Thanks. Does the article explain why MilkyWay is so much faster on AMD Hardware, and so slow on Kepler vs. Fermi? Does it use DP?
I was in the same question about this, but i dont know this one .
Maybe not optimised at all .
If we remove the 7970, what is the most incredible ( who is sometimes even 10x faster ) , is the lost of performance in compute against the GTX580 ... ( personnally i will have use a GTX480, the 580 was allready slower of it )..
Last quarter of 2011, Not the best.... Its funny enough as AMD is now leader in global GPU market... ( under Intel ofc ) ( The lost in discrete gpu market is essentially due to 2 factors on last quarter 2011, essentially cause AMD have move low end class gpu to the CPU, but the fact AMD was ready to launch a new series is ofc a good part of it too ... )... Its start to be really complicated with the move on CPU of gpu low end class, to compare both....
You know thoses numbers are essentially a report of Low class gpu, as middle and high end dont represent both, more of 15% of the total market of gpu ( by brand ).
For give you a funny example, the sales of the GTX560 ( all version include TI and non TI ) have doubled since September-October 2011... passing from 4% to 8% ...
For be honest, i dont count too much on gpu number sales on this first quarter: 7970-7950 have been launch in january, 680 is the only card from Nvidia.. and all cards are not cheap at all. ( including 7870-7850 )... the availability of both 7970 and 680 on their respective launch have been far of enough and the market is quite discorded. We was all wait for a massive 2012 Tsunami of cards, new series and for both AMD and Nvidia, this is not the case.. the card appears slowly on the market ( with AMD who have at least now a panel of cards: 7750-7770-7850-7870-7950-7970 vs only a the GTX680 from Nvidia )..
Its excellent to see the GTX560 sales a lot at his respective price, or this is by far not the best card yet lol, at least performance wise. ( 7870 is on 580 performance level )
