NV New card GTX1080 price ratio?

The next generation of graphics cards in 2016 came earlier-not until the June Taipei Computer Show, which Nvidia recently officially released Pascal's GeForce GTX 1080 and GTX 1070 graphics cards.

GP104 core specifications and before the news of the difference is not big, of course, the attraction of the bright spot or quite a lot of-radiator and the appearance of a new design, different styles,GTX 1080 core frequency is amazing, but also used 8GB gddr5x video memory, but the price of the card also from GTX 980 times of 549 dollars rose to 599 dollars, Faith edition is 699 dollars, then GTX 1080 worth buying?

In addition to the brand belief, the other things to see is performance and price, so we have to understand GTX 1080 first. At present Nvidia has not fully disclosed all the information of GTX 1080 graphics card, GP104 core transistor size, core area is not clear, the following table is currently known information summary:

Past flagship video graphics specifications comparison

We have compared GTX 1080, GTX 980 Ti, GTX 980 and AMD Radeon Pro Duo, R9 Fury x, GTX 1080 video card main replacement target is GTX 980 video card, but in the absence of GTX 1080 Ti, it is likely Also with GTX 980 TI a little competition, especially the price of the two closer.

From the core,GTX 1080 uses the new Pascal architecture, the 16nm FinFET plus process, the Cuda core number is 2,560, compared to GTX 980 2048 ascension 25%, but lower than GTX 980 ti 2816. TA texture unit and the number of ROP units have not been published, 160 texture units are based on the GP100 core of the SM structure calculated, for reference only, and the ROP unit is based on the video memory bit width to guess, its bit width is still 256bit,rop the number of units should be the same as GTX 980.

The core area and the number of transistors are not publicly available, but we have previously estimated the GP100 core transistor density, so the same 16nm process of the GP104 core should also have similar performance, but GP100 and GP104 in the double precision unit circuit is very different, so the size of the transistor compared to GTX 980 of the 5.2 billion will not increase by as much as a small number of people guessing about 708 billion transistors, the core area of 300-350mm2 around. (Update: The number of transistors is 7.2 billion, the core area is still uncertain.) )

　　thanks to advanced technology, GTX 1080 video card core frequency is very high, the base has 1607MHz, acceleration frequency 1733MHz , and GTX 980 is only 1126, 1216MHz, on the frequency of the increase of 40%, so GTX 1080 graphics card 9 Tflops floating-point performance is almost 80% higher than GTX 980, but a large part of the credit is increased by frequency, and the Cuda core increases by 25%.

　　memory aspect is the biggest change, GTX 1080 graphics card really ate gddr5x memory of crabs, frequency from the current 7Gbps to 10Gbps, bandwidth from 224gb/s to 320gb/s , but this bandwidth upgrade than HBM 2 is still very far, And the current gddr5x video memory is far from the United States to claim 12, 14Gbps so high, so GTX 1080 320gb/s than 384bit bit wide GTX 980 TI or weak point.

Video memory capacity This great progress, from the previous generation of 4GB jumped to 8GB, in the NVIDIA graphics card after GTX Titan X 12GB, but AMD early on the R9 390X graphics card on the 8GB memory .

Interface , the GTX 1080 graphics card has made overall progress, supporting HDMI 2.0b and DP 1.4, but the official also stressed that the DP 1.2 specification is certified, DP 1.3 and DP 1.4 specification is ready ready to support , may be not certified, after all, DP 1.3/ 1.4 Specifications now have few support, AMD also to the Polaris video card to support the DP 1.3 specification.

So much so, simply put, is GTX 1080 graphics performance than GTX 980 does have a significant increase, floating point performance increased by 80%, but the actual game performance may not be as much as you expect, because the total number of Cuda core increase is not much, mainly by frequency pull, memory bit width unchanged, bandwidth increased by 40 %, doubling capacity at the same time.

GTX1080 and GTX980 Graphics game performance Comparison

Nvidia official performance test, GTX 1080 of the VR performance is GTX 980 twice times more, but the game performance is to upgrade more than 50% points, considering that this is still official data, then the actual game performance will be much less, the estimated performance is similar to GTX 980 ti.

Performance promotion is on the one hand,GTX 1080 graphics card power consumption, heat problem is also important, its TDP is 180W, this is higher than GTX 980 165W, but we also have to take into account the core frequency increased significantly, CUDA core number also increased, And the TDP power consumption is not necessarily equivalent to the actual power consumption , at this conference Nvidia also demonstrated the GTX 1080 low power advantage, as shown in the following figure:

GTX1080 and GTX980 Power comparison

The peak voltage of the GTX 1080 video card is lower than the GTX 980 graphics card (correction: The voltage is fluctuating peak to peak) and the efficiency is higher than the GTX 980 graphics card, as noted by the reader. As for the effectiveness of the new radiator, there is no measured data, but the official GTX 980 graphics card, the highest temperature is 98°C,GTX 1080 is 94°c, which is a hint .

Finally, it's the price. GTX 1080 graphics card recommended price is 599 U.S. dollars, the founder of the version is 699 dollars (many do not know), this price than the original GTX 980 video card price of 549 U.S. dollars cost more than 50 U.S. dollars, and GTX 980 of the proposed price is only 649 dollars, Previous rumors of GP104 graphics card price increase in the information has been sitting solid.

Domestic prices , GTX 980 graphics card is 3999 yuan, GTX 980 ti is 4699 yuan, GTX 1080 graphics domestic price is unknown, but can be guessed not cheap, and far from exchange rate conversion over so simple, because GTX 980 ti Although is 4699 yuan, But this is only the lower limit of licensed prices, manufacturers on the sale of graphics card prices are generally more than 5000 yuan .

Just heard the rumor that GTX 1080 video card initial booking price is 6888 yuan, although the small weave think Nvidia really want to so priced is crazy, but this possibility is not not .... Because for a long time, the high-end exclusive market is NVIDIA only, AMD this year's Ploaris graphics card positioning is not high, Polaris 10 is R9 490 (x) level, the flagship video card or Fury X, recently released pro duo video card is dual-core, although the performance is stronger, But the price of 13999 yuan is not the average person can bear.

Comprehensive specifications, performance and price, GTX 1080 graphics card relative to GTX 980 and GTX 980 TI is no cost-effective, but this is actually a common problem of new cards, Nvidia in a strong situation alone how could make new cards to sell cheaper, business is not to do charity. Of course, the late GTX 1080 graphics card should return to about 5000 yuan or lower price reasonable level, then high-end players or more worthy of recommendation.

In other words,Pascal's energy-efficient, new look, radiator and interface are still very attractive for many high performance, if GTX 1080 can be similar to the GTX 980 TI World War, this situation is a little bit higher or understandable .
