Mobile NVIDIA GeForce RTX GPUs Will Vary Wildly in Performance, Clocks Lowered Substantially
NVIDIA is in the process of rolling out the first implementations of its RTX 2000 series GPUs in mobile form, and if the going is as is being reported, it's going to be a little rough for users to actually extrapolate their performance from product to product. This is because manufacturers are apparently getting a whole lot of leeway in how to clock their products, according to their solution's thermal characteristics and design philosophy.
What this means is that NVIDIA's RTX 2080 Max-Q, for example, can be clocked as low as 735 MHz, which is a more than 50% downclock from its desktop counterpart (1,515 MHz). The non-Max-Q implementation of NVIDIA's RTX 2080, for now, seems to be clocked at around 1,380 MHz, which is still a close to 200 Mhz downclock. Of course, these lowered clocks are absolutely normal - and necessary - for these products, particularly on a huge chip such as the one powering the RTX 2080. The problem arises when manufacturers don't disclose clockspeeds of the GPU in their particular implementation - a user might buy, say, an MSI laptop and an ASUS one with the exact same apparent configuration, but GPUs operating at very different clockspeeds, with very different levels of performance. Users should do their due research when it comes to the point of choosing what mobile solution sporting one of these NVIDIA GPUs they should choose.

Lotta heat in these cards.

They should be spaced far enough apart not to run across each other but the ranges are indeed unbelievably wide.
RTX 2080 MaxQ: base 735, boost 1095, tdp 80W
RTX 2080(Mobile): base 1380, boost 1590, tdp 150W
RTX 2070 MaxQ: base 885, boost 1185, tdp 80W
RTX 2070(Mobile) : base 1215, boost 1440, tdp 114W
RTX 2060(Mobile): base 960, boost 1200, tdp 80-90W

the bottom line being that RTX may sound good in a laptop in reality its gonna be a waste of space.. currently the desktop RTX 2060 is a waste of space.. down clocked laptop versions whatever the number will be the same..

2080 is noticeable faster at 1440p. Now you can ditch your lies that Nvidia cards are faster because higher clock speed.
Hell, I know even more magical example, Vega 56 can beat Vega 64!
Oh, and 64 even has more CUs, WTFBBQ!
Now, EAT THIS, NVIDIA HATERS!!!
Disclaimer: I would have thought user to be sarcastic, but I know this totally unbiased person is not.
It eats into if it is used... otherwise....
Do mind though RTX 2060(Laptop) is drop in placement for gtx1070 MaxQ(They have same tdp, gtx1070 has 115W tdp). So intended form factor is a bit different.
"In short, the mobile RTX 2080 and RTX 2080 Max-Q are about 15 percent and 30 percent slower than the desktop RTX 2080 according to 3DMark benchmarks. The deltas are somewhat similar to - if not just slightly wider than - the deltas between mobile GTX 1080 and GTX 1080 Max-Q to the desktop GTX 1080 by about 5 percentage points each".
So, the gap is bigger, by a small amount according to this little write up... certainly not the end of the world as some would like to convey... ;)
It is quite typical for these to drop a card level down which tends to put it in bed with last gen same tier.
Edit: "Meanwhile, users can expect the mobile RTX 2080 to perform about the same as a desktop GTX 1080 or anywhere between 15 to 35 percent over the mobile GTX 1080 depending on the resolution."
