GeForce GT 450 (OEM) vs Radeon RX 460 2GB

Intro

Compare all that to the Radeon RX 460 2GB, which makes use of a 14 nm design. AMD has clocked the core frequency at 1090 MHz. The GDDR5 memory works at a speed of 1750 MHz on this particular card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 16000 (17%)

Texel Rate

The Radeon RX 460 2GB should be a lot (about 222%) better at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 42080 (222%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 450 (OEM) is a better choice, but only just. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 1520 (9%)

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 moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
