Centrino only CPU in notebooks?

A friend of mine has an ASUS Z83V and wants to put in a P4 2.8GHz, 512KB, 533MHz FSB, Socket 478 processor.

I told him that even though it might fit, it probably would not work.

Would it or not and why?

Thanks, Nick

 

you gotta have the matching sockets

 

Pretty much any Centrino CPU is going to outperform a P4

 

The heat that is going to be produced by the P4 2.8GHz even if the processor is pin compatible.

 

Wasn't there a threat comparing the performances of Centrino cpu's and P4's?

 

1. The Pentium M socket on the Z83V is 479, so the processor is not physically compatible.
Even if the socket were compatible:
2. Any Pentium M starting from slighly over 1GHz would outperform a 2.8GHz PIV; my 1.6GHz Pentium M outperforms a 3GHz PIV by about 15-20%. To see why, remember the cache on the PM is 4 times larger than that on the PIV, and that's what matters.
3. The notebook cooling system were unlikely to be able to handle the heat developed by the PIV processor.

In conclusion tell your friend to forget about it.

 

Agreed, don't do it...

But I have to say over the years, I always hated how there were no Pentium 4 Desktop vs. Centrino comparisons I could find...Centrino is just an Intel brand name for notebooks with built in Intel wireless capabilties and a Pentium M (sometimes called PentiumM 4 or even Pentium 4) CPU. My laptop had a Pentium 4 Desktop CPU, 2.66 GHz HT and its knocking the socks off my CoreDuo 2 GHz on single process tasks, real world tasks - even launching Windows XP (Not Vista!) was a 10 seconds+ faster before, even with an older system, slower HDD and slower and a lot less RAM....

Why would he want to use an inferior CPU? The P4 architecture was such a disaster that intel had to revert back to the P3 architecture for the banian/sonoma...

It would not fit in a 479 pin socket, thankfully

 

Actually, Pentium M, 4M and 4 are three different processors, and P-M was never called P-4M or P-4. Tom's Hardware Guide did in fact do a comparison about 1,5-2 years ago, here's the link. And if your P4 is performing better than your C2D, something is not right with your new laptop, so you should have that checked out (or do it yourself).

 

um in single core use
your 2.0 c2d is faster than a 3.8 ghz p4

So theres no way your 2.6 ghz p4 can even think about being faster in any possible thing. Calculating pi its about half the speed. So you have some issue.

 

Agreed with the others, the CoreDuo should knock the socks off the PIV.
As I said before, even Pentium Ms do that for lower clock speeds than 2Ghz.

When launching Windows/applications that put strain on the HDD, you might get a slowdown on the laptop; it would be because of the lower speed of the laptop HDD.

 

As I said the HDD in my old system was always slower, and it still boots up faster than my new laptop even with the 4200 rpm it originally came with (and that I put back into it - my Z96JS has a 7200rpm drive).

It wasn't anywhere official that called it a P4M, it was stores like BestBuy, and small computer manufacturers, or posters, who kept getting them confused.

The P4 I had was a Pentium 4 533 FSB HT 2.66 GHz. It definitely boots faster, even now, than this one, and I've done all the enhancements to both of them. But even now, I handed the old laptop over to my mother as her main system and it still boots up in about 39 seconds, while my new one boots in approximately 47-50 (and she has all sorts of crap in msconfig, I have none). It also would load save games and a bunch of games faster. Super Pi it was slower by 30+ seconds. Not sure if there's something buggy about the drivers or what, but my ECS G732 in a bunch of tasks is outdoing my Z96JS...

I'm not trying to justify anything, I'm just stating what I saw, if you have any more tips on how to get my Z96JS working faster I'd be greatful to hear them (I've already used TweakXP to enhance my bootup time and reorganize boot files, as well as keeping the system pretty well defragged)

The Pentium M wasn't faster, because of its cache. Remember, even a slowly clocked Pentium M would outperform the fastest Pentium 4 processors, which had the same amount of cache. The blistering speed at such a low clockspeed came from the architecture. NetBurst (Pentium 4 architecture) offered its "performance" at high clockspeeds, because of the long 20 stage pipelines. Pentium M had stages that were a little over half that (12 to 14), and this meant it could do alot more processing, at a lower clockspeed. In simple terms, Intel wasted alot of time and resources in Netburst, but it did benefit the marketing division, because they advertised their products on sheer clockspeed.
