Intel i7-4600U CL8064701477000 Data Sheet

Intel recommends enabling Intel HT Technology with Microsoft Windows* 8 and

Microsoft Windows* 7 and disabling Intel HT Technology using the BIOS for all

previous versions of Windows* operating systems. For more information on Intel HT

The Intel Turbo Boost Technology 2.0 allows the processor core to opportunistically

and automatically run faster than its rated operating frequency/render clock, if it is

operating below power, temperature, and current limits. The Intel Turbo Boost

Technology 2.0 feature is designed to increase performance of both multi-threaded

and single-threaded workloads.

Compared with previous generation products, Intel Turbo Boost Technology 2.0 will

increase the ratio of application power to TDP. Thus, thermal solutions and platform

cooling that are designed to less than thermal design guidance might experience

thermal and performance issues since more applications will tend to run at the

maximum power limit for significant periods of time.

Intel Turbo Boost Technology 2.0 may not be available on all SKUs.

To determine the highest performance frequency amongst active cores, the processor

takes the following into consideration:

•

The number of cores operating in the C0 state.

•

The estimated core current consumption.

•

The estimated package prior and present power consumption.

•

The package temperature.

Any of these factors can affect the maximum frequency for a given workload. If the

power, current, or thermal limit is reached, the processor will automatically reduce the

frequency to stay within its TDP limit. Turbo processor frequencies are only active if

the operating system is requesting the P0 state. For more information on P-states and

 on page 42.

Intel Advanced Vector Extensions 2.0 (Intel AVX2) is the latest expansion of the Intel

instruction set. Intel AVX2 extends the Intel Advanced Vector Extensions (Intel AVX)

with 256-bit integer instructions, floating-point fused multiply add (FMA) instructions,

and gather operations. The 256-bit integer vectors benefit math, codec, image, and

digital signal processing software. FMA improves performance in face detection,

professional imaging, and high performance computing. Gather operations increase

vectorization opportunities for many applications. In addition to the vector extensions,

this generation of Intel processors adds new bit manipulation instructions useful in

compression, encryption, and general purpose software.
