About this component
The APU holds both the CPU and GPU and talks directly to the 8 GB of GDDR5. Six of the eight cores are available to games. APU failures (often shown as the 'blue light of death') are usually solder-ball or substrate problems that need BGA rework or a donor board; APUs are paired with the board's secure data, so a straight swap from another console is not straightforward. Part variants: CXD90026G on CUH-10xxA; CXD90026AG on CUH-11xxA. CXD90026BG and CXD90037G are also listed by psdevwiki, probably for later CUH-11xx/12xx boards, but the mapping is not confirmed.
What it does on this board
8-core Jaguar CPU @1.6GHz with an 18 CU GCN GPU (~1.84 TFLOPS).
