Haswell is the codename for a processor microarchitecture developed by Intel as the successor to the Ivy Bridge architecture.[1] It uses the 22 nm process.[2] Intel officially announced CPUs with this microarchitecture on June 4, 2013 at Computex Taipei 2013.[3] With Haswell, Intel introduced a low-power processor designed for convertible or "hybrid" Ultrabooks, having the Y suffix. Intel demonstrated a working Haswell chip at the 2011 Intel Developer Forum.[4]

Haswell CPUs are used in conjunction with the Intel 8 Series chipsets.

Design[edit]

The Haswell architecture is specifically designed[5] to optimize the power savings and performance benefits from the move to FinFET (non-planar, "3D") transistors on the improved 22 nm process node.[6]

Haswell has been launched in three major forms:[7]

  1. Desktop version (LGA 1150 socket): Haswell-DT
  2. Mobile/Laptop version (PGA socket): Haswell-MB
  3. BGA version:
    • 47 W and 57 W TDP classes: Haswell-H (For "All-in-one" systems, Mini-ITX form factor motherboards, and other small footprint formats.)
    • 13.5 W and 15 W TDP classes (MCP): Haswell-ULT (For Intel's UltraBook platform.)
    • 10 W TDP class (SoC): Haswell-ULX (For tablets and certain UltraBook-class implementations.)

Haswell refresh[edit]

According to Intel roadmaps, Broadwell would not be coming to desktops in mid-2014 if at all. Instead, Intel scheduled a refresh of Haswell, simply titled "Haswell refresh", for the middle of the year, which offers modest clock bumps over existing parts. These new parts would also be compatible with the new Intel's 9 Series chipsets (Z97 and H97). Later it was also revealed that overclockable parts, codenamed "Devil's Canyon", would employ a new and improved thermal interface material (TIM), which would improve their overclocking potential as something that had been problematic since the introduction of Ivy Bridge. Intel also announced plans to mark the occasion by releasing the new Pentium Anniversary Edition, which would include an unlocked version.[59]

  1. When a cooler or quieter mode of operation is desired, this mode specifies a lower TDP and lower guaranteed frequency versus the nominal mode.[70]:71–72
  2. This is the processor's rated frequency and TDP.[70]:71–72

"Configurable TDP (cTDP) and Low-Power Mode (LPM) form a design vector where the processor behavior and package TDP are dynamically adjusted to a desired system performance and power envelope. [...] With cTDP, the processor is now capable of altering the maximum sustained power with an alternate guaranteed frequency. Configurable TDP allows operation in situations where extra cooling is available or situations where a cooler and quieter mode of operation is desired."

"If the CPU needs to work hard for an extended period of time and the laptop gets warmer, it will slowly ramp down its speed until it's operating at its stated TDP. [...] There are two OEM-configurable "power level" states that define how quick the CPU can be in these situations: PL2 tells the processor how much power it's allowed to use when it needs a short burst of speed, and PL1 defines how quickly the processor can run under sustained load. [...] This is at the heart of what Intel is doing with the Y-series processors: their maximum TDP has been lowered four watts, from 17 to 13. Intel is also validating them for use at two lower PL1 values: 10 watts and 7 watts. This is where the marketing we discussed earlier comes in—rather than keeping these values under the covers as it has so far been content to do, Intel has taken that lowest value, put it on its product pages, and called it SDP."
