[PConline evaluation] Two years ago, Intel used to bounce for five generations of Core Duo to save the market, introduced a default 4.0GHz high-frequency Core i7-4790K, although it is Refresh version, but it is known as high-frequency "big killer." . Tick-Tock's rhythm at this time was merely a matter of fact, and Intel later reluctantly announced that Tick-Tock couldn't move and needed further "optimization." The protagonist of today's evaluation is the Core i7-7700K that belongs to the “optimization†step in the 14nm era! At 1 o'clock on January 4th, the ban was lifted!
As a highly dynamic DIY concern you may have probably guessed performance Core i7-7700K, I suggest you jump directly to the ancient i7 overclocking tests and test parts of the same frequency. If you want to fully understand this generation of Core Duo or honestly read the article.
â— First draw a key: 7-generation Core compatible 100/200 system board
According to Intel's previous upgrade routines, the new generation of Core Kaby Lake can be compatible with 100/200 series motherboards. The 100 series motherboard can be upgraded to support the new CPU by simply flashing the BIOS. In fact, the 6/7 generation Core Duo compatible 100/200 series. Motherboard, of course, the ideal "car" as standard for the new CPU is the 200-series motherboard.
This evaluation will use Gigabyte to create a new AORUS gaming brand Z270X-Gaming 9 motherboard
200 Series motherboard and the new Core will ban together, we PConline will be the first time to synchronize the first test, I would like to know more first test 200 series motherboards can enter the portal.
Speaking of 200-series motherboards, here is a brief sentence: With 200 series motherboards, the number of PCI-3 channels will be open to 24, and it can also support the black technology optane hard disk technology, talked about the optane hard drive technology is indeed cattle B, philosophy Very advanced! The memory and hard disk are combined into one, and the performance is also very good. The official data is the level of rolling SSD. But in fact this stuff hasn't really arrived yet, and it's also facing enterprise applications. Intel's joining the 200 series motherboards just means it can support it, leaving you with a future or maybe you have a chance to use it. (PS: Now sell the concept first)
â— What did the 7-generation Core Laby Lake improve?
Although 7th generation Core Duo has a nice name called Kaby Lake, it is more like Skylake Refresh in the eyes of many old players! The same process, the same core architecture, the same LGA1151 interface, and the new generation of Core i5/i7 are all on the basis of the original 6th generation. It's really hard not to remind people of the Devil Canyon that was launched 2 years ago. Series (Haswell Refresh). Hard to find different words can only say that the Devil Canyon is mainly for the Core i5/i7 upgrade, while the new generation Core series is more to strengthen the Core i3/Pentium two entry series specifications, i3 joined the overclocked version, Pentium to join the super Threads.
Optimization is a 7-core Core tag, and the increase in frequency is the main embodiment of Intel's optimization. As the 7th-generation Core i7-7700K, the highest-profile Core i7-7700K frequency starts directly from 4.2GHz, and the single-core maximum frequency reaches 4.5GHz, dual-core and triple-core. The quad-core can also be clocked to 4.4GHz at the same time! All of a sudden, the voices that dropped from the 4th generation to the 6th generation dropped.
In addition to the increase in CPU frequency, the new generation of Core Memory Controllers has also been slightly upgraded, moving from the default support of DDR4-2133 to a small step forward to DDR4-2400, in order to meet the needs of the current mainstream DDR4 frequency. However, honestly speaking, the small increase of 2133 to 2400 is just like the name “toothpaste factoryâ€. This year, memory manufacturers are actively launching high-frequency (2800, 3000) DDR4, and high-frequency DDR4 is everywhere. The CPU's memory controller has been conservative... this is really true.
High-frequency DDR4 is everywhere, the CPU's memory controller is still relatively conservative
â—The desktop version of the checkup is "It's equal to no increase"
In the "7th generation Core i5-7600K sneak test", we have found that although the 7th generation desktop version of the nuclear model "upgrades" the HD 630, it actually continues to use the Gen 6 architecture for 6 generations. Substantial improvement. Therefore, we can foresee Core i7-7700K's nuclear readiness in this evaluation has been ready to "armored"! ?
There is no real improvement in 3D performance, but there is no improvement in the 3D performance. It is a lot of improvement in the soft power, including the media engine, support for 4K ultra high resolution, support for HDCP 2.2, support for HEVC 10-bit and VP9 encoded video, etc. Such as, improve the efficiency, but also more power. For the mobile world, it seems like he has added a battery life "Buff."
â— As for overclocking and temperature, we all say that it is an overclocking weapon but at the same time it is a small stove?
Before the official ban was lifted, the 7th generation of Core Duo had already flowed out of various fancy sneak hooves on the Internet. Universal tests showed that the new generation of core physique is better and the overclocking potential is strong, especially the protagonist Core i7-7700K of this evaluation. Can limit overclocking to 7GHz, air cooling conditions easily on 5GHz.
While everyone is doing all sorts of overclocking happily, it's actually a small stove. ! The reason is attributed to the CPU inside the "residue" grease head, and even called for the people to open the lid.
In order to further verify this issue, in this evaluation, we also added the same frequency, the temperature of the same voltage in addition to the overclocking test. Is this generation of silicone grease even more slag? The following evaluation will be announced for everyone.
â— catch VR trend? Outer packaging more VR
In 2016, the entire industry was playing VR cards. As long as VR and VR are involved, VR will be a matter of course. Intel, who has always understood the promotion, will not miss this opportunity. In the basic premise that the six-generation color palette is basically used. Next, the logo of the VR is printed on the front of the package, and the “For a Great VR Experience†explanation is also attached.
For the promotion of the highlights of the 7th generation is not much, for the promotion, printing LOGO can be described as a mentality (biao) home!
â— Appearance comparison: the same foolproof mouth, not the same cover
Although both use the same LGA 1151, the supported motherboards are compatible with each other, and the fool-proof mouth is naturally a uniform position. The PCB substrate is also light and thin. If it is to be distinguished from the appearance, it can be distinguished from the CPU cover. The cover of both the upper and lower ends of the new generation of Core Duo are "convex" and the overall vision is stretched.
â— Look at the parameters after the appearance of the contrast it
The 7th and 6th generation Core i7 specifications have a very high degree of similarity. The same process, the same core, can only be distinguished from the basic frequency, core frequency and memory frequency support. Well, this is an enhanced version of Skylake. So silent performance comparison of the frequency of words, 7 and 6 generation gap generations mainly from the difference in frequency, if compared with the frequency, it can be said that there is no difference in performance.
How often does the silent frequency gap? There is no difference between the same frequency? The following comparisons were immediately conducted for everyone's review.

â— Evaluation platform and method description
This evaluation mainly from the CPU, GPU performance, power consumption compared to three aspects, in the CPU performance evaluation, we added additional tests: air-cooled overclocking and previous i7 frequency 4GHz (off Rui frequency) performance as a reference. In terms of competitors, since AMD Ryzen has not yet released, taking out the old FX series out of the "whiplash" has no practical significance. Therefore, this evaluation is not currently added to AMD for comparison. A comprehensive comparison and evaluation is reserved for Ryzen's official release.

1, GPU performance test:
Although just as a GT2 level HD 630 nuclear display, for the previous generation of HD 530 GPU more serial numbers on the promotion, the overall performance of the same preservation, the following look at HD 630, HD 530 two nuclear performance comparison.
â— GPU performance test project
Test summary: The same display core, plus the same GT2, HD 630 and HD 530 performance gap is very small, due to the higher frequency of the 7700K, so the general game results must be a little more pointed.
2, CPU performance test:
â— CPU theory multi-threaded performance
â— 3DMark series physical operation test
â— Common software performance testing
â— Professional software performance test
Test summary: simply comparing the CPU performance, i7-7700K compared with i7-6700K is still about 5-7% performance, the core architecture is unchanged, the overall performance is basically the same, more is the difference in frequency reflect the level.
â—CPU game performance test
Test Summary: CPU-sensitivity of the singularity of the Ashes and Crysis 3 this type of game, CPU frequency has a greater impact on the game, the more dominant 7700K frequency performance is even better. But for Tomb Raider 10 that does not eat CPU, it is difficult to reflect the difference.
3, platform power consumption comparison test
Test summary: The new generation of i7 is 91W because TDP and the previous generation, so the performance of power consumption is basically the same.
4, additional tests: i7 with the frequency 4GHz test
The improvement of the 4GHz CPU architecture energy efficiency at the same frequency really reflects that the 6th and 7th generations of the same frequency performance are basically at the same level, and the performance of each generation of the same frequency performance after the 3rd generation starts to decrease, and the cumulative increase in 7 years is only 30%. In the three Tock years, the same frequency performance of each Tock year structure is about 10%.
5, additional testing: overclocking test and temperature comparison
Overclocking: After repeated overclocking over and over again: In the final air-cooled condition, the pressure 1.444V stabilized over 5.1GHz. Compared to the first test of 6700K, 1.376V stabilized over 4.7GHz, the voltage of 7700K dropped a lot, but the frequency was not improved. Less, more potential for overclocking!
Temperature performance: under the same conditions of the pager, the four cores of the 7700K will reach 87 degrees or more at the default frequency (after the OC is broken by 90 degrees is not a problem), which is at least 17 degrees higher than the six cores of the 6700K! ? The average temperature is also higher by 20 degrees! ? To become a new generation of small stoves, it is ultimately necessary to equip with a high-end air-cooled or even water-cooled radiator in order to achieve good pressure.
As for the reason for the high temperature, there are 2 possibilities: 1. The motherboard BIOS is not yet complete; 2. The internal silicon grease in the CPU has shrunk. If it is the first case, it is still relatively easy to solve. Waiting for a new BIOS update is good enough. The most fear is the second one. I am afraid that it is necessary to open and replace the grease in order to effectively solve it.
6, PConline evaluation room summary:
Performance: The same-frequency performance is maintained at the level of the previous-generation Skylake, and the performance improvement comes mainly from Intel's "optimized" high frequencies. With the increase in frequency, the overall performance is improved by about 5%, and this time the toothpaste is squeezed even more slowly. If you want to squeeze a little more, you need to start a super-frequency, overclocking much stronger than the previous generation!
The nuclear display...Vest
On the power consumption: power consumption is basically the same as the previous generation, but the actual temperature of the thermometer is not very satisfactory, the overall temperature ratio is much higher than the 6700K, it can be expected that this 'temperature' but also blowing up an open boom.
On the price: the new generation of Core Duo officially listed is to wait until January 6 before selling, but a omnipotent treasure has been stolen for a long period of time, although the price is high, the new listing of the same price is also the case, as long as no listing of the 6700K In the initial period of large-scale out-of-stock, the price is basically to maintain the current price, only after a large-scale distribution after the year may be reduced.
â— 7-generation Kaby Lake's market positioning?
Starting 7 daikurui totaling KabyLake 16, including Xeon E3-1205 v6,3 Core i7,7 paragraph paragraph paragraph Core i5,2 Core i3 and Pentium 3. Only for the first time in recent years, the Core i3-7350K, which is the first to open the multiplier, is not on the starting list. It is a pity. The rest of the product line is sufficient to fully replace the existing Skylake products in the market. Having said that, from a performance point of view, Intel's urine is added. The sale of 6 Skylakes in the market in 2017 will not be overdone, and the 6th and 7th generations will also coexist for a long time.
In the face of rival Ryzen's challenge, 7th generation Core Duo is the main confrontation product. As a consumer, of course, AMD Ryzen can bring pressure to Intel, forcing a price adjustment in the near-monopoly CPU market to bring more favorable products.
