I'm a bit disappointed that a project task last ~ 16 seconds with the Milkyway 1.36 ATI app on one FuryX VGA card (1 WU/GPU).
I looked to other PCs, e.g. hostid=590597 with 'R9 200 Series - Hawaii' VGA cards. This VGA card have just 44 ComputeUnits (CUs) A task last ~ 15 seconds.
The/my FuryX have 64 CUs. But a task last ~ 16 seconds.

Is there something wrong - possibilities to optimize/fine tune?

Thanks.


Take a look at memory speed and whether the R9 280 has 128bit, 256 bit or 384 bit thruput speeds, the faster the memory and the faster the bits get transferred at one time, the faster the card crunches. It's not JUST the CU's anymore.


It's not just memory speed here. Since MW use double precision calculations (DP) the card's DP compute capability is the real driver.

R9 280 series DP = 1/4 SP
R9 290 series DP = 1/8 SP
R9 Fury X series DP = 1/16 SP

The R9 280 series may not be the fastest single precision performer but the 1/4 DP to SP ratio makes it the leader in double precision for the $.

"Niceee ..7970 rocks :-))" actually i have 15-16 second per one task.

I have two graphics cards, 7970, two PCI slot edition of the good cooling. Which never goes above 60 degrees celzius.no thortle
but I can not get over 200k rac day. now.. use only clean win 10 edition, no other soft or browsing..
when I've watched my logs a year or more ago. and to the same card i had about 400k+ rac. + 1 similar card Ati.

so it looks like that the optimization tasks is worse.... -100k rac ,same mobo or cpu(12 core)

I find the data and put it here.
  unfortunately I do not have motherboards where i can inserted three video card, the width of two PCI slots cooling. for test.
