Simply by going into smaller integration scales. For the same frequency you have smaller currents, or you can pump up the frequency and get the same currents. Thats they way it is going for years now, i wonder why you asked that. Better interconnects are the one with lower resistance and lower...

To get more frequency you need to make better transistors(smaller , with less curent draw and less leakage currents) and better interconnects. Interconnects are limiting factor due to signal delay (for their length) and their capacitance(due to their geometry (length, width) and distance from...

Well i doubt hand tuning can get you half the size and twice the speed (improvement up to 25% less size and 25% more speed maybe), but even so you implicitly agree that transistor count and interconnect complexity are the major factors limiting the frequency. If a hand tune doesnt reduce the...

SilentGuy your arguments are all based on some sort of weird argument that "the chip may have a large number of transistors and interconnects globally, but this doesnt affect the operations of transistor and interconnects locally". It just makes nosense to me. For example you say Now it doesnt...

You may have a point with the hand tuning, but i still dont believe it is the main reason. The increased transistor count (increased power, more difficult to cool) and the increased complexity(more complex interconnects which leads to signal interference, signal attenuation and signal delay...

I believe nvidia was able to raise the clock so much mainly due to the fact that the ALUs got simpler, 32bit scalar instead of 128bit vec4. CPUs can achieve higher clocks cause they have less transistors, so for the same frequency less heat dissipation and therefore less power demand...

Basically "we dont care " what happens when cpu is the bottleneck. My point of this thread is this question:"If we could make a PCie card with the RSX on it where this card would be placed in terms of perfomance relative to the other cards?" (when something is CPU botllenecked then this...

This is the point that made me thought that Sony owns the designs since in order to be a direct customer to a chip fab(and order the fab to manufacture a chip in which sony gives its 'RSX' name, Xbox has nvidia's logo printed on the GPU and MainBoard chip, Xbox360 has ATi's Logo on these chips)...

Ok so it is a 7800 GPU with half the ROPs and half the memory width which means (in my opinion) at average its perfomance would probably be between 60 and 70% relative to the perfomance of a 7800GTX. Sony holds the recipe means that it has bought all the patents from nvidia, or that it is an...

Well, how does the graphics chip RSX of PS3 relates to nvidia? It is nvidia designed and given another name by Sony or is it designed and manufactured by Sony? In the first case that nvidia is behind the chip what is its nearest, in terms of perfomance, PC-GPU? Something in the G7x family(e.g...
