Quereis Ver como se desmonta la Xbox360

There are 48 shader units in the Xbox 360 GPU, but given that we're dealing with a unified shader architecture, you can't compare that number directly to the 24 shader pipelines of the GeForce 7800 GTX for example. We roughly estimated the power of the Xbox 360 GPU to be similar to that of a 24-pipeline ATI R420 GPU.

The other big feature of the Xbox 360 GPU is its dual die construction. The 332 million transistor GPU is split into two separate dice, the larger of which looks like a conventional GPU, and then a smaller die (aka daughter die) that is a 10MB block of embedded DRAM (eDRAM) combined with the hardware necessary for z and stencil operations, color and alpha processing, and anti aliasing. The daughter die connects to the larger die via a 32GB/s on-package interconnect.

The logic and embedded DRAM on the daughter die is what allows the Xbox 360 GPU to essentially offer "free" anti-aliasing, which Microsoft enforces through requiring developers to support a minimum of 2X AA in all Xbox 360 titles. Although we were originally told back at E3 that all Xbox 360 titles would support 4X AA, it seems that the statement has since been revised to 2X or 4X AA. We're not certain why the change was made, as 2X and 4X are both effectively "free" on the GPU, but there may be something we're missing.

Curioso el sistema de refrigeración.

En la foto del principio la fuente de alimentación me resulta monstruosa.

Uisss que ganas de desmontarla en casa a ver que sellos llevara de seguridad por eso.
