The infamy of the desktop 4060 Ti got me curious about how the mobile 4070 fares in a similar comparison, since they're fundamentally the same chip...and it's just as bad.
Compared to the 3070 Ti, the 4070 is overall heavily cut down, from memory bandwidth to pipelines to even raytracing and tensor cores. Without accounting for architectural differences, AD106 is basically only 75% the chip GA104 was. The only improvement is a ~50% increase in clocks, as a result it's hardly any faster (~10% overall, and ironically, 0.75x1.5=1.125), questionable if any more efficient on a high load(same max TGP given the performance noted), and understandably they refuse to disclose transistor count, since it's no doubt a heavy regression. And they ask for the same if not a higher price.
At the same width, TSMC 4N should be massively more efficient than Samsung 8N, about 2 full nodes' advantage, yet they use nearly the whole of the process advantage to cut down the chip to boost their own margins, instead of actually bringing improvement to the product, releasing this feeble upgrade 2 years after 3070 Ti. The corresponding YoY gain is approaching Intel's 14nm+++++, an industry laugh forever cemented in history.
They're milking the blood out of this cow, purely out of choice, which is to say ill will. Evil. Ngreedia is truly evil.
