3B has pretty much the same GPU (it might be upclocked), so shaders won't work much better. ARM really improved memory bandwidth from the A7 to A53 uncore bits, which probably helps as much as the CPU speed bumps... at the cost of it running quite a bit hotter. I read an Anandtech article where they compared Samsung arm32 to arm64 chips, and the benchmark differences were actually quite similar to Pi2->3.
