GeForce 8800 GT 1GB vs GeForce GT 450 (OEM)
Intro
The GeForce 8800 GT 1GB uses a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this specific card. It features 112 SPUs along with 56 TAUs and 16 ROPs.Compare those specs to the GeForce GT 450 (OEM), which features GPU clock speed of 790 MHz, and 1536 MB of GDDR5 RAM set to run at 1000 MHz through a 192-bit bus. It also features 144 SPUs, 24 TAUs, and 24 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
