When the chips worked they had better perf/gate, but Intel had a lot of yield issues, making the perf/$ ratio worse.

That means that at the same power limit and the same number of active cores the Ice Lake Server clock frequency is much lower, or at the same clock frequency and same number of active cores the power consumption of Ice Lake Server is much higher. The SuperFin 10 nm process used by Tiger Lake allows much higher maximum clock frequencies, up to 5.0 GHz, than the Ice Lake Server 10 nm process, and it also has a better perf/W, but even the SuperFin 10 nm does not reach the perf/W of the 7 nm TSMC process. If the previous claims made by Intel are true, the process used for Alder Lake, now renamed "Intel 7" will be the first Intel process that is better in perf/W than the 7 nm TSMC process. Nevertheless, it will be still worse than the "5 nm" process that has been used by TSMC in high volume products (Apple) for more than a year.
