| 16-05-09 / 17:24 : MacOSX 10.5.7 / Altivec performance regression (cjed) | About 6 months after Leopard's 10.5.6 update fixed a performance regression with Altivec (-50% under xbench between Tiger and 10.5), the new 10.5.7 update makes a step back (the 1,25Ghz G4 obtains a 172 score on Altivec tests against 249 on 10.5.6 and 10.4, and 167 on 10.5). However Floating Point Basic tests (most important after integer test) are up by 10% compared with previous versions of Leopard.
Globally CPU tests are slightly lower than with 10.5.6. The Altivec performance problem could be fixed again in a following update. | | | Comments | | Write a comment | |
