So what do we have? Better clock speed with no extra heat (thanks to the new 45nm fabrication with high-k based gate), more L2 cache new micro architecture and a smaller size die which means cheaper or the same prices as the older model.
Intel will introduce three models in the Core 2 Duo E8000 series:
Core 2 Duo E8200 running at 2.66 GHz with an 8x multiplier
Core 2 Duo E8400 3.0 clocking at 3 GHz with a 9x multiplier
Core 2 Duo E8500 clocking at 3.16 GHz with a 9.5x multiplier
All of the Core 2 Duo E8000 series will have 6MB of L2 cache and 1333MHz FSB.
The benchmark testing showed that as expected the Core 2 Duo E8000 has better performance, over clocks well and does not cost any more.
So, its seems that Intel second generation of the Core 2 Duo will perform better then the first with no extra cost.
