4, no one big bright spot Penryn processor technology and analytical-CPU, Penryn
In this exhibition, the processor giant Intel officially launched the field of 16 models Penryn core processors, users are very worthy of attention. In particular, a new generation of Intel processors, including the four technical highlights, it is very exciting.
45nm Penryn core processor technology features
First, they are using advanced 45nm process. Current IC nanometer process technology is usually used as units of measure, its effect transistor integrated circuit is connected between the line width. Connect the shorter width per unit area of the chip on the number of transistors that can accommodate the more, the performance and functionality will increase as well. 45-nanometer Penryn family of processors in the dual-core version of built-in 410 million transistors, while the four-core version of the even more is the set of built-in record high 820 million transistors. Compared to 65nm products, which can be integrated on a smaller area more transistors, can easily have a higher performance, better overclocking ability and better than the energy consumption.
Second, in the secondary cache area 45nmPenryn core processors overall improvement, with the release of the 7 least two desktop processor cache has reached 6MB, 12MB maximum is reached much! 2 CPU cache size is an important indicator of the structure and size of the impact on the CPU speed is very large, the Penryn processors, this parameter increased to 12MB, for performance improvements is obvious. Compared with previous generation products corresponding to the 45 nm Penryn family of processors, the improvement in graphics performance area is about 15%, video encoding average increase by 20%, three-dimensional content generation capacity increased by more than 25%, game performance gain of more than 40% . As the two of them brought about by the power increase, the cache is not dead.
Third, SSE4 multimedia instruction set processor core Penryn processors, more so even more powerful, the new SSE4 multimedia instruction set will increase the two different 32-bit vector integer multiplication unit, and the introduction of eight unsigned max / minimum operations support, and 16-bit/32-bit signed and unsigned operations support in order to effectively improve the efficiency of the compiler and improve the implementation of vector integer and single precision code of computing power. At the same time, SSE4 multimedia instructions to further improve the insertion, extraction, search, discrete, step load, and storage operation mode, making vector operations become more specialized.
Fourth, get a lower operating power consumption. Through 45-nm process technology, and High-k + MetalGate and other new materials, Intel Yorkfield quad core processors to reduce the area of the core 37%, while the number of transistors has increased by 40%. This power is more easy to control, can enable users to better energy consumption ratio, made by our previous test: the "minimum four-core CPU only 6W45nm measured power consumption and overclocking", I believe we can have more intuitive impression.
16 parameter models and prices Penryn core processors Technical highlights of the four above are
could revolutionize the improving processor can make the performance of computer users have a new experience. And Intel announced the official price comparison, we can surprise than the discovery of the current mainstream processors, 45nm new products while the price in performance was very approachable, which E8200 and Q9300 are likely to be the king of a new generation of popular, very exciting. I can say that in 2008 the biggest change occurred a year of Intel, with its strong performance and excellent price, will allow more consumers to choose the Intel products.
