10.4.10 CD: 49MB C2D: 74MB Why?

Anyone care to speculate why the CD downloads are 49MB while the C2D downloads are 74MB? Only difference to my knowledge is i64 instructions.

There could be a firmware update included for c2d and not cd?

Then again I have a CD MBP and the update says it's 74.1Mb

Ok. That's possible. A lot of firmware there.

I am predicting the C2D update is bigger because of 64-bit stuff of the Core 2 Duo processor and some optimization for the Core 2 Duo processor.

In the main thread some CD users where reporting 49MB. I wonder if it could be because of installed apps.

2.33GHz MBP here with a the 49MB download here.

Must be something to do with previously installed software then.
