GeForce 9600 GT 512MB vs Radeon HD 6670 (OEM) 1GB

Intro

Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. ATi has clocked the core frequency at 800 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this specific model. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Radeon HD 6670 (OEM) 1GB		64000 MB/sec
GeForce 9600 GT 512MB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce 9600 GT 512MB is a little bit (approximately 8%) better at anisotropic filtering than the Radeon HD 6670 (OEM) 1GB. (explain)

GeForce 9600 GT 512MB		20800 Mtexels/sec
Radeon HD 6670 (OEM) 1GB		19200 Mtexels/sec
	Difference: 1600 (8%)

Pixel Rate

The GeForce 9600 GT 512MB will be much (more or less 63%) faster with regards to FSAA than the Radeon HD 6670 (OEM) 1GB, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce 9600 GT 512MB		10400 Mpixels/sec
Radeon HD 6670 (OEM) 1GB		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 information (counted in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
