Forums - PC Discussion - AMD APUs see significant performance gains from DirectX 12

I don't believe I related any specifics.

Except the lower figure is agreeable with the performance when the onboard GPU of the AMD APU is taken into consideration.  Since those have similar performance DDR3 memory, the performance increase should be comprable.

You were saying ?

I think a mod should edit that title. It's so misleading it hurts ^^;

I was about to make the exact same comment.  Nowhere in the article does it say anything like that.

Especially when we consider this:  "Looking at the overall picture, just as with our initial article it’s important not to read too much into these results right now. Star Swarm is first and foremost a best case scenario and demonstration for the batch submission benefits of DirectX 12."

I invite the OP to explain that title.

Yeah, that part really highlighted how silly this thread is... It's a shame too, the article would have made for some interesting discussion if it hadn't been turned into something it wasn't.

"Phil Spencer: DirectX 12 Won’t Change Xbox One’s Hardware and Graphics Capabilities

But sure....you know more than Phil. Part of the guys job is hyping up the smallest things.

This is the guy that said they have too many games....

I don't think Phil Spencer is saying there won't be any performance improvement.  However, no available API for any consoles utilizes multiple pipes to the GPU.

It's parralellism.   There is always a performance improvement in parralellism.  Hence the reason why GPUs use it and why Sony tried using it. 

If I have a lot of traffic going between two cities, having one two-lane road to that city will never be more efficient than having 8 two-lane roads.  That's putting DirectX 12 and what it will bring to the Xbox One in the simplest terms possible.  It has nothing to do with getting closer to metal, though it does that too, but the realized improvement in performance will be the ability to utilize mutliple pipes to the GPU from multiple CPU cores.  They all don't have to route to a single core, and they still do that regardless of the API on PC and console.  (I don't think Mantle is heavily utilized yet.) 

Personally, no, I'm not expecting a 60 to 200% improvement in performance.  My guess would be a 25% improvement in performance at the high watermark.



This sounds good! but why is the op talking about xbox? the article is about lowertier cpus, aka amds...

Then why don't you change the title ?

Seriously, you consider THAT a specific?  You're being pedantic.



The X1 already uses a mantle-like programming interface so there will be no performance-boost at all. Mantle is still faster and more efficient than DX12 according to recent tests. The concept of mantle and the ideas behind DX12 directly come from the X1 programming interface which already has most of these enhancements.

Because, math.  The percentage performance improvement with the AMD performance ratings in all but one scenario fits within those numbers or relatively close to them (i.e. 58 vs 59%). 

Take the finishing performance, subtract it from the original performance number, then divide that by the original performance number and that's the percent performance increase. 

If I created a thread using my own perfomance statistics, then I would have to sit here and run a real-world performance statistic for a game written for DX12 on the Xbox One.  I'm not doing that.  I'm utilizing someone else's thread to make a statement regarding potential performance improvements. 

As the article states, if you read it, the AMD APUs won't necessarily see that great of a performance increase, and in the results it doesn't.  But it's still roughly 59%.

If you want to refute the findings of the articles performance increase, and how that'll reflect on the Xbox One, please do so.  I would like to see you write an article where you do a real-world scenario (because this article isn't real-world) on the Xbox One and prove that there is no performance improvement as a result of the use of DirectX 12 when utilized properly.  That way, we can all see how wonderfully intelligent Fatslob-O really is.

Did I say that we won't see a performance improvement for the Xbox One when using DX12 ? Talk about straw man ... 

FYI, AMD A10-7800 & A8-7600 =/= X1 SoC ...



Hahaha hell no. You would be lucky with a 5% increase.
