The revolutionary Xeon 5400 chip - the first based on its Penryn technology - was announced yesterday to power servers that will deliver significant performance and power consumption benefits across a wide range of low latency financial applications, including risk analytics, market datafeed handling and transactional execution systems.

Penryn - characterised by Intel co-founder Gordon Moore as the biggest transistor advancement in 40 years - incorporates so-called Hafnium-based High-k Metal Gate transistors, and 45 nanometre transistor packaging, allowing chips to be built with nearly twice the transistor density as current models (which use 65 nanometre packaging). This equates directly to being able to deliver more compute power for the same amount of electrical power consumed.

The 5400 chip (previously known by its codename, Harpertown) also includes a 12 megabyte cache and a 1600 MHz front side bus to boost input/output bandwidth. The chips will be incorporated into the Stoakley platform, which will form the basis for commercial server products.
