[Rumor] GTX1080m is going to out - perform Titan X.

Its really not that simple..... at all. 8 cores would be very hot/power hungry on a laptop, it can work(P570WM) but it would require something huge like the P570WM.
No one would make a specific CPU for just one laptop....

Anyways, on topic:

GTX 1080m be quite good but I think what comes afterward will be way more interesting to current 980 DE owners/980m SLI owners.

I dont think just 30-35% performance is worth the upgrade cost.

 

It's more to do with the fact that most laptop/PC workloads are not suited to high core counts.

Intel already does high-core, low-power CPUs such as the Atom 2758 (8-core, 16 thread @ 20W TDP) or the new Xeon D 1570 series (16-core, 32 thread @ 45-65W TDP). These generate very little heat. The Atom boards often don't even have active cooling and rely entirely on 40mm case fans (since they're targetted at mini-ITX 1U servers).

 

I meant full 8 cores with comparable IPC with similar quad core processors if it makes any sense.

 

They are full 8+ core CPUs. I've got 2 of those 8-core atom boards running 1U core routers and some other bits and pieces. They're awesome. Similarly, the Xeon D series will outrun the regular Xeon E3 series under properly multithreaded apps.

They even have the PCH integrated (basically turning it into a SoC).

 

PM me an link if you got it. It looks like something fun I can play with.

 

Why not just decrease the clocks and adjust the voltage manually if you don't want high heat output? BGA isn't necessary for reduced speed and power.

 

A bit OT, but does anyone know if these CPUs are also being phased out by intel?

 

Not all cores are equal, I would rather have 4 un-hyperthreaded core series cores rather than 8 atom based ones.

 

PM'd.

They are being scaled up by Intel. The Xeon D are 14nm Broadwell based and production is going up in the server space as they're highly scalable and their relative performance is immense (beyond Skylake).
AFAIK the Atoms are due to be superceded by the Xeon D as well in even lower power configurations. The Atom cores were 22nm and not quite as efficient, but they are cheap.

Depends on your workload. The performance-per-watt is far superior assuming you can take advantage of it. The Xeon D is a far better example of that since they're using Broadwell cores.
