Where does the fx 6xxx and fx 8xxx crush the i3 and i5? Considering the TH cpu comparison chart, the 4th gen i3 and fx 6xxx are about tied with a slight edge to the fx in 3ds max. The 4th gen i5 beats the 8350. In blender, the i3 4th gen is tied with the fx 8320 and the i5 4430 beats the fx 8350. In handbrake video encoding, the 4th gen i3 beats the fx 6100 and fx 8350 is tied with the i5 4690. In totalcode video encoding the i3 and fx 6xxx are nearly tied, slight edge to the fx 6xxx and the i5 (3rd gen mind you) beats the fx 8350. The i3 and i5 eat the fx chips lunch in .wav to .acc audio encoding. Adobe after effect the i3 is slightly faster than the fx 6100 and the i5 (3rd gen again) stomps all over the 8350. In adobe premier pro the fx 6xxx slightly bested the i3 and the i5 4690 outperformed the fx 8350.
About the only real world benchmark I can find where the fx has any real performance gain is in 7zip. I'm hard pressed to find any other non gaming real world scenarios where the fx trounces all over anything but it's own feet. It's being matched or bested at a rate of 2 cores vs 6 or 4 cores vs 8 in audio encoding, video encoding, 3d rendering, photo design software. So basically if you spend a good portion of your time unzipping files, get the fx. For everything else, go with intel.

This wasn't cherry picking, it was simply going through the list of various uses people are likely to use their pc for. Everything from audio to video to image processing, multiple video editors since that's where amd's 'moar cores' are supposed to shine. The bottom line is amd isn't bang for the buck, it's less bang for less bucks. Products that compare in price often compare in performance which coincidentally is why they're priced that way.
Some people have a real love for amd and so will continue to promote them in spite of real world results feeling some sort of personal hurt over business deals that occurred 7yrs ago. That's the definition of fanboy-ism. I personally don't care who has the better hardware, if it were amd then I'd buy amd. It happens to be intel so I run intel. Amd's isn't going to send me a fruitcake at the holidays with a warm cup of cocoa and invite me over for the holidays. They're going to snatch my money same as every other corporation.
I didn't mention power consumption since I happen to live in the u.s. with relatively cheap power costs. It won't make much of a difference to my monthly power bill. Though I might feel differently if I lived in a country where the power costs easily 4x what we pay in the u.s. Intel does use far less power under load. It would be "anti amd" if this were all just opinion and not backed by benchmarks but it's not. It's as easy and looking at the comparisons and seeing a clear difference.
I have to wonder if people always scrutinize the manufacturer of every product they use on a daily basis to verify whether they adhere to a high moral business practice or only when it comes to processors. It would be kind of odd for people to shake their finger at intel, shaming them based on morals while wearing clothing made in sweatshops or using various other goods where the laborers are treated unfairly or the company has ever made an 'unfair' business practice - perhaps ate food produced by a large corporation that did shady land trade deals to push out small independent farmers just so they could save $.10 on their potatoes or peaches. lol.
