New Gridseed 19.2 MHS Scrypt and 520 GHS SHA-256 Dual Mode ASIC Might be Coming

16 Mar


We got a tip from a reader that a new dual mining mode ASIC device based on Gridseed chips might be coming out soon. The device is supposedly capable of providing up to 19.2 MHS Scrypt and 520GHS SHA-256 is listed for with a price of $12888 USD on a Chinese online store and is being sold by a company called EastShore Trade. This is a pre-order and they claim the miner will be available “at the end of March”. The photo above of the actual miner does look Ok, though the photo itself and the claimed specifications do rise some doubts, so you should treat this information with caution for the moment!

This miner is apparently composed of 4 blades (only one blade shown on the photo or all 4 blades together?), each blade can mine at a speed of 130 GH/s for SHA-256 mining and 4.8 MH/s for Scrypt mining. So, the miner can mining at a speed of 520 GH/s for SHA256 mining and 19.2 MH/s for Scrypt mining in total. The total power consumption claimed is just 800W for the four blades and the power supply is apparently a part of the miner according to the information. The miner on the photo does remind us a lot in terms of design to the AntMiner S1 and the device apparently also comes with a LAN port, so it would be independent of a computer.

19.2 MH/s worth of Scrypt mining hashrate is achievable by using a total of 64×5 Gridchip GC3355 processors or a total of 320 chips providing 300 KHS each. With the total power usage of a non-overclocked 5-chip ASIC of about 5W we should be getting about 320W for Scrypt only mining mode if the calculation is correct. The problem comes with the SHA-256 mining part, with a 5-chip solutions needing roughly about 50W in BTC mining mode this would result in 3200W power consumption for the SHA-256 mining only or a total of 3500W without overclock for Dual Mining mode. So how come we see claimed 800W for the device, this could neither be the Scrypt only power usage, neither a single blade one (4 blades shod total in 3200W). And integrating a 3200W or 3500W power supply in a miner so small does not seem very believable (again is the photo of a single blade or of the 4 blades?). So do not be in a hurry with pre-orders at least until there is more clear information about this upcoming ASIC!

The first thing that stands out to me is that you say 3200 watts total power. So couldn’t it simply be that the Power supply is per blade rather than for the entire setup?

Looks pretty good, outside of my price range though.

Nick, it is possible that 800W is per blade and 3200W total. The fact that even the specs are still not very clear is advice to be careful with that product until there is more information about it… as the price is not in the range where you would be willing to risk it.

it’s a cheater, don’t pay him any money.
this pic comes from GS, maybe u can see that in the future, but not now, not from that guy.

I can get more hash for the price with multiple Gridseed sets.

But you need more money for accessories … power supplies, cables, hubs …

Ok. Another GS device, but what are we going to do wen the adaption to scrypt-n starts. I believe we can expect it pretty soon.
