GeForce GT 220 GDDR3 vs Radeon RX 460

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 220 GDDR3		58 Watts
Radeon RX 460		75 Watts
	Difference: 17 Watts (29%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 should perform quite a bit faster than the GeForce GT 220 GDDR3 overall. (explain)

Radeon RX 460		112000 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 79616 (246%)

Texel Rate

The Radeon RX 460 should be quite a bit (approximately 510%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

Radeon RX 460		61040 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 51040 (510%)

Pixel Rate

The Radeon RX 460 should be much (about 249%) faster with regards to AA than the GeForce GT 220 GDDR3, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 460		17440 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 12440 (249%)

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 megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
