This is in direct opposition to the sleek, razor-thin Core M devices that Intel has previously demoed.

There’s no substitute for shipping hardware, and that’s why a great many eyes have turned to Lenovo’s Yoga 3 Pro — the first shipping device with Broadwell inside.

More Intel Core M Coming Q4

by Ian Cutress |
All new CPUs are slated for a Q4 launch, which would mean that they might become available for end users in products on the shelf sometime in Q1 2015.
These initial CPUs should be properly available to the public in Q4 in devices such as the Lenovo Yoga 3 Pro using the Core M-5Y70.
The fact that Chrome runs poorly — markedly worse than Internet Explorer — could be indicative of GPU driver issues, while the 3.5W TDP target Lenovo apparently locked in would explain the throttling behavior.
It’s possible that these weak performance figures and throttling issues are either caused by Intel drivers or by overly aggressive chip positioning.

How's the computer now? Is it still alive fully working? I'm looking forward to buy one, but I'm not sure if it overheats a lot or if a cooling base is needed.
Bought a refurbed laptop with this cpu - hope worth the investment (previous laptop was a lenovo T410 Core i5 520M )
great CPU
