Computer architecture, power, and PHP

The Tile-Gx chips have 64-bit processing on their cores, and include floating point math instructions that allow a floating point operating to be done in five cycles instead of hundreds of cycles when done in software.

This is, believe it or not, important for PHP support, Ihab Bishara, director of cloud computing applications at Tilera, tells El Reg.

The Tile-Gx chips might support 64-bit processing, but physical memory addressing on the chips is either 39-bit or 40-bit, which works out to either 512GB or 1TB of maximum main memory. Each core burns less than a half watt of power. From the Register

All that work – to make PHP run faster and use less power.
