Photoshop will run a lot faster (with the G5 plugin) on the Dual 2.0 than it did on the Dual 1.42. Like, twice as fast. And yes, it will also easily beat the Xeon.
The same will be true of many other apps when they are recompiled for the G5.
Once again, the XBench numbers are worthless. Ignore them. I would also not worry too much about the Cinebench numbers until the app has been recompiled for the G5 (though I don't know how soon that will happen since apparently Maxon uses CodeWarrior, not GCC). The fact that it is beating the G4 by 10 to 20 percent per clock cycle in Cinebench is actually pretty impressive given that the code is compiled with the MPC 7450 as the target processor. Other apps will show much bigger gains, especially when they have been recompiled for the G5.
Everyone seems to be forgetting how the MPC 7450 was considered a dud at its release because it was performing 20% slower than the MPC 7400 core, clock for clock (see, for example,
http://www.xlr8yourmac.com/G4ZONE/G4_733mhz_review/apple_G4_733_tests.html OR
http://www.barefeats.com/G4733.htm). But today the 7450 core matches the 7400 core clock for clock (the 7400 is no longer produced, but it is literally the same core as the G3 750FX, so you can compare the iBook 900 to the PB 12" 867 on non-Altivec tasks to see what I am saying). We are also forgetting how the 1.5 Ghz Pentium 4 was considered an abject failure on release day because it could barely keep up with a 1 Ghz Athlon, but today the 3 Ghz P4 will spank a 2 Ghz Athlon (1.5/1 is the same ratio as 3/2, if that isn't clear).
Actually, you REALLY ought to take a look at the second link (
http://www.barefeats.com/G4733.htm)! The Cinebench (Cinema 4D) benchmark in it "proves" that the new 733 Mhz G4 is actually SLOWER than the 533 Mhz G4 it replaced! Yes, that's right, the single G4/533 ran the test in 44 seconds vs. the single G4/733 time of 47 seconds. In other words, before Cinema 4D was recompiled for the MPC 7450, it actually ran 33% SLOWER clock for clock on the MPC 7450 than it did on the MPC 7400. But today, with Cinebench recompiled for the MPC 7450, it runs at the same speed clock for clock on an MPC 7450 and an MPC 7400 (in other words, there was a speed gain of almost 50% from recompiling for the 7450). So, like I said, it is really impressive that the non-recompiled Cinebench app is running 10-20% FASTER clock for clock on the G5 versus the G4.
The moral of the story is DON'T judge a new processor before the before binaries have been recompiled for it.
