GeForce 9800 GT 1GB vs Radeon HD 6570 (OEM) 1GB
Intro
The GeForce 9800 GT 1GB comes with a clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit memory bus, and makes use of a 65/55 nm design. It is comprised of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 6570 (OEM) 1GB, which makes use of a 40 nm design. AMD has set the core speed at 650 MHz. The GDDR3 RAM works at a speed of 900 MHz on this particular card. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
