The K series appeared in 2010, signifying that the clock function is unlocked at 3.3GHz, enabling a new generation of Turbo Boost 2.0 technology, with performance up to 3.70GHz. Entity 4 Cores but without Hyper-Threading technology and a total of up to 4 threads, referred to as 4C/4T 32nm process technology, power 95W, total of 6MB L3 Cache. The LGA 1155 is currently in the second rank of the high-end CPUs. [IMG]http://www.twcarpc.com/photo/wwm/2011/EH67/EH6715.jpg[/IMG] Because the Sandy Bridge i3 series will be on the market after the end of February, at this point for testing we'll use the high-end 4Cores i5. Later, if I get my hands on an i3-2100, I will do detailed performance tests to understand the actual performance of the built-in GPU on the i5-2500K.

The H67 and P67 chipsets were very similar in performance under default settings, and the performance was not bad. Compared with the previously reviewed i5-760, the new 2500K CPU had performance improvements of about 2 to 3 percent On one hand, with the same clock speed, the LGA 1155 had about 10% higher performance than the LGA 1156 With the i5-2500K at 3.3GHz added to the mix, the i5-760 running at 2.8GHz was the only factor behind differences in performance. This is provided to all netizens as a reference. DDR3 bandwidth comparison DDR3 1064.4 CL7 7-7-20 1T ADIA64 Memory Read - 14091 MB/s Sandra Memory Bandwidth - 14133 MB/s [IMG]http://www.twcarpc.com/photo/wwm/2011/EH67/EH671333MEM.png[/IMG] From the above bandwidth performance test of DDR3, we can see improvements on the problems of the older generation It is simply the built-in GPU of the CPU that lowers the bandwidth of the DDR3. This is a special characteristic of the LGA 1156 i3/i5 32nm CPU. The Sandy Bridge i5-2500K has the same built-in GPU but the DDR3 bandwidth allows excellent performance. Only working with DDR3 1064, it already operates at a bandwidth about 36 to 59% higher than the previous generation i3-540 DDR3 1333. We hope that in the future we will have the opportunity to share our experience with the i3-2100 operating with such a high bandwidth. The lack of BIOS options for DDR3 1333 is something of a drawback. [/QUOTE]
