Details of the Cell's 45nm shrink have now appeared. The new version of the chip has dropped in power consumption by 40%.
This will cut costs as it uses less silicon then the 65nm version and the lower power consumption means a simpler, lower cost cooling system.
Production is due to start in the summer so expect them on the shelves in time for Christmas. I also expect they cut the price again just before Christmas.
Details and pictures of the 45nm shrink are here: (translated) (original version).
Chip geeks can get the full shimmy at RealWorldTech.

On another note details of "Cell 3" have emerged.
"Cell 3" has been seen on IBM slides before as a Cell with 2 PPEs and 32 SPEs but nothing more has been said about it.
According to a presentation the SPEs will be getting some redesign to reduce latency and improve bandwidth. The PPEs on the other look like they light be based on POWER7 technology.
Sounds like it could be a pretty serious piece of kit. It's not known if this particular version will go into a future PS4 or if it'll get it's own "game" version.
If you're wondering what happened to Cell 2, this is the soon to appear HPC version, now named the "PowerXCell 8i".
Details of the PowerXCell 8i and the roadrunner Supercomputer it'll be sitting in are in this presentation [PDF], Cell 3 stuff is on the last slide. |

Games house Insomniac have set up a new website to share their knowledge on PS3 development around the development community.
The idea is really to open source knowledge so developers can share how they do their work hopefully raising the quality for everyone while lowering game development costs.
What may sound like an unusual move for a company is actually what the scientific community have been doing for centuries, and it's certainly worked for them.
There's a press release, a website and on the same note they have some slides on SPU programming. Plenty to read if you're not feeling very tired... |

Unless you've been hiding under a rock for the last few weeks you will have head HD-DVD lost and Blu-ray won.
You would think Toshiba would would now be singing the Blus but probably not actually.
The PS3 is not just a Sony product, like the PS2 before it, the PS3 is produced by both Sony and Toshiba, with Sony selling it. Cell is a product of 3 companies, Sony, Toshiba and IBM and just after the defeat of HD-DVD Sony sold their chip plants to Toshiba.
Toshiba had in effect, rather smartly backed both horses.

Not many appear to have noticed it but the HD-DVD is actually a rather rare event - a major defeat for Microsoft (they provided the HD-DVD software). |
