GeForce 9600 GT 512MB vs Radeon HD 6850

Intro

The GeForce 9600 GT 512MB has a GPU core clock speed of 650 MHz, and the 512 MB of GDDR3 memory is set to run at 900 MHz through a 256-bit bus. It also is comprised of 64 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon HD 6850, which comes with a core clock speed of 775 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It is made up of 960 SPUs, 48 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 512MB 95 Watts
Radeon HD 6850 127 Watts
Difference: 32 Watts (34%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6850 should be 122% faster than the GeForce 9600 GT 512MB in general, because of its greater data rate. (explain)

Radeon HD 6850 128000 MB/sec
GeForce 9600 GT 512MB 57600 MB/sec
Difference: 70400 (122%)

Texel Rate

The Radeon HD 6850 should be a lot (more or less 79%) faster with regards to AF than the GeForce 9600 GT 512MB. (explain)

Radeon HD 6850 37200 Mtexels/sec
GeForce 9600 GT 512MB 20800 Mtexels/sec
Difference: 16400 (79%)

Pixel Rate

The Radeon HD 6850 will be much (more or less 138%) better at full screen anti-aliasing than the GeForce 9600 GT 512MB, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon HD 6850 24800 Mpixels/sec
GeForce 9600 GT 512MB 10400 Mpixels/sec
Difference: 14400 (138%)

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: Bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, 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 the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
