Did a little searching. The Conroe chip has 290 million transistors. I found the following on some webpage:
It turns out that the Xbox 360 GPU which is now known as 'Xenos' (not R500 anymore) is an absolute friggin monster. the GPU package contains two seperate dies. the total amount of transistors for the entire GPU-system is 332 million. the main 'parent' GPU has 232 million transistors. the "daughter' die, which contains the eDRAM plus other logic for z-check, anti-aliasing, and other stuff, has the other 100 million transistors.
this is a DAMN SIGHT more than previously reported. on May 12th, IGN reported that the Xbox360 GPU had 150 million transistors. this was very surprising, given that, ATI's 1+ year old R420 (Radeon X800) had 160 million.
but *now* that it has been revealed that Xbox GPU 'Xenos' has an 332 million transistors, it can be said that this graphics architecture surpasses Nvidia's RSX 'Reality Synthesizer' GPU in Playstation3, which only has 300 million transistors. it seems Microsoft and ATI have built a real beast of a GPU here.
here is the article confirming Xbox360 GPU graphics subsystem has 332M

Note that the X-Box systems have integrated video cards, and memory controlers, and all that jazz. They're counting EVERY transistor on the entire system, whereas on my desktop PC I have N1 transistors in my CPU, N2 transistors in my graphics card, and N3 transistors in my Audigy sound card.
If I've got a Conroe (which I will soon) I'd have 290M transistors. ATI estimates the RV570's transistor count at 330 million (RV570 used in the x1950 card). my Audigy card is supposed to have 4.6M transistors...
So, my desktop PC could have 624M transistors for a mid-range system. Whereas the highest of the best of the X-Boxes has only 332M.
There's no way an X-Box of any make or design will best any of the high-end desktops. It just can't happen, due to the integrated nature of the X-Box design, and the modular design of existing desktops.
