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 Radeon RX Vega 56 is the weakest member of AMD's Vega GPU family. The Vega architecture is built on 14 nm silicon and contains next-generation compute units (nCUs). Each NCU houses 64 steam processors, of which the Vega 56 has 3584 vs. 4096 in the Vega 64. The new architecture employs 8GB of second generation high-bandwidth memory (HBM2). In terms of compatibility all of the games we tested were fine apart from GTAV where enabling reflection MSAA resulted in very poor, almost matt, reflection fidelity (the same bug appeared on several Navi and Vega cards). Although the Vega 56 has 12.5% less processing units, users have found that by flashing an RX 64 BIOS into an RX 56 card allows a 10% increase in OC headroom which effectively brings a BIOS flashed RX 56 onto par with a stock RX 64 and just 12.5% slower than a fully overclocked RX 64. All of this OC headroom is great on paper but in the real world the reference Vega 56 is far too noisy. Hair dryer levels of noise at stock clocks are unacceptable for most users. Provided you are partially deaf or happy to use noise canceling headphones the Vega 56 “can” deliver levels of performance that approach an RTX 2060 but prices need to drop below $200 before the Vega 56 is competitive.
