Hi. I bought a barebone laptop two years ago after my first laptop died. Swapped all the parts over, yada yada yada. But since my laptop is in near mint condition and I want to give it another 2-3 years of life, I am looking into upgrading it.
Currently have a Pentium 750 which is 1.86ghz @ 533bus. I have 2gig ram, 80gig hd and an ati x700 which is quite decent for basic gaming.
I was wondering how the Pentium M 780 (fastest that my chipset can handle) compares to newer mobile cpus such as Solo core, dual core and core 2 duo. Since there aren't any direct comparison online (or atleast that I know of) can anyone help me out with valid information?
I basically use my laptop pretty much for everything. A bit of Warcraft 3, some torrents, surfing the web, and some photoshop work. I am using windows XP pro as well and don't really intend to upgrade to vista.
I am just wondering if it is worth putting another $100-200 into my laptop or just buying a whole new one. The two cpus that I would really only consider is the Pentium 770 and 780.
If I were to upgrade laptops, I would really be spending $800+ since I want a decent video card such as something from ATI or nvidia. None of that BS onboard.
Intel Core Solo / Core Duo are not much better than the 533 Mhz FSB Dothan as they consume more power than the Pentium M. The Core 2, on the other hand, gives about a 20% overall performance boost over Intel Core at the same clock speed.
The best possible processor upgrade for you involves getting a 400 Mhz Dothan and trying the "pin trick", which fools the BIOS into supplying a 533 FSB instead of a 400 FSB, thereby overclocking the processor-- up to 2.8 Ghz. Your milage WILL vary.
The pin mod is crap, bone it myself. The problem is that it doesn't change the "external clock" only the internal one.
This means that your NB and SB bus is capped artificially low.
I had better luck overclocking a 533 Mhz 1.73 Ghz chip. I have taken it up to 2.53Ghz using clockgen. It idles @ aroung 45degC and maxes @ 55degC full load.
Stable as can be. I suggest that if you are looking at buying a new one anyway, experiment with OCing the rig. At the very least you will learn a lot and you may get the performance boost you are looking for for free.
