New card running slower?

[MRGOOCH]

I just replaced a HD 5450 card which had 2 gb memory. This card ran very well for what I use it for [ no games ] 1920 x 1080 res . I replaced it with anothe HD 5450 1gb memory but has a DP port which I need for a new monitor I purchased. I am now using 2560 x 1440 res. and finding the system is struggling and when I watch videos on you tube it struggles at 720 res.
I checked and have the most current drivers.
Any help here?

YouTube does use video acceleration for playing videos. And that is a pretty high res for that older card, but it should be able to play games ok. You have plenty of CPU power for displaying them as well.

I would try with other browsers, be sure its not an issue there. You could also run MSI Afterburner and watch your GPU and CPU usage. See if maybe one of them is actually pegging out.

I don't understand why there is such a difference from my last card to this one. They are the same except for the memory.
My windows performance rating went down from 4.2 to 3.9

That is normal going from ATI TO NVIDIA or nvidia to ATI . you get issues and need clean install of OS. gl

The new firefox Beta cuts Flash out of the equation and uses HTML5 which is much more resource friendly (amongst other things) Chrome and IE also use HTML5.

 

[Stuka87]

Well, its possible the new one uses DDR3 or something instead of GDDR5.

It probably struggles because you switched from 1920x1080 to 2560x1440, maybe combined with Flash's poor video performance (also video in HTML5 isn't always better).
Does it play back offline video files fine? A newer generation card might help.

 

[MRGOOCH]

Video I have on file plays OK.

Try to go into your browser settings and enable hardware acceleration if it is enabled, and conversely disable if it is enabled.

Flash has been very unstable for me since donkey number of years, and now on more than one platform. Erm, even Android, the browser just keeps crashing every now and then. To be fair though, it isn't supported on Android anymore.

That option is not available

The HD 5450 was never offered with GDDR5, as it's an extremely low-end part.

More likely, he picked up a 5450 with 1GB of DDR2, which would dramatically impact performance. Something like this, for example: http://www.sapphiretech.com/presentation/product/product_index.aspx?pid=314&lid=1

If the OP wants to know for sure, he should provide us the model numbers for the products he has.

HIS H545H1GD1 Radeon HD 5450 Silence 1GB 64-bit DDR3

This model has the same GPU and memory clocks as most 2GB DDR3 models, so this wouldn't cause the issue. The WEI score might be affected by the reduction to 1GB, but that's unlikely (and isn't relevant anyway, as the card doesn't need 2GB for anything it could actually be used for).

I'd take a look at what's going on with CPU and GPU usage when playing Youtube videos. Task Manager should be able to tell you on the CPU side, and for the video card, you'll need something like MSI Afterburner.

I am also getting some audio distortion on some You Tube video's

Video decoding doesn't need fast graphics card memory. It's a not a 3D game.

I've recently added an ATI 4350 card to an old computer to help with video playback on the web. It also struggles. Local h264 1080p files play without a problem, for example with MPC-HC. But Flash or HTML5 video playback isn't the smoothest, despite the card doing all video decoding. I guess Flash and HTML decoders or renderers just suck.

 

[MRGOOCH]

I checked on Vimeo site and the videos play normal.

 

[Deders]

Maybe it's worth reinstalling the drivers.

 

[cen1]

Did you try different browsers? Especially with old drivers, HW acceleration can be really iffy.

 

[ZGR]

Check out HTML5 YoutTube?

 

[MRGOOCH]

Maybe it's worth reinstalling the drivers.

Has that ever made a difference?

 

[Deders]

Has that ever made a difference?

Most definitely yes, quite a few times in my experience. Try a normal re-install first, if that does nothing then try completely removing and cleaning up the drivers first.

 

[MRGOOCH]

Other than using the device manager to delete the drivers is there a better way?

 

[Deders]

Is there not an option in Add Remove programs/Programs and features? After that you can run this:

I once also bought HD5450 which couldn't play videos smoothly, issue was that card had 32bit memory interface instead of normal 64bit. That 32bit memory interface was also clocked very low, at 800MHz data rate, really a card grade lower than normal HD5450. Shame that AMD let manufacturers do such a ripp offs.

 

[MRGOOCH]

What did you replace it with? By the way I uninstalled and reinstalled the drivers.No change. The sound on Youtube videos is distorted?
