MXM-spec3.0工业规范,The Mobile PCI Express Module (MXM) is a standard graphics interface for PCI Express® systems. This specification describes the electrical, mechanical and thermal interfaces for the MXM version 3.0 Graphics Module. MXM is the ideal solution where there is a need for low power, small form factor, high performance graphics adapter. Typical applications include notebook computers, blade and standard rack mount servers, mobile workstations and alternative form factor PCs including all-in-one, home theater and small form factor PCs. An MXM version 3.0 module is identified by its type (A or B). Each type has a distinct form factor and is aimed at different performance requirements and power consumption.

2. Functional Overview
2.1. Memory Interface
AMD Radeon E6760 has four DRAM sequencers, E6469 has two DRAM sequencers. Each
DRAM channel is 32‐bit wide. Four/two 32 Mb × 32 GDDR5 memory chips are embedded on
the ASIC for a total of 1G/512 MB Memory.
2.2. Acceleration Features
z
Fully DirectX® 11 compliant, including full‐speed 32‐bit floating point per component
operation:
z
Shader Model 5.0 geometry and pixel support in a unified shader architecture.
z
Support for OpenGL 4.1.
z
Support for OpenCL
tm
1.1
z
Anti‐aliasing filtering:
2x/4x/8x/16x modes.
Multi‐sample algorithm with gamma correction, programmable sample patterns,
and centroid sampling.
Temporal anti‐aliasing.
Adaptive anti‐aliasing mode.
Lossless color compression (up to 8:1).
z
Anisotropic filtering:
2x/4x/8x/16x modes.
Up to 128‐tap texture filtering.
Anisotropic biasing to allow trading quality for performance.
Improved quality mode due to improved subpixel precision and higher precision
LOD computations.
Advanced texture compression (3Dc+™).
High quality 4:1 compression for normal and luminance maps.
Works with any single‐ or two‐channel data format
