Heaven is regarded to be one of the most intensive Benchmarking utilities about at the moment along with the likes of 3DMark. It makes use of highly comprehensive tessellation technology, advanced SSAO (screen-space ambient occlusion) and a highly defined light algorithm to produce ever changing light conditions amongst other items.
Heaven show that this card is a very close offering compared to the one from Sapphire which has a 45MHz faster core clock speed. We do see the card dropping one or two frames over the slightly faster card.
How can the HD7870 been out performed by a HD7790(own that one) that looks wrong!?
agreed. thats the problem with pulling results from an aged database where driver versions used for graphics card testing aren’t consistent. the 7870 was probably tested nearly a year ago with old drivers. if it were to be tested with the same drivers as the ones the 7790 are using all the results would be very different indeed
