Lower Hashrate Rx580 4GB compared to GTX 1050 Ti 4GB
Hello, 

I have found that hashrate of GTX 1500 TI (4gb) stay good (12.5 MH) in mining ethereum with nanominer (even it memory has just 4048 and the Dag size is 4143), but when I try the same with Amd RX 580 with (4080 memory) the hashrate fall down to 250 Kilohash,

I don't know why hashrate stay good in GTX 1050 Ti 4GB even it doesnt have enough memory for DAG size, but in AMD RX580 4GB Hashrate fall down even it has the same amount of memory as GTX 1050 Ti.

this is some details about my system:

Os: Debian 10, Kernel 4.19
Driver amdgpu-pro: 20.40
Driver Nvidia: 440.33.01
Cuda: 10.2
