Sapphire HD 5670 1GB Review



Testing the Sapphire HD 5670 will consist of running the card through the OverclockersClub.com suite of games and synthetic benchmarks to test the performance against many popular competitors to gauge its performance. The games used are some of today's popular titles to give you an idea on how the cards perform relative to each other. The system specifications will remain the same throughout the testing. No adjustment will be made to the respective control panels during the testing with the exception of the 3DMark Vantage testing where PhysX will be disabled in the nVidia control panel. I will test the card at stock speeds and then overclocked to see how much additional performance is available and determine if it can run with or faster than the current fastest single GPU cards on the market. Of course, all settings are left at defaults in the control panels of each respective manufacturer except where noted. I will be using the latest drivers from each manufacturer at the time of this review.

  • Sapphire HD 5670 1GB 895/1040

The Sapphire HD 5670 was limited to clock speeds of 850MHz on the core and 1050MHz in the Catalyst control panel. To see what this card could do I turned up the fan speed to 95% and maxed out the clock speeds for the core and memory. The Catalyst Control Center test passed the clock speeds at 850MHz and 1050MHz respectively but was I was greeted with a black screen after a minute of 3DMark Vantage. The customary reboot was required to get the video back. Once back into windows I backed down the memory speed to 1040Mhz and was able to pass 3DMark Vantage and a 30 minute loop of Crysis warhead set to the Gamer preset. Now if you plan on trying for clock speeds in excess of the limits in the Catalyst control Center you should download AMD GPU Clock tool and MSI AfterBurner to make sure you get all the functionality you can. The reason for the two utility approach is that when you set the clock speeds in AMD GPU Clock Tool and apply the setting you default the fan speed to auto. If you go back into the CCC to change the fan speed you lose the clock speeds you set in the GPU Clock Tool. Goofy, but it's what happens. Enter MSI Afterburner - this application was written by the same person responsible for Riva Tuner over at Guru3d and is an easy to use interface that is already able to work with the latest cards from ATI and their partners like Sapphire. After loading up the two tools I started pushing up the clock speed on the Redwood core and was able to reach 900Mhz on the core but it was only stable through 3Dmark Vantage. When I went to start looping Crysis Warhead I was again greeted with a black screen. Backing it down to 895MHz on the core and 1040MHz on the GDDR5 memory took care of all the instability problems enabling a cool 600+ point increase in 3DMark Vantage scores.
