![]() The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate. ![]() Compare that to the Radeon R7 M265, which features GPU core speed of 725 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 128. It features 1152 SPUs, 96 TAUs, and 16 ROPs. It also features a 128-bit bus, and uses a 28 nm design. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The GeForce GTX 860M comes with a core clock frequency of 797 MHz and a GDDR5 memory frequency of 1000 MHz. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. ![]() It is measured in millions of texels applied per second. Just like the older Radeon HD 8700M and 8600M series, it is based on the Mars chip (28nm GCN architecture) with. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). The AMD Radeon R7 M260 is a lower mid-range DirectX 11 graphics card for laptops. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. It especially helps with anti-aliasing, HDR and higher screen resolutions. The higher the card's memory bandwidth, the better the card will be in general. ![]() In the case of DDR type memory, it must be multiplied by 2 once again. 0x1002, 0圆613, Low Radeon R7 240/340 0x1002, 0x990B, Low Radeon HD 8650G. The number is worked out by multiplying the bus width by the speed of its memory. Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. ![]()
