The first Intel processors with Nehalem architecture will appear at the end of this year. Westmere Processors , will be released on 32 nm technology in the beginning of 2010, it will preserve Nehalem architecture . And only at the end of 2010 can appear Sandy Bridge processors , which will present a new architecture.
Associate published a new article about differences between Nehalem and Sandy Bridge processors and those existing now. Intel representatives statements and information from certain sources, close to motherboard producers are used.
Let us begin from the fact that Nehalem processors server class promise to demonstrate considerable increase in performance relative to 45 nm Clovertown processors , which work at 3.0 GHz frequency . For example, in SPECint_.rate2006 test the performance of integral operations will grow by 1,6 time, and in SPECfp_.rate2006 test the performance of floating point will grow 2,4 time. Interaction between processors will increase due to the use of new system bus QPI, and from the memory controller witch will be transferred to the processor.
By the development of Sandy Bridge generation processors is occupied Israel's engineers . This parallel development diagram allow the release of new processor according to the announcements graph (new architecture is represented every two years ).
Nehalem will unite graphic and processor core in one packing, but physically these components will be placed on separate crystals. And only 32 nm version will obtain the graphic core on monolithic crystal.
Israeli's developers report that the graphic core must be placed on one crystal with the processor. Multi-chip layout does not give the visible advantages.
Here there are some obstacles. The update cycle of graphic core does not usually exceed 6 months, but processor architecture is prepared for much longer. In order to avoid such problem , Israeli's engineers can use processor architecture processors Cell. This will allow the integration of contemporary graphic core or the increase of core quantity without essential design change . Related Products :
