When Intel unveiled the 8 generation processor in August 8th this year, it is a coincidence that it is clear that the life cycle of this generation of core chips will cross three architectural innovations, which is a stress measure under the pressure of the market, but will undoubtedly help consumers get more competitive products.

In these three architectures, the generation of Coffee Lake, the generation of the first "fireman" Kaby Lake-Refresh architecture, is more likely to be the backbone of the 8 generation of rug. Now what is the performance of the Coffee Lake Processor?

The process is better and the frequency is higher

Before the 8 generation, Intel's "i7 4 core, i5 dual core" positioning has been extended for many years, but this year the old friend AMD Ryzen series has posed no small threat to Intel. In addition to the high mononuclear performance of Ryzen, Ryzen is more critical to provide more physical core than the same class processor of Intel.

As a result, a "nuclear war" struck, Intel quickly launched the Kaby Lake-Refresh architecture of the notebook processor at the mobile end, directly adding two physical core of each level processor, and the improvement of performance was immediate.

After stabilizing the footing, Intel in the desktop platform replacement, one step in place with the Coffee Lake architecture, in fact, not because of the sudden attack on the AMD, Coffee Lake should be the orthodox 8 generation of cruel, Coffee Lake on the desktop platform has been developed for some time, so the maturity of the technology is relatively simple to increase the core The Kaby Lake-Refresh has a greater optimization.

Intel's 14nm manufacturing process, as early as the sixth generation of Skaylake, published in 2015, has been applied, optimized on the 7 generation of Kaby Lake as 14nm+ technology, and to 14nm+ on Coffee Lake, which is the last 14nm process of Intel.

In a word, the greatest advantage of the process update is the "lift efficiency ratio", allowing the processor to maintain the same or lower energy consumption in the case of better performance. According to the official data of Intel, the Coffee Lake architecture, compared with the 6 generation core, improves the performance by 26%, and the overall power consumption is reduced by 52 under the same performance. %.

Another advantage of process optimization is that the processor has a higher frequency, the main frequency of the Coffee Lake architecture has been greatly improved, the single core frequency of the highest 8700K model reaches 4.7GHz, and the i5 and i7 models are also increased by the 200MHz.

In conjunction with the core graphics and memory controllers, the integrated display core has increased the frequency of the 50MHz (but it is believed to buy this level processor not a few of them), and to start a native DDR4 memory that supports 2666mhz.

Of course, Intel also moved a little bit carefully, Coffee Lake processor can only match the latest 300 series chipset motherboard, but the cost is much higher.

I7-8700K measured, Coffee Lake most strong tone

This is a long story. This year, a lot of video resources have been accumulated, and the idea of learning video editing is sprout. Double eleven chopped on the platform.

  The current list of Coffee Lake core processors on the market is like the following figure, when the i9 series has not been updated, i7-8700k actually plays the role of the flagship, the default frequency 3.7GHz, and the 12MB cache, are the strongest in the Coffee Lake family.

  In the familiar GeekBench link, i7-8700K runs out of a single core 5600, a multi core 24000 score, which is nearly twice as much as the multi core score of the 2017 iMac 27 inches in our test this year, even if the iMac Pro of the 8 core, the most powerful processor, is leaked.

  In the CineBench test that is closer to the daily use requirements, the CPU score of i7-8700K is 1449cb, and in the CineBench rankings, the 12 core or even 16 core processors are on top of the test performance.

More intuitively, the performance of the processor is about 2.6 times that of the 27 inch iMac in 2017, equivalent to 4 times that of the 13 inch MacBook Pro in 2017.

What's the use of high performance CPU? In fact, in a subtle way, we are enjoying the benefits of operational enhancement, the increasingly powerful processors on mobile devices that let the content of the mobile phone turn from other words to full images, and of course will soon be in the age of video.

The same is true for PCs, and for the next generation of games, represented by the 4K video post-game and Jedi Escape, the need for improved arithmetic is urgent.

  Both in the video decoding related X264 FHD Benchmark, or in the game related 3Dmark, the performance of i7-8700K shows that it is ready, and almost omnipotent state is exactly the same as its location.

  Even if your computer doesn't install these complex testing software, you can also compare the performance tests built in WinRAR to see how much the performance of your PC and the current leading processor can be.

Recognize the model, Coffee Lake mobile version will be

As it has been said before, the 8 generation of the core is likely to enter the three generation framework in January next year. For consumers, it is necessary to choose the product of the updated architecture as much as possible.

After nearly 4 months in the Kaby Lake-Refresh notebook processor, the family of notebook processors in the Coffee Lake architecture is coming.

The current model is all standard voltage processor, that is to say, light and short time still can not use this product, in addition to the model of I3 is four core, the other series are 6 core products.

What is more noteworthy is that there are also products of core i9.

If you have recently purchased the high performance notebook, please wait a moment and identify these products.

Processor architecture and the core number of quietly upgrades, invisible to bring a new imagination of computer computing performance, before the more laborious VR, AR and other applications, from next year may be greatly reduced the threshold, and you now "Internet, documents do not card ah" electroencephalon, perhaps next year will not be happy to follow The children were playing.

Changing computers, maybe next year, should be on the agenda.
