by Anand-Lal-Shimpi (Jan, 2013)NVIDIA did hint that the pixel shader design was somehow more efficient than what was used in Tegra 3.
by Josh-Walrath (Feb, 2013)The core speed is increased to 672 MHz, well up from the 520 MHz in Tegra 3 (8 pixel and 4 vertex shaders).
Features Key features of the Radeon R9 290X Battlefield 4
pixel rate Number of pixels a graphics card can render to the screen every second
floating point performance How fast the gpu can crunch numbers
shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading
texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes
render output processors GPU commponents responsible for transform pixels as they flow between memory buffers
compute units Discrete cores within the GPU

There is not much to see in the release notes, although you can now enjoy Deus Ex in glorious 3D vision assuming you have the monitor and glasses.

The main advantage of the standard will be extra bandwidth, about double that of PCIe 3.0, not easing cable management or making it easier to design a graphics card (by making it harder to design a motherboard).
The slot will still only provide 75W of power; any other power will still need to come from external connectors.

This is a good range to be in for a G-Sync monitor, as the single-card machine doesn't need to deal with multi-GPU issues, like pacing and driver support.
The lowest quality version was almost completely devoid of shadowing and its windows would not even draw.

Last is the SEA HAWK X with a much more impressive overclock which you can see in the chart below.
All models have three DisplayPorts 1.4 which is blessing for those with multiple monitors, in addition is an HDMI 2.0 port and DVI.
