Graphics card testing comes in two flavours: synthetic and real world. This means running some benchmarks in each of these flavours and graphing up the results in comparison to other cards. However, since this is a HTPC type GPU, I’ll be using the XSR media centre test setup.
The benchmarks used were:
- 3D Mark 11
- Custom PC Benchmark suite
- STALKER Clear Sky
- Aliens vs Predator
CPU: Intel i3 2100T
RAM: Corsair XMS3 4GB 1600MHZ
Storage: Corsair F40 40GB SSD, Seagate Barracuda 1TB LP
Case: Zalman HD503
For all other tests, I used a Zotac GT430 for comparison purposes.
Not the most up to date 3Dmark, but certainly a strenuous enough test for this little GPU.
NB. Due to time constraints, it wasn’t possible to get the comparison results for this test.
Respectable results from the 6670 here. I didn’t expect it to do quite as well as this. It wasn’t long ago we’d have been impressed by scores like this from a top of the line GPU.
Custom PC Benchmark Suite
This is a series of media based benchmarks put together by Custom PC. It features some processor heavy tasks, but media watching and image manipulation can be accelerated by GPU hardware so it’s worth running.
Some interesting results here where the 6670 just about keeps its head above water, beating out the GT430 by just a few points.
STALKER Clear Sky
This game’s getting on a bit now, but it still provides a reasonably good DirectX 10.1 environment to test a GPU in.
- 1280×1024, default quality, full dynamic lighting
- 1280×1024, extreme quality, full dynamic lighting
- 1280×1024, extreme quality, enhanced DX10 lighting, 8xAA
- 1600×1200, extreme quality, enhanced DX10 lighting, 8xAA
Obviously neither of these cards are designed for high level extreme gaming, but it’s interesting to see how the 6670 falls down quite a bit at the higher details, yet dominates completely at lower resolution and detail levels.
Aliens vs Predator
This benchmark makes use of DirectX 11 and therefore tests this card’s ability at dealing with a more modern environment.
For this I used the official benchmark video, with the Benchmark Tool from Guru3D to manage the settings.
- Low – 1280×1024, no AA, Medium Settings, Medium Shadows
- Medium – 1280×1024, no AA, Very High Settings, High Shadows
- High – 1280×1024, 4 SSAO, Very High Settings, High Shadows
- Ultra – 1600×1200, 4 SSAO, Very High Settings, High Shadows
At the lowest of the low, the 6670 could probably power through and give you a mostly playable experience, but you’d notice occasionally slow downs.
Temperature / Wattage
Here is where you’d want the 6670 to shine. It’s got a specifically designed cooler to make things different, either more powerful or quieter – preferably a combination of both.
These results are taken by loading the system with
This is far from monstrous, considering the load figures are close to what the idle numbers are on most high end gaming systems.
This card never reached over 65 degrees C even after more than 30 minutes of high end Furmark burn-in testing. It’s a capable little cooler, but is it quiet?
Here is the only real problem I have with the 6670 and it cuts to the core of this product. It’s not silent when it gets hot. It’s far from loud, I would even say it’s quite quiet, but if you’re running a passively cooled system and you expect to game or do anything that’s graphically intensive, you’ll be able to hear this fan. Not over the noise of whatever you’re doing, but if you want a silent setup you’ll not want to buy this card.
