GeForce 9800 GT 1GB vs GeForce GTX 570

Intro

Compare those specifications to the GeForce GTX 570, which features a core clock frequency of 732 MHz and a GDDR5 memory frequency of 950 MHz. It also uses a 320-bit memory bus, and uses a 40 nm design. It is made up of 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.

GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 10320 (31%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 570 is a better choice, by far. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 19680 (205%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
