GeForce GT 130 vs Radeon R9 285

Intro

Compare those specifications to the Radeon R9 285, which comes with core speeds of 918 MHz on the GPU, and 1375 MHz on the 2048 MB of GDDR5 memory. It features 1792 SPUs along with 112 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
Radeon R9 285		190 Watts
	Difference: 115 Watts (153%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 285 should perform quite a bit faster than the GeForce GT 130 in general. (explain)

Radeon R9 285		176000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 164000 (1367%)

Texel Rate

The Radeon R9 285 will be a lot (more or less 757%) more effective at texture filtering than the GeForce GT 130. (explain)

Radeon R9 285		102816 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 90816 (757%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 285 is a better choice, and very much so. (explain)

Radeon R9 285		29376 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 21376 (267%)

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 largest amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling 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 that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
