The average of some runs yields this: Code: [float ]1410.088 GFlop/s [float2 ]1416.99 GFlop/s [float4 ]1424.106 GFlop/s [float8 ]1427.09 GFlop/s [float16]1427.668 GFlop/s [double ]89.354 GFlop/s [double2 ]89.364 GFlop/s [double4 ]89.39 GFlop/s [double8 ]89.39 GFlop/s [double16]89.39 GFlop/s Does this look right? I think the paper GFlop/s figure should be 1433.6 GFlop/s of SP and 89.6 GFlop/s of DP based on this formula and a 1:16 ratio but could be wrong: Code: shader_units*speed*instructions_per_clock = 448 * 1600 * 2 =1433.6 Assuming the above is right and FlopsCL is a pretty accurate reflection of GFlop/s, can someone with a Radeon VII run FlopsCL to determine once and for all what the DP ratio is for that card? There was some question as to if the ratio was 1:4 like they said it was or if it got the full 1:2 treatment, I don't think there was ever a definitive answer.
