Choosing a CPU for dv4t...

Hi! I'm trying to figure out which CPU I should choose for my dv4t laptop.

There are five processors available for the dv4t series.

Intel(R) Core(TM)2 Duo Processor P7350 (2.0GHz)
Intel(R) Core(TM)2 Duo Processor P8400 (2.26GHz)
Intel(R) Core(TM)2 Duo Processor P8600 (2.40GHz)
Intel(R) Core(TM)2 Duo Processor T9400 (2.53GHz)
Intel(R) Core(TM)2 Duo Processor T9600 (2.80GHz)

I want either T9400 or T9600, but the problem is the price difference between the two is $ 250 when you customize your own dv4t on the HP website. Does the 0.27-GHz difference justify the $250 difference?

I hoped to see P9500 as an option for the dv4t series because of its lower TDP. Unfortunately, HP didn't put it.

 

Between the two the T9400 is the best option. The T9600 is just not worth the premium. You would be better off spending the $200 on something else.

In reality the sweet spot would be the P8400 which would strike a nice balance between performance, price and battery life. The loss of cache from 6MB to 3MB depending on what you use the system for shouldnt be noticable in real life situations.

 

i have an AMD 5000+ Black Edition in my desktop(2.6ghz dual core), and it overclocks to 3.0ghz easy, and is stable at 3.0ghz. Its already crazy fast at 2.6, and I can't tell the difference at 3.0 but it does show up on the benchmarks about a 10% increase. I'd go with the T9400

 

Thank both of you. I'll go with T9400.

miner or somebody else, how much are TDP 25W and TDP 35W different?
I wanted and want P9500, but as I mentioned above, HP doesn't offer P9500 for some reason. I checked some websites, and T9400 and P9500 are identical except the TDP thing. Does a CPU with TDP 35W consume a lot more power than one with TDP 25W?

Thank you again. Have a wonderful day! Well... night..

 

TDP is a guideline for manufacturers to design the cooling system. Higher the TDP more cooling is required. 35W is the normal range for current Dore 2 Duo's(Santa Rosa) so not much of a difference in temperatures but the 25W's are going to run a bit cooler and provide slightly better battery life. I wouldnt term the difference as lot but there will be some benefits of running the lower wattage processor.

 

Thank you again, miner. Well... I hope 35W is just O.K. with me.
I hate HP. They don't offer the nice P9500 for any of thoese new laptop series and decided not to offer the 9600GT graphics card for dv5t!

Thank you again! Have a wonderful day!
