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.

The software emulation of the PS2 already exists for the PS3 (in accounting terms it's a sunk cost). The only cost for Sony would be the extra 16MB of storage space (or however large the software is).

My personal opinion is that it would be in Sony's best interest to release backwards compatibility for the $399 unit as an online purchase. I think this would make very good business sense by allowing people to invest in the PS3 now, and 'upgrade' their system at a later date for a small cost.

I agree that backwards compatibility is more of a value-added feature rather than a core feature, but I think that it is a very strong value-added feature.

Like-wise I hope that Nintendo releases some sort of $20 DVD option to the Wii so that I can watch movies on it. It is obviously capable of watching movies it just needs to be enabled via software.

On the other hand if Nintendo releases a new Wii that plays movies and doesn't give me the option to upgrade my existing Wii, I'd be pissed! (but probably not too pissed since it wouldn't change my current setup, and also I'll probably be upgrading to HD-DVD which wouldn't be an option on my existing Wii anyways. But I'd still feel a little cheated.)

This is not very easily doable.

Sure, some things were software emulated, but not everything. The 40GB PS3 is now missing the graphics synthesizer and some specialized memory that was required for PS2 emulation.

Theoretically, Sony could probably even emulate these via the CPU + GPU, but it certainly isn't a "sunk cost" as Sony would have to devote considerable resources to make this happen.
