R9 270 has 20 CUs at 925 MHz. PS4 has 18 CUs at 800 MHz. Both have same amount of ROPS. R9 270 doesn't share its memory bandwidth with a CPU, the PS4 does.
Let's wait and see how low level can you go on this STEAM OS. If something like Mantle can be used to code for games in Valve's new box, then I expect the hardware to be just as efficient as it is in consoles. In that scenario even the vanilla R9 270 will outpace the PS4.
