GeForce GTX 860M vs Radeon HD 4730

Intro

The GeForce GTX 860M makes use of a 28 nm design. nVidia has clocked the core frequency at 797 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular model. It features 1152 SPUs as well as 96 Texture Address Units and 16 Rasterization Operator Units.

Compare that to the Radeon HD 4730, which makes use of a 55 nm design. AMD has set the core speed at 700 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this particular card. It features 640(128x5) SPUs as well as 32 Texture Address Units and 8 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
