next usb miner coming yay
yeah if a 5gh bitfury chip hashes at 2.6gh in an ice fury or red fury these should hash at 5gh-6gh
Out of curiosity - what makes you think that the bitfury chip should hash at 5-6GH?
First post in bitfury thread
https://bitcointalk.org/index.php?topic=228677.0Preliminary specs - each chip would give roughly 5 GH/s performance.
The post you're referring to was made while they were waiting for the first chips from the fab and actually didn't know for sure how were they going to perform.
This is what Bitfury said about the design of the chip:
Finally die dimensions chosen: 3.8x3.8mm
Package: QFN48
Performance: 3.3 GH/s _rated performance_, about 7 GH/s maximum
Power consumption: 1 W at _rated_ performance @ 0.6 V, 6 W _maximum_ performance @ 1.0 V.
Thermal characteristics of package: 2 K / W junction-to-pcb and 34 K / W junction-to-ambient.
and I'll have to look for the other post where he said that there was a bug on the die and because of that they couldn't get the double performance (7GH).
Also, there are very few people that have actually achieved even the 3.3GH as that requires very very precise conditions, and even reaching 3GH is quite a challenge. Most chips perform fine and start hitting the limits in the 2.5-2.7GH range.
I just wanted to set the record straight so that people don't have the wrong expectations.
