GeForce GT 240 GDDR5 vs Radeon R9 380 2G

Intro

The GeForce GT 240 GDDR5 uses a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this specific model. It features 96 SPUs as well as 32 Texture Address Units and 8 ROPs.

Compare that to the Radeon R9 380 2G, which has a core clock frequency of 970 MHz and a GDDR5 memory frequency of 1425 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It features 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant 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.
