Hey, cheers for your reply. Looking at it, I think you're right. Until the Broadwell comes out, I can upgrade the e6430 to be, as far as I can see, in terms of some hardware at least, superior or equivalent to the e6440 (without replacing the e6440's processor).

Hello guys, I am considering buying an E6440 to replace my E6430. However, I have some concerns, and a question. In every respect, except the possible 512gb ssd, the e6440 seems to be worse than the e6430. The best processor for the e6440 is only dual core and is clocked at just over half of what the best processor for the e6430 gives (5000 vs 9000), which I have. I have read that it is more power efficient to have more cores run at a lower level than fewer at a higher level, and reviews confirm that the e6430 is quite power hungry. The graphics card, despite being 2gb in the e6440, is, noticeably worse than the 1gb graphics card in the e6430 according to passmark (451 vs 630). Finally, it doesn't look like the newer latitude has a LED screen, like the retina display on the macbook. Reviews i've read say that the display is actually quite poor on the e6440, but my e6430 display is quite good. My concern again here is power consumption. A OLED screen could be set to all black with white text for certain applications, or get a black background. Lowering the brightness would reduce the power consumption (and if I recall correctly, this is not entirely the case with LED backlit screens, because the backlight never goes off.). Therefore, if any of you already had the e6430, would you consider buying the e6440? Assuming I didn't want to void the warranty by tinkering with the insides. Thanks, and apologies if I've asked any questions that've already been answered.
