From these test results we see the Radeon HD 3300 (790GX) does have a moderate advantage over the Radeon HD 3200 (780G), but it is still left far behind the Radeon HD 3650. In Nexuiz 2.4 the Radeon HD 3300 IGP had nearly a six frame per second advantage over the Radeon HD 3200 IGP, or 17% faster. In other tests, however, the 790GX performed much closer to its 780G predecessor.

In only the 2D performance benchmarks was the Radeon HD 3300 series performance worse than the Radeon HD 3200. When it came to utilizing GtkDrawingArea Pixbufs, the 790GX was nearly five times slower. The 780G itself performs much faster than the discrete Radeon HD 2400PRO and Radeon HD 3650 graphics cards in these 2D GTK operations due to the IGP using the system's shared memory and that being an advantage with this simple drawing. For whatever reason though (likely an fglrx driver bug), the 2D performance was worse off with the 790GX.

With integrated graphics processors often finding themselves within Home Theater PCs, video playback is also quite important. However, at this time there isn't much to say. The Catalyst Linux driver supports X-Video right now but many users are currently troubled with tearing issues. AMD's Unified Video Decoder 2 (UVD2) may finally be supported on Linux this month with XvMC and HD video support, but that has yet to be officially announced so you will just have to wait and see what comes about with this Linux video support.

On the open-source side of things, if all you care about is mode-setting for the 790GX you can be set with either the xf86-video-ati or xf86-video-radeonhd drivers as both rely upon AtomBIOS. There is no open-source acceleration support yet for the ATI R600 and R700 series.

With Catalyst 8.9 at least, the performance boost over the 780G Chipset is quite small. The AMD 790GX though does possess other advantages such as the newer SB750 Southbridge, which makes it a better offering for those pursuing new motherboards. We will have more on this chipset in the coming days as the ECS A790GXM-A review is completed.

If you want to compare your system's graphics performance to the Radeon HD 3300, using the Phoronix Test Suite run phoronix-test-suite benchmark michael-1083-3336-9623.
