The Nehalem architecture reduces atomic operation latency by 50% in an attempt to eliminate overhead on atomic operations such as the LOCK CMPXCHG compare-and-swap instruction. Lynnfield processors feature 16 PCIe lanes, which can be used in 1x16 or 2x8 configuration. 1 6500 series scalable up to 2 sockets, 7500 series scalable up to 4/8 sockets. Intel states the Gainestown processors have six memory channels. ↑ "Intel's dual teamed approached to micro-architecture development", PC Watch (in Japanese), January 29, 2008 · ↑ Botezatu, Bogdan (April 22, 2008), Intel: No Overclocking for Mainstream Nehalems, Softpedia ↑ "Feature - Intel Core i7 - Nehalem Architecture Dive".

However, this is only likely to be of real interest to users of rendering applications like 3ds Max, where accelerating performance can have a huge impact on using visualisation throughout the design process. N.B. There are actually two types of Xeon (Nehalem) processors, the Xeon 3500 Series and Xeon 5500 Series and it is only the Xeon 5500 Series that supports dual socket. In addition to offering a dual processor capacility, both the Xeon 3500 and 5500 Series supports ECC (Error Correcting Code) memory for better accuracy. The Nehalem architecture is a huge leap forward for Intel, introducing a number of new technologies, which not only improve efficiency in multi-threaded applications but enhance performance in single threaded applications. Alot has been happening in the world of processors over the past few months. The big news is that Intel has launched two new chip families based on the brand new Nehalem architecture, which represents one, if not the biggest architectural shifts in Intel processors for ten years. All Core i7 and Xeon 3500 / 5500 CPUs have four cores as standard, but they also feature a technology called HyperThreading, which simulates additional threads so each chip actually has eight logical cores. HyperThreading first came to market with the Pentium 4, but was abandoned for the Core 2. It uses spare CPU cycles on each physical core to simulate additional cores, and these can be seen when you bring up the Windows System Performance Dialogue. At the heart of this new architecture is a change in the way the chip accesses memory. Instead of the CPU communicating with the memory via the Front Side Bus, Core i7 and Xeon 3500 / 5500 can receive data directly from the system RAM.

But Nehalem promises more than just a performance boost: it is also more energy efficient than current designs. When the system switches off a processor core that is not being used to run an application, it can be turned off completely, without power "leaking" into it. Processors are struggling to run any faster, battery technology is improving very slowly and heat and power bills are problems for servers. If Nehalem delivers the promise of a balance between energy efficiency and improved performance it will mean users will not have to choose between low power and high performance when they buy a server or notebook. You don't get something for nothing, but Nehalem will let you choose between running more applications and having your battery last longer and when you only run a few apps you'll get better performance from them.
