Powerful processor of the second generation Intel Core i5, whose brand new Sandy Bridge architecture brings many improvements. The processor has four cores and the same number of threads or fibers application. Native operating frequency of each core is 3.3 GHz with a short-term overclock to 3.7 GHz. This allows increasing the frequency of Intel Turbo Boost Technology, which in the new architecture significantly improved its. Unlike the previous generation is permitted to raise short-term rate exceed the maximum CPU TDP, which means in practice so far unprecedented acceleration of computational tasks such as short-run applications, load web pages or just open a new window system. Everything happens automatically and safely under the supervision of the power management unit PCU. The performance of the processor has a considerable influence L3 cache memory, which in this model has a size of 6 megabytes The use of the processor will require a motherboard with a new socket LGA 1155, where the maximum heat output processor (TDP) will be 95 W. The model falls into a higher performance-segment. Its deployment will be ideal especially in reports aimed at performance computing and multimedia applications including gaming.
Most progress in the new 32nm Sandy Bridge architecture will certainly underwent an integrated graphics subsystem Intel HD Graphics. Revolutionary change is to move directly to the GPU chip processor cores. In previous series processors Clarkdale / Arrandale graphics core was separated and combined with processor cores QPI bus. The new proposal “on-die” connection eliminates this, which brings much more effective communication. Graphics engine to provide twice the performance, which is comparable with standalone graphics cards lower class (eg ATI Radeon HD 5450). Now you will be able to smoothly play on a lower setting and modern games, which for the previous generation integrated graphics were taboo. With a revamped GPU also comes integrated logic to encode or convert video to another format, full access to the L3 cache memory, and the Turbo frequency that was previously only a particular inflection-core processor. Thanks to our own power, it is possible independently of the CPU to temporarily increase contacts and GPU, up to 1100 MHz, 850 MHz of the core.
Progress in the new architecture also underwent instruction set. Its designation is AVX (Advanced Vector Extension) and a superstructure of the latest version of SSE x86 architecture. Path vector registers extends from 128 to 256 bits, which you will appreciate especially in difficult calculations with floating point and other applications that frequently use cryptographic algorithms. Innovative AVX instruction set is supported only on Microsoft operating system Windows 7 SP1 and current Linux distributions.
It is now part of the Sandy Bridge architecture and the System Agent, which is actually equivalent to the North bridge located in the CPU. It provides direct access to 16 PCI Express 2.0, which can be divided into two x8. It contains revised 2 channel DDR3 memory controller (up to 1333 MHz) memory with a significantly reduced latency and twice as many operations per 1 cycle, DMI Interface, Display Engine and Power Management Unit PCU (Power Control Unit).
The last notable new Ring Bus is a bus that was previously only Vidana-performance server processors. Ring Bus is a common bus for each of the cores, L3 Cache, graphics core and System Agent. Its use promises greater bandwidth goes hand in hand with larger data flows and lower access times (up to a third).
