[londons_explore]: Whilst processing in memory is clearly the future, I am unconvinced by this implementation. Matrix multiplication involves getting every entry of the input and output matrices to be at the same multiplier at the same time. (Ie. N^2). To do that, a lot of data movement needs to happen. Movement is the main thing - the multiplication and addition is a sideshow as far as energy and silicon space is concerned. You need a 'around the chip' ring shift register to pass every element ...
[pragma_x]: What I find amusing about moving compute to a RAM bank is it _almost_ resembles where we were with ISA-based extended RAM back in the 1980's. Some cards featured a CPU that took over the whole system and/or functioned like an upgrade. Others were a "computer on a card" that provided other features. I think this goes to show how cyclic tech can be. So, something like Samsung's invention here might have gained traction, as overcoming the slow PC ISA bus would have b...
[plywoodShadow]: What about energy consumption? Wouldn't active cooling be needed for RAM as well as for CPU and GPU?
