There has been the Achronix Speedster 22i HP(high performance), which was said to reach 1Ghz, produced by Intel at 22nm. That is now out of production, it seems.
I am angry for not having bought at least the 22i HD(high density) development kit, when it was available for 999USD for a time. But the software license was only valid for a year, so no-go.
They now offer embeddable FPGA IP cores targetting 750Mhz on TSMCs 7,12&16nm process.
And 'normal' FPGAs, the Speedster 7t, manufactured by TSMC at 7nm, also 750Mhz fmax.
All rather expensive and out of reach for the hobbyist :-(
