Featured Mac Pros
The first generation Intel-based Mac Pro “Quad Core” (MA356LL/A) features two 2.66GHz dual core Intel Xeon 5150 processors that share 4MB of level 2 cache per processor, a 128-bit SSE3 vector engine, and 1.33GHz 64-bit dual independent frontside buses. Apple also offers a custom configuration with two 2GHz Dual Core Xeon 5130, two 3GHz Dual Core Xeon 5160, or two 3GHz Quad Core Xeon X5365 processors.
The 2.66GHz Mac Pro come standard with 1GB of 667 MHz DDR2 ECC “fully-buffered” RAM with a heatsink design different from generic FB-DIMMs. This is upgradable to 16GB maximum RAM. They come standard a 250GB (7200RPM) 3Gb/s Serial ATA hard drive and a dual-layer 16X Superdrive and a NVIDIA GeForce 7300 GT video processor the had 256MB of VRAM that supports one dual link DVI port and one single-link DVI port.
The Mac Pro offers a number additional expansion options than its predecessor, the G5 PowerMac. One of the first noticeable options is a second 5.25” optical bay, followed by four 3.5” direct attach hard drive bays. Four PCIe slots, dual Gigabit Ethernet, five USB 2.0 ports, two Firewire 400, two Firewire 800 ports, optical audio in/out, etc are also standard. AirPort Extreme 802.11g/n, Bluetooth 2.0 and a modem are optional expansions. The Airport Extreme and Bluetooth are no longer available from Apple, so USB wifi and Bluetooth adapters can be purchased.
Mac Pro Early 2008
The early 2008 Mac Pro Eight Core (MA970LL/A) is powered by two 2.8GHz Quad Core Intel Xeon E5462 processors with 12MB of level 2 cache per processor, a 128-bit SSE4 SIMD vector engine and 1.6GHz 64-bit dual independent frontside busses. The Eight Core 2.8GHz processor utilizes a more advanced architecture that makes this processor faster and more efficient with larger level 2 caches and faster frontside busses, more memory, and support of faster SCSI drives. Apple also offers a custom configuration of a single 2.8GHz Quad Core Xeon, two 3GHz Quad Core Xeon, or two 3.2 GHz Quad Core Xeon processors.
The 2.8GHz Mac Pro come standard with 2GB of 800 MHz DDR2 EEC fully-buffered RAM (max 32GB). It also features a 320GB (7200RPM) with 8MB cache 3Bg/s Serial ATA hard drive. The optical drive remained the same as the original release, but graphics processor was upgraded to an ATI Radeon HD 2600 XT card with 256MB of GDDR3 VRAM
Mac Pro Early 2009
Before Intel even announced the Nehalem processors, Apple began offering this processor in their Mac Pro. The early 2009 Mac Pro Quad Core (MB871LL/A) is powered by one 2.66GHz (MB871LL/A) Quad Core Xeon W3520 Nehalem processor or two 2.26GHZ Quad Core Nehalem processors with 256k of dedicated level 2 cache per core, and 8MB of fully shared level 3 cache. The new 64-bit Nehalem architecture is substantially faster than previous processors and supports Hyper-Threading which allows two threads to run simultaneously on each core. Turbo Boost also automatically boosts the processor speed based upon its workload. The frontside bus has also been replaced with a QuickPath Interconnect (QPI) system that allows fast access to the I/O, disk, and other Mac Pro subsystems.
The 2.66 Quad Core comes standard with 3GB of 1066 MHz DDR3 SDRAM, upgradable to 16GB and 2.26 Eight Core has 6GB upgradable to 32GB. Also standard on both models is a 640GB (7200RPM) 16MB cache 3Gb/s Serial ATA hard drive and an 18X dual-layer SuperDrive. The Quad Core’s graphics processor is a NVIDIA GeForce GT 120 with 512 MB of GDDR3 VRAM. Other changes consist of four PCIe 2.0 slots, four Firewire 800 ports and a reengineered interior with memory and processors on an easy to remove tray.
