I found this on notebookreview.com
Intel on Sunday announced that its new 64-bit dual core chips for laptop and desktop computers will both be called"Core 2 Duo", hoping to reignite interest in its products amid tough competition from rival Advanced Micro Devices (AMD).
The mobile processor microchip is known by codename "Merom" while the desktop processor is codenamed "Conroe". Intel will also introduce a premium processor to be dubbed "Core 2 Extreme". Conroe processors should begin shipping in July while the Merom notebook processors should become available in August.
The mobile processor series should have a T5000 line of processors that will have 2MB of L2 cache and a higher end line T7000 that will have 4MB of L2 cache. Clock speeds should match that of currently available Core Duo processors (about 1.66GHz - 2.13GHz). The big change between the currently available Core Duo processor and Core Duo 2 is that the Merom Core Duo 2 will support 64-bit instructions. Below is a list of 4 processors we believe will launch in August:
T5600: 1.83 GHz, FSB667, 2 MB L2 cache, $241 at launch
T7200: 2.00 GHz, FSB667, 4 MB L2 cache, $294 at launch
T7400: 2.16 GHz, FSB667, 4 MB L2 cache, $423 at launch
T7600: 2.33 GHz, FSB667, 4 MB L2 cache, $637 at launch
Although Intel is predicting August for a release of the Merom processor, it will not arrive in shipping notebooks in time for the back to school sale period which starts now and runs through until the beginning of August. The processor will probably provide about 10 - 20% performance boost over current Core Duo processors, but if you need a notebook now it's probably not worth waiting. Current Core Duo prices have dropped making notebooks with the current processor a very attractive buy.
Lookie, I'm not plagarizing.
