Are my GPU results reasonable?

I was trying to run
this example to see results of a quick benchmark on CPU and GPU. After it's completed, my CPU results at Read+Write and Double Precision Matrix Multiplication seemed weird to me.
After that, I tried the benchmark provided by MathWorks Parallel Computing Toolbox Team, which was given at following link.
Results from that benchmark is below.
Is everything alright with my CPU and GPU? It seems that my GPU is slower than CPU at double precision operations. Since my GPU(GTX 1050 Ti) is not an outdated GPU, its results at double precision seems wrong to me. Maybe I am wrong or can you provide me any better benchmark(s) to diagnose if there is a problem or not.

Looking at the Wikipedia page for NVidia GeForce 10 series GPUs, the benchmark results seem to agree. The double precision GFLOPS number published there is 61.9 GFLOPS for the base clock and 66.8 GFLOPS for the boost clock. The single results are also close to your results -- 1981.4 and 2138.1 respectively -- but these are many times faster than the doubles. If you look at the other GTX cards in the table you will see that this trend continues for other cards in the GeForce 10 family -- the single performance is many multiples faster than doubles.
