What is more important? Low equipment cost or low power?

Hi Everyone.

I have a question, and I’d really love to get the opinion of ZCash miners. XTend Online is producing a new generation of PCI card to completely replace GPUs for mining by late 2019. GPUs can never compete with ASICs primarily because they are optimized for graphics, not mining.

We are 2 Silicon Valley veterans making fully programmable equipment for the community. 10x faster than today’s GPUs for mining, just as programmable and at a relatively similar price points to today’s high end graphics cards. They will be able to compete head on with ASICs. Importantly, we come from the West and have a strong belief in equal access and fair treatment for everyone, not just for our friends. We firmly believe in the philosophy of blockchain. Large organizations, be they governments or private companies, have created an economy run by sociopaths, and we are committed to supporting the ideals of decentralization. This product is born of that vision.

That said, we currently have a decision to make on our product, and I would like to know the ZCash community’s thoughts on which direction we should go. Assume we have a hypothetical PCI card that is a plug in replacement for GPUs and is delivering around 50k sols/s for 200,9 and about 4000 sols/s for 144,5 and 192,7. One choice we have is to use a cheaper silicon technology process, but that will require about 33% more power to operate. Another option, is to use a more expensive silicon process that will cost about 25% more but operate at lower power.

For this analysis you can assume an acquisition price of around $2K for the cheap option and about 600 watts for the low power option.

Which variant is more attractive to the community here?

1, Faster ROI 
2. Lower power (33% less electricity for the same hashrate)

If you have a moment to spare to let us know your thoughts we would appreciate it. We would like to produce something that has maximum benefit to the community. It is easy to ask the opinion of large mining farms, but very hard to get feedback from smaller miners. Since this is a product we intend for everyone, we’d like to understand everyone’s preference.

Have a great 2019.


For me, faster ROI - specialised gear doesn’t have much resale value & as difficulty trends up there’s a small window to make a profit. Longevity isnt a factor, I crank it up until you can make toast on it.

GPU resale value changes the equation, mine while profitable then sell the gear & buy coin when things change.

Just my humble opinion - I’m sure you’ll get a lot more info when @boxalex sees your post :wink:

I would recommend producing both and let the market decide. You will see different miners choose different options largely based on thier individual electrical costs.

You can’t accurately predict a “fast ROI” because you can’t accurately predict a coins difficulty changes.

If you really have a legitimate product offering I highly recommend giving YouTubers like VoskCoin your product for a review.

Important note: The cryptocurrency space is full of “super awesome mining hardware!” scams. Buyers should beware of promises that are too good to be true

Xtend Online is a Cryptocurrency ICO offering for mining hardware which may or may not actually exist. User Xtend_Online conveniently neglected to mention this fact in thier first post in the forum.

Thereby this post is likely to be a advertisement for thier ICO and is in Violation of the Zcash Community Forum Community Guidelines.
