We saw some documents that shows that AMD's Phenom X4 is wining over the K8 X2 dual core marchitecture in games, next generation games, video encoding and decoding and finally rendering.

The most interesting part was that in all of these applications AMD claims a slight advantage over Intel's Core 2 Quad, but only at the same clock. This claim should be true if you compare the Core 2 Quad at 3GHz versus a 3GHz Phenom X4.

The big question is how K10 compares to Penryn, as we've heard that some Chinese colleagues that tested one got a huge performance increase from the new 45 nanometre core.
