Let the truth be known about the 65nm PlayStation 3

While neither Microsoft nor Sony has been upfront about the process technology used in their consoles, enthusiasts have had little trouble identifying the different hardware revisions of the Xbox 360. On the other hand, the 40GB PlayStation 3 has everyone guessing just whether or not it uses 65nm technology, with some saying “yes” and others saying “no.” As it turns out, both sides are partially correct.

According to an AV Watch interview with Kazuo Hirai, president of SCEI, the Cell Broadband Engine used in the latest PlayStation 3 production is indeed from a 65nm process. This fully explains the reduced power consumption numbers posted by the new 40GB PS3. The 40GB PS3 now consumes around 100 Watts less during maximum load when compared 90nm Cell/B.E. consoles.

While the PS3’s CPU made the jump to the 65nm process, the GPU is unchanged. Hirai said that the RSX chip is still at the 90nm process, but did not indicate if the GPU would be moved to the 65nm.

As reported by owners of the 40GB PlayStation 3, the newest hardware is the quietest yet. The new PS3 supposedly outputs a noise level of 30 dB, about 6 dB less than the previous model. This improvement is will be greatly appreciated by home theatre enthusiasts using the PlayStation 3 as a Blu-ray Disc player.

At the expense of having a more power efficient and quieter machine, the latest PS3 hardware gives up all PS2 backwards compatibility and the ability to play Super Audio CDs (SACD).

Hirai also revealed that the attributes of the 40GB SKU will soon apply to the entire line family of PlayStation 3 consoles, as the 20GB and 60GB models – the ones with full backwards compatibility –- are no longer in production for any market in the world.
