New Xeon for dual-processor ProLiant G6

Since the end of March, HP began shipping 16 models of ProLiant G6 dual-processor servers (rack-mount DL160, DL170h, DL180, DL320, DL360, DL380, tower ML330 and ML350, blades BL280c, BL2 × 220c, BL460c and BL490c, as well as three compute modules BL280c, BL2 × 220c, BL460c and BL490c, as well as three compute modules BL280c, BL2 × 220c, BL460c, and BL490c, as well as three compute modules BL280c, BL2 × 220c, BL460c, and BL490c, as well as three compute modules BL280c, BL2 × 220c, BL460c, BL460c and BL490c, as well as three compute modules BL280c, BL2 × 220c, BL460c, BL460c, and BL490C. blade-workstation WS460c), in which the new Intel Xeon 5600 from the Nehalem series (codename Westmere EP) is installed.

Thanks to the transition from 45-nanometer technology to 32-nanometer Intel managed to increase the number of processor cores from four in the Xeon 5500, which was released about a year ago, to six. If we consider that each core of Westmere EP using HyperThreading can simultaneously execute two streams of commands, the performance gain of a two-processor server will be four additional streams of commands. In addition, the built-in cache Xeon 5600 and a half times more than the Xeon 5500.

By the way, both generations of Nehalem are fully compatible with the connectors, which means that the owners of the ProLiant G6 released a year ago can now upgrade the server by simply replacing the processors (along with installing a new BIOS version) and as a result, increase the power of their machines by 1.5 times. But it is better to buy a whole new server :)

But seriously, the new processor is a lot of waste. Tell me, is the performance increase he promises, so that you decide to upgrade?
