In terms of performance, it's said to be in the same range as the AMD Radeon RX 6500 XT or the older GeForce GTX 1660 SUPER. It will not be faster than the RTX 2060 12GB.
As we were told, the GeForce RTX 3050 is to have higher performance than GeForce GTX 1660 SUPER, but still lower than RTX 2060 12GB, which is launching next month. What this means is that the card will not compete with Radeon RX 6600 series, but rather the rumored RX 6500XT which is to launch in the first quarter of 2022. Additionally, we also have Intel Arc A128 (rumored SKU name) coming a bit later.
