AMD working on low-power Adelaide server platform

Later this year AMD will introduce Adelaide, a 2-way server platform that focuses on energy efficiency. The platform will feature six-core Lisbon processors, the AMD SR5650 chipset (22 PCIe lanes, 9.6W TDP in low-power HT1 mode) with AMD SP5100 input/output controller. Adelaide will stick with HyperTransport 1, but will feature the 1.6GHz Opteron 4160 EE and 1.5GHz Opteron 4158 EE, chips that reportedly have a power consumption of only 35W, significantly less than current Opteron EE chips.
But the low power consumption of Adelaide will come at a price: if the next-generation Maranello and San Marino platforms will feature HyperTransport 3 links, then Adelaide will have to rely HyperTransport 1 instead in order to reduce consumption of both CPUs and core-logic sets. Just like the code-named San Marino, AMD Adelaide will support up to six memory modules per socket, however, it will not support fast DDR3 modules, but will work with low-voltage DDR3 at the speeds of up to 1066MHz.

AMD’s energy-efficient six-core Opteron microprocessors will feature 3MB of level-two cache (512KB per core), 6MB of level-three cache, two HyperTransport 1 links and dual-channel DDR3 memory controller that supports up to PC3-8500 (DDR3 1066MHz) memory in addition to low-voltage DDR3 and quad-rank DIMMs.
