GeForce GTX 285 1GB vs Radeon HD 6450 (OEM)
Intro
The GeForce GTX 285 1GB features a clock frequency of 648 MHz and a GDDR3 memory frequency of 1242 MHz. It also uses a 512-bit bus, and makes use of a 55 nm design. It is made up of 240 SPUs, 80 Texture Address Units, and 32 ROPs.Compare those specs to the Radeon HD 6450 (OEM), which features a clock speed of 625 MHz and a GDDR3 memory speed of 800 MHz. It also uses a 64-bit bus, and makes use of a 40 nm design. It is made up of 160 SPUs, 8 TAUs, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
