Thanks for sharing your benchmarks. I'm not used to such a big
difference between real vs. virtual, is this usually the case with
opencl formats or is this just the case when running john -t (as
opposed to a real job).
Are the shown ~430K c/s virtual realistically reachable or should one
calculate with the 102K c/s? Since this is the highes virtual value
(429K) seen so far: What GPU was used for it? (Should I know it by the
device name "Tahiti" ?)
According to [1] AMD Radeon HD 7970 Ghz Edition is currently one of
the most powerful GPUs, would be great if we could run the test on
such a card.
