There are three "rails" of wattage in AMD's architectural plan for its CPUs: its higher-performance SE line, its lowest-power EE line, and its hybrid HE line that trades some performance for power savings. Two months ago, AMD introduced its first six-core Opterons in the SE flavor first, setting the general trend for future rollouts; last month, it trotted out the HE hybrid line in that same series. Today, as expected, the company is announcing stage 3 of its plan: the rollout of its first ultra-low-power six-core Opteron series, including the model 2419 EE, with 40 watts of average power consumption (ACP) clocked at 1.8 GHz. This time, AMD's value proposition is this: Server centers that already have quad-core 75W Opteron-based units can replace them for dropped in 40W six-core units, and see better performance per watt while gaining two cores per socket in the process. "We're still able to achieve up to 30% higher performance, as well as just above 30% higher performance-per-watt in that particular processor," stated AMD Senior Product Manager Brent Kirby in an interview with Betanews. Another formula that works to AMD's advantage in this demonstration: A rack with 24 servers, all using AMD's current line of six-core Opteron SEs at the 75W power range, could be traded for a rack of 42 servers using new six-core Opteron EEs at 40W, and stay within the same power envelope.
