Nvidia GeForce GTX presented in 1080 and 1070 with Pascal GPU
Nvidia has its first two GeForce graphics cards announced by Pascal GPU. The top model, the GTX 1080, is equipped with 8GB gddr5x memory at speeds of 10GHz. Nvidia claims that the video card in VR applications is faster than a GTX 980 SLI setup.
Nvidia CEO Jen-Hsun Huang made at the unveiling of the new video cards in particular, much is known about the GTX 1080 . The cheaper GTX 1070 was announced shortly, but this video card are all published specifications. The Nvidia GeForce GTX 1080 is based on the GP104 GPU and has 7.2 billion transistors. There are 2560 cudacores present and the video card contains gddr5x 8GB memory Micron with an effective speed of 10GHz. The memory bus is 256-bit wide, which allows the memory bandwidth comes at 320Gbit / s.
With a base clock of 1607MHz and 1733MHz Boost clock of its particular clock speeds much higher than the current generation of GPUs. Moreover, Nvidia claims that overclocking is possible to 2GHz. Pascal GPU is made on a 16nm FinFET process-and is the successor to the Maxwell GPU, made at 28nm. The smaller is the new GPU process more efficient: the 1080 GTX has a TDP of 180 watts. That is more than the 165 watt of the GTX 980, but the new GTX 1080 must then also be much faster.
Nvidia has no benchmarks have shown, but claims that the GTX 1080 at Fri applications faster than the Titan X and that a SLI configuration of two GTX 980 cards can be defeated. At regular games such as Rise of the Tomb Raider and The Witcher 3, the 1080 GTX is about 1.7x faster than a single GTX 980, judging published on the Nvidia graphics. This new card will also be faster than the GTX 980 Ti.

The GeForce GTX 1070 includes a GP104-GPU Pascal generation, but the cheaper video card gets regular GDDR5 memory. Further information has not disclosed Nvidia, the manufacturer called a power of 6.5 TFLOPS, while it was higher in the 1080 GTX with 9 TFLOPS.
The GeForce GTX 1080 has three display port connectors that are certified to the 1.2 standard, but also support the 1.3- and 1.4 standards. That makes it possible to use 4K monitors with higher refresh rates such as 120Hz. These are not for sale yet, but will probably later come to market this year. According to Nvidia, it is possible to control a screen with a resolution of up to 7680×4320 pixels at 60 Hz, with RGB display on 8bit and use of two-port display cables. With a single DisplayPort 1.3 connector is the same resolution as possible on 8bit yuv420- subsampling. There is also a HDMI 2.0b port site, which 4K supports resolutions up to 60Hz.
It is possible to combine multiple GTX 1080 graphics cards in SLI setups. Before that Nvidia has designed a new SLI-bridge HB, which offers twice as high bandwidth as the SLI bridge Maxwell GPUs.

The 1080 GTX is available from 27th May. The “Founders Edition” will cost $ 699. Variants get a custom PCB according to Nvidia expected a price of $ 599. Prices are not yet published, but converted VAT-inclusive prices come off at 742 and 635 euros.
Probably said Founders Edition features the illustrated reference cooling coil, which should allow high overclocking speeds. According to Nvidia will ASUS, Colorful, EVGA, Gainward, Galaxy, Gigabyte, Innovision 3D, MSI, Palit, PNY, and Zotac issue such a card.
From June 10 will also be a “Founders Edition” GeForce GTX 1070 are available for $ 449. Variants with customized PCB will start at $ 379. Converted including VAT involves approximately 477 and 402 euros.
To demonstrate the performance of Pascal cards with VR applications, Nvidia has created a virtual reality experience: VR Funhouse . Nvidia also comes with Ansel , a new method to capture images in games and share. With Ansel can ingame pictures are made, various effects can be applied. Nvidia also claims that rendering screenshots ‘super-resolution’ of 4.5 giga pixels is possible. To use Ansel is the game there to offer support. Include The Division, The Witness, Unreal Tournament, The Witcher III lawbreakers and Paragorn get Ansel support.
In early April announced Nvidia Tesla all the P100, which uses a larger version of the Pascal GPU and hmb2 memory. The Tesla card is a so-called accelerator for high performance computing. This can be used in servers and super computers to perform gpgu calculations. The Tesla P100 features a GP100-GPU 15.3 billion transistors. The GP104 GPU’s where the new GeForce cards are based on, are a smaller version of this chip.
