    Hi,

    I want to buy new SONY laptop Z series , it's come with P8800 processor , and I have my old laptop (damaged ) with T9300 processor (working fine).

    I interested in T9300 because of the cache memory size (6Mb) and 800 FSB , but P8800 has 3Mb cache memro and 1066 FSB .



    Do you advice me to replace the P8800 with T9300 ??


    Regards,
    alhaim

    What are you using the computer for?

    If your uses aren't CPU intensive then you won't notice any performance difference from both CPUs.

    And note that changing the CPU will most likely void your warranty with Sony.

    Your warranty will be voided, but as Forever_Melody said, do it only if you do CPU intensive stuff on your laptop.

    You'll hardly see much difference.. somemore P8800 has higher clock speed than T9300 and also Higher FSB speed. If u really want an upgrade , look at a Vaio Z with core i5 or core i7 processors.. also it depends on ur uses. You need to give us some more information.

    but what about the cache memory , it's double in T9300 means more faster with application .. regarding the warranty , no problem because the replacement will do with the shop under its local warranty for the laptop .

    my use is normal , Internet, office application , games (not much) and movies , but I need to speed in the multitasking when I open many application at same time,

    also don't forget the speed at booting .

    I see. Many here won't suggest you to upgrade as you lose your warranty.

    I must ask you one another question, what is size of your RAM ?

    Multitasking is a property of RAM, not CPU.

    Fast booting of the OS and applications is a property of the HDD.

    None of the above listed uses will see any benefit from a faster CPU.

    Well, that was why I asked his/her amount of RAM :)

    im pretty sure you won't notice much difference in terms of performance, i think the main thing you will notice is power consumption because the P architecture is based on newer technology and draws less energy

    As far I as read, at idle the power consumption should be about the same. Long time underload makes diffrences, not big tou.

    They are both 45nm penryns. The T9300 was designed for Santa Rosa chipsets which is why it runs at a lower 800Mhz FSB but higher multiplier than a T9400-2.53. The T9300 is rated at 35W TDP because of it's larger cache.

    The T9300 would be a better choice if you might wish to do a FSLx PLL pinmod. Ie: T9300-2.5/800 to T9300-3.33/1066.

    A T9300 from a P8800 is not an upgrade it is a downgrade. Clocks are king. You wanna go a little lower clock for more cache? No not a good idea. Add to it the slower FSB? That affects the memory bandwidth and P8800 wins. The P8800 seems to vary from 25w/35w TDP, I would hope you have a 25w TDP but even if not I would not do.

    Double the cache adds what 2% to 4% at best. Your clocks also offset too some extent. In many apps the L2 diff makes 0% diff.

    I would not even consider.

    4GB DDR3

    so what is the main job of the cache memory if (as u said ) it's not related with multitasking or application or even fast booting !!

    Well, 4GB DDR3 and P8800 should be enough for multitasking.

    Do you know what your RAM -modules are running at?
    (800Mhz or 1066Mhz ?)
    IF they are running at 1066Mhz, then you'll actually slow down your RAM with T9300.

    It's related obviously, but a lot less so than the components I've listed. Those things will more likely than not bottleneck either multitasking or fast booting before CPU cache ever does.

    Depending on modules , i would say 1066MHz is most likely... OP , just stick with P8800.. its really not worth getting ur warranty voided... the P8800 is better and runs cooler than T9300.. i would recommend u sell the T9300 instead and get more RAM or best of all an SSD... ur system would be way faster than.

    I would suggest SSD -Drive instad of RAM.

    My suggestion:
    Upgrade to SSD-Drive if you want short bootup-time and cut the loading times down. This will also give you better battery time.
    As next step you can upgrade your RAM to 1066Mhz if it already not have 1066Mhz modules. (ONLY IF YOU NOT CHANGE YOUR CPU WITH T9300) But as Sean said, most likly you have 1066Mhz modules.
    4GB RAM is enough for most of daily-users, single 4GB sticks is also too expensive for now...

    Your decision...
