In the previous article, I was passionate and passionate about unpacking ASUS's ROG STRIX-X299E-GAMING, saying that I had to wait until July 8th to get the 7820X. I would like to share with you this generation of the Core Extreme series, but... ...the following things happened within two days...
PS This time because of the test time is tight, so the entire mobile phone camera, please bear with me.
In the most recent period, Changsha was overcast and rainy. In the morning, I had no lunch at lunch and I was anxious to go to the computer city to help others buy something. No traffic jams along the way... 
When JD was not popular before, I was often pulled by colleagues and friends to Computer City to help with the selection of accessories, notebooks, and so on. In fact, I was not very 6 at that time, but it looked like it was 6, and several times she had been pitted. However, the computer city is not all profiteers, according to my experience, looking at the very warm and handsome guys hanging out at the entrance of their own storefront or elevator business loitering, generally not very authentic, but looking at the inside of the shop no one, the boss It's more reliable to type in the shop. I had the privilege of inadvertently knowing such a few businesses, these businesses generally look at you into the store and say a few words on their own to their own, and you see, ask before answering, ask more do not buy it does not matter, the next time is still the same, Will not be impatient, and later cooked up with these people to know that ... ... people to engage in a facade is just a facade, not at all bad, "sort of" these few money, Taobao are too lazy to open, "old with new" is enough for them to work , Please note that here the "old with the new" refers to the big customers, such as Internet cafes ... ... the company ... ... organs to buy what ... ...
When it was time to go out, it was still not raining. When it arrived at Computer City, it was a little rainy. The computer city in Changsha was generally concentrated near the train station. The parking fee was expensive, but you could stop for a few hours for free.
Well, I got a little bit far and continued to talk about business... After I bought something, I was thirsty. So I thought of a standing beverage company where I sat for a while. It was also a friend. Sometimes I don’t know anything about computers. Will also ask him, when drinking Sprite and talking to him, he suddenly thought to ask him if he had a 7820X flake to buy, when I asked for an exit, he stumbled, saying that you are not another 1700X yet, but also to buy 7820x Why, then I told the original party 1510, he thought to me and said to me: "7820X is not a piece, but I have a 7900X in my hand, I used it myself, you see what you want Don't..."
Intel Core 8 core i7-7820X boxed CPU processor 4410 yuan Jingdong to buy I said, "Too expensive, don't." So he thought for a moment, and meaningfully slowly took out a toilet paper from the drawer. "Or else, I don't charge you a deposit. You take it for a day, tomorrow." I'll come back and I'd like to buy it again.†Then... I’m full of promise... Then I go downstairs hurriedly, this time it’s almost 5 pm...
To be honest, I'm not going to buy the 7900x at all. Even if I try to be cool, I'll only buy the 7820X. Because the 7900X is priced at 7,000, it's too expensive. I can buy a set of 1800X and a set of 7700K. It is really a luxury, a local tyrant’s toy... considering that we have to wait for JD’s goods, so I’m just not on the chassis...
1, Intel Core i9 7900x 10c20t
Intel Core ten core i9-7900X boxed CPU processor 7410 yuan Jingdong to buy I9 7900x is using a new 2066 interface, only the x299 chipset motherboard can support this thing has nothing to say, larger than the general i7, thermal cover is basically full coverage. Pictured
The substrate is thicker and thinner than the Ruilong, and it is the same as the 7th generation i7, but it does not matter whether it is thick or thin. It does not affect performance.
Backside
Not ready to open the lid, so the CPU has nothing to show, probably it is this kind of specific performance to be reflected in the back of the test. OK, then let's show you some of the hardware that was played with the 7900X this time.
Kyushu Captain Fengsong 240 upgrade RGB version of the CPU water-cooled radiator (breath lighting effect / support for multi-platform) 889 yuan Jingdong to buy Why buy it? Because the water-cooled + RGB, but also from the cold head does not look vertical LOGO ... This is the reason ... out of the box feel good work, after the machine is used, I found this radiator is not in the fan when the turn is very Silent, water pump and fan are all, the noise is bigger after the fan starts to rotate. The specific number is not seen. Personally feel that there should be about 2000 rpm, and the sound is slightly louder than that of the fan used before. A bit, but that fan speed is not very high, the fan connector I was directly inserted on the motherboard, and did not use the bundled hub, I do not know if this is the reason. Thermal performance, because there is no time to make comparisons, so it is not easy to say, anyway, the default frequency of 7900X is still enough.
ASUS ROG STRIX-GTX1080TI-O11G-GAMING 1569-1708MHz 11G/11100MHz GDDR5X PCI-E3.0 graphics card 6399 yuan Jingdong to buy During the period of this card shortage, the brand-new card is very difficult to buy, the one that can buy a little is basically above 4,000 above 1000, because I changed the monitor of 165Hz, so the previous 1070 is already not enough, scouring a GTX1080TI ......The performance is not tested, anyway, 2K large game wants to run at 165 FPS, it is still difficult, and special effects should be appropriate......
G.SKILL Series DDR4 3200 Frequency 16G (8Gx2) Set Desktop Memory RGB Light Bar (F4-3200C16D-16GTZR) Trident Z is the flagship series of Zhiqi, positioning higher than Ripjaws, Trident Z RGB It is a lighted memory bar product introduced in 2017. This Trident Z RGB 16GB kit contains two 8GB, 288-Pin desktop specifications. DDR4 3200MHz frequency, support Intel's XMP 2.0 technology, a key value 16 Comments0 Original 2 Good price 5 To buy see details This memory should be one of the better models to be sold in the high-end market this year. It matches the ASUS AURA SYNC system very well. Can not buy this price now, before I bought Jingdong 1199. In fact, at the beginning, I bought 4 of 3,000 for 999 and then gave it to my friends to buy this one. Very unfortunately, buying one of the two sets of one is bad... This is the third time we have encountered this situation. Chi Chih QC is open to question, but the JD service is also worry-free. How to say it, the pursuit of simple cost-effective is not recommended to buy, but the pursuit of personality, I think it is well-designed.
Intel (Intel) 600P Series 512G M.2 2280 Interface Solid State Drive 1449 yuan Jingdong to buy The NVME solid state at a very general speed, at the time of the price and 5 year warranty, the quality of the INTEL SSD warranty service is one of the best, so if you have enough money, buy a good one. In fact, I also was the game board, the system disk is Jianxing T10, but also a cost-effective embryo, but the Jianxing T10 temperature is a bit high, mindful friends can ignore. As for the speed, in fact, I don't use the difference between SATA and NVME under normal circumstances...
US Corsair rated 850W RM850i ​​power supply (80PLUS Gold/C-Link/Low-load fan stall/10 year warranty) CORSAIR (Viking Ship) RMi series power supply, is the top version of RM series, all components use Japanese capacitors , More stable and longer life, After-sales warranty period increased from 5 years to 10 years, while still has 80PLUS GOLD gold certification, 135mm fan and zero-speed silent mode, full module joints, and supports ship-top C-Link technology ,Can check, monitor power supply through software processing, and perform some values ​​2 Reviews 0 Original 0 Good price 3 to buy View Details Before the special offer to grab ... I thought 850W enough for me to play ... ... when I met this 7900x ... ... forget wait and see. This power is relatively long, do not buy the chassis space cramped. I also fancy its monitoring function, you can see the power consumption, current and voltage of the power supply in real time, and it is very convenient for those who like to do evaluation.
There are so many accessories introduced, the protagonists of this time are 7900x and X299E... It's almost mixed up...
OK, first on the family (except for the power...)
I9 7900x is ready to go on the machine, in order to protect friends from being investigated by the meter, so the serial number is hidden...
Then on the cooling, find four screw posts, two beams, and four fixed screws. The "Captain" parts work well, like a few. ↓
Install four screw posts. ↓
Put on Liang Yi
Tighten 4 setscrews
Get ready for the cold head
Secure the screws after aligning them.
This is all the joints of one fan and one water cooler...
This is the head of the RBG control line
RGB control money under the bayonet, direct card owners can. ↓
Two fans have an RGB4PIN connected to the motherboard. ↓
X299E has a separate pump control interface, the water head power supply is connected, the captain pump can not speed, so the significance of the special port, if the PWM function of the water pump can be adjusted through this interface speed ↓
Spider web thread
Overall, the captain's cold head is still pretty, there is no LOGO, it is very pure.
Connect the module cable
The previous one shows the steps of installing the SSD under the heatsink under the motherboard. Here you can see how to install a vertical SSD.
Mounting limit bayonet
Then insert the SSD into the interface. Of course, the first mounting bracket can also be used.
Then place the bracket and prepare the screws.
Completed installation
Fixed limit buckle, have to say that this installation method is still very curious in my eyes, but now many motherboards have chosen to install this way to save board space. ↓
Install memory
Installation of memory is very simple, they are installed in a slot, A1 B1 C1 D1
On the graphics card
This 1080Ti and 1080 with the same paragraph without crying
It is worth noting here that some people installed SSDs in the morning group because the screws were too tight and the pads below were too thick, and the SSD was pressed out of the way.
The antenna is installed
Nuclear missile ready↓
After the power is turned on, the RGB LED on the motherboard will light up. Asus's lights do a good job and there is no such cheap feeling.
A fusion strike on the way was detected...
OK, I spent a time hanging on the system and had a meal. Poor me ... I can only eat instant noodles.
After the meal came back to see, Xu Tong installed, WIFI drive automatically there, it is convenient, it seems X299E this motherboard's wireless network card is free drive.
OK, finished.
Enter the performance test
First introduce the platform and test items.
Through the CPU we can see that this 7900X is already the official version of Stepper 4
Motherboard information
Memory information
Master Lu computer profile, detection is no problem ↓
Taking into account the length of space, I will not dry out the performance test results one by one, a summary shows to you, I will do analysis. For the sake of time, I did not do in-depth overclocking tests with memory frequency and channel tests. The data ran in two groups. One group defaulted. One set of OC to 4.5 GHz (automatic voltage) was run again and compared. The memory is shown in the figure above. All of the frequencies are 3200. The timing is 16-18-18-38 1T. (XMP)
The data on the PS phone may not be clear, the computer can see clearly, if you do not see the phone, you can directly look at my analysis below.
Overall, the performance of the 7900X should be the strongest among desktop PC CPUs that you can buy (and will soon be able to buy). After all, 10 cores and 20 threads (from the point of view of CR15) are not overclocked. It is about 25% stronger than Ruilong's strongest 1800x overclocked to 4.0GHz, but ... the price is 1.875 times that of the 1800x starting price. If it is bulk, it may be a little cheaper, but a better 1700X can also Stable overclocked to 4.0Ghz, the performance is equivalent to the 1800x 4.0Ghz performance. The current price of the 1700x is about 2400, so the price of the boxed 7900x is more than three times the price of the 1700x box.
If you think that Ruilong overclocking is unfair to the 7900X frequency, then compare my 1700x frequency of CR15 to compare
Single-core performance 7900x over 1700x about 30%, multi-core ultra 42%, the price than just said, more than three times ... ...
But then again, if the performance or demand of 1800x and 1700x is not enough, then it's a waste of money. Of course, the performance and requirements mentioned here also include installing X...
However, if it is playing games, 7900x does not have any advantage, such as the same conditions test "World of Warcraft", 7900x OC to 4.5Ghz with 1080TI frame rate between 25-186fps, an average of 72.151, and 7700K + RX480 is 49-136, average 92.319, 1700X OC 4.0GHZ + RX480 frame rate between 28-138, the average frame rate is 67.589. This shows that the old games like "World of Warcraft", the CPU severely limits the performance of 1080TI performance. In addition to the "World of Warcraft", I also tested the "watch pioneer" 7900X, from the test data point of view, the super-overclocking does not affect the "watch pioneer", the previous test can also reflect this phenomenon, that watch the pioneer Reliance on single-core is not high, or multi-core optimization is good. Therefore, we can conclude that if the 7900X was chosen to play the game, it is obviously not the best choice.
OK, then return to 7900X performance itself, why choose OC to 4.5GHz this frequency? This is because 4.5GHZ is the highest frequency (single core) that the 7900X is able to reach. At OC to 4.5GHz, performance and speed increase are mostly between 12-25%, basically meeting the frequency increase.
but! ! ! ! ! ! (The focus of this test comes)
When the 7900X was overclocked to 4.5GHz, the AIDA64 stability test single FPU roasting machine temperature was raised from 65°C to 105°C! ! ! 60% increase! ! ! The power consumption of the whole machine is increased from about 230W to about 450W! ! ! Increase 95%! ! ! So can you understand the meaning of my title? ! ! ! This is a nuclear bomb! ! ! (ps I repeatedly test several times, and even restart and test again, still so, I would rather hope that this is a software or hardware bug, or if you think it may be something to welcome.)
The above picture may not be clear, because the temperature reached 105 degrees Celsius, so I did not continue the roasting machine, afraid to burn the CPU, not accountable to a friend, the CPU voltage I set automatically, whether AIDA64 or CPUZ detected The CPU voltage is stable at 1.281v.
Master Lu’s stability test was slightly more normal, with temperatures rising from 58 to 73 and power from 317 to 376. After facing the AIDA64 earth-shattering data, it was wrong to look at this group of data...
What is the temperature and power consumption of the 7900X standby? The default frequency standby temperature is about 30 degrees Celsius or so, 4.5 GHz standby temperature fluctuates roughly between 35 to 40 degrees Celsius, and the silent standby power consumption is roughly 75 W. The 4.5 Ghz standby power consumption is about 85 W. These are fairly normal, and from On the books side, the 7900X temperature control is pretty good at the default frequency. And this 7900X experience basically did not encounter any compatibility issues, memory properly and everything properly, online motherboard power supply temperature is too high not met (hot or hot).
After this test, it was already 3 am, it was sleepy and tired, and it was half-hearted. The grass of the 7820x tree was therefore pulled out completely. After a night of tumulting and deliberation, I seemed to be able to Irresponsible anticipation of AMD's "thread-breaker" after the market, KabylakeX processor's possible price diving ... I think ... KabylakeX is not suitable for me ... this mouse I improper ... not to mention KabylakeX platform in addition to pretend X It doesn't give me a real advantage in performance. Moreover, I never installed X.... I slowly thought of deeper and deeper... I began to regret my 1700X, C6H, RX480, RX580... I even thought it was for me. Before the 7700K is more practical than him...
The next day, after returning to the 7900X after a heavy rain, he returned to the motherboard with a good deal of money after he returned to negotiate with the seller. But don't take it out of context. I'm quite sure that the 7900X is absolutely in terms of data processing performance. Advantages, but cost-effective and overclocking power is really difficult for ordinary players to accept, I believe that for enthusiasts, 7900X is still the absolute choice of desktop PC CPU at this stage.
Finally talk about happyIn fact, KabylakeX began to measure online some media is called bad, I simply do not believe evil toss, fortunately many friends ... ... please drive, avoid a "drunk drive" accident ... ... although some compromise but also Better than bleeding ... but this toss has an unexpected harvest ... ASUS SYNC system with a variety of RGB accessories, the effect can really feel that all major manufacturers nowadays all kinds of accessories next to this road RGB can still go , high-end market, low-end market solutions will be far behind? Then it will spell quality.
The above picture is the ASUS AURA SYNC software interface, a lot of light effects are always suitable for ... If it is ASUS's mouse, keyboard, then the same linkage, the effect is good. In fact, AURA SYNC has already been introduced in the previous Z270F article, interested friends can go and see, here will not do too much to go into details, this shows a few motion pictures to tell the officials to end this sharing.
Thank you for watching and welcome the exchange.
