GeForce GT 210 vs Radeon HD 7850

Intro

Compare all of that to the Radeon HD 7850, which makes use of a 28 nm design. AMD has clocked the core speed at 860 MHz. The GDDR5 RAM runs at a frequency of 1200 MHz on this particular model. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
Radeon HD 7850		130 Watts
	Difference: 99 Watts (319%)

Memory Bandwidth

In theory, the Radeon HD 7850 will be 1100% quicker than the GeForce GT 210 overall, because of its higher data rate. (explain)

Radeon HD 7850		153600 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 140800 (1100%)

Texel Rate

The Radeon HD 7850 will be much (approximately 1068%) better at AF than the GeForce GT 210. (explain)

Radeon HD 7850		55040 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 50328 (1068%)

Pixel Rate

The Radeon HD 7850 should be quite a bit (approximately 1068%) better at AA than the GeForce GT 210, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 7850		27520 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 25164 (1068%)

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 max amount of data (in units of MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
