p8400 vs p7750

im interested in difference between those 2. they both have 2.26ghz, 3mb l2 cache and 1066 fsb? where is the difference?

 

I cannot find a p7750 is this correct?

EDIT : cannot find any INTEL info on this , but the model number p7750 is mentioned a couple of time in a Google search.

 

hp pavilion dv7-2170 has it which im planning to buy so i was interested in difference. or amazon made a typo

 

I think he means P7550, and there is no major difference.

yeah, it should be a P7550....

The only difference being lack of vitualization support in the P7550.

 

Looks like the p7550 does not support VT- Vitalization , important if you want to install Windows 7 and use Xp mode.

 

im a noob so i dont know what that is .so is it very important for gaming?

 

It just if you need to run a game or some software that is not compatible with win7 , it emulates Windows Xp for you.

 

Hi there!
They are exactly the same thing.
I think Intel renamed the P8400 to P7550 when the Montevina Plus update came, because the P8400 spot was taken by the P8600, and the P7450 was almost discontinued.

Basically same thing, same specs, same everything, different name, and no VT support

 

but the P7550 does not support VT when the P8400 does so they cannot be the same just with a different model number.

 

Are you sure the P7550 does not support VT?
As far as I knew, it was a renamed CPU.

 

I thought running anything through a virtual machine would make it very slow compared to running it natively. I also thought that those programs would not be run through a virtual machine but through compatibility mode, something completely different.

The vast majority of user have no need for VT, so don't even think about it. Unless you know you need it you don't.

 

look at the intel spec sheet.

The OP said he did not understand what VT was so i told him a simple as possible , the main feature in Win7 is the Xp mode , you can use it to run virtually any other 86 compatible software but that`s another story.

 

The "XP mode" doesn't come with windows 7 but is an add on that you have to pay for unless you have the ultimate edition, in which case you can download it for free. He asked if it was important to him as a gamer, and the answer is no. A simple explanation of virtualization would be that it allows you to run an operating system within another operating system, allowing you to run any software that the operating system can support, albeit at much reduced performance.

 

I thought it was available on the Professional and Enterprise editions as well, free of charge. Here's a quote from Microsoft's Virtual PC website:

But chances are, you will never use it as a gamer, so the P7550 is more than sufficient for you.

 

tnx guys. so it isnt important for me. just one more question.

is there a big, or noticable difference in t6500 and p7750.
t6500 has 2.1ghz,L2 2MB cache and 800mhz fsb and you know about p7750. im interested will i notice a big difference in gaming if i pick t6500 + hd4650 or p7750+hd4560

 

Doubt there would be any significant differences. How much is the upgrade? <$50 maybe worth it but even then, I'd probably stick with the T6500.

 

The performance difference between the T6500 and the P7550 are not significant at all; save some money and get the T6500.

 

No, you wouldn't notice a big difference in gaming unless you had something more powerful than the radeon m 4650.

 

the performance difference hardly justifies it, but power consumption does. there is about ~40% difference in power consumption between these two chips and i did not realize that when i made my decision. now i regret getting the t6500 over the p7xxx series. i'm trying to make my notebook use minimal power and as quiet as possible, and i realized i made the wrong decision on processors to save that $50

 

Where did you get those numbers from?

 

cause im thinking over sony vaio fw 455j (t6500 hd4650 320gb hdd 7200rpm) or hp dv7 1270us t7750 hd4650 500gb hdd 5400rpm. guess ill have more use of faster disk then bigger cache and higher clock.

 

There is no difference in power consumption. TDP is more of a marketing thing than anything.

 

They are basically the same, bottleneck is mostly the GPU wheb high-end gaming and the HDD, I would say that if difference in price is negligiblen go with the higher clocked CPU, if only negligible, if not, then it isd notworth it. On the other hand, the faster drive helps better than the faster CPU .

 

well i just based it off the TDP of the chips. the Txxxx series is 35w, and the Pxxxx series is 25w. a difference of 10w of 25w from the p8400 is ~40%, hence why i put "~" to mean around that much. It may not be this high as some imply, but surely the T series shouldn't consume less energy than the P series.

i just got a T6500 over the P7350 because performance difference was only negligible, but i didn't know about the TDP difference at the time. my T6500 freakin idles at ~50C AFTER it's been undervolted to the lowest possible

 

The T series can consume less power than the P series. It's all in the marketing.

 

WhiteFireSnake, have you done a clean install?
Have you checked for running processes that shouldnt be there?
Do you clean the laptop regularly?
Is it on a flat surface?
It is strange that it idles at 50C, what laptop you have?

 

I've heard of intel renaming a processor with half the cache disabled, like the pentium dual core and the bottom line c2d, but not over a 2 chips where the only difference is virtualization...
i think the guys down at intel are getting desperate. Not sure why tho..
