I'm surprised that BFL didn't get better efficiency than they did. Just going from 90nm to 65nm should double efficiency, right? Then where's the additional advantage of using the full custom approach? I'm comparing with the current power estimate of the bASIC.

It's not just the fabrication process size that matters. The implementation of the hardware is a huge factor.

The 1w/gh is a conservative estimate.  They are expecting lower power usage than that.

I wouldn't call +/- 10% a conservative estimate.

Can someone from BFL please clarify if at this moment their ASICs are packaged and delivered to the US?
"Josh Zerlan, a BFL representative, expects to have chips in hand by the end of November and begin initial shipments shortly after."
http://bitcoinmagazine.net/bfl-confirms-65nm-process-for-sc-lineup/

And we finally have confirmed that BFL is the winner in the process size category. 65nm sounds pretty sweet to me.
Once process sizes are confirmed, it will be interesting to compare actual efficiencies (J/Hash) - to me, the winner will be the one who used best and smartest engineering to get the most bang for the buck.  This should also translate into highest profitability for the manufacturer, assuming everyone offers similar price per Hash/s.

Looking super cool.. is this a custom heatsink build for them?

That is unlikely.

First of all, the label on the heat sink says "Please remove label before you use it." This is bad English... I am assuming they are made in china.

Heat sinks come in so many different shapes and sizes, it doesn't make sense to me for them to spend the extra dough to create a custom heat sink.

I can see why they say that heat will no longer be an issue for these.

There better not be a heat issue when they've got those sexy heatsinks on the boards Tongue
Depends on how level the 8 chips are ...

The label backing seems a bit OTT, though.

Underestimating customer stupidity is a common mistake. They've apparently learned their lesson already.

Back in the days of s.478 a friend of mine installed the cooling with the plastic cover without even notice it. I spend some time looking for the problem why a new PC is shutdown before I can get to BIOS

Just remember to peel off the label before you stick it to something.

I love this. Take a look at the current Single's heatsink:



It was later upgraded to this heatsink setup:



Those dinky little heatsinks were originally only supposed to dissipate 20 Watts, but had to be upgraded to handle the actual heat output of 80 Watts. Now, they're actually designing a proper heatsink for the 60Watts they know the Single will draw. Pics from http://bitcoinmagazine.net/bfl-confirms-65nm-process-for-sc-lineup/ :

Read the thread, they were.

Wasn't it decided that these pics, while exciting, were still not of a functional unit as they are waiting on the asic chips?
Yes, still not functional, cases/side skirts and asic chips are not delivered yet, boards not produced.

That's simply impossible, for the FCC has one and BFL should be getting approval in a couple weeks. Make that two, for UnderwriterLabs (UL) has one also so that it'll be UL Listed/Approval. Now quit spreading FUD. The same process will apply for the other rigs as well, up to and including the $29K one.

Image the conversation at UL when that big ass rig arrives.

UL Guy 1: What the heck do we have here?
UL Guy 2: Never seen anything like it. Ready to plug it in?
UL Guy 1: I'm not pluggin' it in. You plug it in.
UL Guy 2: Fuck you, man! Hey! I got an idea. Let's get Mikey.
UL Guy 1: Yea, Mikey! He'll plug in anything.
UL Guy 1 & UL Guy 2 (in unison): Hey, Mikey!
UL Guy 2: Wait a second! We don't have to plug it in.
UL Guy 1: Why not?
UL Guy 2: Don't you see? It don't have an FCC sticker, so we don't have to inspect it.
UL Guy 1: Great! Send it back to the girls over at Butterfly Labs.
UL Guy 2: What I would give to watch one of their hot babes on the assembly line.


My mistake. I thought they had boards/samples, but were still waiting on the chips. Oops.
