GeForce GT 450 (OEM) vs Radeon HD 3650 256MB
Intro
The GeForce GT 450 (OEM) has a core clock frequency of 790 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 192-bit bus, and makes use of a 40 nm design. It is made up of 144 SPUs, 24 Texture Address Units, and 24 Raster Operation Units.Compare all of that to the Radeon HD 3650 256MB, which has clock speeds of 725 MHz on the GPU, and 800 MHz on the 256 MB of DDR2 memory. It features 120(24x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 can be processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
