Sapphire has created a new 16GB variant of the AMD Radeon RX570 video card that is specifically designed for GPU Mining. Sapphire Technology Vice President of Global Marketing, Adrian Thompson has written a blog post that details how new cryptocurrency like GRIN will require GPUs with 16GB frame buffers for maximum efficiency. Since affordable 16GB GPUs are hard to find on the market, Sapphire designed one! Sapphire has taken the initiative to obtain a port of the CUDA miner that GRIN uses. Sapphire suggests that miners should move fast to jump into GRIN as the company predicts a return of profitability for miners. Hopefully miners will stick to this cheap Radeon RX570 variant and leave the upcoming 16GB Radeon VII alone. Pricing and availability has not been announced yet. While most mid/high-end GPUs have at least 8GB of memory, very few have more than 12GB, and 16GB will be required to mine using the 2020 variant of Grin Mean AF Cuckatoo algorithm. A GPU with a 16GB frame buffer could conceivably mine both the GPU friendly and ASIC friendly algorithms for more than 2 years whereas others are limited to just the GPU friendly Cockaroo after the first year.
