Aside from that other little announcement out of Cupertino, one of the worst-kept secrets in the tech world was the impending release of Intel's successor to its vaunted Xeon 5600 series processors--the chip that's currently the power plant for the cloud. The new E5's Sandy Bridge micro architecture is well known as it debuted on Intel's desktop and laptop lines over a year ago, and its successor, the Ivy Bridge generation, will show up on consumer devices in a couple months. Formerly known as the Sandy Bridge-EP, the new E5-2600 series chips further cement Intel's preeminence atop the processor landscape. Here are a few reasons why.
1. More Power Scotty. Not only does the E5-series increase the top Xeon core count by a third, from 6 to 8 per chip, it almost doubles the L3 cache from 12 MB to 20 MB at only a slight loss in clock speed. The 8-core part tops out at 2.9 GHz. Intel claims these combine to yield an 80% performance improvement and they have a slew of benchmarks to back up the claim. While we hold a skepticism toward benchmarks that would make Mark Twain proud, this is an impressive list with 13 records for two-socket systems and two overall records for system-level energy efficiency (workload/watt).
