90nm chips still in use by PlayStation 3

With the release of the 40GB PlayStation 3 nearing worldwide proportions, some took one look at the specifications sheet and assumed that it contained 65nm chips after noticing that the latest SKU is a good bit less power-hungry than the 60 or 80GB models. While the 40GB PS3 does indeed draw less juice, Sony says that the latest hardware still runs 90nm chips.

According to information received by German publication Heise Online, the new 40GB PlayStation 3 hardware does not yet include 65nm chips, but rather still makes use of the same 90nm technology as in all other PS3 consoles. Sony said that 65nm chips would be introduced sometime in the coming months.

So how does Sony account for the power consumption drop from 200 Watts down to a more palatable 135 Watts? Apparently it’s due to improvements and modifications on the original design.

For one thing, the 40GB PlayStation 3 no longer has to house and power any chips related to PS2 backwards-compatibility. That means that the new hardware is completely without the Emotion Engine+Graphics Synthesizer chips and memory.

The 40GB PS3 also does not include the added hardware to support a memory card reader and only has to power two USB ports rather than four, leading to a further reduction in power consumption.

To follow up on that it was previously reported the ps3 version would only run at 30fps with no AA, where as the 360 version runs at 60fps with AA. Now it is reported that this is not true, and they will both run at 60fps w/AA. I guess we will only know for sure when both game are released. I played the online demo for 360 and i was blown away, I can't wait..
