AMD Radeon VII (gfx906) Delivers ~90 MHS Ethash Out of the Box

7 Feb
2019

The new AMD Radeon VII (gfx906) GPUs are about to start hitting the market any moment now with a recommended end user price of $699 USD in USA or 739 EURO in EU. We just got a tip that these new 7nm GPUs from AMD with 16GB HBM2 video memory are able to deliver about 90 MHS for Ehereum’s Ethash algorithm out of the box without any overclock. This is possible with the latest Claymore Dual GPU Miner v12.0, so really out of the box performance very close to the 90 MHS mark for Ethereum. So the new HBM2 memory with 4096-bit memory bus and 1000 MHz (effective 2000 MHz memory clock) seem to be doing quite well for memory intensive crypto algorithms.

We are of course still about to see what the performance for GPU intensive algorithms is going to be and this might also need some specific optimizations for the new GPUs in order to get the maximum performance. With the presence of 3840 stream processors the new Radeon VII GPUs should have plenty of raw power available for GPU-heavy lifting including, but not limited to crypto hashing. We are quite pleased to see the good memory performance for Ethash and expect good results for other algorithms as well, so hopefully very soon more performance data for crypto mining for the new AMD Radeon VII will surface…

Great, i will be getting 2 pieces tomorrow. How power hungry it is while mining those 90?

Out of the box settings, so a lot (Radeon VII can be quite power hungry), but you should be able to lower the power consumption for non-GPU intensive use cases like Ethereum mining.

It has similar characteristics to older Vega’s so that means AMD was overly generous on power. So.. undervolt accordingly. That’s also a stock run, yeah? Imagine once you bump the mem to 1200.. which some have said it easily hits..

As a side note.. it uses slightly less power and runs slightly cooler than the 64.. so in theory you should be able to get it down power wise to just below what your running 56s/64s at.

For CryptoNight V8 the hashrate is about 2700-2800 H/s at the moment at stock settings, though it could probably get better with further optimizations.

Its capable of 125 Mh/s theoretical and can easily hit 112.5 Mh/s (90%) with software optimizations, even more if you’re good.
