...which contains 10,250 slices where one slice contains four 6-in-2-out lookup tables and 8 flipflops:

On page 19: The four boxes on the left are the lookup tables implementing combinatorical logic (A/W/O5/O6/...), the eight squares on the middle/right (D/CE/CK/SR/...) are flipflops (store one bit of data each). There's a bunch of random multiplexers (the trapezoid ones, they choose one output of X inputs) scattered around. This "schematic" is of course simplified ;-).
So, 10250*6/308=199.7 fits the 8088 "IP" 200 times. Of course this is a very naive calculation ignoring any routing between cores or any peripherals to make them do anything useful, and one would use one of such a 8-bit CPU for easy housekeeping tasks, and not 200 of them. But it shows nicely how incredibly dense current FPGAs are.
Of course, just one bare chip will set you back around $120. https://octopart.com/search?q=XC7K70T (<-- part search)
