512Gflops. But probably it isn't supposed to lead(which requires 14nm), but to use manufacturing fabs fully controlled by china.

The 512Gflops is only an uncorroborated blurb posted in a press release. Thus, its highly doubtful that the chip's real world performance comes anywhere near that value.

It would be very interesting to see real-world benchmarks compiled independently.

I have grown suspicious of powers of 2. 512 anything sounds like a theoretical limit based on the number of cores.
