1. Apparently, Apple still doesn't think there's anything wrong with 4/8 DIMM socket arrangement on computers that are optimized for triple-channel memory. Is it REALLY that hard to squeeze in a 6-DIMM arrangement for single CPU and a 12-DIMM one for dual CPU? Really?
1. Since using multiple channels slows the memory bandwidth, it is huge stretch to label that as optimized. If don't buy 4GB DIMMs from Apple can go above average sizes on RAM.
If optimized has to do with being able to stuff as many 1GB (or perhaps 2GB ) dimms in as possible. That is effectively optimized for older memory tech.
Apple sticking with 1GB DIMMs is surprising. That's definitely a margin booster move. It may be that most folks want to put 3rd party memory in there. However, the 2GB stick prices have to be approaching what 1GB were at this point.
2. 6 DIMMS would involve changing the case to be inch or so wider. There is a tradeoff between being able to easily do the upgrade and also with better utilization of internal space and better aligning the heat sinks with the fans.
There aren't 6 DIMMs slots for similar reason not 6 PCI-e slots. The number of folks up in the demographics probably don't measure very high to Apple.
But where are the NVIDIA cards? I guess we're not getting those after all...
Doesn't have to be Apple that ships them. Although,
FAnd now that we know for a fact that 5770/5780 cards will be shipping, it's only a matter of time before we can flash these puppies.
Folks wonder why there is no Mac video card market.
Ummmm....I guess you could blame ATI on that one. The 5770/5870 are still current cards in their lineup. Their only faster card is the 5970, which probably wouldn't fit in a Mac Pro anyway (seen the size of that thing?).
Unless ATI was writing the drives then could blame them. I've seen reports here that they do the work for Apple. It isn't so much that they are not still toward the top of the current line up, but that they hardware was released to market last year ( September). I can see why ATI would assign their driver teams to finish working on Windows ( and Linux perhaps) before releasing on Mac OS X.
The point was more so that Apple seems to have aligned things so that parts hit the market for long time before do release. That somewhat indicates that their software development is lagging. If had used delay to do something that added value that would be one thing. Seems as though just needed delay to catch up.
Won't be surprising to see the two graphics cards get lapped in 4 months time. Neither will be surprising to see better alternatives to the 3530 and 3565 get lapped too.
