Hello I was wondering if anyone could tell me which to get AMD fx 4170 or the phenom ii 980 BE i know that the black edition costs more don't factor that in to your answers i just want to know which one is better in sheer performance.

Core for Core, the old stars cores (phenom II) outperform the new bulldozer cores by a descent margin. The FX will OC higher, and will bring the on par performance wise. The Phenom II will eat up a bit more power and run a bit hotter.

Pure performance, the phenom has a slight edge, but overall/price I would go with the FX.

The 4170 is poor, it get's out gamed by a i3 dual core. The 980 is much better than the 4170.

(note the 4100 at 4.5ghz is faster than 4170)

This kind of thing needs to be spread more often.

:??: 
but 4100 and 4170 are same chip, so 4100@4.5ghz and 4170@4.5ghz will be equal

He means faster than the 4170 stock.

According to AMD, a module does 80% of the work of a dual core cpu. http://techreport.com/articles.x/19514 <-- note this is 1 year before BD release

With that in mind, the 4XXX series is a dual module chip. Its called a quad core because its 80% compared to intel's 30% for HT.

4 cores *80% = 320% ... just over a tri-core phenom.

The other side is that when you use 2 cores in a module, you lose 20% per core performance because it is different than intel's HT. In order for the 4xxx to keep up with the phenom II, it needs 20% higher clocks. there are exceptions where the FX's new instructions help, but for the most part, the 41xx series are not and cannot be as good as the phenom II.

Yeah, but chances are the more expensive chip will be higher-binned, meaning greater likelhood of better overclocking potential.

finally a thread that speaks sense of FX chips poor performance without delusions of it being faster with windows 8 and cherry picked benchmarks. Phenom>FX any day.

Go with the 980BE on a nice AM3+ motherboard and when AMD release a worthy BD chip, upgrade.

Take the 980, it is tried and trusted architecture, which is still proficient today, what it isn't is efficient, but form over function is silly, so you want to game then the 980 is the stronger chip.
