## VBA speed on the Intel-chip Macs: Any faster?

### VBA speed on the Intel-chip Macs: Any faster?

I'm a dedicated Mac and Excel and VBA user.

Right now my current Mac (1-GHz PowerPC) is about 10x slower than the
comparable windows machine for executing VBA macros in Excel.

My question is: Do the new Intel-chip Macs do VBA any faster than the
PowerPCs? (Scaled by processor speed, of course)

Anyone interested in helping me do the comparison by doing the
benchmark below on an Intel-chip Mac?

Here's the results (printed in the immediate window) for a 1-GHz
PowerPC G4 executioning the VBA code at the bottom:

1D: n= 100 Time= 7 -sec
1D: n= 200 Time= 24 -sec
1D: n= 400 Time= 97 -sec

Hoping to hear from some of you,
Jim
