Not much for you I’m afraid. L1 size likely to not change significantly to maintain access latencies. Frequencies are not going to increase because of power. Core capabilities will not change I’m any significant ways either. The best bet is more LLC.
- zamadatix 8y agoDon't smaller transistors reduce power consumption?
- gsnedders 8y agoPower leakage is an increasingly large problem nowadays. (Because yes, semiconductors are nowadays suffering from observable quantum effects.)
- choudanu4 8y agoYes, but for the previous few generations of transistor manufacturing, transistors' power consumption has not scaled down as well as their size. This is known as the failure of Dennard Scaling[0]. [0] https://en.wikipedia.org/wiki/Dennard_scaling https://en.wikipedia.org/wiki/Dennard_scaling
- IshKebab 8y agoYeah but power consumption increases with something like the 4th power (heh) of frequency so there's not much you can do even with really low power transistors.
- calvinlh 8y agoAccording to this article on Wikipedia, it's a linear relationship: https://en.wikipedia.org/wiki/CPU_power_dissipation https://en.wikipedia.org/wiki/CPU_power_dissipation Edit: maybe this takes into account that when you increase frequency you might also have to increase the voltage to keep the processor stable, as well? But a 4th power effect seems quite extreme.
- monocasa 8y agoYes, but just like Moore's law is on the edge of being mined out of the easy gains, so is Dennard scaling.
