The Intel VT offers hardware support for virtual systems on one computer (use of several isolated operation systems at the same time e.g. One 128-Bit SSE command is now output per clock cycle. Intel doubled the bandwidth to the level 1 cache though. Like the Core Duo, the Core 2 Duo has shared level 2 cache and each core receives the same amount of cache. Shorter idle times, improved data transfer and faster out-of-order command execution lead to better usage of the pipeline and as a result to higher performance. Prevents security problems through buffer overflows, if the operation system supports it and if it is activated.Įvery core can execute four complete commands simultaneously. Two processor cores run with the same frequency in the same processor building block and share the level 2 cache as well as the front side bus (FSB). Furthermore it supports the multimedia extension MMX, SSE2, SSE3 and SSE4. The Intel Core 2 Duo uses the x86 instruction set, which was introduced in 1978 with the 8086/8088 processor. The Core 2 Duo processors are produced in 65 nm (and later in 45nm), contain 14 stages pipelines and 2-4 MB level 2 cache (depending on the model).
