My stock answer on anything prior to launch is that it probably isn't true.

However to respond to "how can it beat a 5690", let's look at a couple of things:

1. This says "cryptography benchmark"
2. That work is done in 128-bit FP for the most part
3. The 5690 has 6 128-bit FP engines
4. A Bulldozer 12-core would have 12 128-bit FP engines

Generally speaking, would you rather have 6 @ 4.2 or 12 @ the 2.4 that the result shows? For highly parallel tasks like that I would much rather have more engines at a lower speed. Especially when you consider the power draw with getting a 5690 up to 4.21GHz.

I am not confirming anything here, I have no way to know if this is real or not, just saying that for those types of tasks it would be completely believable that bulldozer would do quite well.
