The amount of speculation and (?) in the Specification table is funny... 😀
If Arc's top GPU is gonna be 3070 Ti level (best case scenario) and it will cost $600 like the 3070 Ti, it's gonna be a big, BIG fail.
I don't care their name is intel, they need to prove themselves in GPUs and to do that they either need to 1) beat the best GPUs of today 3090/6900XT (which they won't) or to 2) have better, a much better price/perf ratio compared to nvidia and AMD, and also great software.
So option 2 is all that they have. 3070 TI perf level should not be more than $450, better yet $400. And anything lower in performance should also be lower in price, accordingly.
Let's also not forget Ampere and RDNA2 refresh suposedly coming almost at the same time with intel ARC, Q1 2022 (or sooner, even Q4 2021, maybe). Yikes for intel.
