So as to be able to compare IBM's revenues from Intel and Power server lines, I went back through IBM's press releases to get these numbers.

IBM Server News: Linux & Power8IBM is expected to announce at the Linuxcon 2013 conference in New Orleans, that it is pledging to invest $1bn in Linux and other open source technologies for its Power system servers. The company will also grow its Power Systems cloud, which lets developers remotely access Power, AIX, and IBM i gear on which to prototype, build, port, and test Linux apps.
IBM introduced its Power hardware to a world-wide audience on the game show Jeopardy where the Linux-based Watson supercomputer won.
The Power8 chip architecture has new technologies compared to its predecessors including the PCI-Express 3.0 protocol, shared memory and a new CAPI (Coherence Attach Processor Interface) for outside components to communicate with the CPU and other processing units. POWER8 is designed to be a massively multithreaded chip, capable of handling 96 hardware threads simultaneously.
IBM is building a Power Systems Linux Center in Montpellier, France, where developers will get access to Power chip and server technologies to develop and deploy Linux applications. The company already has similar centers in Beijing, New York and Austin, Texas.
The 22nm POWER8 chip, with its 96 hardware threads, is 650mm² and requires 200 watts. By comparison, next year's Intel 22nm Xeon chips are to have a die size of 100 to 200mm², 2, 4, 6 or 8 cores at two threads per core with the four core chip burning 45 watts. The 2.7Ghz 12-core chip draws 130 watts of power, and the 2.4Ghz Xeon draws 115 watts of power.
