A QX9650 & QX9770's FSB's are actually faster than the original Phenom's.
??? The original Phenom doesn't use a FSB. I was trying to say that because memory requests go through the FSB, you get much better memory bandwidth with the IMC. This means you can get away with less cache on the chip. Meaning its ok for an AMD chip to have 2MBs of L2 cache, but not so much for an Intel chip. They use the FSB to get their memory, so they need more L2 cache to store it.
