CPUs: PowerPC G3

Original article by: Daniel Jansen Arthur, legendary King of England, became the code-name for the third generation PowerPC (PPC) processor, eventually named the 740 and 750. The successor of the 603e, these third-generation CPUs were optimized to run real software, not for some theoretical ideal. Early benchmarks show the 750 outperforming the 604e, making it look like […]

CPUs: PowerPC G4

Original article by: Daniel Jansen First available in the Power Mac G4 in late 1999, the G4 processor is to the G3 as the 604 was to the 603 – and then some! Like the 604, and unlike the G3, G4 is designed for multiprocessor operation. It also runs about 25% faster for basic floating point math […]

CPUs: PowerPC 601

Original article by: Daniel Jansen The biggest change in the Apple product line prior to 2006 was the transition from Motorola 680×0 CPUs to the PowerPC (PPC) family of CPUs. Designed by a consortium of Apple, IBM, and Motorola (a.k.a. the AIM Alliance) and based on IBM’s POWER architecture, PowerPC became the most widely used RISC […]

CPUs: PowerPC 603 and 603e

Original article by: Daniel Jansen The second generation split the PowerPC (PPC) line into entry level 603 and power user 604 chips. The 603 has only 1.6 million transistors, draws about half as much power as the 601, has two smaller caches (8 KB for instructions, 8 KB for data vs. a 32 KB unified […]

CPUs: PowerPC 604 and 604e

Original article by: Daniel Jansen The “power user” second generation PowerPC (PPC) CPU was the 604, unveiled in December 1994 along with the 603. Containing 3.6 million transistors, drawing twice the power of the 601, and with a dual L1 cache (16 KB for instructions, 16 KB for data), this workhorse could deal with four […]

1.4 GHz iMac: What Is Apple Thinking?

We’ve published our first article on the Mid 2014 21.5″ iMac with its 1.4 GHz low-power dual-core i5 CPU, and Chris Carson was not impressed with its value. I want to treat is as fairly and unemotionally as possible, so let’s take a closer look.

Is the Mid 2014 21.5″ iMac a Road Apple?

What happens when you take a MacBook Air’s logic board, a 2012 MacBook Pro’s hard drive, and shove them into an iMac’s case?  You have a modern day Mac Classic without the charm and without the sub-$1,000 price.  You’d also get a lot of people like me asking, Why?
