ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. The Toxic Vapor-X cooler offers cooling comparable to dual-slot solutions through vapor. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The Sapphire Radeon HD 3870 Toxic 512MB itself is a svelt single slot card designed around ATI's RV670 GPU. It is measured in millions of texels processed per second. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. It especially helps with AA, High Dynamic Range and higher screen resolutions. The better the card's memory bandwidth, the better the card will be in general.
In the case of DDR RAM, it should be multiplied by 2 once again. It's calculated by multiplying the bus width by its memory speed. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. It is measured in millions of texels applied per second.

This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. We earn an affiilate comission through Amazon Associate links. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. HIS Radeon HD 3870 512MB IceQ3 (H387QS512GNP). It especially helps with AA, HDR and higher screen resolutions. The higher the memory bandwidth, the better the card will be in general. If the card has DDR type memory, it must be multiplied by 2 once again. The number is calculated by multiplying the card's interface width by its memory speed. Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second.
