Radeon RX 470D review, priced at 1299 yuan

PCB length is also different

Although there is not much difference when looking at the appearance of the radiator, you can see the secret by paying attention to the length of the PCB board.

Removing the back panel

That's pretty obvious, isn't it? The RX 470D is a little shorter, and the components on the back are more compact.

PCB board front

A simple comparison shows that the material scale of Sapphire RX 470D Super Platinum OC is exactly the same as that of Sapphire RX 470 Super Platinum OC. Although the PCB board is shortened, the density of components is improved.

Power supply module

The core adopts 4+1+1 phase power supply, and the inductor used is Sapphire's fourth-generation black diamond inductor, which has 25% higher electromagnetic conversion efficiency and 10% lower operating temperature than ordinary inductors. The coil has a built-in heat sink to better reduce the temperature. The materials used are at a relatively luxurious level among all graphics cards.

RX 470D Core

The cores of this generation of 400 series do not have model numbers marked. Surrounding the core are 8 512MB GDDR5 memory chips, making up a total of 4GB of video memory with a 256-bit bit width.

E-Best GDDR5 video memory chips

Disassembly summary: The PCB board is slightly shorter than RX 470, but the material used is not reduced, so the PCB will appear more compact, so its performance is also worth looking forward to.

Test platform description:

Test platform: The public platform is the consumer-grade flagship i7-6700K + Gigabyte Z170X-UD3 ULTRA, which can ensure that it will not become a bottleneck for the graphics card. In addition, the memory is 8×4GB DDR4 2133, and the power supply is Corsair's RM 850.

All A cards are from Sapphire... Koko, the purpose is to see how big the gap is between RX 470 and RX 470D, and then to see the gap between 470D and 460.

3D MARK Theoretical Performance Test: Since these three graphics cards are positioned to run the current mainstream games at 1080P, the difference lies in the level of special effects, so the running scores are still mainly Extreme and Time Spy, and the same is true for the following games. Summary of theoretical performance test: It is a surprise. You can see that the performance of RX470D is very close to that of RX 470, and the results are T (92%) and E (94%) of RX 470... However, since it is still too close to RX 470, the performance gap with RX 460 is still relatively large. However, such a result is really very good for users who pursue performance of 1,000 yuan cards, but how will the game performance be? Let's take a look together.

Game performance test : Since the super popular war game "Battlefield 1" was recently released, we quickly followed suit and added Battlefield 1's performance test. The other five are all currently popular games, which can well represent the actual performance of these graphics cards. Compared with the big brother RX 470 , the performance of the two is very close. Since both are from the same Sapphire Ultra Platinum OC series , the performance gap is roughly equal to the gap between the two cores.

Comprehensively looking at all games, the RX 470D can run smoothly at 1080P, medium and high special effects . The RX 470D is indeed a very good gaming graphics card for a thousand yuan. It is not an exaggeration to say that it has a very high cost performance in this range. (Only considering price and performance)

Platform power consumption test: In order to be closer to the real scene in players' daily application, and because they are both gaming graphics cards, only the full-load game power consumption and idle standby power consumption of the graphics card are tested here. ( Note: The power consumption here is not the power consumption of a single graphics card, but the total power consumption of the entire host) Power consumption test summary: Compared with RX 470, the power consumption of RX 470D is relatively close, which is also expected.

Graphics card temperature test:

After the graphics card is fully loaded, the core temperature stabilizes at 73 ℃. In fact, Sapphire's Super Platinum OC version's cooling solution is relatively strong among A cards, so this performance is considered average.

Full load radiator noise test: After full load, the radiator noise is 42.5 decibels, which is super quiet among mid-to-high-end graphics cards. Combined with the full load temperature above, you can actually manually increase the radiator speed to achieve a balance between quietness and heat generation, because 42.5 decibels are basically inaudible after being placed in the chassis.

PConline review room summary:

① Conclusion: AMD succeeded. The performance of RX470D is very close to that of RX 470. RX 470D can be regarded as a very suitable graphics card for you among the thousand-yuan cards.

②In terms of materials and core, the cost of RX 470D will not be much lower than that of RX 470. Finally, I would like to introduce other RX 470D partners.

Sapphire RX 470D Platinum Edition

The core frequency and video memory frequency are slightly lower than those of the Super Platinum Edition, and the radiator is actually the public version with a different color.

Output Interface

There is no need to introduce too much about Dylan's Cool Energy series, which is already a very classic and reliable model among A cards.
