Sapphire HD 4870 1GB Toxic Review

» Discuss this article (10)


Now down to what we all have been waiting for. To test the Sapphire HD4870 Toxic, we will be putting it through a series of benchmarks designed to push the card to its limits. Then to compare the performace of the Toxic edition to other current cards on the market we will place those scores against them and see where it stands. All hardware will be run at their stock speeds, timings and voltage to avoid any errors in the scores. The NVIDIA cards will be run using driver version 180.87 and the ATI cards will be running the 8.12 release of Catalyst. Due to a monitor hardware failure, we could not run the benchmarks at 2650x1600 at this time, however they will be added once the issue has been resolved so check back.

  • Sapphire HD4870 Toxic 845/1066

To overclock the Sapphire HD4870 Toxic, I started off by raising the GPU speed a little at a time and testing to make sure it was stable. If it was, I added some more to it until I could not run any stability tests. Once I hit the wall for the GPU speed, I used the same method for the memory until I hit the maxumim stable. The walls I hit were 845 on the core and 1066 on the memory. For a card that was already overclocked, the additional speed gained was very nice. Also while testing the card overclocked, the temperatures remained around 67C degrees with the fan speed controlled by the Catalyst Control Center, which is fairly cool for an HD4870 that is running even at stock speeds. By bumping up the fan speeds, the temperatures plummet down into the 50C range at 55C. But when the fan speeds are increased there is the noise penalty with the typical ATI fan noise with the fan spinning at almost 4000 RPM. Controlled by the CCC the fan speeds remain in the 500 to 1500 RPM.
