"Intel's new CPU" Ivy Bridge "gets high fever" double grease burger syndrome "state

Intel's latest CPU, development code name "Ivy Bridge" "3rd Generation Intel Core"Series launched on April 29, and fans who are looking forward to sales at midnight in Akihabara showed excitement such as forming a queue.

However, in this Ivy Bridge, the heat conduction efficiency is lowered by changing the material used for cost reduction, the problem that the CPU becomes high heat has been discovered, and from that form the tragedy called "double grease burger" It is becoming.

Development code name "Sandy Bridge" "2nd generation Intel Core" seriesThe thing that appeared in January 2011. Its code name "Ivy Bridge" has been developed as a model change. It is officially announced as "3rd generation Intel Core" series group on April 24, 2012, and launched nationwide from 29th April.

Ivy Bridge compared with Sandy Bridge,Process ruleHas been miniaturized from 32 nm (nanometer) to 22 nm, thereby reducing power consumption and decreasing the calorific value. Integrated GPU has also been greatly enhanced, performance has doubled as much as Sandy Bridge, and it was talked about self-made PC users.

However, from the reviewer who got samples in advance, there is an indication that fever is more than expected, and indeedHeat spreaderAfter peeling off the shell, we confirmed the contents and found that TIM paste (thermal grease) was used for the heat conductive material between the core and the heat spreader.

I peeled off the heat spreader for a while, the TIM paste stuck firmly. By the way, the fact that TIM paste is used as a heat conductive material itself is not strange, but in this case the TIM paste used has a thermal conductivity of 5W / mKIt means that it was an item of degree.


In the case of Sandy Bridge, Fluxless solderer (solder) was used for bonding the heat spreader, and its thermal conductivity was about 80 W / mK. Although Ivy Bridge has decreased heat generation, the thermal conductivity has decreased further. Also, not only due to the heat conduction material, it is said that there have been changes due to the heat related technology so far, and this area is considered to be the cause of high fever.

If you are a bit familiar with PCs, I will do my own expansion of HDD and memory, but the "shell split" in this case is more difficult. In the first place a layer like Ivy Bridge to purchase new CPUs immediately after releaseOverclockingEven among the many people who are doing it, it is lightly "Leave the shell and manage it" level not to say.

Although this is a movie that "splits", it is pointed out that it is not a very smart way to use a knife.

If Ivy Bridge is used, if performance is tripled compared with Sandy Bridge, it is a place to worry, but it does not mean that there is no difference there ... ....
