In this case, the new items will become the world’s first video cards based on 6-nanometer GPUs. Intel’s Arc GPUs are also expected to be 6nm, but will come out at a later date. There are also rumors that AMD will switch to the 6nm process technology of the Radeon RX 6600 XT and Radeon RX 6700 XT.

But in reality (bnz Infinity Cache) we are expecting values at the level of 128 and 112 GB / s, respectively. The older model is assigned GDDR6 memory chips with a frequency of 16 GHz, the younger one – with a frequency of 14 GHz.
The power consumption of the older model will be 107 W, the younger – 53 W. The older one will receive a two-slot version and a six-pin connector for additional power, the younger one will be single-slot and low-profile. In both cases, there will be two connectors: DisplayPort and HDMI.
