The name Quick means FAST, Path means a Particular Route. So Intel Core i7, acquired this Technology for point-to-point high-speed links to distributed shared memory.

It is rightly said: A small thinking can change the world. A small change in Architecture has increased our Working speed to Unimaginable thoughts.

Early a kind of Action to performed were sent by the Control signals and then to the Memory Controller to Processor to Memory Controller to Main Memory. This process was quite Time consuming, But Nehalem and Tukwila Architecture introduced Memory Controllers attached directly to the Processor hence decreasing Time for a particular Process and increasing the Speed.

Quick Path Architecture

The above combination of Nehalam and Tukwila Architecture includes memory controllers integrated into the microprocessors, which are connected together with a high-speed, point-to-point Interconnect. The Quick Path Interconnect provides High Bandwidth and Low Latency.

Processor Interface

Earlier Intel began with, Front-Side bus that consist of single shared bi-directional bus. To further increase the bandwidth of the Front-side bus based platforms, the single-shared bus approach evolved into Dual Independent buses. The DIB approach was extended to its logical conclusion with the introduction of dedicated high-speed interconnects (DHSI).

Then came the Fastest Technology of the Universe, the Quick Path Technology.

The Quick Path Interconnect is a High-speed point-to-point interconnect. The processor may have one or more cores. When multiple cores are present, they may share caches or have separate caches. The processor also typically has one or more integrated memory controllers.

There are Two Unidirectional Inter-connects one for sending-out the Signals and other for Receiving the Incoming Signal. Hence the Processors need not wait in times of Sending and Receiving Signals at a particular instant of Time. As earlier it had to first send or receive signals and perform the alternative process according to the Priority.

So from above all we can easily say that Quick Path Technology features an integrated Memory Controller and High-Speed Interconnect, Linking processors and other components to deliver:
Dynamically scalable interconnect bandwidth.
Outstanding memory performance and flexibility.
Tightly integrated interconnect reliability, availability, and serviceability (RAS).
Optimal balance of price, performance, and energy efficiency.

Such New changes can be Key Ingredient in keeping Pace with the Next Generation of Microprocessors. So keep Thinking and Reading……..
