http://en.wikipedia.org/wiki/POWER7...Watson is made up of a cluster of ninety IBM Power 750 servers (plus additional I/O, network and cluster controller nodes in 10 racks) with a total of 2880 POWER7 processor cores and 16 Terabytes of RAM. Each Power 750 server uses a 3.5 GHz POWER7 eight core processor, with four threads per core. The POWER7 processor's massively parallel processing capability is an ideal match for Watsons IBM DeepQA software which is embarrassingly parallel (that is a workload that executes multiple threads in parallel)
POWER7 has these specifications:[6][7]
This gives the following theoretical performance figures (based on a 4.04 GHz 8 core implementation):
- 45 nm SOI process, 567 mm2
- 1.2 billion transistors
- 3.0 – 4.25 GHz clock speed
- max 4 chips per quad-chip module
- 4, 6 or 8 cores per chip
- 32+32 kB L1 instruction and data cache (per core)[8]
- 256 kB L2 Cache (per core)
- 4 MB L3 cache per core with maximum up to 32MB supported. The cache is implemented in eDRAM, which does not require as many transistors per cell as a standard SRAM[5] so it allows for a larger cache while using the same area as SRAM.
- max 33.12 GFLOPS per core
- max 264.96 GFLOPS per chip
Short answer: a lot.

The single thread performance of the chips is about equal to Penryn at the same clock speed.

Sort of the point, no?.....
The Jeopardy contest itself didn't seem anything special though. Sure the computer was powerful, but it was only winning because it could press the button faster(If I had the button that could be activated by my mind, and answers fed directly through my "circuits" I would have responded fast too).

That seem a little low for the units and cache the power7 sports?
I mean they quote 33gFlops per core. That's on par with sandy bridge AVX and about 7 times Penryn.

.... The point was to demonstrate AI capability. Response times don't tell that.
In other words, you can have a Watson in your house, but there probably won't be any room left for you.
This @ 4.5ghz would probably do it.
What is it anyway?
