We know that only GPUs with 8GB or more can mine Grin – a new and very popular privacy coin that is being developed by the community. Such a high VRAM requirement considerably limits the array of cards that are compatible with the coin. While this means that Grin is harder to mine than most other coins, the project is getting a lot of attention lately, at the point that Sapphire Technology, a leading manufacturer and global supplier of components and commercial solutions, launched today a GPU oriented specifically to mine this coin.

By “oriented” I mean that the RX 570 16GB card was designed to mine this specific coin in mind, however it can also be used to mine other cryptocurrencies too, obviously. If you have been following my blog for a while, you have probably noticed that I use a lot of Sapphire cards in my mining rigs. I’m really excited to know that Sapphire seems very interested in developing and making new products for GPU mining.

Quoting the words of Adrian Thompson, the Global VP of Marketing at SAPPHIRE Technology:

The launch of the RX 570 16GB Mining GPU presents an exciting opportunity not just for SAPPHIRE but for early Grin Coin miners and the cryptocurrency market as a whole. Future products will include new 16GB Graphics additions’ to SAPPHIRE’s line of INCA and MGI Series of dedicated blockchain systems. We’re thrilled to be bringing this and future blockchain products to market.Adrian Thompson

Some of the most interesting features are:

  • Dual ball bearings on fans (YES!) – dual ball bearings are several times more durable compared to the traditional sleeve bearings used in most modern GPUs. Mining requires a card to operate 24/7 on full load, which puts a lot of pressure on the fans. Having dual ball bearings can increase the lifespan of your GPU fans for 1-2 years or more.
  • SAPPHIRE Quick Connect Fan Technology further increases the lifespan of your GPU by allowing you to easily clean your fans and even replace them with new ones.
  • ROCM 2.0 accelerated Grin Miner for PCIE 3.0 platform
  • Can mine Cuckatoo 29+, Cuckatoo 31+ and Cuckatoo 32+, though the latter requires a driver update
