The ‘trash can’ form factor Mac Pro was quickly abandoned after Apple’s hardware ran into thermal constraints and performance limitations. It forced the company to return to the tower chassis that offered Intel’s Xeon processors, and afterwards, completed the transition to the technology giant’s in-house silicon by getting kitted out with the M2 Ultra. However, what forced Apple to get into the workstation category of computers to hold a decisive advantage over the competition? It was its first Mac Pro, which is now 19 years old at this point, and offered some of the most powerful internals at the time. Fast forward to 2025, and you still get some exceptional specifications, but at the cost of limited upgradability.
The first Mac Pro was also the beginning of Apple’s transition from PowerPC to Intel processors, with the machine featuring the same premium unibody aluminum chassis
Intel’s CPUs had shown significantly better‘ performance per watt’ than the PowerPC range, meaning that if Apple wanted to offer the best hardware to customers, it would have to make a switch that others might not be comfortable with, because not everyone is accustomed to change. On August 7, 2006, during Apple’s WWDC keynote, the announcement was made, with the Mac Pro sporting the same design language as the Power Mac M5, but with a revamped interior. As for the brain of the entire system, the Mac Pro was equipped with Intel Xeon 5100-series ‘Woodcrest’ CPUs.
Each chip featured two cores running at 2.60GHz and supported the 64-bit architecture. In total, the Mac Pro could tout a 4-core and 8-thread configuration, which, at the time, offered jaw-dropping multi-core performance, enabling power users to bulldoze through the most demanding of applications. You also got 16GB of DDR2 ECC memory that was populated in eight slots. Each RAM stick operated at a frequency of 667MHz. There were also a ton of expansion options, with users able to add up to four 3.5-inch SATA drive bays, a single 5.25-inch bay that housed Apple’s SuperDrive.
Of course, no workstation can be complete without the inclusion of a GPU, and Apple’s first ever Intel Mac Pro was outfitted with an NVIDIA GeForce 7300 that shipped with 256MB of VRAM, making it a massive surprise for those learning about this fact for the first time. Before you ask, it was easy to swap out the existing graphics card for a more capable one. There was a ton of I/O to allow for the expansion of a multitude of peripherals. As for how the Mac Pro got its ‘cheese grater’ moniker, the front side of the case featured perforated holes, a design aspect that is still adopted today in the newer chassis and is a major step-up from the Power Mac G5, which was much noisier.
Looking at how efficient Apple Silicon is, a tower case like the Mac Pro seems overkill to house these components, and since each unit is costly to make since it requires precise milling and increased raw material, the M3 Ultra is currently exclusive to the Mac Studio. Whether or not Apple will continue to update the Mac Pro is anyone’s guess, but even if it no longer has a place in the Cupertino firm’s lineup, it will always have a place in people’s hearts.
