I have seen a lot of people trying to figure out the 3DMark06 performance of Intel's new "Santa Rosa" graphics chip the X3100 chipset.  I had the opportunity to test this on a Dell Latitude D630 (the replacement for the D620) so the results below are as apple-to-apple as you can get.  It is important to note that the machine was running the Dell A01 drivers (only one available since it is so new).  I have read that the current Intel drivers do not support HW T&L, but that the chipset does, so I would expect to see a jump in the numbers when the A02 drivers come out later this year.  If the "jump" is the same as Nvidia got last year, that means the 3DMark06 score will be over 1200; which is not bad.  The test was also run on Vista (32-bit), which to-date has been about 5% in 3DMark06 scores than XP.

Updated: Someone asked for the RAM speed of these machines.  Both the D620 and the D630 used the faster 667MHz memory.

Here are the results:
