GeForce 9600 GSO 512MB vs Radeon HD 6670 (OEM)

Intro

Compare those specifications to the Radeon HD 6670 (OEM), which has GPU core speed of 800 MHz, and 512 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 480 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Radeon HD 6670 (OEM)		64000 MB/sec
GeForce 9600 GSO 512MB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce 9600 GSO 512MB should be quite a bit (approximately 63%) more effective at AF than the Radeon HD 6670 (OEM). (explain)

GeForce 9600 GSO 512MB		31200 Mtexels/sec
Radeon HD 6670 (OEM)		19200 Mtexels/sec
	Difference: 12000 (63%)

Pixel Rate

The GeForce 9600 GSO 512MB is much (more or less 63%) faster with regards to anti-aliasing than the Radeon HD 6670 (OEM), and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 9600 GSO 512MB		10400 Mpixels/sec
Radeon HD 6670 (OEM)		6400 Mpixels/sec
	Difference: 4000 (63%)

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 maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
