Are the 15" vs 17" CPU's Actually Different? (not speed)

[Stangs55]

Both are listed as Intel Core 2 Duo...but the 15" is offered in 2.53 and 2.8Ghz, while the 17" is in 2.63 and 2.93Ghz.

So are the actually different processors? Or is it just a speed bump?

I think the 17 inch Macbook Pro's CPUs (at least the 2.93) have a 35W TDP as opposed to 25W for the 15 and 13 inch Macbook/Pros. Which could account for the slight increase in thickness in the 17 inch?

Just a different multiplier/core clock, it looks like. FSB and L2 cache is the same, and they are both 45nm Core 2 Duo's obviously.

Well officially, Intel does not offer the 2.53GHz and the 2.8GHz models anymore with 6MB L2. They have been replaced with the 2.66GHz and 2.93GHz models.

The 17" mbp can do the 8gb of ram while the 15" cannot, bummer~ 😡

Do you think this mean that the 15" will be getting the same speed bump in the next few months?

Not to thread hijack but, do you think that this might be addressed at some point (with a firmwear update?) or is this hardwired into the computer?

the 2.53ghz MBP, actually has a TDP of 35w (T9400 CPU). Only the 2.4ghz (P8600) and lower have the "newer" P series chips which have a TDP of 25w.
