GeForce GT 210 vs Radeon R9 270

Intro

Compare all that to the Radeon R9 270, which features GPU core speed of 900 MHz, and 2048 MB of GDDR5 memory set to run at 1400 MHz through a 256-bit bus. It also is comprised of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

GeForce GT 210		12800 MB/sec
	Difference: 166400 (1300%)

Texel Rate

The Radeon R9 270 is quite a bit (more or less 1428%) faster with regards to AF than the GeForce GT 210. (explain)

Radeon R9 270		72000 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 67288 (1428%)

Pixel Rate

The Radeon R9 270 should be a lot (approximately 1122%) more effective at AA than the GeForce GT 210, and will be able to handle higher screen resolutions more effectively. (explain)

Radeon R9 270		28800 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 26444 (1122%)

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 maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 get to the maximum fill rate.
