  • With a bit of magic, the GPU heat sink detaches from the logic board, exposing the AMD GPU.

  • The main chips on the GPU include:

  • AMD Radeon HD 6750M GPU

  • Four Hynix H5GQ1H24AFR T2L 1 Gb GDDR5 SDRAM chips (totaling a cumulative 512 MB)

拆解过程当中我们发现苹果的设计方案很独特。GPU 散热器从逻辑板上分离,露出 AMD GPU竟然是单独的。

GPU 上的主要芯片包括

AMD Radeon HD 6750M GPU

四个H5GQ1H24AFR T2L 1 Gb GDDR5 SDRAM 芯片(累计总计 512 MB)
