GeForce GT 210 vs Radeon HD 7970

Intro

Compare all of that to the Radeon HD 7970, which uses a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 RAM runs at a frequency of 1375 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
Radeon HD 7970		250 Watts
	Difference: 219 Watts (706%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 7970 should be 1963% faster than the GeForce GT 210 in general, because of its higher data rate. (explain)

Radeon HD 7970		264000 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 251200 (1963%)

Texel Rate

The Radeon HD 7970 will be a lot (about 2413%) faster with regards to AF than the GeForce GT 210. (explain)

Radeon HD 7970		118400 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 113688 (2413%)

Pixel Rate

The Radeon HD 7970 will be much (more or less 1156%) more effective at FSAA than the GeForce GT 210, and also should be capable of handling higher screen resolutions better. (explain)

Radeon HD 7970		29600 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 27244 (1156%)

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 largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core 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 the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
