GeForce GT 210 vs Radeon HD 7950 3GB

Intro

Compare all that to the Radeon HD 7950 3GB, which uses a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1250 MHz on this card. It features 1792 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

GeForce GT 210		12800 MB/sec
	Difference: 227200 (1775%)

Texel Rate

The Radeon HD 7950 3GB should be quite a bit (about 1802%) better at AF than the GeForce GT 210. (explain)

Radeon HD 7950 3GB		89600 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 84888 (1802%)

Pixel Rate

The Radeon HD 7950 3GB is a lot (approximately 987%) more effective at anti-aliasing than the GeForce GT 210, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon HD 7950 3GB		25600 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 23244 (987%)

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 (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be 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 better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
