GeForce GTS 250 1GB vs Radeon HD 6570 (OEM) 2GB
Intro
The GeForce GTS 250 1GB makes use of a 65/55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 memory is set to run at a speed of 1100 MHz on this model. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.Compare all of that to the Radeon HD 6570 (OEM) 2GB, which has a core clock frequency of 650 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It features 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, 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 maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
