GeForce GT 220 GDDR3 vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which makes use of a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 memory runs at a speed of 1650 MHz on this card. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 220 GDDR3		58 Watts
Radeon RX 470		120 Watts
	Difference: 62 Watts (107%)

Memory Bandwidth

As far as performance goes, the Radeon RX 470 should theoretically be a lot superior to the GeForce GT 220 GDDR3 in general. (explain)

Radeon RX 470		211200 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 178816 (552%)

Texel Rate

The Radeon RX 470 is quite a bit (about 1085%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 108528 (1085%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 470 is a better choice, and very much so. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 24632 (493%)

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 maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface 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 memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
