i9-9900K led the three arrows together - Intel's top legion comprehensive analysis

via:快科技     time:2018/10/12 13:32:54     readed:631

Now, let's review and summarize the key highlights of these three lines and see what Intel has brought.

Vice President, Client Computing DivisionDesktopAnand Srivatsa, General Manager of Machines, Systems and Channels, gave a keynote speech

First and second generation mainstream Core: i9 brand + mainstream eight core + acceleration 5GHz + brazing heat

The ninth generation of Core Lake Refresh is undoubtedly the absolute protagonist of this time, especially the flagship Core i9-9900K. The proper star-rated products will also be the model that Intel will promote in the future.

Until the seventh generation, Intel's Core family is relatively simple, each generation or upgrade process, or update the architecture, only one set of products, and with the complexity of semiconductor technology and market situation, the eighth generation of Core has happened very much. Great changes, including eight different products:

Kaby Lake-R 15W low power mobile version, Kaby Lake-G 65/100W mobile high performance version (integrated with AMD core display), Coffee Lake-S 35-95W desktop standard version, Coffee Lake-U 28W low power mobile version , Coffee Lake-H 35W High Performance Mobile Edition, Whiskey Lake-U 15W Low Power Mobile Edition, Amber Lake-Y 5W Ultra Low Power Mobile Edition, Cannon Lake-U 15W Low Power Mobile Edition...

It also spans the 14nm, 10nm two-generation manufacturing process, and 14nm can be divided into 14nm+ and 14nm++ versions.

This time, Intel opened up a new nine-generation Core sequence, but the manufacturing process is still 14nm++, the infrastructure is still the eighth generation of Coffee Lake, but the specification upgrade is quite large.

This also indicates thatThe division of Core Algebra will no longer depend on the process and architecture, but more on the timing and positioning of the product.

Perhaps Intel also hopes to take this opportunity to reorganize the product line, let everyone forget the complex underlying technology, pay more attention to the product itself, and the changes and improvements it brings.

Although the process and architecture have not changed, but have to admire Intel, hard to improve the nine generations of Core Duo, especially the flagship model i9-9900K, many places are the first time:

1. Introducing the i9 sequence to the mainstream desktop market for the first time

In fact, when the Core i series was more than a decade ago, everyone waited for the top products to be named i9, but Intel has been learning it. Until last year’s Core X series fever platform, Intel will have ten cores and The product on it is hung on i9.

On the previous high-performance mobile platform, the top 8 core 16 threads also used i9, andThis time Intel brought it to the mainstream desktop market, which shows the trust of these top products.

Of course, because the mainstream and fever product lines have i9, there are also i7, the model may be a bit messy, but just remember that the fever level now ends with X, the mainstream is K or no letter suffix, just fine. .

2, for the first time for the Intel mainstream consumer market to bring 8 core 16 threads

Adding more cores is Intel's main tool for the past two years, almost all product lines. The mainstream products of previous years have always been up to 4 cores and 8 threads. The 8th generation Core has come to 6 cores and 12 threads. The 9th generation has once again jumped to 8 cores and 16 threads, which can better meet the needs of multi-threading and multi-task, especially games. At the same time, you can record and broadcast live.

3, the first popularization acceleration 5GHz

The previous x86 40th Anniversary Edition i7-8086K has been able to accelerate to 5GHz, but it is a limited edition.The i9-9900K is the first time it is fully available.processorUp to 5GHz, with Turbo Boost Technology 2.0, a single core can run at 5GHz, which is a milestone.

Coupled with the high frequency and single-threaded advantages of Core Architecture, the i9-9900K is absolutely invincible in the game. According to official data, i9-9900K game performance is about 10% higher than the previous generation i7-8700K, compared with i7-6700K three years ago, up to 37%

4, the first time using brazing heat

The last time Intel processors used advanced brazing heat-dissipating materials between the core and the heat-dissipating top cover, or the second-generation Core Sandy Bridge in 2011, it has always been ordinary silicone grease, plus 22nm, 14nm process integration. The chip area is small and the heat is concentrated, which obviously affects the core temperature and overclocking.

Solder TIM can also be called solder paste. It is a liquid metal heat dissipation material with higher thermal conductivity. It can greatly enhance the heat release inside the processor and reduce the core temperature. Long-term operation on higher Turbo frequencies also helps to expand the overclocking space.

The i9-9900K, i7-9700K, and i5-9600K three new K series products use brazing heat dissipation, and they are not locked in frequency, and can be freely overclocked.

5, the first change box

Intel's processor boxes for these years are relatively simple, an ordinary square box, andThis time, a new box with a dodecahedral shape, a translucent glass material, a classic dark blue hue, and a Core i9 logo with a yellow-orange transition color, was specially prepared for the i9-9900K.

However, other models are still ordinary boxes. If you popularize this new box, it will be more handsome (of course, it will involve cost).

Specific specifications,The nine generations of Core Duo started three models, the top is of course the i9-9900K, 8 core 16 threads (also the only support for hyperthreading in the 9th generation), the third level cache 16MB (all core sharing), the reference frequency 3.6GHz, the turbo frequency acceleration Up to 5.0GHz, the official price is 488 dollars.

I7-9700KIt is also an 8-core, but only 8 threads, the third-level cache is reduced to 12MB, that is, the average per core is reduced from 2MB to 1.5MB, the frequency range is 3.6-4.9GHz, and the price is 374 dollars.

I5-9600KIt is 6 core 6 threads, 9MB for the third level cache, the frequency range is 3.7-4.6GHz, and the price is 262 dollars.

All three are integrated with the UHD 630, the memory supports dual-channel DDR4-2666, and can provide 16 PCI-E 3.0 buses (plus 40 motherboards), and the thermal design power consumption is 95W.

It is worth noting thatFor the first time, the 9th generation Core has fixed some Meltdown fuses and Spete ghost holes on the consumer processor hardware., including the fuse variant 3 malicious data cache load (Rogue Cache Data Load), L1 terminal fault (L1 Terminal Fault / L1TF), other vulnerabilities still need to be resolved by updating the BIOS and patching.

In addition to gamers, the overclocking of the 9th generation Core is also worth looking forward to, especially with brazing.

Intel live demo,Under the suppression of liquid nitrogen, i9-9900K can easily overclock to 6.6-6.8GHz of full-core, and even reach 7GHz. At this time, the running score is quite awkward, which can be equivalent to twice the frequency of i7-8700K!

When overclocking, it is recommended to use Intel's official overclocking tool Extreme Tuning Utility (XTU) to achieve more accurate frequency, voltage and other parameter adjustments to maximize the overclocking effect.

With the nine generations of Core, there areNew chipset Z390Compared to the Z370 change is not very big, mainlyNative integration supports up to six USB 3.1 Gen.2 interfacesWith a bandwidth of 10Gbps, it also supports up to ten USB 3.1 Gen.1 5Gbps and up to fourteen USB 2.0.

SimultaneouslyNative integration supports 802.11ac Wi-Fi wireless networks2x2 dual-receive dual-issue, 160MHz bandwidth, can provide gigabit wireless network, the highest rate of 1.73Gbps, also supports Bluetooth 5.0.

Fortunately, the Nine-generation Core processor package interface is still the LGA1151 remains unchanged, not only can be used with the new Z390 motherboard, but also compatible with the existing 300 series motherboards, including Z370, B360, H310, etc., the latter only need to refresh The BIOS is fine.

At the same time, Z390 motherboard can also be matched with the current eight-generation Core, which is convenient for players to choose.

Second, nine generation fever Core X: 18 core to a higher level

Intel's fever platform has always been a symbol of high-end and strength. As a top-level processor product, it is turned into a complex and rigorous work, which can effectively meet complex 3D modeling, 3D animation rendering, film and television post-production, games.DevelopmentWait for demanding tasks and applications.

Last year, the Core X series pushed into the 18 cores and 36 threads at a time, introducing the Core i9 for the first time, and all of them were named after the Core X, and they were fully open for overclocking.

This year's Core X series has not changed in terms of process and architecture. It is also a 14nm++ manufacturing process and a Skylake grid architecture. This architecture design andserverThe Xeon Xeon scalable family is the same, which is more conducive to multi-core expansion (8-28), the communication between the core is very low, and the external expansion is very flexible.

This time, the Core X series has a significant improvement in core number, cache capacity, and benchmark and core frequency. It also uses advanced brazing heat dissipation, and the price has generally been lowered to a certain extent. Full.

This year's Core X enthusiast processor has also been classified into the ninth generation sequence, the number is also 9000, which is consistent with the mainstream nine generations of Core platform, which is more conducive to users to understand the positioning relationship between the two.

Specifically,The flagship model is the Core i9-9980XE and the only Extreme Extreme Edition., 18 core 36 threads, three-level cache 24.75MB, reference frequency 3.0GHz, Turbo 2.0 acceleration frequency 4.4GHz (any single core can run at this frequency), Turbo 3.0 Max acceleration frequency 4.5GHz (automatically selected most physical The good two cores ran at this frequency), compared to the i7-7980XE, which increased by 40MHz, 200MHz, and 100MHz, respectively, and the price of $1979 remained unchanged.

i9-9960X16 core 32 threads, 22MB for third-level cache, 3.1/4.4/4.5GHz for frequency, 300/200/100MHz for the previous generation i9-7960X, and $15 for the price of $1,684.

i9-9940X14 core 28 threads, third-level cache 19.25MB, frequency 3.3/4.4/4.5GHz, 200/100/100MHz higher than the previous generation i9-7940X, the price is $1387 cheaper than $12.

i9-9920X12 core 24 threads, third-level cache is 19.25MB, which is 2.75MB more than the previous generation i9-7920X. The frequency also comes to 3.5/4.4/4.5GHz, which is 600/100/100MHz higher than the previous generation. It is the most basic frequency boost. Because this power consumption is higher, and the price is $1,189, which is $10 cheaper.

I9-9900X10 core 20 threads, third-level cache is also 19.25MB than the previous generation i9-7900X increased 5.5MB, the frequency is the same as 3.5/4.4/4.5GHz, increased by 200/100/0MHz (the highest acceleration has not changed), the price of 989 dollars is cheaper USD10.

Also note thatThe flagship model of the mainstream platform is i9-9900K, the sequence and number are the same, but the end is an X, a K.

I9-9820XThe change is very large, 10 core 20 threads, third level cache 16.5MB, frequency 3.3/4.1/4.2GHz, and the previous corresponding model i7-7820X, not only the sequence is lower one grade, but also 8 core 16 threads, third level cache 11MB At the cost of a lot of low frequency, the previous generation has 3.6/4.3/4.5GHz, and the price has risen sharply from 599 dollars to 889 dollars.

i7-9800XIs the new generation of the lowest-end model, and the only one i7, 6 core 12 thread to 8 core 16 thread, the third-level cache and the 10 core is also 16.5MB, the frequency is 3.8/4.4/4.5GHz, much higher than the i7-7800X, and Opened the Turbo 3.0 Max, and the price was $ 589, a full $ 200.

In terms of other features, four-channel DDR4-2666 memory, 24 PCI-E 3.0 channels (44 chipsets), Optanet Protoss memory and SSDs have not changed.

Particularly noteworthy are two points, one isThermal design power consumption, the previous generation Core X series has two indicators, 14 cores and higher are 165W, the following is 140W, and this generation unified to 165W, after all, the frequency has gone up, the core has also increased.

twoIt is a blown, ghost security hole. Due to the architecture problem, the 9th generation Core X series has no hardware repair, and still needs to be more detailed BIOS and patch to solve.

The 9th generation Core X series is still the LGA2066 package interface, with the chipset motherboard unchanged or the current X299, just update the BIOS.

Third, single-channel workstation: the strongest 28 core 56 thread

The 9th generation of the mainstream Core and the 9th generation of the Core X are for consumer users, and the third line of this conference is for higher-end professional users, it is the new member of the Xeon family Xeon W-3175X, Has up to 28 core 56 threads.

The Xeon W series was born at the end of August 2017, replacing the previous Xeon E5-1600 series, for the single-channel workstation field, but the product at that time was based on the LGA2066 platform, with a maximum of 14 cores and 18 threads, which is a product belonging to the previous generation Core X series fever products. People, and this time Xeon W-3175X, is the Xeon Xeon scalable server family directly from the LGA3647 platform, the progress is staggering.

Designed for large, intensive workloads, it is designed to handle some highly threaded and compute-intensive applications such as architectural and industrial design, professional content creation, and more, making it a smart choice for building enterprise servers and advanced workstations.

In fact, this product has long been seen, that is, at the Taipei Computer Show in early June this year, the CineBench running the full nuclear 5GHz speed to complete the rendering test, the 28 core that caused the audience to be amazed.

The Xeon W-3175X is also a 14nm process. The architecture is still Skylake-SP (the ghost and fuse security vulnerabilities are not hardware repaired), the L3 cache is 38.5MB, the reference frequency is 3.1GHz, and the single core turbo frequency acceleration is up to 4.3GHz, and this is the first. A Xeon with open multiplier and free overclocking.

Memory supportSix channel DDR4-2666, the maximum capacity is 512GB andSupport ECC error check, RAS featuresIt is more suitable for professional and enterprise level stable load applications.

Because the specifications are too high,Its thermal design power consumption is also up to 255W.

The package interface is different from the mainstream LGA1151, and it is different from the fever LGA2066.The LGA3647 comes from the server, so the motherboard chipset also has to be paired with the server-class C621.

The C621 motherboard currently has only two models, one is the Dominus Extreme of the ASUS player country, and the other is the SKL-SP ​​1S of Gigabyte. The design is quite exaggerated.

The former applies active fan cooling on the chipset, providing 12 DDR4 memory slots, two M.2 SSD expansion slots, and two U.2 interfaces. The latter is 28-phase power supply and four-fan heat dissipation, and seven PCI. -E x16 expansion slot.

The Xeon W-3175X will be available in December this year, but the price has not yet been announced.

As for whether this top platform will appear in the channel retail market, Intel has not yet decided.

ASUS Dominus Extreme



The three heavyweight product lines have been upgraded at the same time, and the magnitude is so strong. It can be said to be unique in the history of Intel for half a century, fully demonstrating Intel's emphasis on the PC market and its confidence in its technological leadership.

Although there have been no major changes in the process and architecture, especially the long-awaited 10nm process has to wait until next year, but Intel has completely squeezed the potential of the existing platform.

No matter the mainstream 8 core of 5GHz acceleration frequency, or the 18 core of fever, or the professional 28 core, they have reached a new height, forming a heavyweight "top legion". No matter the mainstream gamers, overclockers, content workers, you can find your favorite new platform.

Next year, it will be more exciting.
