These numbers make a smaller difference than the number in the "iX" part, but they're still important. Intel's chips have letters like "K" and "U" after the numbers that give you an idea of what kind of purpose and performance the computer is designed for.

Some computers have Intel chips without any letters. Those are the standard, base chip models. The " K " chips are usually the fastest, with higher clock speeds than the standard chips without a letter in Intel's mainstream chips. It also means the chip is "unlocked," where its clock speeds can be tweaked — or "overclocked — by a user to squeeze out a little extra performance than what you get out of the box.

Usually, it's mostly enthusiasts who tend to overclock their chips, and they're mostly designed for desktops or high-performance laptops. The " G " means the chip has a built-in graphics processor. Most of Intel's chips come with basic built-in graphics processors so you can display something on your monitor without an entirely separate graphics card. But Intel's "G" processors come with a more powerful graphics processor for more power-hungry apps and games. The " T" means the chips is designed to use less power while also having less performance than the standard chips without any letters.

The " U " means the chip is designed for laptops and mobile devices, as "U" chips are Intel's "ultra-low power" models. They're "low power" because they use even less power than the "T" models and have slower clock speeds than their full-size, non "U" equivalents. By having slower clock speeds, they don't get as hot and have a lower risk of heat-related damage. That's good for thin laptops that have limited cooling compared to larger desktops and laptops. You can find more information about Intel's chip letters on Intel's site , where it shows what other letters mean on previous generation chips.

Cores make a big difference. The more cores you have, the faster you can make your apps do whatever you want them to do.

With Intel's eighth generation of chips, core count doesn't matter as much, as even the majority of the lower-end Core i3 chips have four cores. For instance, Little's law allows SoC states and NoC buffers to be modeled as arrival processes and analyzed through Poisson random variables and Poisson processes.

SoCs are often modeled with Markov chains , both discrete time and continuous time variants. Markov chain modeling allows asymptotic analysis of the system-on-chip's steady state distribution of power, heat, latency and other factors to allow design decisions to be optimized for the common case. The netlists described above are used as the basis for the physical design place and route flow to convert the designers' intent into the design of the SoC.

Throughout this conversion process, the design is analyzed with static timing modeling, simulation and other tools to ensure that it meets the specified operational parameters such as frequency, power consumption and dissipation, functional integrity as described in the register transfer level code and electrical integrity. When all known bugs have been rectified and these have been re-verified and all physical design checks are done, the physical design files describing each layer of the chip are sent to the foundry's mask shop where a full set of glass lithographic masks will be etched.

These are sent to a wafer fabrication plant to create the SoC dice before packaging and testing. FPGA designs are more suitable for lower volume designs, but after enough units of production ASICs reduce the total cost of ownership. SoC designs consume less power and have a lower cost and higher reliability than the multi-chip systems that they replace.


With fewer packages in the system, assembly costs are reduced as well. However, like most very-large-scale integration VLSI designs, the total cost [ clarification needed ] is higher for one large chip than for the same functionality distributed over several smaller chips, because of lower yields [ clarification needed ] and higher non-recurring engineering costs. When it is not feasible to construct an SoC for a particular application, an alternative is a system in package SiP comprising a number of chips in a single package.

When produced in large volumes, SoC is more cost-effective than SiP because its packaging is simpler. SoC research and development often compares many options. From Wikipedia, the free encyclopedia.
