Even in default frequencies the FX 8120 is faster than 2500K in multithreaded apps and it is $35 cheaper. And the 880G motherboard do have an integrated GPU.
Then when both CPUs will be overclocked the 2500 will loose, it takes a 5GHz Core i5 2500K to win in multithreaded apps aganst a 4.8GHz 8-core FX CPU.
Now, let's clear this one up once and for all, Im not an AMD, Intel or NV fanboy. Just because a person disagrees with you about a CPU or a GPU etc doesnt make him/her a fan boy.
I dont believe that FX sucks, perhaps the FX8150 is not suited for enthusiast and Overclockers but up to FX8120 they are very competitive in price per performance against Intel's offering when Overclocked. FX do give you a better multithreaded performance at the same price vs Core i CPUs and up to the $200 mark they are very compatitive in performance.
I could call you a fan boy because you dont realize that at a cheaper or lets say equal priced FX8120 can be competitive against Core i5 2500K. It looses in some and wins in others. Does that make it sucks ?? NO. Did i called you a fan boy before ?? NO.
Have i ever said that FX CPUs are Superior ?? NO
Have i ever recommended the FX8150 ??? NO.
Not everyone can or willing to spend $1K-2K for their PCs. On a tight budget $35-50 can give you something more. So yes i believe that $35 in savings here, another $35 from a different component can make a difference for a lot of people. If that wasnt the case, everyone would be buying the same CPU, AMD and Intel would only produce a single CPU for everyone
I dont know what happens in the US, but in the rest of the world the AMD Phenoms are EOL and cant be purchased anymore. Plus, FX has lower power usage(stock speeds), plus more ISA's (AVX etc).
I havent used the default FX heat-sink to find out the maximum OC of the FX8150 but from what i read from others they can reach 4-4.2GHz with 1.33-1.35V. But even if you use the Intel heat-sink and only OC 2500K to 4.2-4.4GHz, then again 2500K will loose in multithreaded apps against a 4.7-4.8GHz 8-core FX. Not to mention at the same price point.
My belief is that FX CPUs are price/performance competitive when OCed up to $200 mark. Now, i dont say they are the better choice for everyone, but they simple dont suck
Maybe so, but dont forget about power consumption and heat output. Plus, a CPU does more than run multithreaded benchmarks all day, you have to look at actual real world gaming performance too.
