yesmanRemember: the SUX 3141 Ti is 60% slower than the SUX 3141 Xt. because it's 5 years older and has no components in common.
Power consumption is part of the equation now too. You’ll often see newer generation hardware that has comparable performance to a last gen model but is a lot more power efficient.
Or you’ll see something equally efficient and equally performing at the same power levels…except you’ll see newer gens or upgraded skus allowed to pull more power
