Pascal Titan X Vs the Gtx 1080 First Benchmarks Revealed
Nvidia Reveals Pascal: GTX 1080 And 1070 To Trounce Titan Ten, GDDR5X Debuts
Nvidia has finally revealed the details of its highly anticipated next-generation graphics GPUs. Nvidia CEO Jen-Hsun Huang first revealed the roadmap for Pascal in March of 2014. It's been a long wait, merely based on what we learned tonight, it looks similar the wait was worth it.
Two high-finish graphics cards will be aircraft in the next few weeks: The GTX 1070, which will supervene upon Nvidia's toll to performance value leader, the GTX 970; and the GTX 1080, which takes the place of the very capable GTX 980, while simultaneously dethroning the company'southward flagship Titan Ten as the fastest GPU the company has ever launched. Both cards promise meaning functioning increases over their predecessors, while cartoon less ability than the already power-efficient Maxwell GPUs.
GTX 1080 And GTX 1070
The star of the evidence is Nvidia's GTX 1080, which features 7.2 billion transistors and 2560 CUDA cores operating at an unbelievable 2.1 GHz. Nvidia said the card delivers 9 TFlops of rendering performance. The GTX 1080 is Nvidia's commencement graphics processor to utilise TSMC's 16nm FinFET process node. The smaller process node is a cardinal chemical element to Pascal's ability efficiency, just Jen-Hsun Huang, Nvidia's CEO, said there were thousands of improvements and innovations, and billions of dollars in research and development that went into designing Pascal.
Nvidia said that the GTX 1080 offers two times the performance of the company's current flagship Titan X, while delivering three times the ability efficiency. AMD volition likewise exist moving to a smaller FinFET node process for its upcoming Polaris GPUs later this summer, but information technology will be moving to GlobalFoundaries' fifty-fifty smaller 14nm procedure. Nosotros're eager to compare the ability efficiency of the 2 products in the coming months, merely Nvidia has certainly fix the bar loftier with Pascal.
Huang as well announced the GTX 1070, which also offers staggering performance. Nvidia did not reveal the number of CUDA cores or transistors that make upward the GPU in the 1070, but Huang said the card offers 6.five TFLOPS of floating bespeak performance, and that this bill of fare volition outperform a Titan X, every bit well.
GDDR5X
Last year, AMD launched its R9 Fury series featuring Fiji GPUs, which featured HBM memory with much higher memory bandwidth than traditional GDDR5. Nvidia chose to skip the first generation of HBM memory, but the roadmap it shared at GTC 2015 indicated that we would encounter 3D retentivity on Pascal. We somewhat expected to see HBM2 paired with these upcoming cards, but neither of them feature this advanced retentiveness engineering. Nosotros volition likely even so run across HBM2 memory paired with a Pascal architecture GPU, but we may be waiting some time for that.
GDDR5X is the side by side fastest retentiveness available compared to HBM; Micron revealed GDDR5X in September 2015. The company told us that GDDR5X offers significant performance increases by doubling the retention prefetch size. Micron said that initial GDDR5X yields would offer speeds of at least 10 Gbps. Nvidia said that the GTX 1080 is equipped with 8GB of GDDR5X retention, but it did not mention the frequency at which it operates. The GTX 1070 is also equipped with 8GB of memory, just it'south non using GDDR5X. Nvidia chose to use traditional GDDR5 with the lower-finish card.
Simultaneous Multi-Projection Pipeline
Nvidia said that part of the magic behind Pascal's rendering performance is a new technology called the Simultaneous Multi-Projection Pipeline. Nvidia explained that traditional rendering techniques use one single-view port to to output to displays. This works merely fine with a single display, but we've seen a rapid change in display engineering, from multi-screen setups to ultrawide displays and at present VR HMDs with dual displays that crave warping and unique rendering techniques.
The traditional rendering methods don't play well with multiple displays. You generally see warping on peripheral monitors in surround setups, and warping an image for a VR display wastes performance by rendering parts of the image that are never seen. This allows the company to dedicate a properly proportioned scene to each brandish in a environment organization. Huang said this was previously possible only if you lot had a GPU for each display in your system.
For VR rendering, Nvidia takes this idea even further. It dedicates 4 view ports per center for an HMD and prewarps the image before striking the lenses. The end issue is a clearer paradigm with more authentic proportions. Nvidia calls this Lens Matched Shading.

The GTX 1070 will launch on June 10. The standard carte du jour will sell for $379, and the Founder Edition volition be available for $449.
