I bought an Asus "zenbook" ux305 for this reason. It uses an Intel core M processor, which idle around 800mHz but turbo boost to around 2gHz, which I believe have been discontinued.
I was worried about performance, but it has been very acceptable. It depends what you need it for, but I can run 2 monitors, a Linux VM and atom all while streaming HD video. Or I can do light web browsing for 10 hours on battery[1]. I love it.
On the rare occasions I need more power, I spin up a spot instance.
[1] If you use Linux on a laptop, install "tlp". It optimizes battery life without a noticeable reduction of performance.
