The GPU Advantage scores are based on R9 280x and an AMD FX-8320. I chose these two because the R9 280X is fairly common and has been easy to find published numbers. CPU hash-rate numbers are more elusive so I test on my desktop.
Of course, there are a few problems with this approach. Some coins have faster ATI GPU hash rates. The FX-8320 is slower than the new Haswell chips. Some CPU mining apps take advantage of the Haswell's AVX3 instruction set.
I can test the CPU and get a number, but I still need published GPU numbers.
That's going to put YACoin on the CPU friendly coin list for certain
Please make sure you use the CPU miner optimized for YACoin. I've got published source and binaries on github at http://github.com/Thirtybird/CPUMinerI don't recall seeing anyone publish 280x numbers, but as a 3GB card I would guess it's going to be in the neighborhood of 1.5 KH/sec. If anyone has one and is willing, I'll work with them on settings and we'll see what it can do.
