GeForce 9500 GT 1GB GDDR3 vs Radeon HD 6450 (OEM) 1GB

Intro

The GeForce 9500 GT 1GB GDDR3 comes with core clock speeds of 550 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR3 RAM. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Compare that to the Radeon HD 6450 (OEM) 1GB, which has GPU clock speed of 750 MHz, and 1024 MB of GDDR5 memory set to run at 900 MHz through a 64-bit bus. It also is comprised of 160 SPUs, 8 TAUs, and 4 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a 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 sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
