Our test system for these launch-day benchmarks had an Intel Core i7 870 Lynnfield processor clocked at 2.93GHz with Hyper Threading (8 logical cores) and Intel Turbo Boost Technology enabled, an Intel DP55KG Kingsberg motherboard, 2GB of DDR3 memory, a 64GB OCZ Vertex SATA 2.0 SSD, Cooler Master 1000W power supply, and a Samsung SyncMaster 305T 30-inch LCD display. On the software side we were running a development snapshot of Ubuntu 9.10 (x86_64) with the Linux 2.6.31 kernel, GNOME 2.28.0, X Server 1.6.3, and an EXT4 file-system. During the testing process, Compiz was disabled, but all other settings were left to their stock values.
The hardware and software configurations were maintained while testing the Radeon HD 5750 and Radeon HD 5770 as well as an ATI Radeon HD 4670, HD 4770, HD 4850, and HD 4870 for comparison. The Radeon HD 4670 used for comparison had 512MB of memory and was clocked at 700/1000MHz, the Radeon HD 4770 offers 512MB of memory as well with 750/800MHz clocks, the Radeon HD 4850 has 512MB of memory with 625/993MHz clocks, and the Radeon HD 4870 has 512MB of memory with 750/900MHz clocks. To recap, the stock Radeon HD 5750 offers 1GB of GDDR5 memory with 700/1150MHz clocks, and the Radeon HD 5770 has 1GB of memory as well but with 850/1200MHz clocks.
For our initial round of AMD Evergreen testing on Linux we used the Phoronix Test Suite with the Nexuiz, VDrift, Doom 3, Enemy Territory: Quake Wars, Unigine Sanctuary, Unigine Tropics, Lightsmark, GtkPerf, and QGears2 test profiles. Now onto these Ubuntu Linux results.
