That's not true. IBM's fab has 100% yields. Sony is the one making
the loose acceptance through less utilization model. Even Toshiba has a
100% yield Cell fab line.

The 100% chips were too expensive,

No. Testing for 100% and only incorporating a fully functional CPU into
your system is "too expensive"... for a consumer product... from
Sony's POV.

See links above.


Hell, the friggin' PS3 has thermal problems at the CPU cite even with
one less SBE.

Not anything like the Microsoft console 'red ring of death'.
Actually there are newer versions of PS3 with a new cooling system in the make:
