AMD "Hawaii" Based Dual-GPU Graphics Card Around the Corner?
AMD started sending editors / VGA reviewers of some leading tech websites envelopes labeled "Top Secret." In it, are Polaroid-sized photos of the editors. In each photo, there are two pictures of the same editor, with a cryptic handwritten note that reads "Wouldn't you agree that two is better than one?" Two such pictures are posted below, by our friends from AnandTech and PC Perspective. This stunt is leading some to believe that AMD is ready with a dual-GPU graphics card based on its "Hawaii" silicon, given that it began guerrilla-marketing it.
Given how power-hungry a single-GPU Radeon R9 290X is, the only way AMD can build a dual-GPU card that doesn't outdo your hairdryer in power consumption (and possibly noise), is by toning each GPU down in specifications. The "Hawaii" silicon could either be configured similar to the R9 290 (i.e. 2,560 SPs, 160 TMUs), with lower clock speeds; or tone it down even further, by disabling more GCN compute units. There's also the option of narrowing down the memory bus and ROP count.
