Quad Core Opteron Processors
As most of us know, a processor's level 1 & 2 caches are where most of the advanced calculations are processed. Well, the highest concentration of level 2 cache AMD ever implemented into it's processors was 2 Megabytes. Given, 2 MB of L2 cache is a lot compared to the previous Skt A 256 and 512 KB caches; but now AMD pushes the envelope and develops a quad core processor with each core containing (in respective models) 1 MB to 2 MB of L2 cache. Now more calculations can be processed at higher clocks. (For those it may concern: That means 4 MB & 8 MB models :)
Will this level 2 cache expanding trend continue on to the level 1 cache?

I don't know much abot the caches but it seems to make sence if L2 gets bigger so should the L1. so yes they will folllow teh trend
With 4 cores you'd prolly expect the L1 cache to rise. However that's not the case; the processor will remain having 2 layers of 128KB of L1 cache. Meaning 256KB cumulative. However that was the rule for DUAL core; not QUAD core; they may very well institute 4 layers of 128KB.
well, if my knowledge of L1 & L2 is right, as the L2 gets bigger, the L1 can stay the same size, BUT if the L1 gets bigger, the L2 MUST get bigger.
Well actually you could have no L1 if you wanted to; the size matters yes; but it's not a locked ratio.
