192 giga bits per second is a correct value, it's 64bits at 3GHz.
192Gb/s is 24GB/s as I stated.
You can't get to 192GBps total system RAM bandwidth using a single non-custom CPU. All max-out at 96GBps.
I don't understand what you're talking about.
PS4 SoC memory bandwidth is 176GB/s
Where did you get this absurd "96GBps" value? Intel Xeon Phi has 352 GB/s bandwidth (with 16 memory channels @ 5.5GT/s)
edit: Oh I see, you mean top DDR3 bandwidth @ quad channel.

So you need a least 176/24*64b = 448bit memory interface with 7 DDR3 modules working in parallel to be on par with PS4. But I'm not sure it will be as effective as GDDR5. Also DDR3 is not a power efficient solution.
