Jingdong purchase, Jingdong responsible for after-sales, the price 3199-150-30 (white bar) = 2919 yuan, recently belong to a better price. Scheduled on Monday, Friday night delivery, delivered on Saturday. Use it, first come to conclusions, talk about the advantages and disadvantages. Evaluation content: Unpacking, stability testing, Tomb Raider 9, 4K HDR decoding, MadVR rendering test.
Let me talk about my computer configuration: 14 years in November with the computer, E3 1231; 82G DDR3 1600; B85itx; LG UD88; output color depth 10bit; usually used for office, watching movies, playing games. Chassis size 30cm25cm20cm, usually thrown in a cabinet under a desk inside.
So when I plan to upgrade the 1070, I find that only 3 cards can be used for my computer: EVGA 1080sc; Gengchao 1070; public version. The former is not yet listed. The latter does not have faith. Jingdong owns 2,949 plows and decisively. So, I received this on Saturday.
The materials used in this price conscience: non-integrated cooling, power supply is a separate heat sink, only the memory and core are integrated coverage, in this price is also reasonable. The metal front plate and the back plate are of relatively good value. Dual BIOS switching is better than nothing
The biggest advantage: short! The measured total length of the baffle does not exceed 27.1 cm. 1070 power consumption 150w, overclocking space is limited, the world of three materials stacked fan do not know what to think, like chasing double 10cm fan enough to suppress (EVGA is double 9cm). Note that this is a double 10cm fan, which means that this card will be a little taller than the standard height. 
Why chase the wind 1070. 1) A single fan can't stand the pressure of 100w+ TDP. It can only be a compromise. Previously used Gigabyte 960 itx, had to admire Gigabyte's design strength, but in fact the graphics card temperature and noise is still high. 2) In the dual fans, both MSI and Herd are dual 10cm fans, but the chasing price is lower, and MSI is more suitable for overclocking players. In addition, MSI is 28cm long and cannot fit into my chassis. 
Stable performance: Game frequency is stable at 1.95Ghz, Furmark is stable at 1.8Ghz, and temperature is stable at 82 degrees (28 degrees at room temperature). For a 30cm25cm 20cm itx air-cooled chassis is already very good. The fan is stable at 1600rpm with slight wind noise.
With the Legend of Tomb Raider 9 on hand, the Tomb Raider 9 has been tested. The Tomb 9 should be the most representative game in 2014 or so, with the highest 4K effect, and it can run smoothly. The GPU-Z recording frequency is stable at about 1940mhz.
4K HEVC 10bit/HDR playback , MadVR jitter/optimal quality setting, Jinc scaling, video computing engine takes up about 25%, GPU takes about 80%, and it can run perfectly. Remarks: The occupancy rate of 960 is above 80%, and only the optimal performance setting can be opened.
1080p 10bit H264 + SVP Insert Frame (Open GPU Acceleration) + MadVR Dither / Optimal Quality Set XBR Double Zoom + Jinc Scale. Using the Ice Fruit OP test (typically the most resource-consuming video), the peak rendering time is around 10ms, and it is already running perfectly. In the original 960 exam, it was impossible to open the GPU interpolation frame (must use CPU operation) and madvr at the same time. The madvr could open up the spline interpolation amplification at most, and it was estimated that Pascal's task acquisition performance improved.
Incidentally, this set of screens can already be compared with the cable algorithm of Sodafa TV. Similar models are generally more than twice as expensive as ordinary models. After buying TV, you can only pay attention to the panel and refresh rate.
Above, to sum up, if you do not need to significantly overclock, do not pay attention to peripheral hardware such as three fans or lights, then chasing 1070 should be the current best price of 2500 to 3000 graphics card, if you need a relatively short 1070, This is almost the first choice.
