Haswell Prediction Poll: Sept? dGPU?

Will the Haswell rMBP be announced in September with a dGPU option?

  • Total voters

  • Poll closed .
The 2013 base 21.5 iMac now comes with Iris Pro graphics. The previous had the 640M. This means Apple thinks that an Iris Pro can replace a 640M, but not a 650M.

Since the retina's came with OC'd 650Ms, I am now doubtful will only see Iris Pro in the 15".

The new iMacs do make a statement however, that the Integrated GPUs are catching up to the mid-range dGPUs pretty fast.
 
Iris Pro only on the 13"

HD 4600 with 760M on 15"

In case anyone is wondering, the quad core performance parts for the 15" has the 4600 not 5200.

i would be devastated if there is no 15" option with Isis Pro.

i personally do not need a dgpu in my usecase (programming, adobe suite), and i actually do not want a dgpu because it still uses power (when sleeping mode) when the igpu is being used. - im fine with them having two options for the 15": an iris pro, and 4600+dgpu for all you graphics hungry people

i also think that a HD 4600 + 7XXM is feasible for the imacs due to their lower resolution, however the current gen retina's have many problems with the igpu not being able to cope with the resolution (web browser scrolling framerate problems) - so i dont expect to see a HD 4000 series in the refresh
 
Would they make 2 seperate cases, one for the base iris pro 15" (no gpu) and one for the dgpu version?

not using a dgpu could save a lot of room. Any other examples of apple doing this (on the same model)?

There are 28W dual core parts with Iris 5100, and 'quad core performance' i7 parts with Iris Pro 5200.

The 13" isn't going to get Iris Pro because that would mean moving up to a full 47W quad core i7 like the 15" uses. They could probably handle the thermal load but it would result in lower battery life when the clear trend right now is longer battery life.

Completely wrong.

My guess is they put Iris Pro in the cMBP, and yes, that means they'd refresh that line again. I expect 5100 in 13". If they really care about the 13", they can do the "Iris Pro" of Broadwell for the 13" next year.

do some googling and you will see how much of a pia it is for linux + rmbp. it is super hard to get a working solution of graphics card switching. so you either have to pick the igpu with weak performance but great battery, or use the nvidia only and get performance but kill your battery

anandtech has a good section of the 7XXM cards in the imac:

I see what you did there

There are a lot of people here saying Apple doesn't care about pros or gamers etc.

There is just one other thing Apple cares for less than that... it's people running linux on their machines.

Ah yes but nothing specific about the GTX 760M. Did you have any thoughts about it being in the next rMBP?

its considerably faster than the 750m however the power usage might go over the TDP:
GeForce GTX 760M 768pipelines at 657MHz = 50-55Watt
GeForce GT 755M 384pipelines at 980MHz = 45-50Watt
GeForce GT 750M 384pipelies at 967MHz = 35-40Watt
GeForce GT 650M 384pipleines at 735-900MHz (rmbp uses the 900 version) = 45-50Watt

True. And seeing as how they've never used a chip in the mbp that's not in an iMac, I suppose a 760M is very unlikely for that reason alone.

Unfortunately they're not going to put that in there. the 760M is a clocked down 770M, which is a massive chip. They would be much better off putting a clocked up 750M (755M), versus a 760M.
 
But a 760M chip running at lower clocks is more power efficient than a 755M. While that doesn't matter in a desktop and the <=755M chips are cheaper on an expensive notebook a 760M is worth a consideration. I think it is unlikely too but if I was the guy who decides it, I would say either a 2GB 760M or no dGPU at all.
 
The real question is what Apple is going to focus on. Battery life or GPU performance? Yes, a dGPU that turns off and on could offer a solution, but how much of a difference will it really make in terms of real world applications? One thing is for sure, the rMBP 13 is going to be the biggest winner in this year's refresh.
 
670mx/675mx/760m/765m/770m they all have the same gk106 core

however their differences are in the clocks and the bus width, the 760m and 765m have a 128 bus, the 670mx and the 770m have 192, the 675mx has 256

simply put, gk106 isn't going to happen. thats very unfortunate, but they receive a very large discount if they buy the same parts for the most common pcs that they have, i.e. its either the 750m or 755m

basically, no performance gains whatsoever. it might actually be worse, given that the cooling doesn't handle that well the heat, with cripple boost 2.0 they might even perform worse.
