AMD Magny-Cours 12-core Opteron 6174 vs. Intel 6-core Xeon

AMD's offering today is very different; “Magny-cours” is the CPU version of the American muscle car. It's a brutally large 12-core CPU: two dies, each measuring 346mm2 connected by a massive 24 link Hyper Transport pipe. AMD's Magny-cours Opteron has almost two billion transistors and 19.6MB of cache on-die. It's not all raw horsepower though. […]

AMD's offering today is very different; “Magny-cours” is the CPU version of the American muscle car. It's a brutally large 12-core CPU: two dies, each measuring 346mm2 connected by a massive 24 link Hyper Transport pipe. AMD's Magny-cours Opteron has almost two billion transistors and 19.6MB of cache on-die. It's not all raw horsepower though. At 2.2GHz this 12-core monster is supposed to be content with only 80 precious watts, and 115W at most. HT assist also makes an appearance to keep CPU-CPU accesses to a necessary minimum, a problem that could get out of hand with 12 cores otherwise. AMD originally added HT assist with its first 6-core Opterons. So Magny-Cours is a like hybrid V12 Dodge Viper with traction control. Will this cocktail of raw core muscle and energy savings be enough to beat the competitor from Portland the Intel Xeon X5670 Westmere EP?
