i dont understand 1 thing. mining is all about compute power right? 6900 has twice more compute power than 5700 then.it suppose to be at least 100mhs. i dont understand it.

Minins ETH is very dependant to memory bandwith and memory latency...

The 6800/6900 have a bandwith just around 10% more than 5700. The remaining question if the impact of the infinity cache: due to its small size relatively to the DAG size of ETH, it should have a minimal impact on ETH mining.

ok then why radeon 7 has : 1,024 GB/s bandwith performing worse than 3080 which has less memory bandwith: 760.3 GB/s .

Both bandwith and core are used for ETH: for radeon VII, it is probably limited by core computation, for RX 6900 xt, it is mostly limited by bandwith.

For RTX 3080: you should downclock the core at around 1200-1300 mhz (to decrease power consumption almost without losing hashrate) and overclock memory at +1000mhz (around equivalent 10000mhz or more) to have the highest hashrate. Therefore you can conclude that this card is more bandwith limited for ETH mining than compute limited.

RX 5700 is well balanced for ETH mining between compute power and memory bandwith.

hehe could very nice card if there was 3080 chip with radeon 7 memory

very nice if there was 6800 chip with radeon 7 memory ))
