GeForce 9800 GTX+ vs GeForce GT 450 (OEM)
Intro
The GeForce 9800 GTX+ makes use of a 55 nm design. nVidia has clocked the core speed at 738 MHz. The GDDR3 RAM is set to run at a frequency of 1100 MHz on this specific card. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.Compare those specifications to the GeForce GT 450 (OEM), which has core 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 TAUs and 24 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video 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 number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
