IDG News Service - Intel has added up to 15 cores in its latest Xeon E7 v2 family of server processors, but is stressing in-memory computing improvements with the latest chips.

The latest Xeon E7-4800 v2 chips, which are based on the Ivy Bridge microarchitecture, will be Intel's fastest server processors to date. The chips will go into high-uptime servers with up to 32 sockets, which typically handle enterprise applications such as databases, analytics tools and enterprise resource planning (ERP) software.

The new chips will have the most cores ever put in an Intel chip, and will boost server performance in a power-efficient way. Intel's Xeon E5 v2 server chips, which shipped in the third quarter, have 12 CPU cores. Advanced Micro Devices, which also ships x86 server processors, has a maximum of 16 cores in its chips.

Applications tied to in-memory computing such as databases will get a boost with new throughput features and memory capacity of 1.5TB per socket. The Xeon E7 v2 chips, code-named Ivytown, will run at clock speeds between 1.4GHz and 3.8GHz, and draw between 40 watts and 150 watts of power. Intel is shipping 20 new chips in that family with between two and 15 cores.

The new E7 chips are two times faster than their predecessors released last year, said Diane Bryant, senior vice president and general manager of Intel's Data Center Group, during a webcast.

There is a two-and-a-half-times increase in memory bandwidth, and the I/O capabilities have scaled up four times thanks to more data transfer lanes. Another new feature is support for the PCI-Express 3.0 protocol, which is already available on Intel's midrange Xeon E5 server chips. With support for multithreading, the 15-core Ivytown chip will be able to run 30 threads simultaneously.

The chips are targeted at sectors such as finance and oil and gas that need high-uptime servers and deal with large data sets to make real-time decisions, Bryant said.

Bryant provided the example of credit card companies using real-time analytics with social media information to identify fraud. For such tasks, high levels of processing and reliable servers are needed to generate real-time results, which is where the E7 v2 chips fit in, Bryant said.

Software from Microsoft, Oracle and SAP will take advantage of the processing and reliability features on the new server chips, Bryant said.

The chip also has 37.5MB in cache, which is an important performance booster. Data is transferred from processor to cache, and a large amount of cache will play a key role in boosting the performance of in-memory applications, said Dean McCarron, principal analyst at Mercury Research.

"When you have that larger amount of memory that close to the CPU, you get a significant performance boost from applications," McCarron said.

Rack servers with the new E7 v2 chips will have larger memory capacity, which will help process data and respond to queries quicker than predecessor chips, server makers said. Hewlett-Packard and Dell are among 21 server makers that are shipping or will announce products based on Intel's new server chip family.
