Yes, it's integrated, but the site shows it to have 128MB dedicated memory rather than shared.
I've never known an integrated yet to have VRAM of its own; that's kind of the point of it being integrated. (Sidenote: Some laptop graphics are very funky exceptions to this rule, as they try to use the turbocache option. It's weird.) I especially doubt that the 7100 does so. It's probably just your run of the mill non-geek typo.
This is about the best stock information you can find.
If you look here and scroll down quite a bit, you can see specs for the 7025/7050, which are nearly identical to the 7100 except the 7100 apparently increased core speed somewhat (in particular, the 7 series integrated seems to have gained a slight boost on Intel boards) as well as HDMI capability/compatibility.
So while the numbers on the 7100 will be somewhat higher than the ~850 MT/s reported on the 7025/7050, your X1950pro for instance (for convenience 
) pulls 6900 GT/s-note the G rather than the M; this means your card has ~8118x the raw power for that given metric.
Granted, there are other factors to consider, and you're not ever going to be seeing those kinds of numbers. But you might try referencing Tom's for your comparisons, although you may have to look back a quarter or three to find the 7100 at this point (and do note that if the 7100GS, which is the dedicated card, is reported, it will probably be worse than the integrated 7100).
The bottom line is that while integrated has come a long way, it's still a step above, quite literally, nothing. (That's the next step down.) So the question again arises just what exactly are the needs to be filled.
