ASIC architectures?

[kingcoin]

Are the architectures of some of the current ASIC offerings described anywhere?

• How many SHA256 cores do they typically have per die?
• At what frequency or throughput do the cores operate?
• What kind of external interface do they have?
• What kind of chip to chip interconnect do they have?

Briefly, without looking it up I can tell you for BFL:

16 engines/chip, just under 500MHz, USB only. No idea about interconnect.
