Testing with AMD GPUs: Doesn't Work Yet

Update 4: AMD has released Catalyst 9.11 with Flash support for Radeon HD 5000 series and 4000 series GPUs. No word on integrated graphics platforms. We've begun testing but the drivers don't seem to enable H.264 decode acceleration under Hulu at this point, waiting for a response from AMD.

Update 3: AMD tells us that Flash 10.1 support is coming later today, we should have a working driver soon.

Update 2: The latest beta drivers from ATI do not enable Flash 10.1 hardware acceleration support (both leaked and the supposed Catalyst 9.11 drivers from ATI's developer site). We're still waiting for ATI to get us a version of their drivers that does enable GPU acceleration under Flash 10.1.

NVIDIA's drivers are publicly available however:

Update: The Release Notes now indicate Catalyst 9.11 drivers are required, which would explain our difficulties in testing. We're still waiting on a version of Catalyst 9.11 from AMD that works with Flash 10.1. We will post updated data as soon as we have the driver.

I’d say that my ION testing went pretty smoothly, but the same definitely doesn’t hold true for AMD.

I setup an AMD 785G system (integrated Radeon HD 3200) with a AMD Sempron LE-1150. This is a 2.0GHz, single core, K8 based processor with a 512KB L2 cache. Definitely faster than an Atom.

The integrated graphics of the 785G chipset fully supports H.264 decode acceleration and shouldn’t have a problem with Flash 10.1. AMD has it on the supported list and things should be smooth. Unfortunately, the numbers don’t agree:

Windowed Average CPU Utilization Flash 10.0.32.18 Flash 10.1.51.45
Hulu Desktop - The Office - Murder 97% 100%
Hulu HD 720p - Legend of the Seeker Ep1 94% 100%
Hulu 480p - The Office - Murder 57% 60%
Hulu 360p - The Office - Murder 27% 35%
YouTube HD 720p - Prince of Persia Trailer 90% 100%
YouTube - Prince of Persia Trailer 8% 8%

 

Not only did CPU utilization figures not go down, in many cases they went up. I asked Jarred to help me with a sanity check. He had a notebook based on the mobile version of the same chipset with an Athlon 64 X2 QL-64 (dual core 2.0GHz) and ran his own numbers:

Windowed Average CPU Utilization Flash 10.0.32.18 Flash 10.1.51.45
YouTube HD 720p - Prince of Persia Trailer 46% 46.5%

 

There was no change in CPU utilization when moving from Flash 10.0 to 10.1.

The two of us did notice something however. Flash 10.1, although not perfect on AMD hardware, did seem to improve performance. Jarred measured the number of dropped frames between Flash 10.0 and 10.1 in our YouTube HD test:

Windowed # of Frames Dropped (lower is better) Flash 10.0.32.18 Flash 10.1.51.45
YouTube HD 720p - Prince of Persia Trailer 289 frames 212 frames

 

There’s a definite improvement in 10.1, but just not nearly as much as we saw from NVIDIA.

I tried a few more things before giving up on AMD. I tossed in a Radeon HD 5850 to see if it was the integrated GPU at fault - still no change in CPU utilization. Finally I upgraded processors and used an Athlon II X2 240 instead of the meager Sempron.

Full Screen (1920 x 1200) Average CPU Utilization Flash 10.0.32.18 Flash 10.1.51.45
Hulu Desktop - The Office - Murder (Sempron LE-1150) 100% 100%
Hulu Desktop - The Office - Murder (Athlon II X2 240) 80% 72%

 

CPU utilization finally went down, but not nearly as much as what we saw with NVIDIA. There’s something not quite right about how AMD’s hardware interacts with the Flash 10.1 preview; I guess that’s why they’re calling it a prerelease.

    Most control panels are crutches for poor operating system and application developers. I have never touched ~95% of settings in such control panels, and AA settings belong in the application, if any. These sorts of things should be non-issues. Same with sub cutoffs. That belongs on the amp/receiver. Even if I'm completely off base, there's no reason the travesty that is any current control panel should look the way they do. Honestly, skins in Catalyst? What - the - fuck.

    The ONLY three things I ever do in a graphics card control panel are 1) adjust flat panel scaling, which It should never be on anything but maintain aspect ratio, 2) adjust black levels, which I should never have to do with a properly calibrated monitor and 3) adjust multi monitor options because for whatever reason nVidia and ATI insist using their own ultra shitty implementation instead of the only somewhat shitty Windows implementation.

    You got me on the C2Q playing back video, although if you start doing anything else CPU intensive, that wont last. Imagine playing back TWO videos?!
  • Cerb - Saturday, November 21, 2009 - link

    Sorry, but no. Having settings in the application means that if the application was not designed to use those features, you can't turn them on. Any features implemented just by the driver and hardware should be controlled entirely by the driver and hardware. The user should then have a front-end to control those settings.

    Games should have the minimal amount of settings for anything not programmed into the game. The driver should have everything else. AA is one that should especially not be controlled by the game itself. AA controlled by the game means the game can turn it off, which should never happen. I would return a game that did that in a heartbeat (I've been having AA always on since Quake 2 and Tribes on a GF2 GTS--which would not even be possible if it were a game setting--and am not turning it off until pixel size becomes at least 1/16 what it is now on LCDs).

    The game should never get to decide what settings can or can not be used. Likewise, audio applications should not have to know about my speaker setup, just send data to the driver API. Video should be the same way: define the stream, send it to a demuxer, have that send the video portion to a black-box decoder API. it doesn't always end up working out perfectly, but that's why default settings tend to be the most widely compatible ones.

    Not all such control panels are well thought out, but they have their place. In some cases, they are OS/app crutches (multimonior and color tuning, FI), but they are quite useful beyond that, and would not disappear, even if all the crutch-like settings could be done away with.

    The problem is that AA doesn't work properly using some methods unless it is built into the game engine. Never mind that with pixel and compute shaders, it is now possible to do AA within the game code and not have it impact performance as much (i.e. DX 10.1 enabled games). I don't think you can make a case for either direction: i.e. it shouldn't ALWAYS be controlled by the game, and likewise it shouldn't NEVER be controlled by the game. Similarly, trying to control that in the driver won't always work (but it sometimes will).

    IMO, the only reason we have the setting in drivers is because games are often not forward thinking, limiting what setting they will or won't support. Assassin's Creed for example decided that any resolution above 1680x1050 shouldn't be allowed to run AA. Stupid. Older games were made before AA was even a consideration. All new titles should look at implementing AA internally, in an optimal manner, with the ability for the user to turn it on or off. Thankfully, most games are doing exactly that.

    Another case for why AA should be in the game/application and not the driver: say game X runs perfectly well at 2560x1600 4xAA, but game Y can't do more than 1920x1200 0xAA, and another game can run 2560x1600 0xAA, and yet another 2560x1600 2xAA.... You get the point. If you control the setting within each game, you set it once and forget about it. If it's a driver only setting, every time you decide to play a different game, you have to enter the control panel for the drivers and change the setting.

    Saying AA should be only in the control panel is just one step up from saying games shouldn't even be able to specify what resolution to run at. I think we can all see how ludicrous that would be, and by extension forcing the driver to tell games what AA (and HDR, etc.) to use is equally limiting. The application knows what to do best, and the drivers are just an interface that talks to the hardware and interprets common function calls.

    playing back full hd videos without hw decoding does actually even work on a c2d, no problem so far.

    just not with flash, as it's horribly inefficient.
  • JarredWalton - Friday, November 20, 2009 - link

    A reasonable Core 2 Duo with GMA 4500 or better graphics should be able to handle Flash HD at up to 1680x1050 without trouble, even with Flash 10.0. The problem is that a lot of netbooks, nettops, and entry-level laptops don't have even that.

    Flash sucks big time,and is largely unwanted on the internet!
    Instead of displaying movies in Flash, websites would have done better with streaming DivX/XviD or OGG/Mp3/WMA or so.

    Flash is as much an internet hog as REAL was in the real networks days.
    They are low in quality, require high CPU, and display few FPS.

    I prefer the internet to become like a mobile internet, without ads, and just the minimal info visible necessary to do the most basic internet tasks (like this article, a few .jpg's, and a non-java based forum or thread underneath where we can type.

    Many websites won't exist if it wasn't for the ads you may say, but I'll reply to them:
    "So where is all that money going to that they get or pay to keep their website online? Who's on the head of the chain? The government?"
    The internet was supposed to be a free thing, the only ones who should charge are the companies who place cables which carry the signals, and the renewal of the servers.

    We're living in 2009, back in the '80, it could cost you quite some bucks to have 20MB of online server space!
    Nowadays, they charge quite some to, while giving you 50MB of web space! I mean, what is that?
    It costs a company today $90 to get a 1TB HD!
    And if they got rid of flash altogether, internet pages wouldn't take up more than a few hundred of kilobytes.
    A 1 TB harddrive could be enough to give 10.000 customers a 100MB webspace for $10 per person, which is almost for free.

    But no,if you have a big website, they charge you hundreds of dollars per year, sticking a big fat bonus in their paychecks, because a server does not cost a company $100.000 anymore. They nowadays can easily be made for 1/10th of that price, yet they still charge too much.
    That's why the world must be terrorized by flash ads.
    I'm glad someone got some sense to create an ad blocker for my browser; because that not only seems to ease my reading of the page, it also reduces my overall network traffic, lowers CPU usage, and therefor increases battery life on my notebook, and it keeps me safer from hackers trying to enter into people's computers through annoying popup ads, using the weaknesses of flash.

    The world would be a better place if flash was never invented.
    Even those little tasks you do in flash,like playing farmville in facebook, perform much better if it was only an executable file for download, instead of a flash game!

    "It costs a company today $90 to get a 1TB HD! "

    My employerr had to pay $120k for a new 16TB SAN cabinet and that doesn't include local back-ups or off site storage/back-ups

    I wish storage was only $90/TB, I could get a raise.
  • snarfbot - Monday, March 8, 2010 - link

    well did he really have to?

    seems like a bad time to invest that much cash when the entire storage industry is transitioning to solid state.
  • autoboy - Tuesday, November 17, 2009 - link

    Do you have any clue how the world works?

    People provide services. In exchange for those services, they get paid. Their pay allows them to buy your services. People who provide services people actually want get paid, while those services that people don't want fail. Government steals 50% of your pay to build roads, police crime, and perpetual failed social programs.

    So, the internet is supposed to be free with no business model?

    Sound good to you Anand?
  • fic2 - Tuesday, November 17, 2009 - link

    A 1T hard drive might cost YOU $90, but for a server company it cost quite a bit more. Or do you and the 10,000 other customers not care if the 1T is RAIDed and backed up? I am not sure what else goes into to it since I don't do that, but I would guess they also have to pay for space/electricity/AC/people/internet/etc.

    Oh, I'll add that I hate flash, too. Especially the idiot websites that think their front page has to be flash based.
