h10010.www1.hp.com/wwpc/me/en/sm/WF06b/321957-3219...


The only question is: not enough to date two cores (whether this notebook faster old).


In the old Core 2 Duo T6500 (2M Cache, 2.10 GHz, 800 MHz FSB):

The new Core i7-2640M Processor (4M Cache, 2.80 GHz):
ark.intel.com/products/53464


Will be a noticeable difference in performance? Or the flea?

The MC today is not very important. Here 4M cache is good.

In General, as you know "the System works with the speed of the slowest element" so to compare the two systems only on the percent that's rude.

Say, on the visual performance much noticeable effect replacing the HDD to SSD, rather than a replacement C2D to i7.

I believe to change the hardware more often than every 3-5 years is the indulgence consumer instincts and paying tribute to the transnational corporations. In General, is a bad idea.

Mobile ci7 features from the c2d in the first place less power consumption. And in the laptop it is much more important than anything else.

And performance any good table stone five years ago will beat any laptop with a large margin.
Any good desktop graphics card from five years ago will beat any mobile in all respects.
Any good monitor all the same it is more pleasant to the eye than any laptop.
And any normal keyboard is anyway more convenient. And for maniacs there is even a small keyboard with tachpadom.
And while it all cooks hands, not humming turbine and not zastavlyaet or to keep your hands above your head or slouch when referring to buttons.

Laptops are not for high performance do and not for games and not to watch a movie and not for convenience.
And to be able to take and carry.

The biggest jump in performance since the first Core Duo, felt when moving from HDD to SSD, not when you change the CPU. Now, working with HDD system occurs about the same weird nostalgic feeling of discomfort, as when using a CRT monitor. PHPStorm, Eclipse, two working new path: Win and CentOS with two DBMS — feel on Core2Duo 1.86 GHz + SSD is absolutely free, so find no reason to change the stone. My opinion: try to start to change the screw.

Second, most of the inhibits in the system screw. Then from the task can slow down graphics. Again solves the memory.

It all depends on what you need the laptop. Based on the fact that it's faster to compile, the difference in speed I would say is not very big, but to pinch the video, then there is the difference.

as the user HP EliteBook 8560w (XU085UT) I can say that the powerful percents without the SSD for compilation of little help. But SSD wonderfully large speeds up build times so 3-4.
