In less than two weeks, NVIDIA will present the new generation of GeForce RTX graphics cards for laptops. We expect the disclosure of details on Ampere mobile chipsets in the form of GeForce RTX 3060, GeForce RTX 3070 and GeForce RTX 3080. So far, there has been very little information on the web about the possible specification and how much the mobile Ampere will differ from its desktop counterparts. Meanwhile, today specific details about the parameters of the upcoming cards for laptops have finally got onto the network. For now, however, this is unconfirmed information, the more so as no source known to us was able to confirm or deny these reports. NVIDIA probably keeps a large part of the specification a secret, to reveal the details only at the conference, scheduled for 12 January.

According to the latest information, none of the upcoming graphics cards for laptops – GeForce RTX 3060, RTX 3070 and RTX 3080 – it will not be identical to the desktop counterpart.

If the information disclosed is confirmed in 2 weeks, the upcoming GeForce RTX generation 3000 for laptops will again introduce a lot of chaos in the naming and differences between the mobile and desktop variants of theoretically the same cards. Two of the three graphics cards are to use the Ampere GA core 104. For the flagship GeForce RTX 3080 it will be a full core from 6144 CUDA cores. This card is to appear from both 8 and 16 GB VRAM GDDR6. Despite the same name, it will therefore be a completely different system than RTX 3080 in desktop computers, where it is based on a larger Ampere GA core 102.

Specification	GeForce RTX 3060 Mobile	GeForce RTX 3070 Mobile	GeForce RTX 3080 Mobile
Graphics Core	Ampere GA 106 (GN 20 – E3)	Ampere GA 104 – 770 (GN 20 – E5)	Ampere GA 104 – 775 (GN 20 – E7)
Lithography	8 nm Samsung	8 nm Samsung	8 nm Samsung
CUDA Cores	3072	5120	6144
VRAM	6 GB GDDR6	8 GB GDDR6	8 / 16 GB GDDR6
Memory bus	192 – bit	256 – bit	256 – bit
Core clock (Boost)	900 MHz (Max-Q ) – 1700 MHz (Max-P)	1100 MHz (Max-Q) – 1620 MHz (Max-P)	1100 MHz (Max-Q) – 1700 MHz (Max-P)
TDP	60 – 70 W (Max-Q) 80 – 115 In (Max-P)	80 – 90 In (Max-Q) 115 – 125 In (Max-P)	80 – 90 (Max-Q) 115 – 150 In (Max-P)

No there will be less confusion in the case of the mobile GeForce RTX 3070, which will also differ in specification from its desktop counterpart. The mobile variant is also to be based on the GA core 104, but a bit more trimmed and equipped with a total of 5120 CUDA cores. In this case, we are also going to get 8 GB of GDDR6 VRAM. The weakest card will be GeForce RTX 3060 and in this case we will also get a card weaker than the desktop variant. According to reports, the GA core used in this case 106 will be trimmed more – the 3072 CUDA cores and 6 GB GDDR6 on 192 – bit bus. As a reminder, the desktop RTX 3060 is to appear in two versions: 3584 CUDA cores and 6 GB of memory and 3840 CUDA cores and 12 GB of memory. However, I emphasize that this is currently not confirmed (although it seems likely) information.
