This Japanese blogger purports to have an image of the PS3 development kit. He says that the Cell chip in the dev kit runs at 2.4GHz, and the GPU is a “chip that is ‘yet-to-be-released’; probably a pre-release G70 since RSX for PS3 has yet to tape out. Not only that but he indicates that the GPU is currently working through a 4x PCI-Express slot, offering just a fraction of the bandwidth the RSX will enjoy through the FlexIO bus in the upcoming Playstation.”

These kits were supposedly used at E3 to show off the realtime demos. This means that the final production PS3s will be much more powerful than those used for the demos at E3.
