Storage cost has fallen even faster than MIPS cost; even so, Free the MIPS! has some good comparisons for processors. Intel's Core Due (in my MacBook) claims 20,000 MIPS. In 1977 the Cray-1 supercomputer held the record with 150 MIPS.
The Cray-1 would not have liked rendering an 8 megapixel RAW file.
PS. A comment on the GMSV post references this 1989 internal research paper on why perceived performance was not matching CPU improvements. It's a great reference, the article reads sadly well today.
