yeah, the die's $600 while everything else (memory, vrms, pcbs, capacitors) is free.
good maths.
Why did you quote only half of my post? You literally missed my point, which was that the 4070 should be more expensive just from the die cost increase, ignoring all the other components of a graphics card.
The PCB is basically identical to the 3070's. The main difference is two fewer memory chips, albeit faster. But the "inflation" affects all these components too, so it's literally unreasonable to call the 4070 overpriced, unless you consider the 3070 overpriced. And it may have been more so, considering how good a deal NVIDIA got from Samsung.
The math definitely didn't check out with the 4080 compared to the 3080. Considering just the die size difference, you get $700 x 0.6 x 1.6 = $672. But somehow they priced that card at $1200, even though the PCB is simpler and the TDP is the same. This is the definition of overpriced.
4070 is 20% more expensive and 30% faster than the 3070.
4080 is 71% more expensive and 50% faster than the 3080.
I think these numbers speak for themselves.
Also, the 4080 is 50% faster than the 4070 at double the price.
