Haswell to launch in March - June 2013

The latest Intel CPU roadmap has been seen at Donanimhaber, and shows that Haswell is currently expected to launch between March and June 2013. Using socket 1150, Haswell will be built using the same 22 nm production process as Ivy bridge. Interestingly, there is no sign of Ivy Bridge-E to replace Sandy Bridge-E for socket 2011 systems before the end of H1 2013, suggesting that SB-E may have quite an extended lifecycle.

Haswell will support DDR3 and DDR3L at 1600 MHz. it is expected to have a TDP of between 35W and 95W, and to run at faster clock speeds (with easier overclocking) than Ivy Bridge. The high TDP (Ivy Bridge has a maximum TDP of 77W) is possibly down to a more powerful iGPU (although this is unconfirmed).

There are conflicting reports about the performance and specs of the integrated graphics core. Known as the generation 7.5 graphics core, it is a minor upgrade to the graphics core used in Ivy Bridge. Ivy Bridge has up to 16 Execution Units (EU). Haswell has between 20 (VR-Zone) and 40 (SemiAccurate) 128-bit EU, with performance estimates ranging from 20% to 150% better than Ivy Bridge. Most sites refer to a graphics performance increase from Ivy Bridge to Haswell of somewhere in the region of 50%.

Update (February 14, by Gennadiy Shvets): Yesterday Donanimhaber posted another Haswell slide, that highlights major new improvements in the microarchitecture. The slide confirms many of originally reported features, such as enhanced overclocking, new AES and AVX instructions, integrated voltage regulator, support for three independent displays, LGA 1150 socket, memory configurations, and 35W - 95W power envelope. The slide does not have any new information about the microarchitecture.
