Haswell is the codename for a processor microarchitecture to be developed by Intel's Oregon team as the successor to the Sandy Bridge architecture.[1] Haswell will use a 22 nm process.[2] CPUs based on the Haswell microarchitecture are expected to be released in 2013, approximately one year after the March-April 2012 release of Ivy Bridge, according to Intel's Tick-Tock strategy. Intel showed a working Haswell chip at the 2011 Intel Developer Forum.[3]
Technology
Features carried over from Ivy Bridge:
- A 22 nm manufacturing process.
- 3D tri-gate transistors (for Ivy Bridge processors and onwards).
- A 14 stage pipeline (since the Core microarchitecture).
Haswell is confirmed to have:
- Advanced Vector Extensions 2 (AVX2) instruction set (or Haswell New Instructions), including gather, bit manipulation, Floating Point Multiply Accumulate, and FMA3 support.[4]
- Direct3D 11.1 and OpenGL 3.2 graphics unit.[5]
Haswell is expected to have:[2]
- A new cache design.
- New advanced power-saving system.
- Up to 2~6 cores available in consumer market and 10 core in server version.
- 1MB L2 cache per core and up to a 32MB L3 cache for the Extreme Edition and Xeon.[6]
- 95W TDP 10-core EP chips.[7]
- New sockets - LGA 1150 for desktops and rPGA947 & BGA1364 for the mobile market.[8]
- Fully integrated voltage regulator, thereby moving another component from the motherboard onto the CPU.[9]
- Thunderbolt technology.[10]
- Support for hardware-based transactional memory.[11]
- 15W TDP processors for the Ultrabook platform (multi-chip package like Westmere).[12]
- 37, 47, 57W TDP for mobile processors.[13]
- 35, 45, 65, 95W TDP for desktop processors.[13]
- Integrated GPU up to 20 EUs.[14]
Broadwell
In keeping with Intel's tick-tock principle, the 14 nm shrink of Haswell is due out the year after the introduction of the microarchitecture and will be codenamed Broadwell.[15][16]
It is said to become the chip maker’s first true system-on-a-chip (SoC) design.[17]
Successor
The Skylake microarchitecture will be the successor to the Haswell and Broadwell architectures.
