![]() ![]() The 384 shaders can be used with OpenCL 1.2 for general-purpose calculations (as 6 compute units). In older games, however, higher quality settings will be possible. Current and demanding games of 2013/2014 can be played fluently only in low resolutions and detail settings. The performance of the 128 bit Radeon R7 M260 is just slightly below a GeForce 825M, while models using a 64 bit memory interface will be a bit slower. The core is clocked at up to 715 MHz (128 bit version) or 980 MHz (64 bit version) and can access up to 4 GB of DDR3 memory (1000 MHz, 2000 MHz effective). Just like the older Radeon HD 8700M and 8600M series, it is based on the Mars chip (28nm GCN architecture) with 384 shader cores, 24 TMUs and 8 ROPs. ![]() The AMD Radeon R7 M260 is a lower mid-range DirectX 11 graphics card for laptops. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.AMD Radeon R7 M260 ► remove from comparison ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. It is measured in millions of texels applied per second. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. ![]() Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. The better the memory bandwidth, the better the card will be in general. If it uses DDR type RAM, it must be multiplied by 2 again. It is calculated by multiplying the card's interface width by its memory speed. ![]() Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface in a second. ![]()
