Let's embark on a short journey in time, just 10 years back for summer of 2005. Rumors and articles are starting to emerge on the web on a new architecture called Conroe. Changing the brand in the doorway will bring the first processors where there is emphasis on cores, many cores. Series . The computer market is hungry for performance, the lack of which is felt on many levels, and Intel is giving gas in an innovative process of 65 nanometers.

The years 2006 to 2009 were very important years in the world of computers and hardware. In these three years the average video card is powered She managed to double herself Twice when we started with Geforce 7900GT and finished with the Geforce GTX 285, when we started with the Pentium D and finished with the Core 2 Quad Q9650. These extreme changes occurred simply because the need was there.
Since then, it seems that the demand for high processing power has been significantly reduced among PC users, at least most of them. From 2011 to the present, there has been a significant change in the approach of XNUMX Towards this market. The market was split into extras and majors with two separate seats, and the improvement in processing power was significantly less than in previous generations.

Now the emphasis is on the wider public, a concern that involves reducing power consumption and increasing the core graphics power in the processor to suit media needs such as playback And games .

As a result of the extreme improvement in power consumption and the relative power in relation to it,WALNUT And like ultra-.

The next step in evolution, the Skylike processors

Today is a day that marks another step in the progress of Towards smarter and more advanced computing with the launch of a new series called Code . This series continues the Aswell and Broadwell series of the LGA1150 chassis that we have become accustomed to in the past two years.

Similar to the launch format presented by Intel on 2011, after a series of processors are refreshed in an existing socket, a new series of processors will arrive, bringing in a new chassis. The SkyLike is no exception, and comes with a completely new processor chassis, a LGA1151 chassis with 1151 touch points (pins). These processors are manufactured in a new production process of 14 nanometers. This is compared to the 22 nanometer process we know from the aswell processors Core i7 4790K.

That's how you look at the processors The new Skylike series on the shelves. Intel seems to be putting a serious emphasis this time on branding, and is taking serious criticism of the senseless packaging of the Haswell processors. In the new packaging you will not find any coolers for the K processors. Understand that users are looking for a body Serious for such processors.

Intel - Meet the new processors

cpudetails
As I mentioned, the SkyLike processors will come with a LGA1151 chassis that is not compatible with previous generations processors, so you can not assemble a processor such as 4790K or 3770K, they just will not physically enter. At launch there are two Who go into the world's air first. God- i7 6700K and i5 6600K. The format is very similar to recent launches, but the data are slightly different.

The Core i7 6700K processor is a quad-core processor with the HyperThreading feature. This feature simulates four additional cores, giving the processor better processing capability by splitting processes and working more effectively on them. The operating frequency of the 6700K is 4 GHz, and using Turbo's technology , The operating frequency can reach 4.2 GHz. This processor contains 8 megabytes of RAM A cache with a heat envelope of 91 watts. Yes, processors Have a higher heat envelope than the Aswell, although they are manufactured in the process of producing 14 nanometers compared to 22. Later on you will also understand why.

Laboratory- i5 6600K is a little brother, and it comes with four-core processing. Traditionally, the main difference between the two is that the 6600K does not contain HyperThreading and its four cores work without further help. The operating frequency is also lower and stands at 3.5 GHz. Its Turbo frequency reaches up to 3.9 GHz. This processor carries a 6 megabyte of Same cache and heat envelope of 91 watts.

Launch prices of These are 350 USD to 6700K and 243 USD. For comparison, the prices of i7 and 4790K i5 and 4690K were respectively.

Motherboards - new chassis, new chipset, flexible memories

As befits a new chassis, the new motherboards come with a new Chipset chipset, the Z170. This chipset is soon expected to join cheaper and simpler packages.

z170complex
The chipset is actually The motherboard has its functions Many with different components. It actually helps the processor communicate with components such as hard drives, expansion interfaces, and some ports.

The new Z170 chip is very similar to the Z97 we know from the previous chassis, but has received a few facelifts. For the first time, say hi and goodbye to PCI-Express 2.0. That's it, It's over. You will no longer find 1-sized PCI-Express interfaces (2.0), and now their traffic volume has doubled and are moving to 3.0. In numbers, from 500 megabytes per second, to 985 megabytes per second. This means that small expansion cards are receiving significant traffic acceleration that will help add components that are not installed on the large PCI-Express slots. This is good news especially for the storage market. The PCI-Express 1 X3.0 interface can now be received Which burst the traditional SATA receiver on a board that is still limited to 580 megabytes per second.

Here are some of the additional features that you will find in the Z170 chip-based boards (may vary in some models): 10 USB interfaces 3.0, 14 USB interfaces 2.0, and 20 3.0 PCI Express. Motherboard manufacturers are going to use the chipset's PCI-Express routers to scatter them between the expansion interfaces, the M.2 interfaces, And maybe we'll see some more surprises.

Memories - remaining, Entered

It's been a long time since we've seen two different memory types supported on the same platform. At the end of the life of a LGA775 resident, several motherboard models with support for DDR2 and Different grooves. These memories could not work at the same time, but they gave flexibility to those who upgraded in the form of using old memories New.

With LGA1151 chassis the story is similar, roughly. Memory is supported , But as then, only in models that explicitly contain slots . Not all memory Will support LGA1151 boards with slots . Due to the nature of the new processors and their memory controllers, The only one that supports is actually DDR3L, a memory that operates at a voltage of 1.35 volts or less. So, if you have a memory At a voltage of 1.5 or higher, you will need to replace it to move to the new chassis.

Support for The new is inclusive and there are no limitations. The high-end memory, launched with the LGA2011-3 extender, has already dropped tens of percent of the price. As of this writing, 8 is gigabyte of At 2133 MHz you will receive 350-380. This, while the same DDR3L volume will cost only 10-30 less. The difference is not significant in this case. If in certain places The price of these memories is expected to decline significantly in the near future thanks to price updates.

The graphic core is an inseparable part

When she passed When LGA775 is installed on the LGA1156 chassis on 2010, it has decided that it is time to dispose of the graphics coreboards on the motherboard and integrate them into the processors themselves. Thus, we received pioneers such as the Pentium G6950, which brought with it a modest graphic core that was sufficient for simple home and office applications. Since then, works In full force to increase the graphic power as much as possible in its processors.

In this review, I will focus mainly on the Core i7 6700K processor, simply because it is the processor I received for Intel. Core i7 6700K has an enhanced graphics core called HD Graphics 530. You may find it simply under the name HD530. The graphics core frequency can reach up to 1150 MHz and graphics memory is the system memory, whether DDR3L or . For this reason, the faster the memory, the higher the core graphics performance.

How fast i7 6700K compared to the previous generation processor 4790K? How fast is the graphics core and is the investment worth it? It's time to take the performance test and find out.

Performance tests - test systems

LGA1150 System:
Core i7 Processor 4790K
Motherboard MSI Z97 Mpower Max AC
G.Skill sniper memory 2X8GB 1600Mhz

LGA1151 System:
Core i7 Processor 6700K
Motherboard ASRock Z170 Extreme6

The video card tested in the game tests is Sapphire XXUMXX9X 290GB Tri-X, Sapphire volume is M4 Pro 5GB of And the power supply is Corsair's HX 1050W. The operating system is 10 in Pro version.

Cinebench

The Cinebench test is a test where the computer system must render as fast as possible to a complex 3D scene. Rendering is performed in small pieces and distributed evenly between processor cores for maximum efficiency. A higher score means shorter rendering time.
Cinabench
The difference in this test is in favor 6700K is 3.4 percent.

WinRAR

The Winrar compression test is one of the most popular performance tests. Everything is measured here optimally. Memory, processing power and response times.
WinRAR
In this performance test, 6700K is the addition of 9.1 percentages . This is slightly more acceptable and higher than the render test, where the system memory has a lower effect.

Battlefield 4

El Game tests joins Sapphire's Radeon R9 290X video card. The purpose of these tests is to show what performance they are producing in the gaming system. The game is tested at 1920X1200 under Ultra settings.

As you can see, there is a small advantage to 6700K, how it is not significant at all

Unigine Heaven

Heaven is not a game, but a high-definition 3D display. True, it carries the DNA of new games and contains elements you will find in them like high resolution textures, advanced polygon detailing and realistic shading. Heaven also features testing tools, making it a favorite for hardware reviewers. The test resolution is 1920X1200 under Ultra Settings.
Heaven
The advantage of 6700K here too is very small and stands at less than one percent.

Metro: Last Light

The Metro Games series is based on an advanced graphics engine called A4. This graphic engine makes heavy use of the elements that DirectX11 has to offer and also comes with convenient testing tools for precise hardware testing. The processors were tested under 1920X1200 in maximum settings with normalization.
Metro
Nothing new here under the sun, less than one percent of the performance of the Metro gaming between the two processors

Power consumption

Power consumption was measured from the wall outlet. The differences presented are between the two complete test systems.
Power
The differences in power consumption between the two platforms are certainly interesting. Advanced voltage control causes 6700K to be a cool processor with extremely low power consumption at rest. However, when I ran Prime95 and let the processors process numbers without rest, the 6700K power consumption exceeded that of the 4790K

Who did you read in structured?

Another important test is the built-in GPU. To do this I separated from the R9 290X and connected the screen directly to the display ports on the motherboards.
The competition is between 4600K HD 4790 and 530K HD 6700. Remember, the built-in graphics cores use RAM memory to store graphic information. I chose three different types of tests to reflect the differences in graphic processing strengths: light play, Street Fighter IV, OpenGL and heavy game, 4.

IGPnew

In Street Fighter IV on 4790K, you can say that it is barely worn when 6700K can be said to be definitely worn. The difference between the two in this game stands at not less than 58 percent. In the Cinebench OpenGL test, the graphics power of HD 530 is also expressed with 45.8 percent difference. For dessert, I ran the 4 at 1280X720 resolution under Medium Settings. In this game, a difference of 44 is observed in favor of the 6700K and its built-in graphics core, the HD 530.

In light of these results, one can gently say that the graphics core of the i7 6700K is approaching the standard gaming capabilities of HD-Ready (or 1280X720) screens. This is a great achievement for the team of Considering that this is a separate processing unit on my back Square modern and strong cores.

Analysis of performance tests

I will begin the analysis of the performance tests with the score of the obvious. Some expected this and some waited for the performance tests. Performance difference in general between the 4790K and the 6700K is null. In fact, this is one of the performance differentials if not the "lowest" difference we have seen in the transition between different brackets. Even in the transition between 2600K and 3770K, the differences were much more dramatic.

Sandy and Abie Bridge still have no real reason to upgrade if processor performance improvement is what they're looking for, definitely. However, in tests where CPU memory is used more heavily, performance differences are significantly higher. With time and availability of memories Faster, this difference is likely to continue to grow.

As far as its core graphics are concerned, Doing it again. The 530 HD graphics core embedded in the processor 6700K is quite strong and performance improvement over 4790K's core graphic core is close to average to 50 percent. This improvement gives the HD 530 the stamp as a graphical interface that can satisfy those who occasionally want to run easy games beyond browser games or indie 2D. Maybe a bout of nostalgia will make you install 4 or Half Life 2. In this case HD 530 will not have a problem at all to run such titles under maximum settings. This graphic power is an important added value for many users and saves a lot of expense on a dedicated video card.

Yes upgrade? Do not upgrade?

The question "Should I upgrade?" Always jumps in comments and forum after launching a new platform. There is no general answer to this because it depends on the user's existing hardware and needs. In general it can be said with confidence that holders i5 from the last four generations can be calm about upgrading the system. The performance difference between 6700K and a processor like 2600K is still not quite significant. In fact, it may even upgrade from a processor like 920 will not always be a justification, depending on the reason and needs.

Either way, at the moment the LGA1150 has a few weeks before it becomes a part of the past that can not be recommended at all. Users who need new i5 and i7 processors - here's an opportunity to innovate with a new chassis and new technologies, the cash difference is not great even if you buy it with a memory type .

Which to take? Should I stay with DDR3?

First of all, it is important for me to stress again that the The only one supported on the SkyLike platform is DDR3L with only 1.35 operating voltage and not 1.5 volts. If you have such a memory with a weak and old system, it makes sense to switch to the LGA1151 board that supports DDR3L with a new processor. If you do not have a memory like this and you go to buy a new computer, invest a few dozen shekels and buy it with . You will enjoy a slightly faster system, allowing you to upgrade to memory that will be relevant at least until the end of this decade. That, instead A little cheaper that is expected to be raised and disappear almost completely later.

The future of the mainstream desktop market

It seems that Intel has been taking things slowly and confidently lately. Improving processing performance has reached the minimum possible level to call it an upgrade. In addition, it seems that everyone who takes care of electricity consumption and heat emission in the desktop market does not get products to help his concerns. Despite the dramatic transition from 22 to In the production process, the use of the two processors is similar in terms of heat and electricity.

A lot of engineering went to the graphics side of the processor. Improvement of nearly 50 percent is not going to be evident Over and over to make sure you can play with the new processors, the minimum requirements for high-quality movies and browser games have gone through four generations. the mother Aspires to gaming processors that will not require a dedicated video card, or perhaps it is preparing micro- Graphical that she will soon be planting in video cards dedicated to gamers? At the moment you can only wonder.

One thing is quite clear, there does not seem to be a serious demand today to improve processing power in the desktop market and Intel is moving comfortably in this market while taking care of other markets that are as popular as (Someone said Zenfone?), Ultras and mini computers.

Increased- 6700K will strongly recommend to anyone who is looking for Good and do not want to throw thousands on Extreme. Is the natural continuation of 4790K, at the price of 4790K and on a platform that offers a host of significant improvements.

Stay tuned for the next few weeks, when we bring you reviews on new motherboards, More and more!
