AMD Fusion, a CPU with onboard GPU brings competition to the Atom and in particular the Ion (Intel Atom+NVidia 16shader GPU). Unfortunately, and as with the Ion, most implementations tend to use moronically inferior heatsinks and fans and get deservedly poor reviews. The AMD-Fusion struggles to impress, but does manage an improvement of about 20% over the dual core Atom. In my experience these offer a cheap alternative PC, but the power saving is sometimes not there; I noticed no difference in power consumption between dual core Atom systems and IC2D’s from 1.6GHz through to 2.0GHz. Obviously the IC2D is more powerful in terms of performance but also costs a bit more.

Samsung pushing for Green 30nm RAM.
At CeBIT Samsung showed off the efficiencies of 30nm RAM over conventional 50nm RAM. A demonstration showed their 2GB modules to be 40% more power efficient and their 4GB modules to be 60% more power efficient . Heat was also reduced from around 59deg to around 53deg C and 50deg C respectively. At only a couple of Watts per module the running costs of RAM has little impact on the overall costs to home users, but in large server clusters and cloud computing the costs do add up and every saving helps. I would suggest the reduction in heat comes from leakage reduction, which would make these modules highly desirable amongst overclockers, should they ever hit the shelves. |
