AMD 2010 Processor Series in Tests
 

Today we shall try to answer the following question. What's better: a triple-core CPU with 512KB L2 per core or a dual-core CPU with 1024KB L2 per core? On the one hand, the former has an additional core. On the other hand, each core of the latter has twice as much cache available. This isn't as obvious as it may seem.
