GeForce GTX 860M vs Radeon HD 5450

Intro

The GeForce GTX 860M comes with a GPU clock speed of 797 MHz, and the 4096 MB of GDDR5 memory is set to run at 1000 MHz through a 128-bit bus. It also features 1152 SPUs, 96 TAUs, and 16 ROPs.

Compare those specs to the Radeon HD 5450, which has GPU clock speed of 650 MHz, and 512 MB of DDR3 RAM set to run at 800 MHz through a 64-bit bus. It also features 80(16x5) Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a 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 clock speed of the card. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
