NVIDIA Announces the GeForce RTX 20 Series: RTX 2080 Ti & 2080 on Sept. 20th, RTX 2070 in October

NVIDIA's Gamescom 2018 keynote just wrapped up, and as many have been expecting since it was announced last month, NVIDIA is getting ready to launch their next generation of GeForce hardware. Announced at the event and going on sale starting September 20th is NVIDIA's GeForce RTX 20 series, which is succeeding the current Pascal-powered GeForce GTX 10 series. Based on NVIDIA's new Turing GPU architecture and built on TSMC's 12nm "FFN" process, NVIDIA has lofty goals, looking to drive an entire paradigm shift in how games are rendered and how PC video cards are evaluated. CEO Jensen Huang has called Turing NVIDIA's most important GPU architecture since 2006's Tesla GPU architecture (G80 GPU), and from a features standpoint it's clear that he's not overstating matters.

[...] So what does Turing bring to the table? The marquee feature across the board is hybrid rendering, which combines ray tracing with traditional rasterization to exploit the strengths of both technologies. This announcement is essentially a continuation of NVIDIA's RTX announcement from earlier this year, so if you thought that announcement was a little sparse, well then here is the rest of the story.

The big change here is that NVIDIA is going to be including even more ray tracing hardware with Turing in order to offer faster and more efficient hardware ray tracing acceleration. New to the Turing architecture is what NVIDIA is calling an RT core, the underpinnings of which we aren't fully informed on at this time, but serve as dedicated ray tracing processors. These processor blocks accelerate both ray-triangle intersection checks and bounding volume hierarchy (BVH) manipulation, the latter being a very popular data structure for storing objects for ray tracing.

NVIDIA is stating that the fastest GeForce RTX part can cast 10 Billion (Giga) rays per second, which compared to the unaccelerated Pascal is a 25x improvement in ray tracing performance.

Nvidia has confirmed that the machine learning capabilities (tensor cores) of the GPU will used to smooth out problems with ray-tracing. Real-time AI denoising (4m17s) will be used to reduce the amount of samples per pixel needed to achieve photorealism.

    Nope, it's over:

    Cryptocurrency miners' demand for Nvidia computer chips evaporates [latimes.com]

    Nvidia Corp.’s nine-month crypto gold rush is over.

    Sales of graphics chips to miners of cryptocurrencies such as ethereum dried up faster than expected, the Santa Clara company said. For a second quarter in a row, investors ignored Nvidia’s growth in its main markets and ditched the stock.

    Nvidia’s stock fell 4.9% to $244.82 a share Friday.

    “Our core platforms exceeded our expectations, even as crypto largely disappeared,” founder and Chief Executive Jensen Huang said Thursday on a conference call. “We’re projecting no cryptomining going forward.”

    [...] Nvidia said it had expected about $100 million in sales of chips bought by currency miners in the fiscal second quarter. Instead, the total was $18 million in the period, and that revenue is likely to disappear entirely in future quarters, the company said.

    Investors are expressing their concern at the sudden collapse of what had looked like a billion-dollar business. Three months ago, Nvidia said it generated $289 million in sales from cryptocurrency miners, but warned that demand was declining rapidly and might fall by as much as two-thirds. Even that prediction was too optimistic.

    And yet the card is priced and specs for crypto mining & HPC.

      HPC != cryptomining, and they're priced high because Nvidia effectively has no real competition from AMD right now [extremetech.com]. They also want to make sure they get rid of existing GeForce 10 inventory. The prices will get cut in a few months or when AMD launches new GPUs, as is typical.

        AMD won't have anything new out until probably near the end of Q1 or beginning of Q2 next year. Even then, I'd bet what they release won't be able to compete with the high-end NV cards.

          That's what Intel said ...

            AMD diverted resources from Vega to Ryzen. They are such a small scale company that they couldn't seem to do both properly. However, the cryptomining boom created such demand for GPUs that they managed to do OK with Vega. The head of AMD's graphics division Raja Koduri left because of this and other issues, and is now at Intel helping them get back into the discrete graphics market with a 2020 GPU release.

            AMD
            Revenue: $5.33 billion (2017)
            Net income: $43 million (2017)

            Nvidia
            Revenue: $9.714 billion (2017)
            Net income: $3.047 billion (2017)

            Intel
            Revenue: $62.76 billion (2017)
            Net income: $9.601 billion (2017)

            It's AMDavid vs. 2 Goliaths. In order to damage one, AMD had to ignore the other. Soon, AMD may be challenged on discrete GPUs by both Intel and Nvidia, while also being challenged by Intel on integrated graphics and x86 CPUs. Intel did use AMD integrated graphics on some recent chips, but that could be a temporary ploy to combat laptops with Nvidia discrete cards.

    Oh, thanks God for that.
