7 – Radeon HD 6770 DC SL Conclusion

ASUS Radeon HD 6770 DirectCU Silent

The Radeon HD 6770 offers correct gaming performances. The HD 6770d is not able to compete with high-end graphics cards but it’s perfectly appropriate for most gaming situations. Under Hard Reset for example, the average FPS was around 50. And its position compared to the HD 5770. Globally, the performances are the same, but in some tests, I feel the HD 5770 is a bit more faster. After all, both cards are based on the same GPU.

Now the killer feature: the noiseless VGA cooler. Sure the card is totally silent under non-3D tasks (browsing, etc.). But under 3D applications, the card emits a very small noise, a kind of buzzing. So under 3D apps, the HD 6770 is not a 0dB cooling card as it’s claimed on the box!

The size of the DirectCU heatsink may be a problem in some cases like HTPC ones.

Under normal 3D applications, the GPU temperature does not exceed 85°C. This is hot but acceptable. The ideal situation would be a closed tower with very low noise fans to help the DirectCU cooler. FurMark is an extreme test that shows the max temperature the GPU can reach (100°C). This temperature is too hot. It’s out of question to have such high temperature permanently. If you encounter this case, you have to change something in your system (add some fans, etc.).

Final words: ASUS’s HD 6770 DC SL offers good gaming prestations with very very low noise (buzzing…). But the card must be placed in correctly ventilated place if you plan to run intensive 3D applications. Fanless card does not mean fanless case…
