GeForce GTS 450 1GB vs Radeon HD 6450 (OEM)
Intro
The GeForce GTS 450 1GB uses a 40 nm design. nVidia has clocked the core frequency at 783 MHz. The GDDR5 RAM works at a frequency of 902 MHz on this particular card. It features 192 SPUs along with 32 Texture Address Units and 16 ROPs.Compare those specifications to the Radeon HD 6450 (OEM), which comes with core speeds of 625 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 160 SPUs along with 8 TAUs and 4 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen 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 texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
