On the technology side, Nehalem EP's integrated memory controller isn't new to the industry. Intel rival Advanced Micro Devices was the first with an on-chip controller in its 2003 Opteron server processors. While Intel has played down the need for the technology in the past, it's obvious that the demands of computing today have made the need for the higher-performing architecture pivotal.
Other important features within Nehalem are very sophisticated management of multithreading and of the multilevel caches. In addition, the architecture includes more advanced power management technology that computer manufacturers can tap into to reduce a system's energy consumption.
The Nehalem variant, known as Core i7, for high-end desktops and workstations was launched late last year.
