Intel Xeon E3-1280

The Quad-Core Intel Xeon E3-1280 processor is based on the Sandy Bridge architecture. The CPU is optimized for motherboards and ideal for server, workstation and storage systems. The clock rate of the 4-CPU cores in each case is 3.5 GHz (Max Turbo Frequency: 3.9 GHz) and offers a transmission rate of 5 GT/s (gigatransfer per second/DMI). The Intel Xeon E3-1280 CPU supports Hyper-Threading and therefore is able for 8 simultaneously threads processing. The maximum power consumption is 95 W TDP. The Intel Xeon E3-1280 supports DDR3 ECC memory modules with a clock speed of up to 1333 MHz and dual-channel.
