We had a chance to see the first Barcelona based Quad core CPU from AMD. This is the desktop part codenamed Agena FX and it is live and running at Cebit 2007.
We were asked not to take the photos but we actually had one in our hands. The new Quad core will run at socket AM2+ and 1207+ and probably at the older ones as well.
The system is running, sampling and it needs a new chipset to work something better than 690 that was just released. Lets call it 790 till we get more details.
The chip itself looks like any Athlon FX CPU has a big heath spreader and a loads on pins below.
