Santa Clara (ip-192.com): Intel announced the availability of its latest server processor, the Xeon 7500; shortly after AMD introduced its new Opteron 6000 server platform (ip-192.com reported here). Based on 45 nm manufacturing technology, the new eight-core processor series features 16 threads per socket and adds more than 20 new reliability features.
The quad channel integrated memory controller supports 1 terabyte of memory with 16 GB DDR3 DIMM’s in a 4-socket system and 2 terabytes in an 8 socket system.
Scalable Memory Interconnect offers up to 8 times the memory bandwidth of prior processor generations, Intel says. 24 MB of L3 cache increase the efficiency of cache-to-core data transfer rates. Latency is reduced by storing larger data sets closer to the processor. 64-bit guest OS-support is now possible, thanks to hardware enhancements that support virtualization.
High-speed point-to-point connections between processors allow transfer rates of up to 25.6 GB. Design changes help the new Xeon 7500 series of processors to perform up to three times better than the previous 7400 series, Intel says. The chips automatically monitor, report, and recover from hardware errors to maintain data integrity.
The new processors are available in 4, 6 and 8 core versions and carry price-tags from $856 to $3,692. Dell Inc. is one of the first manufactures to use the new Xenon 7500 in its server lineup, including rack mountable systems and blades. Cisco Systems Inc, IBM Corp, and Fujitsu Ltd have built devices using the new chips.
