GeForce GT 430 vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which makes use of a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this card. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
Radeon RX 460		75 Watts
	Difference: 15 Watts (25%)

Memory Bandwidth

Theoretically, the Radeon RX 460 should perform much faster than the GeForce GT 430 in general. (explain)

Radeon RX 460		112000 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 83200 (289%)

Texel Rate

The Radeon RX 460 is quite a bit (about 445%) more effective at AF than the GeForce GT 430. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 49840 (445%)

Pixel Rate

The Radeon RX 460 will be a lot (approximately 523%) faster with regards to AA than the GeForce GT 430, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 460		17440 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 14640 (523%)

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 moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
