The same boards in the 2009 systems will be used in the 2010 systems for cost reasons (Intel designs their chipsets to work with both parts released on an architecture within a Tick Tock cycle so vendors can reduce their costs). This isn't out of pure generosity, but rather saves them time and money, and even makes a product line more attractive as well (i.e. boards can be used with 2 different processor series, as it shares the same socket and chipset).
What this means for the 2010 systems, is there will be NO:
- USB 3.0
- FW 1600
- LightPeak
- SATA 6.0Gb/s
- Additional DIMM slots
So I guess this means for a single processor Hex Core model, the MP will actually have more cores than DIMM slots, 6 vs 4! (actually likewise for the dual Hex Cores 12 vs 8).
The one expansion option I've always taken advantage of in my Macs is adding RAM. The prospect of having just 4 RAM slots in a single proc 2010 Hex core MP is maddening.
The Mac Pro out-expands the iMac in every other category (hard drives, PCIe slots, graphix), except they can't figure out how to get more than 4 DIMM slots in the giant MP tower ... yet they can get the same number squeezed into the tiny space for such things in a 21.5 inch iMac.
Yeah, OK I know it's how they designed the processor boards etc. etc and they won't feel like shelling out the bucks to allow, say, 6 DIMM slots per processor.
But still. Seems lame when a SP Mac Pro can't out-expand an iMac in something so essential as RAM.
Maybe I'm missing something? Can the MP at least handle larger DIMM modules (the tech spec page on Apple's site says 4GB DIMMs are the max for both the iMacs and quad MPs, for a maximum of 4x4 = 16GB each)?
