GPU_Hoarder has his CN7 (19.7-22KH/s = 10-12x Vega 64) algorithm running on an unmodified VCU1525.

Bitstreams+miner or it didn't happen. :-)

The only thing that has been demonstrated thus far is that buying a VCU1525 for mining Keccak is a not a sane proposition vs. getting a 1080Ti for mining ethash.
I am still very hopeful that other algorithms such as CN7 will make this into a much more worthwhile endeavour.

Most importantly, however, I think the profitability measurement should be based on what can be achieved with an unmodified FPGA at 30C ambient temperature, rather than based on optimistic measurements with modifications that involve replacing PCB components.

- does anyone determine profitability including power for GPUs without any mods? The % you achieve without mods is about the same here.

First - Absolutely no one was suggesting you buy these to mine Keccak. Those who understand and take the time to read will profit, those who dont wont. Simple as that. Whitefire is providing a great service to the community in exposing all this publically - it has been working in private for a long time. He only stands to lose money sharing, yet he is sharing. I applaud that alone.

Second - You do realize no one has any incentive to provide you this bitstream and they have every incentive to keep it private, right? Also wasnt developed for the VCU1525, just the same chip, so some modification is always needed.

At a certain point in life bragging rights have no value.

The people who do this understand the value of the Keccak test. It proves numerous things on this card - hardware limitations, power and thermals, achievable fabric speed at logic level, and performance of components. Take a look at the Keccak speeds on little baby precious classes of mining FPGAs. 100MH. Sometimes less.

FPGAs are not GPUs. Repeat that a few dozen times. The complexity of a best in class implementation on a large, complicated FPGA like this is very large. So are the gains when it is done right. So is the difference between the trivial implementation and the efficient implementation.

I can say that all this functionality will be available in the cards come delivery in August. With proper protections. If the community has any say Im sure open bitstreams will exist before then, we will see if they achieve the marks.

The open source implementation of Keccak are quite poor and see no where near this performance, and FPGAs operate < 1Ghz, where the graph slope is much narrower. Youre missing that this is more than 25x performance of a GPU in Keccak for 10x cost of that GPU. Keccak may not be profitable now on either (hint - it was very very recently), but the principle applies across the algorithm space.
