was it worth the upgrade from the 7970's to the 780's, specially in crossfire mood !

you sure ?

will this kinda makes an 1250 MHz 7970 within ~ 10% margin from the Titan @ 1000 MHz ? rolleyes.gif

A Titan has an average of 1150 Mhz Core clock when overclocked.




The Titan Memory OC will help the most with the results, has seen here.

Left Axis are the frequencies and bottom axis is the FPS, you see the correlation between CPU clock and GPU Core and memory clock.




The HD 7970 will beneficiate more from GPU Core and Memory OC. But even OCed it will be around 30 - 35% slower than a Titan

how about 2 cards for 2 cards ? does the performance gap shrink or gets bigger or stays the same ?

Synthetic benchmarking apps mean nothing.

in games the GTX Titan is about 25% faster than the 7970 Ghz, overall

And my comparaisons are OC versus OC.

It's not the same chip.

You cannot compare them clock for clock.

You have all the answers you need.


Will the GTX 780 run at the same clocks as the 7970? it depends on the GPU, if you get a good 780 it might, if not then probably no.

I can't find a TPU review for the GTX 780, but given that the 7970 Ghz is only ~25% slower than the GTX Titan the GTX 780 is likely to be ~20% faster, perhaps 25% when both are clocked up.

Is that performance difference worth you selling your 7970 (which is all but bar the BIOS the same as a 7970 Ghz) and buying a GTX 780? that's down to you, if you have money to burn then go for it.

Personally I think that performance gain is not worth nearly enough for the price difference, I would hang on to the 7970 and wait for AMD's response, which is likely to be better value for money.
