Moore's law is over. Pentium 4s reached 3GHZ 15 years ago. CPUs try things like parallelizing while the human brain thinks sequentially. CPUs are still getting faster but at an incrementally slower rate. A 4 year old Macbook Air is half as performant as the latest. In previous decades, the performance gains were 2-5X per year.
A paradigm shift (quantum computing?) needs to happen soon so computation can continue scaling.
- nemothekid 12y agoMoore's law was never about performance.
- billions 12y agoMoore's law is about the number of transistors on a chip which is reaching a limit because heat cannot be dissipated fast enough. Heat is the primary limit on performance.
- sliverstorm 12y agoMore transistors is still better, even if they need to be off most of the time. You can spend more silicon on advanced features, just like AVX, spending transistor count for performance at neutral power cost.

- DigitalJack 12y ago"In previous decades, the performance gains were 2-5X per year." What decade was that? According to this[1], it's never been better than ~50% year over year.
