Quad-core does more work per watt consumed

Lower power consumption means lower operating costs, and you can do so without sacrificing overall performance. Quad-core is leading the way toward optimizing the ratio of compute output to total power consumed. Quad-Core Intel® Xeon® processors use a similar amount of energy as single-core processors, while delivering dramatically improved performance:

• Decrease the power requirements of data centers and other facilities, reducing operating costs.
• Cut down cooling requirements, decreasing both day-to-day and capital costs.
• Deploy more compute capacity into existing server rooms, avoiding difficult and expensive facility upgrades.

Energy efficient computing

Quad-core Intel Xeon processors deliver a quantum leap in processing capacity and energy efficient performance, enabling businesses to grow their computing solutions more efficiently while helping to keep data centers cool. Since 2006, Intel quad-core processors have been providing the best performance available for mainstream servers. Now quad-core is available in all Intel Xeon processor sequences for systems ranging from entry-level 1-socket to ultra-scalable 32 sockets.

Quad-Core Intel Xeon processor 7300 series

Over 2x more performance/watt and up to 2x more performance³ and versus the previous dual-core Intel Xeon processor 7100 series processor. Supports more VMs and lowers TCO with the largest consolidation ratios of any Intel Xeon processor-based platform.

80-watt Intel Xeon processors set new standards in energy efficiency. The E7340, E7330, E7320 provide 15 percent up to 47 percent decreases in power.± For ultradense deployments the 50-watt Intel Xeon Processor L7345 provides 47 percent up to 67 percent decrease in power° from Intel dual-core 95- and 150-watt processors.

Intel quad-core includes power-efficient Intel® Core™ microarchitecture

Intel® Core™ microarchitecture enables very energy-efficient computing through a variety of power-conscious design features:

• Intel® Intelligent Power Capability throttles power to the processor's execution cores, powering up only those components that are needed.
• Intel® Wide Dynamic Execution enables delivery of more instructions per clock cycle to improve the efficiency of execution.
• Intel® Advanced Smart Cache improves performance and efficiency by increasing the probability that each execution core can access data from cache.
• Intel® Smart Memory Access increases efficiency by optimizing memory bandwidth and improving out-of-order execution.
