Will Haswell provide a *huge* benefit to the 15" rMBP?

[shznit]

I also doubt that Intel will put the fastest GPU with dedicated Memory in just any CPU. So many Haswell won't even be faster. On designs where a dedicated GPU fits I guess they will stick with the slower GPU and only where no dGPU can fit in they will add the best GPU config.

It is unlikely that just any notebook like a 15" rMBP will even get the best possible iGPU. Chances are they get a GT2 or maybe a GT3 but without the on package cache.

If they can fit a quad core Ivy Bridge and 650m why couldn't they fit the GT3 w/L4? If you read the bigger Haswell article he goes on to say that Apple wanted the L4 and a larger gpu in Ivy Bridge but Intel wouldn't do it for just one customer. Why would Apple push for this and then not use it in their flagship computers? I think the 13 and 15 retinas are pretty much guaranteed to get the best Haswell gpu, although I think the 13 will stay dual core.

Well, and in 2014 the next Nvidia Geforce architecture (Maxwell) will offer a HUGE increase in graphics power, which will make the rMBP 15' a much better gaming machine. It goes on and on..
Personally, I'm waiting for Haswell next year.

I doesn't quite work that way but someone already explained. The reason Haswell is significant (hopefully) is smooth UI at retina resolutions without having to switch to discrete, escpecially on the scaled up settings.

Currently from IDF intel will only use GT3 on their mobile cpus, this may change for the budget cpus, i.e. pentium.

Doubtful. Nvidia made huge strides with the Kepler architecture in power efficiency. Since there is no process shrink coming and it will still be a 28nm GPU there is little chances that Nvidia can significantly increase performance while staying in the same power envelope.

AMD faces currently the same problem with their newest desktop architecture. While staying in the same TDP class there just isn't a whole lot of room for improvement without a process shrink.

A huge increase seems very unlikely.

Hmm, to elaborate.. Maxwell *will* be a 20nm GPU, and by looking at the expected roadmaps from Nvidia (which should be taken with a grain of salt), the Maxwell architecture should offer 3x the number of gflops per watt over Kepler. Maxwell was originally scheduled for a release in 2013, but because of problems with the process shrink it has been delayed until 2014 (maybe even late 2014?). Maxwell might or might not be included in the 2014 rMBP, if not then 2015.
Anyway, from my perspective the rMBP should be a mature product by the time the haswell version comes out next year. That's when I'll jump on the retina bandwagon anyway...

And let's not forget 802.11ac, that along with IR-free screens and lower flash prices are enough to make me wait for a year or two. But of course, that decision depends on what you have now.

I currently have an 13" MBA Late 2010. 1.86GHz Core 2 Duo. 4GB RAM.

I am on the fence.

That is cuspy. I had an even older C2D Macbook, and was going to go rMBP-15, but just felt like it couldn't make a satisfactory computer to last for a while w/o 802.11ac and better (read larger and cheaper) flash storage than what is currently available today for outrageous prices. And if I'm going to lay out some semi-serious dough I'll be wanting to keep it for a while because it'll be a MacPro desktop replacement. Those things in addition to lag and IR teething problems convinced me that an rMBP-15 today would just be a bridge to a newer one in 1-2 years time, in which case I felt like I'd lose less money getting a 2011 cMBP-15 at an ultralow price and upgrading it to 16GB / 750GB hybrid. All in I'll be into the temp computer for less than $1000 as opposed to $2300-$2700 for a computer that'll be $1500-$1800 in 1-2 year time.
