Question GTX 1050 ti or HD 7970 ?

[Cpumaxusage]

Which would have better performance for gaming I have heard the hd 7970 out performs the gtx 1050 ti in about 15 percent but I have seen benchmarks which proves them wrong would they just be similar to one another?

So the HD 7970 is faster than the Gtx 1050 ti? Even though it has 1 less gb of vram?
