Hello,
I have a little rig with 6 RX 4xx/5xx GPU.
I would like to change one or more GPU with a 6600/6700/6800 XT. After a good tuning (overclok/undervolt), which is the max hashrate and the power consumption of each of this card?
Thanks
If you looking to add some GPUs to your rig, this link is a good point to start:
https://www.kryptex.org/en/best-gpus-for-miningHashrates are about accurate (+-) 2-3 Mh/s depending on your OS, OC tuning, and silicon lottery. Prices will depend on your country, but most of the GPUs could be found at better prices in the USA.
If you looking for replacing 8G Polaris cards with new models, I would not recommend it, for me does not make sense. They still work pretty well and are efficient. Except if you bought them recently second-hand, they should be paid off and just will make a profit for you. Buying new ones will just eat your profit.
