The original plan regarding Ada was $600/$900/$1200/$1600 for RTX4070/4080 12GB/4080 16GB /4090 and this kinda shows Nvidia's way of thinking and intentions. Because the raster performance jump for Blackwell will be underwhelming and based on what I expect regarding performance for Blackwell lineup I thought that the pricing will be $600/$900/$1100/$1700 for RTX 5070/5070Ti/5080/5090 but now that I think about it again it should be probably $600/$900/$1200/$1800.
RTX 5070 should stay at the same price since the raster performance increase should be 10% or something around this level, RTX 5070Ti should be finally at $900 (original intention of Nvidia was to name RTX 4070Ti , RTX 4080 12GB and price it at $900, this time 5070Ti will have the same memory size as it 5080 and also it will be based on the same chip instead of a lower tier like it was in 4080/4070Ti case, so I think Nvidia will try again to force the $900 price tag).
RTX 5080 should have $300 difference from RTX 5070Ti, I don't think the gap will be smaller than the gap between RTX 5070 ($600) / RTX 5070Ti ($900) and finally regarding RTX 5090 since demand for RTX 4090 was not affected after the launch of 4080 Super at $1000 it should maintain the $600 gap from RTX 5080, so it should be $1800 (also 2X the price of RTX 5070Ti, like it was in RTX4090 $1600/4070Ti $800 case).
Regarding high-end the cost for RTX 5090 will be higher for Nvidia in relation with RTX 4090, the process is similar with mild difference, AD102 4N (5nm based) 609 mm² vs GB202 rumored at 744mm² in a process based on 4nm, the memory bus also is 512bit vs 384bit with 32GB vs 24GB memory and the ICs are GDDR7 based instead of GDDR6X, the interface is gen5 instead of gen4, the power consumption is higher and these changes affect also other factors potentially like PCB layers and other components so the $200 increase seems logical to me to happen in this case, regarding the others prices are a major letdown also (except maybe RTX 5070 which is just meh)
