I don't think it's actually that different, through not as easy to calculate as e did.
Quote, Wikipedia: "Titan has 18,688 nodes (4 nodes per blade, 24 blades per cabinet), each containing a 16-core AMD Opteron 6274 CPU with 32 GB of DDR3 ECC memory and an Nvidia Tesla K20X GPU with 6 GB GDDR5 ECC memory."
So it's pretty much standard hardware just a lot of it. Except that the graphics card is basically a consumer tesla with some extra juice, but it's still just a card built with what's possible today. Nothing extra fancy.
