Celeron Dual Core vs Pentium Dual Core (Speedstep)

How bad is

Intel Celeron Processor T3000 Dual Core Series ( T3300 @ 2.00 GHz)

comparing to

Intel Pentium Processor T2000 Dual Core Series ( T2410 @ 2.00GHz)
Intel Pentium Processor T3000 Dual Core Series ( T3200 @ 2.00GHz)
Intel Pentium Processor T4000 Dual Core Series ( T4200 @ 2.00GHz)

in terms of lack in celerons:

Enhanced Intel Speedstep Technology

It's fine for me that all of them didn't have "Intel Virtualization Technology (VT-x)" and have different FSB, but isn't this anti-heat-and-noise-and-battery-saver feature essential for laptop? Most of cheap offers have celerons, bur for me they looks like bad compromise, or I overestimate value of this feature?

 

The only thing you will notice is not performance (they are all 2GB 1MB cache models), but lack of battery life with the Celeron model.

The most efficient should be the T4200 with its 45nm tech. It should also 'bench' the best because of the 800 MHz bus speed, but I don't think this will be noticeable in the tasks that would be typical for this level of processor.

 

I was not asking about performance or efficient, I am interested in HEAT and NOISE factors - is it different for this models?

 

Efficiancy ~ Low heat and noise. I highly suggest to not get the celeron as speedstep is an important feature that reduces heat and power consumption (and fan noise). The other ones... If you can, try and get the T4xxx because it's 45nm and so should be an improvement over the other ones, but if you don't really care, just get the cheapest pentium.

 

if u want to choose in between these processors, get the T4200.. higher battery life and newer.. don't even think of buying celerons... they're the lousiest CPUs ever... but if u can , why not go for a proper core 2 duo like T6000 or P7000 or P8000 series CPU laptops..

 

sean473, why not go for a proper quad core?

 

well i would personally go for a quad core if u had cash... it only has a TDP of 10W more than the core 2 duo and pentium dual core laptops... battery life will be slightly les but... if u live in america , its quite easy to get a cheap quad core laptop like the Hp Dv6t quad edition... costs about $1000 and u can get it cheaper with cashback and all... its more expensive in europe and asia...

 

Ultimately the caliber of performance that you're looking for depends on your computing requirements, not on simply choosing the most powerful CPU money can buy. Given that very few programs and only a few high-end games require a quad-core CPU nowadays, a quad-core computer is not entirely practical as it raises other issues; increased heat, increased power consumption, and increased cost.

I would strongly recommend looking at a high-end P series or T series Core 2 Duo, the main difference being that the P series have a 25W TDP vs the 35W TDP of the T series. Given that these models deliver excellent performance for all but the most demanding tasks (such as scientific programs, CAD, multimedia editing, certain game titles) and are still cost-effective, these are the best options at the moment.

EDIT: Even if you're looking at budget CPUs such as the Pentium dual-core, a low-end Core 2 Duo such as the T5500 or T6600 is still the better option from a cost and performance perspective. As for the Celerons, there is absolutely no reason to consider them.
