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]
AMD’s mid-range RX 590 is the latest refresh of their Polaris-based RX 580, which in turn was a refresh of the RX 480. This iteration yields 10% higher clock speeds compared to the RX 580 which is fuelled by an increased power draw from 185W to 225W. The 590 does not have a 4GB variant which is good for longevity. At launch the 590 was priced at $280, which was 20% more expensive and 7% faster than Nvidia’s then popular 6GB 1060. In today’s market the 590 can be found for little as $170. For more than 90% of gamers (≤1080p) the RX 590 (at $170) represents the best value for money available. Since the GPU is by far the most important component in a gaming PC, it is usually worth spending more on it. The next step up from a 590 would be to Nvidia’s comparable $230 1660S. The 1660S is a more refined card, less heat results in less fan noise, but both are capable of delivering silky smooth 60+ EFps in almost all of today’s popular games at 1080p with maximum details.
