What is Sandy bridge-e in the CPU

The Sandy BRIDGE-E processor became a new generation of kings without any suspense after the recent release. It is a number of pins close to the previous generation of products twice times the processor, but it does follow the framework of SNB and to expand it, on the size of the specification is absolutely the current top level products, we do not need to guess its performance, Just know how tough it can be.

The Sandy BRIDGE-E Core i7 Extreme processor will be based on the six core 12 thread design, the default frequency is 3.3GHz, the most Gao frequency reaches the 3.9GHZ,L3 cache capacity to reach the desktop record 15MB. The normal version of the Core i7 processor is again divided into six cores 12 threads and four cores eight threads two versions, one of the six nuclear version of the default frequency of 3.2GHz, the core frequency for 3.8GHZ,L3 cache cut to 12MB; The four-core version of the default frequency slightly higher, reached 3.6GHz, the core frequency is with Sandy BRIDGE-E Core i7 Extreme Same, also for 3.9GHZ,L3 cache is further cut to 10MB, three of sandy Bridge-e Core i7 processor TDP power consumption is 130W.

The flagship core i7-3960x of the Sandy BRIDGE-E processor also employs six physical core designs with the previous core i7-990x, and Hyper-Threading technology still provides support, so the flagship core The I7-3960X processor has six physical cores and 12 threading specifications. In addition to the Core i7 3960X adopted a new interface specification, the memory channel also from the previous generation of three channels upgraded to four channels. The level three cache is also extended to 15MB, which also brings a performance boost to Core i7 3960X.

Apparently Sandy Bridge-e brings more new features than LGA1366 's Nehalem processor, and Sandy Bridge-e has more attractive features than the Sandy Bridge processor.

Compared with the LGA1366 Nehalem processor, Sandy Bridge-e uses the same ring-like architecture as Sandy Bridge, which shortens data latency, improves processor computing efficiency, and increases L3 cache utilization.

Compared to the current Sandy Bridge, the two-point change brought about by the Sandy BRIDGE-E processor is the built-in ddr3-1333 four-channel memory controller and two PCI-E X16 channels provided by the CPU. The built-in ddr3-1333 four-channel memory controller delivers up to 42.7gb/s of memory bandwidth, 66% higher than the 25.6gb/s of the LGA1366 ddr3-1066 three-channel memory controller, and, more coincidentally, according to Intel's confidential slide show, The LGA2011 Sandy BRIDGE-E processor will be up to 66% higher than the LGA 1155 Sandy Bridge processor core i7-2600 performance.

Compared with the LGA1366 Nehalem processor, Sandy Bridge-e uses the same ring-like architecture as Sandy Bridge, which shortens data latency, improves processor computing efficiency, and increases L3 cache utilization.

But not the Sandy Bridge-e processor is perfect, compared to the Sandy Bridge processor, the former, although also using a fusion design, but the built-in GPU display chip may be blocked off, and can greatly speed up the speed of the transcoding quick Sync also disappeared from the technical support list.

Hyper-Threading Technology for Sandy BRIDGE-E

Core i7-3960x by virtue of the fact that we mentioned hyper-Threading technology, we were able to see 12 threads working in a real system, which is why Intel's Hyper-Threading technology works. Do not underestimate the hyper-threading out of the 12 threads, which can be rendered when we implement 12 threads common rendering, equivalent to virtual out of 12 core processing tasks.

The core frequency still exists on this generation system

The core frequency technology in the previous generation processor still exists in the sandy bridge-e, this also enables the user to realize the automatic overclocking in the actual use, the actual feeling is the security, the worry, the stability. Here's a simple example to illustrate, Core i7 3960X Extreme Edition increases the frequency of a single core to the most Gaorui at the time of a single task, which optimizes the performance of a single core (two-thread), while others reduce the frequency to avoid unnecessary waste of power; The Core i7 3960X Extreme Edition, when performing high load multitasking, promotes six cores (12 threads) to a lower frequency, which can optimize program performance while controlling power consumption.
