It usually takes about seven weeks after tape-out for mass production. So they may even ship in April
With the new "tape out" information that KNC has provided, it gives everyone a clearer view of what we can expect. Below is an updated idea on what I think we can expect from the Neptune.
Hash rate: 4,875GH/s
Power: 2,237W (A couple 1,200W PSUs will probably do the trick. We'll need either a 220V line or two circuits at 110v. DON'T BUY THE PSUs YET! I have no idea if my projections are even close to correct in the end!)
Here's how I figured out the above numbers.
Jupiter has 192 cores. (http://forum.kncminer.com/forum/rese...than-3000-gh-s
Jupiter needs at least 850W.
Jupiter hashes at 650GH/s for the November batch.
Neptune has 1440 cores. (https://www.kncminer.com/news/news-78
Jupiter has a 40% power reduction per core than that of Jupiter.
Using these quick facts I gathered, we can figure out Neptune's potential specs.
(Jupiter's hash / Jupiter's cores) * Neptune's cores = Neptune's GH/s
(650/192) * 1440 = 4875 GH/s
((Jupiter's hash / Jupiter's power) * Neptune's hash) - 40% reduction in power per core
((650/850) * 4875) - 40% = 2237 W
Beautiful, yes? Well I think you're really going to like this next bit. It seems like people were scared for nothing and might feel like crap now that they refunded their orders, especially because they could have sold their place in line on eBay and made ~$25,000 from it. Anyway, here goes.
Using my formulas from my thread at: http://forum.kncminer.com/forum/rese...ity-assessment
We can see the following.
7.6PH/s - KNC DC (More hash than both Neptune batches combined)
5.85PH/s - First batch Neptunes
5.85PH/s - Second batch Neptunes
Notice that the KNC DC is now going to be putting out 4.1PH/s less than both Neptune batches combined. (11.7PH/s for both Neptune batches combined)
~19.3PH/s - Total KNC hash being added by (presumably) the end of Q2.
~28PH/s - Total current BTC network hash (http://bitcoincharts.com/bitcoin/
(19.3 / 28) * 100 = ~69% (Percent of the current hash rate)
3,815,723,799 (Current difficulty) + 69% (Amount of hash being added) = 2,632,849,421 (Difficulty increase)
Now for the good part.
Let A = PH/s being added to the network
(A / 28) * 100 = B% (Percent of new hash being added)
3,815,723,799 + B% = C (Projected difficulty)
April after first batch Neptunes come online without DC: 4,617,025,797 (A = 5.85PH/s - ~15.93 BTC per 30 days)
April after first batch Neptunes come online with DC: 5,647,271,223 (A = 13.45PH/s - ~13.023 BTC per 30 days)
May after second batch Neptunes come online without DC: 5,418,327,795 (A = 11.7PH/s- ~13.575 BTC per 30 days)
May after second batch Neptunes come online with DC: 6,448,573,220 (A = 19.3PH/s- ~11.406 BTC per 30 days)

Also, remember that I have no way of accounting for how much difficulty increase will happen this month accurately and so I based things off of the current difficulty. We also don't know anything in this post to be completely true or when the Neptunes will be shipping, so this whole post might be completely wrong. In other words, don't go off of what I say alone. Do your homework and see if you find this to be accurate enough for you.

If those estimates I quoted are correct, then we should be at over 26TH/s in April/May. Which would mean ~0.20GH/s per share value.
