GPU ASIC Quality Thread

[CoM1ner]

Hello Bitcointalk!

I wanted to start a thread to gather information about ASIC quality for GPU's. As you know, most miners run air cooled systems where ASIC quality plays a role in better overclocking, less leakage and the ability to run lower voltages.

A good way to find out your ASIC quality is to use GPU-Z. This tool can be found below:

Installer: https://www.techpowerup.com/gpuz/
Portable Version (No Install): http://portableapps.com/apps/utilities/gpu-z-portable

After downloading GPU-Z, click the menu button at the top right of the window (Three parallel horizontal bars) then click the "ASIC Quality" tab.
The ASIC quality is read as a percentage. If you could post the model of the card and ASIC quality, we can gather information about which cards tend to have higher ASIC qualities.

My results are listed below:

MSI Gaming RX 480 8GB: 64.1%
MSI Gaming RX 480 8GB: 67.0%

MSI Armor RX 470 4GB: 63.3%

ASUS RX 480 8GB (Reference): 73.1%
ASUS RX 480 8GB (Reference): 84.4%

Sapphire Nitro R9 380 4GB: 67.0%

Just to make clear

ASIC quality != OC potential

It has an impact on the required Vddc for a certain freq.
But it does not correlate much with the OC potential.

As far as you want to run your GPU underclocked & undervolted higher Asic quality is better regarding power consumption.

ASIC quality is only important for Engine core clock.

Most of us are mining ETH and we only OC the memory not the core clock.

And there is no such thing as Memory Asic quality.

I am actually switching around to different algos depending on profitability and testing purposes. My friends also mine multiple other algos, mostly Monero. I understand that you may mine Ethereum specifically, but there are others who mine different algos. This was more of an attempt to gather information for future use. Ethereum is supposed to go Proof-Of-Stake in the future, resulting in many miners looking to mine other coins from Ethereum.
