Intel new Core i7 Extreme the core breakthrough in the 3GHz speed of mark

Intel has begun delivery of 21 new processors designed for laptops and desktops, including the new Core i7 chip, the reference clock frequency of 3GHz, hit a new high speed mobile processor based on the Ivy Bridge microarchitecture.
4-core Core i7-3940XM Extreme Edition will replace the Core i7-3920XM, the latter a clock frequency of 2.9GHz. According to the price of Intel released Saturday, Extreme Edition chip is priced at $ 1,096 from the grant in 1000, compared with the 3920XM, the price does not change.
Extreme Edition chip is mainly used for the game version of the laptop, Intel's highest performance mobile processor. Intel and its rival AMD generally will increase the clock frequency of the chip so that claims to be the king of the performance.
Depending on the application, the higher clock frequency may improve performance, the clock frequency will increase With the reduction of the chip size, the leak will be reduced, said Jim McGregor, the founder of the consulting firm Tirias Research.
Increase the clock frequency also make chips more energy consumption, thereby reducing the time and life of notebook battery life, McGregor said. Only a very limited part of the user, for example, to require such performance gamers. For the pursuit of higher performance-per-watt manufacturers is to increase the number of cores, this practice so far has been the development of the decade.
"With multi-core, the frequency has become a secondary issue," McGregor said.
However, users quite this obsession of people, they always think that the clock frequency is very important to enhance chip performance, McGregor said.
"We still GHz or the number of cores obsession, because we are simple-minded consumers, we need the figures to convince themselves, but in fact, the clock frequency is really not so important," McGregor said.
The new Ivy Bridge chip has a feature called Turbo Boost, each core clock frequency which can be based on the required performance increase or reduce. This feature in the Core i7-3940XM Extreme Edition also need the right performance, the main intent is to provide for a specific application.
Intel Core i7 processor clock frequency to improve the thin and light mainstream notebook. New 4-core Core i7-3840QM reference clock frequency of 2.8GHz, compared to before the fastest chip, the 2.7GHz Core i7-3820QM also reached a new high. Both chips are priced at $ 568.
Intel also began to be delivered for the new desktop Core i3 and i5 Ivy Bridge processor, dual-core Sandy Bridge Celeron processors for low-power notebook.
