When I load the fglrx ati proprietary driver (11.1) for the 5450 card, then= I get throughputs of about 2GB/s in both directions.=20
Running the same test in same environment on the HD5970=20 with the gallium drivers and kernel mode setting and pcie_gen2 activation, i get about the same figures as above. With fglrx for 5970, then 5970 only performs well in CPU->GPU with about 2G= B/s and only 0.5GB/s in GPU->CPU direction=20 I have included the test and configuration output for both cases (fglrx and radeon) and also code for the testprogram might you want to reproduce this case. --=20 Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=3Demail ------- You are receiving this mail because: ------- You are the assignee for the bug.=
