interesting indeed, if you read what it says.......
loaded the specjbb2005 results since 1 jan 2007
some interesting stuff indeed.
I added bops/core column, because it tells you about scaling. And hence how much IBM needs to worry. or not.
the power6 at 2 cores does 44045 bops ( 27% faster than the speediest X86, by the way )
the power6 at 8 cores does 43343 bops
the power6 at 16 cores does 43248 bops
pretty much linear performance, indeed.
Now for the shivering......
the closest thing to that power6 is 3 Xeon boxes, 4 cores and 8 cores from Fujitsu ( the same guys that beat up Sun for many years now.... on SPARC ....)
4-way = PRIMERGY BX620 S3, Intel Xeon processor 5160, 3.0 GHz
8-way = PRIMERGY BX620 S3, Intel Xeon processor X5355, 2.66 GHz
16-way = PRIMERGY RX800 S3, Intel Xeon processor 7150N, 3.50 GHz
the xeon at 4 cores does 34587 ( = 100%)
the xeon at 8 cores does 27669 ( = 80%)
the xeon at 16 cores does 21041 ( = 61%)
those power6 chip systems delivers near linear performance, ladies and gentlemen....... the Xeon doesnt, and you can imagine what the numbers of a 32-way Xeon will look like.
Yes we need to worry. About IBM having no competition that can get close.
if you care, you can download a piece of my XLS with the bops/core columns in it. or get it from www.spec.org yourself.
