GeForce GTX 570 vs GeForce GTX 650 Ti


Intro

The GeForce GTX 570 uses a 40 nm design. nVidia has set the core speed at 732 MHz. The GDDR5 memory works at a speed of 950 MHz on this card. It features 480 SPUs along with 60 Texture Address Units and 40 Rasterization Operator Units.

Compare all that to the GeForce GTX 650 Ti, which comes with a GPU core clock speed of 928 MHz, and 1024 MB of GDDR5 memory running at 1350 MHz through a 128-bit bus. It also is comprised of 768 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high 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 number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 potential to get to the max fill rate.
