Intel will launch four new Core 2 Duo processors on January 21st. Here's a short overview:
The slowest and cheapest one will be branded as E4300 is already listed by some European etailers. You can check it here. it sill run at 2x1.8 GHz will have 2 MB of cache memory, socket 775 and will cost $163 at launch. The faster E6400 will end up with 2 GH clock but we don’t have the price for this part.
Intel has two new parts branded as E6320 and E6420 - the only difference between these and the ones without 20s in the name is the cache size. The 20s one will feature 4MB of cache memory.
The 1.6GHz Core 2 Duo E4200 and the 2.13GHz E6390 without VT are both dropped from Intel's roadmap. The roadmap also shows the E63320 and E6420 but these parts are still at least four to five months away.
