Suggested article: RoCM vs normal OpenCL hash rates cryptocurrencies benchmarks

[Kayote]

I said in the title I would like to see RocM vs OpenCL benchmarks of Hash rates on cryptocurrencies like ethereum or so.

[Michael]

I do have Ethereum / ethminer available via PTS. Do other cryptocurrencies have automated benchmark modes available? If so, please provide links/references and could then possibly make it a reality.

I couldn't make claymore etherminer work on RocM, it just doesn't work it doesnt detect the opencl interface. But you could do a benchmark of just ethminer compared to the most common ethereum graphics card 470/480/460 and 560/570/580 and a performance per watt/dollar. And maybe when Vega is coming it will help because Vega 56 is said to have a 70megahash rate, and then you could compare this results with Vega. MIning is very important for AMD , that leverage their sales and there was a shortage of supplies, now you can get a rx480 cheaper than a Rx470 because it has the same hash rate and the rx480 is more power hungry. In the upcoming days of Vega releases if it has the hash rate they say there will be a shortage of supplies. IMHO. And most miners are running linux it has a performance advantage over windows. Again IMHO the mining community is huge, linux friendly and eager to buy new hardware.

calculation on vega hash rate:

Applying this to Vega 56, it converts to 409.6GB/s divided by 7.8GB giving a hash rate of 52.5 MH/s. For the RX Vega 64, it is 483.8GB/s divided by 7.8GB which results in approximately 63.4 MH/s.

so for Vega 56 hash rate is double of the most used ethereum card (rx 470) and for Vega 64 is 2.5 times.

Most miners are using Pentium dual Core or just Celerons on old motherboards. Rocm puts a lots of thing into the table SenseMI and other technologies only found in i7 and most miners use pci express 2 and rocm is pci express 3, in the long run RoCM should outperform normal amdgpu pro performance so for miners, is one thing to keep an eye even if the increment of performance is minimal, it does take to account because miners run 24/7 365 days so in the end of the year/week or whatever that minimal increment makes a huge difference.

[Kayote]

Sorry I read your reply very quickly I thought you meant other mining applications. I'm only into ethereum but I will investigate.

[Kayote]

Maybe you should compare a Pentium Dual Core with a Pci Express 2.0 vs a Ryzen or a i7 pci express 3.0 to see if it's worthless for miners to upgrade their cpu and motherboards, and to see if rocm takes advantage of the advertised features (leverage of pci express 3.0, SenseMI, heterogenous memory, etc). It's an uneven comparison but most miners don't care much about the cpu because it makes no difference.
