[citation][nom]jprahman[/nom]Yeah the 48 core terrascale CPU isn't designed to be put into production, it's just for researchers.Server code can't really run on the GPU part of a APU, at least not web/file server code. The GPU part of a APU can only run massively parallel floating point code, web/file servers don't use much if any floating point math so the APU would be of no help.I could see a atom with 16 cores doing well in a cloud computing server. A major tenet of cloud computing is to use low power/low cost CPUs in large numbers and so a low power 16 core atom would be a good fit.[/citation]
lets put this in a way they people can understand better. a watt per core.
xenon 3.33 (3500-series "Bloomfield") would be at best, 16.25 watt per core, and at worst 32.5 watt per core, depending on if you count logical as being as good as a physical, i dont know how that works server side, but im assuming its better than desktop.
the best xeon, (6500/7500-series "Beckton") which i doubt they use, comes to 16.25 watt per core, on physical, and 8.125 watt per core if you count logical.
now the atom side, i went with the top model, and the lowest power model.
the lowest power, daimondvill dual core ht, comes in at 4watt per core, or, 2 watt if you go logical
and the best one, pineview, which comes in at 6.25 watt, and 2.75 watt pr core.
now lets take a look here, at a 1000 cores and in best conditions (these servers i assume use it in the 10000+cores per service minimum, probably that amount of cpus) now servers on the scale of hotmail and the like dont upgrade often, at least i dont think they would, but they make big upgrades, so Microsoft may be using even more inefficient processors.
but here, 1kwatt is 1000watt. and kwatt here will be measured in hours, and where i live 1kwatt equals 11 cents.
xeon 16.25kwatt = 1.7825$ an hour
xeon 8.125kwatt = .89375$ an hour
atom 2kwat = .22$ an hour
atom 2.75kwatt .3025$ an hour
lets blow this out, to 100000 cores to give you a better picture.
xeon = 178.25$ an hour 4,278$ a day 132,618$ a month 1,561,470$ a year
xeon = 89.375$ an hour 2,145$ a day 66,495$ a month 782,925$ a year
atom = 22$ an hour 528$ a day 16,368$ a month 192,720$ a year
atom = 30.25$ an hour 726$ a day 22,506$ a month 264,990$ a year
and this is powering the cpu alone, and those numbers are probably higher than i just mentioned. i just expanded it to the point people can see the real world difference
