Power configurations of NVIDIA’s GeForce RTX 30 mobility GPUs that include GeForce RTX 3080, RTX 3070, and RTX 3060 have been detailed. The NVIDIA GeForce RTX 30 series will be launched in both Max-Q and Max-P flavors, with different core, clocks and memory configurations.
NVIDIA GeForce RTX 30 Mobility GPU Power Configurations Leak Out, GeForce RTX 3080 Up to 165W For Enthusiast Notebooks
There are three power profiles where NVIDIA GeForce RTX 30 Mobility GPUs will work. These include the base TGP (Total Graphics Power), cTGP (Configurable Total Graphics Power) and PPAB which is a dynamic AI-accelerated boost range. PPAB will mostly be optimized by laptop manufacturers for their solutions based on cooling characteristics.
For Max-P variants, PPAB will supply 15 watts of extra power to the GPU, while in Max-Q variants it is rated up to 20 watts. The reason why Max-Q variants offer a higher PPAB range is that they have lower TGP to begin with, while the Max-P variants are delivered with higher minimum TGPs.
Now there is a report from NotebookCheck that NVIDIA has removed the Max-Q and Max-P labels from the GPUs, and that OEMs are free to decide the TGPs they will set for laptops running GeForce RTX 30 Mobility GPUs. This means that the minimum TGP should therefore be intact, but other calculations such as cTGP and PPAB sites will depend entirely on what OEMs plan to do with them.
NVIDIA GeForce RTX 3080 16GB Mobility GPU – Laptops From $ 1999 US
The NVIDIA GeForce RTX 3080 graphics card will be the flagship offering in NVIDIA’s RTX 30 Series portable GPU family. NVIDIA GeForce RTX 3080 Mobility has 48 SMs on the GA104 GPU SKU (GA104-775). This chip will contain a total of 6144 cores, a base clock of 1245 MHz and a boost clock of 1710 MHz.
The graphics card also has 16 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 its mobility setup. In the case of 14 Gbps, the GPU will be able to offer a maximum bandwidth of 448 GB / s.
The Max-Q variant of the GeForce RTX 3080 Mobility GPU has a boot TGP of 80W that can be configured up to 165W. GeForce RTX 3080 Laptops start at $ 1999 US and will offer 100+ FPS with 1440p resolution in multiple game titles.
NVIDIA GeForce RTX 3070 8GB Mobility GPU – Laptops From $ 1299 US
NVIDIA GeForce RTX 3070 Mobility will have 40 SM on the GA104 GPU SKU (presumably GA104-770). This chip has a total of 5120 cores, a base clock of 1290 MHz, and a boost of up to 1620 MHz. The graphics card also has 8 GB of VRAM that runs across a 256-bit wide bus interface, but it remains to be seen whether NVIDIA uses 12 or 14 Gbps DRAM modules for its mobility setup. In the case of 14 Gbps, the GPU will be able to offer a maximum bandwidth of 448 GB / s.
The TGPs for the GeForce RTX 3070 will also have a basic TGP of 80W, but can only be configured up to 150W. GeForce RTX 3070 laptops start at $ 1299 US and will offer 90 FPS 1440p games.
NVIDIA GeForce RTX 3060 6GB Mobility GPU – Laptops From $ 999 US
Finally, we have the GeForce RTX 3060 6 GB, which was also announced for the desktop segment today, but with 12 GB of GDDR6 memory. Both desktop and mobility variants have the GA106 GPU, but the portable variant comes with 30 SM units activated, resulting in a total of 3840 CUDA cores. The graphics chip will contain clocks that start at 1283 MHz base and go up to 1703 MHz boost frequencies.
As mentioned earlier, the GeForce RTX 3060 comes with a 6 GB graphics card with a total of 6 GB of GDDR6 memory running over a 192-bit bus interface. The memory stick speeds will be configured to 12 Gbps, which will give a total bandwidth of 288 GB / s. GeForce RTX 3060 6 GB has TGPs of 60W and up to 130W.
According to NVIDIA itself, the RTX 3060 laptops start at $ 999 US and will provide 30% better performance than Sony’s PS5 console. It seems that NVIDIA is targeting the laptop as a 1080p 90 FPS gaming solution.
