GeForce GT 340 1GB vs GeForce GT 450 (OEM)
Intro
The GeForce GT 340 1GB comes with clock speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.Compare all that to the GeForce GT 450 (OEM), which has a core clock speed of 790 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 192-bit memory bus, and uses a 40 nm design. It features 144 SPUs, 24 TAUs, and 24 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
