GeForce GTX 560 Ti vs GeForce GTX 650 Ti

Intro

The GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has set the core frequency at 822 MHz. The GDDR5 memory is set to run at a speed of 1002 MHz on this specific model. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Compare those specs to the GeForce GTX 650 Ti, which uses a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 memory works at a speed of 1350 MHz on this model. It features 768 SPUs along with 64 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
