rykter.. Xbox 2 spesifikasjoner


Prelude

Anbefalte innlegg

snublet over denne posten som viser noen seriøst syke spesifikasjoner for den nye Xbox'en som kommer.

 

Xenon is powered by a 3.5+ GHz IBM PowerPC processor and a 500+ MHz ATI graphics processor. Xenon has 256+ MB of unified memory. Xenon runs a custom operating system based on MS® Windows NT®, similar to the Xbox operating system. The graphics interface is a superset of MS® Direct3D® version 9.0.
CPU

The Xenon CPU is a custom processor based on PowerPC technology. The CPU includes three independent processors (cores) on a single die. Each core runs at 3.5+ GHz. The Xenon CPU can issue two instructions per clock cycle per core. At peak performance, Xenon can issue 21 billion instructions per second.

 

The Xenon GPU is a custom 500+ MHz graphics processor from ATI. The shader core has 48 Arithmetic Logic Units (ALUs) that can execute 64 simultaneous threads on groups of 64 vertices or pixels. ALUs are automatically and dynamically assigned to either pixel or vertex processing depending on load. The ALUs can each perform one vector and one scalar operation per clock cycle, for a total of 96 shader operations per clock cycle. Texture loads can be done in parallel to ALU operations. At peak performance, the GPU can issue 48 billion shader operations per second.

The GPU has a peak pixel fill rate of 4+ gigapixels/sec (16 gigasamples/sec with 4× antialiasing). The peak vertex rate is 500+ million vertices/sec. The peak triangle rate is 500+ million triangles/sec. The interesting point about all of these values is that they’re not just theoretical—they are attainable with nontrivial shaders.

Xenon is designed for high-definition output. Included directly on the GPU die is 10+ MB of fast embedded dynamic RAM (EDRAM). A 720p frame buffer fits very nicely here. Larger frame buffers are also possible because of hardware-accelerated  partitioning and predicated rendering that has little cost other than additional vertex processing. Along with the extremely fast EDRAM, the GPU also includes hardware instructions for alpha blending, z-test, and antialiasing.

The Xenon graphics architecture is a unique design that implements a superset of Direct3D version 9.0. It includes a number of important extensions, including additional compressed texture formats and a flexible tessellation engine. Xenon not only supports high-level shading language (HLSL) model 3.0 for vertex and pixel shaders but also includes advanced shader features well beyond model 3.0. For instance, shaders use 32-bit IEEE floating-point math throughout. Vertex shaders can fetch from textures, and pixel shaders can fetch from vertex streams. Xenon shaders also have the unique ability to directly access main memory, allowing techniques that have never before been possible.

 

 

uuuhhmm.... viss dette har to fnugg av sannhet over seg.. me wants! :dribble:

Håper da inderlig at dei held på konsoll-prinsippet og ikkje begynner å gjere dei oppgraderbare osv...

 

Ein konsoll, eit oppsett, mange spel som er garantert å fungere 100% til den konsollen. Det er sånn det skal væra.

bensinkanna, kanskje det, men hvor mange personer i dette lange land tror du har en pc med totalt 10.5Ghz rå prosessorkraft i 2006?

Det er forskjell på en 10,5ghz cpu og 3x3.5ghz. I 2006 blir det nok også mulig med mer enn 3cpuer på samme hk. Og vi skal ikke se bort i fra at vi sitter med 10,5ghz eller raskere cpuer i 2006.

 

Ontopic: zeph, har du lest at x-box2 kan bli oppgraderbare noe sted, eller er det bare spekulasjoner?
