Farm AMD Polaris RX480 has been listed for more than a month. The version just listed is almost the same as everyone. All of them are public versions, and you can buy them almost completely at liberty. However, after all, the public version is not used to take volume, so after the mass market sale is certainly a non-public version of various manufacturers.
I started off with a public version of my own before it was tested. Originally also considering whether to buy 2P to do CF, but still want to say that when a non-public version of the time just just under the contrast; just before they participated in the Aunt's GTX1080 public testing, but also in order to compare the performance of RX480CF, so just the first release of RX480 We booked 1P at the time.
The reservation is the sapphire ultra-white OC version, many players are also concerned about, this version is currently the highest frequency in the market RX480 version, so after the release of overseas news, there are actually many players in the actual domestic version of this version of the on-line.
The packaging should have nothing to introduce, and it is still in the previous style. The card itself is covered by a film. The students who buy the card can pay attention to it and identify whether the card is used. 
The appearance of the graphics card is still a very direct and violent dual fan + backplane performance orientation setting. However, the overall heat dissipation scheme of Ultra Platinum is quite exaggerated. The fan is 9.5cm in size, and its height is much higher than that of the public version. The entire radiator cover is almost a whole brick, it is a very violent brick. 
The most favorite is the painting of the backboard, but the painting of the front panel is different from the back, which is a pity. Obviously positive, too low-keyed. 
The IO port is somewhat different from the public version setting. It is a 2HDMI+2DP+DVI setting. The added HDMI is for the convenience of an external VR device. 
Because it is an overclocked version, the power supply port has also been changed to 8pin. 
A key detonated. . . The actual side is two buttons. The red fretting is the mode of switching the above belief light. Next to another switch, two groups of BIOS can be switched. One group is the public version frequency, and the other group is the overclocking frequency. 
There is an opening in the back panel, see the design instructions for a certain degree of drainage 
RGB belief lamp, RGB also burned to the PC accessories above, the motherboard graphics can not escape. 
In terms of heat sinks, the fans were designed to clean up dust and maintenance. This type of single-screw module was used to set the fan. However, the fan does not seem to have seen retail yet. 9.5cm fan, using a ball fan. 
Dismantling time
The dismantling difficulty is moderate, and the whole video card is composed of a video card body, a backplane, a heat sink and an air guide cover. 
The design of the backboard is mainly the air flow. In addition, the graphics card itself has a heat-conducting plastic link, which can help the power supply part to assist in heat dissipation. 
Heat sink, visual inspection is a combination of 8mmX2+6mm, copper bottom, wear fin process; heat pipe surface is nickel-plated. 
Both memory and power supply are thermally conductive. 
Wind hood, mainly used to fix the fan. 
Graphics card PCB body, layout, workmanship with materials should be clear at a glance. 
The lamp of faith said earlier.

GPUZ identification, different BIOS frequency settings, overclocking set the core to reach 1343hz, the highest commercially available version. 
Theoretical testing
Still mainly with 3DMARK and SteamVR, 3DMARK normal mode will not run, the market card break W test no meaning. In addition to the theoretical performance of the public version of the frequency, can be considered reference to the theoretical test after the increase in overclocking.
3DMARK, overclocking has been improved, the increase can refer to the picture. 
DX12 test, mainly TimeSpy (because the version is not purchased separately, there is no switch asynchronous budget), and the word table data column ratio can also be ignored, the actual gap is not as large as the table, but the performance improvement after overclocking is still a little bit. 
SteamVR: Average fidelity index after overclocking also reached 6.9, while the public version is generally around 6.4, it seems quite sensitive to the frequency. (Similarly, if you look at the values, you can ignore the proportion of histograms) 
Game testing
After running several mainstream games and recording the number of frames and the average number of frames, I believe it can also be compared objectively.
In addition, the main test resolution resolution 1440p, without it, personally feel that the current 2K + level graphics card, it should be to ensure that the 1440P can play. Of course, in addition to GTA5, because this game is really eating too much resources. 1080P, really no test necessary, all kinds of fully open (also in addition to GTA5)
Watch Pioneer: All are Qijiang tower team battle, test the 1440p with 1080p, in addition to the curve of the RX470, ultra-platinum in the 1440P full open frame number reached 67, more than smooth standards, can basically guarantee watch pioneer all maps 1440P In the case of 60P, the public version is not overclocked at about 2.3 frames, while the RX470 is just 60. 
GTA5: 1080P case full effect, about 48p, so this level of card, or just suitable for 1080P playing GTA5. However, it is very strange that the decline in the number of 1440p frames is not exaggerated, but also 30P level.
Dota2:1440p test, special effects open casually. 
Dark Souls, Call of Duty - Black Action #3: The two are somewhat similar in terms of eating resources, and Ultra Platinum can basically guarantee 1440p in smooth situations. Of course, if you want the whole scene to be smooth, there may be special effects in some places. Optimize, such as AA/AF these anti-aliasing options. 
Power consumption and temperature
Because A, N will be for the furmark like test software to limit power consumption, so the power consumption are all tested in the actual game, rx480 ultra-platinum game, the power consumption is about 250w, because it is overclocking so also It will be higher than the default frequency of the public version. The public version of RX480 and 1060 public version of the game power consumption is about 220-230. 
At temperatures up to about 74, the fan speed does not exceed 2K, and the noise is moderate. 
Final summary
Sapphire RX480 8G D5 Ultra Platinum OC version, the current design of the entire card is relatively balanced, and the actual most attractive is probably the highest market frequency of the RX480.
According to my previous experience, the RX480/RX470 core frequency is not good, they have tried 1400hz unsuccessful, ultra-platinum 1342 frequency, should satisfy many players with this requirement.
The actual performance is somewhat improved compared to the public version. Take Watching Pioneer as an example, it is probably a few frames faster.
The disadvantage is that the current price is more expensive, in addition to the current RX480 4G version is still not available for choice; but not CF, it is difficult to use 4G + memory.
