Confused with intel processor #, pls help!

Sorry if there has been a thread explaining the intel's numbering in their processor.
But I'm trying to compare different processor from Intel: which one is newer, which one has 64bit capability, which one is better.
Is P newer than T? which one belongs to Penryn or Montevina.

Can anybody pls explain to me or direct me to a link that helps?

Thnx in advance,

 

This Guide will help.

P-CPUs are newer than most Ts, except the ones released alongside the Ps.

P just have a lower TDP of 25W.

All Merom and Penryn CPUs are 64-bit Compliant.

The new Penryns with a bus speed of 1066MHz, Penryn QCs and a couple of budget Merom CPUs have been released recently....

 

Maybe if you post up specific processors, we can help more.

 

Thanks, Andy.
That's what I need to know.
BTW, what's the difference between Merom-2M vs Merom and Penryn-3M vs Penryn?

 

All processors starting with T- and P- are 64-bit processors, meaning they will run any 64-bit OS. The P- processors use 25 watts of power and have a 1066MHz FSB. The P- processors' clock is the same as the T- processors.

 

Merom: 4MB L2 Cache
Merom- 2M: 2MB L2 Cache

Penryn: 6MB L2 Cache
Penryn- 3M: 3MB L2 Cache

 

If its a Core2Duo , its 64bit capable.

If its a CoreDuo, its only 32bit.

 

Also if it is mobile Pentium Daul Core it is 64 bit.

 

The P series has a bus speed of 1066 (not sure if all do), whereas many of the T series (or all?) have a bus speed of 800.

 

As of now all "P" are 1066Mhz FSB.

 

t2300 isnt 64 bit capable

 

You are correct. As long as the Txxxx is Core 2 Duo or PDC not CoreDuo it will be 64bit. As said by others.

 

Pentium dual core's in socket M are 32 bit too

 

You are correct. I had a gut feeling what I was saying might be off but well I made a mistake.

To OP stay away from CoreDuo and PDC non socket P. If you do you will have 64bit.

 

T8100, 8300, 9300, 9500, X9000 are penryns. Santa Rosa
T9400, T9550, T9600, T9800 and X9100 are penryns with 1066mhz FSB. Montevina

P7350, P8400, P8600, P8700, P9500 and P9600 are all penryns with 1066mhz FSB and a 25watt TDP, 10 lower than the Montevina T series. Monetvina

Q9100, Q9200, QX9300 and QX9600 (i think thats the name) are 1066Mhz FSB Quad core penryns. Montevina.

 

Its alot easier to compare the CPUs by their cores....
Yonah: 32-bit
Merom; Penryn: 64-bit

(So, even Merom Celerons are 64-bit Compliant )

 

Interesting - are those quad-cores also mobile CPUs? I didn't know that quad cores made it to the mobile market yet.

 

Yep, mobile CPUs. They have already made there way to a couple of notebooks.

 

How do I know which one has non socket P?
Well, I think I'll just look for the Core 2 Duo or Dual Core sign and ignore the Core Duo / Pentium Dual Core, right?

For the T and P, since P is low power consumption. Is there any big difference for the battery consumption?
I notice most of the laptop ON SALE right now are using the T5800.
Should I just look for the one starting with P for future advantage?

Thanks,

 

The guide I linked in #2....compare the CPU no. in the notebook specs with the ones in the guide.

You'll find Socket P CPUs these days, Socket M and 479 are pre-historic now.

Improved Battery Consumption will be noticeable only if you run CPU-demanding/intensive tasks when on battery, otherwise slight difference.

All Core 2 Duos and PDCs can be downclocked and undervolted to save on power....

If you can find a notebook with a P8400/P8600, that'll be a good balance between CPU power, and power efficiency.

 

Just go to the wiki page where it compares current Intel Core 2 Duos to see all the 64-bit capable processors.

 

You guys helped alot

 

Very interesting - thanks for the info! Of course, at this time, games have been hardly optimized for even dual core, so quad core is probably only rarely useful, but it is certainly interesting to know that they have now made it to the mobile space.
