Best GPU
#1
Which current GPU produces the most hashes per second?

Is it about stream processors? Then that would make AMD win the race...?
#2
Depends on the algorithm you are attacking but overall best is GTX1080Ti.

Finding one is another story.
#4
The algorithm I'm trying to crack is SHA256.

Has anyone done a comparison before? It would be nice if there was a comparison chart.
#5
Hashmode 1410 (sha256)

1080TI = 4267.7 MH/s

Intel Celeron N3150 (intel openCL) = 4879.1KH/s


I have some 1080, 980, 970 cards in crypto rigs that I will test out asap so you can see the difference.

Eww, no... AMD is trash for cracking, 1080 Ti beats Vega. 1080 Ti is the way to go. If you got deep pockets, then go for Titan V (faster than 1080 Ti)

They are out there, it just depends on which model you want.

There are more factors. ALUs and core clock are one side, but how efficient is the code?

If you have GPU 1 with 1000 core and 1GHz clock rate, and GPU 2 with 1200 cores and 1.25GHz clock rate, then the second would be theoretically faster.

But if a code routine of GPU 1 needs only 100 cycles and with GPU 2 it needs 150, then their speed level is at par.

This is possible because the code is operated in small steps and each step needs 1 to x cycles. If a 64bit-Division needs 3 cycles at GPU 2 and 2 cycles at GPU 1, the latter one needs 1/3 less time.

And then there can be also different instruction sets, with faster instructions coded into the hardware-design.

NVidia is leading especially in code efficiency, that's why they take the lead over AMD.

About to purchase a laptop with GTX 940i onboard - is it worth it, anyone?

laptop GPUs are never worth it

To play around - yes. To do some serious stuff - no.
