GeForce GT 450 (OEM) vs Radeon RX 460

Intro

Compare those specs to the Radeon RX 460, which has GPU core speed of 1090 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 Raster Operation 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

In theory, the Radeon RX 460 should be 17% quicker than the GeForce GT 450 (OEM) in general, because of its greater bandwidth. (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 a lot (about 222%) more effective at texture 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

The GeForce GT 450 (OEM) will be just a bit (more or less 9%) faster with regards to full screen anti-aliasing than the Radeon RX 460, and also able to handle higher resolutions without losing too much performance. (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 (in units of MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
