I just saw this on wccftech, and I'm confused to be honest

I believe that AMD GPUs will be better for mining, but if we do the math, 120Mhs of 3090 RTX, are doing 3.43 USD daily, according to Nicehash Calculator
To gain 1.5 times more, the hashrate of ETH should be 180Mhs Shocked

It's insane, and if this is true, Infinity Cache is something big for miners

I don't know what to think right now, this is not good news, because nobody will have opportunity to buy cards this year Angry

If this is talking about ETH then it looks like they just applied AMD's claimed "Infinity Cache" memory bandwidth boost of around ~2x over a 384 bit bus:

384 bit bus bandwidth for GDDR6 at 16 gbps = 384 * 16 / 8 = 768 GB/s
With AMD claimed bandwidth boost of ~2x = 768 * 2 = 1536 GB/s
Which gives a theoretical zero latency ETH hashrate = 1539 / 8192 * 1000 = 187.5 MH/s
3090 gives about 120+ MH/s

So 187.5 MH/s is about 56% more than the 3090's 120 MH/s

Looks like they just applied some math to get those numbers. Guess we'll know soon enough how the infinity cache actually affects ETH mining in reality vs. theoretically.

taking into account that ETH DAG is too big for the cache, I don't believe this rumoured performance. Beside I am not sure that the whole 128 MB space will be available for caching portion of the DAG...
