We have shown you a couple of CPUz validation shots of AMD's upcoming Magny Cours CPU recently.

This little darling from AMD is supposed to be a full 12 cores worth of CPU power. For many the thought is that this will be 2 Istanbul 6-core CPU bolted together in much the same way that the original Intel Quads were.

However, not everyone thinks this is the case. Istanbul (was Constantinople, now its Istanbul…) has a pretty high TDP so putting two of these together would be a little bit of an issue. You would need some serious cooling and power to run something like that.

The solution could be to using something like Lisbon instead. This is slated to be a low power 6-core Opteron that will launch in 2010. Now, this is a great solution and one that may just be the case but, if it is then why do we hear rumblings of heat issues when running the current Magny Cours Early Engineering samples.

This certainly bears more investigation; we will be back with anything we find out.
