This week, Gordon phones in from the IDF show floor, and the gang discusses Samsung's new Android phones, Intel's Sandy Bridge, AMD's Bulldog architecture, and the worst ships in the Star Wars universe.

You can’t say that AMD is ever boring. The company says its next-generation Bulldozer CPU core will take a unique approach to computing that goes beyond Hyper-Threading, which some believe could offer phenomenal performance.
Bulldozer makes a fairly big break from how today’s multicores are constructed. Today’s dual-, quad-, and hexa-cores are based on single-cores strung together. They can share L2 or L3 cache, but generally are partitioned off from each other. With Bulldozer, the basic building block of a multi-core chip changes from a walled off single core to more of a duplex. Two cores are tightly intertwined and share fetch, decode, floating-point scheduler, and dual 128-bit fused-multiply-accumulate units, or FPUs. AMD says each module includes dedicated integer schedulers, pipelines, and L1 cache.
This, AMD says, is far superior to Intel’s Hyper-Threading, which can bog down when the same resources are under load.
