When Considering fantastic DX12 performance improvements with old hardware, remember that both Intel and AMD want/need to sell you new hardware...

Leader of DirectX 12 development dies in mysterious helicopter accident :D

But AMD and Nvidia also want to sell more graphics cards. I expect more people would pay £150 to £200 for a new graphics card than having to buy the same amount plus £200 to £300 for a new system.

Exactly, same can be said for those picking one or two benchmarks to prove old cpus are suddenly going to become relevant again.

I agree. I don't know why or how this became a hardware thread about AMD vs. Intel... just kidding, I totally know, the opening of the thread sounds like is putting an AMD piece of hardware in a positive light, some here won't have that. This thread should be about how much more efficient DX12 is than it's predecessor in this bench, and how a weaker CPU gained the most improvement. It shows promise for DX12 being a big deal, but that's about it.

All the previous API reductions have pretty much been used up before release.

If there is a dual path with DX11 and DX12, I agree the promise of better DX12 performance on weaker hardware can be true. But we see a lot of DX12 only games coming due to Xbox One ports. And it may quickly become the norm. And in that case developers will simply gobble up any reductions and use it for something else.

I'm speaking of claims that old CPUs are suddenly going to be good for high end gaming again...

Agreed -- People need to keep in mind that the Phenom II 955 is still reasonably potent today because Moore's law has slowed if not stopped.
You can probably game reasonably well on that antique CPU as long as you don't get carried away with the settings.

Serious question, would DX12 make my Q9300 CPUs (2.5Ghz Core2Quad) viable for gaming again? Say, with a R7 260X 2GB, R9 270X 2GB, GTX950 2GB, or 7950 3GB?

I recently inherited an Alienware Area 51 with the similar Q9400 -- and it plays modern games remarkably well. Although, the resolution is drastically lower (900p) that my usual 4k gaming rig.

You do realize you can get an i7-6600k, a $60 motherboard, and use everything you have on it including the DDR3? The PSU, the HDD, except any IDEs. You will have to anyway when you realize the performance to drive VR is required.

Can't use my DDR2 :D

It is more efficient,it does get you better performance,it does show promise
BUT it's only for the graphics...
If anything else needs CPU single speed like enemy AI or whatever a slow multi core will still suck since even if only one thread needs speed it will drag all other threads down with it.

Games are not multi threaded they just run multiple separate tasks at the same time,this means they have to synchronize between them,making the graphics part really multithreaded only get's you so far if every other thread runs slowly.

So game benchmarks,since they always only focus on graphics,will show big improvements,actual gameplay?! We will have to wait and see.
