Xbox 360: The Specs (X360)
We talk to Microsoft's Todd Holmdahl and get 100% official technical specifications.
By Bryn Williams | May 12, 2005


The last part of our Xbox 360 tour at Microsoft last week involved a brief meeting with Todd Holmdahl (corporate vice president, Xbox product group) who is personally responsible for the design, engineering, testing, and manufacturing of all Xbox consoles worldwide. Holmdahl went into some detail about the underlying architecture of Xbox 360, including a basic overview of the hardware, platform, services, and software, and how everything related to the core components of the system.

To accompany our visit, Microsoft furnished us with the final tech specifications for the console -- something which has long been the subject of much speculation across eager Internet fan sites and news groups. And it's also interesting to note that GameSpy's previous Xbox 360 article that broke earlier in the year at GDC 2005 was pretty much on the money in terms of the specs we'd been privy too.

Holmdahl then showed us some rather cool visual aids to help us understand a little better exactly how much hard work has gone into the engineering and design of the machine. We checked out the final mainboard of the 360, complete with a water-cooled CPU, GPU, and memory modules installed. It's pretty hard to comprehend the level of technology funneled into the 360 in light of its exceptionally cool form-factor; the internal guts of the machine are likely to set a new standard in efficiency of operation for modern-day video-game systems.

Along with seeing the final CPU, GPU, TV encoder, and Southbridge chips in the flesh, we were told how the CPU's three cores are capable of running at a whopping 3.2 GHz each -- each core supporting two threads making for a total of six threads running at any one time. The CPU is a custom-built IBM PowerPC-based chip. The GPU is also a powerhouse, and Holmdahl seemed confident that the graphical grunt of the 360 is around twice as powerful as the most powerful PC chipset architecture currently in circulation. With a clock speed of 500 MHz, the GPU (designed by ATI) is able to support up to 48 different pixel shaders (advanced shader language) at any one time, something which will allow developers and artists to use some truly gorgeous rendering and special effects in their games.

The CPU and GPU are linked together by a blisteringly fast data bus which can transfer operations at an incredible 5.4 Gb per second. Couple this together with the TV encoder chip (responsible for the various high-definition output modes that connect to HD-compatible displays) and the Southbridge chip which deals with a variety of functions like audio, and the core of the 360 shapes up to be incredibly efficient and extremely powerful. The bottom line? Games for the Xbox 360 have the potential to be very, very special. After all, the overall system floating-point performance of the machine is an astounding 1 TFLOP!

Wow, thtas alot of polygons... Most games only have around what?? Half of that?
X-Box's .... i forgot what its called.. Its a Driving Game.. the second one... Its cars use around 16,000 Polygons... and honestly how much would scenery take up...?

500 million triangles per second?
what is that? never heard that term

Thats Alot Of Nuts Triangles

Ya know...how do you guys learn about all this stuff...I read it and get so lost...all I know game counsils for, is playing them. I don't worry how much whatever they have. As long as it works and I can play games and have fun...what else do I need?

Many people think they know what they're talking about but truly do not.(not: not referring to anyone in particular).

We have like 5 Xbox 360 threads throughout the board lol.

Mrmenz...do you know anything about what they're talkin' about?

I hate when people make themselves look smarter than what they are (not refering to anyone in this thread), that kind of stuff makes me just feel dumb
I admit to what I know and dont know, lol.

But David...you know alot...

I understand most of it. I dont know the graphics side to it... but that is alot of triangles per second . Graphics is drawn in them , really small ones. But there not really triangles apparently... There apparently triangula pyramids .... Im going to bed...

< Was just on 666 posts #_o

Yeah, triangles are just the smallest and easiest-to-process polygons, having only 3 vertices. That's all.
