While he is quite ignorant about GPU:s. The Book definition of Many-core is several tens to hundreds of cores. And xeon-phi fits the description of several tens of cores. The core doesn't really need to be designed specifically for many-core to fit definition of many-core.

While people often seem to think many-core and OoO are mutually exclusive, I consider that less aggressive OoO with reasonable ISA maybe optimal for many-core. Each core needs reasonable amount of cache to not overload the communication network for data traffic.
We both know if some-one would make a 100 core processor today for server you can fit OoO logic to power budget, as long as it isn't too aggressive.
