I'm picking a SDRAM IC for a custom embedded board and was surprised by the low prices. Was expecting orders of magnitude similar to PC ram of the same capacity.
For example H5TC8G63AMR-PBA chip costs almost 4 times less than this Corsair Vengeance 8GB (1x8GB) DDR3 1600 MHz (PC3 12800).
Digging into the datasheet [page 4] for the RAM on chip it states that it its configuration is 512M x 16 and the speed isn't clear from the name.
- Is the speed the main reason for the difference?
- Are there other factors (like a need for a PCB) that multiply the price?
