According to Intel, Nehalem is a truly dynamic- and design-scalable microarchitecture. It will deliver both performance on demand and optimal price/performance/energy efficiency for each platform.
Nehalem's dynamic scalability includes:
- Dynamically managed cores, threads, cache, interfaces, and power
- Leveraging leading 4 instruction issue Intel Core microarchitecture technology (Intel Core microarchitecture's ability to process up to 4 instructions per clock cycle on a sustained basis as compared to 3 instructions per clock cycle or less for other processors)
- Simultaneous multi-threading (Intel Hyper-Threading Technology) to enhance performance and energy efficiency
- Innovative new Intel® SSE4 and ATA instruction set architecture additions
- Superior multi-level shared cache that leverages Intel® Smart Cache technology
- Leadership system and memory bandwidth
- Performance-enhanced dynamic power management
Nehalem's design scalability will enable optimal price/performance/energy efficiency for each market segment through:
- New system architecture for next generation Intel processors and platforms
- Scalable performance for from one-to-sixteen (or more) threads and from one-to-eight (or more) cores
- Scalable and configurable system interconnects and integrated memory controllers
- High performance integrated graphics engine for client platforms
