The specifications of the NVIDIA GeForce RTX 3070 mobility video card have been confirmed in a list on the Geekbench. The list was found by TUM_APISAK and shows the next generation RTX 30 series mobility GPU running on the OpenCL test suite.
NVIDIA GeForce RTX 3070 Mobility GPU features GA104 GPU with 5120 cores, 8 GB memory and 1300 MHz clock in Max-Q variant, on the same level as an RTX 2080 SUPER
A few days ago, we saw the first listings for the NVIDIA GeForce RTX 30 series mobility line along with some preliminary specs. It appears that these specifications may turn out to be true, as they correspond to today’s leak. Furthermore, based only on clock speeds, we can say that this is the Max-Q variant of GeForce RTX 3070 instead of the Max-P variant, which offers much higher clock speeds.
Therefore, reaching specifications, the NVIDIA GeForce RTX 3070 Mobility will feature 40 SMs in the GA104 GPU SKU (presumably the GA104-770). This chip would have a total of 5120 cores and a maximum clock speed of up to 1300 MHz (~ 1290 MHz). The video card also has 8 GB VRAM that works on a 256-bit bus interface, but it remains to be seen whether NVIDIA is using 12 or 14 Gbps DRAM modules for its mobility line. In the case of 14 Gbps, the GPU will be able to offer a maximum bandwidth of 448 GB / s.

Preliminary specifications from NotebookCheck also seem to indicate that the Max-Q variant will have a TGP between 80-90W while the fastest Max-P variant will feature a 115-150W TGP. The NVIDIA GeForce RTX 3070 Mobility was tested on an HP Omen 15 laptop that also had the Intel Core i7-10870H and 16 GB of DDR4 memory installed.
In terms of performance, the GPU scored 110839 points in the OpenCL test. The score places GeForce RTX 3070 mobility on the same level as the GeForce RTX 2080 SUPER, but at the same time, it is slower than the GeForce RTX 3070 for desktop by 17%, which should be expected, as the variant does not only offer smaller cores, but it also comes with much lower clocks being a Max-Q design. It looks like the Max-P variant should close the gap and bring the performance gap to less than 10 percent, but that remains to be seen.
Notebook makers will also offer advanced and enthusiastic configurations of NVIDIA GeForce RTX 30 Ampere GPUs with AMD’s Ryzen 5000H ‘Cezanne-H’ CPUs and Intel’s 11th Generation Tiger Lake-H CPU line at CES 2021.
