[olug] AMD or Intel for multi-core apps?

[Sheldon, Roger W]

Intel fairs better even with 4 core's. They have better rendering video from what I read on web. Intel Corei7 2600K (4core) performs just as good as the AMD FX8150 eight core. They AMD Bulldoze was coined faildozer because it failed to live up to expectation. Either CPU's are good and work good for multi-threaded apps. The FX8150 doesn't do so well in single threaded apps, even the AMD Phenom 1100T beats it or comes very close. The diff comes down to how long do you want to wait really. If you are rendering huge video/images then the biggest Corei7  with Quick Sync is the way to go. AMD will do the same thing just takes a bit longer. I've used AMD's a lot and they are good workhorses, reliable and is the cheaper option. My next rig is going to be a monster though and I will be going w/Intel mainly because of the Quick Sync and 65w vs AMD's 125 for fx8150. The Intel Corei5/7 beats AMD in a lot of benchmarks and they are the top performers. If you want the best performance right now it has to be Intel Corei7.

I may be in the market for a new desktop CPU/mobo for the first time in
4.5 years.  I haven't kept up on CPU technology, so I need some advice.
TomsHardware.com used to compare CPU's, but no longer, it appears.

Most (but not all) of the CPU-intensive tasks that I perform (photography
related) are pretty well multi-threaded and operate on large datasets, and should make good use of multiple cores.  Of course, there are still some single-threaded operations that I'd like to speed up, too.

My current box has a 2-core AMD CPU, because the 4-core Phenom had just come out and was still buggy at the time.

Philosophical issues aside, do you have any feel for whether I'd be better off with an 4-core Intel i5/i7 or a 6-8-core AMD CPU?  Are the individual cores of the i5 or i7 significantly faster than those of the AMD?

I haven't done exhaustive research yet, but these CPU's have caught my eye:

AMD FX 3.8GHz (4.1GHz Turbo) 6-core 125W, $140

AMD FX 3.6GHz 8-core 125W, $190
http://www.newegg.com/Product/Product.aspx?Item=N82E16819103960

Intel i5 3.4GHz (3.8GHz Turbo) 4-core 77W, $215
http://www.newegg.com/Product/Product.aspx?Item=N82E16819115233

Intel i7 3.1GHz (3.9GHz Turbo) 4-core 65W, $305
http://www.newegg.com/Product/Product.aspx?Item=N82E16819116503

The only 6-core i7 is out of my price range at $570.
