Microsoft Moving Into Chip Design With Xbox Next

adamsmith_uk writes "According to ZDNet, Microsoft will more actively participate in chip design for the next version of its Xbox gaming console, tentatively called Xbox Next. By switching from using relatively standard parts to more customized silicon, the company can better optimize its game console, due in 2005. At the same time, the move potentially gives the company a toehold in a completely new market."

Re:How much...

do they want to lose per console this time? If they use re-engineered pc parts, they stand to lose a lot.

I doubt that they intend to do quite as much as some are claiming. I suspect that all they are going to do is to integrate standard cells for the processor and graphics processor onto the same chip. Probably losing the FPU in the process and some other stuff that is not much use on a dedicated graphics machine - or at least not enough use to want to spend silicon on it.

The PC has been dancing close to the line where a PC on a chip becomes possible for some time. This has happened before of course, Inmos did it in the 1980s, but then you got 4Kb or Ram per transputer. Today you can get a CPU, Graphics processor and 2Mb of cache onto a chip without too much pain.

The costs of going custom are not that great for the production runs involved. We are talking tens of millions of chips. So the cost of some custom masks is really not that big of a problem. Microsoft hae to pay for the processor IP whether they use it as a standard cell or buy it in as a commodity.

The support chips will probably still be commodity items - but remember that there are a lot of things you just do not need on a game box that are vital for a PC, things like protected memory, virtual memory etc. They take up a lot of real estate but you don't need them in a game box.
