IBM develops processing chips for gaming consoles. The Xbox 360 contains IBM's tri-core chipset Xenon. At the request of Microsoft, IBM was able to design the chip and ramp up to production volumes in less than 24 months (with co-production at Chartered Semiconductor Manufacturing in Singapore.)[30] Meanwhile, Sony's PlayStation 3 will feature the Cell, a new chip designed by IBM, Toshiba, and Sony in a joint venture. The Cell is already slated for use in other systems (Toshiba plans to use it on HDTVs), unlike the Xbox 360 chip, whose plans are owned by Microsoft. The Wii will, like its predecessor, the GameCube, feature an IBM chip (codenamed Broadway).
In May 2002, IBM and Butterfly.net, Inc. announced the Butterfly Grid, a commercial grid for the online video gaming market.[31] In March 2006, IBM announced separate agreements with Hoplon Infotainment, Online Game Services Incorporated (OGSI) and RenderRocket. The deals included on-demand (for Hoplon Infotainment and RenderRocket) and blade servers (for OGSI).
Comunque a tuttoggi ibm non è supportata da microsoft quindi possiamo pure scordarcelo perchè:
1) E' una vana illusione poter pensare di poter usare cell per videogiocare (a meno della ps3)
2) I programmi non sono ottimizzati per i dual core, pensiamo per un 7^ (ps3) o un 9^ core
3) il prezzo decisamente improbo di tali architetture
