Ok, the 204.56 MK/s and 165.57 MK/s are those 2 speeds are added together to equal 370.13 MK/s?

No. The first value on the left is the combined speed of both the CPU and GPU.

The second value (165) is measuring the GPU speed only. it means the CPU speed is actually about 39 MK/s.

Oh ok then, so what gpu's can go at least or close to 1 billion keys with kangaroo?

Sorry for run at begin CPU is hike  normal GPU run  110-130 MK/s
