Modern CPU Flops: Itanic, PowerPC, and Puma

CNet Blog nanotech recently did an article about the 3 most recent CPU design flops by Intel, IBM, and AMD.

For Intel they chose the Itanium, and Itanium 2, there is no doubt that the Itanic as it is commonly called was a failure of epic proportions. It cost to much, and ad NO decent backwards compatibility and no existing code base.  Intel of course still keeps plugging away on it.

For AMD editor Brooke chose the Puma, AMD’s much hyped and highly underperforming CPU/GPU, no argument here, it was and is a dog.

Where I disagree is the selection of the PowerPC by IBM.  While Apple’s use of the PowerPC (all 10 years of it) ultimately ended in failure, the PowerPC did find its niche in many industries.  Servers and supercomputers worldwide use thousands of PowerPC CPU’s.  IBM has created many embedded versions which are used in everything from industrial control to running printers.  IBM has also successfully license the PowerPC architecture to many other companies (over 20 at that, including a couple CPU’s running on Mars). Xilinx makes FPGA’s with multiple integrated PowerPC cores which find there way into about everything. Apple continues to be involved in PowerPC through their purchase of PA Semiconductor.

Perhaps the most well known users of the PowerPC today? The Nintendo Wii and the XBOX 360.
