    Thats the only thing AMD can do to fight nvidia, reducing prices. Navi will probably do what Polaris did two years ago, reclaim the midrange to high end for AMD again.

    ^^ Yo, im waiting till Arturus (next Big Chip)
    I have a lot of headroom on my Vega, so VII is not mandatory update for me ;)

    1760-1800MHz is doable on my GPU.
    Already ppl are posting (on OCnet) 29k GPU scores with LC.

    Most of us are not interensted in a next big chip but upcoming great performing midrange gpus. If Navi can pull 2070 performance at 300$ it will be a killer card.

    First they need to replace Polaris then Vega.

    Yup, it's true.
    Mid range is Main 'Vein' for industry.
    Priced right with right performance can benefit all of Us (e.g. Beautiful & well optimised games).

    Wouldn't that be great... If only AMD had a 2080 performing card for $200 cheaper than the 2080. Why does anyone even think that AMD is going to undercut Nvidia?

    Seeing the market data showing the slow adoptance of RTX, and the reaction to the VII pricing, I think AMD will see that the market really isn't ready to bear those kind of pricings if they expect to move volume.

    AMD Navi GPUs might use Variable Rate Shading tech

    A patent filing by AMD has recently surfaced, indicating the chip designer's intent to use Variable Rate Shading (VRS) technology to speed up output from future GPUs.
    The patent was originally filed back in 2017 and explores VRS being used by next-gen GPUs. At that time, the furthest ahead the AMD GPU roadmap went is to the Navi GPU, offering "scalability and next-gen memory".
    Note that Nvidia has already implemented VRS to work with its Turing GPUs, and you can read more about that on page 6 of the HEXUS Editor's examination of the Turing architecture.

    [​IMG]

    A big clue to the attraction of VRS lies within its name. Its applicability is most relevant to VR headset rendering where the centre of the displays can offer the sharpest detail with lower fidelity required towards the edges and corners of the HMD displays.
    As the HEXUS article discussed, there are various other ways to apply VRS, such as Content- and Motion-Adaptive Shading so it can be more useful to use in gaming using a traditional monitor, for example.

    [​IMG]

    It certainly isn't set in stone that VRS is coming to AMD Navi GPUs, and AMD hasn't publically indicated it will.
    However, it would be a logical move to 'keep up with the Joneses' and make more efficient use of AMD GPUs in PCs and consoles.
    Furthermore, VRS is particularly useful in VR display rendering in HMDs which are expected to continue to progress and grow in popularity for PC and console users.

    In simple terms, VRS will apply full details on sections of the frames where most of the attention is focused while reducing the rendering load on other parts, thus increasing overall performance.
    This method specifically helps when running games at higher resolutions. Following are some of the benefits of VRS:

    Benefits of Apply Variable Rate Shading
    • Variable Rate Shading is a new rendering technique enabled by Turing GPUs. It increases rendering performance by applying full GPU shading horsepower to detailed areas of the scene, and less GPU horsepower to less detailed areas.
    • Variable Rate Shading works by varying the number of pixels that can be processed by a single pixel shader operation. Single pixel shading operations can now be applied to a block of pixels, allowing applications to effectively vary the shading rate in different areas of the screen.
    • Variable Rate Shading can be used to render more efficiently in VR by rendering to a surface that more closely approximates the lens corrected image that is output to the headset display. This avoids rendering many pixels that would be discarded before the image is output to the VR headset.
    • Coupled with eye tracking, Variable Rate Shading can be applied to maximize quality in the foveated area where the eye is directly looking and reduce the shading rate in the periphery. This method can improve rendering performance without noticeably impacting image quality.

    AMD Stands for Open SMAA and TAA Solutions

    A report via PCGamesN places AMD's stance on NVIDIA's DLSS as a rather decided one: the company stands for further development of SMAA (Enhanced Subpixel Morphological Antialiasing) and TAA (Temporal Antialising) solutions on current, open frameworks,
    which, according to AMD's director of marketing,
    Sasa Marinkovic,
    "(...) are going to be widely implemented in today's games, and that run exceptionally well on Radeon VII", instead of investing in yet another proprietary solution.
    While AMD pointed out that DLSS' market penetration was a low one, that's not the main issue of contention.
    In fact, AMD decides to go head-on against NVIDIA's own technical presentations, comparing DLSS' image quality and performance benefits against a native-resolution, TAA-enhanced image - they say that SMAA and TAA can work equally as well without
    "the image artefacts caused by the upscaling and harsh sharpening of DLSS."


    Of course, AMD may only be speaking from the point of view of a competitor that has no competing solution.
    However, company representatives said that they could, in theory, develop something along the lines of DLSS via a GPGPU framework - a task for which AMD's architectures are usually extremely well-suited.
    But AMD seems to take the eyes of its DLSS-defusing moves, however, as AMD's Nish Neelalojanan, a Gaming division exec, talks about potential DLSS-like implementations across

    "Some of the other broader available frameworks, like WindowsML and DirectML", and that these are "something we [AMD] are actively looking at optimizing…
    At some of the previous shows we've shown some of the upscaling, some of the filters available with WindowsML, running really well with some of our Radeon cards."
    So whether it's an actual image-quality philosophy, or just a competing technology's TTM (time to market) one, only AMD knows.

    Improvements upon SMAA would be interesting, a return for SMAA 2x and 4x would be nice to see though MSAA is kinda disappearing in favor of TAA though temporal AA using data from previous frames also causes a bit of blur even if image stability is good and aliasing particularly of objects in motion is greatly lessened.

    Hmm wonder if super sampling temporal anti-aliasing could be more developed to maybe counter it a bit though at a larger performance hit albeit less than full render super-sampling and having the entire image going through DSR/VSR or similar will be interesting to hear more about this and what else AMD (And NVIDIA.) are planning for 2019 and beyond. :)

    SMAAT 2x or SMAA 4x like in Sot Tomb Raider.
    SMAATx2 is enough for 1440p gaming IMO, not so taxing on Vega.... not blurry and no jaggies.

    That monitor looks amazing. I really like the projected light on the back. I assume this is like the Sphere Lighting thing where it takes the overall hue of the screen and projects it behind for increased room atmosphere.

    LC27HG70QQMXZN this have HDR600 & FreeSync 2 LFC
    it's upgrade for this model -> LC27HG70QQNXZA (it's HDR400, FreeSync 1)

    MXZN is step Up from NXZN (both shoud be at 425-500€ bracket)

    Rumored AMD Navi Radeon RX GPU “66AF:F1” Benchmarks Leak Out – Faster in Graphics Throughput, Slightly Behind in Compute Workloads

    AMD Navi GPUs are launching this year (7.7.2019) but we haven’t really got any information on how they would perform and what the specifications would look like until now.
    Over at CompuBench, we might have our first listing of an AMD Navi “Radeon RX” part which delivers interesting results.The listing at CompuBench was revealed by Dylan522p over at the r/hardware subreddit.

    The site lists down the specifications and performance metrics of a device codenamed “66AF: F1” and from the first impression, this seems like a next-gen part based on the Navi GPU as this specific device id hasn’t appeared before.
    Now one thing to note is that this device may be based on the Navi GPU architecture or something entirely different hence I am treating this information as a rumor but the results are very interesting so let’s take a look.

    The purported AMD Navi GPU comes with 20 CUs which would amount to 1280 Stream processors. Now, this would be true if AMD keeps their CU design similar with 64 shaders per CU and the GPU is, in fact, featuring 20 CUs since CompuBench does has a habit of reporting the compute unit count incorrectly.

    When it comes to performance numbers, we first have to take a look at whether we are comparing the various devices in the same OS and API as CompuBench can yield variable results when users run different OS/API.
    A device running in Windows/DirectX API would be much faster than a device running in OSX and using either OpenCL or Vulkan APIs.
    When it comes to performance results, the first tests are pure graphics where the rumored AMD Navi GPU posts much higher results and performance numbers compared to the Radeon RX 580. This almost matches the AMD Radeon RX Vega 56 territory.

    In compute benchmarks, however, the card is almost similar to the Radeon RX 580 which is what we had also been expecting since AMD Navi GPUs was tailormade for maximum graphics and gaming performance rather than compute horsepower.
    The deals with Microsoft and Sony for their next-generation consoles made that much very clear. So it’s easy to tell that the desktop PC and notebooks parts would be getting a similar treatment.
