GeForce GT 340 1GB vs GeForce GTX 460 (OEM)
Intro
The GeForce GT 340 1GB makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this particular card. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.Compare those specs to the GeForce GTX 460 (OEM), which comes with clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs along with 56 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 are processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher 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 most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
