About the suffix "D" of RX 470D, AMD official statement is -- "D" refers to "Dragon", Dragon, a very sacred creature with Chinese culture, because this paragraph
RX 470D is China-specific.
● Clear purpose-lock GTX1050Ti
I have analyzed it many times before. The performance fault and price fault between RX 470 and RX 460 are very large. AMD must also need a model to fill this gap.
Are you willing to wait for the opportunity to create an enemy? Or is it the product of a hasty attack after seeing the weakness of 1050Ti? I think it's the latter, but it doesn't matter.
If you buy better performance at the same price, it is a good product.
● Core: the RX 470D is castrated by the RX 470
Just like the relationship between RX 480 and RX 470, RX 470D shields some stream processors based on RX 470, as shown in the figure below.
Specifications:The shielding routine is completely unchanged. RX 480 minus 1 set of stream processors (256) and minus 16 texture units will become RX 470; RX 470 minus a set of stream processors and 16 texture units to become RX 460D. If we ignore the frequency difference between different brand models, the performance decline between the three should be the same.
The memory size is still 4 GB, which is also the most suitable for this core memory.
RX 470D is a Chinese model,
So there will be no public versionMost of the models available on the market will be in the form of high-frequency versions, so the sapphire RX 470D ultra-Platinum OC used today is also representative, its frequency, workmanship, and materials will all be the presence of a stream of major a card brands. Of course, the price will also be slightly higher ~
AMD for RX 470D
Official Guide price: 1299 yuanThat is, the actual price will fluctuate up and down based on it. GTX1050Ti's official guide price is 1199 yuan, and the price is in the same range, the war is inevitable.
● Sapphire RX 470D platinum OC dismantling
At first, I expected that this would be the product that the sapphire RX 470 Ultra Platinum OC edition shielded from the core. As a result, I found that I had guessed it wrong...
Can we see the difference?
Graphics card backplane
The design of the backboard is different. The central opening of the RX 470D backboard is larger, but the style is the same but the pattern is a little different. In addition, the power supply interface of the RX 470D is designed in the upper left corner, therefore, the backplane also opens a gap.
The RX 470 power supply interface is designed on the video card side, while the RX 470D is on the top of the video card and is a hidden design. After the power supply is connected, the 8Pin plug will not be protruding.
Display output
The two are exactly the same. The dual-card slot design, dual DP port, dual HDMI port, and DVI interface support multi-screen output.
RX 470D has no old brother's LED switch key and one-click superfrequency button.
Although only look at the appearance of the radiator is not much difference, but pay attention to the PCB length can be seen Xuan machine.
This is obvious, right? RX 470D is shorter than a small cut, and the back components are more compact.
In simple comparison, we can see that the scale of the Sapphire RX 470D Ultra Platinum OC is exactly the same as that of the Sapphire RX 470 Ultra Platinum OC. Although the PCB is shortened, the component density is improved.
The core uses 4 + 1 + 1 phase power supply, and uses the fourth generation of black diamond inductance of sapphire as the inductance, which is 25% more efficient than ordinary inductance and 10% less operating temperature, the coil has a built-in heat sink to better reduce the temperature. Materials are relatively luxurious in all graphics cards.
The core of this generation of 400 series did not mark the model.
Around the core is 8 pieces of MB GDDR5 memory particles, constitute a total of 4 GB memory, bit width.
Disassembly Summary: PCB board length is slightly shorter than RX 470, but the materials are not reduced, so PCB will appear more compact, so its performance is also worth looking forward.

Test platform description:
Test platform:Public platform for the consumption level flagship i7-6700K +
Gigabyte Z170X-UD3 ULTRATo ensure that it will not become the bottleneck of the video card. In addition, the memory is 8x4 GB DDR4 2133, and the power supply is RM 850 of the pirate ship.
All a cards are from Sapphire... coke, this evaluation uses the six most affordable graphics cards for comparison, the goal is also very clear, the most important thing is to make RX 460D compared with NVIDIA GTX1050Ti, the second is to see the gap between RX 470 and RX 470D, and then the gap between 460 and.
● 3D MARK theoretical performance testing:
The positioning of these 6 graphics cards is p to run the current mainstream games, the difference lies in the level of special effects, so the running points are still
Extreme, Time SpyAnd the following games.
To make it more beautiful, the brand and model of the video card are not included in the comparison list, and only the core is marked. In addition, the video card will be sorted by the official guide price of A/N from high to low. This will make it more intuitive.
Summary of theoretical performance testing:It was just a surprise. We can see that the performance of RX 470D is very close to that of RX 470. The result is that RX 470 T (92%) and E (94%) are much better than GTX1050Ti... however, because it is still too close to RX 470, the performance fault with RX 460 is still too large. However, this result is really good for thousands of card users who are pursuing performance, but what will happen to the game? Let's take a look.
● Game performance test:
Because of the recent emergence of the super fire war game Battlefield 1, we also quickly followed, joined the performance test of Battlefield 1, the remaining 5 are currently popular games, it represents the actual performance of these graphics cards.
Game Test summary:The result is really surprising. What Is RX 470D?
It is significantly better than GTX1050TiBasically, you can finalize that, if you are only pursuing performance, adding 100 yuan to buy RX 470D is much better than GTX1050Ti.
Next we will compare our eldest brother RX 470, The two are very similar, because both are from the same
Sapphire platinum OC seriesThe performance gap is probably equal to the gap between the two cores.
Let's take a look at the GTX1060 3 GB with an official guide price of 1599 yuan. The two are winning and losing each other, but the overall view is still GTX1060 3 GB. After all, the price is not in the same range.
Based on all the games,
RX 470D can run smoothly in 1080 P, medium, and high effectRX 470D is indeed a game video card with good performance of RMB.
Is the most cost-effective. (Only price and performance considerations)
● Platform power consumption test:
In order to be closer to the real scenarios in the player's daily applications, and they are all game graphics cards, we will only test the full power consumption of the video card game and idle standby power consumption.
(Note: The power consumption here is not the power consumption of a single video card, but the total power consumption of the entire host)
Power consumption test summary:RX 470D is a castrated product with the same core as RX 470, so the power consumption must be relatively close, and this is expected in terms of the energy consumption ratio, AMD's current generation indeed lags behind NVIDIA, so this is also a breakthrough in GTX1050Ti. The analysis will be detailed in the final summary.
● Video card temperature test:
After the video card is fully loaded, the core temperature is stable at 73 ℃. In fact, the cooling solution of sapphire platinum OC version is also strong in the card, so this performance is quite satisfactory, on the other hand, it also shows that this generation of AMD Core fever and power control is still inferior to NVIDIA.
● Noise test of full-load radiator:
After full load, the noise of the radiator is 42.5 decibels, which is the most quiet in the middle and high-end graphics cards. Combined with the above full load temperature, the rotation speed of the radiator can be increased manually, to achieve the balance between mute and fever, because after 42.5 DB is put into the chassis, it is basically impossible to hear.
Noise:
0-20 decibels: very quiet, almost not feeling; 20-40 decibels: quiet, as if to whisper; 40-60 decibels: General indoor conversation; 60-70 decibels: noisy: lossy nerve; 70-90 decibels: very noisy, damaged nerve cells. 90-100 decibels: increased noisy and impaired hearing. 100-120 decibels: Unbearable. Waiting for one minute is temporary hearing loss. More than 120 decibels: extremely deaf or all-deaf; about 300 decibels or more: 20km people cannot repair their hearing loss.
● Comprehensive price/performance comparison:
Players in this price range may be sensitive to the video card price, so we have added the corresponding core A/N official guide price for reference. We can see that, if we only consider the price and performance, on the Qianyuan card battlefield, the performance of RX 470D is much better than that of GTX1050Ti, it is indeed the most suitable hardware and equipment for gaming players who are pursuing performance but have limited budgets.
Note:The comprehensive comparison of this evaluation may be different from the previous GTX1050Ti performance because the game selected for the two evaluations is different, but the actual performance gap does not change much, small fluctuations are also very reasonable.
● Graphics ladder diagram
The performance gap between the RX 470D and the RX 470 is not big, but it is slightly lower than the RX 470, so it is still much better than the GTX1050Ti.
● Evaluation summary:
Conclusion: AMD sniper attack is successful.
① RX 470D features very close to RX 470, far better than GTX1050TiThe official guide prices for RX 470D and GTX1050Ti are only RMB 100, so if you only pay attention to the cost-effectiveness factor, the RX 470D is definitely the most suitable for your graphics card.
② From the perspective of materials and core, the cost of RX 470D will not be much lower than that of RX 470Why don't I use RX 470 to reduce the price and GTX1050Ti just face it? AMD does not want everyone to figure out a GTX1050Ti counterpoint card. Instead, it wants to use RX 470 to match GTX1060 3 GB, therefore, you need this video card to go to the top of this position. But we do not need to pay too much attention to the underlying reasons. As long as we can get better performance at the same price, it is a good product, right?
③ Power consumption and energy consumption ratio are still hard for AMD.And this is not a short time to catch up, and GTX1050Ti breakthrough is here --
Dedicated to low power consumption, small size, no external power supply cardBecause of the front-end performance, no matter how you increase the frequency, it is difficult to beat RX 470D, but if it is more than power consumption and volume, the inherent advantage of GTX1050Ti is shown.
