AMD Reportedly Working for Navi 10/12 Based Mining Cards: Up to 55 MH/s Hash Rate

According to a few recent patches to the AMD Linux driver, Team Red might be working on a couple of miner-centric graphics cards based on the older RDNA 1 architecture. The details indicate that there will be two models, one based on the Navi 10 die and the other on Navi 12. While the former would make for a capable Ether mining GPU with a hash rate between 54-56 MH/s, roughly the same as the RTX 3070 and the RX 6800 XT, the Navi 12 die is limited to a 128-bit bus and a bandwidth of just 224GB/s.

Furthermore, the 4GB variant will not worth be able to miner Ether in most cases due to the algorithm DAG size being 4.117GB. Even if it does with a multi-algorithm protocol, the returns will be pretty low. Other currencies like KAWPAW should be compatible but that will net you just a dollar worth of profit for an entire day of mining.

The Navi 10 is another story altogether. With a bandwidth same as that of the RTX 3070 and the RX 6800 XT, it can manage a respectable 54-55 MH/s which can amount to profits of nearly $5/day per GPU. With a memory overclock, you can extract up to $6-6.5 from the card with little to no increase in power.

NVIDIA’s CMP 50X miner has an Ether hash rate of 45 MH/s, around 15-20% lower than the RX 5700 XT (full-fledged Navi 10). Only the 90X which is based on the newer GA102 (Ampere) die offers a higher hash rate of 86 MH/s.

Considering that AMD can barely supply a dozen graphics cards a month to a large state like the US, it’ll be interesting to see their reasoning on starting a line of miner-center graphics cards based on the same process node.
