Re: Official: Sony Alpha a1 Mirrorless Digital Camera
that makes sense, it's basically two a9 sensors packed into the same space
i'm guessing that it's also different in that the 2017-era a9/a9ii sensor used ddr3, so it's a safe bet that the stacked ram in this sensor is quicker than that.
faster memory loads/unloads the data in less time, which is going to give the bionz xr chips more time to process the data... the fact that there is flash capability with the electronic shutter would indicate that as well, it's a huge accomplishment.
then there are improvements to the interconnects between the stack layers, which was perfected with the smartphone sensors... rb alluded to that in the link: "In addition to the DRAM built into the back of the sensor to cope with all the data being produced, Sony says the new 50MP sensor features a 'high speed processing circuit with new analogue-to-digital method' between the photodiodes and the DRAM at the back of the chip. Sadly they would not give any more details about this 'secret' technology."
