GeForce GT 130 vs Radeon R7 M260

Intro

Compare those specifications to the Radeon R7 M260, which has core speeds of 715 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 M260 should in theory be much superior to the GeForce GT 130 in general. (explain)

Radeon R7 M260		16000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 4000 (33%)

Texel Rate

The Radeon R7 M260 is a lot (more or less 43%) better at AF than the GeForce GT 130. (explain)

Radeon R7 M260		17160 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 5160 (43%)

Pixel Rate

The GeForce GT 130 will be quite a bit (approximately 40%) better at FSAA than the Radeon R7 M260, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GT 130		8000 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 2280 (40%)

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 (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once 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 high 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 of the card by the core speed of the chip. The better the texel rate, the better the video 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
