[PCWorld]AMD shows off Vega's ability to handle 8K graphics at NAB - Page 4

post #31 of 68
if i remember right, pushing resolution is highly dependent on the ROP count right? 64ROP units confirmed?

also, which Vega is this? 11 or 10?
post #32 of 68
I ordered 1080Ti. I am done waiting for Vega. It's not going to be worth it anyway. It's going to be another Polaris. Especially compared to Volta.

Not only is it ridiculous from the point of view of human vision, it's ridiculous in terms of:

A) Not needing to see extra detail from people's nose hairs, wrinkles, and moles.

B) Ridiculous bandwidth requirements. Good luck watching even plain non-HD Netflix on capped broadband without paying ridiculous amounts. Where I live I have the choice between capped satellite and cellular. Don't ask how much 30 gigabytes per month costs, let alone the average of 60 we were using at our old place when we had cable. That was with very little Netflix, practically no HD Youtube, etc.

C) Ridiculous encoding times.

D) Ridiculous file sizes.

16K is needed for perfect VR because the screen is extremely close to the eyeballs. For television 8K is not needed. There are things that are needed, like wide color gamut, high contrast, lack of motion blur, perfect uniformity, low-as-possible input lag, lack of reflections, long phosphor life, high-quality audio, etc.

Shrinking OLED pixels for 8K is going to reduce lifespan even more, too. Corporations want everyone to be convinced that they need 8K because they've tried to speed up planned obsolescence with all this pixel-pushing — to hysterical levels. We had standard definition forever but, suddenly, we need a new television set every few years. Instead of just making HD 720 then 1440 we had the stupid 1080 standard, which had resolution that was too low. Now that we are getting 4K, which is more than enough for television and home film viewing, we're supposed to need double that. BS.

+ rep.

I agree with all of that. Tech companies want to keep pushing ever higher and higher resolutions for planned obsolescence and to keep fleecing us when it is a fact that the human eye can't define detail past 4K from general viewing distances.

What still shocks me is the amount of sub-1080p content on TV these days in the UK, So the marketing is telling us to buy 4K but content is still mostly not even HD where I live it's laughable.

8K should only be used in studios for film making, the source has to be better than the commercialized products.
with an 8K source, the film makers could simply downscale it to 4K for BD releases, or 1080P for TV streaming.

on the other hand 8K could be used in cinemas simply for it's wow factor.

People should just use the Blur Busters aliasing test to determine how much resolution they really need.
http://www.testufo.com/#test=aliasing-visibility
If you can see any aliasing on your monitor that means your eyes are resolving more detail than your monitor provides.

All of the classic visual acuity tests only account for part of your visual system.
http://www.michaelbach.de/ot/lum-hyperacuity/index.html
You can see up to 10x more detail than the technical limits of "visual acuity".


There certainly is a point of diminishing returns, but 4K isn't it, chances are 90% of people are going to be able to fully resolve high contrast detail on a 4K screen with the same field of view as what they're using now.
8K will be getting closer to the limits for a lot of people, but certainly not everyone and probably not even the majority.

If I'm going to have a monitor with enough pixel density to just barely eliminate "static" aliasing (not moving), it needs to be a 30" 8K monitor.

Really all the people who measure these things according to the minimum required resolution are doing it backwards, if you want "perfect" image quality then you want to be absolutely sure that your display is giving you more resolution than you can see.
I should be asking for a 27" 8K monitor.

As for movie applications, apparently IMAX Film is equivalent to 12K resolution (https://en.wikipedia.org/wiki/IMAX), and all you need to do in order to achieve the same field of view as an IMAX screen (according to the original specificatios: http://www.lfexaminer.com/20090522a.htm) is have the farthest viewing distance equal to the screen width, so if you have an 82" screen and you sit six feet away, you've got the same horizontal field of view as IMAX.

Bring on the 12K TV's.

And here I am, satisfied with 1440p, maybe 4k in a year or two. When hardware is actually capable of running it without me breaking the bank.

I've never seen an 8K screen but how much of an improvement could it be over 4K. Except for 60 inch plus.

depends on what you're expecting.


8K would look stunning with a proper 8K source though.
i mean an 8K camera that isn't simply interpolated, but a true 8K camera.

No, computers aren't entrenched in 4K. Most laptops ship with 1366x768 panels or 1080p. The ones that go above that are 1440p and utterly massive, or they're 2160p or 1800p with high-res scaling. It looks nice, but it isn't much better than 1080p or 900p as far as real estate goes.

Laptops are the worst case scenario for 4k adoption. tiny screens that are on a strict power budget. People on OCN are already whining about 27inch 4k screens. combined with the higher power draw from more pixels and you have a laptop reserved for the very top end.

Now that would be interesting. A Zen-based core complex, a Polaris 11-tier iGPU, and four of those dies on one chip? It'd be like Naples but with APUs.

Polaris 11 is the small GPU right? Because I dont think they are going to put a small GPU on this. An earlier article explored the possibilities of making a giant CPU + GPU chip in order to scale data gathering and processing. It was featured here on OCN ( technology section maybe ) but I can't find it now.

Full HD video has a resolution of about 2 megapixels per frame, 4K footage has a resolution of 8 megapixels per frame, and 8K will have a resolution of 32 megapixels per frame.

https://www.wired.com/2016/01/8k-tvs-coming-to-market/

8K is a 200% + jump in resolution..

That's why it's being marketed for professionals, not home users.

 

I could certainly do with an 8K display for photo work. Do I need it? Absolutely not. Would it be cool as hell to appreciate an image in its full detail without having to zoom in? Hell yes it would.

 

Hell I've been editing for a few years now on 1080p and it's done the job just fine. But you can never have too much resolution for these kind of things when the output from your camera is upwards of 30 megapixels in many cases (not mine, I shoot at 22mp)
