Your link is an Intel chip in research that's being designed to mimic a human brain, built with memristors.
This one is about the commercial launch of Knight's Corner, an add on card by Intel which essentially stuffs 50 Pentium cores with enhanced vector instructions onto one chip.
This is the fruit of the troubled Larabee project, which aimed to build a GPU using x86, but even with Intel's extreme process node advantage, it could not get fast or power efficient enough to even come close to modern GPUs (it was several generations behind, and so was never released commercially).
Extreme process node advantage? They are just one generation ahead at most (2 years). It's not nearly enough to overcome the architecture's inefficiency when it comes to doing GPU stuff, nor is it big enough to overcome the architecture inefficiency for power consumption vs ARM chips for that matter.
By published data, Intel 45nm, with products out in 2007, switches as fast as TSMC 28nm, with products out January this year.
They only have ~2 years of advantage on density, but they reliably have 5+ years advantage on speed. I'd call that extreme.
I absolutely believe that once Intel actually releases atom cpus on their best process (so far, they have mostly used them to fill out production on old processes), it will beat ARM on performance/watt. When they move atom to a competitive uarch (OoO ffs), the race will stop being a race.
That's indeed what I was referring to. Intel's processes are typically superior to AMD/GloFo's at the same node, and miles beyond the respective bulk processes at TSMC. They also get there first.
Is it really 30% of your silicon even discounting caches? I'd love to see some analysis (and comparison against arm) of this from an expert; I've heard everything varying from "x86 instruction decoding is majority of the power drain" to "ISA doesn't matter, it's everything behind the frontend that matters" and it's hard to find actual analysis. I guess partly because this is all highly confidential.
And I know even ARM has instructions that make chip designers want to get all stabbity (ldm, stm)

Pretty cool couple of days for Intel, news wise.
