Intel Core 2 Duo E8400 Wolfdale against E6850 Conroe

The new 45nm CPU with new HIGH-K technology reduces gate leakage and heat. Lets compare 45ns E8400 ES VS. 65nm E6850 in benchmarks, video compression, overclocking, and power consumption.

Power Consumption

With 45nm architecture and HIGH-K tech, E8400 is rated 1.15v to run at 3GHz while E6850 required at least 1.25v at 3GHz.
E8400 is about 10% efficient on idle and 37.5% under full load.





Power Consumption tests
E8400 Idle | E8400 Load
E6850 Idle | E6850 Load

Pros:	great overclock (4G stable on 1.4v and 4.5G stable on 1.55v)) less heat (HIGH-K Tech) SSE4 (Video Compression) larger L2 Cache (6MB of L2) low price (between 230 - 180)
Cons	not available until Q1 2008
