Goddamnit, why would Apple want to push the 15" release even further back.
They should put in an Geforce 900-whatever.
What are the benefits of a Polaris GPU?
Are there any benchmarks yet?
If you would look at few last pages, we debunked why there is no GTX9XXM in Macbook Pros.
GTX950M is 55W TDP GPU. Placing it in 85W thermal envelope with 45W quad core CPU would be troublesome. What is more, the GPU that could fit in thermal envelope of MBP is GT940M. And it is on par, EXACTLY on par with integrated GPU from Intel in 15W CPU- Intel HD540.
So no. Other thing than wait for Polaris will be waste of silicon.
Okay thanks, that sounds reasonable.
Is there a big chance that the MBP with the ded. GPU that is available right now will be the last mbp with a ded. gpu?
Is it worth to wait for that update? How are the performance boosts that come with Polaris and Skylake.
Obviously you get TB3, thats on strong reason.
And maybe that redesign with new colors but thats only cosmetics.
What bothers me: are there any issues with that new technology? I think I've heard of some issues of skylake cpus in surface devices?
Buying a MLTJ2D/A now gets you old cpus but they are reliable.
Also you have that benefit of a low price. A new MBP will cost 500$ more than a mbp now
To be honest: nobody knows yet.
Efficiency is the one thing, other is sheer horsepower of the GPU. Most people believe it will have somewhere between FirePro D300 and D500 of performance, some say it will be closer to M395 in performance.
Everything is depending on the core count, architecture, and performance of the shaders in GCN4 arch.
But it is huge leap in efficiency. Raja himself said it is 70/30% leap thanks to process shrink/architecture itself.

I'm hearing dGPU will be an upgrade option and that none of base models will feature dGPU anymore. Also, prices are rumored to be dropped internationally to account for currency changes.
With Iris Pro 580 peak GFLOPs performance at full clock (1150GFLOPS at 1Ghz suggests 1260GFLOPS at 1.1Ghz) essentially on par with the current M370X (around 1300GFLOPS), Apple doesn't have a need to offer dGPUs as anything more than a BTO option anymore.
Mainly power effiency and performance come with Polaris, a quick google search should enlighten you with all the details about it.
Perhaps some skylake chips have been acting up but perhaps consider the following:
1. The processors that go into surface/xps/etc. devices are different CPU's then the ones that will go in the MBP's
2. Apple has the highest build quality, so chips malfunctioning will be very unlikely, as for other brands the build quality and design of the internals is different, and usually a whole lot crappier.
the highest build quality?
I got that kind of mbp where the nvidia chip descended itself from the mainboard under stress.
One way to fix that was to put your mainboard in the oven and heat that thing up.
All I want is a reliable working machine who doesn't get disfunctional after 4 years
Hearing from who?
This doesn't make a lot of sense. Integrated graphics caught up to a GPU based on 4 year old tech, so what? The world doesn't sit still. dGPU is still better than just having integrated graphics. It amazes me that people want Apple to WEAKEN the product.
If Apple wants to ad a lower-priced 15" with no dGPU, fine. But why on earth would anyone want Apple to make the dGPU option more expensive?
Hahaha yeah, except for the dGPU for sure. I don't know why, but Apple can never really nail it regarding dGPU's and internal design. I know several people with dGPU problems.
Hopefully next design won't cause problems
Actually no.
Iris Pro 580 is more powerful in OpenCL than R9 370X.
Simple math: core count of the GPU times 2, divided by core clock.
640 x2 = 1280 x0.8 = 1024.
So Iris Pro HD580 even in Compute will be more powerful than R9 M370X.
Also are the only GPUs currently capable of running OpenCL 2.0, and DirectX 12.1.
That is idiotic... Apple is an American company, with the drop in value of foreign currency apple will have to increase prices in foreign markets in order to recover the same margin.
It makes technical sense. For MBP, power *and* performance matter. Why do you think Apple picked M370X, with a 3 year old core, for the 2015 15" ? There's no better choice within an approximately 35-40W envelope. A fancy 950M or whatever people want on their MBPs will NOT happen unless AMD or NVidia downclock it or generate custom silicon for Apple such that it dissipates only 35-40W . When they do that, you'll get approximately the performance that Iris Pro 580 is capable of.
The MBP is a heavily thermally constrained platform. Just picking some random new dGPU and asking why Apple doesn't put it into their MBP, is a rather tiring question. As an analogy, the MBP has the engine bay size of a Geo Metro, and this amounts to asking why it can't fit in a Dodge Viper engine in there.
AMD Polaris and NVidia Pascal can change this, because they're built on 14nm and 16nm processes respectively. That's a substantial reduction from 40/28nm processes used for a few years now. That will generate both performance gains and TDP reductions.
However, the wildcard here is primarily, does Apple want to stuff that in there ? With Iris Pro 580, they arguably don't *have* to do so, because the 580 is as good or better than M370X, which was not the case with Haswell's Iris Pro 5200 in the last 3 years worth of 15" MBPs. Therefore I would not be surprised if Apple offer only iGPUs in the next MBP and offer DGPUs either as a BTO option or as an eGPU accessory.
I actually hope for Apple to drop the dGPU entirely, as it would make redesigning the rMBP 15'' a whole lot easier: Apple could make the logic board much smaller for all models, thus increase the battery area, and make it thinner and lighter. Also, if the TDP is dropped from 45W+35W dGPU to 45W for all models, thermal design could optimize for a lower TDP in general and would not have to be orientated on a 80W TDP. This could make bottlenecking less of an issue, and allow for a longer battery life.
eGPUs would be a great solution for those who need massive graphics performance, as desktop cards are much faster and cheaper than mobile ones. Also, they could be upgraded at any time, which would ensure a prolonged effective lifetime.
I don't really get why so many people are opposing the Iris Pro 580 so much – the 540 is absurdly fast, the 550 will be even faster, and the 580 will add another 50% performance – which will most likely make it the fastest rMBP GPU to date, and that as an iGPU which uses so much less power.
