Hey all
Finally found some good comparative benchmarks for the new low-cost
Itanium. Dell has some SPEC CPU2000 results up for their PowerEdge
3250 servers. They have two servers there, both with identical
configurations except that one has a pair of 1.5GHz Itanium2 chips
with 6MB of cache, and the other has a pair of 1.4GHz Itanium2 chips
with 1.5MB of cache. Long story short, the smaller cache seems to
hurt performance by a large margin:
CINT2000:
1.5GHz/6MB : 1099
1.4GHz/1.5MB : 824
CFP2000:
1.5GHz/6MB : 1875
1.4GHz/1.5MB : 1444
So, while the 1.4GHz chip is only 6.7% slower in terms of clock speed,
it is 25% slower in CINT and 23% slower in CFP. On the other hand, it
still has one of the highest scores in CFP, only other Itaniums and
IBM's Power4 have higher base scores, with HPaq's Alpha 21364 just
squeaking by with a higher peak score.
AMD is just shy of matching the peak score with it's new Athlon64 FX
51, which manages a CFP2000 score of 1329/1423 (base/peak). In CINT,
the Athlon64 FX 51 managed 1376/1447, besting their own Opteron 246
which was the previous fastest CINT processor in the world.
