motherboard for i3 processor 4th generation

Around twice the integrated graphics performance compared to Clarkdale's (12 EUs comparison).ġProcessors featuring Intel's HD 3000 graphics are set in bold.

The average performance increase, according to IXBT Labs and Semi Accurate as well as many other benchmarking sites, at clock to clock is 11.3% compared to the Nehalem generation, which includes Bloomfield, Clarkdale, and Lynnfield processors.

Ivy Bridge CPUs all have CPUID 0306A9h to date, and are built in four different configurations differing in the number of cores, 元 cache and GPU execution units: The later Sandy Bridge-E processors with up to eight cores and no graphics are using CPUIDs 0206D6h and 0206D7h. The stepping number cannot be seen from the CPUID but only from the PCI configuration space.

Integrated graphics is now integrated on the same dieĪll Sandy Bridge processors with one, two, or four cores report the same CPUID model 0206A7h and are closely related.

Intel Quick Sync Video, hardware support for video encoding and decoding.Translation lookaside buffer sizes CacheĪll translation lookaside buffers (TLBs) are 4-way associative. Larger Scheduler buffer (54-entry, up from 26-entry).Increased ROB to 168 entries (From 128).A 14- to 19-stage instruction pipeline, depending on the micro-operation cache hit or miss.This tighter integration reduces memory latency even more. In contrast, Sandy Bridge's predecessor, Clarkdale, has two separate dies (one for GMCH, one for processor) within the processor package. Integration of the GMCH (integrated graphics and memory controller) and processor into a single die inside the processor package.Up to 8 physical cores, or 16 logical cores through hyper-threading (From 6 core/12 thread).Advanced Vector Extensions (AVX) 256-bit instruction set with wider vectors, new extensible syntax and rich functionality.256-bit/cycle ring bus interconnect between cores, graphics, cache and System Agent Domain.Improved performance for transcendental mathematics, AES encryption ( AES instruction set), and SHA-1 hashing.

Sandy Bridge has a single BTB that holds twice as many branch targets as the L1 and L2 BTBs in Nehalem. Sandy Bridge retains the four branch predictors found in Nehalem: the branch target buffer (BTB), indirect branch target array, loop detector and renamed return stack buffer (RSB).Decoded micro-operation cache, and enlarged, optimized branch predictor.Two load/store operations per CPU cycle for each memory channel.Improved 3 integer ALU, 2 vector ALU and 2 AGU per core.Shared 元 cache which includes the processor graphics ( LGA 1155).32 KB data + 32 KB instruction L1 cache and 256 KB L2 cache per core.Intel demonstrated a Sandy Bridge processor with A1 stepping at 2 GHz during the Intel Developer Forum in September 2009.
