- Much discussion about the Zeos cache, Re: price...
-
-
- But your upgrade assumes the motherboard has a cache controller and the
- Zeos plug-in is for a cache-less board and provides a 128K 2-way associative
- cache AND controller. I'd say it's truely worth $120! The other $80 could be
- written off as single source profit.
-
- Of course ZEOS intentionally sold the cacheless board thinking that it was
- a fair cost-cutter and that the add-on was an easy sale. But in all fairness,
- the cost of a 2-way set associative controller is significant and with it, a
- 128K cache is roughly equivalent to a 256K direct mapped cache in terms of
- hit rate.
