The specifications of NVIDIA’s GeForce RTX 3070 mobility graphics card are confirmed in a list of Geekbench. The entry was detected by TUM_APISAK and shows the next generation RTX 30 series mobility GPU running in the OpenCL test series.
NVIDIA GeForce RTX 3070 mobility GPU to include GA104 GPU with 5120 cores, 8 GB memory and 1300 MHz clock in Max-Q variant, in line with an RTX 2080 SUPER
Just a few days ago, we saw the first listings for the NVIDIA GeForce RTX 30 Series Mobility range along with some preliminary specifications. It seems that these specifications may end up being true since they match those from today’s leak. Also, based on the clock speeds alone, we can say that this is the Max-Q variant of the GeForce RTX 3070 instead of the Max-P variant which will offer much higher clock speeds.
So when it comes to the specifications, the NVIDIA GeForce RTX 3070 Mobility will contain 40 SM on the GA104 GPU SKU (presumably GA104-770). This chip has a total of 5120 cores and a maximum clock speed of up to 1300 MHz (~ 1290 MHz). The graphics card also has 8 GB of VRAM that goes over a 256-bit wide bus interface, but it remains to be seen whether NVIDIA uses 12 or 14 Gbps DRAM modules for the mobility range. In the case of 14 Gbps, the GPU will be able to offer a maximum bandwidth of 448 GB / s.
NVIDIA GeForce RTX 30 Mobility GPU Lineup:
|GPU name||NVIDIA GeForce RTX 3060||NVIDIA GeForce RTX 3070||NVIDIA GeForce RTX 3080|
|Process node||Samsung 8nm||Samsung 8nm||Samsung 8nm|
|Base Clock||~ 900 MHz||~ 1100 MHz||~ 1100 MHz|
|Boost Clock||~ 1700 MHz||~ 1620 MHz||~ 1700 MHz|
|Memory bell||14 Gbps||14 Gbps||14 Gbps|
|Memory size||6 GB||8 GB||8/16 GB|
|Bandwidth||336 GB / s||448 GB / s||448 GB / s|
|Start||Q1 2021||Q1 2021||Q1 2021|
Preliminary specifications coming in from NotebookCheck also seem to indicate that the Max-Q variant will have a TGP between 80-90W, while the faster Max-P variant will have a TGP of 115-150W. NVIDIA GeForce RTX 3070 Mobility was tested on an HP Omen 15 laptop which also had Intel Core i7-10870H and 16 GB DDR4 memory installed.
In terms of performance, the GPU scored 110839 points in the OpenCL test. The score puts GeForce RTX 3070 mobility on a par with GeForce RTX 2080 SUPER, but at the same time it is slower than desktop GeForce RTX 3070 by 17%, which can be expected since the variant not only offers lower cores, but also comes with much lower clocks as a Max -Q design. It seems that the Max-P variant should close the gap and bring the performance difference below 10 percent, but it remains to be seen.
Portable manufacturers will also offer high-end and enthusiastic configurations of NVIDIA GeForce RTX 30 Ampere GPUs with AMD’s Ryzen 5000H ‘Cezanne-H’ CPUs and Intel’s Tiger Lake-H 11th generation CPU series at CES 2021.
