    I think there is misunderstanding, I agree the video doesn't have full BOM of product but I was specifically talking about 6nm IO die cost and trying to make a point that a similarly sized 4nm N44 doesn't significantly increase the die cost, infact it is about the same as similarly spec 204mm²...

    First have a look at this Then correct me if I'm wrong. If a 122mm² 6nm io die cost just $21 to manufacture and even if 4nm wafer price is 75% more than 6nm, a ~130mm² 4nm die would only cost ~$40. That's very similar cost to a 204mm² 6nm N33. Now given that performance of N48 with 64CU is...

    RX 7700XT and RX 6750XT are up for $400 and $330 respectively on newegg, both 12GB cards. Do you really think an 8GB card worth single penny above $300 in 2024? And a GPU of N44 wouldn't be good for ray tracing either. $250 is the most optimistic price for N44. $270 seems plausible for replacing...
