GeForce GT 340 1GB vs Radeon HD 4550 256MB
Intro
The GeForce GT 340 1GB makes use of a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 memory runs at a frequency of 850 MHz on this particular card. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.Compare all of that to the Radeon HD 4550 256MB, which has clock speeds of 600 MHz on the GPU, and 800 MHz on the 256 MB of DDR3 memory. It features 80(16x5) SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
