GeForce GT 450 (OEM) vs Radeon RX 460

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460		75 Watts
GeForce GT 450 (OEM)		106 Watts
	Difference: 31 Watts (41%)

Memory Bandwidth

The Radeon RX 460, in theory, should be just a bit faster than the GeForce GT 450 (OEM) overall. (explain)

Radeon RX 460		112000 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 16000 (17%)

Texel Rate

The Radeon RX 460 will be much (approximately 222%) faster with regards to anisotropic filtering than the GeForce GT 450 (OEM). (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 450 (OEM) is a better choice, not by a very large margin though. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon RX 460		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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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.
