x48

x48 is a term that can refer to several different things, primarily in the context of technology and manufacturing. One common usage is in relation to Intel processors. The "x48" designation often appears in the model numbers of certain Intel Core processors, such as the Core i7-980X Extreme Edition, which was part of the Nehalem microarchitecture. In this context, it typically signifies a specific SKU or a feature set within a particular processor family.

Another significant area where x48 is found is in the semiconductor manufacturing industry, specifically referring to wafer sizes. An x48 wafer, or more commonly a 48-inch wafer, represents a very large diameter substrate used for producing integrated circuits. While 300mm (approximately 12 inches) is the current industry standard for high-volume manufacturing, research and development into larger wafer sizes like 450mm (18 inches) and beyond, which could be conceptualized as related to even larger "x" designations, has been explored. However, a widely adopted "x48" wafer standard is not currently in common use. The term might also appear in specific product codes or internal designations within companies for various components or projects.
