Ryan Leung 梁興盛, CFA(@RYANHINGSHING):@lithos_graphein @ShanghaoJin @orstep3oxj @xueyuanjoey Yes, that’s what I calculated in the past. I think he wanted to calculate the cost of a larger chip like the Ascend 910B this time. So, I think the cost of a wafer is ~1.4x–1.5x, and SMIC’s yield could be 1/2 to 1/3 of TSMC’s. In this case, it could be 3x
