HardOCP released the RTX 2070 review 2 full days before the NDA lift and it looks like last week's leaks are now confirmed. The factory overclocked RTX 2070 models are slightly faster than the GTX 1080, with the stock RTX 2070 most likely on par with the previous gen Pascal GPUs. On the other hand, the price for the overclocked RTX 2070 models might be a bit too spicy.
