All that matters here is perf/watt. Laptop part is not able to compete with server part in the same thermal envelope in case of raw compute power.

I have every time said this, and can repeat myself: People believe that 4 TFLOPs Nvidia card is faster than 4 TFLOPs GPU from any other vendor. AMD lost mindshare war few years ago. Now tide is changing. Finally.
Amd used to have reasonable good fp64 performance, now it's a joke ever seems it's faster to emulate fp64 than use its native double precision

People believe that ATI cards get 0 TFLOPs on the huge number of CUDA applications - and they're right.

(And don't bring up one example (or a few) of a cross-compiled app as a counter....)

It will be an Osborne Effect only if Apple goes bankrupt due to delays in upgrading the MP6,1.

Osborne Effect doesn't require the company to go out of business. The definition is about pre-announcing something that craters your sales.

You are right, Aiden. The question is, how much longer proprietary software will bring advantage for Nvidia. Looks like tide has changed lately dramatically.

So far all it looks like they are truly threatened by what AMD is doing lately. And they have to be, cause software is bringing what their hardware lacks. But software can catch up fast. Is this the same case for hardware?

That is why I believe Apple did the right thing with picking AMD. Apple is working on their own Proprietary solution, but one that can work on ANY hardware. Best hardware will always win then. Future however is long. Tide can once again change.

I didn't want to comment but I read on an Hispanic blog about Apple that due the thermal issues with D700 and slow opencl grew Apple reconsidered to include nVidia GPU at least on the 2016 nMP (this is something to take with an grain of salt) also AMD delays maybe pushing back nVidia, I don't don't use either cuda or opencl as to decide on hardware based on its availability but it's undeniably user's cuda preference.

Time will tell. If Nvidia will come with great hardware, I will welcome it on Apple ecosystem again. BTW, GTC starts in few minutes ;).

Mostly true - based on the definition of "crater". If Apple sold zero MP6,1s it would have next to no effect on their sales figures.

Tesla P100 - 5.3 TFLOPs of DP, 10.6 TFLOPs of SP.

Around 5120 CUDA cores with 1035 MHz. Impressive.

600 mm2 O_O.

3584 CUDA cores? That was absolutely unexpected. With 300W of TDP, and HBM2 on 16 nm node?

And I was called as AMD fanboy when pointed that Pascal will not be as power efficient as Maxwell was...

But I can understand that TDP comes from extremely high boost clock. With that core clock, It will be BEAST.

25 times the FP64 performance for 20% more power....

So one Tesla chip is going to cost around USD $3800...? Just made a quick assumption according from DGX-1 $129.000 price.

Update: There's only eight Tesla units in DGX-1.. but that still doesn't tell how many chips are included in one Tesla unit..

nMP Late 2016 with a couple Power CPUs and a couple of Pascal GPUs linked through NVLINK would sound great, but that would cost you an arm and a leg, or both each, and then some :)

Too bad AMD lost the chance to first "announce" a HBM2 GPU. They co-developed the tech, I believe they should have had the need to show it first. Maybe they are still first one out the door...

Maybe Apple will go back to Power, who knows?! Hardly, but...
Said it before, and I understand people like the compatibility, but to me x86 would die already. I know, it's well optimized, over time, but it's still a lot of patches over 30+ year old tech, patched from the get go and along the times, to maintain compatibility with software, that for the same reason also lacked real improvements.
How is it possible that you look inside the Windows folder and still see there files that are decades old?
Maybe now that different architectures get attention, and software is portable between platforms, things will change.
Or not...

Intel/HP owns an much better cpu architecture than arm and powerX, Itanium ia64 but it's semi abandon by Intel and hp barely builds servers on this, Itanium updated with the new tech on Xeon could beat both power and arm.

Mago, I know. Itanium was my hope for the future until it wasn't. I don't expect it to come back though, no one seems to care about it anymore, unfortunately.
I'd love to see Itanium based Xeons, on the latest node, they would rock for sure.
Too bad it didn't survive other interests, it was indeed a much better, future proof, arch.
Maybe it will come back, but MS lost interest, Apple won't port OS X for sure, not just for just for a possible nMP based on it. I guess that would make us both happy :)

And now comes Aiden saying something smart about it...
