![]() ![]() Those readers who follow our content regularly will remember that we reviewed the Sapphire HD6870 Toxic Edition last week. The MSI R6870 HAWK is an extremely capable card and we think the Twin Frozr III cooler is quite possibly the best on the market. KitGuru has also tested the R6870 Hawk with TessMark and ShaderToyMark. The R6870 Hawk is priced at around 250 euros. One another interesting feature of this HD 6870 is the OCP unlocker: the OCP, or Over Current Protection, can be disabled which offers more headroom for overclocking… I think I will shortly test the Return To Idle of some cards because 20 seconds sound fast but actually I don’t have reference values… This is a good indication of how quickly a heatsink can dissipate heat. The Twin Frozr III is able to return to idle temperature in around 20 seconds. KitGuru has also introduced a new test called Return To Idle (I like this name!): In my review of SAPPHIRE HD 6870 with reference cooler and clock speeds, I found that the max GPU temperature under FurMark 1.8.2 was 85☌ for a GPU core clock of 900MHz and 86☌ at 940MHz.Īccording to KitGuru tests, under FurMark, the R6870 Hawk does not exceed 65☌ which is 20☌ lower than reference cooler. This card comes with a 10-phase VRM (8 for the GPU and the others for memory and PLL), voltage check points, the new Twin Frozr III VGA cooler and a factory-overclocked GPU (Barts XT) at 930MHz (ref: 900MHz). MSI has released a new Radeon HD 6870 for overclockers: the R6870 Hawk.
