Official Vega Thread

Hello.

Looks like some of those features in Vega are enabled:

Vega beats even a 1080ti at 1080p and 1440p... and beats the 1080 at 4k. Heck even Vega 56 beats the 1080ti at 2k... and frametimes.

People are calling shens on the article due to the fact that Core0 bug is still present as well as the fact that the game is cap'd at 30 - 60FPS with Vsync enabled, they had to do a work around to get it up and running. 980Ti users can't even start the game and massive frametime issues. The FPS lock and Vsync forced on will be removed in a future patch.

Its a piss poor console port.

Well they did manage to remove fps caps for the review. Fps numbers are typical for modern racing games. Ill give nvidia a driver update for it but we may be seeing FP16 at work here.
 
Why would a game that is largely a console port have features enabled that other PC-first releases don’t have? Do you really think AMD would be silent about that too? They would have marketed it at least a little bit. They may not have a strong marketing team but they aren’t that bad.

It seems like the game is buggy but I hope you’re right and it’s a sign of things to come. Thus far I haven’t even looked at Vega as someone purchasing a card in two months. It’s just been disappointment after disappointment at the high-end.
 
High end is overpriced no matter what you buy.

To me this is a properly optimised amd title due to it being a console port but porting games from console isnt an issue like it used to be simply due to the fact that pc and consoles now use the same hw.

Nvidia said there was no issue with the game on their end. IMO it might not be using gameworks tho...

Nvidia confirms the backlog

The ranking in Forza 7 is very unusual. Nvidia has confirmed ComputerBase, however, that the results are so correct, so there is no problem with the system in the editorial regarding GeForce.

It is noticeable that the Nvidia graphics cards seem to be much earlier in a CPU limit than those of AMD: while for example the Radeon RX Vega 64 is synonymous in Full HD still good twelve percent faster than the Radeon RX Vega 56, is the Distance between the GeForce GTX 1080 and the GeForce GTX 1080 Ti only seven percent. And the GeForce GTX 1070 to Nvidia's flagship just 25 percent, in Ultra HD 39 percent - usually it is 60 percent.

All of this makes sense. Nvidia uses a software scheduler so itll hit the cpu limit sooner. The speed between Furyx and Vega also finally makes sense. Vega SHOULD be about 60% faster. And at the 2-3 months mark after vega being released games should start to work on a new architecture like vega better.

Monday should being new results tho so we'll see if they tested a buggy beta...
 
Not worried about price at the high-end. I’m concerned with what Vega offers performance wise against the 1080TI except for this one game it seems. I wouldn’t be surprised if a driver comes out that jumps performance for NV but we’ll see.

Price won’t be a concern when I get my rig back. I’m going ham city.
 
Well one has to keep in mind that pretty much every single console out there is packed with AMD CPU's and GPU's, be it all the variants of Xbox ( didn't know there were so many ), as well as the PS4 and all variants of it, look here and scroll down a bit:


https://www.gamespot.com/articles/console-specs-compared-xbox-one-x-ps4-pro-switch-a/1100-6443665/


Only the switch has any Nvidia designed hardware out of all of them, so is it so hard to believe that a console game may simply run better on AMD, since they pretty much have the console market locked up to themselves?
 
Believing that it runs better because of “features” enabled on Vega is a stretch since AMD would have marketed to boost sales. Also features that apparently just enable themselves without any driver update ..

It could very well run better on AMD. I’d wait to see if NV releases a driver update though.

Not so much specific features, but the overall layout of the architecture and using it's inherent strong points.....That alone could be enough.
 
Anyhow, even though I am disappointed that official multi GPU support gets knocked down to 2 way setups with Vega, so it's now even with what Nvidia has been doing ever since they introduced Pascal, and it's both due to relatively few users really going all out anymore GPU wise, and that developers also use effects that just don't scale well on 3 and 4 way setups from either company, so it isn't due to the design of the hardware and what they support well and not so well, the decision on my end still remains with team red.


Specifically for a pair of Vega Frontiers for their 16 GB of ram on board, and the means at the driver level to use HBCC........Basically reserving a set amount of system memory for the exclusive use of the GPU's and nothing else, and I do believe those 2 advantages will show themselves as games get even more demanding.......There's never been any point in PC history where end users have too much memory on board and it remains that way indefinitely.......Software eventually catches up.


Power and cooling are non issues with me having the hardware to keep 4 R290x's cool, which do use quite a lot of power and did run hot with their stock air coolers, running those at 100% load and only hitting 55*C so the frontiers will be water cooled as well with that same gear used to cool 4 cards, and I'll be running the Vega's at +50% power budget with the clocks set at 1700Mhz......Only the voltages for the GPU and memory remain at stock.....Doesn't seem to make a difference on overclocks.



With 2400 watts on tap, I don't expect the cards to ever need to throttle down from either temperatures or lack of power, and it'll be pretty much the best case scenario we'll ever see 2 Frontiers in multi GPU operate under, unless someone else goes for even more extreme cooling.
 
Good news on the cpu side of things too:

Hi all,
Just following up here, regarding the "one core" issue that made the rounds yesterday. There's been an update to that WCCFTech story with some further clarification from our chief software architect, Chris Tector. Here's the quote:

"Forza Motorsport 7 is not limited to running on one core. There seems to have been a miscommunication along the way. Forza Motorsport 7 uses as many cores as are available on whatever system it runs on, whether that is a 4- to 16-core PC or the 7 cores available on Xbox One.”
Thanks,
Brian
 
7700x users will automatically dismiss the game if it really does use as many cores as you can throw at it, and it no longer is the fastest option out there.

that maybe why nv cards are slower also

wasn't there something about nvidia drivers not using lots of threads ?
or was that just on ryzen

Since all we have is the developer saying that the game will use as many cores / threads as there are available and not all of them are dedicated to just graphics obviously, i doubt that's the case.
 
The game does not seem to be a cpu hog, a stock 2600k had no problems running it at 60fps in the demo, y'all need to remember that it is a game that runs at 60 fps on the xbox one too.

As i had mentioned earlier though, all the X box versions out there and the same goes for the PS4, have AMD 8 core CPU's and AMD GPU hardware as well, and only the switch has an ARM processor and Nvidia GPU, so it may be the case that while the game will run on anything as it should, there's an inherent advantage for AMD no matter how many driver tweaks Nvidia does.



There are games out there that do the exact same thing for Nvidia, running better on their hardware than on AMD's and unless i'm mistaken, Grand theft auto V is one of them.......It'll always run better on Nvidia than it will on AMD hardware, no matter how many software tweaks are done at the driver level.


Some games are simply coded to benefit from the strong points of a given architecture, even if they can run on anything......

Hahahahaha

In my case I had nothing but trouble with my 970 and a long run of nvidia drivers. Pissed me off so much that i bought a RX 580. I went from a stuttering shitpile mess with missing level geometry and streaming issues on even the lowest settings to running it over 80 fps on a mix of very high and ultra settings.

In my case that's a load of wank.
 
Anyhow, that particular Forza 7 example in terms of results, was run in DX12 mode with 8X MSAA enabled in 1080p / 1440p and 4K, but now there's also this though no particular game is mentioned and both Vega and Pascal are using the latest drivers:


AMD's new Radeon RX Vega 64 can beat NVIDIA's best GeForce GTX 1080 Ti in some scenarios, where in multi-GPU configurations the RX Vega 64 begins competing against the GTX 1080 Ti in 8K... and now the same can be said for DX12 and Forza 7.

2 card setups sees Vega becoming more competitive with a pair of GTX1080TI's, and it's just been released and only running the 3rd official set of drivers for it.....This could be interesting in a few months if this tendency maintains itself....:evil:

8K is a brutal load without a doubt.
