Dolphin Uses Raw Processing Power and dont make much use of L2 or L3 cache ! performance increase may not exceed 1~2FPS upgrading from L2->L3 !!

My PC
AMD Athlon II X2 250
Kingstone 2x2GB DDR3 @1333Mhz
6850HD 1GB GDDR5

Yes but not a lot.

This is a special, very fast type of memory included in the processor. It's used as a "link" between the processor and the RAM.

cache size and latency also determine raw performance.

well , i didnt know that Smile !
- you mean that raw processing will be better if i updated from my athlon II x2 250 to a Phenom II with an L3 level of cache(with the same clock Freq.) ?? Would it increase performance to go for more L3 cache ? will it increase it even more if i go to higher L3 cache capacity ?

AMD chips are limited in instruction pipe performance for the most part

upgrading from l2 -> l3? You can have more l3, but it's slower than l2.
