GeForce GTX 285 2GB vs Radeon HD 6450 (OEM)
Intro
The GeForce GTX 285 2GB comes with core speeds of 648 MHz on the GPU, and 1242 MHz on the 2048 MB of GDDR3 RAM. It features 240 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.Compare those specs to the Radeon HD 6450 (OEM), which features GPU core speed of 625 MHz, and 512 MB of GDDR3 RAM running at 800 MHz through a 64-bit bus. It also is comprised of 160 Stream Processors, 8 TAUs, and 4 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a 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 - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
