GV-N450OC-1GI (mouse pad edition)

Faster clocks, double the transistor density of earlier 40 nm technology. 40nm technology helped make GTS 450 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.

Ensure top-notch compatibility and performance for all OpenGL 4.0 application.

World's first DirectX 11 GPU with full Shader Model 4.0 support delivers unparalleled levels of graphics realims and film-quality effects.

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.

PCI Express^® 2.0 –Now you are ready for the most demanding graphics applications thanks to PCI Express^® 2.0 support, which allows up to twice the throughput of current PCI Express^® cards. Doubles the bus standard's bandwidth from 2.5 Gbit/s (PCIe 1.1) to 5 Gbit/sec.
