GeForce GT 340 1GB vs GeForce GTX 580 3GB
Intro
The GeForce GT 340 1GB makes use of a 40 nm design. nVidia has set the core frequency at 550 MHz. The GDDR5 memory works at a frequency of 850 MHz on this model. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.Compare all of that to the GeForce GTX 580 3GB, which features GPU clock speed of 772 MHz, and 3072 MB of GDDR5 RAM set to run at 1002 MHz through a 384-bit bus. It also is made up of 512 SPUs, 64 TAUs, and 48 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has 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, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
