After much back and forth bickering within the tech community, Kazuo Hirai (president of SCEI) has finally confirmed what many had long suspected... that the new 40 GB PS3 model uses a new Cell processor built on a 65nm process. While this doesn't make the new PS3 model any faster than previous models, it does allow it to consume approximately 100 Watts less of electricity when running at full load, and operate 6 dB quieter than the earlier PS3 models.
Even the earliest PS3 models ran considerably quieter than the most of the competing XBox 360 systems did, but given the PS3's use as a Blu-ray movie player, many home theatre fans found the device too loud for their liking for media playback. This new revision should bring the sound levels much more in line with other high-end home theatre products. It will hopefully be viewed favorably by environmentalists as well, as it uses considerably less power than the earlier PS3 system's did.
Hirai also stated that the new processor revision will start being used in the higher end 80 GB model in the future. As of now, the Nividia RSX GPU in the new PS3's is still being built using a 90nm process.
