GeForce 9800 GT 512MB vs Radeon HD 6570 (OEM) 2GB

Intro

The GeForce 9800 GT 512MB features a GPU core speed of 600 MHz, and the 512 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also is comprised of 112 SPUs, 56 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which features a core clock frequency of 650 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Radeon HD 6570 (OEM) 2GB 64000 MB/sec
GeForce 9800 GT 512MB 57600 MB/sec
Difference: 6400 (11%)

Texel Rate

The GeForce 9800 GT 512MB should be quite a bit (approximately 115%) more effective at texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)

GeForce 9800 GT 512MB 33600 Mtexels/sec
Radeon HD 6570 (OEM) 2GB 15600 Mtexels/sec
Difference: 18000 (115%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9800 GT 512MB is superior to the Radeon HD 6570 (OEM) 2GB, and very much so. (explain)

GeForce 9800 GT 512MB 9600 Mpixels/sec
Radeon HD 6570 (OEM) 2GB 5200 Mpixels/sec
Difference: 4400 (85%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. 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 ability to reach the maximum fill rate.
