The graphics render frequency is selected dynamically based on graphics workload 
demand as permitted by the processor turbo control. The processor can optimize both 
processor and Processor Graphics performance through power sharing. The processor 
cores and the processor graphics core share a package power limit. If the graphics core 
is not consuming enough power to reach the package power limit, the cores can 
increase frequency to take advantage of the unused thermal power headroom. The 
opposite can happen when the processor cores are not consuming enough power to 
reach the package power limit. For the Processor Graphics, this could mean an increase 
in the render core frequency (above its rated frequency) and increased graphics 
performance. Both the processor core(s) and the graphics render core can increase 
frequency higher than possible without power sharing.

Processor utilization of turbo graphic frequencies requires that the Intel Graphics driver 

to be properly installed. Turbo graphic frequencies are not dependent on the operating 

system processor P-state requests and may turbo while the processor is in any 

processor P-states.

Intel Advanced Vector Extensions (Intel AVX) is the latest expansion of the Intel 
instruction set. It extends the Intel Streaming SIMD Extensions (Intel SSE) from 128-
bit vectors into 256-bit vectors. Intel AVX addresses the continued need for vector 
floating-point performance in mainstream scientific and engineering numerical 
applications, visual processing, recognition, data-mining/synthesis, gaming, physics, 
cryptography and other areas of applications. The enhancement in Intel AVX allows for 
improved performance due to wider vectors, new extensible syntax, and rich 
functionality including the ability to better manage, rearrange, and sort data. For more

The processor supports Advanced Encryption Standard New Instructions (Intel AES-NI) 
that are a set of Single Instruction Multiple Data (SIMD) instructions that enable fast 
and secure data encryption and decryption based on the Advanced Encryption Standard 
(AES). Intel AES-NI are valuable for a wide range of cryptographic applications; such 
as, applications that perform bulk encryption/decryption, authentication, random 
number generation, and authenticated encryption. AES is broadly accepted as the 
standard for both government and industry applications, and is widely deployed in 
various protocols.

Intel AES-NI consists of six Intel SSE instructions. Four instructions, AESENC, 
AESENCLAST, AESDEC, and AESDELAST facilitate high performance AES encryption and 
decryption. The other two, AESIMC and AESKEYGENASSIST, support the AES key 
expansion procedure. Together, these instructions provide a full hardware for 
supporting AES, offering security, high performance, and a great deal of flexibility.
