It is not a fair comparison since 4900HS is a 35w chip. A fair comparison would be 4750U, 15w chip with score of 1184/8008
I fully expect Apple's higher end, higher TDP chips to achieve better performance. But they will cost more money.
Like it or not the M1 is competing in a price bracket with the 4900HS.
I don't know many professionals in any industry that are constrained so heavily by power - generally when you're doing professional work, you're not far from an outlet, save some rare use cases like on-location shoots for film and television.
