Apart from its not 3080 performance, it has more vram, dlss3 and uses much less power, which means its cost over a life time is much less, https://youtu.be/uZHDq-LEGzw?t=1238He wanted 3080 performance when the 3080 cane out. Why would anyone accept 3080 performance for £600 now, 2 years later?
When Nvidia/AMD move to a new better node process they can decide how much of that node they use to boost performance & how much is to reduce power. It presents from this thread that most people would have wanted more of a performance boost and less of a reduction in power usage, however, for me I am pleased to see such a big reduction in power usage.
It could be argued that the 4070 as designed would suit miners better than gamers because of the increase in power efficiency, but that is another argument. However, reducing power consumption over millions of gpus going forward is better for the planet at this current time when we are not carbon neutral.
e.g
5nm
TSMC 5nm Node uses EUV and improves logic density by 1.8x compared to 7nm. For SRAM, the density is 1.3x higher. Just like the 7nm Node, 5nm will have two variants with one optimized for Mobile and other for HPC. The mobile node will allow 15% higher performance or 30% lower power consumption. The HPC variant will instead offer 25% higher performance over 7nm.Apple’s A14 Chip in 2020 will likely utilize the 5nm Mobile Node while AMD’s Zen 4 could utilize the 5nm HPC node in 2021.
