Will get an RX480 after reviews come in - want a great AIB (probably ASUS).
it's going to come down entirely to efficiency improvements in the memory subsystem, IMO. It's only got 2/3s the bandwidth of the 390, and looking at the comparitive performance of the 290 and 390 memory bandwidth did play a part in that - the 390 had around 5% clock increase but benchmarked around 10% higher, suggesting the 20% boost in memory bandwidth it received did play a part in the performance improvements. Unless they've done a lot of work on memory compression I think there's a real risk the RX 480 will choke on its reduced bandwidth...Originally Posted by malfunction
As to the actual QOTW - I can't see me ever spending more than £100 on a GPU again, given the amount of raw power available now, so I personally don't need it to be any particular speed. If it is around the same speed as an R9 390, and if you can buy one in the UK for £165 at or near launch, I think it'll very quickly become the recommended card in a mid-priced gaming rig. What is interesting is to know the launch price before we get performance leaks: we know which card it's replacing in the market segment, so we can speculate about what performance we'll get in that segment (usually we get the performance leaks then speculate about pricing). According to http://www.anandtech.com/bench/product/1592?vs=1594 the 390 is roughly 50% faster in games than the 380X, so there's a big performance gap in the segmentation as it stands. However I get the feeling that if it falls more than, say, 10% short of the 390 people will be sharpening the knives for AMD again. We know it's got the front end to get close to the 390: it'll be interesting to see how much that narrow back-end holds it back...
In order to buy one, I guess is the question..
At that price range (£165 in the UK from decent retailers) I'd have the option of more frequent GPU upgrades, compared to £250 and upgrading less often, so I can tolerate a smaller increase in performance at each step as I only need to be able to play today's/next few years games at preferred settings.
The last card I bought, 7870, is only showing its age in the very most recent titles, and even then not at any cost to the gameplay of said titles - I'd like to have a bit more umph for the witcher 3.. and that's I think about it. Is there anything coming up on the horizon that'd make me wish for more? I'm drawing a bit of a blank - star citizen *if* the retail price policy is reasonable, but spec'ing for that now is a fools errand!
Apart from games? VR is too new for me yet, but a monitor upgrade might be a possibility - 1440p and some form of adaptive sync or just high refresh rate, which would certainly call for an upgrade over the 7870. In such cases more frequent replacement of GPU is likely to be handy as new tech improves with new standards.
So I guess my criteria is 'few (say 2.5) years before replacement', 1440p target resolution, 45+fps target framerate in games like TW3.
Which gives me the answer of something around the 390X/980 level (and going by the Hexus chart, they fall together so a 3dmark score of about 11,450

The 380 had a lot of memory compression work on it, the 390 has more than twice the memory bandwidth of the 380X.
AMD seems to pitching the RX 480 to the VR/1080p/1440p market rather than 4K, so I imagine it's just a question of what visual output you are going for and what ball-park fps too. The TDP is pretty appealing compared to the R9 200/300 series too.
I'm thinking most likely the performance will be between the 970-980 and if it launches under £180 it will be the card to have for most gamers I think.
I think at this point, all I want it to do is have decent Linux drivers
Should hopefully be in place, in terms of working at least if not stellar performance.I think at this point, all I want it to do is have decent Linux drivers
Currently using the open source drivers on my R9 380, works well enough for my Steam game collection and seems to be improving in performance all the time. Might try the Crimson drivers again to see if I can get Vulkan working as I haven't played the Talos Principle expansion yet and it would be nice to try that in the new renderer.
Polaris patches for the graphics drivers have been going in for some time though, might be working before GTX9x0 open source drivers at this rate.
If the card costs around £165 and drops between the R9 380X and R9 390 in DX11 then thats a tempting prospect. A lot hangs on Vulkan and even more importantly DX12 performance. This could be the first fully DX12 compatible card.
What do you mean by fully DX12 compatible? It almost certainly won't support all of the possible DX12 methods, for eg. I would be surprised if it supported Conservative Raster or Raster Ordered Views.
Pretty much what I said. Fully DX12 compatible as opposed to not fully compatible.
Ah OK, well we've already got cards out that are fully DX12 compatible.
We have lots of non DX12 compatible cards. It's crazy to have a non standard standard. But at £165 I suppose thats too much to ask.
I expect rx480 to match 390, no more though.
Almost every card released in the last few years is 100% compatible. They don't necessarily support the optional features like raster ordered views, but no card does support all the optional.
You mean every card released in the last few years, some are almost 100% compatible?

I think Intel is closest to 100% DX12 support ironically enough!!
