Regardless of the D3D-like API-layer (which helped Microsoft compensate for the peculiarities of PowerPC), they're both PowerPC architectures.

You apparently don't know the Story how Sony spent big R&D-money with IBM to transition from MIPS to the custom PowerPC Cell Architecture, while IBM was already selling parts of this development to Microsoft for Xbox 360, and Microsoft ultimately beating Sony in market-launch with a chipset Sony partially financed...[0]

There's a nice book about it from two of the IBM Chip-Designers called "The Race for a New Game Machine" by David Shippy and Mickie Phipps

Nintendo also used PowerPC for GameCube, Wii and Wii U.

The PS3 system design was radically different. We considering porting the same PC game we (relatively) easily ported to 360 to that platform, but rejected it because it would be months of work, at least. Didn't matter that it was a similar CPU (technically) to the 360.

Microsoft was helped by PS 3 being a pain to program, given the Cell architecture, a mistake that Sony didn't repeat, and hence why the 360 was the only XBox that had an upper hand against Sony.
