Enabling Intel Turbo Boost Technology and Graphics Dynamic Frequency will maximize 

the performance of the processor core and the GPU within its specified power levels. 

Compared with previous generation products, Intel Turbo Boost Technology and 

Graphics Dynamic Frequency 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. For more 

details, refer to 

A new set of Single Instruction Multiple Data (SIMD) instructions is introduced in this 

generation of processor. These instructions enable fast and secure encryption and 

decryption using AES. The new architecture introduces six Intel® SSE instructions. 

Four instructions, namely AESENC, AESENCLAST, AESDEC, and AESDELAST facilitate 

high performance AES encryption and decryption. The other two, namely AESIMC and 

AESKEYGENASSIST, support the AES key expansion procedure. Together, these 

instructions provide a full hardware for support AES, offering security, high 

performance, and a great deal of flexibility.

The carry-less multiplication instruction, PCLMULQDQ, is a new Single Instruction 

Multiple Data (SIMD) instruction that computes the 128-bit carry-less multiplication of 

two, 64-bit operands without generating and propagating carries. Carry-less 

multiplication is an essential processing component of several cryptographic systems 

and standards. Hence, accelerating carry-less multiplication can significantly contribute 

to achieving high-speed, secure computing and communication.
