GeForce GT 130 vs Radeon R9 M385X

Intro

Compare that to the Radeon R9 M385X, which comes with GPU core speed of 1100 MHz, and 4096 MB of GDDR5 memory set to run at 1500 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X should be 700% quicker than the GeForce GT 130 overall, because of its higher data rate. (explain)

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

Texel Rate

The Radeon R9 M385X is much (approximately 413%) faster with regards to 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 is quite a bit (about 120%) faster with regards to anti-aliasing than the GeForce GT 130, and also will be able to handle higher resolutions without losing too much performance. (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: Bandwidth is the max amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
