GeForce GT 440 3GB vs Radeon R9 380 2G
Intro
The GeForce GT 440 3GB comes with a clock speed of 594 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 192-bit memory bus, and uses a 40 nm design. It features 144 SPUs, 24 TAUs, and 24 Raster Operation Units.Compare all that to the Radeon R9 380 2G, which comes with a core clock speed of 970 MHz and a GDDR5 memory speed of 1425 MHz. It also makes use of a 256-bit bus, and uses a 28 nm design. It is comprised of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
