When talking about the "Fusion" project, AMD's Giuseppe Amato notes that implementation as a multi-chip module might be interesting for AMD

This article was first published in German on

In the press session about AMDs K10 architecture Guiseppe Amato also gave some additional info on the AMD Fusion project. He explained that it is very possible, that Fusion products might come in the form of multi-chip modules, also known as MCMs.

Amato noted, that multi-chip modules are more flexible in comparison to single dies. He gives a very simple example. To paraphrase, Amato says AMD could ship a CPU with integrated DX10 graphics functionality. Once DX11 comes out,  AMD would have to do a complete chip redesign. When implemented as a MCM, the company can keep the CPU part as is and just exchange the graphics core for a new one – all implemented on a single package.

Integration into the main silicon die only makes sense, if the functionality doesn't change for a at least a year. Ironically, efficiency advantages were always touted by Intel when talking about their MCM implementations of dual- and quad-core CPUs. However, AMD adds one interesting factor, a partial upgrade of a product with the other chip left untouched.

really, a single chip is cheaper for a consumer.

why? well, when a whole new dx comes out, the cost of a chip that is 50%-100% more powerful for general use is also out and probably costs less than the first chip when you bought it.

If my 4200+ 939 chip had dx9 on it, then the next chip of the same price, namely, the 3.0ghz am2 chip would blow it away and be worth the price.

I might be getting this fusion idea wrong but... fusion is when all things are stuck together. multi chip ='s same shit different day. only thing that it does it make things proprietary and sluggish.

I think you misunderstand both fusion and multi-chip modules.

Fusion is AMD's tech for placing coprocessors (inlcuding GPUs) in cpu sockets on multi-cpu motherboards to take advantage of the very high speed, low latency interconnect available to the socket.

Multi-chip modules are single packages with multiple die in them. In this case, they are talking about putting a CPU and the coprocessor in a single package, much like the QX6600 has two Conroe die in it. It is a single chip as far as the end user is concerned, and is exactly what you were talking about as a good thing with your 4200+.

Imagine a MCM CPU that you could swap out Co-processors, Physix, GPU, and vice versa depending on your usage!

That would be very cool.

If they do it right, you could have a stackable setup with all three.

Only issue then is how to cool the bugger...???

They would have to have a Card Slot format with multiple sockets like the old AMD Athlons, P2's and P3's..
