Today we'll take a closer look at AMD FX-8350, the top processor of the Vishera series, based on the Piledriver microarchitecture.

Firstly, we'll compare the newer top AMD FX-8350 with the older top AMD FX-8150. As you see, they have similar specifications: four 32-nm modules with a large L3 cache, the same TDP and Turbo mode core/cache frequencies. However, the novelty's base clock has increased by more than 10 percent, so we expect it to have a significant advantage in multi-threading tasks (as opposed to single-threading tasks, where only architecture improvements can help).
We have also thrown in an AMD A10-5800K. Though it belongs to a different class of processors, it has the same architecture and similar frequencies, so it'll be interesting to compare the CPUs in few-threading tests. Moreover, if you're satisfied with the overall price/performance ratio of the cheaper A10-5800K, you won't have to look for a more expensive processor.
The fourth CPU, Phenom II X6 1100T, has outperformed the FX-8150 in some tests. Therefore, such a comparison with the today's CPU looks interesting as well.

We compared AMD FX-8150 with Intel Core i5-2500 and Core i7-2600, because it had fit just between them in terms of price but then became as cheap as low-range Core i5 models, yielding its original position to AMD FX-8350 and FX-8320. Judging by the price, the latter pair should be compared with upper-range Core i5 CPUs, but we'll take Intel Core i5-3570K as well as Core i7-3770K to provide a more comprehensive overview.
