GeForce GT 130 vs Radeon R9 M385X

Intro

Compare all that to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this particular card. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X, in theory, should be much faster than the GeForce GT 130 overall. (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 anisotropic filtering than the GeForce GT 130. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M385X is superior to the GeForce GT 130, and very much so. (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 (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video 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 most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
