AMD Radeon HD 3200 / 780G
AMD 780G On Linux:
We will be delivering board reviews of the 780G-based ECS A780GM-A and ASRock A780FullDisplayPort in the coming weeks, but today we are exclusively looking at the Radeon HD 3200 graphics performance. The Radeon HD 3200 (780G) is supported by the Catalyst 8.3 driver and xf86-video-ati git code on Linux. Open-source RadeonHD support for the 780G chipset is presently under development, but with their anti-AtomBIOS stance, it is likely some weeks away. The 8.3 Catalyst for Linux package (fglrx 8.47 driver) fully supports this chipset and was properly identified as the Radeon HD 3200. The Catalyst 8.3 driver on Linux even supports DisplayPort, for those having DisplayPort-capable hardware.
For this article we had used the ECS A780GM-A motherboard with an AMD Phenom 9500 processor, 2GB of OCZ DDR2-800 Reaper HPC memory, Western Digital 160GB SATA 2.0 hard drive, and SilverStone Zeus 750W power supply. The ECS A780GM-A motherboard has one analog and one HDMI port. We had compared the Radeon HD 3200 performance against the Radeon HD 2400PRO 256MB (for which this IGP is based) and the Radeon HD 3650 512MB graphics card. The 780G had allocated 256MB of system memory for its video frame-buffer.
Linux benchmarks ran with this IGP and two PCI Express graphics cards had included Doom 3, Quake 4, Enemy Territory: Quake Wars, and GtkPerf. Each 2D GTK test was ran 1,000 times with GtkPerf. Due to the lack of AMD OverDrive support under Linux, all graphics solutions were ran just at their stock frequencies. The Linux distribution used during testing was Ubuntu 8.04 Beta with the Linux 2.6.24 kernel.
