It seems everything else has come true up until now. According to the leaked roadmap from AGES back there were several key steps in the Xbox 360 revision roadmap codenamed Xenon, Zephyr, Falcon, Jasper and finally Valhalla.

From the roadmap that was leaked we expected to see near yearly or yearly revisions to the Xbox 360 hardware and just like clockwork every year since Nov 2005 has had a new revision of Xbox 360s. Valhalla was meant to be a combined Xenon/Xenos on the single die on the 65nm process. Since total Xbox 360 Jasper power consumption doesn't go much above 100W and such CPUs in the PC realm have been pushing 100W + for the CPU alone its not outside the realm of possibility.

The original die sizes for the Xbox 360 @ 90nm were:

• Xenon: 176mm²
• Xenos: 182mm²
• ED-Ram: 80mm²

The current die sizes for the Xbox 360 @ 65nm are:

• Xenon: 135mm²
• Xenos: 156mm²
• ED-Ram (80nm): 64mm²

So a Valhalla Xbox 360 CPU/GPU @ 65nm is likely to be between 220-270mm².

The reason why I pegged the design at between 220 and 270mm² is because they would likely shed aprox 20mm² if they combined the chips as they would no longer need interface buses on either end and thats a conservative number to account for them. I didn't feel like pulling up die shots or anything of the sort. They would also gain further reductions because combining the chips at that process node would require a more extensive reworking of the chips internals, its more than just a cheap shrink by any means.

So, the year is 2009, the place is Vgchartz.com/forum and the question is will Valhalla release this year? We've had squat in terms of rumours about the Xbox 360 aside from these two snippits. 1. Xbox 360 Premium/Elite consoles being slashed in price soon. 2. Xbox 360 Premium/Elite units are produced on the CSON production lines whilst the Arcades are produced on FDOU's.

So what do you think?

Valhalla would definitely be the key.

With it they could:
Lower production cost considerably
Lower power consumption
Lower heat output
Finally enable a slim redesign because both the motherboard and heatsinks could be shrunk

I would like to see a 360 using 45nm chipsets but I guess Valhalla is the final 360 revision and as good as it gets.

They have cool code names, thats for damn sure.

I thought it was a game at first lol.

Its the last of the leaked revision roadmap, there was another rumoured leak with 3 extra names and IIRC two of them were called Lean and Pure respectively. There will be a 45nm and a 32nm Xbox 360 revision.

I made a thread about this before....But only about the Xenon revision...This will be good and should be ready by March 2010 if everything is a go....I think we will only see Jaspers this year

Squilliam. Do you have a link to the leaked road-map by any chance? Thanks.

Sorry RAZ I don't really have a link to the original, but heres a link as close as possible to source because IIRC the site im linking to leaks a lot of Xbox 360 related stuff.

It will be interesting to see what happens. The only thing is how exactly is the 360 going to become slim? 1)Unless they mount the Hard Drive on the top of it, which will be stupid looking. Or 2) Finally have internal hard drives that you can change in and out.

They can reduce the dimensions so its more square, they can make it shorter and they can reduce its depth, its the width they can't do much about. An Xbox 360 slim could very well be a slightly shorter and slightly less deep console which is about as wide as it is now.
