![]() ![]() The processors also talk to the rest of the Mac Pro more quickly – according to Apple, its memory throughput is more than one-and-a-half times as fast They also benefit from a new set of instructions called SSE4, which can improve everything from video encoding to gaming to database searching. They benefit from a few key improvements.įor example, in addition to their improved 45-nanometer efficiency, their on-chip caches have been boosted to 12MB per each quad-core processor, allowing for near-instantaneous access to a larger amount of frequently used data. ![]() The Harpertown architecture is essentially the same as that of the previous Mac Pro’s Cloverton processors. ![]() But the extra cost may be worth it, depending on your needs.Įach of the two Intel Xeon Harpertown processors available in the 8-core iterations carries four processing cores, hence the 8-core claim. However, to reap the benefit of the storage improvements, it’ll cost you extra for an optional RAID card (£510) and speedy SAS (serial-attached SCSI) drives – £510 for one additional 300GB 15,000rpm drive. The new Mac Pro sports enhancements in all of these areas. Memory must be able to keep up with processors, storage must rapidly fulfil data requests, and expansion slots must swiftly supply displays and drives with pixels and bits. Successful computer design is all about balance. ![]()
