To test out this new video card from ASUS, the EAH4770 Formula, I will run it through a series of game tests and synthetic benchmarks to see just how the performance compares to that delivered by similar video cards, as well as its direct competition from the green camp, nVidia. The OverclockersClub test system will be run as listed, with the processor operating at 3.0GHz. The respective video card settings that will be used are the driver defaults, with settings made in-game as noted to provide as few variables as possible. The only deviation from this method will be to disable PhysX in 3DMark Vantage. I will only be testing from 1280x1024 up to 1920x1200, as any higher than this will result in a less than spectacular performance across the board.

After my experiences with the Sapphire HD 4770 being limited to clock speeds of 830MHz on the core and 850MHz on the memory, I was not surprised to see the EAH 4770 Formula have the same limitations. At this point Riva Tuner does not support the HD 4770 video cards but there are a few tweaks out there that you can use to make this a reality. Additionally, the successor to ATI tools has been released and can be used to overclock the 4770. After overclocking the Sapphire HD 4770, I felt there was more left on the table and with the opportunity to bench this card from Asus I realized just how much was left. 900MHz on the core was just stable enough to pass some of the benchmarks but not all of them so I I backed it down 10MHz at a time until I could pass all of the benchmarks. I used the same philosophy with the memory overclocking but started at the memory's rated speed of 1000MHz and jumped up 20MHz at a time until it became unstable. I ended up with just over 100MHz on the R740 core and 323MHz on the memory. Both increases are ones to be proud of for a card that competes with cards that cost more.
