GeForce GT 440 3GB vs Radeon HD 6450 (OEM)
Intro
The GeForce GT 440 3GB uses a 40 nm design. nVidia has set the core frequency at 594 MHz. The GDDR3 memory works at a frequency of 900 MHz on this card. It features 144 SPUs as well as 24 Texture Address Units and 24 ROPs.Compare all of that to the Radeon HD 6450 (OEM), which has a GPU core clock speed of 625 MHz, and 512 MB of GDDR3 RAM running at 800 MHz through a 64-bit bus. It also features 160 Stream Processors, 8 Texture Address Units, and 4 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
