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]
The RX 6900-XT assumes the flagship position in AMD’s latest RX 6000 series of GPUs which deliver a huge generational jump in performance. The $1,000 USD 6900-XT offers a small improvement (11% more compute units) over the already launched $650 USD RX 6800-XT. AMD have upgraded the single fan cooler to a more efficient triple fan solution, perhaps indicating a shift in focus from benchmark busting headlines to user experience. Following the widespread issues that users faced with the 5000 and Vega series, we are cautiously optimistic that AMD have taken steps to ensure driver and hardware stability. Given the value for money now offered by both Nvidia and AMD, with the 3070 and 6800-XT, it is difficult to recommend any thousand dollar graphics cards to most gamers. 16GB of VRAM is a key feature of the 6900-XT. At higher resolutions and detail settings, performance can bottleneck without sufficient GPU memory. AMD's marketers often cherry pick obscure games with high res/settings, the details of which are rarely disclosed, then compare the results with cards that have less memory. In that scenario, the cards with less memory look weaker than they would at 1080p. The 1080p results are sometimes omitted, or worse, partially omitted and frame drops are conveniently ignored. Most users will see little benefit in gaming at high resolutions. Without drastic price cuts (MSRP $1000 USD) and miraculous marketing via countless promo videos and sponsored reviews, the 6900 XT will struggle to compete, partly because it lacks RTX+DLSS which is required for the best gaming experience in class leading titles such as Cyberpunk 2077. Users should be wary of AMD’s army of social media accounts, they aim to dupe shoppers any way they can. [Dec '20GPUPro]
