XFX Radeon RX 480 4GB
it is best
I first said that but the sapphire has 8gb
Thanks, and is it worth it buying a 8gb instead of 4gb as here the price difference is big?
With all of these cards, the 4GB is running at 1750 mem clocks. The 8GB is running at 2000 mem clocks.
For some altcoins, Ethereum for example, that results in a 10-15% increase in performance and greater power efficiency. Since the price difference is small, the Sapphire RX 480 8GB looks like a good buy. Also Sapphire is the best when it comes to RMA warranty claims.
I personally only buy the cheapest RX 470 4GB cards as I find them to be the best value for money. If you can get them for under $230, then those would be the best option.
