GeForce 9800 GTX+ vs Radeon HD 6570 (OEM) 2GB

Intro

The GeForce 9800 GTX+ comes with a GPU core clock speed of 738 MHz, and the 512 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Compare those specs to the Radeon HD 6570 (OEM) 2GB, which uses a 40 nm design. AMD has set the core speed at 650 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this model. It features 480 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR memory, 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
