GPU Upgrade + DX12

linwelin · 28 Aug 2014 at 16:20

Have a question i hope someone can answer. If i was to buy a new GPU say a 270, will that support DX12 and all its new features when DX12 is released ? or would you have to buy again after DX12 is released to have all the new features, what ever they may be.

Not fully. For full DX12, you will have to wait for the new cards.

Ok thanks.

AMD say all GCN GPU's will support DirectX 12.

Support DX12 yes but will miss out on features that are part of DX12 and the OP asked for full support.

Interested in seeing if that is true. How do you know this? Any links?

Its about the same as a 670 that card the 285 by lookin at specs.

Gregster, the amd thread with the card in shows on the box dx12 for the 285 cards coming.

DirectX® 12
The tessellation performance on AMD Radeon R7/ R9 series is up to 2X faster than the previous generation, and DirectCompute performance is also faster to accelerate advanced post-processing, filtering, and anti-aliasing techniques. Direct X12 games has never looked this good.

* Based on preliminary DirectX 12 specifications as of July, 2014, AMD’s GCN-based products are expected to support DirectX 12 upon its release. The DirectX 12 specification and support for it are subject to change without notice.

Hopefully they don't change the spec of DX12 then or that * might come in handy

That was what I was basing my answers off.

The low level bit of the dx12 api will be compatible with older cards so if thats the main thing ppl want i.e mantle in dx12 then no upgrade is required. Sure tho there will be a few things new hardware will help with but not needed for low level access which is mainly what ppl are wanting.

Gregster · 28 Aug 2014 at 18:04

Yer, maybe I misread the OP

So 780 ti's won't be full dx12 compatible?

No bud. There will be some blending and something else missing as I read it. Might be miniscule though but time will tell

bradUK · 28 Aug 2014 at 18:35

That's disappointing, I know that it'll be largely unnoticeable but I'd have liked full backwards compatibility. I read somewhere that all GCN boards will be forever fully supported by Mantle.

Still love my DHS though :-)

Gregster · 28 Aug 2014 at 18:40

Yer, I wouldn't worry personally but it would be nice to have everything DX12 has to offer working.

Whatever happened to 11.2?
