Well... Virtu MVP allows you to use QuickSync in apps while your Radeon is the primary card, and adding an Nvidia card with a hacked driver will give you PhysX, so it's absolutely possible to have all 3 without blowing up your OS.

Hey.That_Dude

With Hacks. I think it was implied that he wants that ability without hacks.

OK! IF YOU'RE GOING TO DO THESE ANNOYING BOT CATCHERS WITH EVERY POST THEN DO SOMETHING FUNNY, LIKE A DIFFERENTIAL EQUATION OR TYPING OUT PI TO 20 PLACES! OTHERWISE THIS IS GETTING QUITE ANNOYING.

And for some reason not on any of the high-end and mid-range Radeon HD 200x cards. Nice one AMD, tell us about a new feature and then don't put it on the cards at all.

Jesus H Christ can they just give a straight no-PR-bullshit answer of what it is? To me it sounds like a yawn-worthy low end sound card integrated with the GPU. Not like modern cpu's are taxed with audio processing now anyways.

Did you even read the article? Apparently using the CPU to process physics based sound effects is taxing, and the latency is too high for use in real time. Trueaudio is supposed to process the sound before it reaches the sound card, and make things like the reflection of sounds possible and more realistic.
This sounds(no pun intended) promising, simply because after Vista killed hardware based sound, we have had no improvement in in-game sound. If they get enough to support this, future sound cards could be relegated only to role of the delivery of sound.

Has ATI Radeon card improved since AMD took over? I had a few but always went back to NVidia. Onboard isn't as bad currently as it was in 2003 with NForce =)

I have a creative Recon but I wish I never bought it....

Good stuff...

Am I the only one who noticed this mistake in the second point of the first slide:

'...to bring take their...'

That makes no sense, it should read:

"...to bring their..."

Or:

"...to take their..."

Redundancy. Redundancy.

How come games don't support WASAPI or ASIO?

If it isn't being used for audio can it be used for something else?

Even though you tried to coax an answer out of them, AMD didn't really give us a reason as for why their new mid-to-high-end GPUs don't come with this audio tech and only the low-end (7790 rebrand) and the yet-unannounced ultra-high-end GPUs have this tech.

I think that AMD's comments about heavy CPU utilization during games are wishful thinking. I wish that games took more than 2-4 threads but the ones that I'm playing don't. I suppose that when so many games are ports from a console that only had 3 CPU cores I shouldn't be surprised when my games only use 2 cores.

They intentionally cripple HDMI output with Windows-only DRM.
They claim to be "open", but deliver the worst Linux drivers ever.
They cut corners to win benchmarks.

Fuck ATi.

Why are you still calling them ATi?

Thats the same as being angry with a Geforce GPU and saying

"Fuck 3DFX"

In fact yeah, lets start doing that. The 3DFX GTX Titan. 3DFX Tegra4. 3DFX 780.

EDIT: I'm familiar with 3DFX cards. I actually had a Canopus Pure3D myself back in the day.

I hear ya on that. And I'm going to start doing that too.

The phoronix article that comes up first on Google admits that it wouldn't make sense for it to be a DRM feature. Either way, if the exclusion of a DVI too HDMI adapter when using binary-only drivers while OSS drivers are readily avaliable is a dealbreaker for you, you must be missing the point entirely.

At least they provide open drivers at all. When Nvidia pulls shit like this, the linux community is SOL.

I have absolutely no clue what you're talking about here. W

Linux and Win user as well, I wish I could plus 1 this right now.

For acceleration?

Mesa 9.2 Git

http://cgit.freedesktop.org/mesa/mesa/

and the 3.10 kernel, which was just updated recently.

http://www.linuxtoday.com/upload/linux-kernel-3.10.12-is-now-available-for-download-130914120007.html

Reminds me, got tell my buddy Lu about this (pulling our hair out trying to get the 6700 DDR 5 to play nice with unbutu 12.10 LTS). But yeah, check it out.

HDMI output was crippled from inception.

I blame this on its developers focusing more on the utterly worthless (except to annoy paying customers) HDCP DRM scheme than on making a technically sound product that wouldn't be able to drive 4K @ > 30 Hz.

avatar

Hey.That_Dude

That has more to do with the signalling scheme than with the dedicated HDCP line. (Yeah, it has it's own dedicated pin to pin contact on the connector, seriously wasteful.) They chose a signalling scheme that really couldn't go up from 1080p (because it was never thought people would get past that resolution...) That and the MPAA got into the design with a "we wont release source for you to use unless you add a dedicated security system and design it so that people can't steal our junk off of your cable!" attitude. We all know how that turned out. People still stealing their junk... just not off of the HDMI cable.

I was getting excited for a munite.

I was thinking that this would actually be an audio output on the card I could utilize for streaming. I would love to handle all the audio processing on the card itself.

I cant figure out why, after all these years of shoutcast and Icecast (and all other media servers out there) why no major hardware company (especially Sound blaster) has created a sound card with streaming audio in mind. Between all the Justin.TV/ Youtube Live/ Veetle/ SC and IC/ WOWZA users, you would have figured just ONE company would have made hardware that works hand in hand with a custom DSP to stream.

avatar

Hey.That_Dude

So, basicly, what you want is a NIC that pulls streaming audio off, applies that data through a DSP and pushes it out through a DAC to your speakers. Why is that a good idea? The self contained approach would just add redundant systems that you don't need. What AMD's done is just add a DSP into your box. Before this, your CPU emulated a DSP in software. Even this DSP has some amount of software emulation otherwise it wouldn't be so extensable.
Therefore, since it's just code, Code it up. You want it. According to you, everyone wants it because it just sucks billions of cycles out of your CPU. Sounds like a good business. (unless one of the assumptions you've made is wrong)

avatar

Hey.That_Dude

Great Article. Love that last question. Lets work on cross platform development where at all possible. (I understand hardware is one of the last places cross development happens)

"That’s right, a sound card with audio support."
lol, i think you mean graphic's card right?
(second sentence)
And yes thank you Gordon, that was a lot of what i wanted to know about TrueAudio.
