GeForce GT 340 1GB vs GeForce GTX 460 2GB
Intro
The GeForce GT 340 1GB has a clock speed of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It features 96 SPUs, 32 TAUs, and 8 ROPs.Compare all that to the GeForce GTX 460 2GB, which has GPU core speed of 675 MHz, and 2048 MB of GDDR5 RAM running at 900 MHz through a 256-bit bus. It also features 336 Stream Processors, 56 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the 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 number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
