GeForce GT 130 vs Radeon R9 M280X

Intro

Compare those specifications to the Radeon R9 M280X, which features core clock speeds of 900 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon R9 M280X should in theory be much better than the GeForce GT 130 in general. (explain)

Radeon R9 M280X		88000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 76000 (633%)

Texel Rate

The Radeon R9 M280X should be quite a bit (about 320%) better at texture filtering than the GeForce GT 130. (explain)

Radeon R9 M280X		50400 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 38400 (320%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M280X is the winner, by a large margin. (explain)

Radeon R9 M280X		14400 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 6400 (80%)

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 max amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 bandwidth is, the lower the potential to get to the max fill rate.
