Looks like a longer tube. How did they get the efficiency up?
Downclock and downvolt each chip.
Nope. Its a new parallel powering layout which is simply more efficient. If I get a Prisma you'll be able to see it in the pictures.
Interesting, Dogie. I assume you have some inside information. Looking at the prisma image it's pretty hard to see what's going on, almost looks intentionally blurred over the area that previously contained the buck circuits. I think it's just a low quality image, but that particular area is pretty blurry. It looks like maybe there are a couple of ICs in the area, potentially level shifters between the BEE200 chips and the AVR for SPI communication? And I am pretty sure I do see caps in between each BE200 chip, which would make sense.
