Comment by VMUNIX (andres_leitner[at]yahoo.com.ar):

I'm wondering what "fastcache" stands for ? and why is it only 2Kb instead of 8Kb

The Cyrix 486S is a i486SX compatible processor with 2kB write back cache. All the other cpus on the market at this time had no write back cache. The 486S also had a special signal (write burst), the usage of this depends on the motherboard design. These both things brought cyrix a speed up of around 6% (to a i486SX).
