# CPU - Xenon's CPU has three 3.0 GHz PowerPC cores. Each core is capable of two instructions per cycle and has an L1 cache with 32 KB for data and 32 KB for instructions. The three cores share 1 MB of L2 cache. Alpha 2 developer kits currently have two cores instead of three.

# GPU - Xenon's GPU is a generation beyond the ATI X800. Its clock speed is 500 MHz and it supports Shader 3.0. Developers are currently working with an alpha 2 GPU. Beta GPU units are expected by May and the final GPU is slated for a summer release. The final GPU will be more powerful than anything on the market today; in game terms, it would handle a game like Half-Life 2 with ease.

# System Memory - Xenon will have 256 MB of system RAM. Keep in mind that this number should not be equated to typical PC RAM. The Xbox has 64 MB of system RAM and is a very capable machine.

# Optical Drive - As many have speculated, Xenon will not use Blu-Ray or HD-DVD. Games will come on dual-layer DVD-9 discs. While the media is the same as that of the current Xbox, the usable space on each disc is up to 7 GB. The drive is slated to run at 12X.

# Memory Units - Xenon will use 64 MB to 1,024 MB memory cards. 8 MB is reserved for system use, leaving a 56 MB to 1,016 MB for user data.

# Hard Drive - As many have speculated, Xenon's hard drive is optional. 2 GB of the drive will be used as game cache. The final drive size is still being determined.

# Camera - Xenon will have a USB 2.0 camera. It's capable of 1.2 megapixel still shots and VGA video. Photos can be used in-game and for gamer profiles. The camera can also be used for video chat. It's unknown if the Xenon camera will allow for EyeToy-like gameplay. Developers are currently using a simulated camera driver.

# Sound Chip - Xenon does not have an audio chip in the traditional sense. Decompression is handled by hardware, while the rest of the chores are handled by software. DirectSound3D has been dropped in favor of X3DAudio. The former was deemed too inflexible.

The Xenon is an extremely impressive piece of hardware. It will allow gamers to see things like complex lighting in gameplay, amazing details through high-level shading (impeccable clouds, fur, grass, cloth, water, marble, ground, etc.), incredible textures, and new post effects (increased motion blur, heat distortion, depth of field, light blooms, etc.).

While people have already been correctly speculating about the removable hard drive and the standard DVD media, I was surprised at the inclusion of the camera. I haven't heard a single rumbling about a Xenon camera prior to GDC. The optional hard drive is a bit understandable; the only gamers that care about it will buy it anyway, while casual gamers won't care about the performance and convenience gains a drive offers. The standard DVD isn't too surprising considering that HD-DVD drives will be too expensive for inclusion in a console system in 2005.

The Software

Microsoft is requiring developers to make all Xenon titles Live enabled. One of the key reasons for this will be revealed in the second part of this story.

Developers are being instructed to plan their games for high-definition. The baseline is 720p at 1280x720 for gameplay and video clips, 16:9 aspect ratio, 5.1 Surround Sound, and anti-aliasing. These features are the current minimum requirement.

All Xenon games can be played using custom soundtracks. Owners can also play their own music directly. Supported formats are MP3 and WMA. Files can be encoded up to 320Kbps CBR or VBR stereo. The system is branded a Music Player Service.

For gameplay movies, Xenon uses Xenon Motion Video (XMV). XMV is based on Windows Media 9 and uses the mandatory codec for HD-DVD. The goal for video is 720p running at 30 frames per second with 5.1 Surround Sound.

Raymond's Reaction - Mandatory Live "awareness" isn't a big surprise. Online is one area where Microsoft is trouncing the competition. Microsoft's progression with online console gaming has progressed wonderfully (see Halo 2) and the future plans are even more interesting. (Again, see part two of this feature tomorrow for more information.)

It's nice to see that Microsoft is being aggressive with HD performance. Having all games run at 720p (potentially) makes for an incredibly engrossing experience -- particularly owners of HDTV sets. Users with standard televisions needn't worry; 16:9 content will be letterboxed to fit within a 4:3 aspect ratio by default. Developers are being instructed to make sure that any critical text will fit into and look good in 4:3.

Si la console sort à la fin de l'année, elle va leur couter une petite fortune à sortir parce que la X800 et un processeur à 3Ghz avec 2mo de cache, c'est pas ce qu'il y a de moins chère.

Pour l'absence de HD, c'est purement pour empecher la copie de jeu.

C'est plutôt pour réduire le coût de la console puisqu'il y aura une version avec un disque dur.

Regardez les specs des computers de n'importe qui sur ce forum... et dites vous que les consoles new-gen seron 3fois plus puissantes

Y me semble qu'on fait un TRÈS gros bond tout d'un coup! Je veux dire, les specs de la PSX par-exemple ne sont pas siiiii loin que ça des specs de la PS2 quand on y pense bien... et là tout à coup comme ça on est rendu avec des machines à plusieurs processeurs

On dirait qu'on a fait un bon de 5ans en 6mois

Faudra voir à combien ils vont la vendre. Mais quand on voit comme le HD sur la PS2 sert à rien, je suis pas sur que se soit une bonne idée de sortir plusieurs versions différentes d'une console. Car en plus de meler l'acheteur, sa complique la vie aux équipes de dévellopement.

J'ai comme l'impression qu'ils vont encore la vendre à perte

c'est pas nouveaux, et microsoft sont pas les seuls a le faire a ce que je sache.

et c'est tant mieux
