Intel core i7-2920XM i7-2820QM i7-2720QM Sandy Bridge mobile processors
Finally we have started seeing some part numbers for the Intel Sandy Bridge processors the mobile versions. We also have some information about the frequencies of the information and the amount of the Cache in the processors. The Mobile Sandy Bridge processors will have the brand names of core i7 and core i5. For the core i7 series the part number of these processors will be core i7-2920XM, i7-2820QM, i7-2720QM. We also have part numbers for the core i5 processors as Core i5-2540M and core i5-2520M. Based upon the success of the core i5 and the core i7 Intel has decided to go with the brand names of core i7 and core i5 with the Sandy Bridge processors.
We may like to throw some light on the XM and the QM suffix. The XM suffix as in he core i7-2920XM if for the Extreme Edition. The QM suffix reported in i7-2820QM and i7-2720QM actually means the quad core. You may like to note that all these three core i7 parts have 4 cores. The M in the core i7 part numbers indicate the Mobile version.
There will not be any ultra low voltage ULV parts for the mobile processors. It is possible that intel launches them sometimes later.
The Sandy Bridge processors are scheduled to be shipped out to the Original Equipment manufacturers sometimes in the last quarter of 2010. We should start seeing the Sandy Bridge based notebooks and desktops sometimes in the 1st quarter of 2011.
There are 4 cores in all the core i7 processors viz., I7-2920XM, core i7-2820QM and i7-2720QM . They all support Hyperthreading which means that we can see 8 threads simultaneously. It is uncertain how big the hyperthreading will make a difference in the actual performance.
Now the information about the frequencies of these parts. The top of the line inte core i7-2920XM, extreme edition will have a nominal frequency of 2500 MHz. It does support the turbo boost , and its turbo frequency will be 3500 MHz. The level 3 Cache in the Intel core i7-2920XM will be 8 MB.
The next part core i7-2820QM will have a nominal frequency of 2300 MHz and with the turbo boost, it will have turbo frequency of 3.4 GHz. The amount of the Level 3 cache in Intel core i7-2920XM will be 8 MB. In the last one, core i7-2720QM – this part has a nominal core frequency of 2.2 GHz and a turbo frequency of 3.3 GHz. The core i7-2720QM will have a smaller 6 MB L3 Cache.
While the core I7-2920XM, extreme edition has a TDP power rating of 55 Watts, the core i7-2820QM, i7-2720QM have a TDP power rating of 45 Watts.
