calculating wpa speed (gpu)

[Difermo]

I'm searching, but I can't find, how to calculate wpa speed base on gpu.
I only manage to find that speed is based on number of cores and core frequency
I found this site with lots of gpu tested

So questions:
1) how good is NVIDIA GeForce GTX 860M - 2 Go GDDR5 for wpa cracking with cudaHashcat, and what would be WPA speed? (is there any formula to calculate it)
2) is there any speed boost if it is GTX 860M - 4 G0 GDDR5 ? (what i learned say no, but i need to ask)

Even for laptop?
I'm buying new laptop and for price <1000 euros, that's the best gpu card I coud find

GTX 860M with 2gb have core speed 1029 MHz & SP 640 MHz  ||| WPA = ?

GeForce GTX 750 Ti have core speed 1085 MHz & SP 640 MHz  ||| WPA speed = 53098

Can we say that 860M would have around 50000 (not less)?
I see that Radeon HD 7970M and HD8970M are better but use more watts and that means more heat

WPA-PSK hashes are salted with the SSID so in theory cracking speed depends on the byte-length of the SSID. If the SSID is longer in character-length, that's more bytes that have to be processed during hash computation. Hashcat pre-computes the hashes on the fly so the longer the SSID, the longer hashcat will take during pre-computation before the hash-comparison sequence.

[HTH]

For a laptop that wont be too bad, definitely get the 4 gb version as it has a different chipset which raises the total computational power from 1300 gflops to 2100 gflops.

Obviously a 980M would be ideal as it has ~3400 gflops but you should get...

~120 thousand tries per second with an 860M, if the ratio from my machine to yours holds.

Further,

you would get ~ 6 billion md5 hashes a second. So I'd say for your average bear an 860M would more than do the job. OFC for what you spend on this laptop you could make a kickass desktop but thats not really the point

Ok didnt know that for SSID. Thanks

So @HTH what I understand with GTX 860M 4gb GDDR5, I will have WPA speed ~120 000 tries/s?

I know that I can get good desktop for same price. But I need portable because this one laptop is old. And to be honest it use less power, I dont plan to be professional, and IT isn't my job speciality. I'm not always at home so laptop is best choise.

This one was number1

Yes, the 860M with 4 gb will give you ~120,000 tries/second, the 2 gb would be about 80,000.

THANKS @HTH

Well I would be happy with 80 000 !! that would take 9 days for my custom wordlist (just to compare it is 723 days with speed i have  1000t/s )

One more question and I'm done

GTX 850M 2gb DDR3 comparing to GTX 860M 2gb GDDR5.  Will it give ~70 000 tries/s or less?
The only diference comparing to GTX 860M is DDR3 and lower core speed of 93 (936 MHz for GTX 850M)

[HTH]

it -looks- like that would be a viable guess (70k/s) I mean.

No promises though.

[Difermo]

More then 50k/s is fine !!

THANKS AGAIN
