I don't expect a new MHz war anytime soon. The biggest thing Intel will have to offer with Skylake is battery life, and AMD and Nvidia are both working on that too. Process shrinks aren't the only ticket to saving power.[/QUOTE]
This is completely my personal opinion, but I like to offer my viewpoint. I think that processors are a lot less about themselves and really about the platform delivered with them. Skylake being the perfect example. New ram, thunderbolt 3, and the biggest example; wirelessly powered all in one desktop... possibly.
My point is really driven by the simple fact that professional camera sensor tech has plainly exceeded computer tech. Highly magnetic sensors in red cams gather light data that current computers can't translate. Raw film shot on these cameras debayered on computers "in about five years" will be much higher in quality.
This sensor tech is becoming affordable and everyone will be shooting with sensors that present day computers can't handle. Apple will have competition if it isn't driven towards graphics improvements yesterday. The same for Intel, AMD, NVIDIA, AMD, and all the rest.
Apple is the (in my opinion) the king for film and photo editing: And present time no one's graphics are keeping up with new sensors capabilities. Redray made a red rocket graphics card that is ridiculously expensive just to real time edit very high quality 4k and to improve data gathering properties of current gen cards as well as workflows for their cams.
Skylake is more of a System On Chip step forward as a processor than anything else. The communication time between the processor and graphics processing is a huge advantage of developing this tech.
Another example of what I would like to call "the graphics war" is that dual dGPU's are supported by FCP. A step I expect everyone will follow in as short of time as they can. That being the case I would also expect that the processor and it's SOC graphics would also be supported at the same time as an "external GPU or external duel or triple GPU's". Not to mention 5K display just came out.
I like skylake for a lot of reasons but it's biggest steps forward will be on graphics improvements and in engineering SOC tech for mainstream and one day professional users.
Finally as pointed out before by a few others on this thread processor's aren't the only thing that shrinks, so do external components and no faster do they shrink as when they are integrated into motherboard components.
I'm not a computer engineer and likely not the smartest person on this thread, this is just my humble viewpoint.
