Not for a benchmark it doesn't.
If you replace a part of a benchmark with your own creation in order to improve your scores for the benchmark, no matter how crappily the benchmark is coded for whatever architecture you're using, you're corrupting the benchmark. Plain and simple.
For a game? Sure. I'm ALL FOR IT. But for a benchmark? No. Otherwise, you'd have to be dependent on a driver team to optimize for every game on the planet in order to get similar performance.
