| Intel’s latest roadmap adds two more processors to the upcoming lineup. The roadmap reveals early plans for the Yorkfield-based Core 2 Extreme and another Core 2 Duo E4000-sequence processor. |
With Yorkfield, Intel differentiates the Core 2 Extreme and Core 2 Duo models by the front-side bus speed. Intel Core 2 Extreme Yorkfield processors will have a 1333 MHz front-side bus, continuing on where the Kentsfield Core 2 Extreme QX6850 leaves off. The quad-core processor supports Intel VT, Enhanced Intel SpeedStep and Intel 64 and Execute Disable Bit technologies. Intel leaves TXT technology out of the 45nm Core 2 Extreme however.
Intel’s Core 2 Duo E4000-sequence receives a speed bump in Q4’2007. The new Core 2 Duo E4600 clocks in at 2.4 GHz and remains on an 800 MHz front-side bus. Aside from the speed bump, the Core 2 Duo E4600 is no different from other Core 2 Duo E4000-sequence models.
