The Verge had this to report:
It’s been two years since Apple’s Mac Pro has received an update, but today’s the day: as rumored, the 40-pound desktop, lovingly known as the “cheese grater,” will be updated with fresher components than the pair of 6-core, 2.93GHz Intel Xeon X5670 processors it’s been kicking around since 2010. Unfortunately, it’s not much of an upgrade: you can simply get a pair of six-core 3.06GHz Intel Xeon X5675 processors rather than the 2.93GHz ones we just mentioned. The base model will start at $2,499 for a single quad-core Intel Xeon W3565 processor at 3.2GHz, with an optional upgrade to a six-core chip, or you can spend $3,799 to get a dual-processor configuration with a pair of the Westmere-EP based 2.4GHz E5645 chips, and upgrade to the aforementioned X5675 for an unspecified amount.
Everything else stays the same, it seems: you can get up to 64GB of RAM, 2TB worth of solid state drives (but only running over SATA 3Gb/s), AMD Radeon HD 5770 and 5870 graphics cards (which we thought were out of production), 802.11n networking, Bluetooth 2.1, Gigabit Ethernet, optical digital audio in and out, a combo DVD writer, and a host of FireWire 800 and USB 2.0 ports (no USB 3.0 or Thunderbolt). It’s probably still a powerful machine, but if you were hoping Apple’s workstation would see the latest and greatest technologies, we’re afraid you’re out of luck for now.
If you visit the Apple store, you’ll notice the “new” tag next to the Mac Pro. The question remains, where does this leave the future of the Mac Pro? This update obviously means it’s going to be a while before we see a completely re-designed Mac Pro.
