The RTX 3070 mobile series uses 5,120 of the 6,144 cores. The raytracing and tensor cores on the chip were also improved according to Nvidia. With Turing all shaders could still execute FP32 or INT32 instructions. The RTX 3070 however wont use all ALUs on the chip. The GA104 chip offers 6,144 FP32 ALUs of which half can also execute INT32 instructions (i.e. The similar named RTX 3070 desktop card is significantly faster. On average it should be similar to the old RTX 2080 Super Mobile and therefore best suited for QHD - 4k gaming. The performance depends on the TGP setting and cooling of the laptop. There is no more Max-Q variant (formerly used for the low power variants) but every OEM can choose to implement Max-Q technologies (Dynamic Boost, Whispermode). The GPU supports eDP 1.4b to connect the internal monitor.
As package the notebook graphic card uses GB5-256 and the chip size is 40x40mm. It supports PCIe 4.0 and will be available in two different variants from 80 to 125 Watt (TGP). It is based on the GA104-770-A1 Ampere chip and offers 8 GB GDDR6 graphics memory with a 256 Bit memory bus.
The Nvidia GeForce RTX 3070 Mobile (for laptops, GN20-E5, Max-P, ID 249c / 249d) is the second fastest Ampere graphics card for notebooks in early 2021.
