium 4 and Pentium D models typically run at 200 MHz. At four data transfers per cycle (quad data rate mode) this results in a marketing-friendly FSB1066 bus speed, delivering a 8.5 GB/s bandwidth. Except for the entry level, all models have a 4 MB L2 cache that is used by both processing cores. All processors support Intel's 64 bit instruction set (EM64T), the streaming extensions (SSE2 and SSE3), the virtualization technology (VT) and the Execute Disable bit (XD). In addition to these functional features, all models support the latest thermal and energy management features such as the Thermal Monitor 2 (TM2), the Enhanced Halt State (C1E) and Enhanced SpeedStep (EIST).

Core 2 Extreme X6800

The Extreme Edition processor is the only version that allows the user to alter the multiplier, so she or he can overclock or underclock it easily.

Core 2 Duo Series

Core 2 Duo runs at between 1.86 GHz and 2.66 GHz.

    I wonder how many computer actually have the SpeedStep or Cool & Quiet enabled.

    90% of them considering a tiny amount of the market is overclockers who turn it off...
