I really don't know what to make of omeds unusually high scores to be honest. I have no problem at all believing his 4770K@4.8 is faster for this specific benchmark than my 3930K@5.1 or Groove's 3930K at whatever speed he was running at the time. However, he's also making up for a ~100mhz or more disadvantage in gpu core speed. I can't speak for Grooveriding but my Classifieds are not error correcting at +700 on memory (7400mhz), they do suffer from error correction at +800mhz (7600) @ default voltage. Adding just a touch of voltage solves that though.
What we've seen in the cpu bench threads on here is that per core a Sandy Bridge needs as little as about 200mhz to as much as about 500mhz to be on par with Haswell depending upon the specific bench. I think that's a pretty fair assessment, someone can chime in if they see it differently. From his 4.2GHz scores posted today, If I were to run my gpus at the speeds his are running I can't even match him @5GHz. That's an 800MHz gap, I'm not sure Haswell is that good. Maybe we have found a benchmark that just absolutely loves Haswell, still seems odd as it's primarily supposed to be a gpu taxing benchmark. It's all in fun though, I'm sure it will work itself out as time goes on and more Haswell's fill the chart and give us a better understanding of just how well Valley responds to them. I'm personally not going to cause the thread organizer stress over the issue as he's busy enough with the chart as it is, and I'm sure we all appreciate these fun little competitions.
Edit: Does anyone know what speed Piklar's cpu was running at for the benchmark, because he's running a 4770K as well with virtually the same clocks on his gpus as omeds.
