What is Intel Core i7?

The first generation of Core i7 (English: core i7, core code: Bloomfield) processor) is the 64-bit quad-core CPU, introduced by Intel in 2008, which uses the x86 CPU, 64 instruction set and replaces the Intel Core 2 series processors based on the Intel Nehalem microarchitecture. Nehalem was once the code name for the Pentium 4 10 GHz version. The name Core i7 has no special meaning. Intel says the reason for taking the name i7 just sounds pleasant. "I" means smart (the initials of intelligence), while 7 has no special meaning, let alone the seventh generation product. And Core is to continue the success of the previous generation of Core processors, some people will be nicknamed "beloved wife". The official launch date is November 17, 2008. As early as November 3, officials have announced the prices of related products, and online reviews have been unblocked one after another. The
Core i7 processor family will no longer use words such as Duo or Quad to identify the number of cores. The most advanced Core i7 processor comes with the Intel X58 chipset. The goal of the Core i7 processor is to improve high-performance computing and virtualization performance. Therefore, in terms of computer games, its performance improvement is limited. In addition, macro fusion mode can be started in 64-bit mode, and the previous generation of Core processors only supported macro fusion in 32-bit mode. This technology can combine some X86 instructions into a single instruction to speed up the computing cycle.
Core i7 is expected to release a 32-nanometer process in 2010, and Intel said the i7, codenamed Gulftown, will have six physical cores, also support hyper-threading technology, and downwards support today's X58 chips. The
Intel Core i7 fist- generation parameter
Intel Core i7900 series is a 45nm native quad-core processor with three levels of 8MB cache and three channels of DDR3 memory. The processor is designed with LGA 1366 pins and supports the second generation of hyper-threading technology, that is, the processor can run with eight threads.
Inter Corei7 second-generation parameter
Inter Corei7 2600 series is a 32nm native quad-core processor, which has 8MB three-level cache and supports dual-channel DDR3 memory. The processor is designed with LGA 1155 pins and supports the second generation of hyper-threading technology, that is, the processor can run with eight threads.
