Performance during Video Encoding
Video encoding is the type of work that AMD processors are especially good at. The advantages of Phenom II X4 965 over Core 2 Quad Q9550 is about 15% on average, which is a pretty impressive result. However, even this serious advantage is no problem for the Core i7 CPU supporting Hyper-Threading technology. As a result, Phenom II X4 965 will be able to compete successfully only against those Lynnfield CPUs that will belong to the Core i5-700 series, but not against the Core i7-800 supporting this technology.
Performance in Video Editing Applications
It is quite expected that during video editing the situation is pretty much the same as during video encoding (it is especially true for the indisputable advantage demonstrated by the CPUs with Hyper-Threading support). Some consolation for the AMD fans could be the fact that Phenom II X4 processors do pretty well in Premiere Pro and even outperform the competitor from Core 2 Quad family. However, do not forget that we are comparing the new AMD processor against the previous generation Intel solution that has been in the market for almost two years.
Performance in Image Editing Applications
The new Phenom II X4 965 performance almost as fast as Core 2 Quad Q9550 in the image editing applications, but still is about 4% behind on average. As for the comparison against a more advanced Core i7 CPU, there is not a single chance: just take a look at the diagram and see for yourselves.
