AMD recently announced their Radeon R9 285 graphics card, this was their first major graphics card announcement since the R9 295X2 back in April. Looking at the naming of the card we expect it to be a replacement for the R9 280, but is it really? It has the same number of shaders, TMUs, and ROPs as the R9 280, but has a narrower memory bus at 256bit (vs 364bit of R9 280X) and less VRAM (2 GB vs 3 GB), although that memory is clocked higher (5.5 GHz vs 5.0 GHz). Looking at the specifications you may be wondering what what is the point? Well unlike the R9 280 which is built on AMD’s Tahiti silicon, the R9 285 is built on the brand new Tonga silicon. While it is still based on the same 28 nm process Tonga is said to be more efficient and also adds many of the features that we saw on the Hawaii silicon like XDMA CrossFire (no more CrossFire connectors), TrueAudio DSP, and the ability to connect 4 displays using all output connectors on the card. Today we are taking a look at Sapphire’s Radeon R9 285 Dual-X OC version of the card. It will feature a slight overclock on the core clock (965 MHz vs 918 MHz) and the memory (1400 MHz vs 1375 MHz). It will also have Sapphire’s Dual-X cooling solution which seems to be extremely quiet. Let’s jump in and see what this card can do.
