notice difference between t6400 and p8400?

well i wanted to know if there is much difference between a t6400 and a p8400. i have read the ultimate cpu guide and it helped a little but didnt list the t6400. there probably is a difference in speed like if u run tests but i am wondering will i notice it if im browsing the web,listening to music, and play a pretty small game. its like counter strike but korean. also while using it at college.

also i need help with what i should do
well first of all i have no idea where to post this...so here it goes
i bought a studio 1537 from the outlet for 484 dollars with the specs of p8400,3 gigs ram, 250 gig hd, lowest resolution scree, webcam, fp reader, and the 4500mhd gpu. i have heard the studio 1537 has had many problems so im asking, should i return it before its too late or i mite be able to sell it for 600, make 100 profit and then a new laptop. some laptops i was thinking about were the
lenovo y430 with t6400,x3100gpu, 320 gig hd, 3 gigs ram.

lenovo r500 with the p8400,4500mhd, 1 gig of ram, 160 gig hd.

or a dell lattitude e6400 which would have atleast a p8400, webcam, and it would probably come with little hd space cuz its from the outlet, and like 1 gig of ram but i can always upgrade the ram by getting a cheap kit from newegg for the e6400 and r500

i was also looking at hp like the dv4t or dv5t. not sure about hp though.

so basically im asking should i keep the studio or get a new laptop? i want to factor in quality, customer service when something goes wrong(rite now dell is proving their consumer products customer service sucks), and price. i want to spend little as possible and try to get atleast medium high factors.

 

Yeah, the T6400 doesn't have like an official spec sheet yet... but apparently it IS officially released: http://ark.intel.com/cpu.aspx?groupID=40479&code=t6400. It's a 2.0GHz, 800MHz FSB Penryn with 2MB of L2 cache, so it probably performs just shy of the T8100 which in turn probably performs just shy of the P8400. So you'll see a significant difference in benchmarks, but not under the light use that you mentioned.

EDIT: It's also a 35W part, so you're going to be dumping more heat than a P8400 at load.

 

k thx and can u help me on what i should do...go back to first post

 

I can't see the difference between 2GHz (my previous notebook) and 2.4GHz (current notebook) in everyday usage.

As already noted, the P series CPUs use less power and produce less heat. While this is most noticeable under full load (but might get fixed by undervolting) the P series also use less power under light usage and therefore help to maximise the battery time.

Advice on selection of notebooks belongs in another forum.

well i was planning on the t6400 on the ideapad y 430 but still seems a little expense and was wondering how the pentium dual core t3400 compared to a t6400 and p8400. since its still a pentium dual core i dont know how old that is.

 

The T3400 is from the previous (pre-Penryn) 65nm silicon with only 1MB cache.

Perhaps a chip that would have been a T7400 expect that too much cache was defective. Intel are good at creating new (usually cheaper) CPUs from the bin of defective parts - it's better than chucking them away.

The 1MB cache may limit performance under some situations, but still offers more than most users need.

There is no one a t3400 could have been a t7400 because a t7400 is socket M t3400's are socket P

 

lulz..okay. You could say T5850 instead of the T7400.
The T7400, T5850 and T3400's CPU core is the same. Only the PGA is different. Not a big deal for intel to change a CPU's PGA. -.-
Though I've never heard/read about the defective cache thing till now. o_0

 

Just note that the P8400 has Intel-VT the T6400 has not.
They are both 64 bit but if you want virtualisation for using emulators or the XP version of Win 7 then it is a good idea to check out the difference.
I bought a Samsung Q210 with T6400 and I am being asked to pay over GBP300 to have it upgraded to P8400. It also is 25W instead of 35W so the battery will last longer.

 

Used the 2 CPUs in different (yet similarly specced) computers in the right environments before (I guess, Photoshop CS3, Maya 8.5, XSI Softimage 7.0, Flash CS3).

Not much different on games though, if not any (I play mostly old games though)

The T6400 is noticeably slower. I'd go for the P8400 for its lower TDP and >10% (based on Passmark ratings) performance difference over the T6400.

Edit: Oops, didn't notice the original post date. Nonetheless, I just hope that what I mentioned here helped.
