Power configurations for NVIDIA GeForce RTX 30 Mobility GPUs that include the GeForce RTX 3080, RTX 3070, and RTX 3060 have been detailed. NVIDIA GeForce RTX 30 series will launch in Max-Q and Max-P versions, with different configurations of core, clocks and memory.
Leaked NVIDIA GeForce RTX 30, GeForce RTX 3080 Mobility GPU power configurations up to 165W for hobby notebooks
There are three power profiles in which NVIDIA GeForce RTX 30 Mobility GPUs will operate. These include Base TGP (Total Graphics Power), cTGP (Configurable Total Graphics Power), and PPAB which is an AI-accelerated dynamic boost range. PPAB will be primarily optimized by OEM laptop manufacturers for their cooling capacity based solutions.
For Max-P variants, PPAB would provide 15 watts of extra power to the GPU, while in Max-Q variants this will be rated up to 20 watts. The reason the Max-Q variants offer a higher PPAB range is that they feature a lower TGP, to begin with, while the Max-P variants come with higher minimum TGP.
There is now a report from NotebookCheck that NVIDIA has removed the Max-Q and Max-P labels from their GPUs and that OEMs are free to decide which TGPs they want to set for their laptops running GeForce RTX 30 Mobility GPUs. . This means that the minimum TGP should therefore be intact, but other metrics such as cTGP and PPAB ranges will depend entirely on what OEMs plan to do with them.
NVIDIA GeForce RTX 3080 16 GB Mobility GPU – Laptops From $ 1,999
The NVIDIA GeForce RTX 3080 graphics card will be the flagship offering in the NVIDIA RTX 30 family of notebook GPUs. The NVIDIA GeForce RTX 3080 Mobility will feature 48 SM on the GA104 (GA104-775) GPU SKU. This chip would feature a total of 6144 cores, a base clock of 1245 MHz and a boost clock of 1710 MHz.
The graphics card also has 16GB of VRAM that runs on a 256-bit bus interface, but it remains to be seen whether NVIDIA uses 12 or 14 Gbps DRAM modules for its mobility range. In the case of 14 Gbps, the GPU will be able to offer a maximum bandwidth of 448 Gbps.
The Max-Q variant of the GeForce RTX 3080 Mobility GPU will feature a starting 80W TGP which will be configurable up to 165W. GeForce RTX 3080 laptops will start priced at US $ 1,999 and deliver over 100 FPS at 1440p resolution in multiple game titles.
NVIDIA GeForce RTX 3070 8GB Mobility GPU – Laptops From $ 1,299
The NVIDIA GeForce RTX 3070 Mobility will feature 40 SM on the GA104 GPU SKU (presumably the GA104-770). This chip would feature a total of 5120 cores, a base clock of 1290 MHz and an increase of up to 1620 MHz. The graphics card also has 8GB of VRAM that runs on a 256-bit bus interface, but it remains to be seen whether NVIDIA uses 12 or 14 Gbps DRAM modules for its mobility range. In the case of 14 Gbps, the GPU will be able to offer a maximum bandwidth of 448 Gbps.
The TGPs for the GeForce RTX 3070 will also have a base TGP of 80W but can only be configured up to 150W. The GeForce RTX 3070 laptops will start at US $ 1299 and offer 90 FPS 1440p gaming.
NVIDIA GeForce RTX 3060 6GB Mobility GPU – Laptops from $ 999
Finally, we have the GeForce RTX 3060 6GB which was also announced for the desktop segment today but with 12GB of GDDR6 memory. The desktop and mobility variants feature the GA106 GPU, but the laptop variant comes with 30 SM units enabled, for a total of 3,840 CUDA cores. The graphics chip will feature clocks starting at a base of 1283 MHz and going up to 1703 MHz in boost frequencies.
As mentioned earlier, the GeForce RTX 3060 6GB graphics card will ship with a total of 6GB of GDDR6 memory running on a 192-bit bus interface. The memory pin speeds should be configured at 12 Gbps, which should result in a total bandwidth of 288 Gbps. The GeForce RTX 3060 6 GB will feature TGPs of 60W and up to 130W.
According to NVIDIA themselves, the RTX 3060 laptops will start at US $ 999 and offer 30% better performance than Sony’s PS5 console. It looks like NVIDIA is targeting the laptop as a 1080p 90 FPS gaming solution.
