Frankly speaking, the results of SYSmark 2007 benchmark that estimate the average performance in general-purpose applications do not look too optimistic. On average, the new triple-core Athlon II X3 435 processor falls a little behind dual-core Intel Pentium E6500. It obviously happens because of relatively small cache memory of the newcomer: we clearly see that from the lag behind the Phenom II X3 720 working at a lower clock speed.
However, we shouldn’t regard the picture as too dramatic. Compared with other Athlon II processors, the new Athlon II X3 435 looks very good, running neck and neck even with the quad-core Athlon II X4 620. In other words, three cores are quite enough for most contemporary tasks. Especially in Windows 7 operating system, where the new task manager is way better optimized for multi-core architectures than in Windows Vista.
