When testing the GTX1080 with the RX480 CF recently, it was found that the 8G memory of the RX480 single card case appeared redundant in many games. The legendary RX480 4G is currently not listed on the domestic market. However, at the beginning of the month, the RX470/460 was listed.
Looking at the next specification comparison, compared to RX480, RX470 has relatively few core castrates and the frequency is even the same. Compared with the previous 4850 era, the relationship between 4850 and 4830 is somewhat similar.
The RX460 is clearly not at the same level.

The same is true, individuals are also more interested in the actual performance of the RX470, especially in the end with the RX480's performance in the end, so after the recent RX470 will get a card to test. At present, the first batch of listed RX470 is not much, and finally chose XFX's black wolf evolution.
Packaging is still in the X-style of XFX 
Actually there is a power adapter cable. . . This generation of cards began, and many manufacturers did not send any adapters at all. Even GTX1080 (public version) did. 
The default protection film and gesture 
The appearance of the graphics card is still a standard 2 fan heatsink setting. The length of the graphics card is medium, and the backplane is of course a reserved item. When the RX480 is released, the public version of the card, XFX is a standard backplane, and it also lets you Stand out from the brand, really is a boy
Relative to the public version of the RX470/480, the image interface, the DVI port is still retained.

Radiator analysis
XFX has basically claimed its own style in the standard heatsink of the graphics card. The material design of the entire program is quite mature. Modular fan, easy to clean; Although it is a mid-end model card, but the radiator is still the same as the 2K+ level (copper bottom, insert, 8mmX3) settings; of course, there is a reinforced backplane. 
PCB and power supply
In fact, the basic plan with the RX480 is universal, and the core size is also. 
Of course, the most important thing is the actual performance of the graphics card.
testing platform
CPU I5 6600K (overclocked to 4.5G)
Radiator Anime T40F Radiator
Motherboard Colorful Rainbow Z170X Flame Ares
Memory Zhi Qi DDR4 3000 8Gx4
SSD Kingston HyperX Predator 240G
System Windows10 (system and driver are updated to the latest)
GPU-Z recognition of the graphics card 
Temperature test, room temperature 26 degrees, bare metal environment
With a full load of 64° and a fan speed of around 2200, noise is acceptable. 
Theoretical testing
Directly tested 3DMARK's Ultra, Extreme mode, there is the Time Spy test; by the way compared the RX480 public version of the test data, we can see that the RX470 performance is very close.
In the Steam VR test, the scores are the same as those of the RX480. The overall score is 6 points and there is no speed below 90 frames. 
What about actual game testing?
Personally selected several more mainstream games, such as dota2, watch pioneer, CS: GO and GTA, should be considered game group audience with reference significance is also relatively large. The resolution setting is basically in the 1440p (that is, 2K) resolution, although 1080p resolution is the most popular settings, but this generation of new cards (except RX460) performance improvement is quite obvious, basically can run 1440p resolution The game is also relatively good to pull the limit.
CS:GO: The effect is the highest, AAAF is also on, and the average number of frames can exceed 200
Dota2: set the same as above, the highest, the average number of frames is also close to 140 
Watch Pioneer: One of the most popular games in the near future, 1080p resolution is naturally worth noting. The main test is 1440p resolution. The map selects the Lijiang tower battle map, and the average frame number just stabilizes at 60 frames, while other maps have more than 60, there are also 5x, and overall this is just 60 in this FPS stable value. Of course, users of 1080P can play 150% or 200% rendering smoothly. 
GTA5: Typical representative of eating resources, basically can represent all major games. On this side, we tested the different resolutions of 1440p and 1080p, because even in the 1080P, the average number of frames is 4x, basically it can play smoothly, and the 1440p basically reduces the average effect of 27.3. In addition, in the case of GTA5 1440p, the memory can basically take up to nearly 4g. 
Conclusion:
Recently, because it is worth buying the public test 1080, so just by the way just get a lot of card tests, including different resolution scenes (1080p, 1440p and 2160p), obviously feel RX480 and GTX1060, there is a problem, that is, memory redundancy compared Seriously, if RX480 does not have CF, it rarely has a chance to use 4G+ memory. If 4G+ video memory is used, the core budget is not enough. Even if the actual game is enough, it will not run fast, so CF When dual cards are used, the use of video memory will be more reasonable.
The emergence of the RX470 4G makes up for the vacancy in this price graphics card. Although the GPU part has been castrated, it is not serious, the performance is basically the same level (less single digit frames), and the decrease of the video memory significantly reduces Polaris’s Price, performance, then basically covered the largest range of 1080p and 1440p this user group, and the current RX470 is still just released stage, after the price adjustment and streamlined version of the on-line, it is estimated that the price will be even better. The same is true, so the GTX1060 3G version has also been reported in the near future. However, it is known that the RX470 has the most direct advantage of bridging the CF, and 1060 definitely does not support SLI.
As for the XFX RX470 Black Wolf Evolution, the graphics card itself has set the same level of workmanship as before, but when everyone is almost similar, why not do some differentiation, such as short cards, RX470 this level of card, is better to do a short card, and At present, many ITX players lack the exquisite short card.
QAtime: With regard to the purchase of the thousand-digit price display card, I will continue to sort out the answer here.
1,
Q: What is the use of graphics card backplane?
A: Generally, it is used to harden the graphics card PCB to avoid the core imaginary welding caused by distortion of the graphics card PCB. The auxiliary function may be to enhance the cooling of the graphics card (the effect is not very strong), and it can also prevent the installation process from accidentally bumping. To the back of the video card electronic originals. In general, it is a good setting, but it does not have to be forced.

Q: How to clean the graphics dust
A: First brush lightly with a brush, and then use a hair dryer or compressed air to blow off the dust; this time the XFX's removable module fan design is very convenient.
3,
Q: What is the difference between the HDT heat pipe contact of the graphics card radiator and the traditional copper bottom/aluminum bottom process?
A: Performance shows that the difference between the two methods is not significant, but the traditional copper bottom / aluminum bottom cost will be more expensive, the processing process is also relatively large, so the general high-quality radiator is more commonly used, but it can not be simple It is said that the performance of the two is high because it is also related to other parts.
4,
Q: How to select the video memory size?
A: The graphics memory size is recommended to consider the core and resolution. The larger the resolution, the more memory that is needed, and the more anti-aliasing effects such as AA/AF, the more memory the better the theoretical memory, but the actual GPU computing power. Also to a certain level in order to effectively eat a certain degree of memory, with the recent popular RX480/GTX1060 as an example, in the case of the 1440P in the GTA5, it is possible to use 4G+ memory, but the problem is at this resolution Next, RX480/GTX1060, the core computing power can only keep the game at a speed of about 30 frames, not smooth, but to smooth either reduce the resolution or turn down the special effects, so after optimization, memory usage is basically 2G-3G Left and right range, memory over 4G plus + is obviously wasted. Of course, RX480 itself is a good point to support CF, RX480CF computing power after CF is strong enough (after CF memory is calculated by 8G, not 8G+8G)
