As early as four months ago, there was news that Intel was considering standardizing the Sandy Bridge-E processor with a water-cooled heatsink to cope with high power consumption and overclocking needs. AMD's bulldozers series may also be like this, but in the end, Intel chose Some people are surprised that the three new Core i7-3960X/3930K/3820 products will leave the country alone and will not come with any original radiators.
Intel used a tower-mounted heatsink with a side-mounted fan on the Core i7-900 series high-end six-core, but even this is not enough to cope with Sandy Bridge-E, because the latter's thermal design power (TDP) nominal is still 130W. , But it is said that the actual power consumption is already close to 180W, and it is still in the case of not overclocking. In fact, according to the guidelines provided by Intel to power suppliers, Sandy Bridge-E needs to ensure that the peak supply current of the 12V2 circuit is not less than 23A while the power conversion efficiency is not less than 80%.
Naturally, water cooling will be the best partner for Sandy Bridge-E, especially for high-end models. Ultimate overclockers will naturally choose liquid nitrogen, but the current Sandy Bridge-E engineering sample once again shows a Cold Bug, which means that the processor can easily stop working at very low temperatures. It is hoped that the new stepping version of C1 that was eventually released will eliminate this problem.
In fact, there is no surprise in terms of prices. As we previously expected, Intel will still stay at those long-standing prices. The top-end Extreme Core i7-3960X has a wholesale price of $999, which is the same as many extreme versions since the Pentium 4 era. Of course, this time without a radiator, it needs to be purchased separately and the actual price is slightly higher.
The Core i7-3930K, like the current regular six-core Core i7-980/970, is also priced at US$583.
The Core i7-3820 will replace the same quad-core Core i7-960/950, which also costs $294. Interestingly, this is also the price of the Core i7-2600, which is slightly cheaper than the Core i7-2600K.
If no accident, Core i7-3000 series processors and supporting X79 chipset will be released in the fourth quarter of this year, but the first model is only the Core i7-3960X, Core i7-3930K two six-core, four-core Core i7- 3820 I don't know why it's going to be a little delayed.
Intel's next-generation high-end processor LGA2011 Sandy Bridge-E today sent two precise messages, one is the specific price of the three models have been identified, and the second is about the radiator.
