Intel Haswell details leaked

Intel chip leaks are gathering pace. While the world is waiting for Chipzilla’s Ivy Bridge, we are starting to see information on the next-generation processor architecture after that.

Dubbed Haswell, it will be based on a 22nm fan process which Intel hopes will be sorted out by Sandy Bridge’s successor, Ivy Bridge.

Tweaktown calls this Chipzilla’s “tick-tock” product development model. A “tock” is the new x86 architecture, and a “tick” miniaturises it to a newer silicon fabrication process.  So Haswell is a bit of a tock.

The leaked slides show that Haswell will be with us in the middle of 2013, with Ivy Bridge taking the lead from Q2 2012 until then.

Haswell will have a new socket, LGA1150, which means it will not be compatible with LGA1155 boards. It looks like this is needed because Chipzilla has made serious changes in the pin map of the package.

Haswell uses a higher bandwidth chipset bus, with rearranged PCIe pins. There is no separate power domain for the integrated graphics controller.

Haswell will include the next-generation RapidStart quick boot capabilities that reduce cold-boot times to two seconds, in line with the Ultrabook model. The processor’s IPC will be increased and the mobile version is designed to increase battery life of mainstream notebooks. Haswell has improved HD transcoding capabilities too.

It promises near-field communication, and Thunderbolt to non-Apple users.

The platform is something called Shark Bay, and will be available in 2-chip quad-core and 1-chip dual-core flavours.

The quad-core chips and some dual-core chips will use the usual socketed motherboard with a single-chip chipset (PCG). The slides hint that this will be much smaller than today’s PCH chips.

Meanwhile, some dual-core chips will completely integrate the PCH into the processor’s package and remove the need for an external chipset.
