GeForce GT 130 vs Radeon R9 M280X

Intro

Compare all of that to the Radeon R9 M280X, which uses a 28 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 RAM runs at a frequency of 1375 MHz on this particular model. It features 896 SPUs as well as 56 Texture Address Units 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 theoretically be a lot 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 will be much (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 using a high screen resolution is important to you, then the Radeon R9 M280X is the winner, and very much so. (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 largest amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
