GeForce 9800 GTX+ vs Radeon HD 6670 (OEM)

Intro

Compare those specifications to the Radeon HD 6670 (OEM), which has core speeds of 800 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Radeon HD 6670 (OEM)		64000 MB/sec
	Difference: 6400 (10%)

Texel Rate

The GeForce 9800 GTX+ will be quite a bit (more or less 146%) faster with regards to AF than the Radeon HD 6670 (OEM). (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon HD 6670 (OEM)		19200 Mtexels/sec
	Difference: 28032 (146%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 9800 GTX+ is a better choice, by far. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
Radeon HD 6670 (OEM)		6400 Mpixels/sec

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
