More Technical Details on QuickSilver Macs

Friday, July 20, 2001

By Senior Editor John H. Farr 

We're giving these to you based on an eWEEK article, not directly from Apple, so bear that in mind in case there's a mistake. What Apple executives explained to Daniel Drew Turner and others at eWEEK is still quite interesting, assuming the writers got it straight.

Here's what we could glean from the above source:

1. The new PowerMacs do have revised logic boards: "The new logic board, which runs at 133MHz, supportsSDRAM but not the newer, faster (and more expensive) DDR standard." The boards are still based on the previous architecture, however.

2. The dual 800MHz processor model does allow for more throughput, despite the limitations of the logic board, because the processors' L3 caches (2MB each) increase efficiciency of data flow.

3. The low-end 733MHz model does not have an L3 cache. And here's where it gets somewhat complicated: "...the new systems also mark a change in Apple's customize-to-order policy: Under the new plan, patrons of Apple's online store can mix and match individual processor configurations." Got that?

4. PCI slot bus throughput rate is almost double that of previous models! Whatever you plug in will run better, in other words.

5. The default video accelerator cards are based on "nVidia Corp.'s GeForce 2 MX chip, a lower-performance version of the GeForce 2." But you can get a GeForce 3-based card for an extra $350. And you can still get a PCI-based Radeon as well.

Comments: That should hold you for a while. The latest PowerMacs still have room for improvement, but who or what doesn't? The point is that they are significantly upgraded, look better, sound better, and are even cheaper in some cases. We think the dual processor model especially would do us nicely, thank you very much!
