GeForce GTX 560 Ti vs Geforce GTX 690

Intro

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

Compare all that to the Geforce GTX 690, which uses a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this particular model. It features 1536 SPUs along with 128 TAUs and 32 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one 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 number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
