Advanced Micro Devices and Intel this week took the wraps off new energy-efficient processors aimed at reducing power consumption in data centers and computing environments.
AMD announced the availability of the AMD Phenom X4 9100e, 65-Watt Quad-Core processor for desktop PCs.
By coupling an AMD Phenom X4 9100e with an AMD 780 series chipset, users can perform multitasking capabilities like creating digital content while checking and writing e-mails and simultaneously downloading music files off the Web, AMD officials said.
Some of the AMD energy-efficient innovations in into the processors include:
- Cool'n'Quiet 2.0 technology;
- CoolCore, which helps users achieve more efficient performance by dynamically activating or turning off parts of the processor as needed;
- Independent Dynamic Core Technology, which adjusts power usage according to core utilization;
- Dual Dynamic Power Management;
- Wideband Frequency Control, which helps reduce power consumption, latency and software overhead of performance state changes; and
- Multi-Point Thermal Control, multiple sensors across processor silicon designed to reduce speed and heat when temperature exceeds predefined limits.
Meanwhile, Intel introduced two low-voltage, 45-nanometer processors for servers and workstations that run at 50 watts and frequencies as high as 2.5 GHz.
The Quad-Core Intel Xeon L5400 processors are geared for organizations with power-constrained, high-compute-density environments. They are 25 percent faster and have a 50 percent larger cache size than Intel's previous-generation, low-voltage Quad-Core Intel Xeon processors.
The quad-core L5420 and L5410 processors run at 2.33 GHz and 2.5 GHz, respectively.
A number of vendors are supporting the L5400 series and L5210, including Asus, Dell, Fujitsu, Gigabyte, HP, Hitachi, IBM, Microstar, NEC, Quanta, Rackable, Supermicro, Tyan and Verari.
Next quarter, Intel will also begin shipping the L5210 dual-core processor with a 40-watt rating and clock speed of 3 GHz, Intel officials said.
