AMD seems to be working on RDNA cards for crypto-raters too


The first signs that AMD may create a specialized accelerator for mining cryptocurrency appeared back in October 2020. The Linux kernel update added a new Navi 10 based accelerator with the ID 731E. This card, as it was clearly stated in the description, will not support DCN (Display Core Next) and VCN (Video Core Next), that is, we are talking about a GPU without the ability to display an image.

This graphics card can be used either to speed up computations when working in clusters or to mine cryptocurrencies. According to a new March 3 patch, AMD has created a Navi 12 GPU that is also devoid of VCN, which is the ability to display an image. The latest GPU came just after NVIDIA made the announcement of the mining solutions expected to launch later this month.

Interestingly, Navi 12 is not available in any free market Radeon graphics card. It was designed specifically for the Apple Mac as the Radeon Pro 5600M. This is the only Navi 1X GPU with HBM2 memory. There are no mining tests available for him, so it is difficult to predict how well he will perform in the mining of cryptocurrencies.

In terms of specs, both Navi 10 and Navi 12 offer 2560 stream processors (40 compute units). Navi 10 is available with 8GB of GDDR6 memory, while Navi 12 has 2x 4GB HBM2 memory stacks. GDDR6 memory has 448 Gbps of bandwidth, while HBM2-based Navi can offer 394 Gbps.

According to the words quite a reputable informant Komachi, AMD, no later than November last year, began to prepare variants of the RX 5700 XTB, RX 5700 B and RX 5500 XTB specifically for crypto-accelerators. These may be working names for new cards, but it is unclear if AMD would want to use the Radeon brand for such accelerators.
