GeForce GTS 450 1GB vs Radeon HD 5750 1GB
Intro
The GeForce GTS 450 1GB comes with a core clock speed of 783 MHz and a GDDR5 memory speed of 902 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is comprised of 192 SPUs, 32 Texture Address Units, and 16 ROPs.Compare all that to the Radeon HD 5750 1GB, which uses a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory works at a speed of 1150 MHz on this card. It features 720(144x5) SPUs as well as 36 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could 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 Raster Operations Pipelines by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
