AMD's 12-core "Magny-Cours" Opteron 6174 vs. Intel's 6-core Xeonby Johan De Gelas on March 29, 2010 12:00 AM EST

The Opteron 6176 looks a bit ridiculous as it delivers only 4% more performance at 30% higher power and 20% higher prices. The real reason behind this CPU is to battle another tanker, the Nehalem EX that Intel is going to launch tomorrow. The TDP and clockspeeds of that huge chip are very similar. If your application scales poorly and you don't care about power consumption, the X5677 is your champion; it is probably the fastest chip on the market for applications with low thread counts.

The most interesting parts that AMD offers are the dodeca-core 6174 (2.2GHz), the octal-core 6136 (2.4GHz) and the octal-core low power 6128 (2.0GHz). The 6174 targets those with well scaling multi-threaded applications such as huge databases and virtualized loads. The 8-core 6136 might even be better as most schedulers find it easier to distribute threads and process over a power of 2 cores. Lots of applications also don't scale beyond 16 cores and the chip comes with a 200MHz clockspeed bonus and a very reasonable price.
The 6128 HE is also an interesting one. The 6128 HE might be a good way to reconcile low response times with low power, but we'll have to find that out later.
