Any leaps in CPU efficiency?

[AyeJayKay]

I'm looking to buy a new laptop and I was wondering if I should save some money and buy a used one or wait till Skylake drops. The reason I'm asking this I is because the transition between ivy bridge to haswell brought huge gains in integrated gpu performance and even bigger gains in battery life.

 

Now I haven't been paying much attention to the mobile CPU space but could anyone tell me if any such gains were made again from haswell to broadwell or broadwell to skylake? Reading the Tech News sub-forum, it seems like Intel is still making gains in iGPUs but have they made similar gains in battery life like they did from ivy bridge to haswell?

Skylake is already out.

 

Skylake is pretty new I would wait until the next line up of CPUs, I would get something with Skylake.

Ummm skylake is here

[kingatlas]

I have a 6700hq and it is working fine it has intel hd530 so go on youtube and see for yourself

skylake is already in laptops

get one with an i5 6xxx or i7 6xxx CPU

Skylake has been out for close to a year. The next big thing is Zen and AM4 APUs

I don't think the MacBooks have been updated to Skylake yet. That is besides the point, I'm asking for efficiency gains not if its already been released or not.

Macbooks aren't exactly up to date with anything. And, we have no crystal balls

yes it's noticeably more energy efficient skylake is 14nm manufacturing process and a new architecture so it's cutting edge technology and as good as it gets.

Mobile chips remain the same. "U" models are still 15W, HQ and MQ remain at 47W when using the iGPU and 37W when using just the CPU

maybe but they are faster.

By a bit - but it all depends on the cooling since most of the speed comes from Turbo - Mobile Turbo is 1-1.2GHz usually

No crystal balls yet the next "big thing" is Zen.

I've read that even though skylake is built on a smaller node, it was even thirstier than haswell/broadwell. Is this misinformation or does that sound about right?

Release-date wise. We have no idea what the efficiency will be like

it's AT LEAST as efficient...i don,t see how and why it couldn't be...i think broadwell is also on the same process node so maybe THAT is as good or better...but haswell hell nahh...

Broadwell is more efficient than Skylake I believe - by a slight bit. The fun part there though, is the L4 cache

Thank you for answering my questions.

but if skylake is faster technicaly it could complete the same task in less cycles which in the end should translate into lower power consumption and longer battery life?

Depends - on laptops currently the fastest CPU is the 5700HQ

[Nena Trinity]

Zen and maybe next lake?

the 5950HQ seem to be faster though....but i assume this must be god awfully expensive!

2.9 base to 3.9 I guess - TDP?
