IBM's new Z13 mainframe is a hulking silicon beast. It packs the "world's fastest microprocessor," is twice as fast as most commercial servers, packs 300 percent more memory, and will be used for... shopping.

That's perhaps not too surprising given the size of the online shopping market. But this thing can sure handle the biggest of sprees: it'll chomp though up to 2.5 billion transactions per day, analyzing each one in real time so it should (hopefully) catch someone who's using your card fraudulently before they'e actually bought anything. You'll probably never know that Z13 is taking care of your purchases‚ÄĒbut it might just save you some stalled transactions. [IBM]
