Anand's i820 benchmarks Bogus?

Thanks to Gene Parrot on the SI thread for summarizing recent AMD760 benchmarks at anandtech.com.
Gene's post is at:

Message 14401800

These benchmarks showed the i820+RDRAM to be a a serious disadvantage to DDR (PC1600) and PC133 SDRAM.
Something seemed a bit odd, however, so I took that trouble to pull up previous Anandtech benchmarks on the i820 from
here:

anandtech.com

and here:

anandtech.com

I also threw in some benchmarks from Tom Pabst, that pro-DDR guy, on the i820 and i840.

tomshardware.com

All tests are on 1GHz platforms.

Some interesting results (see key below).

Very INTERESTING! Looks like Anand took one for the AMD team! Notice that Anand had to use a bunch of
non-standard benchmarks because the one's that he and Tommy usually use--like SpecPerf 3D series, WOULD NOT
RUN on the DDR system.
