Inside a notebook battery pack review
Reviews The amount of energy needed to keep a notebook as warm as toast for four hours will melt steel if it's expressed in a few seconds -- and a damaged Li-ion battery can dump power that fast. One of eight in the example above, this contains about six...

Blades and business review
Reviews It's no coincidence that this is becoming an issue, now that both energy prices and supply are at their most unstable for a generation. Only in the last two or three years have more energy-efficient, server-oriented processors started to appear...

Fujitsu Siemens Primergy TX120 review
Reviews You may want to look elsewhere if raw computing power is your main concern, but you’ll struggle to find such a small-footprint, low-energy server that’s easy on both the eyes and ears. Fully loaded, the maximum active power consumption is 163 Watts...

Dell Latitude D505: a first look review
Reviews As with the Pentium M, the Celeron M will incorporate features designed to cut down on energy consumption, but it won't have as many. The Celeron M, for example, doesn't include Intel's SpeedStep technology, which allows the processor to slow down...

Intel Core 2 Extreme QX9650 review
Reviews They also generate less heat, since it doesn't need as much energy to do the same amount of work as a 65nm chip. That means it shouldn't be too long before Intel's new design trickles down to everyday PCs, and also that the processor market is due...

HP iPAQ H2210 review
Reviews As for differences, this iPAQ uses the 400MHz XScale processor instead of the allegedly more energy-efficient 266MHz Samsung chip, and you do get consumer-grade infrared, which allows you to turn the device into a programmable universal remote...

IDF: Banias fever breaks out review
Reviews To save energy, parts of the processor bus allow lower voltage swing and tight buffer management, resulting in lower power consumption by providing power only where it’s required. Furthermore, by using only 7 Watts to undertake this task, the chip...

Dell PowerEdge R710 review
Reviews A lot of work has also gone into optimising airflow and reducing energy consumption, making the R710 one of the coolest and quietest servers we've tested — only HP's ProLiant DL380 G6 bettered it in this respect.

IBM System x3455 review
Reviews Note, too, that slower chips are more energy efficient, enabling the x3455 to get by on just 95W compared to around 110W with the fastest processors installed. On the plus side, the two processor sockets are capable of accommodating a variety of...

Dell PowerEdge 1950 review
Reviews The review system came with Woodcrest chips fitted (now referred to as the Xeon 5000 and 5100 series), which are both faster and more energy-efficient than earlier Intel dual-core designs. The PE 1950 is very solid and well built.
