Recently i have started to learn about processor architecture especially Intel Nehalem Architecture. Nehalem is Intel's new processor microarchitecture, which scalable with future versions having 2 to 8 cores, features with Simultaneous Multi-threading, resulting in 4 to 16 thread capabilities. With up to 8 MB level-3 cache, 731 million transistors, Quickpath interconnects (up to 25.6GB per second), integrated memory controller and optional integrated graphics, which will deliver 4 times the memory bandwidth compared to today's highest-performance Intel Xeon processor-based systems . In some ways, Nehalem is Intel's most significant processor since the Pentium 4
The future processor is Haswell. Haswell will be designed for the 22 nm manufacturing process, was introduced with Ivy Bridge, and was originally planned for a commercial release in 2012.
Haswell is expected to have the following features:
- Possibly completely redesigned microarchitecture
- 22 nm process
- 8 cores by default
- Entirely new cache design
- Revolutionary power saving mechanisms
The processor has not been confirmed to be in development.
