On June 29 this year, AMD finally released its first GPU-Polaris 10 with 14nm FinFET technology. The first product to be released is the RX480, which has 2304 stream processors and 8GB of 8Gbps GDDR5 memory.
Perhaps everyone's expectations are too high. Perhaps it is AMD's own chaos, perhaps AIB pig teammates. In short, the sale of RX480 can be described as twists and turns: first, Jingdong's pre-sale is slower than spot delivery, and spot customers can also use discount coupons. Equivalent to pre-sale of a belief; and then burst out of RX480 in overclocking state will take too much power from the motherboard, then AMD introduced a new driver to fix this problem (but I really do not burn the board this thing is suspicious, after all, so much global Only one person on the card stated that the motherboard was burned, and the details of the picture were still hidden. However, the overclocking of excessive pre-clock overclocking from the motherboard actually existed; later, the non-public version of the sale was dragged and dragged down until the opponent's GTX1060 was undeclared. Listing and access to the line to do the price of 1999 (based on Jingdong prices, the so-called driving is easy to overturn, there is a problem Taobao shop repair is very troublesome), here are several first-line brands have not shipped, the price is higher Out of 1060, not to mention the channel brand, not only the price is not, even the time of delivery do not know ... ...
After thinking about these things, RX480, as AMD's only new card, bears a lot of pressure and responsibility. It is necessary to withstand the gap between the 390 and 390X production discontinuities and to replace its predecessor 380. From 1699 (380X 4G) to 2799 (390 8G), he only has a product of the public version of 8G 1999, and then faces the opponent's various products. The performance is currently slightly lower than the rival GTX1060, and can compete with the 1060. The injustice of the non-public sector has not come yet. It is really stressful.
Fortunately, the problem of lack of AMD's new products will soon be alleviated, and it is a gap in the layout of its competitors: the market below 1699. This product is the RX470 that we want to see today.
Relative to the older brother RX480, the RX470 of the Polaris family's younger brother has shrunk to a very small scale, maintaining AMD's usual style: only stream processing has reduced by about 10%, from 2304 to 2048, and video memory has also abandoned high costs. Production is too low. The highly sought-after 8Gbps chips switched to the widely available 7Gbps (the public version runs at 6.6Gbps, but all the cards I've seen are running 7G...) The frequency is slightly lower, and the total power consumption drops. To 120W, the rest of the knife did not move, basically the card's performance in the specifications came out after the number of hearts ...
Unlike the RX480, the RX470 does not have a public version of this sale (only one uses a public-private version of the Sapphire Platinum), all non-public version of the form, the first shipment also only 4G version, so the frequency of affirmation All of them are higher than the public version. This time I got the RX470 black wolf that has always been in the XFX XFX.
RX470 black wolf evolution looks and RX480 black wolf evolution looks a bit like, the difference is that the entire card is a little short, only about 24 cm, PCB even shorter, radiator structure is also different from the RX480 (according to RX480, 470 It is designed by two teams at the same time).
The light of faith still remains, but as the length is shortened, it is adjusted from the middle to the interface side.
Because of the drop in power consumption, the RX470 only provides a single 6-pin power supply interface with a maximum power supply capability of 75+75 watts.
The design of the backplane is similar to that of the RX480, but it has been reduced in size to fit the PCB. In addition XFX also has a RX470 black wolf, it seems that there is no backplane, but the price is lower.
The interface, in addition to the public version of 3DP 1.3+1HDMI2.0, complements the DVI interface. What is VGA or early elimination.
The radiator, using three thick 8mm heat pipes, is not nickel-plated and looks full of muscle. The core part uses a whole block of copper for contact.
The fan is still a special patented detachable fan of the Black Wolf series, which is very convenient for cleaning dust.
The size of the heat sink is approximately 66185mm, which is ample for a 120W core.
RX470PCB's real body, the overall program is very similar to the RX480 public version, but it is 4+1+1 phase power supply, external power supply with the same 6P.
Power supply and memory, the first batch of RX470 products are 4G memory, because the official positioning of RX470 is "HD Gaming", so 4G memory is fully enough, RX480 configuration 8G memory is more for dual-card considerations, and delay Not seeing the large area spread of the 480 4G is also believed to be too close to the 470 4G.
RX470 core real body, produced in 16 years and 18 weeks, and RX480 version of the public production in the same week, so this card is not it can also open the nuclear chance to try, but unfortunately the current 480 BIOS memory is Samsung, try a brush Into the black screen
On the back of the PCB, you can see that the card actually supports 8pin... but I actually smoked just 150W in the actual test, so 6pin is enough.
The backplane, although fully covered by the PCB, does not provide additional auxiliary heat dissipation for the memory or core, such as making a thermal paste.
It's okay for the next dry goods:
The frequency of this card is set at 1256Mhz core/1750MHz memory, almost the same as the public version of RX480 4G 1266Mhz/1750Mhz frequency, so the performance gap is basically the core size of the gap, but I do not have the legendary 480 4G, only A XFX public version, running at a frequency of 1288/2000 Mhz, for reference. There is also a comparison of the same price GTX960 4G (first-line public version of Jingdong 1599), and a higher grade of GTX970 3.5+0.5G (PS I would like to ask 30 US dollars in the hands of domestic users may have two 970 hands It runs on Max Boost 1278Mhz and Max Boost 1329Mhz, respectively, of which 960 is the public version design, and 970 is the non-public version of the double fan.
testing platform:
CPU: Intel Core i7 z
Memory: DDR4 2400 8G X4
Motherboard: ASUS ROG X99 Strix Gaming
Power Supply: Haiyun P1000
Limited time, just got the card soon, in order to explode as soon as possible, run the theory test it...
The first is the main attack direction of the RX470. The Firestrike running at 1080P resolution is very free to run out of 11564 points, easily over 10,000.
The 1440P FSE, by default, also exceeds the 5000 mark, and only 117W, 75 degrees, but unfortunately only ran out of the highest frequency of 1250 (FS that forgot the screenshot ...) GPUZ power consumption and my power meter reading Basically the same, the power meter shows 280W input, I standby power consumption of this platform is about 120W, so calculate the power consumption up and down 120W is no problem.
4K set FSU, run out of 2548 points, relatively speaking, a bit difficult.
1440P, DX12's TimeSpy, with a score of 3527, seems to be competent for the DX12 era's 2K resolution or barely.
The Benchmark game at hand has only one ancient tomb. The latest version of the drive has caused the performance of the Polaris10 family to soar by 15%.
In the case of 1920,1200 resolution, the highest preset + FXAA, ran out 60fps good results, to know that in the last drive in the 480 is just this level ...
The most important theoretical performance comparison, RX470 acquiescence in the 1080P even surpassed the non-public version of the GTX970, even slightly lower in the 4K, DX12 2K, only 2K FSE fall defeat, the reason I do not know, repeat the test a few This is the case all the time... The gap between 480 and 480 is still around 10%, which is slightly smaller than the difference in size (note that my public version is running at overclocked version of 1288MHz). DX12 will not say it. This is the traditional advantage of GCN.
Also add that, although AMD did not mention this matter, but the RX470 default test VR performance reaches 6.3 points, can run VR games smoothly, is the current cheap VR Ready graphics card.
Overclock performance, in which PL stands for PowerLimit in the power consumption limit of the drive panel. I have measured the +20% and 50% of the time in limited time. In addition, I simply measured the gap between the same frequency and the 480 core. The last MAX is running. 1360/1800Mhz.
It can be seen that in the default frequency fixed mode (PL+50%), the performance of the RX470 directly follows the RX480 public edition. If you calculate the difference between the core frequency of 32MHz and the memory equivalent 1000MHz, you can think that the 470 is in the constant frequency mode. Performance under = 480 default performance!
No wonder the RX480 4G version has been reluctant to show up, because the 470 4G is too strong...
Finally, the test results of power consumption, temperature, and some of the ancient tombs 10, of which the power consumption is determined using the GPUZ reading + power meter readings, originally wanted to measure the noise, but the summer air conditioning has been driving too loud and can not be measured, so Only these.
In terms of power consumption, the energy consumption of the RX470 is similar to that of the 480, and it has reached Maxwell's level. The maximum power supply is no more than 150W, which is a little better than the RX480. However, this GTX970 is non-public version, power consumption is much higher than the public version, but the performance is also higher, right for reference.
Temperature dual fan can be suppressed under 80 is very good, but although it seems that the temperature is similar but the noise is not a level, the default fan is 2600-2700 rpm or so, and after overclocking will exceed 3,000 rpm, this time the noise is still relatively Obviously, and when the public version of the 2800 rpm noise is almost the same, but if the 480 public version carefully adjust the heat curve is not hot and it is not noisy, the premise is not to overclock...
Finally talk about the pain points of AMD players: price. AMD's products have always been known for its good price/performance ratio. This time, Polaris10 products were listed on the domestic market. We do not know if AMD is priced at death or AIB is priced to death. The price of RX480 is very poorly understood: The foreign 8G version is 249 US dollars (229). The US knife was later proved to be false.) In China, the tax figure is about 1950 yuan. Selling 1999 yuan is still reasonable. The non-public version is a price of 2299, 2399. However, it faces the non-public pricing of the opponent. 2399. The GTX1060 cofferdam of the Non-Public 1999 roads not only does not make up for the performance (the current news is that the non-public 1060 and 480 performances of the 2399 are 55 open, but the 480 version of the 1999 hits the 1999 GTX1060). The goods are also very disadvantaged (currently non-public version of the black wolf only evolved to a small amount of 2399 high price shipments, and several other non-public version has not yet begun shipping, and the opponent's 1060 has completely covered the 1999-2399 The market is even more embarrassing is that many NV channel providers have also come up with a "drive", forcibly put a lot of non-public version of the channel three-line GTX1060 to 1799,1699 low prices, what to pull the player's psychological price to this Grade, RX480 was even more embarrassed. However, I would like to say that the purchase of electronic products is still to be purchased in JD.com or the official Tmall store. The so-called "drive price" does not include invoices. Many businesses even require tearing off the serial number, which is equivalent to giving up the warranty directly. This is very Wise (I think this is Aunt Zhang has never pushed Taobao C store price reasons, recently broke the GTX1070/1060 Huaping problems, particularly prominent in the cheap models, specific you can look at the graphics card bar related posts, there have been The manufacturer released the announcement. I believe it was not fabricated in a vacuum. At this time, the "drive card" is very embarrassing.) And many of them are snapping up, just like the 1 yuan in the mall to buy a mobile phone and hang yours.
Say back RX470 price. This time many businesses hit a predetermined price of 1599-1699, compared to the foreign price of 149 US dollars, expensive? You are dead! However, note that 149 US dollars is the public version of the proposed price, which is about 1199 yuan, and there is no public version of this initial product, are non-public version of the first-line brand , usually more expensive than the public version ( NV's front-line public version is generally slightly more expensive than the public version before this FE belief version comes out. It is not possible to take those paths non-parallel, and Sotec for the Pakeng Plant is second-line in the NV camp. Sapphire is absolutely AMD. Line, so I think the price is reasonable between 1399-1499. Fortunately, after the impact of the 480, various AIBs also opened up, sent games to send games, gifts to send gifts, the official store to drive a limited number of cars (foreign, I think actually called "limited offer to buy" is more reasonable, saying Up the official Tmall shop to drive is also playing 666, but also with invoices , direct price cuts are incredible ...), the overall price to get up and down at 1,500 yuan, combined with its performance, I can only say that RX470 is still the current price The king of cost-effectiveness, even in the face of 1699 driving price GTX1060, is also true, its performance gap and price gap is basically proportional to. Jingdong's pre-sale game was a lot tricky this time. There are currently no Jingdong price announcements. The news I got is likely to be set at 1599 (can't be used) or 1699 (can be used), combined with Jingdong. The positioning, as well as the advantages of invoices and warranty, are still relatively reasonable (but still more expensive than foreign). However, the warranty is absolutely black spots, perhaps due to the mine disaster that year, in addition to not be concerned about the big brother ASUS, the amount there is a path Yeston, A card is the rest of the two-year warranty, NV sideline are basically three The annual insurance, second-line and access roads are also quite a few. This depends on how you choose. However, I think that unless you support personal insurance, JD.com is still the first choice because you don't know when the store will be gone...
Of course, based on the performance of the RX470, is it worth noting that the card with this performance is worth 1,500 yuan? value! If you can really do 1,299 yuan, it is not impossible to reproduce the grand occasion of 9550, this is AMD's dessert card killer!
Next, it depends on how NVIDIA took the card.
