GeForce GTX 560 vs Radeon HD 7850

Intro

The GeForce GTX 560 uses a 40 nm design. nVidia has set the core speed at 810 MHz. The GDDR5 memory is set to run at a speed of 1001 MHz on this specific model. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon HD 7850, which has a core clock speed of 860 MHz and a GDDR5 memory speed of 1200 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is made up of 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
