ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. It is measured in millions of texels in a second. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF).
This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. It especially helps with AA, HDR and high resolutions.

The higher the memory bandwidth, the faster the card will be in general. Passmark, SPECviewperf 12, 3Dmark and other. Compare graphics card gaming performance. In the case of DDR memory, it should be multiplied by 2 once again. GPU Comparison Specs & Benchmarks ATI Radeon HD 3870 vs AMD Radeon R7 240. Based on 36,393 user benchmarks for the AMD R7 240 and the ATI Radeon HD 3870, we rank them both on effective speed and value for money against the best 636 GPUs. Specifications Core Configuration Memory Configuration Additional details Raw Performance comparison Pixel Rate Radeon HD 3870 X2 26.40 GP/s Radeon R7 240 (HD 8570 rebrand) 5. The ATI Mobility Radeon HD 3870-X2 Crossfire Disabled averaged 97.0 lower than the peak scores attained by the group leaders. It is calculated by multiplying the bus width by its memory speed. The Radeon HD 3870 X2 is the better performing card based on the synthetic benchmarks used (1 benchmarks). Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second.
