It's a shame that Apple's innovation doesn't include removable GPU modules - similar to what AlienWare does with the Area 51 laptops.Earlier this year, Apple, after a long wait, updated its pro line of laptops by introducing the MacBook Pro, the Intel-powered equivalent of the PowerBook. Unfortunately, you can't upgrade the graphics processing unit (GPU) as you can with Power Macs.
If you don't have enough, they are forced to use the hard drive as scratch area. Yes, you can add external SATA drives, thanks to the new SATA II Cardbus products.Įxpanding your memory to 2GB can increase performance in two ways:ġ) The more memory you have, the less time is spent transferring to/from the disk based virtual memory.Ģ) Applications like Photoshop and Motion use memory as cache. You can add speed by using external FireWire 800 or SATA drives. Hitachi and Seagate have notebook 7200RPM drives that hold 100GB. You can increase performance by installing a faster hard drive. Your PowerBook spends much of its time reading from and writing to the internal hard drive. There's more to performance than a fast CPU. I don't have any data on whether the faster processor uses up the battery more quickly, but we did measure the temperature at the bottom of the PowerBook before and after the upgrade. We will add those results to this page as soon as we get our hands on a MacBook Pro. Needless to say, we are anxious to compare the new MacBook Pro Core Duo 1.83GHz to our PowerBook G4/1.83GHz. (All three test units had the same Radeon Mobility 9700 with 128MB of video memory.) The Daystar upgrade certainly deserves serious consideration if you wish to extend the life of your current PowerBook rather than buy the new MacBook Pro. Even graphics intensive apps benefit from the CPU upgrade. The Daystar Technology PowerBook 7447A upgrade definitely boosts the CPU crunching power of the PowerBook, as you can see from the graphs above. PB G4/1.5 - Apple PowerBook G4/1.5GHz with 2GB 333MHz DDR memory and Radeon 9700 Mobility 128MB DDR graphics processor. PB G4/1.67 - Apple PowerBook G4/1.67GHz with 2GB 667MHz DDR memory and Radeon 9700 Mobility 128MB DDR graphics processor. Includes 2GB of 333MHz DDR memoryĪnd Radeon 9700 Mobility 128MB DDR graphics processor.
PB G4/1.83 - Apple PowerBook G4/1.5GHz with 1.83GHz 7447A upgrade from Daystar Technology.
