1070 Max-Q better card than 1080 Max-Q for many reasons.
Here are some facts.
1060 Max-Q is 11% slower than 1060 Mobile but 53% faster than 1050ti Mobile.
1070 Max-Q is 18% slower than 1070 Mobile but 25% faster than 1060 Mobile.
1080 Max-Q is 12% slower than 1080 Mobile but 0% faster than 1070 Mobile.
1080 Max-Q is only GPU that is not faster than its lower tier mobile GPU.
1080 Max-Q is 18% faster than 1070 Max-Q
1070 Max-Q is 52% faster than 1060 Max-Q
1070 Max-Q has much higher performance jump from its lower tier Max-Q card.
Based on Asus Zephyrus GX501VI and GX501VS reviews,
1080 Max-Q temperature goes up to 80°C on load, whereas
1070 Max-Q temperature goes up to 70°C on load.
In which it gives 1070 Max-Q a headroom to overclock, reducing performance difference with 1070 mobile and 1080 Max-Q, while
1080 Max-Q will throttle if overclocked.
To conclude
Due to the nature of 1080's high TGP, Max-Q version of 1080 has worst efficiency, performing much like a 1070 card.
1070 Max-Q a smarter choice for the Max-Q Laptop for its performance efficiency and better acoustic. [Jan '18nday76]
Nvidia’s RTX 2060 Super GPU is a refreshed version of their RTX 2060 launched just 10 months prior. With this iteration, NVIDIA are hoping to contest AMD’s recent RX 5700 and RX 5700 XT with a better value proposition than compared to the 2060. The RTX 2060 Super uses the same GPU die as in the 2060, but has extra CUDA cores (increasing from 1920 to 2176) and 8 GB of GDDR6 memory (up from 6 GB), capable of delivering 448 GB/s of memory bandwidth. It has a has a TDP of 175 W, compared to 160 W in the 2060. The RTX 2060S also features Turing NVENC which is far more efficient than CPU encoding and alleviates the need for casual streamers to use a dedicated stream PC. The 15-20% increase in effective speed from the 2060 to 2060 Super costs around $50 on reference price tags. For now Nvidia will retain the "not-Super" RTX 2060 as the most affordable GPU in the ray-tracing 2000 series at $350 USD. [Jul '19GPUPro]
