2.2GHz quad-core Intel Core i7 vs 2.26GHz Intel Core 2 Duo?

But the cheapest 15" MacBook Pro has a 2.2GHz processor, and my MacBook Pro has a 2.26GHz processor. Does that mean my current MacBook Pro would be faster?

One can't go by Ghz speed anymore as a measure of performance, if you wish to compare actual processor performance, this site is excellent.

If you want to compare video performance, this site is excellent as it's based upon Cinebench for OpenGl which Mac's use.

If your having trouble finding more detail info about your Mac's specs, the free MacTracker will assist.

How much do you think I could get for my MacBook Pro...

this site can help you determine the current value of your machine.

Of course the results might be delayed a bit if a new machine is released or Apple announces a change, (like a processor switch) that will drastically alter the price of current machines. I know that PAIN all too well. 😟

Watching eBay for quite some time is a good clue of what people are willing to pay, compared to what you think your machine is worth from other sources.

I can tell you this though, used machines with SNOW LEOPARD 10.6 installed are worth considerably more than normal because there is a lot of software/hardware drivers that don't exist for 10.7 and people have a heavy investment in Rosetta and older 10.6 based software that they need used/newer machines with 10.6.

So I would boot off the 10.6 disk, use Disk Utility to Erase with Zero the entire drive, then install 10.6 and shutdown the machine, it will stay in the "Welcome" state for the new owner. Let them pay the $29 to install Lion if they wish, but you'll get more potential buyers with 10.6 installed at this time, also you can lower the price a bit as it won't have Lion installed.

Good Luck 🙂

As others have mentioned, the 2.2 GHz i7 quad core processor in the 15" would be much, much faster. As ds store pointed out, the MHz is really not the sole determining factor in performance. The chip architecture, number of cores, and any number of other things come into play. Having established that the i7 will run circles around your Core 2 Duo... if you had two Core 2 Duo machines... one with a 2.2 GHz processor and one with a 2.26, you would never notice the difference. That speed difference is so small as to be virtually non-existent.

Hi.

i think you are a bit confused about processors.

actually there are many things which provide better speed to a processor.

the P4 processor is a 2.73GHz or 3.00 GHz i think but it does not make it faster than a i7 processor which is 2.2-2.5 GHz.

these are just there clock speeds.

it also depends on its lithigraphy which is 32nm for i7 and about 90nm for P4.

also its shared cache.

so obviously i7 is better than C2D because C2D is made with 65nm.

and i have a MBP late 2011 with 2.2 GHz myself. and its very fast.

The i7 CPU is considerably faster than your C2D processor.
