Looking through a few of the reviews for AMD’s new Bulldozer line of cpu’s, you get a sinking feeling, realizing that AMD simply cannot compete with Intel’s Sandybridge processors. There are a dozen or more reviews online now. Here are a couple if you are interested:
I was mostly interested in Bulldozer’s ability to run X264 encoding. This has been one of the very few bright spots for AMD in recent years since it can make use of multithreading. Even here the best of the Bulldozer cpu’s falls behind in overall performance, though not by much. The FX-8150 does have the fastest second pass encoding in x264 when compared to the i7 2600K, i5 2500K and X6 Thuban processors, but the lower priced Bulldozers can’t even beat the earlier generation AMD X6 Thubans.
Video encoding was one of the only good scores in the reviews I’ve seen, so the only real reason to buy one of these cpu’s is if you are setting up a machine dedicated to working with multithreaded encoding programs. And even then, you’d need to invest in the FX-8150 to get performance beyond that of the old AMD X6 Thubans. For a general purpose machine, the Intel cpu’s are clearly superior.
