NotebookCheck published preliminary benchmark results of some gaming laptops that use NVIDIA's new Ampere-based GeForce RTX 30 series GPUs. The conclusion is that the new mobile parts are about 7 to 18 percent faster than the Turing generation in 3DMark tests -- which means they're a lot slower than the desktop variants:
3DMark Time Spy GPU test shows the RTX 3080 Mobile having a lead of 17% over the average RTX 2080 Super Mobile and about 14% faster than the RTX 3070 Mobile. We see that the RTX 3080 Mobile is a significant 31% slower than its desktop variant. The RTX 3070 Mobile is about 3% faster than the RTX 2080 Super Mobile in this test.

Coming to 3DMark Fire Strike Standard GPU, the RTX 3080 Mobile is behind both average values of the desktop variants of RTX 3070 and RTX 3080 by 13% and 31%, respectively. The RTX 3060 Mobile trails the average RTX 2080 Super Mobile by about 10% but is also 4% faster than a desktop RTX 2060 Super.
One of the reasons for this is that the mobile Ampere cards have a lot less CUDA cores versus the desktop parts.
