AMD FX-8350 Review: Does Piledriver Fix Bulldozer's Flaws?
An anonymous reader writes "AMD just officially took the wraps off Vishera, its next generation of FX processors. Vishera is Piledriver-based like the recently-released Trinity APUs, and the successor to last year's Bulldozer CPU architecture. The octo-core flagship FX-8350 runs at 4.0 GHz and is listed for just $195. The 8350 is followed by the 3.5 GHz FX-8320 at $169. Hexa-core and quad-core parts are also launching, at $132 and $122, respectively. So how does Vishera stack up to Intel's lineup? The answer to that isn't so simple. The FX-8350 can't even beat Intel's previous-generation Core i5-2550K in single-threaded applications, yet it comes very close to matching the much more expensive ($330), current-gen Core i7-3770K in multi-threaded workloads. Vishera's weak point, however, is in power efficiency. On average, the FX-8350 uses about 50 W more than the i7-3770K. Intel aside, the Piledriver-based FX-8350 is a whole lot better than last year's Bulldozer-based FX-8150 which debuted at $235. While some of this has to do with performance improvements, that fact that AMD is asking $40 less this time around certainly doesn't hurt either. At under $200, AMD finally gives the enthusiast builder something to think about, albeit on the low-end."

I agree about multithreaded performance being important thing moving forward.
Regarding power consumption, anandtech review puts total system power consumption for Vishera tested at 12-13W more than Ivy Bridge. Scroll to bottom of page for chart. Bar and line graphs at top of page are misleading-- they put x axis at 50W, not 0W.
If you are concerned about power consumption, find 100W lightbulb in your house. Replace with CFL. You will have greater energy saving.
Here are a set of benchmarks that are more centered on the Linux world from phoronix and are thus a little less prone to intel compiler discrimination. The results seem more realistic: better and worse and similar to an i7 at different work, still hard on power usage, low purchase price.

Light bulbs are easily removable, and there can't be that many of them in a rented apartment - or even in a rented home. Take them with you, since you will need them at the new place anyway, and leave the old ones (that you saved) in their place.
