Are the Passmark benchmarks so different to everyone elses? I've tended to use their site as a quick ref, but their score for the 4070TIS is well above 4080 and nearing 4090, with a ~20% uplift from the 4070TI.

Sure, it's only 2 samples, so I'm guessing these are overclocked samples - but I've not seen a review getting near this with their OC's.
