Compare any two graphics cards:

GeForce GT 340 1GB vs Radeon R7 M260X

Intro

The GeForce GT 340 1GB features a clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Compare those specs to the Radeon R7 M260X, which comes with clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 memory. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
