Phoronix AMD Radeon HD 4870 X2 On Linux
While details on AMD’s high-end ATI Radeon HD 4870 X2 graphics card began surfacing last month, today this dual-GPU graphics card has formally launched and will begin shipping to retailers. The good news this time around is that this graphics card will actually be something worth looking at under Linux now that there’s the needed CrossFire support on the horizon. We’re not yet permitted to publish the Linux CrossFire benchmarks, but today we have a few pieces of information to share about the Radeon HD 4870 X2 on Linux.
To start with, the Radeon HD 4870 X2 graphics card we have had our hands on for the past couple of days is the VisionTek Radeon HD 4870 X2 with 2GB of GDDR5 memory. The Radeon HD 4870 X2 (codenamed the “R700″) is based around two RV770 graphics processors and is connected via a PCI Express bridge and CrossFire X SidePort. Over the Radeon HD 3870 X2 are the benefits of PCI Express 2.0, an increased number of stream processing units, Unified Video Decoder 2, PowerPlay+, and increased efficiency. The two GPU cores operate at 750MHz and the 2GB of GDDR5 memory (1GB for each GPU) runs at 900MHz.
