First, take a look on Nvidia specified TGP values for 16/20 mobile GPUs in their website:
GTX1650: 30-50W
GTX1650Ti: 35-55W
GTX1660Ti: 60-80W
RTX2060: 65-90W (65-115W in the latest update)
RTX2070: 80-115W
RTX2070S: 80-115W
RTX2080: 80-150+W
RTX2080S: 80-150+W
To simplify things, here is the possible TGP values you can find:
GTX1650 MQ: 30W
GTX1650: 50W
GTX1650Ti MQ: 35W
GTX1650Ti: 55W
RTX2060 MQ: 65W
RTX2060: 80W, 90W, 115W
RTX2070 MQ: 80W, 90W, 100W, 115W
RTX2070: 115W
RTX2080MQ: 80W, 90W, 100W, 150W
RTX2080: 150W-200W, some use 150W, some use 180W, some use 200W
(will update 2070S and 2080S when reviews are out)
So what do these values mean? Why I wanted to bring up this topic? Basically, higher TGP means the GPU is able to operate at higher clock speed (assuming same GPU). Eg 1500MHz average compared to 1400MHz average. In general, the same GPU can have different performance depending on the TGP. You might get 115W 2060 in Laptop A and 80W 2060 in Laptop B, and the 115W 2060 will surely perform noticeably better (considering things like thermals, specs are similar).
The variation in TGP causes a lot of confusion even for laptop enthusiasts, let alone normal consumers (most of the buyers). Most people will think that every 2060 GPU is the same in every models, but in fact it isn't. There isn't a way to figure out what TGP is set in a particular model since most product pages won't tell you the TGP, unless someone actually test that (even some laptop reviews won't test that). This situation is more common in Max-Q laptops. Worse still, some manufacturers don't even specify that they are using Max-Q GPUs in some laptops. For instance, Thinkpad X1 Extreme Gen 2 is advertised to have GTX1650, but in fact it's a 1650MQ.
I would advise people to check which GPU variant they are getting; however, how many buyers will actually check that? I bet it would be less than 1%. Consumers should have never do the checking at the first place, in my opinion.

Agreed with the article . It will create confusion among technical teams as well as sales.
ReplyDeleteas it has many hidden specs that many do not know.
