NVIDIA GeForce RTX 3080 Mobility GPU Specifications and Reference Leakage, in Line with an RTX 2080 Ti



The specifications of NVIDIA’s GeForce RTX 3080 mobility graphics card are confirmed in a list on Geekbench. The entry was discovered by TUM_APISAK and shows the next generation RTX 30 series mobility GPU running in the OpenCL test series.

NVIDIA GeForce RTX 3080 mobility GPU to include GA104 GPU with 6144 cores, 16 GB memory and 1540 MHz clock in Max-P variant, in line with an RTX 2080 Ti

Just a few days ago we got to see the references and specifications of the GeForce RTX 3070 GPU for laptops along with the first entries for the NVIDIA GeForce RTX 30 series mobility range along with some preliminary specifications. Also, based on the clock speeds alone, we can say that this is the Max-P variant of the GeForce RTX 3080 instead of the Max-Q variant which offers conservative clock speeds to provide higher efficiency and battery times.

NVIDIA plans to design GeForce RTX 3080 SUPER & GeForce RTX 3070 SUPER graphics cards

So when it comes to the specifications, the NVIDIA GeForce RTX 3080 Mobility will contain 48 SM on the GA104 GPU SKU (presumably GA104-775). This chip will contain a total of 6144 cores and a maximum clock speed of around 1540 MHz. The graphics card also has 16 GB of VRAM that goes over a 256-bit wide 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:

Preliminary specifications 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 3080 Mobility was tested on an ASUS ROG Zephyrus GX551QS next-generation laptop that comes with AMD Ryzen 9 5900H CPU with 8 Zen 3 cores, 16 wires, a base clock of 3.30 GHz and a boost clock of up to 4 , 55 GHz. You can see CPU reference values ​​in this previously reported article.

In terms of performance, the GPU scored 139,181 points in the OpenCL test. The score puts the GeForce RTX 3080 mobility on a par with the GeForce RTX 2080 Ti & GeForce RTX 3070 Desktop variants. But at the same time it is slower than the GeForce RTX 3080 desktop by 30%, which can be expected since the variant not only offers lower cores, but also comes with much lower clocks, even though it is a Max-P variant. The score also puts the GeForce RTX 3080 mobility around 25% faster than the GeForce RTX 3070 mobility results we saw before.

So essentially you will get RTX 2080 Ten performance levels in a GPU, which was not the case in the previous generation.

Portable manufacturers 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 Tiger Lake-H 11th Generation CPU Series at CES 2021.
