Oh, also, to be clear, it's not 16 image engines _total_. It's 16 image engines _per fragment generator_, so at least 80 of them in total, "and enough framebuffer memory to allocate 256 bits per pixel to a 1280x1024 framebuffer". "Most floating point arithmetic is done in single precision, but much of the texture arithmetic, and all depth arithmetic after projection transformation, must be done in double precision to maintain the required accuracy."
