A8-5600K bought for a cheap private server 1,5 years ago https://en.wikipedia.org/wiki/List_of_AMD_accelerated_processing_unit_microprocessors#Virgo:_.22Trinity.22_.282012.2C_32_nm.29 I can set up system stats if you want proper figures, but far from full load with 250Mbps average bidirectional traffic. > The AMD's seem nice if you don't pay for watts, want ATI opencl > GPU performance on die, can utilize their cmt setup better > than htt, or just want a decent cheap cpu (which could indeed be > interesting to evaluate for lower bandwidth like this 370Mbps). > I currently have free hosting for this machine, so power and traffic not an issue.
