AMAZING COMPANY!
No, d00d, I do. Don't bullshit people if you don't like being called on it. Or, at least, get better at bullshitting.
Oh if you insist...
#1 indication of cluelessness: Doesn't realise there's a difference between the process size of the chip and the positioning of chips on the boards. "Derp, joo can't place duh 28nm chips like der 130nm chips because dose are obsolescent"
#2 indication of cluelessness: Doesn't realise there's a difference between the thermal problems of a ~200W chip and a ~400W chip "Derp, KNC can use a air cooled heatsink on a ~200W Chip so doing it with der 400W must be real easy too"
#3 indication of cluelessness: Doesn't realise that heat will have to be distributed and spread 3 dimensionally out of a 2 dimensional area, and the difference between 1 square inch and 4 half inch squares is that they basically lose half their conduction path each when butted together. "Derp, that should oughta be okay, I mount my CPU sinks with der CPU right in one corner because dey work just as well like dat"
Stop fighting strawmen, and address what I have actually said.
I gave you line numbers to make it easier. If you disagree with any of my points, feel free to refute them.
#1. Boards like Avalon clones are already at the edge of obsolescence.
#2. KnC has no trouble with conventional, "cheap, simple, reliable and well characterized thermal solutions," lol.
#3. While water cooling might have been bleeding edge in the 90s, it's consumer-level commonplace today.
#4. Ken never built any miners, including Avalon clones. The fact that he was *going* to build them gives him exactly zero experience with any design, obsolescent or otherwise.
#5. It pays to know the basics about your subject before bringing up "watts per meter" and brandishing absurdities like "100W out of four half inch squares."
In the meantime, I'll explain where you went wrong with your list:
#1 - I have not mentioned node size. I pointed out that the current trend is high GH/sec, high power ASICS. By at least an order of magnitude more powerful than Ken's (if Ken actually *had* chips, which he doesn't). KnC first generation, soon to be outmoded by their second generation. HashFast. Cointerra. BFL.
#2. - 400W chips are not "contiguous squares," that's silly. They are a set of dies set on a single substrate. KNC. HashFast. Please, read up on this, or, at least, look at the pictures. I'll put them right here:
HashFast, see the four dies?
KNC and no, it's not one die under that lid
#3. See above, and forget about 3D - you're confused. The wafer doesn't dissipate much heat through its edges, that's why they're called "wafers" and not, oh.. "blocks." Most of the heat is dissipated through just *one* of the surfaces, the one the heatsink sits on.
Keep trying though.
