GeForce GT 450 (OEM) vs GeForce GTX 460 2GB
Intro
The GeForce GT 450 (OEM) features a GPU core speed of 790 MHz, and the 1536 MB of GDDR5 RAM runs at 1000 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 TAUs, and 24 Raster Operation Units.Compare those specs to the GeForce GTX 460 2GB, which makes use of a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 memory runs at a frequency of 900 MHz on this particular model. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured 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 the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
