GeForce GTS 250 1GB vs GeForce GTX 570

Intro

The GeForce GTS 250 1GB comes with a GPU core speed of 738 MHz, and the 1024 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Compare all of that to the GeForce GTX 570, which uses a 40 nm design. nVidia has clocked the core speed at 732 MHz. The GDDR5 memory is set to run at a frequency of 950 MHz on this specific card. It features 480 SPUs as well as 60 TAUs and 40 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels 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 Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
