Edit: apparently the number of compute queues the anandtech article lists is incorrect

So from my understanding this is basically hyperthreading for gpus? Also i'm pretty sure nvidia did something with their maxwell gpus to reduce latency and stutter for VR and here amd also touts improved VR experience so its nice to see that amd isnt being left behind on something. Hopefully developers properly implement this feature; it would be a shame if it goes largely unused.

Isn't this what Nvidia was using to explain G-Sync?

About how Data is processed? And displayed? Or am I just 1/2 asleep?

? asynchronous shaders

Around 0:38 I remember Nvidia saying something very similar to that as an example of Gsync.

I think this is awesome, I'm just amazed how chaning little things like the way handling ques can increase efficiency and performance.

Kudos to AMD and their partners.

i dont think g sync does anything to make the gpu more efficient idk

I know, I just remember hearing them describing what the GPU does the same way they did in the video @ Around 0:38

Can't find it, I think it may've been a Slide show.

You do realize that this was available already in GCN?

AMD cards have been way more complete when it comes to features then the competition, for quite some time. The problem is that they are not using them.

For example, true audio was a great idea, even to offload tasks from the CPU - where is the implementation? Even with the PS4 having a similar chip, it was used only in one game if i recall correctly.

So is this a preemptive excuse for not reworking their DIEs?

Strange how something that sounds so completely logical can actually be so hard to achieve.

Here's hoping it will be as big a step forward as they claim.

? their gpus are fine

Well all those pistons going up and down. No wonder their GPU gets hot. Not a Nvidia fanboy.

This is a repeated comment and I can't delete. Luke, you need to look into adding that feature.

I can't stop laughing pistons going up and down lol.

wat

 

First of all, what do you mean by "complete"? Don't give me that one example of the 3.5 gig VRAM bullshit.

 

Secondly, audio being played back doesn't take that much at all, to my knowledge. It's the same thing as adding an old Nvidia card as a dedicated PhysX card to a 980. It's not going to do anything.

 

Also, according to Wikipedia: " Murdered: Soul Suspect, Star Citizen, Thief and Lichdom: Battlemage" all have True Audio implemented.

"Complete" when it comes to hardware features. For example : up to date controllers (like dp1.2a).

It's not "audio being played back", it's audio processing. From what I recalled in a game engine, on average, 20% of the CPU load is audio processing, and that could be offloaded to TrueAudio. It's not for improving GPU performance, it's overall performance.

Thank you for that list, I haven't checked on it for quite some time, and when you need to check wikipedia to know it... then it's not that well advertised and spread like I said.

To be far though cpus are not usually the bottleneck so while it's a nice feature and does have benefits, they won't be truly felt until devs are able to fully harness cpu power.

I'm sorry, but that was the same argument people made about Mantle : "Oh such thing will only be usefull for low end CPUs..." then someone has to remember them that High End CPUs reach bottlenecks with MultiGPU setups.

Nvidia just implemented this with Maxwell right?

I think that AMD cards are better in computing performance. Their normal "consumer-grade" GPU's have lots of computing power if you compare them to Nvidia cards.

Hope they release something because Nvidia were dominating with the 970 before dropping prices. They need new stuff :/
