Intel Core 2 Duo E4400 processor is a low-end product equipped, like E4300, with an ''old'' 800 MHz FSB, 2MB shared L2 cache, and it doesn't support virtualization. But! Its clock rate is 200 MHz higher than that of E4300. Because of this... It's also higher than the clock rate of Core 2 Duo E6300, the junior product of E6xxx series! Therefore, E6300 merely offers questionable (from the end-user point) virtualization support and 1066 MHz FSB. And E4400 has ''just'' 140 MHz higher clock rate. Actually, we can draw conclusions already now, but let's still see what test results are.
