| Re: OT: XBox 2, 3, and so on | |

In Response To: OT: XBox 2, 3, and so on (TCB) IF Xbox 2/3/... were to use an architecture which used the same bytecode (i.e., the continued to use x86), it would be beyond easy to maintain this kind of backward compatability. However, the real reason I chimed in here is to point out -- yet again (I feel like I have to say this every 3 seconds, since no one gets it) -- that the xbox is architecturally very different from a PC. It uses PC-derrived hardware, but so, to a certain extent, does the Game Cube, insofar as both use CPUs based on the same instruction sets as major PC platforms. However, not only are the graphics chip and system architecture *not* at all like those in any PC (the SGI VW320/540 series workstations for 1999 were the most similar in the PC world, in most respects, based on a unified memory architecture where the -graphics chip- was make the center of the system by merging it with the central i/o paths/logic), with the only relationship being the graphics core's architectural foundations in the NV2x base design. What no one seems to realize is that the CPU isn't even anything like an off-the-shelf PIII. It is a P6 core (which even the PPro was, but who would claim the PPro and the PIII were the 'same chip'?!?), and placing it even closer to the PIII, it does have MMX/SSE. However, it has a TOTALLY different FSB (which is a very significant aspect of the CPU, from an architectural standpoint), and much more cache, and I believe even has a different cache configuration (which is a HUGE difference). As a whole, the xbox is derived from PC hardware architectures because they are the most well understood and widespread -- and so have the largest selection of, and best, development tools, which are the most familiar to the largest number of existing developers. But does anyone claim the Game Cube is an iMac or some bullshit, because it uses a PowerPC 750 derivative for its CPU, and a future ATI chipset architecture for its graphics, which will be rolled into the ATI retail market at some point? No. In both respects -- the cpu and the graphics -- it is in a position identical to the xbox, but because the xbox has the microsoft and intel (and nvidia) names on it, everyone says it's just a PC. Sorry, ;) | |
