Intel® Advanced Digital Media Boost
Intel® Advanced Digital Media Boost is a feature that significantly improves performance when executing Intel® Streaming SIMD Extension (SSE/SSE2/SSE3) instructions.
They accelerate a broad range of applications, including video, speech and image, photo processing, encryption, financial, engineering and scientific applications. Intel Advanced Digital Media Boost feature enables these 128-bit instructions to be completely executed at a throughput rate of one per clock cycle, effectively doubling, on a per clock basis, the speed of execution for these instructions as compared to previous generations.

Intel® Smart Memory Access
Intel Smart Memory Access improves system performance by optimizing the use of the available data bandwidth from the memory subsystem and hiding the latency of memory accesses.
Intel Smart Memory Access includes an important new capability called "memory disambiguation," which increases the efficiency of out-of-order processing by providing the execution cores with the built-in intelligence to speculatively load data for instructions that are about to execute before all previous store instructions are executed.

Intel® Advanced Smart Cache
The Intel Advanced Smart Cache is a multi-core optimized cache that significantly reduces latency to frequently used data, thus improving performance and efficiency by increasing the probability that each execution core of a multi-core processor can access data from a high-performance, more efficient cache subsystem.

Intel® Wide Dynamic Execution
First implemented in the P6 microarchitecture, Intel Wide Dynamic Execution is a combination of techniques (data flow analysis, speculative execution, out of order execution, and super scalar) that enables the processor to execute more instructions on parallel, so tasks are completed more quickly.
Intel significantly enhances this capability with Intel Wide Dynamic Execution. It enables delivery of more instructions per clock cycle to improve execution time and energy efficiency. Every execution core is 33 percent wider than previous generations, allowing each core to fetch, dispatch, execute and retire up to four full instructions simultaneously. Further efficiencies include more accurate branch prediction, deeper instruction buffers for greater execution flexibility, and additional features to reduce execution time.¹
Combined, Intel Wide Dynamic Execution enables increased instruction execution efficiency, thus increasing performance and energy efficiency.

Intel Energy Efficient Performance
While the world has less energy to spare, the need for greater energy-efficient performance becomes increasingly important. But this does not decrease the demand for more powerful compute capabilities. To address this, Intel is delivering new hardware and software innovations that translate into extraordinary computer experiences.
Architecture innovation
Intel weighs every feature added to our next-generation microarchitecture against a strict power/performance ratio-a feature being added must not add more than a one percent power gain for a less than three percent power cost.¹
By measuring the benefit of the performance gain against the cost of power use, Intel is able to design new microarchitecture to deliver greater power efficiency at any power envelope.¹
Building computing headroom and performance that enables a smaller footprint and decreased power demands, Intel® microarchitecture enables new power-conscious design features, including:
