Mac Pro Westmere Performance with PhotoZoom Pro
Here we have an example of outstanding scalability: the run-time is proportional to the number of cores. Very few programs can do so well in using all the available cores.
If only more programs exploited all the CPU cores this well! Even the 2.4GHz model did well here, because all eight of its slower 2.4GHz cores are used. But it’s still slower than the 3.33GHz 6-core.
The 12-core model trounces everything else, with the 8-core 2009 Mac Pro following next, then the hexacore Mac Pro. Cores rule here.
CPU core usage with PhotoZoom Pro 3.1
Outstanding! This is what you’d like to see with every program— full CPU core usage that scales efficiently ( it is possible to use all cores in an inefficient way).
It is a rare and beautiful thing. PhotoZoom Pro scales perfectly—6 cores are 50% faster than 4 cores.
