Results from dpbench of PCA workload (running on a laptop with 11th Gen processor and Iris Xe graphics):

workload numpy dpnp CPU dpnp GPU size
pca 1.2 s 3.6 s 1.2 s 1048576

demonstrates dpnp execution time on CPU which is 3 times greater than one of NumPy.

The numbers with dpnp=0.12.0:

workload numpy dpnp CPU dpnp GPU size
pca 0.53 s 2.01 s 0.93 s 1048576

The result is faster, but still not in target.
