There's an article on Slashdot about Intel's relatively new 22 nm |
7 |
SOC (System On Chip) design... |

It's not so much that Atom consumes more power than an ARM SOC, it's |
11 |
that a multi-core Atom, plus a discrete GPU, plus various other discrete |
12 |
components, consumes more power than an ARM SOC. Move the discrete |
13 |
components onto the chip (hence System On Chip), and power consumption |
14 |
goes down. Intel can still wring out a lot of efficiencies. They |
15 |
simply haven't had to in the past. |

That's totally separate from obvious stuff like fabbing only one core |
18 |
on their low-power-chips. A 2 or 4-core Atom on a smartphone/tablet is |
19 |
the computing equivalant of one person commuting to work in |
20 |
rush-hour-crawl traffic in a minivan or SUV powered by a V8 engine. A |
21 |
single-core chip would be equivalant to a 4-cylinder engine. It'll do |
22 |
the same easy job, but consume less energy in the process. |
