I7-8700 VS Ryzen 7 2700 Who is stronger？ The fierce fight between the sub-flagships!

　　[PConline evaluation]Among the newly released Intel and AMD processors, the author Xiao Bian found that the models with K or X suffixes are often more popular among consumers on major e-commerce platforms, but in fact Xiao Bian believes that the processor models without suffix are not as high as those with suffixes, and their performance is not as strong as theirs, but in fact they also have outstanding models. Today, let’s follow Xiaobian to learn about the charm of i7-8700, i5-8600, Ryzen 7 2700 and Ryzen 5 2600.

　　I7-8700 is the second flagship model of the 8th generation Core home platform. Compared with i7-8700K, both specifications are 6 cores and 12 threads, but the frequency setting of i7-8700 is much more conservative, with the basic frequency of 3.2GHz and the maximum turbo frequency of 6 cores of 4.3GHz. The highest core frequency of a single core is 4.6GHz, while the three frequencies of i7-8700K are 3.7GHz, 4.3GHz and 4.7GHz respectively. Thanks to the lower frequency setting, the thermal design power consumption of i7-8700 is only 65W, which is very low. So is it actually a small expert in energy saving and emission reduction? We will have related tests next.

　　The i5-8600 is the second highest rated i5 of the 8th generation Core. It is designed with 6 cores and 6 threads. Compared with the older brother i5-8600K, its basic frequency is 0.5GHz lower, only 3.1GHz, while the highest core frequency and the highest core frequency are 4.1GHz and 4.3GHz, which are consistent with the i5-8600K. Therefore, its thermal design power consumption is only 65W. Compared with i7-8700, its frequency design is more conservative, and it is believed that the power consumption will be further reduced.

　　AMD released the second-generation Ruilong in April this year, but only two processors in the second-generation Ruilong have no suffixes. One is this Ryzen 7 2700, which is also the second flagship model of the second generation Ruilong. Ryzen 7 2700 has a fundamental frequency of 3.2GHz, and the highest acceleration frequency of a single core can reach 4.1GHz, with a wide span. At the same time, its TDP is only 65W, which is very surprising for an 8-core and 16-thread processor. Another surprise is that, unlike the flagship model Ryzen 7 2700X, this processor has only 200 poor reviews on the JD.COM platform. What caused consumers to abandon it? Is it performance or price? Don’t worry, xiaobian will take you to explore the answer in the actual measurement later.

　　Ryzen 5 2600 is another processor without suffix in the second generation Ruilong, and it is also a low-power processor with TDP of only 65W. Ryzen 5 2600 is designed for 6 cores and 12 threads, and is built by Grofonde’s 12nm process. The fundamental frequency is 3.4GHz, and the highest acceleration frequency can reach 3.9GHz.

　　From the chart, we can see the detailed specifications of the four processors to be evaluated today. The models on Intel side generally have higher frequency and built-in nuclear display, while those on AMD side are cheaper and open to overclocking.

　　Next, let’s take a look at the changes of these four processors compared with the previous generation.

　　Due to the change of market competition, the 8th generation Core no longer squeezes toothpaste as before. From the table, we can simply see that the 8th generation Core has improved a lot compared with the previous generation. In the face of Ruilong’s multi-core offensive, first of all, the specifications of the 8 th generation i7 and i5 are compared with the previous generation.There are two more coresAlthough there are more cores, using the updated 14nm++ process can make more cores.The frequencies of i7-8700 and i5-8600 are slightly higher than the previous generation.At the same time, the thermal design power consumption of the processor is still maintained at 65W. In addition, the three-level cache of CPU has been increased a lot to adapt to more cores. In terms of nuclear display, i7-8700 and i5-8600 use HD630 vest nuclear display UHD630, which only improves the frequency by 0.05GHz, which is better than nothing, and the memory support is also upgraded from 2400MHz to 2666MHz.

　　Although the specifications and performance have been improved so much, the starting price of i7-8700 and i5-8600 is not much higher than that of i7-7700 and i5-7600, and now the actual price is only 200~300 yuan, so there is no price increase.The 8th generation of Core is the most conscientious generation in recent years.. A detailed technical analysis on the 8th generation Core canClick here to view past articles.

　　Unlike Intel’s 8th generation Core, which was hastily launched to cope with Ruilong, the 2nd generation Ruilong is obviously the product of AMD’s plan to iterate over the 1st generation Ruilong. The product uses GF’s 12nm process to make up for the shortcomings of the 1st generation Ruilong, but the TDP is still 65W. At the same time, the smarter Precision Boost 2 acceleration technology and XFR2 dynamic spread spectrum technology are used, which can make the core of the processor run at a higher frequency as much as possible, so that the processor is still excellent in applications with poor multi-core optimization.

　　In addition to the low frequency, another area criticized by the first generation Ryzen processor is the memory delay, so the focus of AMD optimization on Zen+ architecture is the cache and memory system. L1 cache delay is reduced by 13%, L2 cache delay is reduced by 34%, L3 cache delay is reduced by 16%, and memory cache delay is also reduced by 11%. At the same time, the frequency supported by the memory controller is improved, reaching 2933MHz.

　　These targeted improvements have greatly improved the second generation Ruilong compared with the first generation Ruilong and made it more mature in more applications. Want to know the detailed technical analysis of the second generation Ruilong canClick here to view past articles..

　　After comparing the improvement of these four processors compared with the previous generation, let’s enter the actual measurement link.

　　As usual, go to the test platform first.

　　In order to make the test results more objective, in addition to the motherboard and processor,We are consistent with other accessories, and the motherboard also uses ROG HERO series motherboards from ASUS, and all of them use the latest BIOS..

AMD platform

　
Willamette

　　In terms of memory, because the highest frequency that the two platforms officially claim to support is different, the memory frequency of the two platforms is not the same.It is 2933MHz on AMD platform and 2666MHz on Intel platform.

　　Memory We use the flame gun memory optimized by Zhiqi for Ryzen. When X.M.P is turned on, it can easily reach the frequency of 3200MHz, and the adaptability of the memory is also very good.

　　When testing, the motherboard BIOS is set to the full default optimal state, and then the memory frequency is changed, and other options remain unchanged.

　　Let’s first test the theoretical performance of the processor. The following tests can detect the processor in different ways.manyThreaded computing performance and single-threaded computing performance.

　　Fritz Chess Benchmark is called chess software in Chinese. You can know your processor’s computing performance by measuring the number of chess steps calculated by the processor per second.

　　WPrime is a software that tests the computing power of computers by calculating prime numbers, and has been widely used in the performance testing of processors all over the world.

　　CPU-Z is a well-known CPU detection software, and it is the most used software to detect CPU. Its own Benchmark can accurately judge the multi-core performance and single-core performance of CPU.The version of CPU-Z adopted this time is 1.85..

　　3Dmark is a software specially designed for measuring the performance of graphics cards by futuremark Company, and it has released 3Dmark99, 3Dmark2001, 3Dmark2003, 3Dmark2005, 3Dmark2006, 3Dmark vantage, 3Dmark 11 and The new 3DMark. Now, 3Dmark is not only a software to measure the performance of graphics cards, but has gradually turned into a software to measure the performance of the whole machine. 3DMark’s test physical score can be basically calculated.Actual game performance of CPU.

　　Summary of CPU theory test:The results of this evaluation are also consistent with the previous evaluation results of Ryzen and Core para-processors. Ryzen is superior in multi-thread testing because of the higher specification of para-processors, and Core processor is stronger in single-thread testing because of its higher frequency.

　　Breakdown, in the comparison between Ryzen 7 2700 and i7-8700, i7-8700 won the chess operation and CPU-Z single-thread test, while Ryzen 7 2700 gained the advantage in the other three tests, and there was not much difference between them in the test, which can be described as a tie, diamond cut diamond.

　　In the comparison between Ryzen 5 2600 and i5-8600, because Ryzen 5 2600 has six more threads than i5-8600, four of the five theoretical tests have won, and most of them have a big lead.

　　Now that the theoretical performance of the processors is known, what is the working efficiency of these four processors in practical application? Next, Xiao Bian will test the performance of the processor in practical application with the software that everyone will use in life.

　　CineBench R15 is a convincing test system for CPU and graphics card. The Cinema 4D special effects software engine developed for film and television industry is used to test a 3D scene picture with high precision, which can support up to 256 logic cores. In addition, the new version also strengthens the investigation of shaders, anti-aliasing, shadows, lighting and reflection blur, and the detection of CPU performance is more accurate.

　　WinRAR is one of the most commonly used compression software. You all know how high it requires the performance of the CPU. The stronger the performance of the CPU, the faster it is pressed and the shorter it takes.

　　Let’s compress a 2.66GB file and see how much time they take.

　　X264 FHD Benchmark can effectively test the floating-point operation performance of CPU and the actual file-changing ability of multimedia audio and video.

　　The testing significance of POV-Ray is similar to that of CineBench R15, and it also represents the 3D rendering performance of CPU. The more pixels rendered per second, the stronger the performance.

　　Video export, like WinRAR above, consumes huge CPU resources, and friends who specialize in video have extremely strong demand for this performance. We will let them export the same video, with the same video parameters and total recording time. There will be two export formats, one is the H.264 format which is more commonly used and should be the most widely used, and the other is the H.265 format which is more efficient in updating compression but has less application scope.

　　Summary of professional software testing:Generally speaking, in the professional application software test, the four processors have their own advantages and disadvantages in the comparison, which is equally divided.

　　To break it down, let’s first look at the comparison between i7-8700 and Ryzen 7 2700. When using CPU for 3D rendering, Ryzen processor will have a greater advantage because there are more cores and threads. Although i7-8700 is stronger in single-core rendering, no one actually uses only one core for rendering, so this project is of little significance. In the aspect of audio and video transcoding, there is not much difference between them when exporting video to H264 code, and i7-8700 is slightly stronger, but i7-8700 has an overwhelming advantage when exporting H.265 code, because in the latest version of X265 decoder, Intel’s native AVX 256-bit instructions are fully optimized, while Ryzen series processors do not have the native AVX 256 instruction set. It must be split into two 128-bit instructions for execution, so the efficiency is much lower. We can see that even the i5-8600 hangs Ryzen 7 2700 in this test. In other tests, there is not much difference between the two.

　　In the comparison between i5-8600 and Ryzen 5 2600, it presents another situation, which is the same as the theoretical test result, because Ryzen 5 2600 has twice as many threads as i5-8600, and it has the upper hand in most application tests, except the H.265 transcoding mentioned above.

　　Therefore, when you buy a processor, you should look at what you will often use in your daily use. If it is 3D rendering, it is wise to choose Ryzen processor. If you often need video transcoding, i7-8700 is obviously a better choice.

　　Of course, the CPU test is inseparable from the game performance. Tomb Raider 10, Wizard 3: wild hunt, Whole Territory Blockade and Ghost Action: Wilderness are selected for the project, all of which have 1080P resolution and the highest special effects. The colorful iGame1080 Flame God of War is selected for the graphics card to ensure that the graphics card will not become a test bottleneck at 1080p resolution.

　　Summary of CPU game performance test;We can clearly see that the optimization of multi-threading in 3A masterpieces is still not very good. The performance of i7-8700 and i5-8600 is not much different, and so are Ryzen 7 2700 and Ryzen 5 2600.

　　Therefore, with higher frequency and stronger ipc, the 8th generation Core won the game performance test, but the gap between the four processors is very small.

　　Since it is impossible to test the power consumption of a certain hardware separately, the following are all the power consumption of the whole machine, which are three application scenarios. The game is fully loaded with the peak power consumption of the whole machine in the process of Tomb Raider 10》Benchmark, while the CPU is fully loaded with Prime95 running FPU baking machine test and the graphics card is empty.

　　In order to ensure the stable operation of the whole machine, we use the MVP P850 power supply of Hangjia, which has passed the 80PLUS white gold medal certification and is located at the top of the power pyramid.

　　We can see that the power consumption of Core is obviously higher than that of Ruilong. After all, the frequency of Core is also higher. Intel will officially set the maximum core frequency and the maximum core frequency of a single core, from which we can know that the full core frequency of i7-8700 is 4.3GHz and that of i5-8600 is 4.1GHz when the CPU is fully loaded.

I5-8600 baking machine

　　The same is true in the actual baking machine, but we can still see some problems. Why is the power consumption of Ryzen 5 2600 higher than that of Ryzen 7 2700? This is actually related to the processor frequency. So what’s the frequency of baking machine in Ryzen processor?

Ryzen 7 2700 baking machine

Ryzen 5 2600 baking machine

　　We can clearly see that the full-core frequency of Ryzen 7 2700 roaster is 3.425GHz, while that of Ryzen 5 2600 roaster is 3.675GHz, which is 0.25GHz higher than that of Ryzen 5 2600, so it is not surprising that the power consumption is relatively high. Therefore, we can draw two conclusions. One is that the accelerated frequency policy of Ryzen 7 2700 will be more conservative than that of Ryzen 5 2600. The other is that for the second generation Ryzen processor, the increase of frequency is more likely to cause the increase of power consumption than the increase of core.

　　In the choice of radiator, in order not to reduce the frequency of the processor, we use the relatively high-end air-cooled overclocking three Donghai hegemony. The radiator is a 6-heat pipe dual-fan radiator, and theoretically four processors with TDP of only 65W should be enough. Let’s take a look at the temperature performance of the four processors under this radiator. The room temperature was 25 degrees Celsius during the test.

　　With the same radiator, the Ryzen 7 2700 with the most cores but the lowest frequency has the best performance. No wonder Acer has stuffed the Ryzen 7 2700 into the notebook, and the excellent temperature performance of Ryzen 7 2700 and Ryzen 5 2600 is also very suitable for DIYer to buy them to assemble high-performance ITX hosts. Let’s take a look at Intel again. Although the thermal design power consumption of the i5-8600 and the i7-8700 is 65W, it can be seen that the temperature difference between them is quite obvious. The performance of the i5-8600 is still normal, while the i7-8700 has a core-wide maximum frequency of 4.3GHz consistent with the i7-8700K, and the temperature reaches a relatively high of 87.Therefore, users who choose i7-8700 should pay attention not to neglect the purchase of radiator just because its thermal design power consumption is only 65W..

　　Based on the above performance tests, including 16 tests of theoretical performance, professional application performance and game performance, we can get the following comprehensive performance ranking chart.

　　I7-8700 won the battle between the second generation Ruilong and the eighth generation Core flagship with a slight advantage, while Ryzen 5 2600 helped the second generation Ruilong regain a city. Of course, our tests in this paper are all carried out at the default frequency, while Ryzen series processors are all frequency-unlocked. In the previous first test of the second generation Ruilong, we have tested that the overclocking ceiling of the second generation Ruilong is between 4.2 and 4.3 GHz, and the performance of Ryzen processor after overclocking is also acceptable.Click here to view past articles..

　　This is the ranking of the four processors in this paper in our new version of PConline CPU ladder diagram. The above picture is a brand-new interactive CPU ladder diagram released by PConline, which includes linked e-commerce price, related original articles, parameter comparison, ranking comparison and performance comparison. Users who need it will collect it soon, and there will be ladder diagrams such as graphics cards and notebook processors released one after another in the future.

　　Let’s summarize the situation at Intel first. Because i7-8700 has the same full-core turbo performance as i7-8700K, the performance difference between them at the default frequency will not be very big. Moreover, due to the rising specifications of the 8th generation i7, the heat and power consumption are relatively high. In other words, the cost of overclocking i7-8700K on the radiator, power supply and motherboard will be relatively high. For consumers who are not very keen on the ultimate performance, i7-8700 that can be used with B360 motherboard is undoubtedly a better choice.

　　As for the i5-8600, because of its high pricing, its performance will not be very outstanding compared with Ryzen 5 2600 or its younger brother i5-8500/8400, and its power consumption is also high, and its temperature is high. Xiaobian thinks that the purchase value of this processor is relatively low.

　　On the AMD side, we can see from the above evaluation that Ryzen 7 2700, the sub-flagship, actually has its own advantages in comparison with the 8th generation Core sub-flagship i7-8700, so why is its sales volume so low? This can only blame its big brother Ryzen 7 2700X. Ryzen 7 2700X has stronger performance, and a new belief RGB ghost radiator is presented, but it is only 200 yuan more expensive than Ryzen 7 2700, and most consumers will choose the flagship Ryzen 7 2700X with higher standards. Nevertheless, we can still see an outstanding advantage of Ryzen 7 2700, that is, excellent temperature and power consumption performance, which will be particularly prominent in notebooks or when building ITX hosts. We can expect more manufacturers to directly put this processor into notebooks in the future. However, there are only a few consumers with this demand. We can also foresee that if AMD does not further adjust the price of Ryzen 7 2700, the audience of Ryzen 7 2700 will be very small for a long time to come, and the sales volume will not change much.

The radiators of Ryzen 7 2700 and Ryzen 5 2600 are different, and the materials are better.

　　As for the Ryzen 5 2600, it has gained the upper hand compared with the i5-8600, and it also has certain advantages in temperature and power consumption. More importantly, the Ryzen 5 2600X, which is 200 yuan more expensive than it, does not give away the temptation to believe in the RGB ghost radiator, so this processor has a fair sales volume. When it comes to overclocking, Ryzen 5 2600 can easily exceed 4,0GHz, but whether it can exceed 4,2GHz depends on the face. Although it is 200 yuan cheaper than Ryzen 5 2600X, the highest acceleration frequency of Ryzen 5 2600X single core can reach 4.2GHz. If the temperature and power consumption are not too high, Xiao Bian still recommends everyone to buy Ryzen 5 2600X.

　　In the choice of Ruilong and Core processors, it is necessary to choose according to the needs of the readers. For example, it is more wise for netizens who often use 3D renderers who are very concerned about the temperature of power consumption or to use Ryzen 7 2700 or Ryzen 5 2600 naturally, but for consumers who often need video transcoding, especially H.265 format transcoding, it is more efficient to use i7-8700. Of course, what we discuss in this paper is based on the price of JD.COM’s self-operated platform on July 13th. If the original price of i7-8700 is three or four hundred more expensive than that of Ryzen 7 2700X, its purchase value will be greatly reduced.
