Re: SolidCoin v2.0 features new hashing algorithm, faster on CPUs

Quite well since that's up there with the fastest. I haven't quite benchmarked the new algorithm extensively (because it's not completely optimized yet) but it's about 1000 times more intensive than the last method on CPU. And the changes should make GPUs not a viable option for some time. It's utilizing SHA256 and one of the new SHA-3 candidates "BLAKE" along with some other features which the CPU is better at handling than GPU.

 I've had a look at "BLAKE" and it seams o be using similar basic operation to the current SHA-256. How is it less efficient at GPU mining then the current SHA2/256 algorithm? It does not include the non-linear elements Maj and Ch from SHA2, but these were not the main selling points of the GPUs anyway.
 I am not a GPU expert, so there is probably something major that I missed here, can somebody please explain it.
