The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate. GeForce GTX 770 graphics cards have NVIDIA GPU Boost 2.0 and FXAA & TXAA anti-aliasing technologies that improve your graphics without impacting your game speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. It is measured in millions of texels applied in one second. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). This figure 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 number of texture map elements (texels) that can be processed per second. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. and a link to the respective comparisons for each of the graphics cards. The better the bandwidth is, the faster the card will be in general. If it uses DDR memory, the result should be multiplied by 2 once again. It is calculated by multiplying the card's interface width by its memory clock speed. General performance parameters such as number of shaders, GPU core base clock and boost. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. GTX 780 has 375 better value for money than GTX 770. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). Compare that to the Geforce GTX 770, which features a GPU core clock speed of 1046 MHz, and 2048 MB of GDDR5 memory running at 1753 MHz through a 256-bit. It also is comprised of 960 SPUs, 80 TAUs, and 24 ROPs. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. The GeForce GTX 660 has a GPU core clock speed of 980 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1502 MHz through a 192-bit bus. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. It is measured in millions of texels applied in a second. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It also features 1536 Stream Processors, 128 TAUs, and 32 ROPs. This is calculated by multiplying the total texture units by the core clock speed of the chip. The Geforce GTX 770 has a GPU core clock speed of 1046 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1753 MHz through a 256-bit bus. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. ![]() It especially helps with anti-aliasing, High Dynamic Range and high resolutions. The better the card's memory bandwidth, the better the card will be in general.

If it uses DDR type memory, the result should be multiplied by 2 once again. It is calculated by multiplying the interface width by the speed of its memory. Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface within a second.
