This thing is 3 or 4 times faster then my server...

I have a few laptops with that CPU. It is an i7, but it is the slowest i7 I've ever seen.

Considering the i7's you buy, I can see that.

Still, it's Passmark score is huge: 6718.

Is it possible the other components in the laptop just can't get it data fast enough?

In theory, the 2670QM should be faster, according to passmark, then my i7 940. Still,
I don't think it's getting data at 500 MB/sec from two X-25M's, either.

Have you put an SSD in a Lenovo i7 laptop?

Yup, that machine (a Lenovo T410) has a 200GB Vertex2 SE in it. But things that are not particularly disk bound (panorama stitching in Photoshop with 8GB of RAM) seem to take forever.

Most stitching progrmas are quite disk limited. PTGUI creates 80GB of temp files when I work on a large pan for example.

There's not much things except Passmark for which a desktop i7 940 overclocked at 3.11GHz won't be faster than a mobile i7 2670QM operating at stock frequency. Sandybridge CPUs are ~30% faster than the older Core isomething at similar frequency. 2.2GHz*1.3=2.86GHz (less than the 3.11GHz you run the 940 at). Plus, IIRC, the i7 2670QM is a 4 cores/4 threads CPU while the i7 940 is a 4 cores/8 threads CPU. Your desktop still is the fastest computer you have.
