If you are talking about 'just spec benchmarks' then yes I could see IBM being able to do this.
The GPUL could bench out better in the SPEC test since this new CPU is a single core chip (I was kinda surprised about that). In real world usage a DUAL or QUAD core Power4 would KILL this chip.
[ everyone should know that all the standard quoted SPEC numbers are for SINGLE CORE versions of the Power4 (not the dual or quads) so when someone says 'the intel/amd are close to beating the power4 you can feel free to throw that back in their face'
I'm not sure I have this totally right but....
IBM started the Power4 as a DUAL CORE cpu and then as the process went on they found a way to make use of 'bad' two core chips. When the 'bad' part of the CPU was only affecting a single core IBM started to market single core versions of the Power4.
One would hope that as IBM had more time to look at the building process they should have been able to produce more 'good' (dual or quad core) CPUs and less and less single core (bad) chips.
If IBM is at that stage where they don't really have all that many 'bad' (single core) CPUs comming off the line they need to do one of two things.
CRIPPLE a GOOD dual core CPU. (not too smart)
Have something else to use IN PLACE OF a single core Power4.
Now they have that 'something else' in the form of the GPUL. Faster than a 'single core' power4 but still keeps the dual-quad core Power4s on the top of the list for big iron power servers.
This is just me thinking aloud so take it for what it's worth but it seems to make sense.
