Haswell intels new processor like Ivy Bridge is expected to relese in next week.
Haswell is the codename for a processor microarchitecture to be developed by Intel's Oregon team as the successor to the Ivy Bridge architecture.[1] Using the 22 nm process,[2] Intel is expected to release CPUs based on this
microarchitecture around March to
June 2013 according to leaked roadmaps.[3] Intel has shown a working Haswell chip at the 2011 Intel Developer Forum.[4] According to Fudzilla, "Intel tells its partners to
expect that Haswell should end up
at least 10 percent faster than Ivy
Bridge based cores at the same clock."[5]Haswell will be the first processor to be designed from the
ground up to fully optimize the
power savings and performance
benefits from the move to 3D or tri-
gate transistors on the 22nm process
node. Improved graphics performance. Haswell is expected to
double the graphics performance vs.
Ivy Bridge processors bringing its
performance on par with the $50 -
$70 graphics cards. Technology Features carried over from Ivy
Bridge A 22 nm manufacturing process. 3D tri-gate transistors (Ivy Bridge processors and onwards). A 14-stage pipeline (since the Core microarchitecture).[6] Mainstream up to quad-core.[7] Native support for dual channel DDR3.[8] Confirmed new features Haswell New Instructions
(includes Advanced Vector Extensions 2 (AVX2) , gather, bit manipulation, and FMA3 support). [9] New sockets — LGA 1150 for desktops and rPGA947 & BGA1364 for the mobile market.[10] Intel Transactional Synchronization Extensions (TSX). [11] Graphics support in hardware for Direct3D 11.1 and OpenGL 3.2.[12] DDR4 for the enterprise/server variant (Haswell-EX).[13] Expected features Shrink PCH[14] from 65 nm to 32 nm. A new cache design. 128KB(64kB Instruction + 64KB
Data, 2 cycle) L1 cache and 1MB L2
cache(6 cycle) per core. Up to 32MB Unified cache LLC (Last Level Cache).[15] Support for Thunderbolt technology.[16] There will be three versions of the
integrated GPU: GT1, GT2, and GT3.
According to vr-zone, the fastest
version (GT3) will have 20 execution units (EU).[17] Another source, SemiAccurate, however
says that the GT3 will have 40 EUs [18] with an accompanying 64MB cache on an interposer.[19] An additional source, AnandTech,
agrees that GT3 will have 40 EUs,
but makes no mention of an interposer.[20] Haswell's predecessor, Ivy Bridge, has a
maximum of 16 EUs. New advanced power-saving
system. Base clock (BClk) increase to 266 MHz.[citation needed] 128 bytes cache line.[citation needed] Execution trace cache will be
included L2 caching design.[citation needed] Fully integrated voltage regulator, thereby moving a component
from the motherboard onto the CPU.[21] 37, 47, 57W thermal design power (TDP) mobile processors.[7] 35, 45, 55, 65, 77, and ~100W+
(high-end) TDP desktop processors.[7] 15W TDP processors for the Ultrabook platform (multi-chip package like Westmere).[7] Intel is developing a 10W TDP
processor for even greater battery
life, reduced heat which leads to
thinner as well as lighter
Ultrabooks. Due to reduced Watt-
usage the performance level won't be as strong as from the Ivy-bridge cpu at 17W.[22] Roadmap The main article for this category is Intel Tick-Tock. The Skylake microarchitecture will be the successor to the Haswell and
Broadwell architectures.
