I don't think the 3080 has enough Vram

    3080 with 1 gb vram would easily beat titan rtx and radeon vii. Ram does nothing if not needed. Move on.
     
  2. RAM does nothing if not needed.... hmm.... but it's always needed? So I don't follow...framebuffers for one but that's beside the point (small amount in larger scheme) - & why move on? You're always really laid back...

    I can't stand childish moments and situations everywhere around. I believe the myth of more ram the better stopped 10+ years ago. Now it is pushed on consoles and gpus. People should really further educate themselves during their lifespan. Science is not about psychology but also proof!!!

    This ram/vram thing is built upon fake future-proofing and the safety of customers' conscience or battle of fears. Other mindsets are laid back, not mine. I am open minded to understand how the hell, even you, enthusiasts connected stuttering and lagging with amount of "ram". Proofs please.

    Do not trigger their fears. Like those who OC even 1mhz and try to find corrupted textures or artifacts, just to face their anxiety. Of-course GB equals years. Any gpu with more than 8 gb vram adds years of gaming! For example, 3090 will easily play all games until 24-8=16 years, or 2036! :eek:

    But 3080 should also offer smooth gaming for only 2 years from today. 2022 is so close to change that gpu. Bad investment.

  5. Don’t put words in my mouth that were never there. Hey please calm down we don’t have beef lol I am just trying to understand you but you haven’t provided any “science” just described the extent of your frustration. What “proof”? What is this proof you speak of? I am asking for you to explain in detail from a functional, mechanical standpoint that which you are so adamant and intent on countermanding. Be specific. Educate me...

    Educating takes effort. Thats why insults are usually the response. Humanity has all but lost the ability to share a different opinion and still converse about it. Scary times.

    Q: Why only 10 GB of memory for RTX 3080? How was that determined to be a sufficient number, when it is stagnant from the previous generation?

    We’re constantly analyzing memory requirements of the latest games and regularly review with game developers to understand their memory needs for current and upcoming games. The goal of 3080 is to give you great performance at up to 4k resolution with all the settings maxed out at the best possible price. In order to do this, you need a very powerful GPU with high speed memory and enough memory to meet the needs of the games. A few examples - if you look at Shadow of the Tomb Raider, Assassin’s Creed Odyssey, Metro Exodus, Wolfenstein Youngblood, Gears of War 5, Borderlands 3 and Red Dead Redemption 2 running on a 3080 at 4k with Max settings (including any applicable high res texture packs) and RTX On, when the game supports it, you get in the range of 60-100fps and use anywhere from 4GB to 6GB of memory. Extra memory is always nice to have but it would increase the price of the graphics card, so we need to find the right balance.

    Also according to Nvidia, their memory compression is really good. It's possible that 10 GB is equivalent to much more compared to previous generations. No idea if any figures are out there on that, I've only seen fancy looking double helix looking graphs.
     
  10. Thank you; I did not know this. That is interesting.
    Appreciate the post Amaze & link

    As per usual it's just BS coming out of nvidia's mouth. Shadow of the tomb raider with rtx on and full ultra settings at 4k uses up to 9 gb vram, and rise of the tomb raider with full ultra settings uses up to 11gb vram.

    They know it will be an issue and try to downplay it, and in this case outright lie about it.

    For playing games maxed out at 4k, 10gb is borderline enough right now... in 2 years? It certainly wont be...

    What we need is a Turing vs Ampere vram usage comparison article /video, perhaps the numbers will be worth talking about?
    We should hit Hilbert up for this in his Review.

    if only you knew what measurements you were actually looking at.

    That guy is the worst troubleshooter in the history. 15 second regular stutter could be bloody anything EXCEPT that which he think that it is - ie running out of VRAM.

    I installed COD Warzone, enabled Ray Tracing, AB shows 7 something gigs of VRAM and my FPS is a flat line.

    ITT: Folks that don't know what VRAM allocation is.

    Post #2 answered this already.

    The fact that his FPS is still pretty high show he's not crippled by VRAM, once you hit that limit your frames tank. Stutter can be caused by anything from drivers, software, hardware, etc.

    and that is 100% a damn lie. test it for yourself instead of being stupid enough to believe those game only use 4-6 gb of vram. FFS Wolfenstein Youngblood not just uses but actually REQUIRES more than 8 gb at just 1440p if running max settings with RT on. you flat out get a warning and the game will hitch and then literally lock up. you have to reduce texture streaming down one notch and lower DLSS quality to avoid the issue. and EVERY one of those other games use well over 6 gb of vram at 4k and most will exceed 8gb easily.

    and what the hell does that even mean? the nvidia quote said all those games only use between 4-6 gb at 4k maxed which is complete BS. Dragam1337 simply showed a screenshot of one those showing over 9 gb of vram usage in game that nvidia claimed only uses 4 to 6. hell I could provide you screenshots for every game listed using well over 6 and most pegging my 8gb of vram. when I had my 1080 ti I saw several games use way over 8 gb and some even use over 10 gb maxed at 4k. and yes I know using is not the same as requiring but the nvidia quote mentions "using". and as I just said there is Wolfenstein Youngblood that REQUIRES more than 8 gb at 1440p fully maxed with RT on and DLSS on quality so the nvidia guy is a liar.

    Allocated memory and then actual GPU memory usage and the difference between the two. :)
    Could be half that amount or even a quarter of it meaning there's plenty of VRAM to spare still.
    (EDIT: Changed the initial text a bit. I'm really bad at explanations but yeah.)

    I do hit close to full VRAM utilization in Monster Hunter World though but that's due to how that game uses memory and the texture pack which goes from rough to really good but more than doubles VRAM requirements and once that's out the game quickly crashes. (It can over allocate but then it's stuttering and all sorts of issues for D3D11)

    EDIT:
    https://www.resetera.com/threads/vram-in-2020-2024-why-10gb-is-enough.280976/

    Just going to use this image for this because I'm not that great at explaining.
    (The full write up is also quite good for a more in-depth explanation.)

    (I really don't do explanations very well but this should work.)

    Bingo, most apps are reading a value equivalent to GPU Commit not Gpu Dedicated

    MHW is an extreme edge case, it actually over commits the vram and then proceeds to use it as a scratch pad instead of swapping dedicated memory back and forth depending on use.

    no it doesn't.
