Mac Pro (Early 2008)

Eight-core Mac Pro with dual quad-core Xeons. Massive pro workstation performance.

Eight cores. That is the Early 2008 Mac Pro in two words. Intel's Harpertown Xeons put four cores in each of the tower's two sockets at 2.8 to 3.2GHz, where the 2006 machine had managed two per socket, alongside a faster front-side bus, more and quicker RAM, and professional NVIDIA or ATI graphics as options. For the people it was built for the difference was immediate. Editors cutting HD in Final Cut, 3D artists rendering, scientists running simulations and audio engineers stacking plugin tracks all watched their export times fall sharply. The case was unchanged, which nobody minded. Tool-free drive bays, accessible processor trays and generous PCI Express expansion made it a machine IT departments and power users could actually work on. Reviewers rated it among the fastest workstations available at any price, matching or beating Windows and Linux boxes built on the same Xeons. Fully configured it cost well above an equivalent PC workstation. Apple's professional customers were already committed to Final Cut, Logic and Aperture and mostly paid it. Enthusiasts still name this generation as the high point of the cheese-grater era.

Intel Xeon 5400 series (Harpertown)

Intel
Architecture: x86-64, quad-core per socket, dual-socket configuration
Introduced: 2008
Process: 45nm
Transistors: 820 million (per die, dual-die package)

Harpertown brought quad-core dies to Intel's Xeon workstation lineup, and paired two per Mac Pro for a total of eight cores, a huge multiplier in parallel processing throughput over the previous dual-core Woodcrest generation. Built on Intel's mature 45nm process, it offered improved clock speeds and better power efficiency alongside the doubled core count. It comfortably outperformed AMD's competing Opteron workstation chips of the period in most professional benchmarks. Harpertown-based Mac Pros are still remembered fondly by professionals as remarkably capable, long-lived workstations even years after their release.

Reviews & Reception

Received as a decisive, best-in-class workstation upgrade prized for both raw power and its expandable, serviceable design.

Eight cores of Harpertown muscle make this the fastest Mac Apple has ever shipped, and it's not particularly close.

MacWorld
2008
5/5

Rendering and export times drop dramatically compared to last year's model; professionals doing heavy video work should take notice.

Ars Technica
2008
5/5

It's expensive at the high end, but performance-per-dollar against comparable Windows workstations is genuinely competitive.

CNET
2008
4/5

The tool-free expandability remains a highlight in an era of increasingly sealed, non-upgradeable machines.
