Broadwell (previously Rockwell) is the fifth generation of the Intel Core processor. It is Intel's codename for the 14 nanometer die shrink of its Haswell microarchitecture. It is a "tick" in Intel's tick–tock principle as the next step in semiconductor fabrication. [2] [3] [4] Like some of the previous tick-tock iterations, Broadwell did not completely replace the full range of CPUs from the previous microarchitecture ( Haswell), as there were no low-end desktop CPUs based on Broadwell. [5]
Some of the processors based on the Broadwell microarchitecture are marketed as "5th-generation Core" i3, i5 and i7 processors. This moniker is however not used for marketing of the Broadwell-based Celeron, Pentium or Xeon chips. This microarchitecture also introduced the Core M processor branding.
Broadwell is the last Intel platform on which Windows 7 is supported by either Intel or Microsoft; however, third-party hardware vendors have offered limited Windows 7 support on more recent platforms. [6]
Broadwell's H and C variants are used in conjunction with Intel 9 Series chipsets ( Z97, H97 and HM97), [7] in addition to retaining backward compatibility with some of the Intel 8 Series chipsets.[ citation needed]
Broadwell has been launched in three major variants: [8]
Broadwell introduces some instruction set architecture extensions: [17] [18]
ADOX
and ADCX
for improving performance of
arbitrary-precision
integer operations
[19]
RDSEED
for generating 16-, 32- or 64-bit
random numbers from a
thermal noise entropy stream, according to NIST SP 800-90B and 800-90C
[20]
PREFETCHW
instruction
[20]Broadwell's Intel Quick Sync Video hardware video decoder adds VP8 hardware decoding [22] and hybrid encoding [23] support. [24] HEVC decode is achieved through a combination of the fixed function video decoder and shaders. [25] Also, it has two independent bit stream decoder (BSD) rings to process video commands on GT3 GPUs; this allows one BSD ring to process decoding and the other BSD ring to process encoding at the same time. [26]
Broadwell's integrated GPU supports on Windows Direct3D 11.2, OpenGL 4.4 (OpenGL 4.5 on Linux [27]) and OpenCL 2.0. [28] [29] [30] However, it is marketed as Direct3D-12-ready. [31] Broadwell-E introduced Intel Turbo Boost Max Technology 3.0. [32]

On September 10, 2013, Intel showcased the Broadwell 14 nm processor in a demonstration at IDF. Intel CEO Brian Krzanich claimed that the chip would allow systems to provide a 30 percent improvement in power use over the Haswell chips released in mid-2013. Krzanich also claimed that the chips would ship by the end of 2013; [41] however, the shipment was delayed due to low yields from Intel's 14 nm process. [42]
On October 21, 2013, a leaked Intel roadmap indicated a late 2014 or early 2015 release of the K-series Broadwell on the LGA 1150 platform, in parallel with the previously announced Haswell refresh. This would coincide with the release of Intel's 9-series chipset, which would be required for Broadwell processors due to a change in power specifications for its LGA 1150 socket. [43] [44]
On May 18, 2014, Reuters quoted Intel's CEO promising that Broadwell-based PCs would be on shelves for the holiday season, but probably not for the back-to-school shopping. [45]
Mobile CPUs were expected in Q4 2014 and high-performance quad-core CPUs in 2015. The mobile CPUs would benefit from the reduced energy consumption of the die shrink. [46] [47]
On June 18, 2014, Intel told CNET that while some specialized Broadwell-based products would be out in Q4 2014, "broader availability" (including mobile CPUs) would only happen in 2015. [48]
As of July 2014 [update], Broadwell CPUs were available to Intel's hardware partners in sample quantities. [49] Intel was expected to release 17 Broadwell U series family microprocessors at CES 2015. [50] Also, according to a leak posted on vr-zone, Broadwell-E chips would be available in 2016. [51]
On August 11, 2014, Intel unveiled formally its 14 nm manufacturing process, and indicated that mobile variants of the process would be known as Core M products. Additionally, Core M products were announced to be shipping during the end of 2014, with desktop variants shipping shortly after. [52]
With Broadwell, Intel focused mainly on laptops, miniature desktops, and all-in-one systems. [53] This left traditional desktop users with no new socketed CPU options beyond fourth-generation Haswell, which first arrived in 2013. Even though the company finally introduced two Broadwell desktop chips in the summer of 2015, it launched its high-end sixth-generation Skylake CPUs very shortly thereafter. In September 2015, Kirk Skaugen, senior vice president and general manager of Intel's Client Computing Group, admitted that skipping desktops with Broadwell was a poor decision. Between the end-of-life for Windows XP in 2014 and the lack of new desktop chips, Intel had not given desktop PC users any good reasons to upgrade in 2015. [53]
On September 5, 2014, Intel launched the first three Broadwell-based processors that belong to the low-TDP Core M family, Core M 5Y10, Core M 5Y10a and Core M 5Y70. [54]
On October 9, 2014, the first laptop with Broadwell Intel Core M 5Y70 CPU, Lenovo Yoga 3 Pro, was launched. [55]
On October 31, 2014, four more Broadwell based CPUs were launched belonging to Core M Family, increasing the number of launched Broadwell CPUs to seven. [56]
On January 5, 2015, 17 additional Broadwell laptop CPUs were launched for the Celeron, Pentium and Core i3, i5 and i7 series. [57]
On March 31, 2016, Intel officially launched 14 nm Broadwell-EP Xeon E5 V4 CPUs. [58]
On May 30, 2016, Intel officially launched 14 nm Broadwell-E Core i7 69xx/68xx processor family.
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.
