Not sure if Radeon HD 8330 is working fully.

post #1 of 7
Thread Starter 
So, I recently bought a Gateway NE series laptop with an HD 8330. It doesn't seem to be working. Now, I don't expect to go and play Planetside with this thing, but I should be able to play TF2 right? When I run TF2 on absolute minimum graphics (and native 1366 x 768 resolution) the FPS dips as low as 5 fps. Here are some other numbers:

DotA (medium settings): 11 fps
Tribes: Ascend (low settings): 23 fps
Stone Giant (medium tessellation): 8 fps
TF2 (medium settings): as low as 7 fps, depending on environment
Hawken (low graphics): 10 fps

On TF2 and DotA the GPU's use continuously cycles from zero to 100 percent about once every two seconds. These two games should be the least graphically challenging of the games I tried, but they aren't really playable. This makes me think that maybe there is some kind of problem with Source games. Do you know what problem I'm experiencing and how to fix it? Or am I overestimating the ability of this GPU?

All I know is that my brother's laptop, which doesn't even have an independent GPU, runs all of these games at least adequately.

Any help is appreciated.

Thanks, Aidan

I think its your gpu http://www.notebookcheck.net/AMD-Radeon-HD-8330.92874.0.html

I'm guessing that's an APU (CPU + GPU combo), do you know the exact model? Unless it's heat throttling, my guess is that the CPU portion is very weak.

Tyrandis's link says "Depending on the benchmark, the performance of the Radeon HD 8330 is similar to the average Intel HD Graphics 4000" and I've played games on Intel HD 3000 graphics at that resolution so the GPU seems capable enough for that.

I have heard some stuff about it being an APU. It is an AMD quad-core A4-5000. It's no powerhouse, but I would think that it would be up to the task. I have checked CPU use under load, and it varied. In the games where the GPU throttled it stayed at about 15%, but in other games it was at about 60%. I did wonder if the usage of the CPU might be effected in some way if it was an APU.

Is this an APU we're dealing with? If so, why does it have both a processor and a GPU labeled?

Yep it's an APU. Not sure I can explain why CPU and GPU have separate labels, probably just so you can gauge the performance or do a model comparison at a glance.

I just looked at a review of the A4-5000 ( http://www.techspot.com/review/671-amd-a4-5000-kabini/page6.html ) although the benchmarks there are more intensive games at a slightly higher resolution it's pretty telling that most of them aren't >20fps. Looks like the A4-5000 cpu part is pretty weak, especially if the game can't full take advantage of a quad core. TF2 is multi-threaded but probably not the best example of a game that can take full advantage of a quad core. Maybe drop the game resolution to 1024x768 will give you more playable FPS.
