GeForce GTX 860M vs Radeon HD 4730

Intro

The GeForce GTX 860M has a GPU core speed of 797 MHz, and the 4096 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also features 1152 SPUs, 96 TAUs, and 16 ROPs.

Compare those specifications to the Radeon HD 4730, which has a core clock speed of 700 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 128-bit bus, and uses a 55 nm design. It features 640(128x5) SPUs, 32 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount 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 worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
