Waiting for Skylake MBP thread

[snc]

Probably you didn't research well, though.
There can't be a GPU more powerful than a GTX950M because of its power consumption and consequently thermal dissipation.

There are only few suitable options:
- a good enough iGPU which outperform the current MBP dGPU
- customized GPU chips with low TDP
- waiting for Pascal/Polaris with low TDP and great performance
- Apple stop making its notebooks slimmer ...and getting instead thicker.

So, pick up your favourite reason.

960m aka 860m has simillar tdp as 950m becausr is the same card just with ddr5, and I dont get the tdp limitation if on web browsing etc. discrete graphic can be in idle mode

GTX 950M, 850M, 860M and 960M - all of them use the same core: GM107. It is the same as desktop GTX 750 Ti die. It has 60W TDP. Power Supply of Macbook Pro 15 has 85W. How do you think you would be able to power at the same time 45W CPU and 55W GPU? What about the chipset which uses 6W? What about the screen, the board, RAM, Hard drive? All of this consumes power.

There is absolutely no benefit for thermal constrained environment to use discreet GPUs especially if they are not much faster than integrated.

as koyoot say, the TDP of the GTX9**M is about 50W and beyond.
MBP is not capable of power them.
And yes, dGPU can be use in idle mode, but when you start gaming/working in something harder, you'll get a nice 2000$ aluminium cooking panel

 

[koyoot]

No, it would not be a cooking panel, but just Power throttling would occur and you would end up with MUCH slower GPU. That is all what could have happened. Would in that environment GTX950M be faster than HD580? I don't think so.

 

[girgostz]

I think the thread has been changed to "waiting for the new dGPU",
Well,.. am I on a gamers forum ?
Why not making a new thread about graphics ?

What about the new chips and launch of new RMBP.
Do we know which chip 13 rmbp will have ?

Irid 580 will be much slower than 960m and dell xps 15 has 960m dont know why macook pro 15 cant

 

[Serban]

anyone seems if Apple will put a dGPU to be Polaris. but anyone can post a link with polaris specs or something

hmm i didn;t know that dell xps 15 has 960M inside, so yes a fair question, why Apple can't put 950M or 960M inside?

Dell XPS 15 has GTX 960M because it is powered up by 130W PSU. Also, look at the temperatures on the surface of the computer in the stress. They are way too high.

Mbp isnt about gaming, so if ur looking for a good card then go buy a dell

Can't see any throtling and laptop is capable to run games on high
Edit: there are throttling scenarios but in real game scenarios laptop run well

Yes, but why they chose overprice cpu with iris pro edram ?

 

[Krubbadoo]

totally agree with you Girgostz! A lot of people neither need nor care about dGPU extravaganza. This should be in another thread in my humble opinion.[/QUOTE]

Have you read the review itself?

The i5-6300HQ quickly throttles from its 2.8 GHz (@Cinebench tests) in steps to 1.8, then 1.4 and finally 800 MHz. The temperature of the 6300HQ drops from 95 °C (limit where the throttling sets in) to 70 °C at the same time, just to rise back to 90 °C as soon as the CPU continues to run at 1.8 GHz.

The GPU is also affected by these temperatures. Maybe the linking of the CPU and GPU heat with dual-heatpipes was not a good idea after all. A warm processor will also warm up the graphics card. The GTX 960M therefore also throttles its clock. We can see 650 MHz in the stress test with fluctuations to 1,200 MHz, but it runs at 650 MHz most of the time

Throttling everywhere then? No, as we described in the section "Performance," the i5-6300HQ can maintain 2.8 GHz, but only if you don't stress the GTX 960M at the same time.

You might be disappointed if you expected high-end performance from the XPS 15 at any time and in every situation. The XPS 15 not only reduces the CPU clock to 1.6 GHz on battery power, but it also acts sluggish, which will certainly not please power users. It is annoying when the system does not recognize that you attached the PSU over multiple CPU benchmarks and that it should run at 2.8 GHz, because you will lose time. This is also one of the reasons that we deduct one point from the overall rating. Unfortunately, the i5-6300HQ cannot utilize its full performance on mains either, at least in single-thread scenarios.

Yeah, it throtles in not real scenarios like prime of furmark, tests in games shows its capable to handle games on high with full hd - unreal for iris pro 580

GPUs aren't only used for gaming.

 

[koyoot]

Are you able to use all power of a laptop while using it without the plug? Is it able to handle any task without the plug? How it behaves without the plug?

All you want is gaming machine, I suppose, not a laptop. Laptop is mobile, that you can use it constantly without the need to plug it to the wall, to get 100% of it.

With XPS, not only you have much more robust PSU compared to MBP, but without it it will declock the CPU. How usable is that?

How sure about that you are?

Dell is 130W, rMBP is 85W.

100% sure I don't need gaming machine or even gaming laptop because if I want to I could buy 1000$ laptop with 960m that anihilate iris 580 in games. I just think they should chose i7-6700HQ or i7-6820HK and update macbook pro 15 (still on haswell) months ago.

 

[koyoot]

So far in table of contents of gaming benchmarks on notebookcheck Dell XPS 15, the particular model, scores the lowest of the lot of computers equipped with that GPU. The differences are not big, but are meaningful in average framerate.

I am not saying it will be slower. The problem for GTX950 and 960M is that in thermal Envelope of Macbook Pro and 85W it will be MUCH slower due to power throttling. How much? I suppose it would not be able to maintain even 50% of nominal TDP.

So picture now this. HD580 gets graphical benchmarks on GTX950M levels which is around 25% slower than GTX960M. What would you pick? 3 FPS more in FullHD, on average, or reliable computer?

 

[snc]

I checked notebookcheck and960m is sometimes 1.4x of 950m on high details, thats huge differwnce, hard to compare

 

[koyoot]

Again, I ask you, how will 55W GPU behave in 25W thermal environment?

 

[j1104638]

Sorry but you're wrong.
There are no miracles. Physics will take what you owe it.

1000$ laptop with decent CPU (not necessary the top one as in rMBP) and 960m will be noisier and/or bigger and/or throttle more. And with such differences your comparison becomes falsification.

Dell show that can provide 960m without throtling in games ofcourse it use more W but its still very thin laptop.

There are 1000 dilars laptop with 960m and they dont throthle in games but yes they are much bigger

It cannot provide even though it uses a lot more W and is not as thin as rMBP. Benchmarks above have proven this.

I am sorry, but you are missing completely the point. MBP power supply is 85W. Dell XPS 15 to power all of his components needs 130W PSU. That is 45W more than MBP.
