Is there a ranking of Intel Core processors?

Hi,

when I am configurating my laptop at the online store www.znote.dk I can choose among a lot of different Intel processors, but I have no idea how they should be ranked. I need to compare the speed of the processors, so I can choose the best price/speed combination. Is it possible to find a ranking somewhere, or maybe you can tell. The list I can choose from:

1.66 GHz Intel® Core™ Solo T1300
1.66 GHz Intel® Core™ Duo T2300E
1,60 GHz Intel® Core Duo T2050
1,66GHz Intel Core DUO T2300 FSB 667MHz
1,83 GHz Intel® Core™ Duo T2350
2,00 GHz Intel Core DUO T2500 FSB 667MHz
2,33Ghz Intel Core DUO T2700 FSB 667MHz
1.83 GHz Intel® Core™2 Duo T5600
2.00 GHz Intel® Core™2 Duo T7200
2.16 GHz Intel® Core™2 Duo T7400
2.33 GHz Intel® Core™2 Duo T7600

The prices differ a lot, and the price is not following the list above (that is the price is not increasing from top to bottom, for all of them)

 

Order according to the fastest to slowest...
2.33 GHz Intel® Core™2 Duo T7600
2.16 GHz Intel® Core™2 Duo T7400
2.00 GHz Intel® Core™2 Duo T7200
2,33Ghz Intel Core DUO T2700 FSB 667MHz
1.83 GHz Intel® Core™2 Duo T5600
2,00 GHz Intel Core DUO T2500 FSB 667MHz
1,83 GHz Intel® Core™ Duo T2350
1,66GHz Intel Core DUO T2300 FSB 667MHz = 1.66 GHz Intel® Core™ Duo T2300E
1,60 GHz Intel® Core Duo T2050
1.66 GHz Intel® Core™ Solo T1300

Do note that the Core 2 Duo's are 64bit capable while the Core Duo and Solo are 32bit only. Also the Core Solo is a single core processor while the rest are dual cores. There is no difference in terms of performance between the T2300 & T2300E. The only difference is that the T2300E lacks Virtualization support.

 

There is usually an obvious price/performance sweet spot.

Unless it has changed recently, it's the T7200.

You get the 4MB cache, and dual core 2GHz is plenty fast.

 

Is the T7200 really that much better than the T2700?

 

Yes. The Core 2 Duo is based off the newer Core architecture. The Core Duo is based off Pentium M. In terms of performance, Core 2 is better.

 

clock for clock, core 2 duo is 20% faster than core duo overall in benchmarks

 

I thought the difference was only 10%?

 

Completely incorrect. The Pentium-M was initially based on the 'Banias' (130nm) and 'Dothan' (90nm) cpu cores. The Core architecture is based on an entirely different technology, the 65nm 'Yonah' core, designed specifically for the 'Core' line of cpus. The later Core 2 cpus are based on the 'Merom' core and have, clock for clock and assumimng the same amounts of level 2 cache just under 10% increase in performance due to the newer technology.

Again completely incorrect. Assuming the same amount of level 2 cache, Core 2s have under 10% performance gain over the original Cores. The T7*00 series of Core 2 Duos have double the level 2 cache of the other Core 2s and original Cores and as such the performance increase is greater.

The sweet spot for high performance is the Core 2 Duo T7200 at the moment, but even this is only worth it for newer games and cpu intensive tasks.

 

So I was right!
