2.2GHz vs. 2.4GHz

is there difference significant?

pros: faster

cons: cost more? that should be it right?

 

yea the difference isn't that big.

 

The price difference between 2.2 and 2.4 is probably too high to justify the barely noticeable performance increase.

 

exactly. significant cost per speed increase. keep that in mind.

about 160% as expensive for 110% speed - comparing 2.4 ghz to 2.2 ghz chip. the cost obviously depends on where you buy it, because individual laptop manufacturers will charge you whatever they want. i pulled those numbers off of newegg.

 

how much more power will it consume? heat? beyond price would there be any other problems?

would the benefits (faster, futureproof) outweigh the cons (power consumtion, heat)?
(again beyond price)

 

The heat and power differences between 2.2 and 2.4 would be very small to be honest

 

And the future proofing is also negligible.

 

The 2.2ghz is a better deal. The premium for the 2.4ghz outweighs the performance gain.

Just one guys opinion.

 

but beyond the cost,

does the pros (speed increase and futureproof) outweigh the cons (battery consumption + heat)?

 

If you take a look at this chart you'll see that in a couple months intel is going to release some additional mobile cpus. The point being that the idea of "future proof" is a myth.

Theres always going to be something higher, newer, and faster. You should make a decision on hardware based on your own personal needs. If you feel like you are going to need a 2.4ghz cpu then get one but i don't suggest you get one because you think thats going to be one of the best cpus available.

I can afford the T7700 just fine but theres a certain point where its all about having the best of best and not really about performance anymore. The T7500 is more than sufficient for the majority so if your needs are greater than that. Get it.

 

There is not going to be much of a performance gain, futureproof-ness, heat increase, or battery life decrease. Just a higher cost. Unless you do intense encoding or need the CPU for some reason, just get the cheaper one...

And MrDeeds is right - don't get the CPU just because "oooh it's faster" - I got the T7200 because "ooh it's faster than the T5600!" and I'm semi-regretting it now... I could have lowered my price A LOT and probably wouldn't have even noticed it.

 

Looking at that chart, I think I'm going to cancel my 1502 order (still not scheduled to ship until 8/14 -- ordered 7/7) and wait until September to see how things shape up. I guess I can spend another month or 2 using my HP Pavilion from '01.

Viva La Pentium III 650mhz!

 

I wouldn't necessarily recommend you do that. Theres no way for you to know for sure what an oem is going to do with new cpu releases. They may not offer it immediately after release and they also may not choose to pass the savings on to the consumer immediately. So the september price drop may not translate to real savings to till maybe october or late november.

You just can never really be sure. What would be a good option would be to get the notebook you want with the lowest cpu option and upgrade the cpu later but that also leaves your warranty in limbo.
