Sure Apple can release a Mac Pro with one CPU as a lower-end addition to the current Mac Pro, but leave the dual-CPU options too.
That's what I wanted them to do since the Intel switch:
- Mac Pro "One" with Conroe, then Yorkfield and now Bloomfield
- Mac Pro "Dual" with 2x Woodcrest, then 2x Harpertown and now 2x Gainestown,
Not just a dual cpu motherboard with just one cpu, but one "entry-level" motherboard with one desktop cpu and one "high-end" motherboard with two workstation/server cpus. And it makes even more sense right now that the price diffrence between "desktop" cpus and DP-server cpus is wider.
Dual-cpu nehalem workstations will be more expensive than harpertown systems at the same clock, due to the higher prices of the cpus (and probably the motherboard, too). So Apple
could release a smaller/more affordable Mac Pro using the Core i7/X58 plateform and then a "regular" Mac Pro with dual Xeons and Tylersburg chipset:
$1499 2.66GHz, Core i7 920, 3GB RAM, 500GB HDD, Superdrive, GPU (Dell's model is $969, Gateway's at $1299...)
$1999 2.93GHz, Core i7 940, 3GB RAM, 500GB HDD, Superdrive, GPU (Dell's model is around $1439...)
$2499 3.20GHz, Core i7 965, 3GB RAM, 500GB HDD, Superdrive, GPU
$2999 dual 2.53GHz Xeon E5540,
6GB RAM, 500GB HDD, Superdrive, GPU (2x$744=$1488 for the cpus)
$3999 dual 2.80GHz Xeon X5560,
6GB RAM, 500GB HDD, Superdrive, GPU (2x$1172=$2344 (+$856) for the cpus)
$4999 dual 3.20GHz Xeon W5580,
6GB RAM, 500GB HDD, Superdrive, GPU (2X$1600=$3200 (+$856) for the cpus)
Apple would probably sell twice as much of each single cpu model as they have ever sold single cpu Mac Pros! And probably with better margins per model. The standard GPU doesn't need to be high-end since not everybody needs one, but there should be some nicer options than what we can have today...
