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 actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate. The Radeon HD 3870 X2 is the better performing card based on the synthetic benchmarks used (1 benchmarks).

ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. Title Bitness Released File Size More AMD Catalyst 15.9 Proprietary Ubuntu 14.04 x8664 Catalyst Control Center: 64-Bit: : 6.38 MB: Download AMD Catalyst 15.9 Proprietary Ubuntu 14. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Difference: 6560 (112) Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. It is measured in millions of texels applied in a second. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). This is worked out by multiplying the total amount of texture units by the core clock speed of the chip.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. It especially helps with AA, HDR and high resolutions.
The higher the memory bandwidth, the better the card will be in general. If it uses DDR type memory, the result should be multiplied by 2 again. The number is calculated by multiplying the bus width by its memory clock speed. Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second.
