Does Dolphin benefit from bigger L2 or L3 cache size

large L2 or L3 cache size will speep up dolphin?

thanks

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 !!

Yes but not a lot.

I don wanna highjack your thread, but... What are these L2 and L3 caches btw?

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.
