GeForce 9600 GSO 384MB vs Radeon HD 6670 (OEM)

Intro

Compare those specs to the Radeon HD 6670 (OEM), which comes with a clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

In theory, the Radeon HD 6670 (OEM) should perform a lot faster than the GeForce 9600 GSO 384MB in general. (explain)

Radeon HD 6670 (OEM)		64000 MB/sec
GeForce 9600 GSO 384MB		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The GeForce 9600 GSO 384MB is quite a bit (more or less 38%) more effective at AF than the Radeon HD 6670 (OEM). (explain)

GeForce 9600 GSO 384MB		26400 Mtexels/sec
Radeon HD 6670 (OEM)		19200 Mtexels/sec
	Difference: 7200 (38%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 9600 GSO 384MB is superior to the Radeon HD 6670 (OEM), not by a very large margin though. (explain)

GeForce 9600 GSO 384MB		6600 Mpixels/sec
Radeon HD 6670 (OEM)		6400 Mpixels/sec
	Difference: 200 (3%)

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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
