The physical cores largely determine the speed of a processor. S: Special Edition processors, usually featuring very high-performance hardware.These high-performance CPUs can be overclocked, but they do not come with onboard graphics. This means you can overclock the processor above its rating. G1-G7: The level of integrated graphics performance you can expect.Typically found on laptops, this means there is a dedicated GPU with the processor. Optimized for mobile hardware, with a quad-core processor. HK: High-Performance Mobile, but also has an unlocked CPU which allows for overclocking.These CPUs are high-performance models optimized for mobile hardware. T: Power Optimized for desktop processors.Processors designed for devices with extremely low power requirements, such as Internet of Things devices or other embedded hardware. These draw less power and are better for battery life. The U rating is only for mobile processors. KĪs you can see, the model number will typically be followed by one or a combination of the following letters: U, Y, T, Q, H, G, and K. What Intel's Model Letter Suffixes Mean: U vs.
