$2-3k
Ding ding ding The price is stabilizing I would guess LTC will be the big winner as ASICs hit, with a price valuation extending to $200 by June

so looks like they made there 400ghash mark. You sure its only 4 dies?
lets see if the keep the 500ghs overclockable. Would be nice to have a surprise and get 500ghs out of the box and 600 overclockable
0.74 V is below 28 nm high performance specs for TSMC, which have typical voltages of 0.85 V. So if they are hitting 400 GH/s there, we should still have a lot of headroom.

Now that ASIC miners will be out for LTC in the next few months, it looks like it's time for someone to take a stab at this again so those of us with GPUs will have something to do.
I'll eat my hat if anyone ever has success with this GPU miner. By success, I mean it mines at least 1x as fast as the CPU miner, power usage wise. Eh, I wouldn't be surprised. If you can boil the problem down to a lot of integer math (and you almost always can), you can likely achieve a speedup via associated GPU use. Tacotime have you seen this: https://bitcointalk.org/index.php?topic=279194.0i have posts in that thread

Stable valuation created from dynamic and decentralized adjustment of monetary base.
this is one of the main mc2 goals, although we aren't talking about it right now (and won't really be talking about it until release).

It appears what they've done to keep the chip small is to implement 4x 256Kbit on-die memories for hashing as I haven't seen anything mentioned about an off chip memory. At 55nm 1mbit of sram is about 7.63mm2. At 28nm 1mbit of sram is 3.88mm2. The max size for QFN-48 (which is a 7x7mm package) silicon is around 4x4mm so have roughly 16mm2 of space. They couldn't have implemented 4x 1mbit as it would be to large (with an exception for the 28nm which would be 15.52mm2, but even then there wouldn't be enough room for all those bitcoin hashers). The speed and stats are certainly within the realm of possibility.
Looks like their site is up. Didn't work the first time.
55nm chip, so definitely within the realm of possibility.
That's interesting. If they did implement the SRAM on chip, I guess the could maximally fit 14 scratchpads (14 x 128 KB). If with 8 they could reach 84 KH/s at let's say a theoretical 0.750 W, we'd max out on a single chip at 147 KH/s and 1.3 W. Not too shabby if these only cost about $5-10 each to produce on 55 nm QFN-48. I'd guess they aren't using straight up scratch pads, though, but rather the TMTO desynchronization trick from Solar Designer. Regardless, the physical limitations as above should still be the same.

Scrypt requires high speed access to memory so I'm gonna say this is bull until there is some evidence it works. I'm sure someone will reverse engineer these sooner rather than later, and then we'll be looking at a lot of potential scrypt ASICs hitting the market. SEMs aren't that costly these days.

Nobody ever said there wouldn't be a scrypt ASIC, just that it probably won't be cost effective for some time.
Is that not the case here? Looks like we have a rough price for just the chip, no other supporting hardware like RAM?
Sort of. It looks like if they were to make a scrypt only ASIC, the power consumption for 330 KH/s would be about 2.5 W. This was similar to the original 130 nm ASIC miners for SHA256, but this time we're on a 55 nm process node. 130 nm should use about three fold the amount of power in theory, so scrypt is slightly less efficiency in this ASIC implementation, but not by much.

People spend dollars even though the more the hold, the more interest they gain...
Fiat devalues over time... You can invest fiat, but that's a whole different issue. Yes, proof of stake incentivizes hoarding. You could probably make a super volatile, ridiculous cryptocurrency by making it both entirely proof of stake and having the stake reward decrease over time a la bitcoin's PoW reward.

Chips and dev boards for now
Pictures confirm the release event and functionality. One person was able to get a single chip to hash at 84 KH/s.
|
|
|
So it is confirmed I guess... the second thread shows a single chip hashing at 84 KH/s.
|
|
|
Hopefully it doesn't happen soon. I want to put some more GPUs to better use.
If it happens it happens... maybe that primecoin GPU miner will finally get off the ground.

Well damn...
If it's true I'll be cranking my GPUs hard for the new few months until these come out -- ASIC introduction into Bitcoin caused a 100-fold increase in valuation, I would be surprised if we don't see a big increase with Litecoin too. This is 0.00738 W/KH/s versus 0.300 W/KH/s for a GPU -- a 40.7 fold increase in efficiency. This is about the same increase in efficiency as compared to BTC when ASICMINER first introduced its chips; I'm curious to see how they did it.

The spec sheet is here: https://github.com/gridseed/gc3355-doc/blob/master/GC3355_DataSheet.pdfThese are hybrid miners that utilize the BTC hashing core to do a few of the SHA256 calculations for LTC apparently, they are claimed to be able to simultaneously hash BTC at 1.75 GH/s and LTC at 59.6 KH/s while pulling 4.56 W. Hashing LTC alone, they are claimed to pull 59.6 KH/s at 0.44 W. the chips are not mine, this is gridchip project (team behind avalon gen1,gen2) there is conference on 8th dec in Beijing for launch where you can pick up raw chips & development board. other regions will be added later Scheduled at 10:00 on December 8, 2013, in West Street, Haidian, Beijing, 70 3W coffee (Haidian Book City, south of the membership across the sea floor), held Gridchip GC3355 chip product launches and mining machines. In addition to the chip and mine-site machine product launches, and BTC, LTC demonstration outside mining, but also on-site sales of 50 sets of single-chip development board and a few chips.
Development board: each 500 yuan chip: 400 yuan per piece, per pack of 1600 yuan four chips
This price is only preliminary offers developers, not as a formal reference to the product price. Each person can purchase two development boards, chip purchase of two packs per person. http://www.cybtc.com/thread-3226-1-1.html

Any one know more about this chip?
specs are here https://github.com/gridseed/gc3355-doc/blob/master/GC3355_DataSheet.pdfAnd holy shit, it claims to do 59.6 KH/s while using 0.44 W This is 0.00738 W/KH/s versus 0.300 W/KH/s for a GPU -- a 40.7 fold increase in efficiency. This is about the same increase in efficiency as compared to BTC when ASICMINER first introduced its chips; I'm curious to see how they did it.
