Large, perhaps even too much hope vested in the new generation of desktop processors from Intel.Promises of the company with regard to generation, code-named Skylake were generous. Here we briefly summarize them in our material, discussing chips Broadwell: "It (architecture Skylake), is expected to bring substantial productivity gains and mark the beginning of a new wireless era in the PC world - both in terms of display and relative to charging technology and data transfer ". That was then. Let's see what we have today.
As you know, Skylake not the first generation of microprocessor, using 14-nanometer manufacturing process - a "privilege" and falls on the family Broadwell, which debuted on the market at the end of last year. Almost immediately after the first wave of chips Broadwell Intel announced that models designed for specific market segments, will be postponed at least a year, maybe more. In light of this information, it was logical to assume that the company will delay the announcement of Skylake, until the market is saturated enough chips Broadwell, and only then will release a new microarchitecture. Instead, Intel released Skylake just a few weeks after the first desktop processors based on Broadwell.
Perhaps the reason for this move is related to the news of the delay Kaby Lake, successor Skylake and Broadwell, which must be produced on the new 10-nanometer manufacturing process. The company clearly has more serious difficulties in trying to follow the famous Moore's Law, while the last fifty years, used microprocessor technology closer to the inevitable limit of their capabilities.
Anyway, architecture Skylake market already fact. In addition to 14-nanometer production technology, it comes with a new microprocessor socket (LGA1151), integrated graphics core of the new generation (Intel HD 530), a new chipset (Z170) and support the new memory DDR4.
If you watch closely the development of the platform from Intel, you will immediately notice that the Z170 in fact almost identical to its predecessor Z97. The difference between them is mainly evolutionary nature.For example, the number of available USB 3.0 ports increased from 6 to 10. As a result, the new chipset supports a total of 14 USB-ports. C Z170 and also debuted a new 3.0 version of the internal DMI (Direct Media Interface) interface between the north and south bridge chipset. This increases the theoretical bandwidth connections to 2.5 GB / s to 8 GB / s (i.e. 3.2 times).
This does not mean that DDR4 is bad - on the contrary. Just to reveal the full potential of the new memory will require more time and optimization of popular programs.
A few words about the first bird out of the nest Skylake. Heavy task to pave the way for a new architecture was entrusted to two chips: Core i7-6700K and Core i5-6600K. The letter «K» in their names suggests that this CPU with an unlocked multiplier, ie they promise easy and flexible overclocking capabilities (improve their nominal clock frequency). This gave Intel the foundation to position the first two Skylake-processor as products targeted to fans of video games and enthusiasts.
That and more detailed picture of the two chips. A more productive (and expensive) one is the Core i7-6700K with four cores and technology Intel Hyper Threading (ie a total of 8 streams). The chip has 8MB cache in the third level (L3) and clocked at 4.0 GHz. Integrated into the processor memory controller supports DDR4 at 2133 MHz or DDR3L 1600 MHz.
More accessible and Core i5-6600K has four cores, but comes without the support of Hyper Threading. Its nominal clock frequency of 3.5 GHz. Less L3 cache (6 MB), and supported again DDR4 memory and DDR3L.
The recommended starting price of both processors: $ 350 for Core i7-6700K and 243 dollars for a Core i5-6600K.
Performance
The first practical texts of two chips Skylake are somewhat contradictory. Despite initial promises of generous Now Intel is himself rather conservative in their forecasts of growth performance, which users can expect from the i7-6700K and i5-6600K. According to them, Skylake 10% faster than last year's Devil's Canyon (updated generation Haswell), 20% faster than the Core i7-4770K Haswell of conventional generation and about 30% faster than the chip Core i7-3770K Ivy Bridge.
The results show that the new processor to confirm this. In some applications - while transcoding the video, rendering, and other similar heavy series of successive operations Skylake unable to show 30- and even 40-protsetnoe superiority over previous generation processors.
However, in the more common applications (including games), the growth is much more modest - in the range of 5-10 percent
With this in mind Skylake hardly particularly advantageous upgrade for users of computers with chips Haswell, or even Sandy / Ivy Bridge. Especially considering the fact that the transition to Skylake will mean purchasing a new motherboard, memory modules (DDR4) and probably cooling as LGA1151 socket has a different retention mechanism.

Details Skylake
Unfortunately, this is not part of the text information will abound, as you might expect. Probably the first time in its history, Intel launches a radically new microprocessor architecture, which is almost unknown to any specific details. The company, for example, says nothing about the number of transistors on a new chip, is silent about the physical size of the silicon wafer, is not even clear exactly what changes were made compared to its predecessor Skylake. No ordinary colorful pictures of "naked" CPU - ie Only the kernel without a protective metal coating.As you know, Skylake not the first generation of microprocessor, using 14-nanometer manufacturing process - a "privilege" and falls on the family Broadwell, which debuted on the market at the end of last year. Almost immediately after the first wave of chips Broadwell Intel announced that models designed for specific market segments, will be postponed at least a year, maybe more.

Other theoretical improvement
One of the major innovations that bring Skylake, a memory support DDR4, which in theory should provide a significant improvement in the overall performance of the subsystem CPU-RAM. We say "in theory", as compared with the new DDR3 memory offers high bandwidth but higher latency (or higher latency in addressing all the memory blocks). For example, the highest available today in the market class type memory DDR4 (DDR4-3400) at a latency specification 16-18-18-36. For comparison, the fastest memory DDR3 (DDR3-2133) can brag about latency indicator 8-10-10-27. In other words, the clock frequency DDR4 1.6 times higher than in comparable DDR3 module, but the latency of the latter is 1.6 times smaller.Given the fact that the performance of most currently used mass applications depends more on the performance of latency than the transmission rate (the bandwidth of memory), the transition to DDR4 unlikely to have immediate positive effect in this regard.This does not mean that DDR4 is bad - on the contrary. Just to reveal the full potential of the new memory will require more time and optimization of popular programs.
