Features Key features of the Radeon HD 8670 vs GeForce GTX 260
memory bandwidth Rate at which data can be read from or stored in onboard memory
Radeon HD 8670 | by Anand-Lal-Shimpi (Jun, 2013)As memory bandwidth becomes the ultimate bounding condition, the gap between Richland and Haswell shrinks considerably.
pixel rate Number of pixels a graphics card can render to the screen every second
Radeon HD 8670 | by Anand-Lal-Shimpi (Jun, 2013)Here the Radeon HD 8670D holds a 50% performance advantage over Intel's HD 4600 graphics.
texture rate Speed at which a graphics card can perform texture mapping
Radeon HD 8670 | by Anand-Lal-Shimpi (Jun, 2013)While there isn't a substantial increase in GPU performance between Richland and Trinity, AMD's GPU performance lead over Ivy Bridge was big enough to withstand Haswell's arrival.
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
GeForce GTX 260 | by techPowerUp! (Sep, 2008)Also it should be noted that this 216 shader GPU will not completely replace the GTX 260 with 192 shaders.
texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes
