Hashrate comparison for multiple hash algorithms My question is about the hashrate obtained with same hardware (non-ASIC) on many algorithms.

For example, I've read that Scrypt-N is about half the hashrate of Scrypt. Is that true for all hardwares? Do we have the same kind of relations between hashrates on other algorithms (something like on SHA256 my hasrate would be 10x my ethash hashrate)

Thank you for your answers
It is not true (at least not in a direct ratio) for all hardware. Some algorithms will benefit more from more memory, or particular assembler instructions (eg, AES-NI). Some will benefit more from more hardware threads. So while most algorithms will follow a rough upcurve as system specs improve, you'll se more or less linear ones, and more or less plateauing or decelerating ones, and ones with different slopes on the more or less linear ones.
