SPEC 2000 results on PowerPC


I've now got SPEC 2000 results for PowerPC.

I'm using a G5 and ran with "-O2 -mcpu=970". My goal is not to demonstrate how fast this machine is, but rather to compare the current mainline with the last release.

The current mainline is, I would say, somewhat better than 3.4.1.

Three tests (176.gcc,187.facerec,189.lucas) work with 3.5, but did not run at all with 3.4.1, so that is clearly an improvement. Two tests (186.crafty and 200.sixtrack) that did work with 3.4.1 no longer work with 3.5 -- that is clearly a degradation. Most of the results are within 5% of the 3.4.1 results (nine better, six worse). The outliers are 252.eon (15% improved), 168.wupwise (10% degraded), 177.mesa (7% improved), and 301.apsi (15% improved).

My current plan is to look into fixing the tests that do not work at all, and then see what's going on with 168.wupwise.
