AMD this week added a 3000+ rated processor to its 32-bit Sempron desktop chip line-up. The $123 part was added to the company"s price list without fanfare. Unlike previously announced Semprons the new part contains 512KB of L2 cache - the others have 256KB. Indeed, the older Sempron 2800+ is, like the new model, clocked at 2GHz, with the bigger cache accounting for the higher performance rating. The 256KB L2 Sempron 3100+ achieves its higher-still rating despite a 1.8GHz clock frequency thanks to it being a Socket 754 Athlon 64 chip in disguise.
