R9 270x compare to R9 280X
#1
Well i thought that if i buy a 280X i would double h/s in oclhashcat

the R9 280X  (2048 Stream Processors [font=helvetica, arial, sans-serif]Tahiti[/font]on wpa2 @ 1050 Mhz clock= 147.4 kH/s 

vs

the R9 270X  (1024 Stream Processors Pitcairnon wpa2 @ 1050 Mhz clock= 92,000 h/s

i'll get better performance with 2 
R9 270X  (1024[font=helvetica, arial, sans-serif] Stream Processors Pitcairn
on wpa2 @ 1050 Mhz clock= 2 X 92,000 h/s= 184,000 h/s[/font]


[font=helvetica, arial, sans-serif]anybody else experience that?[/font]

[font=helvetica, arial, sans-serif]is it  because of the processor is different [font=helvetica, arial, sans-serif]Tahiti vs [font=helvetica, arial, sans-serif]Pitcairn?[/font][/font][/font]

That's because the 270X has 1280 stream processors. 92000/1280*1024=73600*2=147200. You're welcome Wink

Well that was bad on my part. lol, i see it now :-)

so to double the speed of my 270x would need a r9 290
