The official announcement of GeForce GTX 1080/1070 — this is the real deja vu. Moreover double. Again, NVIDIA has played a proactive, because a year ago the California-based company time to hurry up and introduced the GeForce GTX 980 Ti is almost a month earlier Radeon R9 X. Then such a move was justified, because for the same cost cards have a similar performance.
GeForce GTX 1080 is the first graphics card with a chip, produced on 16 nm process
Secondly, it is obvious that the GeForce GTX 1080 and GeForce GTX 1070 is predomi thousandth series. Previously, NVIDIA has presented a complete GPU Pascal GP100. Most likely, next year we will see complete top: GeForce GTX 1080 Ti and/or GTX TITAN GeForce %Latin letter%. However, at this point in time, the GeForce GTX 1080 is the fastest single-chip gaming graphics card NVIDIA.

Specifications
The idea is that the most important technical innovation the thousandth generation of NVIDIA cards is a new architecture — Pascal. But throughout the presentation, CEO Jen-sen Huang (Jen-Hsun Huang seemed to have focused on this moment not more attention than, for example, of memory standard GDDR5X. And certainly did not go into any technical details. Much has been said about the new 16-nanometer process technology. The event, of course, important and historical, since it’s been five years since the release of the first 28-nanometer solutions. Besides, now and graphics have moved from planar transistors to three-dimensional. Pascal is used in FinFET technology, the contract manufacturer was the company TSMC.
A lot of time Jen-sen was paid to virtual reality. It is seen that NVIDIA is betting on this technology. But about DirectX 12, on the contrary, the head of the company said virtually nothing. This leads to some thoughts.
Features of new NVIDIA
For the first time in the graphics cards use memory standard GDDR5X. Fundamental differences from classical GDDR5 she is not, used faster chips, which operates at a frequency of 10,000 MHz. Last year AMD was first used HBM chip, which allows to increase memory bandwidth of 512 GB/s Limiting factor that affects the performance of such graphics cards as Radeon R9 NANO/Fury/Fury X was a small amount — only 4 GB. The second generation solves this problem and doubles the bandwidth. Therefore, we conclude: if NVIDIA does not use HBM2 the GeForce GTX 1080, so the technology is not yet ready for commercial implementation. AMD on the Polaris architecture is similarly limited to use GDDR5/GDDR5X.
HBM memory will not. But will chip GDDR5X the production of Micron
The first accelerator “green” c HBM2 will appear only next year. They will be professional graphics card Tesla P100, is equipped with stacks for a total volume of 32 GB. Perhaps 16 GB HBM2 will receive either a GeForce GTX 1080 Ti or another “Titan”.
NVIDIA GP100
The table below shows all known specifications of the GeForce GTX 1080. The graphics card uses the graphics processor GP104 with a budget of 7.2 billion transistors. By the way, full GP100 received 15.3 billion transistors.

NVIDIA officially revealed just a small list of characteristics. We know that GP104 chip used in the GeForce GTX 1080, got 2560 CUDA cores. In the full processor — GP100 — involved 3840 CUDA cores. They are divided into streaming multiprocessors (SM), 64 pieces in each. The basic unit is a cluster of graphics processor. It includes ten SM. Then it turns out that GP104 consists of 2560/640=4 clusters and graphics processor has 4×10=40 streaming multiprocessors and 160 texture units (as the GP100 — 240). Here’s a simple math.
The memory chip GDDR5X
Processor GP104
It turns out that the GeForce GTX 1080 CUDA cores and texture units is less than, for example, the GeForce GTX 980 Ti. However, the main thing — not the quantity but the effectiveness of one or another component. For example not far to seek. Is GeForce GTX 970, the graphics card 104 texture units and 1664 CUDA kernel. There are GeForce GTX 780, it — blocks 2304 and 192 respectively. Only here in games these adapters at least equal to, but often more modern model is much faster. It is therefore right to compare the technical characteristics of video cards of the same generation, and all the others will judge FRAPS.
The block diagram of the processor GP100
The second point, which is really amazing, is the clock rate GP104. Nominal 1607 MHz in the Boost mode, turn to 1733 MHz. In this presentation demonstrated an overclocked version of the GeForce GTX 1080, where the processor functioned at a speed of 2100 MHz and the memory at an effective frequency of 11 000 MHz. Well, we can expect a large number of custom versions of the flagship with alternative cooling and a decent factory overclock. And records on the same hwbot.org will fall one by one.
NVIDIA GeForce GTX 1080
The maximum consumption of the GeForce GTX 1080 does not exceed 180 watts. Wonder this state of Affairs is not necessary.
Reference model for normal operation requires one 8-pin power connector of the power supply. According to NVIDIA, then under load the CPU is heated to 67 degrees Celsius. I note that reference modification of the GeForce GTX 1080 uses the classic cooler with a vaporization chamber and a turbine-type supercharger.

Another interesting point. At low power, when the adapter consumes less than 100 watts of power, the efficiency of the GeForce GTX 1080 is chosen close to 90%. Have a GeForce GTX 980 with an index of 165 watts, the efficiency is much lower. Affects a smaller variation of the voltage supplied to the processor during operation: 120 MB vs 209 MB.

Performance
Of course, the most important thing in any gaming the video card is the performance level. At the presentation the head of NVIDIA openly declared that the GeForce GTX 1080 faster SLI array GeForce GTX 980 and more nimble than the 1000 dollar GeForce GTX TITAN X (if you believe the charts, but somewhere in the 20%). The new flagship uses 30% less energy. Total peak power GeForce GTX 1080 is 9 TFLOPS. Maxwell solutions on this indicator seriously inferior to the newly made king “green.”

In VR the difference between the GeForce GTX 1080 and Maxwell-by family only increases. Total: there is a two-fold superiority over the GeForce GTX TITAN X games and triple — a in energy efficiency.

After studying the specifications and analyzing all kinds of leakage of information in such the superiority of the GeForce GTX 1080 on GeForce GTX 980/980 Ti/TITAN X very hard to believe. Whether there will be with the release of the GeForce GTX 1080 Ti.
GeForce GTX 1080 20% faster GeForce GTX TITAN X
The presentation was launched a new DOOM. At the maximum graphics quality settings in Full HD resolution, the average FPS was approximately 120 units. The game run with the software interface Vulkan. But DirectX 12, again, due attention to “green” for some reason did not pay. Although I can guess why…
The performance of the NVIDIA GeForce GTX 1080 comparison with NVIDIA GeForce GTX 980
Leaks performance GeForce GTX 1080 abound. Below are the results in the popular benchmark 3DMark, and in the Ashes of the Singularity. And yet to treat these results offer with some skepticism. Will wait for full reviews.

Prices
As you can see, on paper performance and energy efficiency from the GeForce GTX 1080 is all right. The success of the flagship, of course, will determine the price. And then green went way above and beyond. For all the major innovations NVIDIA always develops a reference sample. A kind of “reference point”. Is this model cheaper custom versions from partners. Now Jen-sen and his team strictly regulate the price of standard versions — so-called Founders Edition. They will go on sale at a strictly specified price: 700 dollars for the GeForce GTX 1080 and $ 450 for GeForce GTX 1070. A smaller price tag — MSRP — applies to adapters that use alternative cooling and the PCB Board. Agree, looks not so appetizing, right? The intrigue lies in how much producers wish to throw some money for a better quality cooler with cooled heat pipes to transmit and multiple fans, as well as for factory overclocking. Do not rule out a scenario where the recommended graphics cards for $600 and $380, we will not see at all. On sale the GeForce GTX 1080 will arrive on may 27.

The most offensive that NVIDIA did not disclose the characteristics of GeForce GTX 1070. Known only to the price, as well as peak performance Junior pratapa — 6.5 TERAFLOPS. Plus the fact that you are using the standard GDDR5 memory volume of 8 GB. It turns out that the novelty papermache with a GeForce GTX 980 Ti and Radeon R9 X, but at a price of 380-450 USD the winner is known in advance.
A joke about the fact that on may 6 all Maxwell video card officially turned into a pumpkin, flooded the Internet. However, to write off from the accounts of the range of GeForce GTX 900 premature, since only two video cards. Besides, in sale they will arrive in June, but only by the end of summer when the excitement subside and will curb your appetite enterprising merchants, will be able to buy a novelty at a price close to the recommended. Interestingly, the memory GDDR5X on the conveyor ITC will deliver only in the summer. Therefore, some analysts predict a deficit of GeForce GTX 1080 until September-October.
Referens more expensive custom bikes — it happened the first time
In the fall, if you believe the rumors, green will present a few graphics cards below the rank. During this time the remains of a GeForce GTX Ti 960/970/980/980 needs to be sold. Naturally, at lower prices. And while the situation looks as follows:

Thus, the “greens” made the first move. As soon as the GeForce GTX 1080 and GeForce GTX 1070 will reach us immediately we will test and share your impressions. At the same time, wait, how and, most importantly, what answer AMD, because very soon the world will see the first video cards on the architecture of Polaris. May and June will be hot!
