So node shrinks bring more money and smaller, faster chips – while using less power than before…it’s just a win all round. Simple, right?
it is a trade of it is not all of them faster chips will be previous arch with improvements or a completely new arch scaled up. Smaller would just be making the same chip with a small die area. Less power comes with a tinier chip or a larger low clocked chip.
It is the opposite of simple but there is an optimum point a prime example of this is Kaveri which completely sucks beyond 3,5GHz for efficiency but does good/great before that.
So we’re supposed to be getting 20nm graphics cards next, but the evidence against that happening continues to mount.
Clearly it does not the increase is not that big actually I posted a chart of production costs of the Fermi cards and even with the chart the card wouldn't be more than 20 dollars more expensive. Actually the price of video cards at Nvidia increased dramatically more like 300 dollar on average on high end models early on especially GK104 being gauged for what small chip it actually was.
Clearly he has no idea about actual costs and doesn't even comprehend that smaller chips are less likely to fail so yields per wafer will be higher. And there would also be more chips on the wafer as always great for the small chips.
I’m sure you noticed the lack of mention of graphics – but the important part is the performance. TSMC claims 30% higher speed, but that’s compared to their low-power 28nm process! Compared to their high-performance process it would barely be 10% faster, if anything. I believe TSMC’s 28nm HP would likely be faster for graphics cards than their 20nm-SoC.
Here he makes a valid point but that is completely negated by his own idiocy by stating that there would be only a 10% gain in clock.
Clearly speed is determent by 2 things one is the design itself and and the other is clock now even if the clocks gained very little at the same voltage that would still leave us with a chip that can be 1.9x more dense according to TSMC themselves.
I can go on and on but we will infact see 20nm gpus and perhaps not the big ones (yet) but they will be here.
