John,

What is L1 cache in MediaGXm?

I haven't seen any references to MediaGXm specifics. MediaGX had 16K only I believe.

John,

MediaGXm has mere 16K unified L1 cache. The beauty of MediaGX is that this processor was designed to bypass the needs of L2 cache since the beginning with superior architecture designs. Cyrix has made an experiment to add L2 cache onto MediaGX motherboard and could not get noticeable performance improvement from the additional L2 cache.

As we discussed before, Pentium family has very s-l-o-w memroy speeds across its L1, L2 and RAM speed, comparing to either Cyrix processors or K6. Thus, the abence of L2 will put Pentiums (P54C, P55C or PII) on the knee to run today's fat application. Without L2 cache, Pentium is crippled.

Petz,

The GXm doesn't need L2 cache and has only 16K of L1 (to my knowledge).. The GX (GXi, Gxm) get their performance for a propietary architecture which is designed to maximize memory bandwidth (upto 2GB/s) without the use of L2 cache.

CYRIX/NSM Rule!
