Nvidia GeForce GT 120 with 512 MB of video memory is the default graphics card, and you can add up to three more video cards. The single-CPU model is available at 2.66 and 2.93 GHz, while the dual-CPU can be obtained at 2.26, 2.66, or 2.93 GHz. With two or four modules installed, it falls back to 2 channel mode, which is less efficient.

For best performance, you should install memory in sets of three matching modules, as the Nehalem CPU can access up to 3 channels of memory at once.
There are two base models, a single-CPU Mac Pro that ships with 3 GB of RAM and supports up to 8 GB, and a dual-CPU Mac Pro that ships with 6 GB of RAM and supports up to 32 GB. For the first time, the least expensive Mac Pro configuration sells for $2,499 – $300 more than the previous entry-level model – which only makes the gap between the $599 base price 2.0 GHz dual-core Mac mini and the 2.66 GHz quad-core Mac Pro that much larger. Nehalem supports hyperthreading, which means each quad-core CPU can work like an 8-core CPU, and Turbo Boost technology allows CPUs to dynamically overclock themselves when circumstances permit – such as letting the 2.93 GHz Mac Pro go as high as 3.33 GHz.Īll that power doesn’t come cheap. Each core has its own 256 KB Level 2 (L2) cache, and each quad-core CPU shares an 8 GB Level 3 (元) cache. It’s been 14 months since Apple introduced the 2008 Mac Pro, and the 2009 Mac Pro is a big step forward: every configuration uses quad-core Intel Xeon Nehalem CPUs for even more power.
