GeForce GT 130 vs Radeon R9 270

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
Radeon R9 270		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

In theory, the Radeon R9 270 should perform quite a bit faster than the GeForce GT 130 in general. (explain)

Radeon R9 270		179200 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 167200 (1393%)

Texel Rate

The Radeon R9 270 should be quite a bit (more or less 500%) better at anisotropic filtering than the GeForce GT 130. (explain)

Radeon R9 270		72000 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 60000 (500%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 270 is superior to the GeForce GT 130, and very much so. (explain)

Radeon R9 270		28800 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 20800 (260%)

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 largest amount of data (counted in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
