I'm pretty sure both brands of DX4s have 16KB write-back caches now.
However, the more "traditional" 486s (SX, DX, DX2) all had 8KB
write-through cache.

I'm not positive, but the Intel DX4 might have come at the start with
a 16KB cache.  If it did, it was write-through originally, and only
became write-back on the newer "write-back enhanced" 486DX4s.
