GeForce GT 210 vs Radeon HD 4670 512MB

Intro

Compare all of that to the Radeon HD 4670 512MB, which makes use of a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 RAM is set to run at a speed of 1000 MHz on this particular model. It features 320(64x5) SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.

GeForce GT 210		12800 MB/sec
	Difference: 19200 (150%)

Texel Rate

The Radeon HD 4670 512MB should be quite a bit (approximately 409%) more effective at texture filtering than the GeForce GT 210. (explain)

Radeon HD 4670 512MB		24000 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 19288 (409%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 4670 512MB is the winner, by a large margin. (explain)

Radeon HD 4670 512MB		6000 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 3644 (155%)

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 largest amount of information (in units of MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
