Sun Fire X4450 SPECjbb World Records

Friday May 09, 2008

Dave Dagastine's Blog covers Sun's two new SPECjbb2005 World Records on Sun's X64 systems. The Sun Fire X4450, 4-chip Xeon QC CPUs and Java SE 6 Update 6-P, now hold the 4-chip Multi-JVM World Record and the single-JVM x86 world record. see: http://blogs.sun.com/dagastine/entry/sun_java_on_intel_delivers1

Now one of the things I don't know is if my Sun colleages used a non-standard BIOS on this benchmark. I imagine my colleages did the same thing as the other vendors who benchmark Xeons on SPECjbb, so at least everyone is playing the same field. My personal opinion is that the BIOS should not be tuned differently for different benchmarks. But no one listens to me

Disclosure Statement

SPEC, SPECjbb reg tm of Standard Performance Evaluation Corporation. Sun Fire X4450 results submitted to SPEC. Other results as of 05/6/08 on www.spec.org. Sun Fire X4450 (4 chips, 16 cores, Sun JDK 6u6-p) SPECjbb2005 bops = 464355, SPECjbb2005 bops/JVM = 58044. Sun Fire X4450 (4 chips, 16 cores, Sun JDK 6u6-p) SPECjbb2005 bops = 464355, SPECjbb2005 bops/JVM = 58044. SPECjbb2005 bops = 389208, SPECjbb2005 bops/JVM = 389208.

What a wonderful juxtaposition. In the blog entry previous to this:

http://blogs.sun.com/bmseer/entry/configs_used_for_specpower_ssj we read:

"It is so easy to measure watts on benchmarks that one publishes, Sun does it all of the time."

And in this one, and the one referenced by it what do we see? Well, we don't see any watts :)

... oh, if I were king!

Actually others inside Sun complained bitterly about this. I think we'll see a lot more soon. Maybe you could complaint to HP, IBM, Dell,... they won't listen to me. Maybe they'll listen to you.

Ah - are HP, IBM and Dell bloggers also complaining that SPEC doesn't require power on everything while also claiming to publish power figures for all their benchmarks and then not actually doing so? If so, feel free to point me at those blogs and I'll be happy to comment there as well.

It is much faster than 2x more expensive T5240 ;)
T5240: bops=373405, SPECjbb2005 bops/JVM=23338
X4450: bops=464355, SPECjbb2005 bops/JVM=58044
