GeForce GTX 560 Ti 448 vs Radeon R9 M290X

Intro

The GeForce GTX 560 Ti 448 comes with a clock speed of 732 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 320-bit bus, and makes use of a 40 nm design. It features 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

Compare that to the Radeon R9 M290X, which features clock speeds of 850 MHz on the GPU, and 1200 MHz on the 4096 MB of GDDR5 memory. It features 1280 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
