Sapphire RX Vega 56 Ultra Platinum Limited Edition Evaluation： GTX1080

　　[PConline evaluation]Previously, we have evaluated two non-public Vega graphics cards, sapphire RX Vega 64 Ultra Platinum Limited Edition and sapphire RX Vega 56 Ultra Platinum OC Edition. As the saying goes, it takes three legs to stand out. Today, we simply evaluated the remaining non-public one of sapphire, which is sapphire RX Vega 56 Ultra Platinum Limited Edition. Let’s take a look at the difference between "limited" and "unlimited" graphics cards.

　　The product packaging still has the traditional robot of sapphire, which is a set of commercial modeling products specially designed by designer Mohammad Hossein Attaran. In order to facilitate identification, the angle of the outer packaging robot is different.

　　The appearance of the graphics card is the same as that of the sapphire RX Vega 64 ultra-platinum limited edition. The overall background of the graphics card is pure black, and the material is skin-like material inherited from RX400 ultra-platinum series, which will be more comfortable to touch in winter. There are lights around the fans on both sides of the graphics card, and there are acrylic backlit lampshades on it. The overall look and feel is very much to my liking, but the aesthetic view is different, so you can judge for yourself.

　　The product is used.Tri-X three-fan cooling systemOne fan is 9cm, and the others are 10cm. The fan adopts double ball bearings, which has high durability and isQuick release designOnly one screw is needed to remove it, which is convenient for players to carry out dust removal maintenance and fault replacement. In addition, the fan also has intelligent start-stop technology, which can only be started when the temperature of the graphics card is higher than 60, which greatly reduces the noise and power consumption of the product under low load.

　　The graphics card size is 310*133*54mm, and the product is relatively large and heavy.For 2.5 slot cards.

　　The graphics card believes in the light, which is a mirror when it is not on, and shows the sapphire LOGO when it is on. The details will be reflected in the lighting test.

　　In order to ensure the stable power supply of the graphics card,The external power supply interface is3x8PinThis also means that the performance contrast of the graphics card is stronger, but it also leads to the poor adaptability of the sapphire RX Vega 56 ultra-platinum limited edition. After all, not all power supplies have so many 8-8Pin interfaces, so consumers who want to buy it should pay attention.

　　The graphics card is equipped with an all-metal backplane to help the graphics card dissipate heat.The back plate is always ultra-platinum style, and there will be an ultra-platinum exclusive LOGO on it.LOGO is made of transparent resin, which will reveal light when the machine is turned on..

　　The output interface has two DP1.4 interfaces and two HDMI2.0 interfaces, which is more friendly to VR games.

　　Turbo-X system is a special cooling system of this sapphire RX Vega 56 Ultra Platinum Limited Edition, which can control two additional PWM fans located in the chassis through the interface on the graphics card. An independent controller can intelligently control the speed of the fan connected to the graphics card according to the five temperature sensors on the PCB, so as to improve the overall airflow of the system and play an auxiliary heat dissipation role.

　　Considering that the graphics card is relatively heavy, sapphire will send a sapphire belief graphics card bracket with the card, which is very intimate.

　　Compared with the sapphire RX Vgea 56 ultra-platinum OC version evaluated before, the biggest difference in the appearance of the graphics card is that the background color around the fans on both sides is black with lighting effect, while RX Vgea 56 ultra-platinum OC is silver-gray without lighting effect. In addition, there will be one less external power supply port of RX Vgea 56 Ultra Platinum OC, which is 2x8pin.

　　Then we began to disassemble it to see how the materials used in the graphics card were.

　　The same heat dissipation design as other Vega series non-public graphics cards of sapphire,The graphics card radiator has two layers, the lower layer is the cooling module of the power supply module, and two auxiliary 6mm heat pipes are specially used for cooling the power supply module. This design greatly reduces the temperature pressure of the power supply module. reviewThe PCB version of the graphics card, we can see that the graphics card adopts14+1 phase full digital power supply, which is consistent with RX Vega 64 ultra-platinum limited edition and two phases more than RX Vega 56 ultra-platinum OC. The core power supply MOS is one up and one down, and the bridge is connected.The MOS is IR6811 and the lower bridge MOS is IR6894.,The inductor uses sapphire.Fourth Generation Black Diamond InductorIt has higher electromagnetic conversion efficiency, and the inductor has a heat sink built in the coil, which reduces the temperature by 10% compared with the third generation while running more stably, and can effectively suppress the problem of high-frequency howling. Capacitors are used.16K all-solid-state black gold capacitorThe service life can reach 16,000 hours. The whole PCB adopts the shoulder-jumping design, which provides more space for the graphics card to increase the heat dissipation scale..

　　It can be seen that the heat dissipation module isPure copper base, the same as sapphire RX Vega 64 ultra-platinum limited edition, but RX Vega 56 ultra-platinum OC is just an ordinary base. It seems that this is the treatment only for ultra-platinum limited series graphics cards.

　　Vega core and Samsung HBM2 memory, memory single 4G, a total of two, 2048 bit memory bandwidth, equivalent memory frequency of 1600MHz.

　　The upper radiator uses the causeChamber vacuum cavity vapor chamber heat dissipation technology, which is famous for Vapor-X series graphics cards, sapphire official test shows that under the same conditions, using vapor chamber directly on GPU and HBM2 can reduce the temperature by 5 C compared with pure copper base (for example, RX Vega 56 ultra-platinum OC is pure copper base).,This is also the treatment of ultra-platinum limited edition series graphics cards.In addition, the radiator is equipped with 6 nickel-plated heat pipes of 3*6mm and 3*8mm, plus two auxiliary heat pipes of the power supply module at the bottom. The sapphire RX Vega 56 ultra-platinum limited edition radiator is actually equipped with amazing.8 heat pipesThe heat dissipation specification is very luxurious.

　　Sapphire RX Vega 56 ultra-platinum limited edition is also designed with dual BIOS, and the specific parameters are as above. For the convenience of comparison, we listed the parameters of public edition and RX Vega ultra-platinum OC. Compared with RX Vega 56 ultra-platinum OC, the gear frequency of RX Vega 56 ultra-platinum limited edition OC is more radical.

　　Description of test platform:The test platform is the mainstream consumer platform Z270+i7 7700K. In order to facilitate consumers to compare products, we added the achievement of sapphire RX Vega 56 ultra-platinum OC. In this test, six graphics cards were selected for comparative test, mainly 3DMark and mainstream DX11/DX12 games. examConsidering the length of the chart, the following test chart indicates that the sapphire RX Vega 56 ultra-platinum OC is RX Vega 56 ultra-platinum and the sapphire RX Vega 56 ultra-platinum limited edition is called RX Vega 56 ultra-platinum limited edition.

　　In the theoretical test part of 3DMark, in addition to the commonly used FireStrike and FireStrike Ultra tests, the DirectX 12 benchmark test Time Spy newly launched by 3DMark is added, so as to bring you a more comprehensive reference.

　　Summary of theoretical test:Due to the temperature and power consumption, the actual operating frequency of RX Vega series graphics cards depends largely on the heat dissipation of BIOS and graphics cards, and often does not reach the highest frequency. Therefore, it is difficult to measure the performance by looking at the product frequency, but we can get an accurate answer through 3DMark theoretical test. In the testThe scores of sapphire RX Vega 56 ultra-platinum limited edition OC file are improved compared with the public version.11%The increase is amazing.FireStrike and FireStrike Ultra have even surpassed the GTX1080 public version. In the energy-saving gear, the graphics card has also improved compared with the public version.1~3%It should be that the frequency is more stable. Comparison under OC gear of graphics cardSapphire RX Vega 56 ultra-platinum OC has also improved its performance under the OC file.3~8%The difference is obvious.

　　In this test, we have selected five representative game masterpieces, including Tomb Raider 10, popular games "Survival of the Jedi" and "Whole Territory Blockade", which are native to DX12.

　　Game test summary:It can be seen that the performance improvement range of sapphire RX Vega 56 ultra-platinum limited edition game is basically the same as that of 3DMark theoretical test score, and many games canDraw GTX1080 public edition,Direct pursuit air-cooled version RX Vega 64 .

　　Test summaryWe conducted 3DMark stress test on the graphics card in two gears respectively, and only 97% of the test passed, while the sapphire RX Vega 56 Ultra Platinum Limited passed in two gears with high scores of 99.6% and 99.5% respectively, indicating that its stability is absolutely no problem. In addition, we can see that the highest running frequency of the graphics card is 1399MHz in the energy-saving gear and 1548Mhz in the OC gear, and the actual running frequency difference between the two gears is close to 150MHz.

　　Sapphire is also very powerful for controlling the temperature of the graphics card. After all, 8 heat pipes andChamber vacuum chamber vapor chamber is not fake,Both gears are pressed below 60, 59 and 55 respectively. In contrast, the temperature of both gears of RX Vega 56 Ultra Platinum OC is 55, after all, the frequency is much lower.

　　Summary of power consumption test:Among so many A-cards, the public RX Vega 56 is the graphics card with the highest energy consumption ratio, and the power consumption and performance of the sapphire RX Vega 56 ultra-platinum limited edition energy-saving file are also very balanced. From the above, we will know that the performance of the product energy-saving file will be slightly stronger than that of RX Vega 56 ultra-platinum OC energy-saving file, but the power consumption is basically the same. It is speculated that the GPU of the ultra-platinum limited edition graphics card is the special core, which can be used lower to achieve the same frequency. In contrast, due to the 14nm process limitation of GF adopted by Vega core like Ryzen, the power consumption suddenly rises after exceeding a certain frequency dessert, and the power consumption of sapphire RX Vega 56 ultra-platinum limited edition oc file will also be relatively large.

　　Summary of noise test:Product noiseCompared with the public version, it dropped significantly and performed well in the noise test.

About noise:

　　0-20 decibels: very quiet, almost imperceptible; 20-40 decibels: quiet, like whispering; 40-60 decibels: general indoor conversation; 60-70 decibels: noisy: harmful to nerves; 70-90 dB: It is noisy and nerve cells are destroyed. 90-100 decibels: increased noise and hearing loss; 100-120 decibels: unbearable, temporarily deaf after staying for one minute. Above 120 decibels: extremely deaf or totally deaf; About 300 dB or above: 20km of people in Fiona Fang are irreparably deaf.

　　Sapphire RX Vega 56 Ultra Platinum Limited Edition lamp is RGB. We can download special lighting control software from Sapphire official website to control and manage the lighting, which can adjust the brightness, color, breathing mode, etc. There are many functions, so I won’t list them one by one here. Feel for yourself.

　　Ladder diagram descriptionBased on the above test results, the position of sapphire RX VEGA 56 ultra-platinum limited edition graphics card on the ladder diagram is as shown above, which is slightly lower than the GTX1080 public version.

　　Through this evaluation and comparison, we should know and understand all aspects of sapphire ultra-platinum twin. Sapphire RX Vega 56 ultra-platinum limited edition undoubtedly has stronger performance, better materials, and the core should be specially selected. Of course, the price should also be higher. As for which one to choose, it is up to you to measure. In the last article, I also said that in the case that the GTX1080 of N card has also risen to more than 5,000, and the GTX1080Ti is generally more than 7,500, the RX Vega series graphics cards are no longer low in cost performance. If you like it, grab it and take it away. After all, this graphics card is limited.
