Sapphire Radeon HD 4670 512MB
Our test system for the Radeon HD 4670 consisted of an Intel Core 2 Duo E8400 clocked at 4.00GHz, an ASUS W5E64 WS Professional (Intel X48) motherboard, 2GB of OCZ DDR3-1333MHz memory, Western Digital 160GB SATA 2.0 hard drive, and an OCZ EliteXStream 800W power supply. In comparing this graphics card's performance we had also proceeded to re-benchmark the Sapphire Radeon HD 3650 512MB, Diamond Radeon HD 4850 512MB, and an ASUS GeForce 9600GT 512MB graphics card. Throughout all of our testing we were using Ubuntu 8.04 (32-bit) with the Linux 2.6.24 kernel and X Server 184.108.40.206. On the side of the Phoronix Test Suite we were using 1.4.0 Alpha 1. The ATI Linux driver in use was Catalyst 8.9.
With OverDrive on Linux having arrived last month with the Catalyst 8.8 driver, this is the first graphics card review where we were actually able to do any overclocking on Linux. OverDrive on Linux is right now all command-line based as it has yet to be integrated with the AMD Catalyst Control Center Linux Edition (AMDCCCLE).
