just thought I would show the insides of "Chinese market only" Pentium Wink

Left >> Gold heat-spreader marked BP80503233 SL28J
Middle >> TCP package soldered with markings face down
Right >> for reference a SL28P TT80503200

The die of the "SL28J" you may notice is larger than the SL28P (0.25 um process)

Therefore the "SL28J" was made using the 0.35 um process & the fastest made in that process as far as I know was a 166MHz

On a side note I have a Pentium board that is jumperless & auto setup up the chip as a mobile 166MHz Pentium MMX

but they way some people lately have been bidding on them, I wonder if they really understand that.

Prices of them have been the same as the more common gold-top 100s Confused
