AMD has now released their HD 7750 line of cards and this is the first one that we've had in our lab. These cards feature an 800MHz GPU clock and 512 Stream Processing Units or shaders. They also feature an 1125MHz memory clock with an effective memory clock of 4.5Gbps. They come with a full gig of GDDR5 memory and 16 Raster Operators.
These cards also feature support for the new PCIe 3.0 bus interface. This will become fully enabled once Intel's next generation of processors hit the market. These new processors will enable PCIe 3.0 support for these new cards. These also feature support for the new 4k video resolution once these displays are made available. Keep in mind though that with only a gig of video memory there will be some performance issues when using this high of a resolution. Your video memory is what buffers your displayed frames and the more memory you have, the better your performance will be.
Microsoft's Direct X 11 is also fully supported by these new cards and that means hardware tessellation support. This technology allows for enhanced geometry rendering of textures and landscapes. If you haven't seen this yet it's truly an amazing technology that really enhances the realism in a 3D gaming environment. These cards are also compatible with AMD's Eyefinity technology. This technology provides for multi-monitor support. These cards will also be limited for use of this technology due to their lack of dedicated video memory. This is a great feature for those that need the extra visual real estate.
