GeForce GT 210 vs Radeon HD 6990

Intro

Compare that to the Radeon HD 6990, which makes use of a 40 nm design. AMD has clocked the core frequency at 830 MHz. The GDDR5 memory is set to run at a speed of 1250 MHz on this particular card. It features 1536 SPUs as well as 96 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
Radeon HD 6990		375 Watts
	Difference: 344 Watts (1110%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6990 should be 2400% faster than the GeForce GT 210 overall, because of its higher bandwidth. (explain)

Radeon HD 6990		320000 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 307200 (2400%)

Texel Rate

The Radeon HD 6990 will be quite a bit (approximately 3282%) more effective at texture filtering than the GeForce GT 210. (explain)

Radeon HD 6990		159360 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 154648 (3282%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6990 is a better choice, and very much so. (explain)

Radeon HD 6990		53120 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 50764 (2155%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
