News - Intel demos big power saving and FPS boost due to DirectX 12

DirectX 11 and 12 compared using Microsoft's Surface Pro 3 (Intel HD440 GPU).

Wow, I am surprised at Intel being this fast on the demo.....DX12 stuff is very thin on the ground.

Surface Pro 3 with Broadwell and DX12... count me in

The question is will we see an increase in FPS when thermal and power constraints aren't a factor, i.e on our common-or-garden gaming PCs.

Something is always a constraint, but like mantle, this is showing a reduction in CPU overhead, so if your CPU was limiting DX12 should improve FPS. Even if your CPU isn't limiting, reducing CPU time still has some benefit, though not the great gains you'll see here.

Your probably either going to see an increase in FPS or a decrease in power usage....or a bit of both.

And if you see a decrease in power usage, then you see it in thermals. thus you can overclock more for more fps

This is the key point, especially for smaller form factors where thermal management is much more important. Hence their comments about 'CPU bound vs GPU bound' being redundant in future - if you can manage the thermals well enough, you can find extra performance where you need it.

Hhmmm - looks like the CPU is less of a bottleneck so no need to buy the really expensive Intel chips anymore, better to spend the extra on a better GPU.

...errr that was the point of the demo right?

I'm a noob, so sorry if this is a silly question.

I'm planning to get a 780 Ti in a few weeks and I've read that I'll be able to update it to be compatible with DirectX 12. Will the update include all features or am I better off waiting a little longer for the 880 to release?

Well, DX12 is mostly a software thing, so it's likely that all cards will be able to run the software side of DX12. However if there are any features that require hardware changes then the 780ti probably won't have them. That said, I don't know that the 880 would either - DX12 is still some way off. We don't even know what version of windows it'll require.

I'd read somewhere it was releasing around christmas this year, but I've been trying to find more info since my last post and it seems they were completely wrong. I think waiting would definitely be a waste of time.

How do I thank a post?

The first DX12 games were touted for release around xmas 2015 not 2014. So we are still looking at another 15 to 16 months.
