But there are plenty of SODIMM-sized ARM embedded modules with much more compute power than the Pi already.

And they are also probably a lot more expensive than $30.

I wouldn't say a lot.

How do they rate against Videocore IV? AFAIK, ARM core represents only about 2-5% of total computing power in RPi. And can you provide some links, please?

"Total computing power" is massively load-dependent. And I don't think The VideoCore IV is massively outstanding in the field of embedded GPUs.

Links? This is turning into a let-me-google-that-for-you, but they appear very regularly on http://linuxgizmos.com

I see it more like a SIMD processor than a GPU. It's not massively outstanding, but there's a lot of value of it having an open documentation, a known instruction set.
