I'm quoting directly from the article:

    Comparing theoretical peaks for 64-bit floating point
    arithmetic, the current generation of Xilinx’s Virtex-7
    FPGAs is about 4.2 times faster than a 16-core microprocessor. 

And with regards your question about titles "lately", I'd be interested to see what other submissions I've made that you think are "link-baity".

Thanks.

I think it was in reference to other titles submitted lately in general, not necessarily by you.

Sorry, I didn't mean that you have submitted link-baity titles lately. I don't think I've read any of your submissions and if I did I wouldn't know it :)

The thing is, you left out some information that transforms the way the title reads to people who haven't read the article. People will think, as I did, "Wow, they've made improvements to FPGAs and got them way faster than CPUs", click through and find out that the performance gains are currently only theoretical, not empirical and also that the 4.2x number is only for a very specific type of problem.

Whether intentional or not, the title implies something greater than the article reports. That's annoying, I like article titles to be informative not inflationary.

I think that title is a fair summary. Any title has to be taken with a grain of salt until one reads the article, anyway.
