About a month after the launch, the first comparative tests on the new PowerBook 667 and 800 MHz begin to appear on the Internet and the results say that it really seems that Apple's promises on the staggering speed of the machine have not been met in the air. In particular, the move to entrust the graphics section to the Radeon 7500 seems to be winning.
Preliminary tests carried out by Barefeats, for example, show that the PowerBook 800 in tasks that require intensive use of the GPU is in fact equivalent to a dual processor G4. In this case, obviously, the greater power of the CPU that has two G4 chips is amortized by the laptop thanks to the graphics card. Only in Photoshop actions does the Dual Processor manage to stay significantly in front of the laptop, but certainly not twice as much as one might think.
The Titanium, in turn, literally sweeps away a PowerMac G4 667 MHz equipped with the old GeForce 2MX card.
Tests that are also confirmed by some tests, also these preliminary but unequivocal, carried out by xlr8yourmac.
The site compares a Titanium 800 with an old Titanium 667 which is much slower: from 40 to 100% in Quake and between 23 and 25% in other applications that require intensive use of the graphics card, such as Cinebench and raytracing.
Note also the tests that Xlr8YourMac always carries out by comparing a 700 MHz iMac with a 667 MHz Titanium. The Quake desktop loses across the board, despite the faster CPU. A new demonstration that the Titanium graphics card really can offer high-level performance by transforming the laptop into a professional station even for those who use the Mac for creativity and DTP.
