GeForce GTS 450 1GB vs Radeon HD 6570 (OEM) 2GB
Intro
The GeForce GTS 450 1GB makes use of a 40 nm design. nVidia has set the core speed at 783 MHz. The GDDR5 RAM is set to run at a frequency of 902 MHz on this model. It features 192 SPUs as well as 32 Texture Address Units and 16 ROPs.Compare all that to the Radeon HD 6570 (OEM) 2GB, which has a core clock speed of 650 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it should 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 anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
