I checked the abstract again and all the numbers are correct. Here it is: "The Intel 32nm Poulson processor contains 3.1 billion transistors integrated onto a single 544mm2 silicon die size. Eight processor cores and a total of 54MB of on-chip cache are linked by an on-chip ring-like interconnect bus."

I calculated 2.7B instead of ~2.6B because I used 1MBit=1024*1024=1.049 million cells. Either way it does not make too much difference. For comparison, the 45nm Xeon 7500 (aka Nahalem-EX) had 2.3B transistors and a total of 26.5 MB of cache which leaves about 1B for other things, much more reasonable.

It is interesting that a simple CPU captures our imagination at the same time that an extremely complex one is rolling out. I suspect that it is because small numbers are easier to grasp than large ones - and because we can appreciate that a device built with simple materials and a simple architecture has the potential to be incorporated in unexpected ways in existing products.

@pixies, Polymer is a solid state material, although it is not semicondcutor so everything is good with the ISSCCC name! BTW, everything can be a solid state (if the temperature is right ;-) so they selected pretty general name...Kris

@bmws88, you seem to be right, something is not adding up here: 54MB times 8 times 6 is about 2.6B transistors already...Kris

Intel uses 8T SRAM for lower level cache. Assuming all 6T, 54MB of cache would have a SRAM cell transistor count of 2.7B already. That leaves only 0.4B for redundancy, cache peripheral, and the 8 cores. Do the numbers add up right?

Polymer is not a solid state material. I guess in the future the conference has to change its name.

What is this polymer CPU is all about. Really curious to know how it functions and how it will be useful in future. Anybody has any detailed info ?

So many different variants are going to flood the market, but the polymer CPU is something very interesting, it seems that the flexible and fold-able PCs will be there in a near future.
