GeForce GT 130 vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which comes with core clock speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
Radeon RX 470		120 Watts
	Difference: 45 Watts (60%)

Memory Bandwidth

The Radeon RX 470 should in theory be much faster than the GeForce GT 130 overall. (explain)

Radeon RX 470		211200 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 199200 (1660%)

Texel Rate

The Radeon RX 470 will be a lot (more or less 888%) faster with regards to AF than the GeForce GT 130. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 106528 (888%)

Pixel Rate

The Radeon RX 470 is much (approximately 270%) more effective at full screen anti-aliasing than the GeForce GT 130, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 21632 (270%)

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 (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant 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 max fill rate.
