After presenting its new generation of graphics chips in a mobile version during CES 2021 , Nvidia kicked off hostilities on January 26 so that the Ampere architecture and its cards 2nd generation GeForce RTX are coming to laptops. With more than 70 portable PCs announced, for the players as for the creators, it is also necessary to count, initially, on the arrival of 28 variants for these GeForce RTX 3060, GeForce RTX 3070 and GeForce RTX 3080. An important nuance to understand that we explain below.

Technical characteristics

The mobile RTX 3080 which equips our test machine incorporates a GA104-775-A1 chip, engraved in 8 nm by Samsung. It takes advantage of a maximum clock speed of 1,245 MHz, a total of 6,144 CUDA cores, and 16 GB of GDDR6 memory on a 256-bit bus with a bandwidth of 384 GB / s. The basic TGP is 80 W on this chip, but rises to 95 W on our machine thanks to Dynamic Boost 2.0 which we will discuss next.
