GeForce GT 130 vs Radeon R9 M385X

Intro

Compare those specifications to the Radeon R9 M385X, which comes with core clock speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X should be 700% quicker than the GeForce GT 130 in general, because of its greater bandwidth. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 84000 (700%)

Texel Rate

The Radeon R9 M385X should be quite a bit (about 413%) better at AF than the GeForce GT 130. (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 49600 (413%)

Pixel Rate

The Radeon R9 M385X will be quite a bit (about 120%) more effective at FSAA than the GeForce GT 130, and should be capable of handling higher resolutions more effectively. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 9600 (120%)

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 information (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
