MSI Launches R4600 HDMI series Of GPUs
Strangely, MSI doesn't bother sharing other important tidbits like clock / memory speeds or anything like that, though it does make clear that 7.1-channel audio from Blu-ray Discs is possible. Also, the card is capable of handling 1080p content, and it also supports Unified Video Decoder (UVD) 2.0, so that the CPU is not decoding the entire digital stream itself. Of note, these cards both use a maximum of 75 watts of power and thus do not require an extra PCIe 12v power supply. Not surprisingly, they're also small enough that they won't bump into any other nearby PCIe slots.
We're hoping to here more about pricing, availability and full specifications soon.
