GeForce GT 430 (OEM) vs Radeon R9 380 4G

Intro

The GeForce GT 430 (OEM) comes with a GPU clock speed of 700 MHz, and the 2048 MB of GDDR3 memory is set to run at 900 MHz through a 128-bit bus. It also is made up of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Compare those specifications to the Radeon R9 380 4G, which has a core clock speed of 970 MHz and a GDDR5 memory frequency of 1425 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It is comprised of 1792 SPUs, 112 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
