(Q) Mobile Haswell Iris vs Broadwell Iris

[bergami]

I intend to buy an ultrabook for ultra mobile to work, to study and perhaps games.

With Haswell Iris 5200 it will be a remarkable achievement to get the highest battery life plus a good gaming device, reaching close to an GT 640M.

But Haswell Iris is a "tick", so it is not perfectly improved yet, with a year of feedbacks intel may release something perfect at Broadwell "tock" reaching something close to an GT 750M maybe? But my overall question is:

Should I get an ultrabook this year (haswell) or next year (broadwell)? (I have no windows mobile devince for while)

Thank you.

The real question is do you need the new device now? It always be behooves you wait with technology.

Will Broadwell be better? Sure. But it's also a year out.

IMHO here, but you may just as well get Haswell now. If you wait a year for Broadwell, then you could just as well wait another year for Skylake, etc. Waiting a month or two for a new product is one thing, but if you're talking about waiting for whole generations then you either don't really need/want the product, or you may be expecting a bit too much in the next generation.

New products will always be better. So at some point the cost of waiting is more expensive (opportunity cost) then just using a new product now.

I need one, I am sick of my android tablet...

you should definitely buy now, broadwell is a year and a half away

The 5200 isn't going into many Ultrabooks, it is only available on 47w TDP MQ parts. There are a few 28w parts that get 5100 but don't expect to play newer games at 1080p on any Intel integrated chip even the 5200.

There's a pretty substantial trade off between performance and weight and we aren't to the point where you can pack decent gaming performance into an ultrabook even if you're willing to spend a lot of money. Maybe if Skylake implements DDR4, but that's to far into the future to be worth speculating about.

If you absolutely need a thin form factor then you sacrifice gaming performance. If you need mobile and gaming get a thicker laptop.

I don't think ULV Broadwell will be able to get close to that performance level.
Just compare this to that, current ulv chips are quite a lot slower than HD5200, let alone a GT650m/GT750m. They'd have to more than double their perf. per Watt to get there with Broadwell, that's stretching it imho.

edit: saw that ulv hd5000 will probably add a bit on top of that performance. Still doubt broadwell @ 15W and GT750m level will happen.

Sandy Bridge was GPU generation 6.
Ivy Bridge 7.
Haswell 7+.

And Broadwell will be a new GPU uarch with generation 8.

720p is just fine, although I'd like to play newer games and don't lose my mobility or baterry life

It depends on what you need. If you need a laptop at all, I'd recommend looking into a Haswell/Iris Ultrabook as they should be pretty awesome and have good battery life.
