OPs question here is if it'll use the Intel-Radeon combo module, so it's not so simple as just the CPU generation. Coffee Lake's 'G' version could be much later, and Apple has prioritized graphics over a smaller CPU bump many times (320M instead of gen 1 i series, Iris 650 instead of a bump to the current 8th gen ulv quads, etc).
The 8th gen quad-core chips were not available when Apple released the current MacBook Pro. Also, we're not speaking about a "smaller CPU bump" this time - it's huge! These 65W Kaby Lake G chips don't even offer GPU performance advantages, since AMD offers the GPUs used there separately, and considering the package power draw, I can't imagine that they need much more than a 35W TDP.
There is no mobile Vega with HBM2 outside of this Intel interposer, and dedicated packages also have less compute units than this (and correspondingly ROPs and TMUs). The shared package itself is 18% more efficient and there's no GDDR5, so this chip would still be the most ideal even if mobile Vega exists outside of it, and how it's trading blows with Pascal efficiency for once.
If we could get both the 'G' Package with Coffee Lake Hexacores, all my money would be flying at the screen, don't get me wrong. All I'm saying is that past history would indicate if Apple saw both a GPU advantage and a CPU advantage that could be used, they're leaning GPU as of the last decade.
There is a mobile Vega GPU - AMD showed it during CES. They didn't show any specs, but the chips looks awfully similar to the Vega 20 / 24 units on Kaby Lake G, and due to economic reasons alone I'd expect them to be similar. They probably will come with HBM2 memory too. It doesn't even have to be as efficient - the current MacBook Pro already uses an 80W CPU + GPU combination, they can stay at that.
And I don't think Apple values GPU performance more than CPU performance. Sure, they did use older CPUs in the past to avoid either the Intel GMA chipsets or the need for a dedicated GPU due to the lack of integrated ones. But Apple, in the past six years at least, always used the fastest CPUs available within their thermal limits, and arguably compromised on the GPU compared to a lot of the competition (Radeon Pro 560 vs GTX1060, for example).
I'm sure I've read somewhere the steady state performance settles in around 65W for CPU+GPU on a load for the 15, so the 65W package would already be ideal and would of course use any thermal capacity for turbo. Particularly with 18W within the system saved from power delivery, any bit that uses power = heat.
If indeed they wait for Coffee Lake hexacores, that would be appealing, but I'd still hope it would be in a package like this - why turn their nose up at an 18% shared power efficiency gain as well as the ability to use more space for other things - like more cooling to be able to maintain higher performance longer, like they did by removing the HDD option from the iMac Pro - or a bit more battery capacity which is always nice, or microSD, etc etc. The smaller package still enables a lot of things regardless.
Also, the 15" MacBook Pro can supply up to 89W of sustained power. And even though it can, there aren't many situations outside of synthetic benchmarks which stress both the GPU and the CPU at 100% for a longer period of time, so it should be fine just as it currently is.
Those SDP numbers are not carved in stone.I would have said kabylake G a couple of weeks ago, but having seen the release information 65W is way above the thermal limits for a 13 inch MBP and 100w is way above the TDP for the 15 inch and the lack of a quadcore and hexcore version respectively makes me think it may be unlikely.
Those SDP numbers are not carved in stone.
maybe not but if they down-clock them enough to get within TDP then the performance hit and the lack of quad-core with radeon and hex-core with radeon will put apple off I'm afraid. If I was designing them I would much rather have a quad-core with iris graphics in the 13 inch and a hex-core with a dGPU in the 15 inch, in thin and light pro laptops.
Coffee Lake mobile CPUs are not even announced yet whereas Windows laptops equipped with Kaby Lake G CPUs are starting to appear and will continue doing so in the first half of this year. I think it's inevitable that a MacBook Pro with 4 cores and the Radeon graphics package will appear and I'd say it'll be sooner than later.
I think Apple could be saving the 6 core Coffee Lake MacBook Pros for after they have released a 3rd generation of the present design. A redesign with the Coffee Lake CPUs could arrive early next year - the earliest iteration that could see Apple address keyboard issues and touchbar expense.
[doublepost=1520372575][/doublepost]Two complaints about the MacBook Pro 2016/17 can be addressed with relative ease by Apple with the new combined CPU+GPU.
1. Battery life
2. Price
I would have thought that the 65w Kaby Lake G off the shelf packaged combinations offer significant power savings over a Kaby Lake + AMD Pro graphics solution and thus improving battery life on the same units through lower power draw. The fact that there's an i5-8305G with smaller cache and slightly lower clock speed might also allow Apple to reduce the entry price of the 15" MacBook Pro if they choose to use it.
Indirectly speaking, depending on Apple's plans for the MacBook Pro follow-up they might have been able to engineer better keyboard experience by the time of the third generation if they can make room with a smaller motherboard and battery (smaller battery because of using 65W TDP parts). The 65w parts only do 2.6T Flops whereas the 100w parts (which aren't going into the MacBook Pro have 3.7TFlops)
Where do you have these numbers from? From all benchmarks I've seen, the Kaby Lake G GL is slower than the desktop GTX 1050, which has a floating point performance of 1.8 TFLOPs, or just about the same performance as AMDs Radeon Pro 560 (notebook). Judging by this, a 65W Kaby Lake G would just about equal the current 15" MacBook Pro in both CPU and GPU performance, which is not a desirable thing considering the option of a much faster Vega-based GPU and a six-core CPU.
Battery life and price are also question marks rather than facts. Intel did for whatever reason not specify the price of the Kaby Lake G chips, but their NUCs using these chips are VERY expensive compared to the previous ones, which might make this option not even cheaper than using separate components. Same for the power draw - while it might be lower under load compared to the current 45W CPU + 35W GPU setup, a refreshed CPU + GPU setup would certainly provide more power. And if you actually want to increase battery life while you're at it, just swap the 45W CPU for a 15W one – this would bring down the total CPU + GPU TDP to 50W while offering the same CPU and superior GPU performance compared to Kaby Lake G.
I agree on the fact that mobile coffee lake aren't yet out and apple usually arrives 6 month after it's officially used by every other manufacturer.
And I also don't think apple could justify going from nearly 4Tflops + 4 Cores on a generation, and then 6 cores and less than 4Tflops. Improvements have been made on mobile GPU for sure, but there's no way a 6 core mobile CPU + GPU could be better than the Kaby lake G on power consumption.
Maybe Apple will use it for a new generation of Mac Mini?
Actually it would be very good for them to sell it for 1000$.
