i7 processors feature a larger cache, hyper-threading, and a higher clock speed.Įven so, computer processors are rarely the bottleneck in performance these days. Other dual core processors aside from Core 2 Duo are the Core Duo from Intel and the X2 series from AMDĤ.Intel Core i7 is a high-end processor and is more appropriate than the i5 processors for certain intensive tasks, such as data crunching, graphics and video editing, and PC gaming. Core 2 Duo is the second line of dual core processors from Intelģ. Dual core is the generic name given to processors that have 2 cores on the same chipĢ. We can therefore say that Core 2 Duo is simply a subset of all the dual core processors that are out in the market today.ġ. If we translate this to the single core processors, we can say that Core Duo is Pentium 1 while Core 2 Duo is Pentium 2, while AMD has their own processors with different names but all these are still single core processors. As they refined their product more, they decided to differentiate their second set of processors from the Core Duo and decided to call it Core 2 Duo.īasically, the difference between dual core processors and the Core 2 Duo processors is just in the semantics as Core 2 Duo is simply a name given to a more recent family of dual core processors. Intel’s dual core processors were simply 2 Pentium 3 processors that were fabricated in a single chip. Initially, Intel called their dual core processors as Core Duo, a very obvious reference to two cores, while AMD called theirs the X2. All processors that have 2 cores in them are collectively called as dual core processors regardless of which manufacturer it came from, while those that have 4 processors in a single chip are called quad core.
Two or more cores can greatly aid in multi-tasking where each core can work independently of each other. Because the number of transistors in a single chip continues to follow its upward trend, processor manufacturers like Intel and AMD have decided to go a different route in increasing the performance of their products, adding more cores into a single chip that leads to a performance boost if the OS supports it. The processor wars have hit a major speed bump as clock speeds become harder and harder to push upwards. Dual core processors are those that contain 2 cores in a single silicon chip while Core 2 Duo is the name given by Intel to its second batch of dual core processors.
