Haswell is the code name for a processor that is being developed by Intel and is the planned successor to Sandy Bridge. Haswell will be designed for the 22 nm manufacturing process, introduced with Ivy Bridge, and is planned for a commercial release in 2012. Haswell should be the first Intel x86-64 CPU to implement FMA (Fused Multiply-Add also known as Multiply-accumulate) instructions.[1] Haswell's design is in the early stages of development. Like Nehalem, Haswell is being developed by Intel's Oregon team rather than by Intel's Israel Development Center like Core and Sandy Bridge.[2] One tech journalism site claims that Larrabee graphics capabilities will be integrated in the Haswell microarchitecture. [3]
Architecture
Haswell is expected to have the following features:[1] [1]
- Possibly completely redesigned microarchitecture, like NetBurst was after P6
- 22 nm process
- 8 cores by default
- Entirely new cache design
- Revolutionary power saving systems
- Possible on-package vector coprocessors
- The addition of fused multiply-add instructions
- Possibly a one-year transition from Sandy Bridge[citation needed]
