GeForce GT 450 (OEM) vs GeForce GTX 260 Core 216

Intro

The GeForce GT 450 (OEM) comes with clock speeds of 790 MHz on the GPU, and 1000 MHz on the 1536 MB of GDDR5 RAM. It features 144 SPUs along with 24 Texture Address Units and 24 Rasterization Operator Units.

Compare all that to the GeForce GTX 260 Core 216, which has a core clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit bus, and uses a 65 nm design. It is comprised of 216 SPUs, 72 Texture Address Units, and 28 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling 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 record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
