GeForce GT 440 3GB vs Radeon R9 380 4G
Intro
The GeForce GT 440 3GB comes with a clock speed of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 192-bit bus, and uses a 40 nm design. It is comprised of 144 SPUs, 24 Texture Address Units, and 24 ROPs.Compare that to the Radeon R9 380 4G, which makes use of a 28 nm design. AMD has set the core frequency at 970 MHz. The GDDR5 RAM works at a speed of 1425 MHz on this model. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.

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