Intel Haswell: LGA-1150 i nova 22nm arhitektura za 2013.

We're still an estimated five to six months away from Intel's launch Ivy Bridge, a platform which is expected to offer slight improvements over Sandy Bridge in terms of performance, although it should improve power efficiency and graphics performance quite significantly. However, Intel's 2013 platform code named Shark Bay has now turned up. Intel follows a "tick-tock" product development model. Every year, Intel's product lineup sees either of the two. A "tock" brings in a new x86 architecture, a "tick" miniaturizes it to a newer silicon fabrication process. For example, Sandy Bridge is Intel's latest architecture, and is based on the 32 nm fab process. Ivy Bridge is a miniaturization of Sandy Bridge to 22 nm. Likewise, Haswell will be a brand new architecture, it will use the 22 nm fab process cemented by Ivy Bridge. If all goes well with Intel's 22 nm process, Haswell is scheduled for Q2 2013. 2012 (Q2 onwards) will be led by Ivy Bridge.

But then here's a "shocker": Haswell's desktop version will use a brand new socket, LGA-1150, and will be incompatible with LGA-1155. This is because of drastic changes in the pin map of the package. Sandy Bridge and Ivy Bridge share the LGA-1155 socket, and will hence, have kept the socket alive for over 2 years. A major change with the component arrangement in the platform that is affecting Haswell's pin map is that Haswell will have a higher bandwidth chipset bus, rearranged PCIe pins (with FDI pins), rearranged power pins, and miscellaneous pins. It does away with a separate power domain for the integrated graphics controller. We're of course getting a new chipset, codenamed Lynx Point, although we don't have much in terms of details with regards to new features compared to the 7-series chipsets. One interesting new addition is three levels of Intel graphics, currently known as GT1, GT2 and GT3.

Taking a closer look at the platforms, starting with the desktop we're looking at two or four cores, support for DDR3 and DDR3L (low power) memory at speeds of up to 1600MHz officially in a typical dual-channel configuration with a maximum of two DIMMs per channel. Oddly enough the TDP looks set to go back to 35, 45, 65 and 95W, the same as for Sandy Bridge and an increase from what we're expecting to see from Ivy Bridge. Again, as we reported a few days ago, Haswell will feature a fully integrated Voltage regulator, although unlike Sandy Bridge and Ivy Bridge, Haswell will feature improved overclocking, but we're not sure how far Intel will go here to bring back additional Bclk multipliers.
