Looking at the RX480 as the next card for my 17 YO and the XFX OC seems pretty good ... albeit it is using the reference cooler.

When do the aftermarket coolers get released guys?

He has a GTX760OC at present ... so hoping the RX480 is a good upgrade for the price. They are about $440 AU here for the 8GB model ... I just don't like the clunky cooler.

This lad seems to know what he is doing ... so you can get some idea of the upper limit of the card too.

Depends on where you live perhaps, but this week. Maybe even today for a couple of vendors.
 
Okay so I just tried Doom out with the Vulkan API enabled on my R9 380X rig. Played about 20 minutes on the Foundry level as that always seems to give the largest frame drops.

I set everything to Ultra with resolution at 1080p, AA = TSSAA X 8.

Graphics card was at factory settings, 1040MHz core and 6000MHz vram.

All I can say is WOW.....

Frame rates seemed to be hovering around the 90 mark most of the time.

At worst I saw it dip to 62 fps during a particularly heavy battle while looking towards the far end of the foundry (so draw distance was close to maximum and the molten metal streams were visible - this always made my fps tank before).
But that was rare - it tends to go no lower than the 70's with Vulkan for the rest of the map when it does dip.
Like I said earlier, it spends most of the time near 90. Some parts of the map can see it hit well over 100.

The monitor is 60Hz for my R9 380X rig so I finally set the fps to 60 and played a few minutes.... with a rock solid 60 fps and perfect frame times it felt fantastic.

All I can say is Vulkan rules!
 


AMD worked with DICE to get Mantle support in Battlefield 4. Since Vulkan is built with significant portions of Mantle in it, they really ought to be able to add Vulkan support to the Frostbite engine at some point. But there's no guarantee, maybe Microsoft will offer them a better deal focusing on DX12.

BF4 actually tends to run a little better on newer Nvidia cards than on competing AMD cards, by the way. So I wouldn't really call it AMD sponsored beyond the Mantle thing (and the bundle deals they did back in the day).
 


Do you have the full ins and out of every and any deal or agreement between AMD and DICE? If so please share so that the rest of us can decide whether BF4 is actually sponsored by AMD or not.
 


No. I specifically explained the background for why I wouldn't really call it sponsored by AMD at this point (with the implication of special sauce to run better with their hardware).
 


But it doesn't matter what (you) some random wants to call it if it's sponsored by AMD then it's sponsored by AMD, end.



Yeah, I've always wondered why that somehow makes it "not a fact"! :lol:
 


And always has been, on it's release Mantle was the "big thing" and BF4 was the showcase.
 




You didn't say that, from your post it's like you didn't know.
 


Will you stop trolling? Go back and read my posts. I specifically stated AMD worked with DICE to get Mantle support in BF4.
 
seems the 490 card model keeps popping up here and there. still pointing toward a dual 480 card according to those who like to guess on this sort of thing
http://wccftech.com/amd-rx-490-mystery-4k-gaming-gpu-listed-sapphire/

i still think it's a viable option, especially with MS adding a new multi-gpu, easy to use, layer to dc 12 recently http://hexus.net/tech/news/software/94249-microsoft-makes-multi-gpu-support-easier-dx12-devs/
 
I watched a video on Youtube (AdoredTV or RedGamingTech) where it was speculated that it might be a dual GPU card based on the RX 480's Polaris 10, but would be configured in such a way as to work with some sort of hardware scheduler chip, effectively doing away with the need for Crossfire and it's problems as the card would appear to the system as a single GPU. A bit like a dual core CPU.

It's all speculation as a guy from AMD who was being interviewed was asked if the RX 490 would ever be released and a 'no comment' was the response!
 
I don't think a dual 480 would be competitive on price enough against a 1070 (unless DX12 makes it amazing but it would be to early on release to do well based on this) so contrary to most rumours out there I am guessing its a dual 470 or an early vega without HBM. This is totally my personal guesstimate and I accept its likely wrong.
The whole GTX1060 6Gb & 3gb being totally different cards is making me wander if there is some truth in the rumour about the next to release will never be a real card at retail, or at least its a stupid idea to confuse consumers. Its not like they are running out of numbers between 1000 & 1070.
 
it would compete with a 1080 not a 1070. it's being suggested as a 4k card and 1070 is not a 4k card.

at $500-550 reference prices it would be an awesome deal vs a 1080 even it does not match it 100% $600 or so for custom cards would be pretty ideal to me.
 
The only interesting bit from that leak/rumor posted in WTFBBQTech is the transistor count. It said "up to 18B". That is, if close enough to that number, twice the transistors the Fury has. We can start speculating on where it will land based on that with estimates of clock speed around 1.1/1.2Ghz base/turbo.

So, on a very superficial analysis, I would say it will put it just above the 1080, if not on par. If they manage to squeeze a bit more speed (Hz) out of it, it might put it ahead constantly. From what I remember, AMD's transistor count (translated into CUs), don't scale linearly, so 3X the amount should be 2.5X the RX480 (if not a tad less).

Please feel free to challenge/destroy this napkin estimate 😛

Cheers!
 


Another preconceived misconception. 😀



I see two things knobbling that sketch, power requirement and heat management.
