Why are new GPU's slower than old ones?

I noticed while looking at EVGA's site that the 650 ti is faster than a 780. I know that a lot of other stuff makes it better but why the lower clock speed?

Its lower clock speed, but more cuda cores, (hypothetical but to easily explain this) so its like having 100 cores with clock speed of one ghz on old cards. Now new cards have 500 cores with 800 ghz. Now theres more than just cores and speed, such as memory and memory frequency, as well as many many other specs. I know the newer maxwells will offer smaller die's, so that means that the communication between segments of the chip themselves are faster since they have smaller distance to travel. And as far as the new lower end cards, they may be alittle slower, but offer half the power consumption, which is a win in the low end department. since your not buying a cheap card to play high end games at max, so whats a few fps on a lower...

And lower clock speed, as since the dies are smaller and the chip itself is more efficient, it requires less to run at the same or better performance. Its kind of like a 1960's corvette vs a new 2015 vette. The older ones had larger engine sizes pistons ect, newer ones are just more efficient and lighter, so faster.

Nice job. You've earned a vowel for your name. : )
