IT168 evaluation crossfire refers to the dual graphics crossfire, the use of AMD dual graphics crossfire technology, we can make the platform's game performance instantly improve, and the cost is often not to buy a new card, especially for the budget is not much game users. Of course, dual card parallel connection is actually not only AMD's crossfire technology, there are NVIDIA's SLI; from the market side, A card's high memory bandwidth in the 1080P/4K resolution under the crossfire performance advantage is obvious, especially the R9 level R9 The 380 advantage is more obvious, so many users switch to AMD's. The core code of R9 380 is Antigua, which is renamed Tonga Core of R9 285. It belongs to GCN 1.2 architecture and has 1792 stream processors, 112 texture units and 32 raster units. Currently, the R9 380 graphics card with 4GB 256-bit GDDR5 memory is only about 1,500 yuan, and the price/performance ratio is quite high. Here, we used radium wind R9-380 Ustorm-4GD5 as our crossfire test! Before setting up a crossfire platform, you need to know whether your motherboard supports crossfire. Generally, we can see CORSS FIRE in the box on the motherboard, or you can see whether the motherboard supports dual card exchange on the motherboard manufacturer's official website. (At present, most motherboards support dual card exchanges). Followed by the power video card power supply capacity & number of interfaces, for the thousand-level graphics card, dual card crossfire needs to use four 6Pin video card power supply interface, while the power supply capability +12V is the best single 40A or dual 20A! The test method is actually very simple, we use the 3DMARK series to test the theoretical performance, and we use two different DX11 games to test the game performance. The game test part is dust 3, and the game with BENCHMARK test can be quickly and automatically tested; while another game is Sorcerer 3: mad hunting, which needs to be tested with FRAPS. From the perspective of the 3DMARK theoretical performance, the performance improvement of the radium wind R9-380 Ustorm-4GD5 dual-card crossfire is quite large, basically with a performance improvement of over 70%. At the same time, we also found that after the radium wind R9-380 Ustorm-4GD5 dual card crossfire, obviously felt that the system bottleneck is from the CPU, even if the 4770K overclocked to 4.0GHz. Sorcerer 3 is a relatively popular large-scale game recently. It has a higher requirement for the graphics card. It only uses a Rafonic R9-380 Ustorm-4GD5 graphics card with 35 FPS frames, which can only meet the basic needs when the battle scene is more complex. Slight performance. However, after using two radium winds R9-380 Ustorm-4GD5 dual card crossfire, the FPS value reached 57, quite smooth, no longer afraid of the card machine. Similarly, only dust 3 is the first generation of DX11 games, the demand for the current graphics card is not high, the single card FPS value is 110, and the FPS value is 166 when the dual card crossfire, this improvement is really quite obvious . The next side is our power consumption problem. For a 1K5 graphics card, the power consumption of the 236.34W when the game is fully loaded is very gratifying, and the standby power consumption is only 51.28W; at the same time, even a dual card is not necessarily high power consumption, dual card standby power consumption is 63.97W , dual card game full load 392.46W. From this point of view, as long as it is currently more than 500W gold medal power can be loaded with the need for dual-card crossfire. In fact, it is not uncommon for two cards to be purchased together to make an exchange of fire. Only users who have A card dead powder or who have excessive pursuit of the game will consider it. Conversely, the purchase of video cards to upgrade to achieve crossfire, R9 380 is R9 285, before the price is higher but quite recently used. Before the price of 2K, now only need 1K5 can win, and is 4GB version Oh, after the exchange of fire performance improvement is quite obvious, power consumption is not high, quite value. Both the positive and negative sides of the video card are accompanied by the iconic red circle. This is one of the largest symbolic LOGOs of the radium wind Ustorm series. Silver and black with a classic and stylish, while the three-fan design, so that the appearance is even more domineering. The back is a metal backplane, which is rarely seen in the thousand-level graphics card. The output interface is also rich, with two DVI, one HDMI, and one DP interface. The DVI TO VGA converter is also included in the accessories, which can meet the needs of different users. The highlight of radium wind Ustorm is the beginning of the BIOS switch, the high and low frequency BIOS switch through the backplane switch. Enhanced E-AIR smart cooling system, radium wind home launched three fan five heat pipe radiator. The heat sink base part is treated with aluminum inlaid copper. The GPU contact part is hollowed out as a pure copper bottom, and the periphery is made of aluminum metal. However, it is not known why, for the memory cooling location, the aluminum protrudes but no thermal pad is added. This does not help the auxiliary memory cooling. Heat sink body adopts FIN type heat pipe + reflow soldering, and the number of heat sinks is quite large. However, with the 2.5-slot graphics card design, the heat sink thickness is a little inadequate. As for the reflow soldering, for the perfect idea, there are some heat pipes in the reflow soldering process that are not soldered. Although they can still dissipate heat, the heat-dissipating effect seems to be not optimal. The design of two 8cm and 9cm fans is better than the design of dual fans, and the same spoiler problem is also solved. Three are fans with PWM intelligent speed control, which can control the fan speed according to the load conditions. At the same time, this time Ustorm also brought RGB load LOGO light, so that the memory load condition can be seen in real time, and it can also play the role of 13 installed. Furmark test is much higher than the load when the general game is loaded. Selecting 10 minutes of test time can quickly and effectively test the cooling effect of the video card. Radium Wind R9-380 Ustorm-4GD5 standby temperature of 38 degrees, full load temperature of 67 degrees. Just now I was a bit dissatisfied with the graphics card cooling, but looking at the full-load performance here is really good, for a thousand yuan memory is already quite good. PCB The Chinese people think that the bigger the PCB, the better the graphics card! Of course, this sentence is useless on Fury X. The PCB is not as big as possible. Reasonable layout and luxurious materials are kings. From the radium wind R9-380 Ustorm-4GD5 graphics PCB view, the front of the core power supply, the rear of the memory power supply allows the PCB length is quite long, but the layout design is fairly reasonable, the material is also good. The Antigua core does not have much to say about it. In any case, it is the latest GCN 1.2 architecture with a lot of performance improvements. As for the video memory, Samsung's 4Gb HC03 particles are used, and the front 8 pixels form a 4G/256Bit memory specification. If you do 2G version of video memory, then you only need to replace the particles with 2Gb. The core power supply section is doing quite well. The eight-phase design meets the current demand of the memory core at high frequencies, and the core power supply has better pre-electrical performance. The use of materials used part of the United States and the United States NCP5369 DrMos, this MOS tube is mostly used in high-end graphics card, which has excellent electrical performance, while lower heat, so the MOS part does not need to strengthen the heat sink. stainless steel phone cases for sale,custom stainless steel cell phone case,stainless steel cell phone case bulk,safest phone cases Dongguan Yingxin Technology Co., Ltd. , https://www.yxsparepart.com
