Intel CPU roadmap Ivy Bridge (microarchitecture)

Complete Ivy Bridge line-up is leaked on Intel website

Intel has many new products lined up for the launch in the next few months, including desktop, mobile and server Ivy Bridge processors, and numerous Xeon Sandy Bridge EP models. With the sheer number of upcoming products, it's not surprising that details of some of them are leaked not just by partners, but by the Intel themself. One day ago during routine Google search we spotted a flipbook PDF file, titled New 3rd Generation Intel Core Processors(11MB PDF file). The PDF file is open to public, and contains full line up of desktop and mobile microprocessors for January - April 2012. In addition to Core, Nehalem and Sandy Bridge models, that document also includes third generation Core i5-3xxx and i7-3xxx desktop and mobile chips:

The PDF doesn't list any i3-3xxx Ivy Bridge microprocessors, that are supposedly coming in May or June. Specifications of most processors in the document match previously leaked roadmaps. The flipbook does contain a few new previously unknown Ultra Low Voltage parts, such as Core i7-3517U and Core i5-3317U. Details of these ULV processors were disclosed by VR-Zone a few hours ago.

Ivy Bridge (microarchitecture)

Ivy Bridge is the codename for Intel's 22 nm die shrink of the Sandy Bridge microarchitecture based on tri-gate ("3D") transistors. Ivy Bridge processors backwards-compatible with the Sandy Bridge platform might require a firmware update (vendor specific)^[1][2], check here for chipset compatibility. Intel will release new 7-series Panther Point chipsets with integrated USB 3.0 to complement Ivy Bridge.^[3]

Intel announced that it had begun production of Ivy Bridge chips in volume in the third quarter of 2011^[4][5][6] with retail availability starting in April 2012,^[7] one source specified April 8 as the availability date.^[8] In February 2012, it was reported that Intel would postpone the launch of the dual-core mobile CPUs (not desktop CPUs or quad-core mobile CPUs) to June 2012 to allow more time to sell surplus inventory of Sandy Bridge CPUs, which accumulated due to slower than expected computer sales.^[9]

[edit]Features

Ivy Bridge feature improvements over Sandy Bridge include:^[10][11]

• Tri-gate transistor technology (less than 50% power consumption at the same performance level as 2-D planar transistors).^[12]
• PCI Express 3.0 support.^[13]
• Max CPU multiplier of 63 (57 for Sandy Bridge).^[14]
• RAM support up to 2800MT/s in 200MHz increments.^{[citation needed]}
• Intel HD Graphics with DirectX 11, OpenGL 3.1, and OpenCL 1.1 support.^[15]
• The built-in GPU is believed to have up to 16 execution units (EUs), compared to Sandy Bridge's maximum of 12.^[16]
• A new random number generator and the RdRand instruction,^[17] codenamed Bull Mountain.^[18]
• Intel Quick Sync Video.^[16]
• DDR3L low voltage for mobile processors.
• Multiple 4K video playback.

Thermal design power (TDP), according to an October 2011 leaked Intel roadmap, will come in 77/65/55/45/35W options for desktop processors,^[19] while Intel says that mobile processors will use variable TDP (for example TDP of 15W, which automatically rises to 35W when the laptop is plugged into a docking bay; with a corresponding rise in performance).^[20]

[edit]Performance

Performance according to sources (compared to Sandy Bridge):

• Up to 20% increase in CPU performance.^[21]
• 30% to 100% increase in integrated GPU performance.^[22] [23]

Citing issues with the 22 nm manufacturing process, Intel postponed the release of its 22 nm "Ivy Bridge" Core processor family by as much as 10 weeks. There still seems to exist some confusion surrounding this launch, which SweClockers sought to clear with its latest article containing important dates related to the launch.

• 8 April, 2012: This was supposed to be the day "everything" (all CPU models slated for April, compatible motherboards) launched. Instead on this day, motherboard vendors will launch their products based on Intel Z77, Z75, H77, and B75 chipsets. System builders (you) will have to use existing "Sandy Bridge" processors, which are very much compatible with those motherboards. You will not be able to buy "Ivy Bridge" processors from anywhere on this day.
• 29 April, 2012: This is when Intel will launch quad-core Core i5, Core i7 "Ivy Bridge". On this day, the media will be able to post reviews of the new processor platform. It's not clear if you'll be able to buy these chips on this day, either. Perhaps you might.
