The GV-R687OC-1GD from GBT Technology Co Ltd
Faster clocks, double the transistor density of earlier 40 nm technology. 40nm technology helped make HD6870 series products the most advanced GPUs ever highest clocks speeds, incredible feature integration, full performance and precision all the time, and ability to take advantage of future, higher-speed memories. AvivoHD could provide vibrant high fidelity, flawlessly smooth next-generation video playback. AvivoHD technology easily allows your PCs to become digital home media center by its compelling video pipeline design that comprises the high definition video hardware acceleration, including H.264 and WMV9. Shader Model 5.0 adds support for indexed temporaries which can be quite useful for certain tasks. Regular direct temporary access is preferable is most cases. One reason is that indexed temporaries are hard to optimize. The shader optimizer may not be able to identify optimizations across indexed accesses that could otherwise have been detected. Furthermore, indexed temporaries tend to increase register pressure a lot. An ordinary shader that contains for instance a few dozen variables will seldom consume a few dozen temporaries in the end but is likely to be optimized down to a handful depending on what the shader does. This is because the shader optimizer can easily track all variables and reuse registers. This is typically not possible for indexed temporaries, thus the register pressure of the shader may increase dramatically. This could be detrimental to performance as it reduces the hardware's ability to hide latencies. Give the whole of Earth a promise that the products do not contain any of the restricted substances in concentrations and applications banned by the RoHS Directive, and are capable of being worked on at the higher temperatures required for lead free solder. One Earth and Gigabyte cares!
