GeForce GT 450 (OEM) vs Radeon HD 3650 256MB
Intro
The GeForce GT 450 (OEM) makes use of a 40 nm design. nVidia has clocked the core frequency at 790 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular model. It features 144 SPUs as well as 24 Texture Address Units and 24 ROPs.Compare all of that to the Radeon HD 3650 256MB, which has core 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 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses 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 per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, 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 number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
