Today Intel Officially Announces Core 2 Duo And Core 2 Extreme

Today in the midnight (local time) Intel officially announced its Core 2 Duo and Core 2 Extreme desktop processors. We've written much of them already, so we'll just revise that information. The key differences of the new architecture from the "ideologically closest" Intel Core Duo (Yonah) are as follows:

  • Improved instruction decoder extended to 4 decoders of x86 macroops (vs. 3 of Intel Pentium M / Core Duo)
  • 128-bit SIMD instruction performance of 1 instruction per clock in each execution unit (twice as faster as Yonah)
  • Improved memory operation and hardware prefetch mechanisms
  • L2 cache is dynamically shared by both cores depending on load (as seen in Intel Core Duo)
  • Further improved energy saving
  • A new SIMD instruction set SSE4.

The first Core 2 processors will be:

  • E6700: 2.66 GHz / FSB 1066 / 4MB L2, $530
  • E6600: 2.40 GHz / FSB 1066 / 4MB L2, $316
  • E6400: 2.13 GHz / FSB 1066 / 2MB L2, $224
  • E6300: 1.86 GHz / FSB 1066 / 2MB L2, $183
  • Core 2 Extreme X6800: 2.93 GHz / FSB 1066 / 4MB L2, $999

The most junior of the series, Core 2 Duo E4200 (1.60 GHz / FSB 800 / 2MB L2) is not yet to be announced.

Speaking of sales delay on July 23 to 27, on July 23 online stores will start accepting orders, while Intel will officially launch sales on July 27.

We recommend you read our preliminary reviews of Core 2 Duo E6400 and E6700 as well as Core 2 Duo E6600.
