The Radeon RX 6600M is actually faster than the RTX 3060 in raster-heavy tests, but overall, it is as fast as the Nvidia card in 3DMark. It also falls behind by up to 13% in 1440p games and is significantly slower in ray tracing games. This SKU will no doubt be ignored by crypto miners as it is slower than the previous gen RX 5600M model.

Slightly disappointing to see the results, hopefully we see laptops with the RX 6600M will at least be significantly cheaper than RTX 3060 counterparts
