GeForce GT 220 GDDR3 vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which features GPU clock speed of 1175 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is comprised of 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

GeForce GT 220 GDDR3		58 Watts
Radeon RX 560		80 Watts
	Difference: 22 Watts (38%)

Memory Bandwidth

The Radeon RX 560 should in theory be a lot faster than the GeForce GT 220 GDDR3 overall. (explain)

Radeon RX 560		114688 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 82304 (254%)

Texel Rate

The Radeon RX 560 will be quite a bit (about 652%) better at AF than the GeForce GT 220 GDDR3. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 65200 (652%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 560 is superior to the GeForce GT 220 GDDR3, by far. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 13800 (276%)

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 largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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